LED drivers are the specialized device for LED technology similar to the transformer to low-voltage bulbs. They help LEDs by providing electricity they need to perform and function at their best. This is used to prevent damages to LEDs at higher energy.

As temperature increases, the forward voltage of the LED decreases; forward voltage is the number of volts LED requires to emit light and conduct electricity, causing the LED to draw more current. As a result, LED emits more heat and consume more current give leads to LED burn out. The LED driver works the same as the transformer giving an output which matches the electrical characteristic of LEDs. Due to the LED driver, there are fewer chances of LED burn out while delivery the constant current.

There are two type of drivers -high-voltage AC input (90-300 V) and low voltage DC input LED drivers (5-36 V DC) type are recommended mainly because of their stability and reliability. You need to consider some factors before buying LED drivers like whether the need for constant current or voltage. Other factors like types of LEDs, current capacity, fixture application, dimming properties. Dimmable LED drivers are gaining popularity and work with 0-10 V dimming or PWM dimming. Uses of drivers have been increased to prevent further damage to LED products.
