Document Type and Number:
WIPO Patent Application WO/2018/133250
Kind Code:
A1
Abstract:
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 portion or right portion of the condenser (1), and the number of high-beam LED light sources (2) is at least two. An LED light source corresponding to a rear end of the block cavity structure (7) 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 (7) and is then emitted forwards, so as to form a part of a high-beam light shape. The LED light source corresponding to the rear end of the block cavity structure (7) on the condenser (1) is in an off state when being in an ADB working state, the other LED light sources are lit up, and light is fully reflected and is then emitted forwards when being irradiated on a side face (7-2) of the block cavity structure (7), so as to form an ADB light shape.
