Lighting Control System

Lighting Control System
- consists of a device,
- typically an embedded processor or industrial computer,
- that controls electric lights for a building or residence.
- Lighting control systems usually include one or more keypads interfaces.

These interfaces allow users the ability to toggle power to lights and fans, and dim lights.
A major advantage of a lighting control system over conventional lighting is the ability to control any device from any interface.
For example, a master touch panel might allow the user the ability to control all lights in a building, not just a single room. In fact, any lighting might be controlled from any location.
In addition, lighting control systems provide the ability to automatically power a device based on programming events such as:

1. Chronological time
-Chronological time is a time of day or offset from a time
2. Astronomical time
-Astronomical times includes sunrise, sunset, a day, or specific days in a month or year.
3. Room occupancy
-Room occupancy might be determined with motion detectors.
4. Alarm conditions
-Alarm conditions might include a door opening or motion detected in a protected area.
5. Program logic
-Program logic can tie all of the above elements together using constructs such as if-then-else statements and logical operators.
