Abstract

PURPOSE: To make the promotion of prolongation of the service life, with a sealing efficiency improved and a luminous material prevented from leakage, by means of pressing, with a dead weight contacted, the spherically protruding part provided in the end of closing unit having an electrode engaged and installed to both end opening parts of the luminous tube with the sealing agent interpositioned.
CONSTITUTION: To both end opening parts 1a of a luminous tube 1 of cylindrical shape, is engaged and installed a closing unit 4 having an electrode 3 with a thermally melting sealing agent 2 intermediately placed, and in center portion of the closing unit 4 is constructed la spherically protruding portion 4a. And by the laser light of laser device, when the luminous tube 1 and the sealing agent 2 of the closing unit 4, held being put between within the tightly closed vessel, are thermally welded, a pressing is processed with a dead weight 5 contacted to the spherically protruding part 4a. In this way, the sealing work not only can be smoothly made even for the closing unit 4 rotating together with the luminous tube 1, but a zirconium hydroxide, previously applied to the closing unit 4, can become non-exfoliation, causing a sealing efficiency to be improved with the lunimous material prevented from leakage, thus a prolongation of the service life can be promoted.
