Abstract:
Provided is a light source drive device including: a current supply device; and a light source device including a light emitting element that emits light by receiving drive current supplied from the current supply device, a temperature sensor that performs temperature detection at a position closer to the light emitting element than the current supply device, and a signal generation unit that outputs a control signal for controlling the drive current depending on a detected value of the temperature sensor to the current supply device. The signal generation unit generates a control signal for reducing the drive current depending on a temperature when the temperature detected by the temperature sensor is equal to or higher than a predetermined temperature.

Claim (Index 5):
A light source drive device comprising:\n a temperature acquisition unit including a light emitting element and a temperature sensor that detects a temperature near the light emitting element, the temperature acquisition unit performing a first processing of acquiring detection information of the temperature sensor when lighting of the light emitting element starts and a second processing of acquiring detection information of the temperature sensor at a time point at which a predetermined time has passed from the start of lighting; and a determination unit that performs determination of abnormality of the temperature sensor by determining a change in the detection information acquired in the first processing and the detection information acquired in the second processing.
