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.
Claims19
A method for producing a light source comprising a complex of micro-filaments able to emit light by incandescence when powered by an electrical current, the method comprising the steps of:
- forming the complex of micro-filaments by a first material, and
- achieving on the complex of micro-filaments one or more electrical and/or mechanical connections using a second material,
- wherein the connection or connections are obtained using an agglomeration of carbon nanotubes at least partially ordered with respect to each other.
