Abstract
A lighting engine, system and method of fabrication are described. The system contains a flexible printed circuit (FPC) shaped as a loop. LEDs are mounted on the FPC to emit light toward a center of the loop. A light guide positioned in an interior of the loop receives light emitted by the LEDs through an edge of the light guide. The light guide has slots formed therein that receive locator pins to limit thermal displacement of the light guide towards the LEDs. Other apparatuses, systems, and methods are also disclosed.
