Description

Technical Field

[0001] The utility model relates to the technical field of light guides, in particular to a light guide with uniform surface light emission. Background Art

[0002] The light guide plate is made of optical-grade acrylic / PC sheet, and then a high-tech material with extremely high refractive index and non-light-absorbing is used to print light guide points on the bottom of the optical-grade acrylic sheet using laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The optical-grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical-grade acrylic sheet. When the light hits each light guide point, the reflected light will diffuse to all angles, and then destroy the reflection condition and emit from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly. The purpose of the reflective sheet is to reflect the light exposed on the bottom surface back into the light guide plate to improve the efficiency of light use; under the condition of equal area luminous brightness, the luminous efficiency is high and the power consumption is low. The single-sided microstructure array light guide plate generally adopts the extrusion molding production process, but it still has the following disadvantages in actual use:

[0003] At present, the existing light guide with uniform surface light emission has poor flame retardant performance when in use, and has poor applicability in places with high fire protection requirements, and has certain limitations in use; or the existing light guide with uniform surface light emission has weak mechanical strength when in use and is easily damaged, thereby causing certain economic losses, and has certain limitations in use.
