Simple applications only require a push-button to operate the lighting control system. Control panels with displays are recommended for sophisticated applications and can also be used to program the lighting system. A remote control device allows light scenes to be recalled from anywhere in the room.
A push-button closes or opens a circuit to switch a luminaire group or light scene on or off. To use different functions, a system requires several push-buttons. The functions are determined when the lighting control system is installed.
A switch opens and closes a circuit. It locks into position and does not require continuous pressing as does a push-button. A light switch controls the lighting by switching it on or off.
A remote control is used to control the light separately from wall-mounted control panels. In conference rooms, a remote control is a convenient device to recall different light scenes from anywhere in the room. An infrared remote control requires an IR receiver to recall any functions.
Graphical User Interface (GUI)is the familiar way of interaction with software on computers or control panels based on graphical images. Simple user interfaces prevent users having to learn complex command languages and simplify the operation. A GUI can be combined with a touch screen so that interaction takes place directly on the screen.
