The lighting control system is adopted for good lighting systems in a most economical way. This process reduces the cost and energy consumption. The control systems are like, variable light level control or dimming, switching, networking, scheduling or time based control, etc. Preset Control station system controls the dimmed lighting in areas like conference centers, churches and auditoriums. Relay module performs input, output functions. A high-speed data bus interconnects the modules and enables them to share input and output actions with each other and the system controller. A system controller contains the main processor and controls the lighting process, read the whole data and displays on its LCD screen. Dimming is an effective tool used in lighting control system, a dimmer module is designed to reduce energy consumption, provide appropriate light levels for tasks. Switching control systems includes simple low voltage wall switches, networked button stations, touch-tone telephone interface, and personal PC workstation access. Time-based lighting control can save substantial energy by automatically turning off lighting after normal working hours in open offices, lobbies, exterior and sites. A wide range of lighting control systems is manufactured by a host of manufacturers.
