Abstract: A backlight is disclosed and includes a visible light transmissive body primarily propagating light by TIR with a light input surface and a light output surface and a light guide portion and a light input portion. The light guide portion has a light reflection surface and a light emission surface. The light input portion has opposing side surfaces that are not parallel. One of the opposing surfaces is co-planar with either the light emission surface or the light reflection surface. A light source is disposed adjacent to the light input surface. The light source emits light into the light input portion. A reflective layer is disposed adjacent to or on the opposing side surfaces.

Abstract: A projection subsystem includes a light engine that provides a collection lens, a collimator and at least one solid state light emitter. A projection lens assembly receives the image and provides a projection beam having a luminous flux level. The projection subsystem has a portability efficacy.
