EXTENDED LIFE INCANDESCENT LAMP WITH SELF CONTAINED DIODE AND REFLECTOR ABSTRACT An incandescent lamp is disclosed having an extended operating life with a high operating ef- ficiency in terms of lumens per watt. The lamp incorporates a rectifying diode in series with the filament and the filament has an operating temper- ature less than 2550°C. The reflector is mounted in the neck portion of the lamp for reflecting visible light outwardly through the bulb portion of the envelope and for minimizing convection cur- rents in the base of the lamp. The diode is dis- posed between the reflector and the lamp base.
