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 red-color fluorescent substance film 3 giving off maximum emission and linear emission in a wave length ragne 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 Cd and Zn are confined. The following conditions are set up; 7≤WL(πDL)≤14, 0.002≤mCd+mZn≤2, and 0.5≤mHg≤20, (where mHg, mCd, and mZn are, respectively, the amounts (mg/cc) to be confined of mercury, Zn, and Cd per the unit volume of the luminous tube 4, WL(W) is input power, D(cm) is the inside diameter of the luminous tube 4, and L(cm) of the distance between electrodes. Thus, the color rendering property can be raised and stabilized lamp characteristics can be obtained, and also lighting can be made by the usual type high-pressure mercury vapor lamp stabilizer.
