ABSTRACT:
The incandescent lamp is equipped with a luminous element which is hermetically inserted in a bulb together with a filling, the luminous element having a metal carbide whose melting point is above that of tungsten. The supply lead is fabricated integrally with the luminous element from a wire and provided with an electrically conducting coating which decisively improves the impact strength and make-proofness.
