Several light sources (2) can be controlled independently of one another with the same control conductor (9), with the light flow varied according to requirements. The control signals can be coupled directly to the control electronic appts. (4) for regulating the lighting strength with high frequency drive of light tubes. - The control signals can easily be transmitted via an infrared link, a radio link or a carrier frequency, and the control unit can record and read off the total energy usage. The light source control equipment (2) can be provided with equipment for supply of auxiilary voltage to presence detectors (1) or control appts. |
