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: The invention relates to an electrical supply and control system for supplying electrical energy to an electrical device arrangement, which includes at least one sensor means, and for remote-controlling said electrical device arrangement. In order to provide an inexpensive conductor rail system, which permits the control of connected electrical devices depending on an environmental situation, the invention provides at least one profiled conductor rail with a power conductor and control lines extending along the conductor rail. Adapters are provided for releasably attaching at least on electrical device of the electrical device arrangement to the conductor rail and for, thereby, electrically connecting the power conductor and the control lines to the device.

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.
