Abstract
A light source such as a semiconductor light emitting diode is positioned in a first opening in a transparent member, which may function as a waveguide in a display. The transparent member surrounds the light source. No light source is positioned in a second opening in the transparent member. In some embodiments, the first opening is shaped to direct light into the transparent member. In some embodiments, a reflector is positioned over the light source. The reflector includes a flat portion and a shaped portion. The shaped portion extends from the flat portion toward the light source.
