摘要:
A vehicle lighting device includes: an LED light source having a light emitting surface; a laser light source; and a fluorescent body for emitting visible light in response to excitation light from the LED light source and the laser light source, the fluorescent body i) having a rear surface formed to have substantially the same size as the light emitting surface, and a front surface located opposite the rear surface, ii) disposed on the light emitting surface such that the rear surface covers the whole light emitting surface, and iii) emitting the visible light from the whole of the front surface, in response to the excitation light from the LED light source. The laser light source irradiates the excitation light to a portion on the front surface. The portion is to emit the visible light to a high illuminance area within a light distribution pattern.
