英文摘要	A headlight system can include a laser driving circuit to drive a laser device, a detecting circuit to detect a current of the laser device, a wavelength converting material to emit light having a white color tone associated with the laser device, a receiver circuit to detect a light-intensity of the light via a photo detector and a controller. The controller can control the laser driving circuit while watching normal/abnormal states of an optical structure of the system. Thus, the disclosed subject matter can provide the headlight system, which can provide favorable light distribution patterns by using the light, even when a battery voltage returns the laser device to the normal state after the controller outputs a turn-off signal to the laser driving circuit not to emit the laser device by detecting the abnormal state in the optical structure such as the laser device because the battery voltage largely decreases.
