摘要： A lighting-dimming device has a dimming module with an encoding function and at least one light module with a decoding function and controlled by the dimming module. The dimming module is designated with a required brightness and address command by a user. A triode AC switch of the dimming module is controlled to chop a power based on the required brightness and address command. The chopped power is transmitted to the light module to control the brightness of the light module. In the chopped power, only a part of cycles of the power is chopped and most of the power waveforms are maintained. Therefore, a high power factor is maintained.
