Abstract

PURPOSE: To permit lighting with high-pressure mercury vapor lamp stabilizer by improvement of the start-up characteristics of lamp with short inter-the main electrode distance by confining mercury, a metal halide, and neon and argon in luminous tube with a specific pressure.
CONSTITUTION: In the luminous tube 1 in which the distance between the main electrodes 2a and 2b is set up to 25W15mm, mercury, a metal halide, and a Ne-Ar mixed gas of a pressure of 60W300 Torr are confined. For example, in the luminous tube 1 10mm in inside diameter, in which the distance between the main electrodes 2a and 2b is 20mm, 20mg of mercury, 20mg of NaI, 5mg of ScI3, and a Ne-Ar (0.5%) mixed rare gas of a pressure of 60W300 Torr are confined, and then the luminous tube 1 is supported in the inside of the outside tube 16 to make up a metal halide lamp. Thus, the start-up characteristics of the short inter-main electrode distance- type metal halide lamp can be improved and lighting is made possible by the usual type high-pressure mercury vapor lamp stabilizer.
