Abstract:
In an illumination system (1) having a control unit (2) and at least one de-central lamp operating device (12, 22) for operating one or more associated lamps (LA), the lamp operating device (12, 22) can be operated in different operational modes. In accordance with the invention the central control unit (2) and the lamp operating device (12, 22) are so configured that the selection and setting of an operational mode for the lamp operating device (12, 22) can be carried out from or via the central control unit (2).
Abstract:
The present invention relates to a luminaire, which comprises a plate-shaped light guide, and first lamps disposed on one or more narrow sides of the light guide and configured to couple light into the plate-shaped light guide, wherein the light coupled into the light guide is emitted via a flat side of the light guide in a first irradiating direction of the luminaire. Said luminaire is characterized in that the first lamps are formed by a plurality of light-emitting diodes and that the luminaire furthermore comprises second lamps and a reflector arrangement associated therewith, by way of which the light of the second lamps is emitted in a second irradiating direction opposite the first irradiation direction.

Abstract:
The invention relates to a lamp (1), especially a suspended lamp, comprising a housing (2) that is provided with a first light emitting area (4) with a first light influencing element (9) on one side thereof while being fitted with a second light emitting area (21) with a second light influencing element (22) on another side for direct illumination. In order to improve indirect illumination of the lamp, the second light influencing element (22) can be moved into at least two different positions (S1, S2, S3).

Abstract:
A luminaire having a box-like luminaire housing for receiving at least one elongate light source and at least one reflector surface arranged—seen from the region to be illuminated—neighboring the light source, the luminaire housing forms a light exit opening which is closed by a light exit element. The light exit element has in a first emission region, located in substance in front of the light source, a first light emission characteristic, and has in a second emission region, separate from the first emission region, a second light emission characteristic different with respect to the first light emission characteristic.
