Abstract:
A light emitting system includes a light emitting device having a forward voltage, and an optical power control device. The optical power control device includes a control signal module and a current controller. The control signal module generates a control signal according to the forward voltage, and the current controller permits flow of a driving current through the light emitting device according to the control signal.
