Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a novel high-power LED panel light with high efficiency, high reliability and convenient maintenance. Background technique [0002] Due to high light efficiency, long life, low working temperature, non-toxic and non-electromagnetic pollution, LED has the characteristics of green and environmental protection, and is recognized as the fourth-generation lighting source. Due to the small light-emitting area of ​​LEDs, large luminous flux, and concentrated light energy, the glare is severe when directly used for indoor lighting. Therefore, when LEDs are used in the field of indoor lighting, it is usually necessary to install diffusing materials on the surface of lamps to disperse the light energy of LEDs. [0003] The light efficiency and reliability of LED lamps are affected by various factors such as heat dissipation conditions, lamp bead arrangement, power drive efficiency, cost, etc. C...

AI Technical Summary

Problems solved by technology

[0003] The light efficiency and reliability of LED lamps are affected by various factors such as heat dissipation conditions, lamp bead arrangement, power drive efficiency, cost, etc. Currently, most LED panel lights on the market adopt a dense arrangement of low-power LEDs, although the surface of the panel light The brightness is uniform, and it has a price advantage compared to high-power LED panel lights. However, comparing the two types of lamps, low-power LED panel lights have three main shortcomings: 1. Low-power LED panel lights usually need hundreds to thousands of high-power LED lights bead, resulting in complex circuit structure and reduced reliability of lamps

2. Due to the defects of low-power LED chips and packaging structures, the overall light decay time of low-power LEDs is relatively fast, and the long-life characteristics of LEDs are not obvious.

3. For places with high illumination requirements (such as subways and shopping malls), it is difficult for low-power LED panel lights to meet the lighting requirements

Most of the existing high-power LED panel lights use light guide plate and backlight technology. Compared with traditional lamps, the output light efficiency of this lamp has no significant advantage

At the same time, because the indoor panel lamps have high requirements on the uniformity of the entire light-emitting surface, the high-power LED panel lamp adopts the side-emitting method, and the high-power LED lamp beads are located on the side of the lamp, and the bright spots are obvious. If the frame is widened to eliminate bright spots, will result in inefficient lamps
