Abstract
The invention is related to a reflector lamp comprising a parabolic primary reflecting section, a parabolic or spheric secondary reflecting section joined to the primary reflecting section, a parabolic or spheric tertiary reflecting section joined to the secondary reflecting section, and an incandescent or discharge light source. The secondary and tertiary reflecting sections have faceted surfaces which longitudinally extend along the surface thereof so that most (at least 50%) or substantially all the light reflected by the faceted surfaces avoids the light source and thus the light, which would be absorbed or scattered by the light source, is minimized or substantially eliminated.
