    摘要： A light source module is provided comprising an emitter having at least one light emitting surface and an at least partially hollow integrating optic mounted over the emitting surface; where the index of refraction within the hollowed area is less then the index of the subsequent medium along the optical path. The integrating optic has a proximal end facing the emitting surface and a distal end facing away from the emitting surface. The distal end of the integrating optic is flat and has a rectangular aspect ratio which can differ from the aspect ratio of the emitter. One or more optical films and/or an optical component such as a collection lens can be adhered to the distal end of the integrating optic.

    摘要： A focusing unit includes a Fresnel lens combination, where the Fresnel lenses are oriented to reduce shadowing losses. Shadowing is a scattering of light from reflection at the facet walls that separate adjacent Fresnel zones on a given Fresnel lens. Two substantially adjacent Fresnel lenses make up the focusing unit, which can be used as a condenser that collects light from a source in a projection system. Both Fresnel lenses have non-faceted sides that face the light source. The first Fresnel lens collimates the light from the source. The second Fresnel lens receives the collimated beam, with a range of incident angles determined by the spatial extent of the source. Components such as reflective polarizers and anti-reflection coatings can be used between the Fresnel lenses and can be applied to the non-faceted side of the second Fresnel lens.

    摘要： 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.

    摘要： A projection system having a prescribed relationship between the condenser and the projection lens is disclosed, where an imager gate normally coinciding with a projection object plane is between and spaced away from a condenser back focal plane and a condenser image plane. The condenser images an extended source onto the condenser image plane. A pixilated panel or film defining a graphic image is located at the imager gate. The magnification of the condenser is chosen so the image of the source is essentially the same size as the pixilated panel. Positioning the imager gate away from the condenser image plane provides blurring of any brightness non-uniformities across the area of the source, providing a relatively uniform illumination pattern whose outer shape matches the shape of the imager gate.
