Description

technical field

[0001] The invention is an over-temperature protection LED drive power supply, which belongs to the technical field of lighting. Background technique

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

[0003] In the prior art, there are still many deficiencies in the LED drive power supply. During the heat dissipation process, the dust and moisture in the air cannot be filtered, causing the dust and moisture to enter the power supply, resulting in short circu...
