Abstract

PURPOSE:To provide a high-pressure mercury vapor fluorescent lamp, in which a composite layer of fluorescent material and material for scattering both of visible and ultraviolet rays is applied on the inner surface of outer bulb, so as to improve efficiency of converting ultraviolet rays into visible rays. CONSTITUTION:Liquid dispersed with fine powder consisting of at least one of SiO2, Al2O3, SnO2, MgF2, MgO and BaSO4 is introduced into the lamp and baked on the inner surface of outer bulb 2, thereby forming a scattering layer 5 for scattering layer 5 for scattering both of visible rays and ultraviolet rays in the region of 200-400nm. Further, liquid dispersed with fluorescent material for improving light emitting and coloring performance is coated on the layer 5 and baked to form fluorescent layer 3. Thus, a lamp having a high efficiency of emitting visible rays cab be manufactured, with visible-ray transmitting factor of scattering layer 5 adjusted at 80-95% and that of the fluorescent layer 3 adjusted at 65-90%.
