Device for limiting passage of light through window opening has outlet stop with several light outlet shafts, each associated with inlet shaft to form through shaft from inlet to outlet sides

摘要

The device has a raster with light inlet shafts on the light incidence side, inclined relative to the direction of incidence to limit direct incidence of light from a source and in a two-dimensional arrangement and a stop arrangement on the outlet side for limiting the outlet angle relative to a normal to the outlet surface. The outlet stop has light outlet shafts, each associated with an inlet shaft to form a through shaft. The device has a raster (9) with several light inlet shafts on the light incidence side, inclined with respect to the direction of incidence to limit the direct incidence of light from a source and arranged in a two-dimensional arrangement and a stop arrangement on the outlet side for limiting the outlet angle relative to a normal to the outlet surface. The outlet stop has several light outlet shafts, each associated with an inlet shaft so that a through shaft is formed from the inlet to the outlet side in each case. Independent claims are also included for the following: a raster form inventive device and an arrangement of an inventive device in a room with window opening.
