LED driving power supply based on 2.4G remote control light modulation and color modulation

Abstract

The invention discloses an LED driving power supply based on 2.4 G remote control light modulation and color modulation. The power supply comprises: an LED driving circuit which is connected between the input end of an AC power supply and an LED light source, wherein the LED light source comprises at least two groups of LED lamp strings which are connected in parallel and have different color temperatures; a dimming circuit connected with the LED driving circuit and used for adjusting a current input to the LED light source by the LED driving circuit according to the input PWM signal; a colormodulation circuit connected to the loops of the LED driving circuit and the LED light source and used for adjusting a current input to each LED lamp string according to the input PWM signal; and a master control circuit integrally with a 2.4G wireless transceiver module and connected with a light modulator with 0-10V, wherein the master control circuit outputs PWM signals to the light modulationcircuit and / or the color modulation circuit respectively according to the light modulation and / or color modulation signals from the 2.4G wireless transceiver module or the light modulation signals from the 0-10V light modulator so as to control the light modulation circuit and / or the color modulation circuit to work.

Description

technical field [0001] The present invention relates to an LED drive power supply, more particularly to an LED drive power supply based on 2.4G remote control dimming and color adjustment. Background technique [0002] With the advancement of technology and the improvement of people's living standards, smart home products have gradually entered the lives of ordinary people, and smart home products are becoming more and more popular with consumers.

[0003] At present, the lighting products with remote control function on the market mainly use the infrared remo...

AI Technical Summary

Problems solved by technology

[0003] At present, the lighting products with remote control function on the market mainly use the infrared remote control method. The dimming and color adjustment basically adopts segmental dimming and color adjustment. The infrared remote control method has a short remote control distance, generally only 5- 10m, and only one-to-one control can be performed, and multiple groups of lamps cannot be controlled at the same time, and the infrared remote control still has the problem of remote control dead angle
