Title (EN) INCANDESCENT ELECTRIC LAMP WITH ETALON TYPE TRANSPARENT HEAT MIRROR
(FR) LAMPE ELECTRIQUE A INCANDESCENCE AVEC MIROIR DE CHALEUR TRANSPARENT
Abstract: front page image
(EN)An incandescent lamp utilizing an etalon type transparent heat mirror (11, 13) on the lamp envelope (40) for transmitting radiation in the visible range produced by the lamp filament and reflecting infrared thermal radiation back to the filament for increasing its temperature and thereby increasing its efficiency.
(FR)La lampe comprend un miroir de chaleur (11, 13) transparent sur l"enveloppe (40) de la lampe afin de transmettre la radiation du domaine visible produit par le filament et de reflechir vers le filament la radiation thermique infrarouge. Ainsi la temperature du filament et par consequent son efficacite sont augmentees.
