Luminaire system

A luminaire comprising:

• a light source;
• a plurality of prisms defining, at least in part, an interior of a hollow light guide for redirecting the light from the light guide substantially perpendicular to a longitudinal axis of the light guide, 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 plurality of prisms adjacent the light source that control the spreading of light along the longitudinal axis of the light guide.

A method of redirecting light comprising:

• providing a light source;
• redirecting light from the light source in a predetermined direction with a plurality of prisms, each prism 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
• redirecting light from the light source toward the plurality of prisms.

A luminaire comprising:

• a light source;
• a light guide that receives light radiating from the light source, the light guide being curved;
• and
• a plurality of prisms adjacent the light guide for redirecting the light from the light guide in a predetermined direction, each prism having an included angle that is substantially uniform along a longitudinal axis thereof, the included angle of each prism varying as a function of the distance from the light source.
