Abstract

PURPOSE: To improve color-rendering property and life characteristics by using a light-permeable alumina as the material for luminous tube and also by adding and enclosing a metal, e.g., cadmium, etc., in addition to mercury as a luminous substance, and a rare gas as a start-up gas.
CONSTITUTION: The luminous tube 1, consisting of a light-permeable alumina tube, has the cells 2 and 3 sealed at its both ends, and the cells 2 and 3 are connected with the niobium tubes 4 and 5 sealed to the caps 6 and 7 of the same material as that of the luminous tube 1 with the adhesive cements 15W18. And, the caps 6 and 7 are sealed to both ends of the luminous tube 1 with the cements 15W18 alike. A start-up rare gas and a luminous metal, e.g., cadmium, zinc, etc., in addition to mercury are enclosed in the luminous tube 1. Thus, because the alumina tube 1 is chemically stable and thus does not react with such added metal as cadmium, zinc, etc., color-rendering property can be improved and life characteristics can be also improve.
