Lighting control system is a device, typically embedded processor or industrial computer that controls electric lights for a building or residence. They usually include one or more keypads or touch panel interfaces. These interfaces allow users to toggle power to lights and fans, dim lights and program lighting levels. A major advantage of a lighting control system is the ability to control any device from any interface. In fact, any light might be controlled from any location. In addition, this system provides the ability to automatically power a device based on programming events such as chronological time, astronomical time, room occupancy, events, alarm conditions as well as program logic. Variable lighting control systems are currently used with only incandescent and fluorescent lamps. They offer infinite levels based on the availbale sunlight.
