Patent number: 7414366Abstract: A ceramic discharge vessel for a high-intensity discharge lamp includes a hollow body and two capillaries attached to the body. The capillaries have respective electrodes therein, where portions of the electrodes inside the body are spaced from each other and have longitudinal axes that are not coplanar. That is, in contrast to the prior art where the longitudinal axes are coplanar, the capillaries herein are moved (in effect, rotated) to positions in which a first plane defined by a longitudinal axis of one capillary and a first point where a second capillary is attached to the body is intersected by a longitudinal axis of the second capillary only at the first point.Type: GrantFiled: June 20, 2005Date of Patent: August 19, 2008Assignee: Osram Sylvania Inc.Inventors: Victor E. Perez, Jeffrey T. Neil, Gregory Zaslavsky

Patent number: 6774547Abstract: A fluted feed-through for a discharge lamp includes a fluted ceramic core with plural channels and plural individual molybdenum or tungsten wires running in different ones of the plural channels. The wires are twisted together at the ends of the feed-through. The feed-through is insertable into a capillary tube of a ceramic discharge lamp. The wires of the feed-through have a different thermal coefficient of expansion than the ceramic discharge lamp. The wires are thin enough so that the absolute magnitude of the thermal coefficients of expansion is sufficiently small to prevent seal cracks and leaking.Type: GrantFiled: June 26, 2003Date of Patent: August 10, 2004Assignee: Osram Sylvania Inc.Inventors: Gregory Zaslavsky, James Avallon, Joanne Browne
