Title:
発光制御を有するレーザベースの光源
Document Type and Number:
Japanese Patent JP6800224
Kind Code:
B2
Abstract:
The invention describes a laser-based light source (100) which is adapted to use the angular dependence of the reflection of polarized laser light (10) at a surface of a conversion material to control especially the color point of light emitted by means of the laser-based light source (100). The reflected laser light is within a first wavelength range and the converted light is in a second wavelength range different from the first wavelength range such that the color point of the light emitted by means of the laser-based light source (100) in a defined solid angle depends on the ratio between reflected and converted light. The invention further describes a corresponding method of light emission control, a vehicle headlight (200) comprising such a laser-based light source (100) and a lighting system comprising such vehicle headlights (200).
