How does a LED power supply work?
How does a LED power supply work? LED drivers provide an interface between the power supply (line) and the LED (load), converting the incoming 50 Hz or 60 Hz AC line power at voltages such as 120 Volts, 220 Volts, 240 Volts, 277 Volts or 480 Volts to the regulated DC output current.
What is the voltage of LED bulb?
Typically, the forward voltage of an LED is between 1.8 and 3.3 volts. It varies by the color of the LED. A red LED typically drops around 1.7 to 2.0 volts, but since both voltage drop and light frequency increase with band gap, a blue LED may drop around 3 to 3.3 volts.
How do you wire a LED transformer?
- Check the LEDs are in place and turn off the power.
- Open the driver or transformer using a screwdriver.
- Connect the plug using suitable cabling and wire nuts (colour-coded cabling screws).
- Apply terminal connectors to the cabling for a firm hold.
How do dimmable LED drivers work?
HOW A DIMMING DRIVER WORKS. A dimming driver has two functions: As a driver, it converts the 230V AC mains input to a low voltage DC output. As a dimmer, it reduces the amount of electrical energy flowing to the LEDs, thereby causing them to dim.
