    摘要: An illumination system including a light source, a light guide including an output surface, emissive material positioned to receive light from the output surface of the light guide, and an interference reflector positioned such that the emissive material is between the output surface of the light guide and the interference reflector is disclosed. The light source emits light having a first optical characteristic. The emissive material emits light having a second optical characteristic when illuminated with light having the first optical characteristic. The interference reflector substantially transmits light having the second optical characteristic and substantially reflects light having the first optical characteristic.

    摘要: A LED package including an LED that emits excitation light at an excitation light wavelength and a layer of phosphor material positioned to receive the excitation light and having a first index of refraction at the excitation light wavelength. The phosphor material emits visible light at a visible light wavelength when illuminated with the excitation light. An interference reflector is positioned adjacent to the layer of phosphor material and a TIR promoting layer is in contact with the layer of phosphor material. The TIR promoting layer has a second index of refraction at the excitation light wavelength that is less than the first index of refraction at the excitation light wavelength.

    摘要: A head-up display includes a projection system and a window having a target area where a reflective polarizer is positioned to reflect light from the projection system to a viewing area. Light from the projection system is p-polarized and strikes exposed window surface(s) at an acute angle to reduce or eliminate multiple or “ghost” images. The acute angle is closely matched to a Brewster angle of the exposed window surface(s). The reflective polarizer includes a multilayer stack with refractive indices of individual layers chosen to reflect p-polarized light substantially more than s-polarized light over a wide angular range that includes the acute angle. The reflective polarizer also can reflect infrared light to reduce cabin heating from solar radiation.

    摘要: A transparent multilayer device which reflects light in the infrared region of the spectrum while transmitting light in the visible region of the spectrum. The device comprises a multilayered polymer film and a transparent conductor. The multilayered polymer film preferably comprises layers of a semi-crystalline naphthalene dicarboxylic acid polyester having an average thickness of not more than 0.5 microns and layers of a second polymer having an average thickness of not more than 0.5 microns. The layers of semi-crystalline naphthalene dicarboxylic acid polyester preferably have a positive stress optical coefficient. The transparent conductor comprises at least one layer containing a metal or a metal compound in which the metal compound is preferably selected from the group consisting of metal oxides, metal alloys, and combinations thereof. Silver and indium tin oxide are particularly preferred transparent conductors. The transparent multilayer devices may be applied to the surface of a glass or plastic substrate, such as an exterior window in a building, or to a windshield or window in an automobile, truck, or aircraft.

    摘要: The present invention provides reflective films and other optical bodies which exhibit sharp bandedges on one or both sides of the main reflection bands. The optical bodies comprise multilayer stacks M.sub.1 and M.sub.2, each having first order reflections in a desired part of the spectrum and comprising optical repeating units R.sub.1 and R.sub.2, respectively. At least one of the optical repeating units R.sub.1 and R.sub.2 varies monotonically in optical thickness along the thickness of the associated multilayer stack.
