[0002] Panel lights are high-end indoor lighting fixtures, with an outer frame made of anodized aluminum alloy and LED light sources. Because they are flat in shape, the light is output in a completely flat plane and has a wider luminous angle, and are widely used in hotels, conference rooms, factories or offices, commercial purposes, residences or public facilities, schools, hospitals, and other places that require energy-saving and high color rendering index lighting. With the continuous development of LED technology, LED panel lights have also developed rapidly and quickly become a hot product in the lighting market, becoming the best product to replace traditional grille light panels in the LED era.

[0003] At present, back-lit LED panel lights have gradually replaced traditional lamp panels due to their advantages such as low cost and stable performance, but they still have the following defects: in order to prevent users from visually seeing the light point, a certain distance is set between the light source and the diffusion plate of the back-lit panel light, but this leads to an increase in the thickness of the lamp, and the cost of the lamp housing and packaging also increases accordingly; in addition, the increase in thickness also increases the transmission path of light, which reduces the energy efficiency of the lamp.
