LED Drivers
LEDs are low-voltage light sources, requiring a constant DC voltage or current to operate optimally. Operating on a low-voltage DC power supply enables LEDs to be easily adapted to different power supplies, permits longer stand-by power, and increases safety. Individual LEDs used for illumination require 2-4V of direct current (DC) power and several hundred mA of current. As LEDs are connected in series in an array, higher voltage is required.
In addition, during operation, the light source must be protected from line-voltage fluctuations. Changes in voltage can produce a disproportional change in current, which in turn can cause light output to vary, as LED light output is proportional to current and is rated for a current range. If current exceeds the manufacturer recommendations, the LEDs can become brighter, but their light output can degrade at a faster rate due to higher temperatures within the device which leads to a shorter useful life. One definition of useful life for LEDs is the point at which light output declines by 30 percent. LEDs, therefore, require a device that can convert incoming AC power to the proper DC voltage, and regulate the current flowing through the LED during operation. The driver converts 120V (or other voltage) 60Hz AC power to low-voltage DC power required by the LEDs, and protects the LEDs from line-voltage fluctuations.
LED drivers may be constant voltage types (usually 10V, 12V and 24V) or constant current types (350mA, 700mA and 1A). Some drivers are manufactured to operate specific LED devices or arrays, while others can operate most commonly available LEDs. LED drivers are usually compact enough to fit inside a junction box, include isolated Class 2 output for safe handling of the load, operate at high system efficiency, and offer remote operation of the power supply.
