LED panel lamp and positioning blocks

Abstract

The invention belongs to the field of lighting lamps and particularly relates to a detachable LED panel lamp and positioning blocks of the LED panel lamp. Each positioning block comprises a positioning plate, a side plate, an upper panel and a lower panel, wherein the positioning plate is mounted between an LED lamp bar and an incident light side of a light guide plate assembly, the side plate is mounted on a non-incident light side of the light guide plate assembly, the upper end and the lower end of the positioning plate are fixed with the upper panel and the lower panel respectively, the upper end and the lower end of the side plate are fixed with the upper panel and the lower panel respectively, and a clamping space is formed among the positioning plate, the side plate, the upper panel and the lower panel. According to the structures of the positioning blocks, the positioning blocks abut against the LED lamp bar, the integral structure of the LED lamp bar is not damaged, and the structural strength of the LED lamp bar is improved; a limit relationship exists between the positioning blocks and a profile, so that the position between a back light plate assembly and the LED lamp bar is more accurate and stable, the emergent light of a light-emitting surface of the LED panel lamp is ensured to be uniform, and the product quality is good.

Description

technical field [0001] The invention belongs to the field of lighting fixtures, in particular to a detachable LED panel light and its positioning block. Background technique [0002] Light-emitting diodes, as light-emitting devices, are more and more widely used in the field of lighting fixtures. LED has the advantages of low power consumption, high luminous intensity, energy saving and environmental protection. Compared with traditional lamps such as incandescent lamps and fluorescent lamps, LEDs are more and more preferred by users. In the field of home lighting, LED ceiling lamps have become more and more popular. [0003] In the prior art, the LED panel light using the light guide plate is provided with textures on one side of the light guide plate, such as silk screen texture, frosted texture or concave-convex texture, and a reflective layer is covered on the textured surface of the light guide plate, and then the surface of the light guide plate is covered with a refl...

AI Technical Summary

Problems solved by technology

The patented structure realizes the positioning of the LED light bar and the light guide plate assembly by setting a positioning block on the LED light bar. The positioning holes set on the LED light bar affect the overall strength of the LED light bar, and the LED light bar of the LED panel light and The light guide plate assembly will produce some tight fit during installation, and the installation is difficult. After the assembly is completed, when replacing and maintaining the LED light bar, the entire frame needs to be disassembled, which is extremely inconvenient
