Description

Technical Field

[0001] This utility model belongs to the technical field of automotive light guide strips, specifically relating to a dual-color light guide strip for automotive lights. Background Technology

[0002] With the rapid iteration of automotive lighting technology, while ensuring that the lights strictly comply with national and industry regulations on core performance requirements such as light pattern and brightness, the focus on the appearance refinement and lighting visual effect of the lights continues to increase. In order to enhance the overall technological feel of the vehicle, the automotive signal light field is gradually adopting light guide strips as the core light-emitting component, which can achieve a thinner and more uniform light-emitting effect, and better fit the current design trend of automotive lights.

[0003] However, existing light guides have the following problems: On the one hand, existing light guides rely on dedicated brackets for fixed installation, and the brackets cover the internal circuits, interfaces and other structures to ensure a neat appearance. However, the design and development of brackets and the making of molds will generate additional costs, and the production, storage and assembly of brackets will increase the complexity of material turnover management, which will directly lead to an increase in the production cost of the whole lamp. On the other hand, existing light guides often have problems such as light leakage from non-designed areas or exposed internal brackets and circuits due to insufficient precision in the fit between the bracket and the light guide and unreasonable design of the light source incident path. This makes it difficult to meet the dual requirements of appearance integrity and lighting effect stability at the same time. Therefore, we propose a dual-color light guide strip for automotive headlights. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-color light guide strip for automotive headlights to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-color light guide strip for automotive headlights, comprising: A dual-color light guide strip body, wherein the dual-color light guide strip body is installed at the mounting position of the automotive headlight; The lighting circuit board module is provided in two parts, and the two lighting circuit board modules are respectively disposed at both ends of the dual-color light guide strip body; The dual-color light guide strip body is integrally molded and has a dual-color structure, which includes a black shielding plate for fixing and a transparent strip for guiding light.

[0006] Preferably, the lighting circuit board module includes a circuit board and a lighting lamp; The circuit board is disposed at one end of the transparent strip, and the lighting lamp is disposed on the circuit board.

[0007] Preferably, the illumination direction of the lighting lamp is aligned with the transparent strip.

[0008] Preferably, the circuit board and the transparent strip are fixed by heat riveting or screws.

[0009] Preferably, the material of the circuit board is selected as a resin board or an aluminum substrate according to the actual power of the car headlights.

[0010] Preferably, the black shield is fixed to the vehicle headlight mounting position by hot riveting or screws.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model adopts an integrally molded dual-color light guide strip body. The black shield plate replaces the light guide strip bracket, which on the one hand fixes the dual-color light guide strip body in the installation position of the car headlight, and on the other hand shields the internal circuits, interfaces and other structures to avoid appearance defects. By replacing the traditional light guide strip bracket with the black shield plate, the design and development costs of the bracket, mold costs and material turnover management costs are saved. At the same time, the assembly process of the whole lamp is reduced, and the total production cost is reduced. The transparent strip is the core area of ​​the light guide, which is used to conduct light and achieve uniform light emission. Lighting circuit board modules are installed at both ends of the transparent strip, and the illumination direction of the lighting lamp is aligned with the transparent strip to ensure that the light source is accurately incident from both ends of the transparent strip. With the shielding effect of the black shield plate, the light can be completely blocked from escaping from non-designed areas, and the internal circuits and interfaces are not exposed, so as to balance the uniformity of lighting and the integrity of the appearance.
