  • Luminaire and a lighting panel for a luminaire
    Patent number: 7631980
    Abstract: A luminaire comprising a light source and a lighting panel in front of the light source, wherein light radiation from the light source is transmitted through the lighting panel before it leaves the luminaire. The material of the lighting panel is transparent, and the front surface of the lighting panel is profiled in order to reduce outgoing light radiation that is at a relatively small angle to the plane of the lighting panel. Walls (7, 8) of a less translucent material are embedded in the transparent material of the lighting panel, which walls (7, 8) extend substantially perpendicularly to the plane of the lighting panel.

  • Luminaire and Lamellae Louver Therefor
    Publication number: 20080130287
    Abstract: The luminaire has concave side reflectors (2) defining the width W of a light emission window (1). A plurality of V-shaped lamellae (10) is present between the side reflectors (2) in the light emission window (1). Their outer edges (11) each have a central portion (11a) which is concavely curved and straight end portions (11b) which each have a length of 0.15 to 0.25 W. The lamellae louver (20) is suitable for use in the luminaire. The occurrence of glare when the luminaire is used in an office environment is counteracted.
