Abstract

PURPOSE: To improve sodium emission without increasing the thermal wall load and to promote high efficiency by sealing halogenated zinc in a luminous tube.
CONSTITUTION: Starting rare gas, such as mercury, argon gas, etc., one kind of halogen, such as iodine, chlorine, etc., and sealing metals containing sodium metal are sealed in a luminous tube and halogenated zinc is mixed in these sealing metals. That is, for example, in a discharge lamp in which sodium iodide and mercury are sealed, the efficiency is low and color temperature is comparatively high. By adding and sealing zinc chloride, however, the efficiency increases, the color temperature is also lowered, and sodium emission can be improved. By also mixing halogenated thallium, higher efficiency white light can be obtained.
