Abstract: Lighting devices with lighting means, transmitting device for transmitting an electromagnetic data signal and energy buffer for current supply of the transmitting device are to be protected from exhaustive discharge. Thereto, an activation device is provided, by which the transmitting device can be activated from an energy-saving mode, in which the transmitting device is switched off, into an operating mode, in which the transmitting device is switched on for operationally transmitting the electromagnetic data signal.

Abstract: The individual configuration of beacons in lighting systems is to be simplified. Therefore, a lighting system with a lighting device and a beacon arranged in or at the lighting device is provided. The lighting system comprises a sensor device for acquiring an environmental parameter relating to an environment of the lighting system. Moreover, the beacon is formed to automatically configure itself based on the environmental parameter.

Abstract: The invention relates to a lighting device, comprising a first lighting means and a transmission module for wireless transmission and for providing a position identification signal comprising position determination data. The lighting device also comprises an electronic operating device for operating the first lighting means, wherein the electronic operating device is coupled on the input side to an electrical supply connection of the lighting device and on the output side to the first lighting means by a first connection device. The electronic operating device comprises an energy converter for supplying the transmission module with electrical energy. The invention further relates to a system for providing a position indication having a plurality of such lighting devices. In addition, the invention relates to a method for operating a lighting device having a first lighting means by providing a position identification signal comprising position determination data by means of a transmission module.

Abstract: The invention relates to a lighting device for providing a position identification signal, wherein the lighting device comprises a lighting means. A transmitting unit comprising an antenna element transmits the position identification signal in the form of a directed radio signal having a specifiable emission characteristic during intended operation, wherein the position identification signal comprises a position determination data regarding a position of the transmitting unit and/or of the lighting means. The invention further relates to a lighting system having a plurality of lighting devices. In addition, the invention relates to a method for operating a lighting device having a lighting means and a transmitting unit.

Abstract: The invention relates to a method for operating a transmission device of a lighting device comprising an illumination device, wherein the transmission device is arranged in or immediately on the illumination device and wirelessly emits a radio signal with identification signals that are specific to the transmission device, wherein the radio signal is emitted according to exactly one predetermined radio standard, wherein the radio signal contains the specific identification data at least in two data formats that are different from each other.
