LIGHTING SCENE CONTROL PANEL AND CONTROL CIRCUIT

摘要

A plurality of groups of linearly adjustable control potentiometers control respective lights of a given light scene in a given area. A particular group of potentiometers to control the scene is selected by a respective push-button switch on the control panel. Each of the potentiometer control sliders has an LED which is illuminated when its group of potentiometers is selected. Each of the control potentiometers controls a respective dimmer control circuit. Respective fader circuits are connected to each dimmer control circuit. All fader circuits are adjusted by a single potentiometer having a logarithmic response function. The single adjustment potentiometer is mounted on the control panel. All of the dimmer control circuits are remotely located from the control panel. The control panel is covered by a solid cover or a translucent cover through which only illuminated LEDs on the potentiometer sliders are visible. Thus, the group of potentiometers controlling the scene is visible and the adjustment position of each individual potentiometer of the group relative to the other potentiometers of the group is visible.
