Patent ID: 8347492

Claim:
A method of making an arrangement for collecting or emitting light, comprising: a) providing a flexible sheet of material as a substrate for a plurality of light collecting or emitting devices and for formation of a respective light coupler for each of the plurality of light collecting or emitting devices; b) mounting the plurality of light collecting or emitting devices being spaced apart on the sheet, wherein the light collecting or emitting devices convert light into electricity or electricity into light respectively; c) the sheet having thereon electrical leads for interconnection to each of the plurality of light collecting or emitting devices; and d) for each light collecting or emitting device, forming a respective light coupler by forming a plurality of reflectors on the sheet around the intended periphery of the respective light collecting or emitting device, by— i) applying reflective material to selected areas of the sheet to be formed into reflectors; ii) selectively forming cut lines and fold lines around substantially the full periphery of each of said selected areas; and iii) folding each of the selected areas of the sheet, about said fold lines, away from a plane of a portion of the sheet on which the light collecting or emitting device is mounted, such that a light coupler is formed, wherein the interior of the coupler is reflective and the coupler is substantially closed around a main axis of light propagation into or from the respective light collecting or emitting device.
