LED The lamp power supply adopts the constant current drive mode, that is, the output current is constant, and the output voltage changes with the load change. In the case of measurement, the measured voltage value is the 310V DC voltage after AC 220V rectification.Continue reading LED Constant Current Power Supply Circuit Diagram
The LED driver changes the power supply to a specific voltage and current to drive the LED voltage converter. The output of LED driver power supply is mostly constant current source, which can change the voltage with the change of led forward voltage drop. The core components of LED power supply include switch controller, inductor, MOSFET, feedback resistor, input filter device, output filter, etcContinue reading What is a LED Driver Used For?
