Abstract

PURPOSE:To reduce the variation of the colour of lamp light during life by sealing- in scandium and thorium in which at least thorium is in the form of iodide. CONSTITUTION:In a luminous bulb 1 made of quartz glass, electrodes 2, 2 and an auxiliary electrode 3 are arranged. In the luminous bulb 1, scandium, thorium, sodium, iodine, mercury, and rare gas for starting are sealed. Scandium and thorium are sealed in which at least thorium is sealed in the form of iodide. Such a luminous bulb 1 is accomodated in an outer bulb, and completed as metal halide lamp.
