Method & Apparatus for Lighting

摘要

A lighting fixture includes a directional light source that produces a plurality of light rays. An optical module is coupled to the directional light source to focus the plurality of light rays into a beam of light rays to be output by the lighting fixture. The angular distribution of a majority of the beam relative to a vector normal to a ceiling on or near which the fixture is to be installed is in a range of 70 to 95 degrees. A blocking structure is used to block a direct view of the beam of light when the fixture is installed such that only indirect light is primarily visible from a viewer at least in or around a working plane substantially parallel to the ceiling.
