  • Publication number: 20090096958
    Abstract: A cold cathode fluorescent lamp includes a glass bulb (16), a protective film (22) formed on an inner face of the glass bulb, and a phosphor layer (24) that overlaps the protective film and that contains blue phosphor particles (26B), green phosphor particles (26) and red phosphor particles (26). The glass bulb has been formed from soda glass, and the blue phosphor particles have been coated with a metal oxide (30). Also, the protective film is made of silica (SiO2). Since the protective film has been provided in the fluorescent lamp and since the blue phosphor particles, which readily deteriorate, have been coated with the metal oxide, a good luminance maintenance rate is obtained. In addition, although the glass bulb of the fluorescent lamp is made of soda glass, since the protective film is made of silica, the fluorescent lamp obtains an initial luminance equivalent to the initial luminance of a fluorescent lamp whose glass bulb is made of borosilicate glass.
