説明

The light emitted from the conventional fluorescent lamps contains a small amount of ultraviolet (UV) radiation, which causes color change or bleaching of the illuminated objects. Thus, in the presence of paintings and printed matters, application is made of the UV-free fluorescent lamps with a UV-absorption layer deposited in-or outside of the glass tube. However, the UV-absorbing materials employed so far have been fast-deteriorating, and made luminous flux or color rendering properties inferior to the lamps without the absorption layer.<BR>By applying outside the tube a solvent-soluble fluororesin containing a UV-absorbing substance, a UV-free fluorescent lamp is obtained without the above mentioned disadvantages.
