Sun protection with light directing properties - involves lamellas of specific cross-sectional configuration with undersides having profiling providing predetermined light direction for diffuse sky radiation in room

摘要

At least a part of the diffuse sky radiation coming into the upper side (6) of the lamellas (2) is reflected on to the underside (10) of the lamellas above and from there is directed into the room by the profiling. Viewed in the cross-section of the lamellas, the profiling comprises curve segments of variable pitch arranged one behind the other, i.e. curve of the second or higher arrangement. The curve axis of the corresp. curve segments run inclinedly and/or vertically to the main axis (8) of the lamellas (2) and the profiling is formed concavely and/or convexly. USE/ADVANTAGE - To protect a room against direct sunlight, and to control the degree of diffuse light coming into the room.
