Patent ID: 8029164

Claim:
A light recycling cavity with integral light taper comprises a planar substrate having a first side and an opposite second side; a metal layer on said first side of said planar substrate, said metal layer having a mirrored surface, said metal layer having a first end and a second end, said metal layer having at least two bond pads at said first end, said metal layer having at least four isolation islands at said first end; at least three cut channels in said second side of said planar substrate; said at least three cut channels forming at least three fold lines on said first side of said planar substrate, at least one of said isolated islands extending across at least one fold line; at least four light emitting diodes mounted on said at least four 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 there fold lines forms a four sided light recycling cavity at said first end and a light taper at said second end, said metal layer acts as a hinge during folding said planar substrate and said metal layer forms the walls of said light recycling cavity and said light taper, light emitted by said at least four light emitting diodes exiting at said second end.
