Light guide assembly and display lamp set

Abstract

The invention discloses a light guide assembly comprising a base which is provided with a first mounting surface and a second mounting surface which are perpendicular to each other; a plurality of light guide columns are provided, wherein each light guide column comprises a light incoming surface and a light outgoing surface in different directions to form a light conduction path of a corner for changing the light direction, the light incoming surface extends over the first mounting surface, and the light outgoing surface extends over the second mounting surface; the first mounting surface andthe second mounting surface are arranged between the light guide columns and are provided with cut-off openings, and the base and the plurality of light guide columns are formed in a single injectionmolding mode. Through single injection molding of the light guide assembly, the assembly cost of raw materials and the light guide assembly can be reduced, the cost of a product is effectively reduced, and the competitiveness of the product is improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a light guide assembly and a display lamp group. Background technique [0002] Electronic devices such as routers, mobile phones, tablets, and computers all include display light groups, and the display light groups include light guide columns. The light guide column is a device that transmits from a light source to another point at a certain distance from the light source with minimal loss. The light source device provided with the light guide column injects the light source into the light guide column, so that the light is totally reflected or refracted inside the light guide column, so that the light can be irradiated outward from the light exit surface of the light guide column to a predetermined position. [0003] Most of the existing light guide columns are vertical towers. When the direction of incoming light and the direction of light out are not in the same dir...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing light guide columns are in the shape of a vertical tower. When the light incident direction and the light output direction are not in the same direction, light leakage and string light are prone to occur during the light guide process, resulting in poor effect of the LED (light emitting diode) display light on the outside. Good, the current technology is to design a light guide column with 90° refraction of light. This design uses double light guide columns and multiple hot-melt processes to join the two light guide columns. At the same time, two layers of light-shielding foam are required, and one of The light column adopts a two-shot molding process, so the assembly operation of this design is complicated, resulting in low production efficiency, and high material costs, which in turn lead to high costs
