Abstract

The luminaire has a louvre attachment (5) in the luminous window (2). The louvre attachment is provided with a first and a second reflector (6, 7), which are interconnected by parallel louvre strips (8) which are bent in cross-section into a triangular shape from a strip of sheet material with lateral edges (9). The strips (8) have their seams (10) in the luminous window (2) and the lateral edges (9) lie sideways against one another. The attachment has an even luminance and a luminous window of great effective size.
