LED panel lamp and lamp bar installation structure thereof

Abstract

The invention belongs to the field of lighting lamps and particularly relates to a detachable LED panel lamp and a lamp bar installation structure thereof. The lamp bar installation structure comprises a frame, an LED lamp bar, positioning blocks and a light guide plate assembly, wherein the frame is formed by connection of two first frame profile bars and two second frame profile bars through four corner connection pieces, first profile bar cover plates are mounted on the first frame profile bars in a detachable connection manner, the middles of the first profile bar cover plates extend downwards to form positioning bars, the cross sections of the positioning bars of the first profile bar cover plates are in L shapes, the tail ends of the L shapes are folded to form second limit flanges, first limit flanges are further arranged in the positions, corresponding to the second limit flanges, of the first profile bar cover plates, the positioning bars of the first profile bar cover plates, the first limit flanges and the second limit flanges form an accommodating space, and the LED lamp bar is located in the accommodating space. The LED lamp bar is easy and convenient to replace and is time-saving and labor-saving.

Description

technical field [0001] The invention belongs to the field of lighting fixtures, in particular to a detachable LED panel light and a light bar installation structure thereof. 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 i...

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
