Abstract
Description
Technical Field
[0001] The utility model relates to the field of light guides, in particular to an integrated light guide bracket. Background Art
[0002] For current light guide products, light is totally reflected and propagated inside a common light guide. At this time, the light is continuously reflected inside the common light guide, but does not emit light on the light-emitting surface 92 of the light guide. Generally, it is necessary to make light guide teeth 91 on the common light guide 9 to destroy its total reflection for lighting, as Figure 1 shown; the light guide is snap-fitted and installed through a bracket as an assembled product. However, during the installation process of the light guide and the light guide bracket 93, situations such as installation deviation or torsion are likely to occur, as Figure 2 shown, resulting in poor irradiation effect and failing to achieve the expected effect.
[0003] Therefore, in combination with the above existing technical problems, it is necessary to provide a new technical solution. Summary of the Utility Model
[0004] In order to solve at least one of the technical problems existing in the prior art, the utility model can provide an integrally connected light guide bracket. No light guide teeth are provided on the light guide, and the light is lit by the contact between the light-emitting surface of the light guide and the reflective ribs on the bracket. There is no need to assemble the light guide and the bracket anymore, avoiding defects such as torsion or improper installation during the installation process or use of the light guide and the bracket. It can effectively reduce the defects of the product caused by installation reasons, and reduce the installation steps and process costs. The specific technical solutions are as follows:
[0005] On the one hand, the utility model provides an integrated light guide bracket, including an integrally connected bracket and light guide;
[0006] The bracket is provided with a light guide contact part, and the light guide contact part is alternately provided with hollow grooves and reflective ribs;
[0007] The light guide includes a light-emitting surface, and the light-emitting surface is in contact with the light guide contact part.
[0008] As a preferred scheme of the integrated light guide bracket of the utility model, the light guide and the bracket are integrally formed by two-color injection molding.
[0009] As a preferred scheme of the integrated light guide bracket of the utility model, the light guide is a light guide made of a light-transmitting material, and the reflective rib is a reflective rib made of an opaque material.
[0010] As a preferred scheme of the integrated light guide bracket of the utility model, along the length direction of the light guide, the hollow grooves and the reflective ribs are alternately arranged in sequence.
[0011] As a preferred embodiment of the integrated light guide bracket of the present utility model, the light guide is a cylindrical light guide column, and a planar light-emitting surface is provided on the surface of the light guide column.
[0012] As a preferred embodiment of the integrated light guide bracket of the present utility model, the light guide is a polygonal column, and the polygonal column includes a regular polygonal column and an irregular polygonal column.
[0013] As a preferred embodiment of the integrated light guide bracket of the present utility model, a light source is further provided at the end of the light guide along the length direction.
[0014] As a preferred embodiment of the integrated light guide bracket of the present utility model, an installation structure is further provided on the bracket, and the installation structure is configured to be able to install the bracket at the position to be installed.
[0015] As a preferred embodiment of the integrated light guide bracket of the present utility model, the bracket is a white bracket.
[0016] As a preferred embodiment of the integrated light guide bracket of the present utility model, the width of the hollow groove is consistent with the width of the light-emitting surface.
[0017] Compared with the prior art, the technical solution of the present utility model has at least one or more of the following beneficial effects:
[0018] Ordinary light guides achieve the lighting effect by making light guide teeth on the surface of the light guide. Through ingenious design, this patent does not provide light guide teeth on the light guide, and the light is lit by the contact between the light-emitting surface of the light guide and the reflective ribs on the bracket.
[0019] At the position where the hollow groove on the bracket corresponds to the light guide, there is no surface contact between the light guide and the bracket at this time, and the light inside the light guide at this position will not shine out; while at the position where the reflective ribs on the bracket correspond to the light guide, the light guide fits with the white reflective ribs of the white bracket. Since the white material will reflect light, the light inside the light guide will be reflected out through the reflective ribs of the white bracket to achieve the lighting effect. In practice, according to the needs of the product, the light emitted by the light guide can also be evenly distributed by controlling the size and density of the hollow groove and the reflective ribs.
[0020] Using a white bracket for light reflection, the white bracket is in the form of diffuse reflection, and the reflected light is more uniform and the effect is better.
[0021] In this patent, the light guide and the bracket are directly injection-molded in the form of two-color injection molding. The light guide is made of a transparent material, and the bracket is made of a white material. The light guide and the bracket are directly injection-molded, and there is no need to assemble the light guide and the bracket again, avoiding defects such as torsion or improper installation during the installation process or use of the light guide and the bracket. It can effectively reduce the defects of the product caused by installation, and reduce the installation steps and process costs.
[0022] Additional aspects and advantages of the present utility model will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present utility model. Description of the Drawings
