Abstract
PURPOSE: To improve the efficiency, color display property and durability of a lamp by controlling the quantity of a metal halide enclosed in a lamp tube at a specific value determined in relationship with the lamp input power rate.
CONSTITUTION: Main electrodes 2 and 2 are sealed in a light transmittable and heat-resisting tube 1, such as a quartz tube, opposite to each other and at a distance between them. An auxiliary starting electrode 3 is provided adjacently to one of the main electrodes 2 to facilitate the start of the lamp. Each end of conductive metal foils 5 is connected with each stem 4 of the electrodes 2, 2 and 3 and each of the other ends of the conductive metal foils 5 is connected to an electric wire 6. Each sealed end of the light transmittable tube 1 is covered with a heat insulating covering 7 for keeping warm. The specific quantity of scandium iodide M mg/cc of the interior volume of the lamp tube 1 relative to the lamp input rate (W) is defined by; 1.10×e-2.50×1000W<M<1.21×e-9.5×10000W and the weight ratio of natrium iodide enclosed in the tube 1 to the scandium iodide enclosed in the tube 1 is between 3W9.
