ABSTRACT:
A cold cathode fluorescent lamp includes a light-emitting tube made from borosilicate glass doped with 5.1–9.0 wt % of an ultraviolet light absorbent, the light-emitting tube having phosphors coated on an inner surface thereof, and mercury and a rare gas enclosed therein. As a result, 313 nm UV light in addition to 254 nm UV light is sufficiently blocked, thus enabling the provision of cost-effective CCFLs that do not readily cause a reduction in the surface brightness of backlight units.
