ABSTRACT:
A metal halide lamp apparatus includes a reflecting mirror and a metal halide lamp has a reflecting/thermal insulating film and a frost portion which is partially formed on the lamp outer surface within a predetermined range continued from the reflecting/thermal insulating film. This causes a decrease in an overall illuminance decrease and the attainment of a desired illuminance ratio and prevents the occurrence of irregularity in illuminance and color. In addition, since electrodes are asymmetrically disposed, it is possible to decrease the rate of devitrification of the luminous tube and make an attempt to increase the life of the luminous tube.
