DIELECTRIC BARRIER DISCHARGE LAMP AND LIGHTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a dielectric barrier discharge lamp with a long life. SOLUTION: The dielectric barrier discharge lamp is provided with ceramics 2 provided with a concave portion having no angles smaller than a right angle which are utilized as an electrode. As a result, an electric field concentration during discharging is controlled to give a long life to the lamp. COPYRIGHT: (C)2009,JPO&INPIT
