Abstract:
Lamellae (10, 11, 12, 13, 23, 24, 25, 69, 83, 84, 206, 207) for light deflection and scattering of radiation comprising a first portion (5, 26, 27, 28, 208, 209) disposed in a radiation area having a step-like gradation of lamella leaves consisting of treadboards (6, 35, 36, 45, 71, 72, 73, 74, 104, 106, 108) and risers (34, 37, 46, 103, 105, 107) where an inclination .beta. of at least a first treadboard at least in a starting point forms an incline from the radiation area to an interior space (33), and a second portion (4, 29, 30, 31), characterized in that:(a) at least an upper side of said first portion includes at least one treadboard with an inclination deviating at least at a starting point (8, 51, 54, 118) relative to at least portions of said second portion (6, 66, 53, 29, 30, 31),(b) the inclination .beta. at least in the starting points (8, 51, 54) of said first treadboard (16) and at least parts of said second portion (6, 66, 53) form an obtuse angle .OMEGA. relative to each other, and(c) daylight radiation impinging onto lamellae (10, 11, 12, 13, 23, 24, 25, 69, 83, 84, 206, 207) is deflected by said first portion (5, 26, 27, 28, 208, 209) into the radiation area and daylight impinging onto said second portion (4, 29, 30, 31) is deflected into the interior space (33).
