Abstract:
1. A light emitting device driver circuit, comprising: a light emitting device control circuit, for converting an input voltage to an output voltage according to a control signal and supplying the output voltage to a light emitting device circuit; a voltage supply circuit, which is coupled to the light emitting device circuit, for generating a supply voltage from the output voltage or a voltage related to the output voltage; and a remote control circuit, which is coupled to the voltage supply circuit, for receiving the supply voltage and generating the control signal according a remote signal, wherein when the light emitting device circuit is ON, the light emitting device control circuit regulates a current flowing through the light emitting device circuit, and when the light emitting device circuit is OFF, the light emitting device control circuit regulates the output voltage to a level sufficient for the voltage supply circuit to generate the supply voltage.
