Abstract
An illuminating module is adapted for use in a display apparatus, and includes first and second reflectors, and an omnidirectional light source. The first reflector has a hemispherical first reflecting surface and a first focal point. The second reflector has a curved second reflecting surface that faces the first reflecting surface, and a second focal point that is coincident with the first focal point. The light source is coincident with the first and second focal points. A first portion of light rays from the light source radiates toward the second reflecting surface, and is reflected by the second reflecting surface to travel along an optical axis. A second portion of the light rays from the light source initially radiates toward the first reflecting surface, and is subsequently reflected by the first reflecting surface back to the light source so as to combine with the first portion of the light rays.
