20090322224 | STARTING AID FOR HID LAMP - An arc discharge light source ( | 12-31-2009 |
20100181910 | HIGH-PRESSURE DISCHARGE LAMP COMPRISING A STARTER ANTENNA - A high-pressure discharge lamp comprising an inner bulb ( | 07-22-2010 |
20110115371 | HIGH-PRESSURE SODIUM VAPOR DISCHARGE LAMP WITH HYBRID ANTENNA - A discharge lamp includes a body portion having inner and outer body walls and first and second ends. The inner body wall defines at least part of a cavity located between the first and second ends. First and second end parts have inner end-part and outer end-part walls and a hole extending between the inner end-part wall and the outer end-part wall. The first and second end parts are each located, at least in part, within the cavity and separate from each other so as to maintain a gas under pressure. First and second electrodes are included in the cavity. An antenna has first and second antenna ends and is formed on the outer body wall of the body portion and the outer end-part wall of at least one of the first and second end parts. The antenna is not directly connected to the first and second electrodes. | 05-19-2011 |
20120146496 | HIGH-PRESSURE DISCHARGE LAMP WITH STARTING AID AND METHOD FOR PRODUCING THE SAME - In a high-pressure discharge lamp including a ceramic discharge vessel, a secure connection between a hybrid antenna as starting aid and a leadthrough of the discharge vessel is provided by virtue of the fact that a means between leadthrough and extension limits the ohmic resistance between leadthrough and hybrid antenna preferably to at most | 06-14-2012 |
20120181924 | UV ENHANCER FOR DISCHARGE LAMP AND MANUFACTURING METHOD THEREOF - Starting performance is improved by efficient UV-light irradiation, suppressing creeping discharge or atmospheric discharge at the outside of a glow discharge tube, and preventing cracks in a pinch seal portion even when an external force is exerted in the direction of bending a lead. In a discharge tube for emitting a UV-light, a light emitting chamber is formed on one side of a pinch seal portion for sealing an electrode assembly, and a lead protrusion port is formed on the opposite side thereof while pinching the seal portion, the lead protrusion port is formed as a sleeve having a predetermined gap relative to the lead, an external electrode disposed to the outside of the light emitting chamber includes a hold formed by bending fabrication of a metal plate. | 07-19-2012 |
20130113371 | HIGH-PRESSURE DISCHARGE LAMP WITH IGNITION AID - A high-pressure discharge lamp having an ignition aid is provided. The discharge lamp may include: a discharge vessel consisting of ceramic or quartz glass which is sealed at two ends and which is accommodated in an outer bulb which is likewise sealed at two ends, the discharge vessel having two ends in which electrodes are fastened, two power supply lines holding the discharge vessel in the outer bulb, a UV enhancer with a single electrode as ignition aid being accommodated in the outer bulb, wherein the UV enhancer is positioned in the vicinity of a second end of the discharge vessel, while a feed line is routed from the first power supply line along the discharge vessel and is connected to the UV enhancer, the feed line being capacitively coupled to the first power supply line, the UV enhancer being installed between the feed line and the second power supply line. | 05-09-2013 |
20140217884 | FLASH TUBE WITH AN EXTERNAL TRIGGERING WIRE - The present invention relates to the field of flash tubes for photographic use, in particular to a flash tube comprising a trigger element for triggering a flash in the flash tube. Accordingly, a flash tube is provided. The flash tube comprises a glass envelope enclosing a gas for use in a flash tube; a first electrode inside the glass envelope; a second electrode inside the glass envelope; and an electrically conductive trigger element being configured to receive a high voltage pulse for at least partly ionizing the gas inside the glass envelope in order to trigg a flash in said flash tube, wherein said electrically conductive trigger element extends along the glass envelope from a first point on the glass envelope adjacent to the first electrode to a second point on the glass envelope adjacent to the second electrode such that a single unified spark stream which bridges the first and second electrodes inside the glass envelope is formed in the at least partly ionized gas adjacent to said electrically conductive trigger element when said electrically conductive trigger element receives the high voltage pulse. | 08-07-2014 |
20140354147 | GAS DISCHARGE TUBE INCLUDING A STARTING AID - In various embodiments, a gas discharge tube having a starting aid may include a discharge vessel with at least one open end, in which end a stopper with a continuous stopper bore is inserted; and an electrical leadthrough, which is inserted into the respective stopper bore and is fuse-sealed into the stopper bore. The starting aid extends as far as into the stopper bore. | 12-04-2014 |
