Abstract
A road lamp dimming control device comprises a signal processor, a power supplier, a driver and a light emitting module. The single processor is used for receiving an inputted electric current and a control signal. The control signal is decoded into a dimming control signal that then is transmitted to the power supplier. The power supplier converts the inputted electric current into constant current based upon the dimming control signal. The driver receives the constant current to drive the light emitting module to allow the light emitting module having different brightness based upon the control signal, thereby performing multi-stage variation.
