Abstract:
A lighting circuit for a light source includes a drive circuit that supplies a lamp current to the light source, detects the lamp current, and executes feedback control such that the lamp current approaches a target current, and an overcurrent protection circuit that is inserted between the drive circuit and the light source and that restricts the lamp current flowing into the light source so that the lamp current does not exceed an overcurrent threshold value. The overcurrent protection circuit includes a transistor, an inductor, a rectifier, a current sensor that generates a current detection signal according to the lamp current, and an overcurrent protection controller that controls ON/OFF of the transistor based on the current detection signal and the overcurrent threshold value. The transistor, the inductor and the rectifier are disposed in a T-shape.

Claim (Index 20):
The lighting circuit of  claim 16 , wherein the overcurrent protection controller comprises an OFF-latch circuit that fixes the transistor OFF when a state continues for a predetermined time where the transistor repeatedly switches ON and OFF.
