LED controller
Short nameLEDC
Other nameLED lighting controller
Full nameLight-emitting diode controller
TypeModule-based LED control device
Main functionRegulation of the luminance of the LED[1]

An LED controller (short for light-emitting diode controller[2]), also known as LED lighting controller,[3] or simply referred to as LEDC,[4] is an electronic device that operates an LED.[5] Its basic functions are to regulate the current and voltage fed to the LED,[6] as well as its light-emitting pattern, brightness and color.[7] The device is different from an LED driver.[8]

An LED controller, which has up to 16 channels,[9] is a light controller equipped with an LED driver.[10] The device has all the control capabilities of the generic LED driver[11] with additional features including communication and temperature monitor.[12]

LEDCs can be categorized into various types, such as Wi-Fi LED controllers, Bluetooth LED controllers,[13] DALI and DMX LED controllers.[14] The units can be used in the fields of automotive lighting,[15] bicycle lighting,[16] and residential lighting. The representative manufacturers of such devices include Analog Devices,[17] MiBoxer,[18] and Texas Instruments.[19]

History

The LT3756, launched by Linear Technology in 2008, is one of the early LED controllers.[20] In 2012, TI introduced the industry's first LEDC with constant power regulation.[21]

In March 2014, Marvell Technology rolled out the 88EM8189, which is touted as the smart AC/DC LED controller that offers I²C control interface.[22]
