摘要	A vehicle headlight system using a lighting system can include a controller and a lighting unit, which can emit various color lights mixing a wavelength-converted light by a wavelength converting material using a part of a laser beam emitted from a laser light-emitting device as an exciting light with another part of the direct laser beam. The controller can examine a connecting state between the wavelength converting material and a mounting board mounting the wavelength converting material thereon, and also can control to turn off the laser light-emitting device of a laser light source when a threshold, which may be varied in accordance with the connecting state, is less than a value of an acceleration signal, which is caused by shocks. Thus, the presently invention can provide vehicle headlight systems including an eye-safe, which can turn off the laser light-emitting device by anticipating a degradation of the laser light source.
其他摘要	使用照明系统的车辆头灯系统可以包括控制器和照明单元，其可以使用从激光发光装置发射的激光束的一部分通过波长转换材料发射混合波长转换光的各种颜色的光作为激发光与直接激光束的另一部分。控制器可以检查波长转换材料与其上安装波长转换材料的安装板之间的连接状态，并且还可以控制当激光光源的激光发射装置的阈值可以变化时关闭激光发射装置，根据连接状态，小于由冲击引起的加速度信号的值。因此，本发明可以提供包括眼睛安全的车辆头灯系统，其可以通过预见激光光源的退化而关闭激光发光装置。
主权项	A lighting system having a lamp room and a light-emitting direction, comprising: a light source including a laser light-emitting device and a wavelength converting material, and located in the lamp room of the lighting system, the wavelength converting material formed in a planar shape having a light-emitting surface, and facing the laser light-emitting device in an opposite direction of the light-emitting surface of the wavelength converting material, and the light-emitting surface of the wavelength converting material emitting a laser beam having a different light-emitting wavelength from a light-emitting wavelength of a laser beam emitted from the laser light-emitting device after the laser beam emitted from the laser light-emitting device passes though the wavelength converting material; a reflector (21) located in the lamp room, and configured to reflect the laser beam emitted from the light-emitting surface of the wavelength converting material in the light-emitting direction of the lighting system; a circuit board located adjacent the reflector in the lamp room, and located in an opposite direction of the light source with respect to the reflector; an acceleration sensor mounted on the circuit board, located in the light-emitting direction of the lighting system with reference to the light source, detecting a shock as an acceleration rate, and outputting the acceleration rate as an acceleration signal; a controller inputting the acceleration signal from the acceleration sensor (50), and comparing the acceleration signal with a threshold; and characterized in that the controller controls to turn off the laser light-emitting device of the light source when the threshold is less than a value of the acceleration signal.
