  • Patent number: 4585300
    Abstract: A multi-emitter semiconductor electroluminescent device includes a stud having a mounting block on a surface thereof and a cover extending over the mounting block and secured to the stud. The mounting block has a plurality of surfaces which are angled toward a common point. A separate electroluminescent semiconductor element is mounted on each of the surfaces of the stud and have light emitting surfaces which face toward the common point. The electroluminescent elements are electrically connected to lead wires so that they can be operated either individually or simultaneously. An optical fiber extends through the cover and has one end directly over the common point so that the light emitted from all of the electroluminescent elements will enter the end of the optical fiber and propagate along the fiber.

  • Patent number: 4479698
    Abstract: A light emitting assembly comprising a light emitting device, an optical fiber and an optical coupling medium which is contacted to both a facet of the light emitting device and an end face of the fiber and whose maximum diameter is comparable to the diameter of the end face of the fiber. The invention is also a method of making this light emitting assembly which comprises positioning the end face of the optical fiber adjacent to the emitting portion of the facet, interposing an optical coupling medium between the facet and the end face of the fiber and increasing the space between the facet and the end face of the fiber until the maximum amount of light is coupled into the fiber.
