  • How does an LED driver differ from a convectional power supply? An LED driver is a self contained power supply which regulates the power required for an LED or array of LEDs. The light emitting diodes are low energy, lighting devices with a long lifespan and low energy consumption, hence the requirement for specialized power supplies.
    • LEDs begin to produce light once their supply voltage is equal to or greater than the diode's forward voltage drop (typically in the region of V). The current required for full brightness varies from device to device but is typically mA for a 1W LED (usually the smallest size used in lighting applications).
