An LED driver is the power supply for an LED system, much like a ballast is to a fluorescent or HID lighting system, says Al Marble, manager - sales & market development for Philips-Advance Transformer.
A LED driver is an electrical device that regulates the power to an LED or string(s) of LEDs.he power level (or âSpeedâ) of the LED is maintained constant by the driver as the electrical properties change (amount of âgasâ or power needed) throughout the temperature increases and decreases (or âhills and valleysâ) seen by the LED(s).
