Abstract An incandescent lamp having a transparent heat mirror placed on a major portion of the lamp envelope which transmits on average in excess of about 60% of the energy in the visible range produced by the lamp filament and which reflects back to the fila- ment at least on average in excess of about 60% of the infrared energy over the range that the filament pro- duces. In the preferred embodiment the transparent heat mirror is formed by a layered coating of TiO2/Ag/TiO2 optimized for the operating temperature range of the filament. The envelope is shaped to reflect infrared energy back to the filament and the filament is constructed to optically conform to the shape of the lamp envelope.
