Light source switching device for lighting unit, has movement detector to detect moving objects in detection area and to generate activation signal that is transmitted to another device

摘要

The device (6) has a timing circuit to generate a signal corresponding to an activation period for a light source (2) of a lighting unit (1). A movement detector (10) detects moving objects in a detection area and generates an activation signal. The signal is transmitted to a device that switches a light source arranged in another lighting unit. A receiver receives the activation signal generated by the latter device. An Independent claim is also included for an arrangement comprising of a group of lighting units.
