Abstract:
Disclosed is a fluorescent lamp having ceramic-glass composite electrodes, which has a higher dielectric constant, higher secondary electron emission, and higher polarization under the same electric field, and thus enables the movement of many more electrons and cations, resulting in high brightness. The fluorescent lamp having ceramic-glass composite electrodes includes a glass tube, which has a phosphor applied on the inner surface thereof and is filled with a mixture of inert gas and metal vapor, both ends of which are sealed; and hollow cylindrical electrodes provided at both ends of the glass tube, each of the hollow cylindrical electrodes having a stepped portion between a central portion thereof and an end portion thereof, and being formed of a ceramic-glass composite. As the material for the electrode, a composite, including a CaO—MgO—SrO—ZrO2—TiO2 ceramic composition and glass frit, is used.
