Abstract

The present invention relates to a louvred luminaire, fitted with a rod-shaped fluorescent lamp (12), in the case of which luminaire the fluorescent lamp is arranged in the centre in the upper region of a box-shaped luminaire housing of relatively large width, the light exit opening being subdivided, transversely with respect to the longitudinal axis of the lamp, essentially into three fields of approximately identical width and the transverse lamellae (11) in the central region and also the transverse lamellae (15, 16) in the two side fields running horizontally and parallel with respect to the housing ceiling of the luminaire, the transverse lamellae (15, 16) in the side fields terminating at the bottom at the same level as the transverse lamellae (11) of the central region and the transverse lamellae (15, 16) in the side fields extending at the top until closer to the lamp (12) than the transverse lamellae (11) in the central region. <IMAGE>
