A light guide structure for an automobile electronic product

Abstract

The invention discloses a light guide structure for an automobile electronic product. The structure comprises a light guide strip (1), a light guide strip mask (2), screws (3), an LED module (4) and adecorative frame (5). The two sides of the light guide strip (1) and the LED module (4) are fixed on the decorative frame (5) through screws (3), and the light guide structure is characterized in that the light guide strip mask (2) is clamped on the decorative frame (5) through buckles (6) to press the light guide strip (1), so that the light guide strip does not shake, and a light guide column is also provided with mounting holes and limiting holes for limiting connection with other parts. According to the invention, the light guide strip and the decorative strip form the light guide structure of the automobile electronic product, so that a light diffusion sheet is omitted, the purchase cost is reduced, and the assembly process is simplified.

Description

technical field [0001] The invention belongs to the field of automobile lighting, in particular to a light guide structure used in automobile electronic products. Background technique [0002] In the field of automotive electronics, decorative light guide mechanisms are more and more widely used in audio panels of mid-to-high-end cars. In the prior art, the light guide mechanism is to add serrations or bumps on the light guide to control the propagation route of the light, and then transmit the light from the light guide to the parts on the exterior surface through the astigmatism sheet to achieve decorative lighting effects . The assembly, manufacture and installation of parts are more complicated. At the same time, in order to meet the uniformity of light, the elongated light guide structure usually requires multiple LED light sources, resulting in an increase in LED procurement costs, and the sawtooth or bump shape of the light guide has relatively high requirements for...
