Patent number: 8198816Abstract: An extra-high pressure mercury lamp includes an arc tube made of quartz glass. The lamp includes an arc tube portion and sealing portions connected to the arc tube portion, and encloses 0.15 mg/mm3 or more of mercury. A pair of electrodes are disposed face to face in the arc tube. Each electrode has a rod portion and a base end portion. The base end portion of each electrode is embedded in one of the sealing portions. One of the pair of electrodes serves as a cathode and includes a head portion, which has a larger diameter than the rod portion. A cylinder portion is connected to a rear end portion of the head portion. The cylinder portion extends in the axis direction of the electrode and surrounds the rod portion. The cylinder portion has an inner surface separated from the rod portion.Type: GrantFiled: December 17, 2009Date of Patent: June 12, 2012Assignee: Ushio Denki Kabushiki KaishaInventors: Atsushi Imamura, Takashi Yamashita, Tetsu Takemura, Nobuhiro Nagamachi

Patent number: 7898180Abstract: A high pressure discharge lamp having a hermetically sealed portion on opposite sides of an arc tube made of quartz glass and in which a pair of opposed electrodes is located is improved so that electrode rod warping is prevented even when the lamp is repeatedly lit and unlit. Electrode rods extending from the electrodes pass through a center hole in a respective quartz glass body which is positioned and fastened onto each the electrode rods with an infrared reflection membrane composed of a heat-resistant metal being provided on the inner surface of the center hole of the quartz glass body separating the electrode rod from the quartz glass body. The quartz glass body is integrated with the quartz glass forming the hermetically sealed portion and is positioned against a step formed at the boundary between large and small diameter portions of the electrode rod.Type: GrantFiled: December 3, 2008Date of Patent: March 1, 2011Assignee: Ushiodenki Kabushiki KaishaInventors: Toyohiko Kumada, Nobuhiro Nagamachi
