PURPOSE: A light driving circuit is provided to additionally arrange a circuit that resets the constant current circuit in a driving driver, thereby preventing the damage of the device. CONSTITUTION: A discharge circuit (22) is connected to an output terminal. The discharge circuit discharges the voltage of the output terminal when releasing a lighting load. The output terminal connects the lighting load. A reset circuit (23) resets a control circuit (30) of the output terminal. The reset circuit maintains the constant voltage or the constant current to the output terminal. |
