SEALING STRUCTURE OF DISCHARGE LAMP, AND DISCHARGE LAMP INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2018037320
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sealing structure of discharge lamp capable of feeding a larger lighting current than that of conventional discharge lamp.SOLUTION: A sealing structure is constituted of a luminous tube 12, an electrode support rod 38, an electrode side power distribution plate 18, an external lead rod 20, an outer side distribution plate 22, a glass member 24 fusing with the inner surface of a sealing part 34, and an electrification member 26 for connecting the electrode side power distribution plate 18 and the outer side distribution plate 22 electrically. The electrification member 26 is constituted of at least a second electrification material 63, and a first electrification material 62 disposed closer to the center side of the sealing part 34 than the second electrification material 63, so as not to come into direct contact with the second electrification material 63 between the electrode side power distribution plate 18 and outer side distribution plate 22. The glass member 24 is constituted of at least a second glass material 49 disposed between the first electrification material 62 and second electrification material 63, and a first glass material 48 disposed closer to the center side of the sealing part 34 than the first electrification material 62. With such an arrangement, above-mentioned problem can be solved.SELECTED DRAWING: Figure 3
