Abstract

Incandescent lamp of small power and for very low voltage, which has a light bulb that contains a gaseous atmosphere, a spiral-shaped filament and current-carrying wires that cross the light bulb, characterized in that the light bulb is formed by a tube of hard glass, one end of said tube being crushed to form the clamping area, the current carrying wires are made of an electrically conductive material with a coefficient of expansion compatible with the coefficient of expansion of the glass of the bulb in which they are closed hermetically tight and the gaseous atmosphere present in the bulb is at a pressure greater than 5 bar.
