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 ). Preferably, the curtain ( 21; 31 ) exhibits a variation in layer thickness, the layer thickness being thicker at a location on the curtain ( 21; 31 ) close to the tubular lamps ( 3, 3', 3''; 13 ) than farther removed from the tubular lamps ( 3, 3', 3''; 13 ). The object (V) is homogeneously and uniformly illuminated by the system.
