Technical Field
[0001] The utility model relates to the technical field of lighting, and more specifically, to a light guide and an ADB (Adaptive Driving Beam) module. Background Art
[0002] High beam is one of the most important functions of a car. It is commonly known as "headlight" in contrast to low beam. Compared with low beam, high beam emits light in parallel, is concentrated and has a higher brightness, can illuminate higher and farther objects, and is very helpful for the driver's vision at night. However, the phenomenon of abuse of high beam is quite serious at present. Abuse of high beam may blind the other driver instantly, greatly increasing the probability of traffic accidents.
[0003] With the development of automobile lighting technology, adaptive high beam lights have emerged. With the cooperation of the vehicle's front camera, they can automatically control the brightness of the high beam, while ensuring the driver's clear vision, forming a dark area in the area where there are vehicles, so as not to dazzle the drivers of other vehicles on the road. Although adaptive high beam lights have many advantages, the performance of existing adaptive high beam lights still needs to be improved. Utility Model Content
