Abstract

A light source comprises a matrix of micro-filaments able to emit light by incandescence when powered by an electrical current. According to the invention, on the matrix electrical and / or mechanical connections are obtained by means of agglomerations of carbon nanotubes at least partially ordered with respect to each other.

Description

[0001] This is a divisional of application Ser. No. 10 / 392,813, filed Mar. 21, 2003, which claims priority to TO2002A000256 filed Mar. 22, 2002, the disclosures of both of which are hereby incorporated by reference in their entirety.BACKGROUND OF THE INVENTION

[0002] The present invention relates to a method for producing an incandescent light source and a light source obtained according to such method.

[0003] The first working step followed for purposes of producing filaments for incandescent light sources typically consists of preparing a mixture of tungsten and metallic additives, which is subsequently sintered in the form of bars.

[0004] The bars thus obtained are then subjected to hammering and drawing with successive passages, until obtaining a continuous wire with the desired diameter; said wire is subsequently wound in a spiral and cut to the required length to be ready, after a stabilising heat treatment, to be mounted onto a respective support to be inserted in the light s...
