Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp lighting modules, and specifically but not limited to a low beam zone III lighting module and a dual light lens module. Background Art

[0002] For the automotive headlight LED module, the conventional structure includes a heat sink, a light source, a main optical mechanism, a light baffle, a lens bracket and a lens. The high and low beam integrated LED module requires an additional solenoid valve or a motor to flip the light baffle.

[0003] As car lights become smaller and more efficient, LED light source car light modules are becoming increasingly popular. Existing LED modules have increasingly higher requirements for structure and cost control, and existing conventional LED modules are gradually unable to meet the requirements.

[0004] The low beam of a car headlight is for close-range lighting. According to the relevant standards for car lights (taking the Chinese standard gb25991 as an example), the low beam light shape has an important component called "Zone III", which is located above the cut-off line and mainly serves to illuminate objects above the road surface, such as signs, so that the driver can obtain information such as signs.

[0005] For automotive headlight LED modules, such as Figure 1-Figure 3 As shown, the conventional III zone approach is to make a special structure on the light-emitting surface of the lens, such as a pattern, an arc-shaped incision, etc., to form the low beam III zone light 1, but this solution will destroy the integrity of the lens and affect the overall appearance of the module. At the same time, the high and low beam PCBs of the module are connected by a connecting harness, which makes the assembly complicated.

[0006] In view of this, it is necessary to provide a new structure to solve at least part of the above problems. Utility Model Content

[0007] In response to one or more problems in the prior art, the utility model proposes a low beam zone III lighting module and a dual-beam lens module, wherein low beam zone III light is formed by arranging a low beam zone III reflection structure inside the module, and the low beam zone III reflection structure is designed as a plurality of reflective bowl structures, thereby meeting the appearance requirements of the lens and ensuring product consistency. FPC soft board is used for electrical connection between the high and low beam PCBs, which saves connecting wiring harnesses and makes assembly more convenient.

[0008] The technical solution to achieve the purpose of this utility model is:

[0009] A low beam zone III lighting module, comprising:

[0010] A low beam lighting unit, arranged at the rear side of the lens, for forming a low beam light distribution;

[0014] Furthermore, in the low beam zone III lighting module of the utility model, the low beam zone III reflective structure includes a plurality of laterally arranged reflective bowls.

[0015] Furthermore, in the low beam zone III lighting module of the utility model, the reflective bowl is a 3mm*3mm diamond-shaped concave surface.

[0017] Furthermore, in the low beam zone III lighting module of the utility model, the low beam lighting unit includes a low beam light-emitting element and a low beam reflecting element. The low beam light-emitting element is arranged in the reflecting area of ​​the low beam reflecting element. The low beam reflecting element is used to reflect the light emitted by the low beam light-emitting element and form a low beam light distribution.

[0018] A dual light lens module, comprising:

[0019] A lens assembly is used for outwardly projecting a high-beam and a low-beam light pattern, the lens assembly comprising a lens bracket and a lens mounted on the lens bracket, the lens being arranged vertically;

[0020] A light-shaped baffle is disposed laterally behind the lens, with one end thereof corresponding to the middle of the lens;

[0021] A low beam assembly, arranged on the upper rear side of the light-shaping baffle, for forming a low beam light distribution;

[0022] A high beam assembly, arranged at the rear lower side of the light-shaped baffle, for forming a high beam light distribution;

[0023] The low beam zone III reflective structure is arranged on part of the light path of the low beam light distribution. The low beam zone III reflective structure is located at the top of the high beam assembly and is integrally formed with the high beam assembly, and corresponds to the other end of the light-shaped baffle and leaves a gap, so as to form the low beam zone III light distribution.

[0024] Furthermore, in the dual-light lens module of the utility model, the low-light assembly includes a low-light PCB, the high-light assembly includes a high-light PCB, and the low-light PCB and the high-light PCB are connected via an FPC soft board.

[0025] Furthermore, in the dual-light lens module of the utility model, the low beam zone III reflection structure includes a plurality of laterally arranged reflective bowls.

[0026] Furthermore, in the dual-light lens module of the utility model, the reflective bowl is a 3mm*3mm diamond-shaped concave surface.

[0028] 1.

[0029] 2. The dual-light lens module of the utility model has a compact structure and a reasonable design. The low-beam zone III light shape is formed by integrally forming a low-beam zone III reflective structure on the high-beam component, and a horizontal light-shaped baffle is added between the low-beam zone III reflective structure and the lens. The transmission of the low-beam zone III light is achieved by utilizing the gap between the light-shaped baffle and the low-beam zone III reflective structure. There is no need to add patterns or other structures to the lens, thus meeting the requirements for the appearance of the lens. By using an FPC soft board to connect the low-beam PCB and the high-beam PCB, the connection harness between the high-beam and low-beam PCBs is saved, making assembly more convenient.
