Settings for light loads connected to bus

Abstract

Devices () for selecting settings for illuminating light loads () connected to a bus () comprise controllers () for running processes and for defining, through controls of power converters () connected to the bus (), in response to process results, direct current voltage signals for the bus () and comprise power detectors () for detecting changes in total power consumptions of the illuminating light loads () and for in response to detections of the changes informing the controllers () to run the processes again. This way, links are created between the total power consumption via the bus () and the direct current voltage signal on the bus (), to save energy. The devices () may further comprise receivers () for receiving definitions of optimal individual voltage signals and/or of optimal individual power consumptions and/or of voltage amplitudes and may further comprise power meters () for measuring the total power consumption of the illuminating light loads () for different direct current voltage signals for the bus ().
