Patent ID: 8197102

Claim:
A foldable light recycling cavity comprising a planar substrate having a first side and an opposite second side, said planar substrate having multiple segments; a flex circuit having a first side and an opposite second side, said opposite second side of said flex circuit being bonded to said first side of said planar substrate, said flex circuit being metal; at least one cut channel in said second side of said planar substrate between said multiple segments, each of said at least one cut channels forming at least one fold line on said first side of said planar substrate; at least two light emitting diodes mounted on said first side of said flex circuit; and wherein folding said planar substrate along said at least one fold line forms a light recycling cavity, said flex circuit acting as a hinge during folding said planar substrate, and said flex circuit on said multiple segments of said planar substrate forms the walls of said light recycling cavity.
