Optical collector for automotive dipped headlight module

Abstract

An optical collector for an automotive dipped headlight module comprises an optical collecting structure (1), a cut-off line forming structure (2), a 50L dark region forming structure (3), an III region forming structure (4) and an SEG 10 brightness reducing structure (5). The III region forming structure (4) comprises an III region broadening forming structure (4-1) and an HV brightness reducing structure (4-2); and the cut-off line forming structure (2) is arranged at the front end of the optical collector, the SEG 10 brightness reducing structure (5) is arranged on the bottom of the optical collector, the III region forming structure (4) is arranged on the bottom of the optical collector and is positioned at the front end of the SEG 10 brightness reducing structure (5), and the 50 L dark region forming structure (3) is arranged on the bottom of the optical collector, and is positioned between the III region forming structure (4) and the cut-off line forming structure (2). According to the optical collector for the automotive dipped headlight module, except a lens, all other optical elements and parts of the optical collector are integrated, and therefore, space utilization efficiency is greatly improved; positional accuracy of various optical functional components is guaranteed, and position errors do not exist; and costs are low.

Description

technical field [0001] The invention relates to a vehicle lamp, in particular, the invention relates to a light concentrator for a low beam vehicle lamp module. Background technique [0002] At present, the application of LED light sources in low-beam vehicle light modules has been relatively mature, and there are many types of low-beam vehicle light modules with LED light sources, but the development trend is the miniaturization, simple structure, low cost and high performance of modules. In these aspects, there is still a lot of room for development, and the lamp module with the above characteristics has a good market potential. [0003] In existing car light modules, the concentrator generally only has a single light concentrating structure. In order to form a low-beam light shape that complies with specific regulations (such as ECE R123Class C, V, E, etc.), parts such as visors must also be provided. , the disadvantage of this is that the structure is not simplified eno...

Problems solved by technology

[0003] In existing car light modules, the concentrator generally only has a single light concentrating structure. In order to form a low-beam light shape that complies with specific regulations (such as ECE R123Class C, V, E, etc.), parts such as visors must also be provided. , the disadvantage of this is that the structure is not simplified enough

[0004] In order to meet specific regulations, some existing car light modules need to be equipped with dozens of LED light sources. By controlling the on and off of parts of dozens of LEDs, the brightness of specific areas in the low beam light pattern can be realized. Change, the disadvantage of this is that the cost of the module is high due to the large number of LED light sources, and the module space is large

[0005] Therefore, the current technical problem that needs to be solved in this area is: the existing light module with a concentrator has a low degree of integration. In order to form a cut-off line and reduce the brightness of some areas, it is still necessary to increase the shading plate. Parts are implemented, which makes the structure of the car light module not simple enough, and the volume is not small enough; or to control the brightness change of a specific area in the low beam light shape by turning on and off a large number of LEDs, the cost of doing so is bound to be high, and due to the required The number of LEDs and the number of light-concentrating structures are large, and the volume of the entire module is relatively large
