Abstract
Disclosed is a method of making an arrangement for collecting or emitting light. A flexible sheet of material serves as substrate for a plurality of light collecting or emitting devices mounted in spaced relation on the sheet. The sheet has thereon electrical leads for interconnection to each device. For each device, a respective light coupler is formed by (1) forming a plurality of reflectors on the sheet around the intended periphery of the respective device, by applying reflective material to selected areas of the sheet; (2) forming cut lines around selected edges of the plurality of reflectors; (3) forming fold lines associated with the reflectors; and (4) folding the reflectors and attached substrate away from the substrate portion on which the device is mounted, to form a coupler whose interior is reflective and that is substantially closed around a main axis of light propagation into or from the respective device.
