| Title: |
Incandescent Illumination System Incorporating an Infrared-Reflective Shroud |
| Abstract: |
An improved incandescent lamp and incandescent lighting system are
disclosed, for projecting a beam of light with substantially improved
energy efficiency. The incandescent lamp includes a pair of reflective
ceramic filament supports for supporting one or more filaments in
prescribed position(s) within an envelope while reflecting back
substantially all visible and infrared light for incorporation into the
projected beam or for absorption by the filament(s). The incandescent
lighting system includes a special infrared-reflective shroud
concentrically encircling the incandescent lamp, for reflecting infrared
light back toward the lamp filament(s) while transmitting visible light
to a concave reflector for incorporation into the projected beam. The
infrared-reflective coating is deposited onto the shroud's inner surface,
and it includes a dielectric coating and an underlying transparent
conductive coating. The lamp and the shroud are separately mounted
relative to the concave reflector and are configured such that the lamp
is removable without requiring removal of the shroud.
