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.
