Abstract
An illuminating module is adapted for use in a display apparatus, and includes a spherical first reflector segment having a first reflecting surface and a first focal point. A parabolic second reflector segments has a second reflecting surface facing the first reflecting surface in a first direction, and a second focal point that is coincident with the first focal point. A light source is coincident with the first and second focal points. Light rays that radiate toward the second reflecting surface are reflected thereby to travel in a second direction transverse to the first direction. Light rays that radiate toward the first reflecting surface are reflected thereby back to the light source. A third reflector segment has a third reflecting surface facing the second reflecting surface in the second direction to reflect the light rays received thereby to travel in a third direction transverse to the second direction.
