LED power supply
The LED power supply is to convert the power supply to a specific voltage current to drive the LED's luminous voltage converter.
Generally, the input of LED power supply includes high-voltage power frequency communication (i.e., city power), low voltage dc, high voltage dc, low voltage high frequency ac (such as the output of electronic transformer) etc.The output of LED power supply is the constant current source that can change the voltage with the change of the positive pressure drop of the LED.
The core components of the LED power supply include switch controllers, inductors, switch components (MOSfet), feedback resistance, input filter parts, output filters, etc.According to the requirements on different occasions, the circuit of over-voltage protection circuit, input voltage protection circuit, LED open circuit protection and overcurrent protection circuit are required.
