The high beam module 100 solves the problems that the reflector is inverted and the radiator is arranged above in the traditional high beam scheme, reduces the size (about 45 mm) of the high beam module 100 in the arrangement direction X, improves the color of the high beam, and obviously improves the optical efficiency and brightness of the high beam.
