Abstract

PURPOSE: To permit lighting with high-pressure mercury vapor lamp stabilizer as well as raise color-rendering property by providing a red-color fluorescent substance film on the inner wall of outside tube and confining specific amounts of mercury and any one or both of Zn and Cd in luminous tube.
CONSTITUTION: The luminescent substance film 3 containing a red-color fluoresent substance giving off a miximum emission in a wave length range 610nmW630nm is provided on the inner wall of the outside tube 1, and in the luminous tube 4, mercury, any one or both of Zn and Cd, and a halogen in a proportion of 0.7×10-6gr atom per 1cc of the luminous tube 4 are confined. The kind of the red-color fluorescent substance used is a trivalent Eu-activated yttrium (Y) vanadate, etc., preferably. Thus, the color-rendering property can be raised and the lowering of flux-maintaining rate and the cracking of luminous tube during its life span can be prevented, and also lighting can be made by the usual type high-pressure mercury vapor lamp stabilizer.
