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 film on the inner wall of outside tube and confining mercury and any one or both of Zn and Cd in luminous tube.
CONSTITUTION: The luminescent film 3 containing a red-color fluorescent substance evolving a maximum emission in a wave length range from 610nmW630nm is provided on the inner wall of the outside tube 1, and in the luminous tube 4, mercury and any one or both of Zn and Cd are confined. The kind of the red-color fluorescent substance used is preferably a trivalent Eu-activated yttrium (Y) vanadate, for example. Thus, the color-rendering property can be raised by the synergistic action of emission spectra resulting from the vapor discharge of the Zn and Cd metals confined in the luminous tube 4 and the emission from the fluorescent substance and also lighting can be made possible by the usual type high-pressure mercury vapor lamp stabilizer.
