Patent ID: 7800293

Claim:
A field emission lamp comprising: a transparent tube having at least one open end; at least one sealing member, a respective sealing member being assembled in a corresponding open end of the tube; an anode comprising an anode conductive layer, a fluorescent layer, and at least one anode electrode, the anode conductive layer being formed on an inner surface of the tube, the fluorescent layer being created on a portion of a surface of the anode conductive layer, the at least one anode electrode electrically connecting with the anode conductive layer and extending out of the at least one sealing member to form at least one anode outer electrode; and a cathode comprising an electron emission element and at least one cathode electrode, the electron emission element being disposed in the tube, the at least one cathode electrode being disposed on and electrically connecting with at least one end of the electron emission element and extending out of the at least one sealing member to provide at least one cathode outer electrode, the electron emission element comprising an electron emission layer, the electron emission layer comprising a glass matrix and a plurality of carbon nanotubes, getter powders, and metallic conductive particles dispersed therein.
