Abstract

An illumination control system provides wireless data transmission with a lamp through a mobile communication device. The lamp has a built-in wireless communication module and a microcontroller. The microcontroller stores a location of the lamp with latitude-longitude values and height values. Accordingly, a user may use the mobile communication device to read the latitude-longitude values and height values of the lamps to achieve an indoor positioning function by calculating a positioning information of the user through indoor positioning algorithms, and thereby enable illumination control through the mobile communication device according to the positioning information.
