Illumination system using edge-illuminated hollow waveguide and lenticular optical structures

摘要

An illumination system having a hollow waveguide including first and second light directing arrays (LDA), each having a plurality of generally lenticular prisms defined thereon and arranged generally orthogonally with respect to each other. Light rays from a light source enter the waveguide through a light input side and emerge from the waveguide through a light output side at a predetermined flux and angular distribution. The light output flux and angular distribution can each be independently controlled in accordance with the present invention by the LDAs to provide an illumination system that can be configured for various light output distribution and intensity requirements.
