Abstract
A field emission lamp () includes a tube () having a closed end and an open end, an encapsulation board () mated with the open end, an anode layer () formed on an inner surface, a fluorescence layer () formed on the anode layer, a cathode down-lead pole () located at the encapsulation board, a cathode fixing pole () located at the closed end, a cathode filament () having a carbon nanotube layer formed on a surface thereof fixed between the cathode down-lead pole and the cathode fixing pole, an anode down-lead ring () located at the anode layer near the open end, and an anode down-lead pole () located at the encapsulation board and electrically connected with the anode down-lead ring. The field emission lamp has a simple structure, thereby having an enhanced production rate and a reduced cost.
