GLASS FOR ILLUMINATING MEANS WITH EXTERNAL ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a glass composition in which the total power loss of the illuminating device with an external electrode can be minimized. SOLUTION: In the glass composition for a glass body of an illuminating device with external electrodes, the quotient of loss angle and dielectric constant tanδ/ε' amounts <5.
