ABSTRACT:
LEDs are mounted onto a flat, thermally conductive, substrate, which is folded to form a light recycling cavity. A planar substrate is first coated with a metal layer, which is patterned to electrically connect the LEDs and to form bonding pads for wirebonds to connect the LEDs to external circuitry. The LEDs are mounted on the substrate. The substrate is then scribed on the backside to form the folds. The LED dies are then attached onto the metal islands (pads) defined on the substrate and wirebonds are used to connect the top side of the LED to adjacent patterned metal islands (pads) on the substrate. The substrate is then folded into a light recycling cavity where the LEDs are facing the inside of the cavity.
