LED light source far and near light integrated automobile lamp module with ADB function

Abstract

The invention relates to an LED light source far and near light integrated automobile lamp module with an ADB function. The module comprises a condenser (1), far light LED light sources (2), near light LED light sources (3), an auxiliary reflector (4), a reflector (5) and a lens (6). A blocky cavity structure (7) is formed in the middle of the left portion or right portion of the condenser (1), and the number of the far light LED light sources (2) is at least two. The LED light sources corresponding to the rear end of the blocky cavity structure on the condenser (1) are turned on in a full far light working state, emitted light is transmitted by the blocky cavity structure and then emitted out forwards to form part of a far light shape, the LED light sources corresponding to the rear end of the blocky cavity structure on the condenser (1) are turned off in an ADB working state, other LED light sources are turned on, light is fully reflected and emitted out forwards when irradiated on the side face (7-2) of the blocky cavity structure, and an ADB light shape is formed.

Description

technical field [0001] The present invention relates to a car lamp, in particular, the present invention relates to a car lamp module with an LED light source integrating far and near beams with an ADB function. Background technique [0002] With the continuous development of the application of LED light sources in car lights, far and low beam car light modules with various performances emerge in an endless stream. As one of the development directions, the integration of far and low beam car light modules and their low cost and volume Compact, simple in structure and complete in function, it is very popular in the market. [0003] Driving safety has been paid more and more attention by people. There are many driving accidents caused by improper use of high beam every year. The lamp module with ADB function can solve the contradiction between the use of high beam and low beam to a certain extent, which not only makes the car have a good visibility, and prevent other vehicle ...

AI Technical Summary

Problems solved by technology

[0004] Existing car light modules with ADB function are mainly divided into three categories, one is to form an ADB light shape by shielding the light with a visor, this form of module needs to be equipped with visors, solenoid valves and other parts The structure is relatively complex, and the volume is large, and the cost is high; the other type is to form an ADB light shape by turning off some LEDs in the high-resolution LED matrix. This type of module requires a large number of LED light sources, and the cost is high. And because it generally needs to have a visor part, the volume is also limited to a certain extent, and the structure is still complicated; the third type is in the form of a matrix of reflective surfaces, each reflective surface corresponds to an LED light source, and each reflective surface corresponds to a LED light source. A part of the light shape is superimposed and combined by different parts of the light shape to form an ADB light shape. Due to the limitation of the reflective surface structure, this form of module is also large in size and complex in structure.

[0005] Therefore, the current problems are that the existing ADB function lamp module has high cost, complex structure, small size, low integration degree and insufficient functions.
