[0002] Panel lights can be divided into direct-light panel lights and side-light panel lights. Side-light panel lights mainly use light guide plate technology. The light guide plate grid is designed according to the arrangement of the LED lamp beads and the emitting angle of the lamp beads, so that the light can pass through the light guide plate to achieve the effect of uniform brightness. Direct-light panel lights use high-brightness LEDs as the light source and adopt direct-light distribution design. They have the characteristics of high luminous efficiency, uniform light output, safety and reliability, low power consumption and long life. However, the existing direct-light panel lights still have certain problems when used. For example, they need to use external lifting devices or use bolts to install them in a designated position during installation, which makes it inconvenient to quickly disassemble and maintain them. In addition, the existing direct-light panel lights only use aluminum frames for heat dissipation, and the heat dissipation efficiency is low, which makes it impossible to dissipate heat in time, thereby reducing the service life.
