Things to consider before selecting an LED driver 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. The LED driver is a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED(s). The LED will continue to get hotter and draw more current until the LED burns itself out, this is also known as Thermal Runaway. As temperature increases, the forward voltage of the LED decreases, causing the LED to draw more current. Forward Voltage is the amount of volts the light emitting diode requires to conduct electricity and light up. Using one is very important in preventing damage to your LEDs as the forward voltage (V f) of a high-power LED changes with temperature. It is a crucial piece to an LED circuit and to operate without one will result in system failure. What is an LED driver you might ask? An LED driver is an electrical device that regulates power to an LED or a string of LEDs. That’s why I wanted to write a quick post explaining the varieties, what makes them different, and things you should look for when choosing the LED driver(s) for your lighting application. There are so many different types and variations that it can seem a little overwhelming at times.
