Abstract:
An arc discharge lamp includes a light transmissive envelope (3), two electrodes (1, 2) disposed at least partially inside the light transmissive envelope, and a plasma forming fill which includes selenium when excited disposed inside the light transmissive envelope (3). The exterior surfaces of the part of the electrodes (1, 2) disposed inside the light transmissive envelope (3) comprise an electrode material selected from the group of molybdenum and molybdenum compounds.

Abstract:
Various lamp systems are disclosed which effectively utilize light from an aperture lamp (3). Lamp systems are respectively configured to perform various types of light recapture including etendue recycling, polarization recycling, and/or color recycling. Various novel optical elements are disclosed including an electrodeless light bulb (5) with an integral lens (9), a molded quartz ball lens with an integral flange, a molded quartz CPC with an integral flange, a truncated CPC, and a segmented CPC. Various novel optical systems are disclosed including systems which perform angle selection and/or etendue selection.
Abstract:
A light pipe (4) includes a conduit (6) configured to receive light at one end and to distribute the light along its length. The conduit (6) includes a combination of specular and diffuse reflecting surfaces (8) arranged to pass a portion of the light down the light pipe (4) primarily with specular reflection and to emit a portion of the light out of the light pipe (4) primarily with diffuse reflection. The reflecting surfaces (8) are substantially parallel to a longitudinal axis of the light pipe (4). A plurality of conduit (8) may be used to control the light distribution characteristics of the light pipe (4). The conduit (6) may be made from inexpensive plastic sheet materials.
