Abstract: A luminaire (10) for illuminating an area of a building, in particular an office, comprising lighting means (14) for providing light, a support means (12) on which the lighting means (14) can be mounted, a control unit (for controlling the lighting means (14) using control commands, a communication means (24) for communicating with the control unit (22), the communication means (24) having a data carrier (26), in which data that can be read out by the control (22) can be stored for the purpose of controlling the luminaire (10), a power source (30) or a power source connection for a power source, having the following additional features: a timing module (28), disposed in or on the luminaire (10), for autonomously supplying the current time and, if appropriate, the current date, and the data stored in the data carrier (26) can be read out in accordance with the time information supplied by the timing module (28) for the time-dependent control of the luminaire (10).

Abstract: The invention relates to an intelligent lighting device with multiple luminaires, which are at least partially coupled to each other with a wireless communication device. For this purpose, the luminaires preferably have communication modules with transmitter/receiver devices, via which the luminaires can communicate with each other. It is thereby provided that in accordance with the current operating mode of one of the luminaires at least one of the other luminaires can adopt a different predefined operating mode. Said luminaire can, for example upon the switching on of a luminaire or when one of the luminaires detects a person by means of a sensor device in the area of the luminaire, go into a working level with a predefined light intensity and the other luminaires located in the vicinity of said one luminaire go into a background illumination, i.e. in an illumination with a lower illumination level (background level).

Abstract: The invention relates to a method for operating a lamp comprising a first light for direct lighting and a second light for indirect lighting of an object, as well as a controller controlling the first and second light emitting means separately, and at least one light sensor is mounted on the lamp and connected to the controller for detecting the amount of light in the area, including any extraneous light. The controller has means to subtract the indirect amount of light reaching the light sensor from the total amount of light coming from the second light emitting means as detected by the light sensor, and the amount of direct light produced by the first light emitting means reaching the light sensor, as well as any existing extraneous light reaching the light sensor, in order to control the lamp, in particular by switching it on or off.
