Description

Illumination light source module with RGB three colors

This creation is related to the light-emitting module of lighting, especially a light source module with RGB three colors.

According to the conventional light source, tungsten bulbs and fluorescent tubes are the main light sources. Since the invention of W-LED (white light LED), the current light source uses white light LED as the main light source of the lighting module However, white LEDs mainly use the blue light produced by ordinary blue LEDs to hit the phosphor to produce yellow light, so that they are emitted from the LED together, we will feel as if we see white light, in fact, this is only blue and yellow. It's just a composite light with mixed colors. Because of this principle, many manufacturers directly increase the intensity of blue light in order to increase the brightness of white light LEDs, but this will cause "excessive blue light." Because high-energy blue light is harmful to human eyes, especially blue light with a wavelength less than 455 nm (below) Short-wave blue light) is more likely to reduce the viability, apoptosis and necrosis of retinal cells, and cause irreversible damage, such as macular degeneration of the retina and damage to the user’s retina. In view of this, the author of this case believes that there is a further step The improvement is necessary, and this creation is born.

The purpose of this creation is to provide a lighting source module with three colors of RGB, which can reduce blue light and achieve the effect of eye protection.

In order to achieve the above purpose, the lighting source module with RGB three colors provided by this creation can be installed in a lamp for lighting purposes. The lighting module is composed of several LED units. Each LED The unit is further composed of at least one red LED, at least one green LED and at least one blue LED LED package composition, among the LED units, each LED of the same color is connected in series with each other, respectively connected to a power drive control unit, each independently controlled, and provides the drive current of each color LED.

The lighting source module with RGB three colors provided by this creation is achieved by changing the light source of the lighting module to red, green and blue LEDs instead of the traditional white LEDs, and use power to drive the control units respectively Independently control the LEDs of each color system to achieve white balance and the best and widest color gamut, and it has the function of reducing blue light and achieving eye protection.

Figure 6 is a schematic diagram of the structure of the LED unit of the second embodiment of this creation.

Please refer to Figures 1 and 2, which are the structural diagram of the LED unit and the circuit diagram of the lighting source module of the first preferred embodiment of this creation. The lighting module 100 is composed of a number of LED units 10 and a number of power sources. It is composed of a drive control unit 20, wherein each LED unit 10 is further packaged by a red LED 11, a green LED 12 and a blue LED 13. The red LED 11, The green LED 12 and the blue LED 13 are grounded separately, and 6 pins 14 are formed on the outside of the LED unit 11 to provide circuit connections. In the LED units 10, after each LED of the same color is connected in series, Each is connected to a power drive control unit 20, and the power drive control unit 20 is independently controlled and can independently provide the drive current of each color LED.

In order to further understand the structural characteristics of this creation, the use of technical means and the expected effects, I hereby describe the usage of this creation. I believe that we can have a deeper and specific understanding of this creation from this, as follows:

Please refer to Figure 3, which is a schematic diagram of a light bar 200 formed in the above-mentioned first preferred embodiment of this creation. The light bar 200 includes a long substrate 201, and the illumination light source modules 100 are along the The long axis direction of the substrate 201 is equidistantly arranged on the substrate 201, whereby the light bar 200 can be used as a light source for lighting fixtures, such as a lamp tube, but this is only an embodiment, not a limitation of this creation In the implementation mode, according to the shape of the lamp, it can also be formed into a light bulb, a circular light bar, a circular or rectangular lamp panel, etc. Please refer to Figure 4, which is a schematic diagram of the first preferred embodiment of the invention applied to the table lamp 300 , The lamp bar 200 is built in the desk lamp 300 as a light source. Please refer to Figure 5 again, which is a schematic diagram of the first preferred embodiment of the invention applied to a fluorescent lamp 400. The light bar 200 is built-in as a light source, but this is only an example, not a limitation of the implementation of this creation. This creation can also be applied to eye protection lamps, bedside lamps, table lamps, standing lamps, On lighting fixtures such as recessed lights or ceiling lights.

Please refer to Figure 6, which is a structural diagram of another preferred embodiment of the creative LED unit. The LED unit 10' is also packaged by a red LED 11', a green LED 12' and a blue LED 13' The difference is that the red LED 11', the green LED 12' and the blue LED 13' in the LED unit 11' are grounded together, so that the LED unit 10' has 4 pins 14' formed on the outside of the LED unit 10' to provide circuit connections .

It can be seen from the above that this creation does have the following advantages:

1. The lighting source module 100 with RGB three colors provided by this creation, by changing the light source 10 to red LED111, green LED112 and blue LED113 to replace the traditional white LED, in addition to reducing blue light, and by The power supply drives the control unit 40 to adjust the ratio of red light, green light and blue light. Since the three primary colors of red, green and blue have higher saturation, a wider color gamut can be obtained to achieve white balance and optimal, The widest color gamut, and has the function of reducing blue light and achieving eye protection.

2. The lighting source module 100 with RGB three colors created by this creation can be applied to all kinds of general lamps, including recessed lamps, ceiling lamps, fluorescent lamps, table lamps, bedside lamps, eye protection lamps and other products as its lighting Use, can also be used as dimming.

To sum up, this creation has its excellent advanced practicality among similar products. At the same time, we have checked the domestic and foreign technical data about this kind of structure, and the same structure has not been found in the literature. Therefore, This creation actually has the requirements for a new patent, and Yan has filed an application in accordance with the law.

However, the above is only one of the preferred and feasible embodiments of this creation, so any equivalent structural changes made in the application of this creation specification and the scope of patent application should be included in the patent scope of this creation.
