Technical Field
[0001] The utility model relates to the field of lighting, in particular to a novel CCT color mixing control module. Background Art
[0002] Currently, most LED products with color temperature adjustment have the same number of color temperature at the head and tail, and then achieve the purpose of color adjustment through drive control. Although this method can achieve the conversion of multiple color temperatures, it has the problem of high light source cost. Utility Model Content
[0003] In order to achieve the purpose of color adjustment while significantly reducing the cost of light sources, the utility model provides a novel CCT color mixing control module.
[0004] The present application proposes a novel CCT color mixing control module, comprising: a dip switch and an LED unit; the LED unit comprises: a first LED light string, a second LED light string and a third LED light string, the first LED light string, the second LED light string and the third LED light string are respectively composed of a plurality of LED lamp beads; the dip switch is provided with an interface A, an interface B and an interface C; the interface A is connected to the first LED light string, the interface B is connected to the second LED light string, and the interface C is connected to the third LED light string; the color temperature of the second LED light string is between the color temperature of the first LED light string and the third LED light string.
[0005] Through the technical solution of mixing three different color temperatures, not only can the color adjustment function of the original two-way solution be realized, but also the cost of light sources can be greatly reduced. A middle color temperature is added on the basis of the two color temperatures of the head and tail. If the required color temperature is the head and tail color temperature, the light source of the middle color temperature is switched to the corresponding head and tail color temperature for serial and parallel connection; if the middle color temperature is required, the dip switch is used to serial / parallel three light sources at the same time (which can meet the ANSI 7SDCM color tolerance standard) or serial and parallel two light sources at the head and tail (the color temperature can meet the ANSI 7SDCM color tolerance standard, but cannot meet the ANSI 7SDCM color tolerance standard). This solution can reduce the light source cost by 25% on the basis of the original solution and can realize the color adjustment function of the original solution.
[0006] Preferably, the color temperature of the first LED light string is 2600K, the color temperature of the second LED light string is 3700K, and the color temperature of the third LED light string is 6700K; when the dip switch is connected to interface A and interface B, the first LED light string and the second LED light string are connected; when the dip switch is connected to interface B and interface C, the second LED light string and the third LED light string are connected; when the dip switch is connected to interface A, interface B and interface C, the first LED light string, the second LED light string and the third LED light string are connected.
[0007] Through the above technical solution, the 3000-4000-5000K color-adjusting light effect can be achieved. Compared with the traditional setting of two light sources, one of which is 3000K and the other is 5000K, and each has 20 lamp beads, this solution can reduce the cost of the light source on the basis of realizing the original solution.

Compared with the traditional setting of two light sources, one of which is 4000K and the other is 5700K, and each has 20 lamp beads, this solution can reduce the cost of the light source on the basis of realizing the original solution.
[0012] Specifically, the first LED light string, the second LED light string and the third LED light string are connected in series or in parallel.
[0013] Specifically, the ratio of the number of lamp beads in the first LED light string, the second LED light string and the third LED light string is 1:1:1, but the ratio can be adjusted according to actual conditions and is not limited to 1:1:1.
[0014] The beneficial effects of the utility model are:

[0025] Embodiment 1:
[0026] The following is an example of a three-way simultaneous serial and parallel solution to achieve 3000-4000-5000K:
[0027] If you want to make a 3000-4000-5000K 3CCT color-adjusting whole lamp, the conventional two-way solution is 20 3000K light sources in one way and 20 5000K light sources in one way. The realization of the intermediate color temperature is achieved by mixing the 3000K and 5000K colors through the DIP switch.
[0028] The present application adopts a three-way solution, and the three light sources are the first LED light string, the second LED light string and the third LED light string, which correspond to different color temperatures respectively, and the number of LEDs in each color temperature is 10. When the color temperature is 3000K, the DIP switch is switched to the first LED light string and the second LED light string. At this time, the color temperatures of the two strings are 2600K and 3700K respectively. The mixed color temperature is 3080K. The series-parallel color mixing of the two strings can meet the 3000K requirement; when the color temperature is 5000K, the DIP switch is switched to the second LED light string and the third LED light string. At this time, the color temperatures of the two strings are 3650K and 6700K respectively. The mixed color temperature is 4960K. The series-parallel color mixing of the two strings can meet the 5000K requirement; when the color temperature is 4000K, the DIP switch is switched to the first LED light string, the second LED light string and the third LED light string at the same time. After the series-parallel color mixing of the three strings, the color temperature is 3950K, which can meet the 4000K color temperature requirement and the ANSI standard requirement at the same time. Figure 2 is a color point range diagram of each color temperature according to the first embodiment of the present application.

When the color temperature is 2700K, the DIP switch is switched to the first LED light string and the second LED light string. At this time, the color temperatures of the two strings are 2580K and 2970K respectively. The mixed color temperature is 2750K. The requirement of 2700K can be met by the series-parallel color mixing of the two strings. When the color temperature is 3500K, the DIP switch is switched to the second LED light string and the third LED light string. At this time, the color temperatures of the two strings are 2970K and 3890K respectively. The mixed color temperature is 3410K. The requirement of 3500K can be met by the series-parallel color mixing of the two strings. When the color temperature is 3000K, the DIP switch is switched to the first LED light string, the second LED light string and the third LED light string at the same time. After the series-parallel color mixing of the three strings, the color temperature is 3100K, which can meet the 3000K color temperature requirement and the ANSI standard requirement at the same time. Figure 3 is a color point range diagram of each color temperature according to the second embodiment of the present application.
