What is a LED driver you might ask? A LED driver is an electrical device that regulates power to a LED or a string of LEDs. Using one is very important in preventing damage to your LEDs as the forward voltage (Vf) of a high-power LED changes with temperature. Forward Voltage is the amount of volts the light emitting diode requires to conduct electricity and light up. As temperature increases, the forward voltage of the LED decreases, causing the LED to draw more current. The LED will continue to get hotter and draw more current until the LED burns itself out, this is also known as Thermal Runaway. The LED driver is a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED(s). This helps avoid thermal runaway as the constant current LED driver compensates for the changes in the forward voltage while delivering a constant current to the LED.
