Patent ID: 8029165

Claim:
A foldable light recycling cavity comprises a planar substrate having a first side and an opposite second side; a metal layer on said first side of said planar substrate forming at least two bond pads and at least two isolated islands; at least one cut channels in said second side of said planar substrate; each of said at least one cut channels forming at least one fold line on said first side of said planar substrate, at least one of said isolated islands extending across at least one fold line; at least two light emitting diodes mounted on said at least two isolated islands; said at least one of said isolated islands extending across at least one fold line being an electrical connection between said at least two light emitting diodes; at least two contacts on said at least two bond pads; and wherein folding said planar substrate along said at least one fold line forms a light recycling cavity, said metal layer acts as a hinge during folding said planar substrate and said metal layer forms walls of said light recycling cavity.
