Constructive occlusion lighting system and applications thereof

摘要

A luminaire includes at least one light source, at least one reflector having a reflector cavity and an optical element positioned to receive light reflected from the at least one reflector cavity. The luminaire does not include a mask or other structure located within the opening of the luminaire that would partially occlude light exiting the luminaire—light can thus exit the luminaire unimpeded. In some embodiments, the at least one reflector cavity is semi toroidal. Moreover, in some embodiments, the optical element includes a reflective optical element, a refractive optical element or a combination thereof. Methods of lighting a surface are also described.

1. A luminaire comprising:
a reflector comprising an inner surface defining at least one reflector cavity; a plurality of light emitting diodes positioned within the luminaire to direct light into the at least one reflector cavity; and an optical element at least partially positioned within the reflector cavity to receive light reflected from the at least one reflector cavity, wherein the optical element is positioned within the reflector cavity such that light received on the optical element from the reflector cavity exits the luminaire unimpeded.
