摘要： A light collector which includes a light pipe having a face with a center and a diameter. The light pipe also has a predetermined acceptance angle. The light source is located a predetermined distance from the light pipe positioned on a line perpendicular to the center of the face of the light pipe. A concave surface defined by a plurality of ellipsoidal sections having a common first focus and a common second focus is used to reflect light from the light source to the light pipe. The ellipsoidal section have decreasing eccentricities with increasing object angle along the concave surface. The light source is located substantially at the first focus of the plurality of ellipsoidal sections and the center of the face of the light pipe is located substantially at the second focus. The surface has an eccentricity such that light rays emitted from the light source reflected by the surface to the light pipe do not exceed the acceptance angle of the light pipe.

摘要： An illumination system includes a plurality of radiation generating sources, such as LED dies. A corresponding plurality of optical waveguides is also provided, with each waveguide having a first and a second end, with each first end being in optical communication with the corresponding LED die. An array of corresponding passive optical elements is interposed between the plurality of LED dies and the corresponding first ends of the plurality of optical waveguides. The illumination system provides for substantially high light coupling efficiency and an incoherent light output that can appear to the human observer as arising from a single point of light. In addition, the light can be output remotely at one or more locations and in one or more directions.
