A light guide plate, a flat panel lamp with the light guide plate, and an installation method thereof

Abstract

The invention belongs to the technical field of lamps, and discloses a light guide plate, a panel lamp with the light guide plate and an installation method thereof. The bottom of the light guide plate is provided with a front surface, and the top of the light guide plate is provided with a back surface. A light guide point is arranged at the upper end of the interior, and a reflective layer is fixedly installed on the top of the light guide plate, and a back plate is fixedly installed on the top of the reflective layer. The present invention is provided with a light guide plate, a reflective layer, a back plate, etc. for the purpose of good light guide and astigmatism effects, and the back of the light guide plate is a frosted surface, so that it has dual functions of light guide and diffusion at the same time, and can not only convert the line light source into a surface light source , can make the light more uniform and soft.

Description

technical field [0001] The invention belongs to the technical field of lamps, and in particular relates to a light guide plate, a panel lamp with the light guide plate and an installation method thereof. Background technique [0002] The light guide plate is a high-tech product that converts the line light source into a surface light source. The light guide plate of the prior art uses an optical-grade acrylic (PMMA) plate, and then uses an ink with a very high reflectivity and does not absorb light. The bottom surface of the board is printed with light guide points, and the optical grade acrylic board is used to absorb the light emitted from the lamp to stay on the surface of the optical grade acrylic board. When the light hits each light guide point, the reflected light will diffuse to various angles and then destroy The reflection conditions are emitted from the front of the light guide plate, and the light guide plate can emit light evenly through various light guide poin...

AI Technical Summary

Problems solved by technology

[0003] The light guide plate is generally used with a reflective sheet on the back and a diffuser plate on the front. The purpose of the reflective sheet is to reflect the light exposed on the bottom of the light guide plate back into the light guide plate to improve the use efficiency of light. The purpose of the diffuser plate is to further Diffuse the light to make the light softer. According to the structure and principle of the light guide plate in the prior art, it can be known that the light guide plate in the prior art needs to use high-cost optical-grade acrylic plates and a diffuser plate, so the overall cost is relatively low. high

[0004] In addition, in order to reduce costs and save resources during the installation process, people often only have the structure of the lamp tube corresponding to the position of the light guide plate. At this time, the upper end of the inner side of the lamp frame presents a free area, and the entire structure will appear to be unstable, resulting in The corresponding structure is loose, and at the same time, the internal lamp tube and its corresponding parts lack protection and are prone to damage
