A LIGHTING DEVICE FOR ILLUMINATION OF A SURFACE

摘要

The lighting device (1a, 1b, 1c) comprises a diffuse light source (2), a screening device (8) screening off part of the light radiating from the light source (2), and an opening in the lighting device (1a, 1b, 1c), through which the light is allowed to radiate. The lighting device (1a, 1b, 1c) furthermore comprises a lamella device (4) having at least two light absorbing and/or reflecting lamellae (6). Light allowed to radiate through the lamellae (6) forms a VBA (Visual Beam Angle) of less than approximately 30°.
