Document Type and Number:
WIPO Patent Application WO/2019/196156
Kind Code:
A1
Abstract:
Disclosed are a light-guide-based high and low beam system and a vehicle lamp, which belong to the technical field of vehicle lamp illumination systems. The high and low beam system comprises a collimating light-transmitting device (2) and a light guide (3). The collimating light-transmitting device (2) and the light guide (3) are successively arranged in the direction of light beams (4) emitted by light sources (1), and a light-emergent face of the light guide (3) is convex, so that the light beams (4) emitted by at least one light source (1) successively pass through the collimating light-transmitting device (2) and the light guide (3) and are emitted to form a light spot (7) with parallel upper and lower light beams (4) and diffused left and right light beams (4). One of a low beam broad light type, a low beam inflection point light type and a high beam light type is realized by means of the combination of different light sources (1), and multiple functions such as AFS and ADB can be further realized.
