Some well-known manufacturers of intelligent lighting control systems include the following:
LC&D, Lutron, Litetouch, Vantage, and Crestron.
Localized Control Panels
Lighting control intelligence does not have to be remotely located as in Figure
23.5. Smaller control systems can be located to incorporate only the luminaires in a single room as in Figure 23.7. These smaller, local control systems usually control up to six lighting loads and can be connected to control devices anywhere in the room. A typical situation may be an auditorium or a home theater where numerous lighting loads in a space need to be controlled from numerous locations. The local control system can reduce the number of traditional wall-mounted light switches used and can add dimming and scene
creating abilities. A normal “switched” lighting layout for a space may look like Figure 23.6. In this case, the wall sconces, wall-wash luminaires, steplights, and pendants are each controlled by a light switch. A local control system would be installed in place of the light switches. The groups of luminaires would now be considered “lighting loads,” and each would be connected back to the local control system.
Figure 23.6 Using standard light switches to control complex spaces can lead to an over-abundance of light switches.
Figure 23.7 A localized “whole room” control system can reduce clutter and confusion.
The local control system would have a set of visible buttons that would be programmed to turn on the various lighting loads. We can keep the programming simple and program each button to control one lighting load, or we can program each button to activate a scene of multiple lighting loads at varying light levels. We can also install other control devices capable of telling the local lighting control system to activate the same scenes. Figure 23.7 shows how a space might look when such a system is implemented. These local systems can often be retrofit into existing lighting situations. A common candidate is a room that has four or five wall switches in one location. Rather than fuss with each switch, the local control system replaces all of the switches and opens up the possibility of programming scenes and dimming levels and activating them with a single button press.
