Abstract
PURPOSE: To simplify the process of manufacturing ultrared-ray absorbing incandescent lamps and to improve reliability of their performance, by admixing iron component as ultrared-ray shielding means directly into raw material of glass which forms the outer structure of lamp, thereby omitting the procedure of forming ultrared-ray absorbing film after the outer structure of lamp is shaped.
