Title:
LUMINAIRE DEVICE
Document Type and Number:
WIPO Patent Application WO2004025170
Kind Code:
A3
Abstract:
A luminaire including a lamp (100), reflector (105), collimator (110) and optional waveguide. The waveguide can be solid or hollow or include several serially-arranged total internal reflection (TIR) components for redirecting light that has entered the waveguide. In one embodiment, the TIR components are prisms (125 a-c), but are provided without metallized coatings thereby significantly reducing manufacturing costs. In another embodiment, components are arranged in a vertical orientation such that light is directed downward through a collimator (110) or upward, either directly from the lamp (100) or as a result of reflection from the reflector (105).
