Publication number: 20070138963Abstract: Arc chambers for discharge lamps, such as ceramic metal halide lamps, have ends, where the electrodes for the arc chambers are introduced, that are configured such that, when the arc chambers are arranged vertically, the metal halide additives in the arc chambers will accumulate substantially only on the inner surfaces of the ends, which can have closure walls that are thicker than the thickness of the walls of the body portions of the arc chambers. The ends can be further configured such that the metal halides are deposited substantially uniformly in a thin layer over the ends of the arc chambers. The ends can also be configured in a manner that no sharp edges are provided at the ends of the arc chambers so that corrosive effects to the arc chamber resulting from localized temperature variations are minimized.Type: ApplicationFiled: December 19, 2005Publication date: June 21, 2007Inventors: Timothy Russell, Lei Deng, James Leonard, Thomas Boyle

Publication number: 20070138965Abstract: Low-pressure mercury vapor discharge lamp has an at least partly substantially cylindrical discharge vessel (10) with a length Ldv and with an internal diameter Din. The discharge vessel (10) encloses, in a gastight manner, a discharge space (13) provided with a inert gas mixture and with mercury. The discharge vessel (10) comprises discharge means (electrodes 20a; 20b) for maintaining a discharge in the discharge space (13). According to the invention, the ratio of the weight of mercury mHg in the discharge vessel (10) to the product of the internal diameter Din and the length of the discharge vessel Ldv is given by the relation: Formula (I), wherein C?0.01 ?g/mm2. Preferably, 0.0005?C?0.005 ?g/mm2. Preferably, the discharge vessel (10) contains less than 0.1 mg mercury. The discharge lamp according to the invention operates under unsaturated mercury conditions.Type: ApplicationFiled: September 17, 2003Publication date: June 21, 2007Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Leonie Geerdinck, Esther De Beer, Adrianus Johannes Van Der Pol

Publication number: 20070138969Abstract: In a ballast circuit for operating a discharge lamp, the discharge lamp is ignited by means of resonance. During ignition the lamp voltage is measured and compared with a reference value by a lamp voltage measurement circuit. The operation of the circuit arrangement is adapted in dependency of the outcome of the measurement. Before ignition of the lamp the proper functioning of the lamp voltage measurement circuit is tested. Ignition is only attempted when the lamp voltage measuring circuit is functioning correctly.Type: ApplicationFiled: April 29, 2004Publication date: June 21, 2007Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: John Evarist De Clercq, Hans Feijen
