Background The LED power supply is used as a core component of the lighting equipment, and the working stability and the service life of the LED power supply are directly influenced by the working environment. In outdoor or industrial environments, air is more dust-laden with particles. In order to ensure the heat dissipation efficiency of the LED power supply, it is generally necessary to provide a vent hole in the power supply housing or install a heat dissipation fan, but this design makes external dust easily enter the power supply along with the airflow. When the existing LED power supply is used for treating the contradiction between heat dissipation and dust prevention, a single dust screen is generally adopted to cover the air inlet or the air outlet. However, the structure has obvious defects in actual use that on one hand, the dustproof effect of the single-layer dustproof net is poor, dust passes through the single-layer dustproof net when radiating heat, so that the working efficiency and the service life of an LED power supply are affected, and on the other hand, when part of the power supply stops working, external dust can still slowly infiltrate through an unsealed vent, so that dust accumulation of internal components is caused, and the risk of short circuit or overheating is increased. In addition, the mounting structure of the existing LED power supply is generally simple, and the power supply body easily shakes or even collides in the shell in the transportation or moving process, so that the stability of an internal circuit is influenced.
