Abstract
Disclosed is an LED light source high-beam and low-beam integrated automobile lamp module with an ADB function, comprising a condenser (1), high-beam LED light sources (2), a low-beam LED light source (3), an auxiliary reflector (4), a reflector (5) and a lens (6). A block cavity structure (7) is arranged in the middle of a left or right portion of the condenser (1), and the number of the high-beam LED light sources (2) is at least two. An LED light source corresponding to a rear end of the block cavity structure on the condenser (1) is in a lit-up state when being in a full-high-beam working state, and light emitted thereby is transmitted by the block cavity structure and then is emitted forwards, so as to form a part of a high-beam light shape.
