Abstract:
A lighting circuit utilizes a buck converter that supplies a drive current to a light source and is feedback-controlled so that the drive current comes close to a target current. An open-circuit detection circuit compares a potential difference between and input voltage and an output voltage of the buck converter with a threshold voltage.

Claim (Index 12):
