[0002] LED flat panel lights are products developed based on traditional flat panel lights using new LED lighting sources. Compared with traditional flat panel lights, they have the following advantages: energy saving, low carbon, long life, good color rendering, and fast response speed. LED flat panel lights are mainly used in hotels, conference rooms, factories or offices, commercial purposes, residences or public facilities, schools, hospitals, etc. The structure in which the power supply is installed in the lamp is particularly important, because the luminous efficiency of LED decreases as the temperature of LED increases, so the heat dissipation of LED is very important.

[0003] Existing LED lamps usually use a combination of fans and heat dissipation holes to dissipate heat. This method easily accumulates dust at the fans and heat dissipation holes, affecting the heat dissipation effect. At the same time, the lamp box structure is relatively closed. When the staff needs to maintain or replace the lamp tube, it usually takes a lot of time to load and unload it, and the process is relatively inconvenient. Utility Model Content
