LED panel light structure

Abstract

The invention discloses an LED panel light structure. The LED panel light structure comprises a panel cover. The panel cover is square inside and outside and is chamfered, a heat dissipation rack is connected to the bottom surface of the panel cover, a dam body is defined by the heat dissipation rack along the square bottom surface of the panel cover, a square frame is formed by the inner side faces of the dam body, four rows of LED light bars are arranged along the four side faces forming the square frame, and LED light bead arrays are arranged on the LED light bars, an optical diffusion plate, a refraction plate and a reflection plate are sequentially arranged in the heat dissipation rack defining the dam body from top to bottom, a circle of step groove is formed in the lower edges of the inner side faces of the dam body defined by the heat dissipation rack, an elastic sealing sponge pad is arranged in the step groove, and the lower end of the dam body defined by the heat dissipation rack is covered with a ceramic cover plate. The four rows of LED light bars are connected with an LED protection circuit. According to the LED panel light structure, the lower end face of a heat dissipater is connected with the ceramic cover plate, the heat dissipater conducts heat to the ceramic cover plate, and thus the purpose of rapid heat dissipation is achieved; besides, a dual filter circuit is adopted, and thus LEDs can be effectively protected against damage caused by instant high-voltage breakdown.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to an LED panel light structure. Background technique [0002] LED panel light is a high-end indoor lighting fixture. Its outer frame is made of aluminum alloy through anodic oxidation. The light source is LED. The feeling of beauty. The LED panel light has a unique design. The light passes through the light guide plate with high light transmittance to form a uniform plane luminous effect. The uniformity of illumination is good, the light is soft, comfortable and bright, which can effectively relieve eye fatigue. LED panel lights can also prevent radiation and will not irritate the skin of pregnant women, the elderly, and children. [0003] LED panel lights are widely used, and there is a tendency to replace grille lights; LED panel lights are mainly used in: 1. Ceilings (replacing the original grille lights); 2. Walls (not only for lighting purposes, but also for artistic expression); 3. Ins...

Problems solved by technology

[0004] In the existing technology, the heat dissipation effect of the LED panel light is poor, which directly affects the life of the LED lamp bead. Due to the high voltage requirement of the LED lamp bead during use, if the instantaneous voltage exceeds its load, the LED lamp will burn out
