Abstract

PURPOSE: To achieve a low color temperature and good color rendering at the same time and extend an estimated service life by specifying the mol ratio of sodium halide to rare earth metal halide. CONSTITUTION: One or more rare gas as a starting gas, mercury as a buffer gas and additives such as dysprosium, holmium, sodium halide or thallium, cesium and/or lithium halide are filled in a container 1. The discharge container 1 is stored in a light-transmissive envelope 2, and conductors 10, 10' extending to electrodes 3, 3' are pulled form the end of the envelope. In this case, the total mol ratio of dysprosium and holmium halide to sodium halide extends from 1:1 to 1:4. A metal halide filled in a discharge tube is metal iodide additive. In this way, a metal halide lamp with a low color temperature and good color rendering, as well as a long service life, is obtained.
