LED light source anti-glare control method, device, electronic equipment and medium

Technical Field

The present application relates to the field of lighting control technology, and in particular to a method, device, electronic equipment and medium for controlling anti-glare of an LED light source.

Background Art

With the accelerated development of industrialization and modernization, LED lighting has been widely used in various work and life scenarios, especially in the industrial and mining fields, due to its high efficiency, long life and environmental friendliness. However, despite the many advantages brought by LED lighting, the glare problem it produces often affects the visual comfort and work efficiency of workers, and may even cause long-term damage to vision. Glare is mainly caused by light directly or indirectly entering the field of vision, which exceeds the brightness range of the human eye's comfortable processing ability.

At present, the existing LED light source anti-glare control method usually uses fixed optical elements such as lenses or reflectors to adjust the light distribution, and shading devices to prevent light from directly hitting the eyes of workers and causing glare. However, in actual applications, due to the wide range of application environments of LED mining lamps and the differences in ambient light in different environments, it is difficult to dynamically adapt to the glare protection requirements in various usage scenarios using fixed optical elements or shading devices, resulting in low accuracy of LED light source anti-glare control.

Summary of the invention

The present application provides a method, device, electronic device and medium for controlling anti-glare of an LED light source, which have the effect of improving the accuracy of anti-glare control of an LED light source.

In a first aspect, the present application provides an LED light source anti-glare control method, which is applied to an LED mining lamp, wherein the inner wall of the LED mining lamp is provided with a foldable free-form surface reflector; the LED light source anti-glare control method comprises:

Determine the glare value corresponding to each of the LED mining lamps according to each of the relative visual angles, the brightness of each of the light sources and the brightness of the ambient light;

Among the LED mining lamps, the LED mining lamp corresponding to the glare value greater than the preset glare value is used as the mining lamp to be adjusted;

Determine the folding angle of the free-form reflector in the mining lamp to be adjusted, and determine the lighting parameters of the mining lamp to be adjusted according to the folding angle and the glare value of the mining lamp to be adjusted;

Based on the lighting parameters, the industrial and mining lamp to be adjusted is controlled to perform lighting.

By adopting the above technical solution, the relative visual angle between the target person and each LED mining lamp, the brightness of each light source and the brightness of the ambient light are obtained, so that the glare effect of each mining lamp on the target person can be accurately determined, and the accurate calculation of the glare value can be achieved. The mining lamps with high glare values are selected as the lamps to be adjusted, and the lighting parameters of the lamps with glare problems can be optimized in a targeted manner. After determining the folding angle of the free-form surface reflector in the lamp to be adjusted, the target lighting parameters are calculated according to the glare value in the folded state, and the optimization parameters considering the folding shape can be obtained. The lamp to be adjusted is controlled based on the calculated target brightness and folding angle. By setting a foldable free-form surface reflector on the inner wall of the LED mining lamp, the lighting parameters of the LED mining lamp can be dynamically adjusted in different LED mining lamp use environments, combined with the ambient light brightness and personnel position, thereby reducing glare and achieving the effect of improving the accuracy of LED light source anti-glare control.

Optionally, the distribution position of the target person in the lighting area is obtained; and the relative visual angle between the target person and each of the LED mining lamps is determined according to the distribution position and the installation position of each of the LED mining lamps in the lighting area.

The installation position of each LED mining lamp is known, and the relative visual angle between the target person and each mining lamp can be accurately calculated in combination with the distribution position of the target person. The visual angle is determined by the relative position relationship between the target person and the mining lamp. The calculation is more accurate and objective, and is not affected by the external ambient light. A more accurate relative visual angle is obtained, and the glare effect of each LED mining lamp on the target person can be more reliably judged, thereby improving the accuracy of the glare value calculation.

Optionally, the relative visual angles, the brightness of the light sources, and the ambient light brightness are substituted into a preset first formula to obtain a glare value corresponding to each LED mining lamp; wherein the preset first formula is:

;

In the formula, represents the glare value of the i-th LED mining lamp, represents the reference constant, represents the service life factor of the i-th LED mining lamp, Indicates the light source brightness of the i-th LED mining lamp, Indicates the light source direction coefficient of the i-th LED mining lamp, represents the distance between the i-th LED mining lamp and the target person, represents the relative visual angle between the i-th LED mining lamp and the target person, Indicates the ambient light brightness.

By adopting the above technical solution and the preset formula for calculating the glare value, the glare value of each LED mining lamp can be directly calculated through a unified mathematical formula. The formula includes the key parameters that determine the degree of glare, such as visual angle, light source brightness, and ambient light brightness. Substituting these obtained parameter values into the formula for calculation, the glare value generated by each LED mining lamp on the target person can be directly obtained. Calculating the glare value through the preset formula can avoid the complexity of actual measurement and improve calculation efficiency. The calculated glare value can accurately determine the glare effect of each LED mining lamp on the target person, providing a basis for subsequent lighting optimization control.

Optionally, the average relative distance between the target person and each of the LED mining lamps is determined according to the distribution position and the installation position of each of the LED mining lamps in the lighting area; the basic glare value corresponding to the average relative distance is matched in a database; the ratio of the ambient light brightness to the area of the lighting area is used as the glare value adjustment amount, and the preset glare value is determined according to the glare value adjustment amount and the basic glare value.

By adopting the above technical solution, the average relative distance between the target person and each LED mining lamp is calculated, and the relative position relationship between the person and the light source can be quantified. The matching relationship between the average relative distance and the basic glare value can be pre-established in the database, and the basic glare value obtained by querying the matching reflects the glare baseline level under the relative distance. The ratio of ambient light to the area of the area is calculated as the adjustment amount, and the preset glare value is determined in combination with the basic glare value. The preset glare value takes into account both the average relative distance and the influence of ambient light. A comprehensive glare judgment standard can be obtained. Using the preset glare value to judge the LED mining lamp with an actual glare value that is too high can achieve accurate identification of glare problems.

Optionally, the surface area of the free-form surface reflector is obtained; based on the surface area and the folding angle, the illumination area of each preset grid area in the free-form surface reflector is determined; based on the glare value and the illumination area of each preset grid area, the illumination of each preset grid area is determined; based on the illumination of each preset grid area, the target light source brightness of the industrial and mining lamp to be adjusted and the target folding angle of the free-form surface reflector in the industrial and mining lamp to be adjusted are determined, and the target light source brightness and the target folding angle are used as lighting parameters of the industrial and mining lamp to be adjusted.

By adopting the above technical solution, the surface area of the free-form reflector can be obtained, and the size of the reflective area can be accurately determined. The actual irradiated area of each grid area can be calculated in combination with the folding angle, and the influence of the folding shape on the illumination range can be determined. The illumination distribution of each grid area is calculated according to the glare value and the irradiated area. By judging the illumination distribution, the target brightness and folding angle of the light source in the folded state can be obtained. The target parameters comprehensively consider the reflector shape and the illumination of each area, and can be adjusted in a targeted manner. Using the target parameters to guide the optimization control of industrial and mining lamps can reduce glare and improve the uniformity of illumination, and realize the intelligent control and adjustment of lighting parameters based on the reflector shape.

Optionally, the glare value and the illumination area of each of the preset grid areas are substituted into a preset second formula to obtain the illumination of each of the preset grid areas; wherein the preset second formula is:

By adopting the above technical solution and the preset formula for calculating illumination, the illumination of each grid area can be directly calculated through a unified mathematical model. The formula contains key parameters that determine illumination, such as glare value and illuminated area. Substituting the values of these parameters into the formula, the illumination distribution of each grid area in the current folded state can be directly obtained. Calculating illumination through a preset formula can avoid complex actual measurements and improve calculation efficiency. The calculation results can clearly reflect the impact of the folding form on the illumination distribution of each area, providing a basis for subsequently determining the light source parameters according to the illumination distribution of each area, and achieving precise control of the lighting effect.

Optionally, based on the illumination of each of the preset grid areas, an average illumination is calculated; the difference between the average illumination and the illumination of each of the preset grid areas is calculated to obtain the illumination difference of each of the preset grid areas; the preset grid areas whose illumination difference is greater than the preset difference are screened out as areas to be adjusted, and the angles corresponding to the areas to be adjusted are matched in a database as the target folding angles; the brightness compensation value corresponding to the average illumination is matched in the database, and the target light source brightness of the industrial and mining lamp to be adjusted is determined according to the brightness compensation value and the light source brightness of the industrial and mining lamp to be adjusted.

By adopting the above technical solution, the illumination data of each grid area is calculated, and the average illumination is calculated based on these illuminations as the average illumination level of the entire reflective surface. Then the illumination of each area is compared with the average illumination to determine the difference between the two, so as to evaluate the illumination uniformity of each area. Areas with illumination differences greater than the preset threshold will be screened out as areas to be adjusted, because the illumination effect of these areas is poor. For each area to be adjusted, the corresponding folding angle value that matches its illumination difference is found in the database to determine the target folding angle that can optimize the illumination of the area. In this way, the two target parameters of folding angle and brightness for the illumination distribution and average level of a specific area can be obtained by calculation, which are used to accurately control the lighting effect of the industrial and mining lamp.

The embodiment of the present application provides an LED light source anti-glare control method.

The method can rely on a computer program to be implemented. The computer program can be integrated into an application or run as an independent tool application. The method can also rely on a single-chip microcomputer to be implemented, and can also run on an LED light source anti-glare control system based on a von Neumann system. Specifically, the method can include the following steps:

Step 101: Obtain the relative visual angle between a target person and a plurality of LED mining lamps in a lighting area, the light source brightness of each LED mining lamp, and the ambient light brightness of the lighting area.

Among them, the lighting area refers to the lighting coverage of the LED light source. In the embodiment of the present application, it can be understood as various indoor and outdoor areas that require lighting, such as underground mines, inside buildings, stadiums, commercial plazas, etc., which are used to provide lighting for people in the area.

LED mining lamps refer to LED light source lighting equipment used in environments such as interiors of buildings, stadiums, and commercial plazas. In the embodiments of the present application, it can be understood as a lighting device equipped with an LED light source. A free-form surface reflector is provided inside the lamp wall. The free-form surface reflector is used to optimize the shape of the outer surface of the workpiece to make the illumination of the inner wall of the lamp cup uniform. A light-proof reflective cover is provided on the outside to greatly reduce the glare value of the mining lamp.

The relative visual angle refers to the angular relationship between the target person and the LED mining lamp. In the embodiment of the present application, it can be understood as the angle between the line connecting the target person's eyes and the LED light source and the target person's line of sight, which is used to indicate the direction of the LED light source received by the target person.

The light source brightness refers to the light intensity parameter emitted by the light source component of the LED mining lamp. In the embodiment of the present application, it can be understood as the brightness value corresponding to the luminous flux of the LED chip, which is used to indicate the luminous effect of the LED light source.

Ambient light brightness refers to the illuminance caused by other natural or artificial light sources in the lighting area except LED mining lamps. In the embodiment of the present application, it can be understood as the ambient background brightness generated by the hole or other lighting in the working area, which is used to indicate the degree of influence of the current ambient light.

Specifically, in order to accurately evaluate and control the glare effect of each LED mining lamp on the target personnel, it is necessary to obtain the relative parameters between each LED mining lamp and the target personnel. Use cameras, RFID and other equipment to obtain the precise position coordinates of the target personnel in three-dimensional space, and calculate the relative visual angle between each target person and each LED mining lamp according to the fixed installation position of the LED mining lamp. The light intensity sensor inside the LED mining lamp detects and collects the light source brightness value of each LED light source in real time. In addition, the ambient light sensor set in the lighting area detects and collects the ambient light brightness of the area. The purpose of obtaining the above three parameters is to input them into the glare calculation formula to evaluate the glare effect value of each LED mining lamp on the target personnel. Comprehensively considering the visual effects generated by the personnel position, the parameters of the light source itself, and the influence of ambient light, it is possible to accurately judge the glare perceived by each person to guide subsequent glare control and improve lighting comfort.

Based on the above embodiment, as an optional embodiment, in step 101: obtaining the relative visual angle between the target person and the multiple LED mining lamps in the lighting area, this step may also include the following steps:

Step 201: Obtain the distribution position of the target person in the lighting area.

Among them, the distribution position refers to the coordinate point of the target person in the three-dimensional space. In the embodiment of the present application, it can be understood as the precise three-dimensional coordinates of the target person's head in the lighting area, which is used to indicate the three-dimensional spatial position of the person.

Specifically, in order to calculate the relative visual angle between each target person and each LED mining lamp, it is necessary to first obtain the precise distribution position of the target person in three-dimensional space. Cameras, RFID sensors, lidar and other equipment are set up in the lighting area, and the three-dimensional position data of each target person in the area is detected and collected in real time through image recognition, RFID tag positioning or spatial coordinate measurement. The purpose of obtaining the position of the target person is to determine the spatial relative relationship between the person and each LED mining lamp, and then calculate the visual angle parameters. Only by clarifying the three-dimensional distribution of the target person can the visual effect between the light source and the person be evaluated, and personalized anti-glare control for each person can be achieved. By accurately obtaining the position information of the target person, basic data support can be provided for calculating key parameters such as visual angle.

Step 202: Determine the relative visual angle between the target person and each LED mining lamp according to the distribution position and the installation position of each LED mining lamp in the lighting area.

Among them, the installation position refers to the fixed coordinate point of the LED mining lamp in the lighting area. In the embodiment of the present application, it can be understood as the precise three-dimensional coordinates of the light source component of the LED mining lamp in the area, which is used to indicate the spatial position of the mining lamp.

Specifically, two sets of three-dimensional coordinate data are input into the preset visual angle database, and after matching, the spatial angle value between each target person and each LED mining lamp, that is, the relative visual angle, can be obtained. The purpose of calculating the visual angle is to determine the direction of each LED light source received by the target person's eyes, which is directly related to the degree of stimulation of the light to the human eye. By accurately calculating the visual angle parameters, it can provide key input data support for the subsequent glare control algorithm, and realize quantitative analysis of the glare impact on individual personnel.

Step 102: Determine the glare value corresponding to each LED mining lamp according to each relative visual angle, each light source brightness and ambient light brightness.

Among them, the glare value refers to the quantitative parameter of the degree of glare generated by the LED mining lamp light received by the target person. In the embodiment of the present application, it can be understood as a glare impact index calculated based on the position of the target person, LED light source parameters and ambient light parameters, which is used to judge whether the LED light source has glare beyond the tolerable range.

Specifically, the three parameters of relative visual angle, brightness of each light source and brightness of ambient light are substituted into the pre-established glare impact calculation formula for calculation. This formula comprehensively considers the impact of viewing angle, light source brightness and ambient light on glare, and can quantitatively evaluate the glare perception value of the target person for each LED light source. The purpose of calculating the glare value is to determine whether the LED mining lamp produces strong glare beyond the tolerable range. Only by calculating the glare impact of each light source on the target person can the parameters of the problematic light sources be adjusted in a targeted manner to achieve accurate glare prevention and control. By calculating the glare value, it can be determined which light sources may cause glare to exceed the limit, so as to optimize the lighting parameters in a direction and realize customized adjustment of the lighting environment for individual target persons.

Based on the above embodiment, as an optional embodiment, in step 102: determining the glare value corresponding to each LED mining lamp according to each relative visual angle, each light source brightness and ambient light brightness, this step may also include the following steps:

Step 301: Substitute each relative visual angle, each light source brightness, and ambient light brightness into a preset first formula to obtain a glare value corresponding to each LED mining lamp; wherein the preset first formula is:

;

In the formula, represents the glare value of the i-th LED mining lamp, represents the reference constant, represents the service life factor of the i-th LED mining lamp, Indicates the light source brightness of the i-th LED mining lamp, Indicates the light source direction coefficient of the i-th LED mining lamp, Indicates the distance between the i-th LED mining lamp and the target person, represents the relative visual angle between the i-th LED mining lamp and the target person, Indicates the ambient light brightness.

Among them, the preset first formula refers to a mathematical formula for calculating the glare value of each LED mining lamp. In the embodiment of the present application, the preset first formula can be understood as a multivariate analysis formula that includes factors such as the relative visual angle between each LED mining lamp and the target person and the brightness of the light source, the ambient light brightness of the environment in which each LED mining lamp is located, etc. The preset first formula is used to quantitatively calculate and evaluate the glare value of each LED mining lamp. By substituting the actual detection data, the glare value of each LED mining lamp can be calculated.

Specifically, after obtaining the relative visual angle between the target person and each LED mining lamp, the real-time brightness of the LED light source, and the ambient light brightness, these three parameters need to be substituted into the preset glare calculation formula to obtain the glare value of each LED mining lamp corresponding to each target person. Substituting the three data into the glare calculation formula that comprehensively considers the effects of viewing angle, light source brightness, and ambient light, the glare impact index of each LED light source on each person can be obtained after calculation. The purpose of glare value calculation is to determine whether each LED light source has strong glare that exceeds the acceptable threshold, thereby guiding subsequent light source control.

The formula consists of three parts. The first part describes the distance and relative viewing angle between the LED mining lamp and the target person, as well as the influence of the light source brightness on the glare value. The service life factor of the i-th LED industrial and mining lamp is an adjustment factor used to reflect the light decay and aging effect of the lamp as it is used. After many years of use, the brightness of the lamp may decrease, thus affecting its glare value. Service life factor Adjusted the effect of this change on glare values. Represents the distance between the luminaire and the target person. The farther the distance, the more the light attenuates during propagation, so the glare value will decrease. In the formula, the square of the distance represents the inverse square relationship of the distance, emphasizing the significant effect of distance on the glare value. Relative visual angle Indicates the relative visual angle between the luminaire and the target person. The larger this angle is, the less direct the light enters the line of sight, and the glare value may be reduced.

To avoid division by zero when the angle is zero or very small, a positive number approaching zero is introduced into the formula .pass , ensuring that even is zero, the formula is still valid. is the light intensity emitted by the lamp, and the light source direction coefficient reflects the directional characteristics of the light source. The product of the two represents the effective brightness of the lamp in a specific direction, which has a direct impact on the calculation of the glare value. This part comprehensively considers the age of the lamp, the distance from the target person, the visual angle, and the brightness and directionality of the light source. Through the combined effect of these factors, the glare value of the lamp can be accurately calculated, providing a basis for optimizing the design and installation of the lamp. In practical applications, this part of the formula helps engineers and designers evaluate and reduce the glare effect of lamps, thereby improving the comfort and safety of the lighting environment.

The second part is mainly used to ensure that the entire glare value calculation formula can be reasonably applied under various possible visual angles and distance conditions, and to prevent division by zero. Minimum value function choose and When the viewing angle This part ensures that the formula still works when the visual angle is very small, avoiding outliers when the visual angle is zero. choose and This part ensures that even if When it is very small, there is still a positive lower limit in the formula to avoid The calculation is unstable due to too small a value. This part of the formula smoothes the influence of visual angle and distance on the glare value by selecting the minimum and maximum value functions to ensure the stability and rationality of the calculation.

The third part describes the influence of ambient light brightness on glare value. Considering the influence of background light on glare makes the calculation result more accurate. As an additive term, it represents the background light brightness in the external environment. A higher ambient light brightness will reduce the relative impact of glare, thereby adjusting the final glare value to make it more consistent with the actual observed effect.

In summary, the first preset formula takes into account multiple factors such as the age of the lamp, light source brightness, directionality, distance, visual angle and ambient light brightness. Through complex mathematical processing, such as limits, the universality and rationality of the formula are ensured, and the glare value of each LED mining lamp is finally calculated. Through these calculations, the installation and use of lamps can be better designed and adjusted, the lighting effect can be optimized, and the impact of glare on target personnel can be reduced.

Step 103: Among the LED mining lamps, the LED mining lamps having glare values greater than the preset glare value are selected as the mining lamps to be adjusted.

Among them, the industrial and mining lamp to be adjusted refers to the LED industrial and mining lamp that needs to be adjusted and optimized for parameters. In the embodiment of the present application, it can be understood as an LED industrial and mining lamp whose calculated glare value is higher than a preset threshold, which is used to distinguish the light source whose parameters must be adjusted.

Specifically, the glare value calculated by each LED mining lamp is compared with the preset glare value, and the LED mining lamp with a glare value greater than the preset glare value is determined as the mining lamp whose parameters need to be adjusted. The purpose of judging whether the glare value exceeds the standard is to find out the LED mining lamps that must be parameter-tuned to reduce their glare effects on the target personnel. Only by distinguishing the light sources that must be adjusted can the parameters be controlled in a targeted manner to improve the anti-glare effect. By comparing with the threshold to determine the light source to be adjusted, the lighting parameters can be optimized in a direction, and the LED mining lamps that exceed the tolerable glare level can be adjusted to a comfortable range, thereby effectively solving the glare problem of the target personnel.

Based on the above embodiment, as an optional embodiment, in step 103: among the LED mining lamps, the LED mining lamps corresponding to the glare value greater than the preset glare value are taken as the mining lamps to be adjusted. Before this step, the following steps may also be included:

Step 401: Determine the average relative distance between the target person and each LED high bay light according to the distribution position and the installation position of each LED high bay light in the lighting area.

Among them, the average relative distance refers to the average spatial distance between the target person and the LED mining lamp. In the embodiment of the present application, it can be understood as the mean distance measured between the head of the target person and each LED light source, which is used to represent the distance relationship between the person and the light source.

Specifically, two sets of coordinate data are input into the distance calculation formula. After algorithm calculation, the average spatial distance between each target person's head and each LED mining lamp can be obtained. The purpose of calculating the average relative distance is to determine the distance relationship between the person and the light source, which is related to the illumination and energy of the light received. Only by clarifying the distance parameters can the impact of light on the human eye be correctly evaluated. By accurately calculating the average relative distance, the relationship between the light source and the person can be more comprehensively analyzed, providing richer reference data for subsequent lighting control.

Step 402: Match the basic glare value corresponding to the average relative distance in the database.

The database refers to a structured file collection storing data, which can be understood as a data table storing the matching relationship between distance and basic glare value in the embodiment of the present application, and is used to query the basic glare level that may be generated by the light source under different distance conditions.

The basic glare value refers to the normal glare level that a light source may produce at a specific average relative distance under standard environmental conditions. In the embodiment of the present application, it can be understood as the standard glare value obtained by querying from a preset database, which is used to provide a glare benchmark under current distance conditions.

Specifically, the calculated average distance is used as a search keyword to search in the database that stores the distance-glare value matching relationship to obtain the expected basic glare value level at the average distance. The purpose of searching for the basic glare value is to obtain the benchmark of the glare impact that may be caused by a normal light source under the distance condition. Only by clarifying the benchmark level can we compare the difference between the current actual glare value and the benchmark, and judge the necessity of adjusting the light source parameters. By looking up the table to obtain the basic glare value corresponding to the distance, we can effectively evaluate the severity of the glare problem in the current lighting environment, provide a benchmark basis for the subsequent optimization of the light source control parameters, and further improve the anti-glare effect.

Step 403: taking the ratio of the ambient light brightness to the area of the illuminated area as the glare value adjustment amount, and determining a preset glare value according to the glare value adjustment amount and the basic glare value.

Among them, the glare value adjustment amount refers to the adjustment coefficient calculated based on the ambient light and the area of the area. In the embodiment of the present application, it can be understood as the ratio of the ambient light brightness to the area of the illuminated area, which is used to dynamically adjust the basic glare value, thereby determining a reasonable preset maximum glare threshold.

The preset glare value refers to the maximum acceptable glare threshold determined after considering the current environmental conditions. In the embodiment of the present application, it can be understood as the final glare control target value after adjusting the ambient light and regional area, which is used to determine whether the actual glare value exceeds the standard and whether the light source parameters need to be adjusted.

Specifically, after obtaining the current ambient light brightness and the determined lighting area, it is necessary to calculate the ratio of the two as the adjustment factor of the glare value, and then multiply the adjustment factor by the basic glare value obtained from the database query. After calculation, a reasonable preset glare threshold value in this specific environment can be determined. The purpose of calculating the ratio of ambient light brightness to regional area as the adjustment amount is to consider the impact of ambient light and spatial factors on glare perception. The introduction of these two parameters can make the preset maximum glare value more in line with the actual situation and the setting more reasonable. Multiplying the adjustment amount by the basic glare value can correct the baseline glare value to make it more suitable for the current environment. Finally, an optimized preset glare threshold obtained after comprehensive consideration of various factors is determined to provide a basis for subsequent judgment of whether the actual light source glare value exceeds the standard.

In the embodiments of the present application, they can be understood as parameters that affect the illumination and lighting range, such as the brightness of the light source and the folding angle of the free-form surface reflector. They are used to optimize the combination according to the folding angle and the glare value to achieve adjustable control of the lighting performance of the industrial and mining lamps.

Specifically, the real-time folding angle data of the reflector is collected, combined with the glare value of the lamp to be adjusted, and the optimal lighting parameter combination under the conditions of the angle and glare value, such as light source brightness, beam angle, etc., is found according to the preset mapping relationship. The purpose of optimizing the adjustment parameters is to reduce the glare value of high-glare industrial and mining lamps and control it within a comfortable range. Determining parameters based on the folding angle and glare value can achieve precise control and make the lighting more comfortable. Through this step, the parameters of the industrial and mining lamps to be adjusted with excessive glare can be fine-tuned to effectively solve the glare problem of the target personnel and improve the lighting quality.

Based on the above embodiment, as an optional embodiment, in step 104: determining the lighting parameters of the mining lamp to be adjusted according to the folding angle and the glare value of the mining lamp to be adjusted, this step may also include the following steps:

Step 501: Obtain the surface area of the free-form surface reflector; and determine the irradiation area of each preset grid area in the free-form surface reflector according to the surface area and the folding angle.

The surface area refers to the total reflective surface size of the reflective element, which can be understood as the actual reflective area of the free-form reflective plate in the embodiment of the present application, and is used for the subsequent calculation of the illumination parameters of each grid area of the reflective surface.

The preset grid area refers to a grid area that divides the surface of the reflector into equal parts. In the embodiment of the present application, it can be understood that the free-form surface reflector is divided into multiple local small areas according to certain rules, which is used to calculate the effective illumination area of each grid area under different folding forms.

The illuminated area refers to the area size that each grid area of the reflector can produce effective lighting coverage under specific folding angle conditions. In the embodiment of the present application, it can be understood as the target plane area that can be illuminated by the light reflected from each preset grid area, which is used to evaluate the lighting range and effect of the grid area in the folded form.

Specifically, the total surface area of the free-form reflector installed on the LED mining lamp is measured. Then, according to the detected current folding angle of the reflector, the pre-established mathematical model is used to calculate the effective irradiation area size of each grid area on the surface of the reflector divided into equally divided grids at this folding angle. The purpose of measuring the surface area and determining the folding angle is to obtain the current basic optical characteristic parameters of the reflector, which is a necessary condition for calculating the effective irradiation area of each grid area. Through simulation calculation, the illumination range and effect distribution of each grid area in the folded form can be obtained, so that the specific illumination distribution effect of different local areas of the reflector in the current folded state can be clarified. This refined grid area illumination analysis is carried out to enable more accurate and targeted illumination optimization of the illumination effect of each area in the future.

Step 502: Determine the illumination of each preset grid area according to the glare value and the illumination area of each preset grid area.

Here, illumination refers to the intensity of light, which can be understood as the illumination intensity per unit area generated by the light reflected by each preset grid area of the free-form surface reflector in the embodiment of the application, and is used to evaluate the lighting effect of each grid area for local lighting control.

Specifically, the measured overall glare value of the industrial and mining lamp and the illuminated area of each grid area are used as input, and the mathematical model established by the ray tracing algorithm is used for simulation calculation to obtain the specific illumination distribution of each grid area in this folded state. The illumination of each grid area is calculated to evaluate the impact of the change in folding shape on the light distribution and to clarify the specific illumination conditions of each local area at different folding angles, so as to more accurately guide the parameter adjustment of the light source.

Based on the above embodiment, as an optional embodiment, in step 502: determining the illumination of each preset grid area according to the glare value and the illumination area of each preset grid area, this step may also include the following steps:

Step 512: Substitute the glare value and the illumination area of each preset grid area into a preset second formula to obtain the illumination of each preset grid area; wherein the preset second formula is:

;

In the formula, represents the illumination of the i-th preset grid area, represents the irradiation area of the i-th preset grid area, Indicates the reference luminous flux of the free-form reflector in the mining lamp to be adjusted. Indicates the relative angle between the i-th preset grid area and the light source in the mining lamp to be adjusted, represents the glare value coefficient, Indicates the glare value of the mining lamp to be adjusted. Indicates the relative distance between the i-th preset grid area and the light source in the mining lamp to be adjusted.

The preset second formula refers to a mathematical formula for calculating the illumination of each preset grid area. In the embodiment of the present application, the preset second formula can be understood as a multivariate analysis formula including factors such as the irradiation area of each preset grid area and the glare value of the industrial and mining lamp to be adjusted. The preset second formula is used to quantitatively calculate and evaluate the illumination of each preset grid area. By substituting the actual detection data, the illumination of each preset grid area can be calculated.

Specifically, the glare value obtained and the illumination area data of each preset grid area at the current folding angle obtained by calculation are substituted into the pre-established mathematical formula for calculating illumination as known parameters, and the specific illumination distribution of each grid area under the folding form can be simulated and calculated. The preset formula for calculating illumination is used here to directly obtain the illumination result of each grid area through the established mathematical model. The parameters in the preset formula reflect the key factors that determine the illumination. Substituting the glare value and the illumination area of each area, and using the preset formula to calculate the illumination of each grid area, the purpose is to evaluate the impact of the change in folding form on the light distribution of the grid area, obtain the specific illumination conditions of each local area in the folded state, and provide a basis for subsequent local illumination control.

The formula consists of three parts. The first part describes the effect of the irradiation area of each preset grid area on the illuminance. Represents the illumination area of the i-th preset grid area. This area refers to the area where the light source light is distributed in this specific area. This part represents the distribution of the luminous flux to the area of a specific area. It is the luminous flux per unit area, so the total luminous flux needs to be divided by the area of the area to calculate the illumination per unit area.

The second part describes the influence of the reference luminous flux of the free-form surface reflector, the relative angle between the preset grid area and the light source in the industrial and mining lamp to be adjusted, and the relative distance between the preset grid area and the light source in the industrial and mining lamp to be adjusted on the glare value. It indicates the reference luminous flux of the free-form reflector in the mining lamp to be adjusted. It is the total luminous flux emitted by the light source. This value represents the overall luminous ability of the light source. Indicates the relative distance between the i-th preset grid area and the light source in the industrial and mining lamp to be adjusted. The farther the distance is, the more the luminous flux will diffuse during the propagation process, resulting in reduced illumination. Indicates the relative angle between the i-th preset grid area and the light source in the mining lamp to be adjusted. This angle affects the intensity of the light reaching the area. The greater the angle between the light and the vertical direction, the greater the illumination. decreases with the change of .

This part indicates the effective luminous flux of the total luminous flux of the light source after the angle is adjusted. Through the angle After adjustment, multiply by , which represents the effect of the angle between the light and the surface normal on the illumination. When the light is incident vertically, is 0, so is 1, and the luminous flux remains unchanged. When the light is incident at an oblique angle, Increase, so Decreases, and the effective luminous flux decreases. This part shows the attenuation of the luminous flux as the distance increases during the propagation process. According to the inverse square law, the light intensity is inversely proportional to the square of the distance, which means that the farther the distance, the luminous flux (illuminance) per unit area will be significantly reduced.

This whole part calculates the total luminous flux of the light source after angle adjustment and distance attenuation. The incident angle of the light will affect the illumination. The larger the angle (the more oblique), the lower the illumination. The farther the distance, the sparser the distribution of the luminous flux per unit area, and the lower the illumination. This part comprehensively considers the total luminous flux of the light source, the angle and distance of the light reaching the preset area, and calculates the adjusted effective luminous flux.

The third part describes the influence of the glare value of the industrial and mining lamp to be adjusted on the contrast. Indicates the glare value of the industrial and mining lamp to be adjusted. Glare refers to the visual discomfort or visual obstruction caused by the light emitted by the light source. It is a quantitative indicator used to measure the degree of glare produced by a light source. Represents the glare value coefficient, which is a dimensionless coefficient used to adjust the impact of glare on lighting. It reflects the impact of glare value on the final illumination.

This part indicates the glare value Glare value coefficient After adjustment, the degree of influence on contrast is Large (glare effect is obvious), then will also be larger, indicating that the negative impact of glare on contrast is greater. Small (glare effect is not obvious), then It will also be smaller, indicating that the negative impact of glare on illumination is smaller.

This part represents the effective luminous flux ratio after deducting the glare effect. When there is no glare effect, that is, When the glare effect is strong, that is, If the luminance is larger, this part will be reduced, indicating that the effective luminous flux will be reduced and the illuminance will be significantly affected. The function of this part of the formula is to correct the influence of glare on the illuminance. By subtracting the influence of the glare effect, the effective luminous flux ratio after deducting the glare is obtained, so as to more accurately calculate the actual effective illuminance.

Step 503: based on the illumination of each preset grid area, determine the target light source brightness of the mining lamp to be adjusted and the target folding angle of the free-form surface reflector in the mining lamp to be adjusted, and use the target light source brightness and the target folding angle as the lighting parameters of the mining lamp to be adjusted.

Among them, the target light source brightness refers to the ideal brightness value of the light source obtained after calculation and optimization. In the embodiment of the present application, it can be understood as the set brightness of the light source for reducing glare, which is used as the brightness control parameter of the light source to be adjusted to optimize the lighting effect by adjusting the brightness of the light source.

The target folding angle refers to the optimal folding shape angle of the reflector determined by calculation. In the embodiment of the present application, it can be understood as a reflector folding parameter used to optimize the lighting effect, which is used as the folding angle control value of the light source to be adjusted, and the light distribution is improved by adjusting the folding angle.

Specifically, based on these illumination data, the optimization algorithm can be used to calculate the optimal target light source brightness value and the optimal target folding angle value of the free-form reflector under the current conditions for the lamp to be adjusted. The purpose of calculating the optimized target parameters is to comprehensively consider reducing glare and ensuring illumination, and to obtain the optimal combination of the two key parameters of light source brightness and reflector folding angle, so as to accurately guide the optimization of the lighting effect of the lamp to be adjusted. The calculated target brightness value and target folding angle value are output as the control parameters of the lamp to be adjusted. Subsequently, the light source brightness and reflector curvature of the lamp can be adjusted according to these two target parameters to reduce glare problems and improve lighting comfort. By determining the target parameters according to the specific illumination distribution of each area, the lighting effect can be accurately controlled and optimized, effectively improving the lighting quality of industrial and mining lamps.

Based on the above embodiment, as an optional embodiment, in step 503: based on the illumination of each preset grid area, determining the target light source brightness of the mining lamp to be adjusted and the target folding angle of the free-form surface reflector in the mining lamp to be adjusted, this step may also include the following steps:

Step 513: Calculate the average illumination based on the illumination of each preset grid area; calculate the difference between the average illumination and the illumination of each preset grid area to obtain the illumination difference of each preset grid area.

Among them, the average illuminance refers to the arithmetic mean of the illuminance of all grid areas of the reflective surface. In the embodiment of the present application, it can be understood as the average level of illuminance of all preset grid areas of the free-form surface reflector, which is used as a benchmark for evaluating the illuminance distribution of each area.

The illuminance difference refers to the difference between the illuminance of each preset grid area and the average illuminance. In the embodiment of the present application, it can be understood as the numerical difference between the illuminance of each grid area and the average illuminance of the reflective surface, which is used to evaluate the illuminance distribution of each area.

Specifically, after calculating the illumination of each preset grid area, it is necessary to calculate the average illumination of all grid areas, that is, the average illumination of the entire reflective surface. Then compare the specific illumination value of each grid area with the calculated average illumination, and you can get the difference between the illumination of each grid area and the average illumination. The average illumination and the illumination difference are calculated to evaluate the illumination distribution of each area and find out the local areas with high or low illumination. By comparing with the average illumination, it can be clear which areas have high illumination and may cause glare problems, and which areas have weak illumination and need to increase the illumination. These illumination differences can guide the subsequent optimization and adjustment of the lighting effects of local areas. Obtaining the illumination difference of each grid area can achieve more refined control of the lighting distribution, improve the problem of uneven lighting in a targeted manner, and improve the lighting quality of industrial and mining lamps.

Step 523: Filter out a preset grid area whose illumination difference is greater than a preset difference as the area to be adjusted, and match the angle corresponding to the area to be adjusted in the database as the target folding angle.

Among them, the area to be adjusted refers to a preset grid area where the folding angle needs to be adjusted. In the embodiment of the present application, it can be understood as a grid area where the illumination difference exceeds the threshold, which is used to optimize the folding angle parameters to adjust the lighting effect.

Specifically, the illumination difference of each preset grid area is calculated. Then, those grid areas whose illumination difference exceeds the preset threshold are screened out, and these areas can be regarded as areas to be adjusted. For these areas to be adjusted, it is necessary to find the corresponding folding angle value that matches the size of its illumination difference in the database, and set the folding angle that matches its illumination difference as the target folding angle of the area to be adjusted. In this way, the area with uneven illumination distribution can be judged by comparing with the average illumination, so as to make targeted folding angle adjustments. The mapping relationship in the database can directly obtain the folding angle parameters required to optimize the illumination of each area to be adjusted, and finally output the target folding angle of each area to be adjusted, which can specifically guide the folding angle control of the area, effectively eliminate the illumination difference between areas, and make the illumination distribution in the industrial and mining lamps to be adjusted tend to be uniform, thereby reducing the impact of glare.

Step 533: Match the brightness compensation value corresponding to the average illumination in the database, and determine the target light source brightness of the industrial and mining lamp to be adjusted according to the brightness compensation value and the light source brightness of the industrial and mining lamp to be adjusted.

Among them, the brightness compensation value refers to the light source brightness adjustment amount corresponding to the average illuminance, which can be understood in the embodiment of the present application as an illuminance matching increment used to supplement the current light source brightness, and is used to be added to the current brightness to obtain the target light source brightness.

Specifically, the average illuminance of the entire reflective surface of the mining lamp is calculated. Then, it is necessary to search for a brightness compensation value that matches this average illuminance value in a preset database. A mapping relationship between average illuminance and brightness compensation value is established in the database. After finding the matching brightness compensation value, add this compensation value to the current light source brightness of the mining lamp to obtain the final target light source brightness of the mining lamp. In this way, the average illuminance is used to determine whether the light source brightness needs to be adjusted, and the compensation value in the database is obtained to calculate the target brightness. This not only takes into account the current brightness, but also introduces a compensation amount that matches the average illuminance. A more optimized target light source brightness can be obtained. Obtaining the target brightness can effectively guide the adjustment of the light source brightness, so that the light source output is more in line with the current lighting needs and improves the lighting comfort.

Step 105: Based on the lighting parameters, control the mining lamp to be adjusted to perform lighting.

Specifically, two key lighting parameters, namely, the target light source brightness and the target folding angle of the industrial and mining lamp to be adjusted, are obtained by calculation. With these two optimized and calculated target lighting parameters, it is necessary to actually control the working state of the industrial and mining lamp to be adjusted based on these parameters, that is, adjust the light source brightness output of the industrial and mining lamp to the target brightness value, and drive the free-form surface reflector to adjust to the target folding angle, so that the industrial and mining lamp can be illuminated according to the calculated and optimized target parameters, and its light source brightness and folding angle can be controlled to a better working state, which helps to reduce glare and improve light distribution.
