Document Type and Number:
WIPO Patent Application WO/2023/171477
Kind Code:
A1
Abstract:
Provided is a vehicle light that can illuminate a desired area with a desired brightness without making the optical system complex, even in a case where a light source is a single multi-split LED array. The present invention comprises: a light source (multi-split LED array) (3) in which a large number of light emitting elements (micro-LEDs (31)) are arranged, and which select the light emitting elements for light emission to emit light of a desired pattern; and a main optical system (2) for projecting light emitted from the light source to form a main light distribution pattern. The present invention further comprises an auxiliary optical system (4) that causes light emitted from the light source (3) and not directly incident on the main optical system (2) to be incident on the main optical system (2). An auxiliary light distribution pattern is formed in an external region adjacent to the main light distribution pattern by the light which is incident on the main optical system (2) by means of the auxiliary optical system (4) (lower reflective mirror (41)).
