Abstract

Abstract Disclosed is a light fixture having mirrored surfaces angularly related one to the other and about a light source. The mirrors are either all two-way mirrors or a combination of two-way and one-way mirrors. The arrangement of the mirrors about the light source presents a three-dimensional multiple light source effect, particularly a series of discrete light sources which diminish in intensity and size with depth. Variations of the light fixtures hereof include multisided fixtures, for example fixtures triangular, hexagonal, octagonal, etc. in shape, all particularly arranged to present the foregoing optical effect.
