Abstract

PURPOSE:To make possible an easy use for everyone by coating a fluorescent body having a luminous wavelength zone within a special range inside a bulb made of glass having a particular limit wavelength so as to decrease a harmful function for the skin and the eye, thereby increasing the safety. CONSTITUTION:A bulb is made of a glass having a range of 300nm+ or -5nm of an absorption limit wavelength defined by JIS, for instance, a soft glass such as a sodium-lime glass, magnesia-lime glass or the like. A fluorescent film is formed inside the bulb by coating a fluorescent body having a range of 300-320nm of a luminous peak wavelength, such as a talium invigorated calcium-zinc phosphate thereon with a conventional method. Thus, the harmful function for skin and eye can be decreased and everyone can use it with ease.
