Light guide plate formed by one-time extrusion moulding and manufacturing process

Abstract

The invention discloses a light guide plate formed by one-time extrusion moulding. The light guide plate comprises a substrate; a concave-point net surface and a concave-line net surface are arranged on the substrate; the concave-point net surface is arranged at the front side of the substrate; and the concave-point net surface and the concave-line net surface are opposite to each other. In addition, the manufacturing process includes: a raw material is extruded into a substrate; optical lattice points are arranged on a roller; and then the substrate is extruded and cut. On the basis of the structure, compared with the existing light guide plate, the provided light guide plate can have the better glowing effect with high uniformity; and thus the light-emitting uniformity of the light guide plate is improved and the lighting effect loss is low. Because the raw material is extruded into the substrate by one time, the processing procedures are reduced; the substrate is dotted by the roller by one-time moulding, so that the procedures are substantially simplified, the manpower cost is lowered, and the processing efficiency is enhanced. Moreover, the optic effect of points and lines of the light guide plate can be optimized and thus the light refraction becomes uniform.

Description

technical field [0001] The invention relates to the field of LED lighting manufacturing, in particular to a one-time extruded light guide plate and a manufacturing process thereof. Background technique [0002] The working principle of the light guide plate is: the light emitted by the lamp stays on the surface of the plate, when the light hits each light guide point, the reflected light will diffuse to various angles, and then destroy the reflection condition and be emitted from the front of the light guide plate; A light guide point of different density and size can make the light guide plate emit light evenly. The light guide plate has high luminous efficiency and low power consumption. However, how to set the density and size of the light guide points on the light guide plate so that the light guide plate can play the greatest role has always been a problem for those skilled in the art to continuously improve. In the prior art, laser dots and hot embossing dots are mai...
