[0002] LED driver power supply is a power converter that converts power supply into a specific voltage and current to drive LED to emit light. Usually, the input of LED driver power supply includes high-voltage power frequency AC (i.e. mains), low-voltage DC, high-voltage DC, low-voltage high-frequency AC (such as the output of electronic transformer), etc., while the output of LED driver power supply is mostly a constant current source that can change the voltage as the forward voltage drop value of the LED changes.

[0003] According to the announcement number: CN218473435U, a dimming-controlled LED driver power supply is disclosed, including an LED driver power supply body, circuits are provided at both ends of the LED driver power supply body, an upper dust shielding plate is installed at the upper end of the LED driver power supply body, a first inner scraper is installed horizontally and slidably inside the upper dust shielding plate, the lower end of the first inner scraper is fitted with the upper end of the LED driver power supply body, and the upper end of the first inner scraper is fitted with the lower end of the upper dust shielding plate. The utility model can play an auxiliary heat dissipation effect through multiple heat sinks, and can improve the overall heat dissipation capacity of the LED driver power supply body. At the same time, after long-term use, the user can pull the connecting rod left and right, and the movement of the connecting rod drives the movement of multiple second inner scrapers. The movement of multiple second inner scrapers can clean the surface of multiple heat sinks, which can effectively maintain the heat dissipation performance of the heat sink and avoid the situation where the user has difficulty in cleaning the heat sink;
