Abstract: In a luminaire, comprising a light source (2) having at least one LED and a heat sink (4) for cooling the LED, the light source (2) is arranged pivotably with respect to the heat sink (4), wherein three lever arms (6, 8, 10) that act on the light source (2) are provided and the luminaire is designed such that the light source (2) is pressed against the heat sink (4) by the three lever arms (6, 8, 10). Moreover, a spring element (12), which acts on a first (6) of the three lever arms (6, 8, 10), and an adjusting means (14) for adjusting a second (8) of the three lever arms (6, 8, 10) are provided.

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.

Abstract: Disclosed is a light (1) comprising means (3a) for retaining and electrically connecting at least one elongate light source (2) and a light-influencing element (10) which is located next to the light source (2) and is composed of several individual elements (15). Said elements (15) that form the light-influencing element (10) can be swiveled or rotated independently of each other about an axis that extends substantially parallel to the longitudinal axis of the light source (2).

Abstract: The invention concerns a luminaire having a housing, which at the emission side of the luminaire has a housing opening, having, situated in the housing, connection means for at least one lamp which define the position thereof in the housing, having a light guiding element which is so positioned that, in the main emission direction, it is located in front of the lamp to be used, and having at least one diffuser arranged at the side neighbouring the light guiding element, which has a shaping projecting beyond the edge of the housing, having a flank rising towards the light guiding element. In order to improve the light guiding and/or light emission of the diffuser, the shaping has further a flank falling towards the light guiding element.

Abstract: A luminaire with a plurality of light-emitting diodes in a decentralized arrangement. To improve the light emission pattern issued by the luminaire, the emission region defined by the light guide emission ends is smaller than the arrangement region defined by the totality of the light-emitting diodes.

Abstract: An optical element (1) for reflecting and/or redirecting light rays (L1) entering therein and again emerging therefrom consists of a transparent base body (2) which is so structured and/or formed that, with the formation of reflection surfaces (8) bounding the base body (2), at least a part of the light rays (L1) impinging upon the reflection surfaces (8) upon emergence from the transparent base body (2) are totally reflected, and at least one cover body (9) arranged behind the reflection surfaces (8). The reflection surfaces (8), and the surfaces of the cover body or bodies (9) towards the reflection surfaces, are adapted to one another such that between them there remains a thin gap (10) or only point contacts exist.

Abstract: A luminaire (1) has means for holding and for electrically connecting a tube-like lamp (2) and a back reflector (4), extending over the length of the lamp (2), which is provided for the purpose of reflecting a part of the light emitted from the lamp (1) counter to a certain emission direction. In the back reflector there are provided through-openings (5) which are provided for the purpose of allowing a part of the light emitted from the lamp (2) to pass through in the emission direction, whereby pot reflectors (6) adjoin onto the through-openings (5) in the back reflector (4) in the emission direction. The luminaire distinguishes itself through the variety of the illumination effects which can be achieved therewith, which however have no effect on the functionality of the luminaire for room illumination or for the illumination of workplaces.

Abstract: A lighting strip system, including a carrier rail (3), which bounds a hollow space, to be mounted on a wall or ceiling, a plurality of electrical wires (12) running longitudinally in the hollow space, for the delivery of supply voltage and, if applicable, control signals. The lighting strip system also includes a plurality of coupling parts (13a) arranged in the hollow space with spacing in the longitudinal direction of the carrier rail (3). The coupling parts are electrically connected with the wires (12). A plurality of elongate lights (A1, A2, A3 . . . ) can be mounted one after another on the carrier rail in longitudinal direction. Electrical counter-coupling parts (13b) are provided on the lights (A1, A2, A3 . . . ) which when placed on the carrier rail (3) enter into the hollow space and make electrical plug contact with corresponding coupling parts (13a).
