The present invention first pushes the stroke extension mechanism to move backward to drive the L-shaped plate to move forward, and the L-shaped plate drives the T-shaped trigger rod to move forward to correspond to the switch on the three-slot switch box that requires output power, and then twists the stroke extension mechanism to reverse, so that the T-shaped trigger rod is reversed to turn one of the switches of the three-slot switch box, and the circuit board is energized to start the LED lamp. In this way, the transmission power can be adjusted according to demand, and the adaptability is strong.

[0004] In the prior art, when the LED switching power supply is running, in order to ensure the stable operation of the LED switching power supply, the LED switching power supply needs to be cooled.

In addition, in the prior art, the heat dissipation channel is protected by a grille, and dust cannot be filtered, so dust easily enters the interior of the LED switching power supply. Therefore, we propose a low-power LED switching power supply. Utility Model Content
