A field emission lamp ( 30 ) includes a tube ( 31 ) having a closed end and an open end, an encapsulation board ( 38 ) mated with the open end, an anode layer ( 32 ) formed on an inner surface, a fluorescence layer ( 33 ) formed on the anode layer, a cathode down-lead pole ( 342 ) located at the encapsulation board, a cathode fixing pole ( 341 ) located at the closed end, a cathode filament ( 34 ) 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 ( 321 ) located at the anode layer near the open end, and an anode down-lead pole ( 322 ) 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.
