LED power supplies, also known as LED drivers, are electronic devices that provide the necessary voltage and current needed to power Light Emitting Diode (LED) lights. These electronic devices produce a direct current (DC) output, often adjustable, to drive the LEDs while keeping their performance in the safety limits. Types of LED power supplies includes constant voltage, dimmable, and constant current, depending on whether there is to be a continuous or varying level of lighting is desired. LED power supplies have several advantages over traditional power supplies, including greater efficiency, smaller size, and lower amounts of heat production.
