Abstract
PURPOSE:To obtain a discharge lamp with a high efficiency and a long life by coagulating unvaporized metal and metal hologenide on the inner wall of a container under a rated discharge condition in a discharge container without providing a heater on the circumference of the outer wall of a luminous tube end. CONSTITUTION:Unvaporized metal and metal halogenide can serve a function as a heater. Therefore, a screening effect of visible rays radiated from an arc can be suppressed to a minimum at the end of a luminous tube 1. Since the end of the luminous tube 1 is not heated compulsively from outside, the unvaporized materials are distributed and coagulated continuously and smoothly from a low temperature section to a high temperature section of the inner end wall of the luminous tube 1 depending on the temperature distribution of the luminous tube 1 and their vapor pressures. Accordingly, a desired vapor density is realized easily, and a high efficiency and a long life of the discharge lamp are attained.
