Abstract

PURPOSE: To improve the brightness and uniformity of a metallic vapor discharge lamp by reducing the thickness of light emitting tube wall of high heat and corrosion resistance material such as, for example, permeable ceramics or metal oxide monocrystal to thereby lower the starting voltage of the lamp so that the lamp may exactly be started to the end of its life.
