Description

technical field

[0001] The invention relates to the technical field of LED lamp driving power supply, in particular to an LED lamp driving power supply. Background technique

[0002] The LED lamp is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and the circuit board with silver or gold wires, and sealed with epoxy resin around it to protect the inner core wire. Function, the shell is finally installed, so the shock resistance of the LED lamp is good.

[0003] Under normal circumstances: the input of the LED drive power supply includes high-voltage power frequency AC (that is, mains), low-voltage DC, high-voltage DC, low-voltage high-frequency AC (such as the output of an electronic transformer), etc. The output of the LED drive power supply is mostly a DC current source that can change the voltage with the change of the LED forward voltage drop.

[0004] The LED light driving ...
