A room light (2) comprises a light sensor (7), IR-sensor (8) and a presence sensor (9) to control the light according to the presence or absence of a person. An additional IR-sender (10), coupled with the presence sensor, sends on/off signals to additional lights in the room. A room light has a light sensor (7) to control brightness depending on daylight, an IR-sensor (8) for remote operation and a presence sensor (9) to switch the light (2) on or off depending on the presence or absence of a person. There is an additional IR-sender (10), operating with the presence sensor, which sends on/off signals to at least one additional light. An Independent claim is also included for an arrangement as above having a different configuration of the two sensors system. |
