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.
