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.
