Abstract: A device for shielding outside lights comprising an essentially cylindrical, transparent shield body with a surface which is provided with a zigzag-shaped profile in a vertical direction in order to deflect the radiation from a lighting source incident on the shield body in a desired direction. Triangular projections of the zigzag-shaped profile in a first portion are designed and configured in such a way that the radiation from the lighting source is fully reflected in a desired direction when passing through the first portion of the shield body and triangular projections of the zigzag-shaped profile in a second portion are designed and configured in such a way that the radiation from the lighting source is diffracted in the desired direction when passing through the second portion of the shield body.

Abstract: A low-contrast interior lighting fixture for illuminating a room is disclosed. The interior lighting fixture includes an elongated housing, an elongated horizontally-extending light source supported by said housing, and a first and a second horizontally-extending light guiding reflector assemblies. Each of the reflector assemblies has a top reflective surface, a bottom light-emitting surface, and an edge surface disposed between the top reflective surface and the bottom light-emitting surface. Each edge surface is disposed along opposite longitudinal sides of the elongated light source. A plurality of space-apart louvers extends below the light source and between the first and second reflector assemblies. The reflector assemblies are sized and disposed below the housing so that when the interior lighting fixture is viewed from below, the housing is substantially obscured by the bottom light-emitting surfaces.
