Most people are familiar with the energy savings and long life spans associated with LEDs, or light-emitting diodes with increasing energy regulations. But why you need an LED driver, and what type of driver you may need.
Every LED light source requires a driver. Some LEDs already include an integrated driver within the bulb. LEDs designed for household use (bulbs with E26 / E27 or GU24 / GU10 bases and that run on 120V) typically already include a driver. However, low voltage LED light sources, such as some MR- bulbs (MR11s and MR GU5.3s, MR8s) and tape light, as well as certain fixtures, panels, or outdoor-rated lights, usually require a separate Non Dimmable LED Driver. When an LED that requires a separate driver stops working before the end of its rated lifetime, it can usually be saved if the driver is replaced.
Most places supply higher voltage (120-277V), alternating current electricity. An LED driver’s main purpose is to rectify higher voltage, alternating current to low voltage, direct current.
LED Driver Power Supply also protect LEDs from voltage or current fluctuations. A change in voltage could cause a change in the current being supplied to the LEDs. LED light output is proportional to its current supply, and LEDs are rated to operate within a certain current range (measured in amps). Too much or too little current can therefore cause light output to vary or degrade faster due to higher temperatures within the LED.
There have two purpose for the 12V Constant Voltage LED Driver: 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.
