Abstract: Pixels for a large video display which employs solid-state emitters, such as colored light emitting diodes, as light source are formed by outfitting each colored solid state emitter within the pixel with an individually tailored miniature intensity-enhancing optical system. Each of these miniature optical systems comprises a set of four wide field-of-view Lambertian reflectors 34, a pair of narrow field-of-view Lambertian reflectors 36, and a beam-shaping lens 38. The miniature intensity-enhancing optical system can be specifically designed to restrict emission in the vertical field-of-view, while providing a Lambertian intensity dependence throughout an unrestricted horizontal view. For example, the field-of-view in the vertical direction may be limited to about null30null while the field-of-view is about null90null in the horizontal direction.

Abstract: The invention relates to an incandescent lamp whose lamp vessel (20) has an interference filter (30) with locally differing layer thickness for producing red light. The interference filter (30) has a second absorber layer and additional layers of low optical refraction and high optical refraction for reducing its transmission in the violet, blue and green spectral regions.

Abstract: A greensheet comprising an inorganic pigment and an inorganic matrix component is applied to a surface of a glass substrate and fired for fixing. The formed shading film has a portion whose thickness is 90% or more of the maximum thickness of the shading film within the range of 0.5 mm from an edge of the shading film. Thus, a shading film that has distinct end faces and has an excellent thickness uniformity can be formed with a good positional accuracy. Therefore, a lamp having a highly precise light distribution property can be obtained. In addition, a lamp having such a property can be obtained with a few steps and at a low cost.
