Glow discharge lamp, lighting equipment and glow discharge lamp for electrode

摘要

PROBLEM TO BE SOLVED: To provide a glow discharge lamp such as a glow starter essentially improving spattering of an electrode activator and improving starting characteristics under a dark place condition by shortening lighting required time and lighting equipment using it.;SOLUTION: This glow charge lamp is furnished with an discharge container 1, a pair of electrodes 2, 3, an discharge medium and an electron emission material 4 made of zinc alloy supported at least by the one 3 of a pair of the electrodes 2, 3. It is possible to use, for example, zinc - nickel alloy as the zinc alloy. In this case, 2-15 mass % is within a favorable range of the contents of nickel. The zinc alloy to be used as the electron emission material 4 raises its melting point in comparison with zinc, its dissipation due to spattering is restrained, and accordingly, electric discharge starting time is shortened for a longevity guaranteeing period, and as gas emission is reduced, rise of electric discharge starting voltage is extremely small.;COPYRIGHT: (C)2003,JPO
