| Title: |
Heat Distributing Hybrid Reflector Lamp or Illumination System |
| Abstract: |
A reflector lamp or illumination system comprising a concave reflector
having a parabolic or ellipsoidal front section and a spherical rear
section with it's focal point just ahead of the focal point of the front
section, and a finite light source located at the focal point of the
front section. The reflector sections are dimensioned so that light rays
from the finite light source which are reflected by the spherical rear
section become re-reflected by the front section and distributed more
evenly in said projected beam pattern with the energy rays filling back
in from the edge to the center. Additionally the light rays, re-reflected
by the front section, are made up of uncompressed light and energy
components which provide a beam pattern which is substantially more even
in light and energy distribution, does not have compressed light and
energy producing hot spots of light and heat at the center of the
projected beam pattern or gate, and is therefore less harmful to parts
such as lighting fixture parts, plastic lens and items being projected
such as plastic color media, film, and slides.
