Description

DESCRIPTION Technical Area The invention is achieved by structuring a lighting fixture developed with a light-guided plate. The invention particularly focuses on light plate light in luminaires used in the lighting industry. from the light source and/or sources at the edge of the upper and/or lower prismatic structures and the end part by diffraction, reflection and scattering. It provides both direct and indirect lighting by directing it to the desired areas. It is about the configuration of a lighting fixture developed with a light-guided plate.

Invention Background One of the most important factors affecting efficient working in working environments and offices. is lighting. Lighting fixture; suitable light intensity, glare and It should provide parameters such as homogeneity. Specified parameters It provides eye comfort during working.

Unqualified diffusers are used in the products of the current technique. These are from LEDs they do not direct the emitted light. Such non-directed LEDs are desired. Since it cannot create the light pattern, some places become dark in this case; some places remain too bright. That is, the desired homogeneity value cannot be provided. Another important point is changing the angle of the light, directing it, a light It is the use of light that you produce with LED, in short. In this regard, the multi-lens systems are needed. For this reason, the subject of optics is of great importance in its use.

Another problem in the current technique is the formation of bright spots (hot spots) in LEDs and it's a sticking problem. This is because the LEDs give point light. originates. To solve this problem, diffusers with opal additive are used.

It is not possible to direct the light with diffusers with this material.

Suspended luminaires generally provide direct lighting. Darkness of the indirect part remains in the environment creates a contrast and disrupts the homogeneity and reduces eye comfort. affects negatively.

For the above-mentioned reasons, a new one developed with the light-guided plate there was a need for structuring of lighting fixtures.

Purpose of the Invention Starting from this position of the technique, the aim of the invention is to eliminate the existing disadvantages. A new lighting fixture developed with a light-guided plate that eliminates structure is to show.

Another aim of the invention is to provide both direct/indirect lighting in the environment. It is to present a structure that maintains homogeneity and supports eye comfort.

Another aim of the invention is to provide direct and indirect lighting in office environments. to reveal a light guide with optical properties.

Another object of the invention is lighting in accordance with the standards in office environments. is to present a structure that provides its values.

Another object of the invention is to prevent glare and glare of the LEDs. is to present a structure that provides a comfortable view.

Another object of the invention is to prevent the formation of bright spots called hotspots. to present a controlled structure.

Another aim of the invention is to provide users with a much more comfortable lighting fixture. is to put forward a structure that allows them to be used.

It is explained with examples that will not have any limiting effect on the subject.

The invention uses the edge of light plate light in luminaires used in the lighting industry. diffraction, reflection and scattering by the light source and/or sources both direct and indirect lighting structuring of a lighting fixture developed with a light-guided plate (3) that provides its feature is; LED (1) positioned as light source, from said LED* (1) By matching the emitted light to the said light-guided plate (3), you can reduce the light to any loss. optics transmitting parallel to the body of the light-guided plate (3) without touching it The lens (5) is light-guided with the aim of reflecting the said light in the desired shape and angle. the prismatic structure (6) positioned on the lower and/or upper surface of the plate (3) and the said the last part (7), the part where a part of the light is separated from the light-guided plate (3) characterized by its content.

Figure - 1, where the LEDs (1) are placed on the light guide plate (3) which is the subject of the invention. A representative view of the total internal reflection (TIR) optical lens (5) is illustrated.

Figure - 2 prismatic on the light-guided plate (3), which is the subject of the invention. The appearance of the structures (6) is illustrated.

In Figure - 4, the mounted view of the light guide plates (3) which is the subject of the invention, on the profile (8) is pictured.

The subject of the invention is the construction of the lighting fixture; as a light source The positioned LED (1) is an optical one positioned in front of the said LED (1). light-guided plate (3) with a structure, the light emanating from said LED (1) by matching the light-guided plate (3) to a parallel beam without any loss of light. In the figure, the optical lens (5) transmitting the light guide plate (3) towards the body, In order to reflect the light in the desired shape and angle, the light-guided plate (3) is located at the bottom and/or The prismatic structure (6) positioned on its upper surface comes out of the said LED (1). the light (4) diffracted by the optical lens (5) comes out of said LED (1) The light (2) reflected by striking the lower or upper surface of the light-guided plate (3) the last part (7), the part where a part of the light is separated from the light-guided plate (3) as the structure on which the said light-guided plates (3) are fixed the positioned profile (8) is formed on the right and left sides of the said profile (8) plate slot that provides fixing of said light-guided plates (3) (8.1) and fixing the said light guide plates (3) at the desired angle.
