The light control module has a rectifier, a microcontroller, a Bluetooth IC, and an adjustment button: the microcontroller has a built-in brightness adjustment circuit, a color temperature adjustment circuit, and a control program. The micro-controller The device is connected to the adjustment button and the Bluetooth Between ICs, the microcontroller is triggered to send signals to the Bluetooth IC through the setting of the adjusting button. The adjusting button is a switch that sends signals by pressing and rotating. At least one brightness adjustment is connected to the microcontroller Trigger circuit, a lamp status binding circuit, and a color temperature adjustment trigger circuit. The micro-controller can be triggered to perform different light control modes by pressing and rotating the adjustment button; if so, the user can control the program with a single adjustment button At the same time adjust the brightness and color temperature of most lamps, which not only simplifies the wiring, but also directly reduces the cost of installation; especially, with the use of multi-stage power switches, the brightness and color temperature of the previously lit lamps can be adjusted after the brightness and color temperature are adjusted. Binding, there is no need to make adjustments when you turn on the power switch to enter the same mode next time, so for some special environments such as agronomic facilities or medical places, you can avoid resetting or solving problems that are difficult to restore to the original settings. The main purpose of the present invention is to be able to provide the uniformity of the ambient lighting in the field.
