Embodiment Construction

[0011] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0012] Such as figure 1 and 2 As shown, this embodiment provides a light guide strip for automobile lighting, which includes a light guide body 1, the left end of the light guide body 1 is the light incident end, and the left part of the light guide body 1 is tilted upward; A light source 2 is arranged on the side; flute-like patterns 3 arranged evenly and equidistantly are distributed on the front surface of the middle part of the tilted part of the left part of the light guide body 1; Prism 4. The pitch of the flute-shaped patterns 3 arranged at equal intervals is 0.5mm. The flute-shaped pattern 3 corresponds to the front and back of the reflective prism 4 and the flute-shaped patter...

Abstract

The object of the present invention is to provide an automotive lamplight guiding strip including a light guide body. The left end of the light guide body is a light incident end. The left part of the light guide body is upwardly warped. A light source is disposed on a left side of the light incident end of the light guide body. Flute-shaped patterns arranged uniformly at equal intervals are distributed on the front surface of the center of the left wrapped part of the light guide body. A reflection prism is disposed on the rear surface of the left wrapped part of the light guide body. The light source provides necessary radiation light for the system. A light beam is spread and scattered along the light guide body and the reflection prism at the rear surface of the light guide body. When passing through a flute-shaped structure, the light beam is further scattered and modulated so that the overall brightness of the light guide is more uniform and full, and the uniformity of light emission is improved.

Description

technical field [0001] The invention relates to the field of automobile lights, in particular to a light guide strip for automobile lights. Background technique [0002] The optical system includes a light source, a light guide system, and a receiver. In general, common light guiding systems are mirrors and light guides. For the light guide, the light emitted by the light source is guided to the light emitting surface of the light guide, and then the light source module forms a surface light source. However, since each part of the light guide does not emit light uniformly, the scattered light is not beautiful, and the brightness is uneven and not full. With the development of automotive lighting technology, more requirements are put forward for the lighting performance of automotive lamps, including the uniformity and consistency of the overall brightness of the light guide. Therefore, how to solve the problem of the overall brightness uniformity of the automobile light g...
