Abstract
A curing light source device comprises a curing light source module, a drive unit and a current sensor. The curing light source module has at least a series-connected group with at least an LED for emitting light of a specific wavelength. The drive unit is used to drive the curing light source module and provide working power for the curing light source module. The current sensor is connected between the curing light source module and the drive unit, and is used to regulate the current provided by the drive unit for the curing light source module. Through the arrangement manner of the LEDs and the over-current protection function of the current sensor, these LEDs can be prevented from burning out.
