A Home LED Light Control System with an Automatic Brightness Tuning to Reduce the Difference in Luminous Decay

This paper presents a design of the software and hardware modules of an embedded board with both a sensor and an interface circuit which not only control home light-emitting diode (LED) lighting appliances but also reduce their differences in brightness caused by luminous decay. This design consists of four parts: an automatically adjusted LED driver, environment illumination detection, a wireless remote control unit and an automatic brightness control.
