Abstract

Improvements introduced in a silver-plated incandescent lamp characterized in that at least a part of the bulb carrying the silver cap has a shape such that rays coming from a point of the filament and falling on said cap undergo at least two reflections before reaching the bushing, also suffering from the light emitted by the filament smaller losses than in the known lamps.
