What is an LED Driver?

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.

Do we need an LED Driver?

Due to increasing energy regulations, most people are familiar by now with the long life spans and energy savings associated with LED, or light-emitting diodes. However, many are not aware that these innovative light sources use specialized devices called LED Driver to operate. LED drivers (also known as LED power supplies) are similar to ballasts for fluorescent lamps or transformers for low-voltage bulbs. They provide LED with the correct power supply to function and perform at their best.

In sum, LED drivers serve two purposes: to convert higher voltage, alternating current to low voltage, direct current, and to keep the voltage or current flowing through the circuit at its rated level.

How does an LED Driver differ from a conventional power supply?

An LED driver is somewhat like cruise control in a car, the power level required changes throughout the LED’s temperature increases and decreases. Without the correct LED driver the LEDs would become too hot and unstable resulting in failure and bad performance. To ensure the LEDs function perfectly the self contained LED driver is required to supply a maintained constant amount of power to the LED.

The LED drivers provide protection to the LED bulbs against current and voltage fluctuations. The drivers ensure that the voltage and current to the LED bulbs remains within the operating range of the LEDs regardless of fluctuations in the mains supply. The protection avoids providing too much voltage and current that would degrade the LEDs or too low current that would reduce the light output.
