ABSTRACT:
A light filament (206) formed from carbon nanotubes is characterized by high mechanical strength and durability at elevated temperatures, a high surface area to volume ratio, and high emissivity. Additionally, electrical resistance of the light filament does not increase with increasing temperature as much as electrical resistance of conventional metallic light filaments. Accordingly, power consumption of the light filament is low at incandescent operating temperatures.
