Problems solved by technology

[0004] Most of the existing thick-walled light guide components use flexible PCBs and aluminum substrates as light sources. This solution not only has a high cost per PCB, but also has a complicated installation structure and relatively large installation errors.
Moreover, according to the light distributed by the existing thick-walled light guide components, the uniformity is still insufficient

Abstract

The present invention discloses a light guide component. The light guide component comprises at least one optical unit; the optical unit comprises a front optical surface, a back optical surface, an upper surface and a lower surface; the connection edge of the upper surface and the back optical surface is provided with a coupling incident surface; a light source component is arranged above the coupling incident surface; the back optical surface is a total-reflection surface; the front optical surface is a stepped emergent surface; at least one hollow optical region is arranged in the light guide component; and the hollow optical region includes a first optical surface adjacent to the back optical surface and a second optical surface adjacent to the front optical surface. The invention also discloses an automobile lamp. The automobile lamp comprises a lamp housing as well as a decoration ring, a support component, a power source component, external diffusion glass and the light guide component which are arranged in the lamp housing, wherein the light guide component is fixed between the decoration ring and the support component, and the external diffusion glass is arranged in front of the front optical surface of the light guide component.

Description

technical field [0001] The present invention relates to the field of vehicle lighting, in particular to a light guide component. [0002] The present invention also relates to a vehicle lamp having the light guide member. Background technique [0003] In the field of vehicle lighting, it is a common technical means to combine multiple LED light sources with light guide components to achieve linear structure modeling. Since the LED is a point light source, its energy density decreases from the center to the outside. Even after the reflection and refraction of the secondary light distribution, the light distribution in the adjacent LED area and the light distribution in front of the LED are still different; but the vehicle shape The consistency of lighting effect is demanded, not only from the front view direction of the vehicle, but also from the inside and outside of the vehicle, it still needs to maintain a uniform and tidy linear shape. [0004] Most of the existing thic...
