Abstract: A luminaire, comprising: a luminaire rear wall for mounting to a wall or ceiling, a printed circuit board, fitted with a plurality of light-emitting diodes and having a connecting cable, as a light-emitting means, and a connecting clamp connected to the connecting cable and to which a supply cable is able to be clamped. A spacer is fixedly mounted to the luminaire rear wall, to which the printed circuit board is releasably attached, with a free space being formed between the printed circuit board and the luminaire rear wall. The whole connecting cable, or a majority thereof, and the connecting clamp are arranged in the free space.

Abstract: Ceiling comprising adjacent luminaries (1), whereby a luminaries (1) is fixed by at least two separate fixation means. The fixation means comprising only one suspension member (2,3) connected to the center of the upper side (6) of the luminaries (1). Furthermore, there is at least one fixation member (22) connecting the luminaries (1) to an adjacent luminaries (1). The lower sides (10) of the luminaries (1) form a substantial flat surface of the ceiling.

Abstract: A luminaire (1) or a system of a first luminaire (1) and a second luminaire (11) for lighting an object (V). Each luminaire has a housing (2; 12) provided with a plurality of tubular lamps (3, 3?, 3?; 13). The housing (2; 12) has a diffuser (7; 17) positioned in a light emitting window (4; 14) and a side wall (5, 5?; 15), which is orthogonal with respect to the light emitting window (4; 14). In the system, the first and the second luminaire (1; 11) abut one another via the side wall (5, 5?; 15) and/or via the light emitting window (4; 14), wherein an edge (6) of the light emitting window (4) of the first luminaire (1) abuts upon an edge (16) of the light emitting window (14) of the second luminaire (11). The diffusor (7; 17) and the side wall (5, 5?; 15) are made from an optically transparent material. Preferably, the light emitting window (4; 14) is provided with a curtain (21; 31).

Abstract: Luminaire including a base unit (9) and a diffuser unit (8). The base unit (9) comprises a housing (4) having an open front side and containing a holder for a lamp (6). The diffuser unit (8) comprises a diffuser plate (7) and side walls (17) extending from the edge of the diffuser plate (7). The diffuser unit (8) is removably fixed in the housing (4), so that the diffuser plate (7) fills up the front side of the housing (4), whereby the side walls (17) extend inside the housing (4). The luminaire furthermore comprises releasable coupling means (25,26) connecting the diffuser unit (8) and the base unit (9).

Abstract: Luminaire comprising at least two lamps (6,7,8) and a light reflecting surface (23) reflecting the light from said lamps. the lamps (6,7,8) radiate light with different colors. The intensity of the light shining from a lamp can be reduced in order to vary the color of the light. The light shines through a diffuser plate (10) forming the front side of the luminaire. A light curtain plate (22) is located between the lamps (6,7,8) and the diffuser plate (10). the light curtain plate (22) contains light reflecting material.

Abstract: A system of a first luminaire (1) and a second luminaire (11) for lighting an object (V). Each luminaire has a housing (2; 12) provided with a plurality of tubular lamps (3, 3′, 3 ″; 13). The housing (2; 12) has a light emission window (4; 14) and a side wall (5, 5′; 15) which is perpendicular to the light emission window (4; 14). In the system, the first and the second luminaire (1; 11) abut one another with their side walls (5, 5′; 15) and/or with their light emission windows (4; 14), such that an edge (6) of the light emission window (4) of the first luminaire (1) abuts an edge (16) of the light emission window (14) of the second luminaire (11). Said light emission windows (4; 14) and said side walls (5, 5′; 15) are made from an optically transparent material. Preferably, the light emission window (4; 14) is provided with a diffusor (7; 17).
