LED (light emitting diode) panel lamp and frame thereof

Abstract

The invention discloses an LED (light emitting diode) panel lamp and a frame thereof. The frame is spliced by two first frame section bars and two second frame section bars through four corner joints; the two second frame section bars are arranged oppositely, each corner joint is provided with a first plugging arm and a second plugging arm; the root part of each first plugging arm is connected with the corresponding second plugging arm, the head part of each first plugging arm is inserted into a first jack of the corresponding first frame sections bar, the top of each first plugging arm and the top inner wall of the corresponding first jack are provided with at least three contacts which are not in the same line, and the bottom of each first plugging arm and the bottom inner wall of the corresponding first jack are provided with at least three contacts which are not in the same line; the head part of each second plugging arm is inserted into a second jack of the corresponding second section bar, and is connected with the same method; the root part of each first plugging arm is larger than the head part of the first plugging arm, and the root part of each second plugging arm is larger than the head part of the second plugging arm. The LED panel lamp and the frame thereof adopting the technical scheme have the advantages that the structure is simple and reasonable, 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, in particular to an LED panel light and its frame. 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 reflective layer. The non...

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
