Main functionRegulation of the luminance of the LED

An LED controller (short for light-emitting diode controller[1]), also known as LED lighting controller,[2] or simply referred to as LEDC,[3] is an electronic device that operates an LED.[4] Its basic functions are to regulate the current and voltage fed to the LED,[5] as well as its light-emitting pattern, brightness and color.[6] The device is different from an LED driver.[7]

An LED controller, which has up to 16 channels,[8] is a light controller equipped with an LED driver.[9] The device has all the control capabilities of the generic LED driver[10] with additional features including communication and temperature monitor.[11]

LEDCs can be categorized into various types, such as Wi-Fi LED controllers, Bluetooth LED controllers,[12] DALI and DMX LED controllers.[13] The units can be used in the fields of automotive lighting,[14] bicycle lighting,[15] and residential lighting. The representative manufacturers of such devices include Analog Devices,[16] MiBoxer,[17] and Texas Instruments.[18]

History

The LT3756, launched by Linear Technology in 2008, is one of the early LED controllers.[19] In 2012, TI introduced the industry's first LEDC with constant power regulation.[20]

In March 2014, Marvell Technology rolled out the 88EM8189, which is touted as the smart AC/DC LED controller that offers I²C control interface.[21]
