The town filament is a linear spiral shape, and tungsten The two ends of the wire are respectively connected with the support ring and the support ring is respectively connected with the sealing portion. The circumstance ring is used for I to support the lamp 4, and the sealing part ensures that the filament is energized without leaking gas (inert gas = in the process of making the surface heat source, it is necessary to have many positions of the crane wire = a uniform The illuminating surface or the filature is processed into a large piece.
