Abstract
A method is described for producing a light source comprising 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 an agglomeration of carbon nanotubes at least partially ordered with respect to each other. The matrix can be formed extending a single uninterrupted wire, some segments whereof mutually cross.

Method for producing a light source comprising a complex or matrix of micro-filaments able to emit light by incandescence when powered by an electrical current, the method providing for the achievement on the complex of micro-filaments of one or more electrical and/or mechanical connections, characterised in that the connection or connections are obtained using an agglomeration of carbon nanotubes at least partially ordered with respect to each other.
Light source comprising a complex or matrix of filaments or micro-filaments able to emit light by incandescence when powered by an electrical current, obtained with the method as claimed in one or more of the previous claims.
Method for producing a light source comprising a matrix formed by a plurality of filaments able to emit light by incandescence when powered by an electrical current, characterised in that the matrix is formed extending a single uninterrupted wire constituted by a material chosen among tungsten or tungsten-based metallic alloys along a complex path defined by a plurality of positioning elements positioned remotely from each other, the path being such that segments of the uninterrupted wire that extend from different positioning elements mutually cross.
Light source comprising a complex or matrix of micro-filaments able to emit light by incandescence when powered by an electrical current and one or more electrical and/or mechanical connections, the connection or connections being produced by an agglomeration of carbon nanotubes at least partially ordered or aligned with each other.
