イト保護装置。 A conductive line with temperature characteristics is attached to the front or back surface of the lamp lens by a predetermined means, and the terminal of this conductive line is connected to a stop signal generation transistor, and one terminal of this stop signal generation transistor is connected to the temperature of the discharge lamp. It is connected to the lighting circuit that detects and controls the input power to the discharge lamp, and when a break occurs in the conductive line, the stop signal generation transistor is activated and sends a stop signal to the lighting circuit. A headlight protection device using a high-pressure discharge lamp that stops lighting, detects the temperature of the discharge lamp, and controls the power input to the discharge lamp when restarting.
