First Claim
1. A luminaire comprising:
- a light source;
a plurality of prisms for redirecting light from the light source in a predetermined direction, each of the plurality of prisms having an included angle that is substantially uniform along a peak of each prism, the included angle of each prism varying as a function of the distance from the light source; and
a reflector for redirecting light from the light source toward the plurality of prisms.

Abstract
A luminaire and method are provided comprising a light source, a plurality of prisms, such as linear prisms, for redirecting light from the light source in a predetermined direction, and a reflector for redirecting light from the light source toward the plurality of prisms. Each of the linear prisms has a longitudinal axis and the light source has a longitudinal axis, wherein the longitudinal axes of the linear prisms are substantially parallel to the longitudinal axis of the light source. Each of the plurality of prisms has an included angle, which can vary as a function of the distance from the light source. The angle can vary stepwise or continuously. In one embodiment, each of the plurality of prisms adjacent the light guide has an included angle in the range of between about 35 and 45 degrees. In another embodiment, the included angle is substantially uniform among the prisms. The luminaire optical sheet can be made out of continuous sheet with built in hinge points to provide a complete light redirecting structure.
