LED panel light and manufacturing method thereof

Abstract

The invention discloses an LED panel light and a manufacturing method of the LED panel light. Locating blocks and LED light strips are arranged for locating, the locating blocks and corresponding structures on frame sectional material strips carry out close fit locating, therefore, clearances between the side light entering face of a light guide plate and LEDs on the LED light strips are ensured, it is ensured that the center height of the LEDs on the LED light strips and the center height of the side light entering face of the light guide plate are consistent, and the problems that in the prior art, due to the fact that frame sectional materials are directly located and matched through LED light strips, the requirement for processing precision of an LED circuit board (light strips) is high, plugging is difficult, and damage is likely to occur are solved. The four frame sectional material strips are spliced through corner connecting pieces buckled in a multi-point friction contact mode to form a frame, the structure is simple, assembling and debugging are convenient, and the optical effect and consistency of products are ensured. Therefore, according to the LED panel light in the scheme, the light emitting face is even in emitted light, product quality is good, light leakage, light spots and shadows are not prone to being generated, product consistency is good, assembling and debugging are convenient, and the yield and production efficiency are high.

Description

technical field [0001] The invention belongs to the field of lighting fixtures, in particular to an LED panel light and a manufacturing method 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 is covered with a refle...

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
