Title:
LASER ILLUMINATION LAMP
Document Type and Number:
WIPO Patent Application WO/2020/119354
Kind Code:
A1
Abstract:
A laser illumination lamp (100), comprising a light source assembly (10), a first reflector (20), a wavelength conversion element (30), a light guide element (40), wherein the light source assembly (10) is used for generating and outputting exciting light (11), the first reflector (20) and the wavelength conversion element (30) are provided in the light guide element (40), the first reflector (20) is used for reflecting the exciting light (11) onto the wavelength conversion element (30), the wavelength conversion element (30) is used for converting the exciting light (11) into excited light (12) and reflecting the excited light (12) onto the light guide element (40), and the excited light (12) is emitted after being shaped by the light guide element (40). The first reflector (20) and the wavelength conversion element (30) are provided in the light guide element (40), on one hand, the exciting light (11) can irradiate the wavelength conversion element (30) smoothly, and the excited light (12) can irradiate the light guide element (40) smoothly; on the other hand, the structure of the laser illumination lamp (100) is more compact, the volume is smaller, and the light collection efficiency is higher.
