ABSTRACT:
A method of manufacturing a miniature tipless halogen lamp having a diameter of 1.0 to 4.0 mm, in which an assembly of a pair of lead wires, a bead welded to the lead wires and a filament connected to the lead wires by pressing flat and crimping the inner ends of the lead wires, the assembly is put in a lamp bulb in place to form an unfinished assembly of the components of the miniature tipless halogen lamp, a plurality of such unfinished assemblies are placed in an apparatus including an integral and airtight combination of a holagen gas introducing sealed box and a heat-sealing box, the lamp bulbs of the unfinished assemblies are sealed by being heated with a heat-sealing carbon plate at a position corresponding to the bead, and then unnecessary portions of the lamp bulbs are cut off to complete the miniature tipless halogen lamps. In manufacturing the miniature tipless halogen lamp, any tip for introducing a halogen gas into the lamp bulb need not be formed in the lamp bulb and the lamp bulb can be formed beforehand in a predetermined form. The apparatus is capable of heat-sealing a plurality of the unfinished assemblies at a time.
