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.
