Controlling lighting systems in buildings and exterior lighting systems

摘要

The lights are switched on or off according to need. It is assumed that it would be determined, which lights by which operating elements are cleared for switching on or off. An operating element is operated and it is monitored whether the instantaneous condition of the lights released by the operating element, correspond with the last activated light scene of the corresp. operating element. When the monitoring results in differences, the lights are switched on, corresp. to the last light scene last activated by the operating element. With correspondence the lights of the activated light scene are switched off, if the operating duration of the operating element has not exceeded the light changeover time. The operation duration of an operating element exceeding a freely selectable changeover time, results in a light scene changeover. After the expiry of the changeover time of the last selected light scene, the first light scene of the corresp. operating element is reactivated. The number of light scenes per operating element is freely selectable.
