Abstract

PURPOSE:To improve the light emission efficiency by coating a fluorescent material mainly composed of halo-phosphate fluorescent material mixed by specific amount with a fluorescent material which emits ultraviolet ray having wavelength of 365nm. CONSTITUTION:A fluorescent material mainly composed of halo-phosphate calcium and mixed with less than 3wt% of fluorescent material which emits ultraviolet ray having the wavelength of 365nm is coated on the inner face of a fluorescent lamp. Consequently, the ultraviolet ray produced in the bulb can be utilized effectively including that having the wavelength of 365nm, thereby the light emission efficiency can be improved.
