Abstract

PURPOSE:To intend the amendment of the light characteristics of a lamp by providing a zirconium borate having a particular composition inside a light penetrating enclosure mixing with a fluorescent body to prevent the decrease of the brightness of the fluorescent body. CONSTITUTION:A titanium borate composed of rutile type of titanium dioxide and a zirconium borate consisted of fluorite type of zirconium dioxide are added independently or mixingly at a proper amount of ratio to a fluorescent body respectively. The fluorescent film is allowed to coat inside the light penetrating enclosure. Thus, together with absorbing the Na<+> which diffuses from the enclosure, the effects on sticking of the fluorescent body to the enclosure and sticking of the fluorescent particles can be obtained, whereby the decrease of the brightness of the fluorescent body is avoidable and the optical characteristics of the lamp can be amended.
