led light bar installation structure and led panel light

Abstract

The invention discloses an LED (light emitting diode) lamp bar mounting structure and an LED panel lamp. A positioning block and the LED lamp bar are arranged to play a positioning effect, and then the positioning block and a corresponding structure of a frame section bar are positioned in a close fit manner, so that the gap between the side incoming surface of a light guide plate and LEDs on the LED lamp bar is ensured, and the central height of the LEDs on the LED lamp bar is consistent with the central height of the side incoming surface of the light guide plate, besides, the problems that an LED circuit board (lamp bar) requires high processing precision, and the LED circuit board is difficult in plugging and easily broken in the prior art depending on the direct positioning and matching of the LED lamp bar and the frame section bar are solved. Therefore, the LED panel lamp adopting the technical scheme has the advantages that the light emitted from the light emitting surface is uniform, the product quality is high, light leak, light spot and shadow cannot be caused easily, the product consistency is good, the assembly and debugging are convenient, the yield is high, and the productivity is high.

Description

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

AI Technical Summary

Problems solved by technology

In the above structure, the LED circuit board (light bar) can only be inserted from the frame groove at one end of the frame profile to the other end, which is difficult to insert and install, and a large assembly gap must be left, otherwise it will cause failure to assemble or damage the light bar , a large assembly gap will lead to large differences in luminous effects and quality problems, and it is also impossible to ensure the gap between the light incident surface on the side of the light guide plate and the LEDs on the LED light bar, nor can it ensure the center height of the LEDs on the LED light bar Consistent with the center height of the side incident light surface of the light guide plate
