MANUFACTURE JIG OF FIELD EMISSION TYPE ILLUMINATION LAMP

PROBLEM TO BE SOLVED: To provide a jig capable of being effectively utilized for manufacturing a field emission type illumination lamp by bridging a cathode line in the air and vacuum-sealing it in the center of a thin and long glass tube with a small diameter, without contacting a phosphor of an inner peripheral surface. SOLUTION: The jig is for manufacturing a field emission type illumination lamp equipped with an anode on an inner surface and with a cathode line 5 for field emission bridged along the center of a glass tube 1 equipped with a phosphor on the anode. A glass tube holder 22 with a glass tube mounting hole 25 having a stage for inserting an end part of the glass tube 1 to a predetermined position penetrated and formed, a sealing means adhered to an outer periphery of the inserted glass tube 1, a core-extraction retaining means for inserting the anode line 5 and pinching it concentrically with the glass tube mounting hole 25, and an aeration hole 33 communicating to the glass tube mounting hole 25, are mounted into a housing 11.
