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.
An LED driver is a self-contained power supply that has outputs matched to the electrical characteristics of your LED or array of LEDs.There are currently no industry standards, so understanding the electrical characteristics of your LED or array is critical in selecting or designing a driver circuit.Drivers should be current-regulated (deliver a consistent current over a range of load voltages).here are currently no industry standards, so understanding the electrical characteristics of your LED or array is critical in selecting or designing a driver circuit.
