Abstract

A lighting engine, system and method of fabrication are described. The engine contains a chassis having a side wall and bottom surface that define a cavity. A recess is formed in the bottom surface. A flexible printed circuit (FPC) is on the side wall and LEDs are mounted on the FPC to emit light toward a center of the cavity. A light guide positioned within the cavity receives light emitted by the LEDs through an edge of the light guide. A gasket disposed within the recess is in contact with a first surface of the light guide. A reflector within the cavity is adjacent to a second surface of the light guide opposite the first surface of the light guide. A backplate is attached to the chassis and configured to seal the cavity. Other apparatuses, systems, and methods are also disclosed.
