Abstract

PURPOSE:To improve the efficiency and the color spectrum by providing a heating member at the end in a light emission tube. CONSTITUTION:Predetermined amount of mercury halide and proper amount of start assistant gas or argon are sealed in a silicon light emitting tube 1 of metal halide lamp where main electrodes 2, 3 are arranged at both ends while a filament 5 comprised of tungsten is connected to the main electrode 3. The main electrode 2 is connected through a lead 8 to a lighting device 12. The filament 5 connected to the main electrode 3 is connected through a lead 9 to the lighting device 12.
