ABSTRACT:
A light transmission device is provided including a light pipe having two ends, one end being an ellipsoidal-shaped end. A recess is configured within the ellipsoidal-shaped end for reception of a light source that transmits light into the light pipe. The recess includes an interior concave wall, and the light source is at least partially received in the recess to face the interior concave wall via which light is transmitted into the light pipe. The ellipsoidal-shaped end further includes a curved surface configured to facilitate collection of light into the light pipe when the light source is at least partially received in the recess in the ellipsoidal-shaped end. The ellipsoidal-shaped end includes a first focal point and a second focal point, wherein the recess in the ellipsoidal-shaped end intersects the first focal point, and the second focal point is disposed adjacent to or within the light pipe.
