Abstract

A wireless illumination controller with the function to set the lowest driving power includes a microprocessor, a driver, an illumination control switch, and a wireless receiving module. The microprocessor is built in with an adjustable lowest power and connected with the driver, the illumination control switch, the wireless receiving module and a power processing module. The illumination control switch is used to set the lowest power of the microprocessor. After the wireless receiving module receives a wireless illumination adjustment command, the power of the driving signal output from the driver is controlled to be not lower than the lowest power. Therefore, when a user adjusts the illumination, the driving power is never lower than the lowest driving power of the corresponding light bulb, thereby avoiding flickering.
