Abstract

PURPOSE:To obtain a miniature luminous source of high efficiency for photo- setting by sealing indium halide together with mercury and rare gas in a lumi nous tube so as to be highly luminous in the useful range of photo-setting wave length for a photo-setting resin even with no filter. CONSTITUTION:Indium halide is sealed in a luminous tube together with mercury and rare gas. For instance, a subminiature metal halide lamp of 40W having electrodes can be obtained by sealing in a luminous tube 1 made of quartz a small quantity of indium halide such as InI3, mercury and rare gas 4. Thereby the fraction of the emitted energy in the spectrum range of 400-500 nm, the useful range of photo-setting wave length for a photo-setting resin, to the lamp input can be made larger than that of a halogen lamp to improve the utility efficiency significantly.
