A lighting control system consists of a device or devices that control electric lighting in an automated manner. Lighting control systems are widely used on both indoor and outdoor lighting of commercial, industrial, and residential spaces. Lighting control systems serve to provide the right amount of light where and when it is needed. [1] This is accomplished using either stand-alone control systems, such as occupancy sensors, or network based solutions that incorporate intelligent communication between system inputs and outputs, usually with the use of one or more central computing devices.

Lighting control systems are often employed to satisfy building codes, or comply with green building and energy conservation programs.

Intelligent or networked lighting control systems typically include devices with embedded processors or industrial computer device, usually include one or more portable or mounted keypad or touchscreen console interfaces, and can include mobile phone operation. These control interfaces allow users the ability to remotely toggle (on-off) power to individual or groups of lights (and ceiling fans and other devices), operate dimmers, and pre-program space lighting levels.

Advantages

A major advantage of a lighting control system over conventional individual switching is the ability to control any light, group of lights, or all lights in a building from a single user interface device. Any light or device can be controlled from any location. This ability to control multiple light sources from a user device allows complex "light scenes" to be created. A room may have multiple scenes available, each one created for different activities in the room. A lighting scene can create dramatic changes in atmosphere, for a residence or the stage, by a simple button press. In landscape design, in addition to landscape lighting, fountain pumps, water spa heating, swimming pool covers, motorized gates, and outdoor fireplace ignition; can be remotely or automatically controlled.

Benefits

Other benefits include reduced energy consumption, and power costs through more efficient usage, longer bulb life from dimming, and reduced emission carbon footprints. Newer, wireless lighting control systems provide additional benefits including reduced installation costs and increased flexibility in where switches and sensors can be placed.[2]

Controlling categories

Lighting control systems provide the ability to automatically power a device based on:

Chronological time is a specific time of day as pre-set timers use. Astronomical times includes sunrise, sunset, a specific day of the week or days in a month or year. Room occupancy might be determined with motion detectors or RFID tags, and is part of security and energy conservation programs. Artificial lighting energy use can be reduced by automatically dimming and/or switching electric lights in response to the level of daylighting, a technology known as daylight harvesting. Mobile phone operated controls can turn on a basic group of circulation—safety fixtures serving exterior—interior locations on approach, or to preheat a "water spa" in advance of returning. Events might include special fixtures for social occasions and holiday lighting, or overall brightness for cleaning. Alarm conditions can include doors opening and motion detected in a protected area, or manual "panic buttons-all lights on" for occupants sensing a possible intrusion. Program logic can tie all of the above elements together using constructs such as if-then-else statements and logical operators.

Theatre

Architectural lighting control systems can integrate with a theater's on-off and dimmer controls, and are often used for house lights and stage lighting, and can include worklights, rehearsal lighting, and lobby lighting. Control stations can be placed in several locations in the building and range in complexity from single buttons that bring up preset options-looks, to in-wall or desktop LCD touchscreen consoles. Much of the technology is related to residential and commercial lighting control systems.

The benefit of architectural lighting control systems in the theater is the ability for theater staff to turn worklights and house lights on and off without having to use a lighting control console. Alternately, the light designer can control these same lights with light cues from the lighting control console so that, for instance, the transition from houselights being up before a show starts and the first light cue of the show is controlled by one system.
