The LED driver functions similar to a fluorescent ballast in that it supplies the proper starting voltage and then regulates the current flowing through the lamp after start up. An LED driver is the power supply for an LED system, much like a ballast is to a fluorescent or HID lighting system. Dimming drivers can dim LED's by reduction in the forward current, pulse width modulation (P W M) via digital control, or more sophisticated methods.
