Why does the LED drive need to be filled?

LED driver filling is beneficial for thermal conductivity and waterproofing: (1) Through glue filling, the heat of the component can be exported and dissipated through the shell, so that the internal temperature is uniform and the overall temperature is reduced. (2) The inside of the driver is filled by glue, and the infiltration of water molecules is reduced and the waterproof performance is improved through the cooperation with structural parts such as the shell, so as to improve the outdoor adaptability of the LED driver.
