Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention is related to a golf ball with a light-emitting control mechanism, and more particularly, to a golf ball that is capable of emitting light and controlling the light-emitting timer.
2. Description of Related Art
In recent years, golf has become a popular sport and is an excellent choice especially for people who are not able to exercise strenuously. However, when a golf ball is hit and flies away, one has to observe the path of the golf ball. Otherwise, it is difficult for the golfer to find the golf ball. In order to deal with this problem, various techniques have been over the years to make golf balls emit light, for example, adding a fluorescent material into the crust of the balls or installing light-emitting components inside of them.
However, due to limitations in use, the fluorescence in the crust of golf balls gradually fades over time. Furthermore, owing to the property of the fluorescent material, the fluorescent golf balls can only emit light after absorbing sunlight. What's more, the fluorescent light emitted from the fluorescent golf balls is usually inefficient for observing the golf ball when it is hit a significant distance. Hence, the trajectory of fluorescent golf balls is still difficult to track except when it is extremely dark. Tracking is even more difficult when a golf ball is hit a very long distance or is mishit and flies off in an unexpected direction.
Although golf balls having light-emitting components inside have higher brightness, their battery power is easily exhausted because of poorly designed power supplying circuits. Hence their lifetime is generally very short. After being hit, this kind of golf ball emits light constantly until the battery power of built-in battery is exhausted. Even though increasing the number of batteries can prolong the lifetime of this kind of golf ball, the battery power of the battery is still not efficient because the design of the circuit between the batteries is not good.
Accordingly, as discussed above, the prior art still has some drawbacks that could be improved upon. The present invention aims to resolve the drawbacks of the prior art.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a golf ball with a light-emitting control mechanism, which uses a timer to control the length of time the light-emitting components operate for. In this way, the battery power of the irreplaceable batteries will not be used constantly and the lifetime of the batteries is thus prolonged.
Another object of the present invention is to provide a golf ball with a light-emitting control mechanism, which only uses one battery of the battery set to provide battery power for the timer that controls the light-emitting components. In this way, the electric consumption of the battery set is reduced considerably and the lifetime of the battery set is thus prolonged.
Still another object of the present invention is to provide a golf ball with a light-emitting control mechanism, which uses a control chip to make the light-emitting components emit light according to various light-emitting modes. In this way, users can track or observe the trajectory of the golf ball.
For achieving the objects above, the present invention provides a golf ball with a light-emitting control mechanism. The golf ball has a light-permeable inner shell for packaging a light-emitting module. The golf ball further has a light-permeable middle shell for packaging the light-permeable inner shell and a light-permeable outer shell for covering the light-permeable middle shell. The light-emitting module controls at least a light-emitting component and includes a timer, a battery set, and a vibration-sensing switch.
The timer keeps the light-emitting component emitting light constantly until the light-emitting timer expires. The battery set includes a first battery and a second battery. The first battery provides battery power for both the timer and the first battery and the second battery provides battery power for the light-emitting component. The vibration-sensing switch makes the first battery provide battery power for the timer after sensing vibration. After the timer obtains battery power, the timer makes the first battery and the second battery provide battery power constantly for the time-emitting component until the light-emitting timer expires.
Numerous additional features, benefits and details of the present invention are described in the detailed description, which follows.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Reference is made to FIG. 1, which is a schematic diagram of a light-permeable inner shell in accordance with the present invention. As shown in FIG. 1, the golf ball with a light-emitting control mechanism has a light-permeable inner shell 1, which contains a light-emitting module 2 and has a balancing hole 11 for fixing of itself.
The light-emitting module 2 is used mainly for controlling at least one light-emitting component, such as a light-emitting diode (LED) 22 as shown in FIG. 1 or a LED 26 as shown in FIG. 2. It controls the LEDs 22 and 26 by a timer 23, a vibration-sensing switch 24, and a battery set 25 of a circuit board 21.
In brief, when the golf ball of the present invention is hit, the timer 23 is used to control the light-emitting timer of the LEDs 22 and 26 according to a preset parameter. In this way, the LEDs 22 and 26 will not constantly consume the battery power of the irreplaceable battery set 25 and the lifetime of the battery set 25 is thus prolonged. In the following, how to package the light-permeable inner shell 1 into a golf ball and how to use the timer 23 or other components to prolong the lifetime of the golf ball will be described in detail.
Reference is made to FIG. 2, which is a cross-sectional view of the light-permeable inner shell containing the light-emitting module in accordance with the present invention. As shown in FIG. 2, the light-emitting module 2 includes the circuit board 21, the LED 22, the timer 23, the vibration-sensing switch 24, and the battery set 25. Furthermore, the battery set 25 includes a first battery 251, a second battery 253, an isolating board 252 sandwiched between the first battery 251 and the second battery 253, and an isolating board 254 sandwiched between the second battery 253 and the LED 26. The LED 26 is disposed on the isolating board 254.
For packaging, after the light-emitting module 2 is placed into the light-permeable inner shell 1, glue is infused into the light-permeable inner shell 1 via its opening to fix the light-emitting module 2.
Reference is made to FIG. 3, which is a schematic diagram of the golf ball with a light-emitting control mechanism in accordance with the present invention. As shown in FIG. 3, in the present invention, a spherical light-permeable middle shell 3 is first provided to package the light-permeable inner shell 1. Then, a light-permeable outer shell 4 is provided to package the spherical light-permeable middle shell 3 to form a golf ball.
Reference is made to FIGS. 4A-C, which are schematic diagrams of the light-emitting module in accordance with the present invention. As shown in FIG. 4A, the light-emitting module 2 includes the timer 23, the battery set 25 (the first battery 251 and the second battery 253), the vibration-sensing switch 24, the LEDs 22 and 26 that connect to each other in series, and a switch component 27 that is used to protect the timer 23. In the battery set 25, the first battery 251 provides battery power for the timer 23 and both the first battery 251 and the second battery 253 provide battery power for the light-emitting components. In practice, the switch 27 is dispensable and the circuit of the light-emitting module 2 can be simplified as shown in FIG. 4B.
When the golf ball of the present invention is hit, the vibration-sensing switch 24 senses the vibration and is switched on to make the first battery 251 provide battery power to the timer 23 and turn it on. After the timer 23 is activated, it measures time according to a preset light-emitting timer. If both the first battery 251 and the second battery 253 are mercury batteries, each of which provides direct current (DC) battery power with 3V, a loop that has a voltage of 6V and passes through the timer 23 is formed and the first battery 251 and the second battery 253 provide battery power for the light-emitting components. The LEDs 22 and 26 will then emit light. When the preset light-emitting timer expires, the timer 23 stops the first battery 251 and the second battery 253 from providing battery power to the light-emitting components. Hence, the LEDs 22 and 26 turn off.
It should be noted that the vibration-sensing switch 24 is a conventional component and hence not described in detail. In addition, if the number of the light-emitting components, i.e. LEDs 22 and 26, is equal to or larger than two, the light-emitting components can be connected in series as shown in FIG. 4A or in parallel as shown in FIG. 4C.
As for the length of the light-emitting timer, it can be set according to practical requirements. This means that the length of the light-emitting timer can be set according to the length of necessary time consumed in flying, falling, and searching for the golf ball after it is hit. In general, the length of the light-emitting timer is set to about ten minutes.
To sum up, in the present invention, if the batteries of the battery set 25 are connected in series, only one battery, i.e. the first battery 251, provides battery power to the timer 23 that controls the light-emitting timer of the light-emitting components. Hence, electric consumption of the battery set 25 is reduced and the lifetime of the battery set 25 is prolonged. Moreover, since a very bright light is emitted from the LEDs 22 and 26, the amount of light doesn't decrease with time. Hence, when the golf ball is hit and flies a long distance, the trajectory of the golf ball is easily tracked due to the light emitted from the golf ball.
Reference is made to FIGS. 5A-C, which are schematic diagrams of another light-emitting module in accordance with the present invention. As shown in FIG. 5A, the light-emitting module 5 also includes the timer 23, the vibration-sensing switch 24, the LEDs 22 and 26 (light-emitting components) that connect to each other in parallel, and a switch component 27. In addition, the light-emitting module 5 includes a battery set 51. The connection type of the circuit of the light-emitting module 5 is a little different to the light-emitting module 2. The difference is that the two batteries of the battery set 51 are connected in parallel and can provide battery power for the timer 23 and the light-emitting components simultaneously.
As shown in FIG. 5B, in order to provide more light-emitting modes to allow users to easily track the trajectory of the golf ball, the light-emitting module 5 of the present invention further includes a control chip 52. The control chip 52 electrically connects to the LEDs 22 and 26. The light-emitting module 5 not only provides battery power for the LEDs 22 and 26 but also for the control chip 52. Thereby, the control chip 52 is activated.
After the control chip 2 is activated, it can provide two light-emitting modes. The control chip 2 can output signals with different waveforms to the light-emitting components, e.g. the LEDs 22 and 26. Thus, the light-emitting components can twinkle or flicker in various ways. Moreover, the control chip 2 can output signals with different frequencies to the light-emitting components to make them produce various colors.
In order to lower costs, the control chip 52 shown in FIG. 5B can be integrated with the timer 23 as shown in FIG. 5C. In FIG. 5C, although the control chip 52 is integrated with the timer 23, it also connects to the corresponding components. Moreover, the control chip 52 can control and connect with more light-emitting components, such as the LEDs 54 a-c (54 A-C), as shown in FIG. 5D.
Although the present invention has been described with reference to the preferred embodiments thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are embraced within the scope of the invention as defined in the appended claims.
