Title:
ILLUMINATION DEVICE AND AUTOMOBILE HEADLIGHT
Document Type and Number:
WIPO Patent Application WO/2021/012883
Kind Code:
A1
Abstract:
An illumination device (10) comprises an excitation light source (111, 112) and a wavelength conversion unit (120). Excitation light emitted by the excitation light source (111, 112) is incident on the wavelength conversion unit (120), and excites light. The excited light and unabsorbed excitation light exit in a pre-configured direction to form exit light of the illumination device (10). The excitation light source (111, 112) comprises a laser light source unit (111) and an LED light source unit (112). A first light spot (S1) formed by the laser light source unit (111) on a surface of the wavelength conversion unit (120) is covered by a second light spot (S2) formed by the LED light source unit (112) on the surface of the wavelength conversion unit (120). The laser light source unit (111) and the LED light source unit (112) are separately controlled. The structure allows an automobile headlight comprising the illumination device (10) to integrate different illumination light distributions, and reduces the size of the illumination device (10) and the size of the automobile headlight.
