Title:
HIGH-EFFICIENCY CERAMIC LAMP
Document Type and Number:
WIPO Patent Application WO/2011/153795
Kind Code:
A1
Abstract:
A high-efficiency ceramic lamp includes a discharge cavity (18), electrode tubes (15) on the two ends of the discharge cavity and electrode assemblies extending into the discharge cavity through the electrode tubes. The electrode tubes include inner tubes and weld grooves (13). The inner tubes are close to the discharge cavity, and the weld grooves are positioned on the ends of the electrode tubes. The inner diameter of the weld grooves is bigger than the inner tubes. The weld grooves are filled with solders (12) to realize a hermetically tight seal of the discharge cavity. A tungsten mandril (16), a conducting rod (14) and a lead (11) or a conducting tube are connected in sequence to form an electrode assembly. The tungsten mandril extends into the discharge cavity. The conducting rod is positioned in the inner tube, and the outer diameter of the conducting rod is equal to the inner diameter of the inner tube. The lead extending out of the electrode tube though the solder of the weld groove connects to the end of the conducting rod. Or the conducting tube extending out of the electrode tube though the solder of the weld groove connects to the lead.
