Description

Technical Field

[0001] The utility model relates to the technical field of automobile lighting equipment, in particular to an ultra-thin dual-light lens module. Background Art

[0002] The headlights of motor vehicles are also called headlamps, which are used to illuminate the road ahead of the vehicle in low visibility or at night. These headlights are mainly used to produce two types of lighting modes, namely, low beam mode and high beam mode. In low beam mode, the light beam has a very obvious light and dark cut-off line, which can provide lighting without interfering with other road participants. In high beam mode, it can illuminate a farther distance in front of the vehicle. These two modes can be switched manually or automatically according to actual conditions.

[0003] However, in the prior art, low beam reflectors and high beam reflectors are usually used to complete the illumination of low beam and high beam, but the low beam reflectors and high beam reflectors are generally arranged in a vertical direction orthogonal to the horizontal emitting direction, which results in a thicker dual light lens module, that is, a larger size in the vertical direction. Therefore, we need to propose an ultra-thin dual light lens module. Utility Model Content

[0011] Preferably, the carrier is arranged in a Z-shape as a whole, and includes a middle portion for separating the low beam assembly and the high beam assembly.

[0012] Preferably, no less than twenty LEDs are arranged on the high beam PCBA light source board, and when all the LEDs are on, it is the high beam function, and when some of the LEDs are off, it is the ADB function.

[0013] Compared with the prior art, the beneficial effects of the utility model are:
