Abstract

The invention provides a method to stabilize the output brightness from high brightness light emitting diode. It outputs a driving electric power first to the high brightness light emitting diode module and begins to count the working time of high brightness light emitting diode module. According to the current information and working time of high brightness light emitting diode module, the driving current from the driving electric power of high brightness light emitting diode module is adjusted immediately. The fixed brightness of the high brightness light emitting diode with is achieved by the stable electric current of the high brightness light emitting diode module.
