Problems solved by technology
[0003] LED lamps are generally based on the principle of three primary colors. By controlling the LED array of red, green and blue primary colors, the LED lamps emit light with different color temperatures and brightness. The working stability of LED lamps depends not only on the LED itself, but also on the driving control circuit of the LED. , the existing LED control circuit has poor stability, and it is easy to cause the aging of the LED lamp when controlling the brightness of the LED lamp, thereby reducing the life of the LED lamp

The invention provides a three-primary color multi-color temperature LED street lamp intelligent control system. The input end of a surge protection circuit is connected with the mains supply; the output end of the surge protection circuit is connected with the input end of a rectifier circuit; the output end of the rectifier circuit is connected with the input end of a front-stage power circuit;the output end of the front-stage power circuit is connected with the input ends of a first voltage stabilizing circuit and a second voltage stabilizing circuit; the first voltage stabilizing circuitoutputs 5V DC to provide power for a main controller, an LED control circuit and the front-stage power circuit; the output end of the second voltage stabilizing circuit outputs 9V DC VCC1 to provide power for the LED control circuit; the control end of the LED control circuit is connected with the main controller; and the control end of the front-stage power circuit is connected with the main controller. Stable working power can be provided for the three-primary color multi-color temperature LED lamps, an LED array in the LED lamp can be ensured not to exceed a brightness critical value to emit light, and the LED street lamp can thus be ensured to operate stably and durably.
Description
technical field [0001] The invention relates to the lighting field, in particular to an intelligent control system for LED street lamps with three primary colors and multiple color temperatures. Background technique [0002] With the development of LED technology, LED technology is also widely used in lighting, such as LED street lamps, LED table lamps, etc., because LED has the advantages of strong shock resistance, low heat generation, low energy consumption, and long life. [0003] LED lamps are generally based on the principle of three primary colors. By controlling the LED array of red, green and blue primary colors, the LED lamps emit light with different color temperatures and brightness. The working stability of LED lamps depends not only on the LED itself, but also on the driving control circuit of the LED. , the existing LED control circuit has poor stability, and it is easy to cause the aging of the LED lamp when controlling the brightness of the LED lamp, thereby...
