Abstract

A light filament of the present invention includes carbon nanotube yarns and two electrodes. The carbon nanotube yarns are wound between the two electrodes. The light filament is characterized by a high surface area to volume ratio, a negative resistivity/temperature coefficient, high mechanical strength and durability at elevated temperatures. Accordingly, power consumption of the light filament is low at incandescent operating temperatures than conventional metallic filaments. A method for making the light filament includes the steps of: forming an array of carbon nanotubes; pulling out carbon nanotube yarns from the carbon nanotube array; and winding a plurality of the yarns between two electrodes to form the light filament.
