Abstract: |
This invention relates to a field emission cathode and a field emission illumination device applying the cathode, in which, the cathode includes carbon nm tube wires pulled out from a carbon nm tube array and is formed by single carbon nm tube wire or multiple wires winded together or by winding single or multiple wires on a metal bar. Said device includes a cathode and an anode opposite to it and the energy conversion passes through a process of electricity-light only. |
