Publication number: 20180061626Abstract: The present invention relates to a high-intensity discharge lamp (1) comprising a discharge vessel (2) enclosing a filling in a discharge chamber (3), and a pair of electrode rods (4, 5) being formed of a material which is free of thorium and protruding from opposite sides into the discharge chamber (3). The diameter ED of the electrode rods (4, 5) in the discharge chamber (3) N satisfies the formula (I), wherein W represents the value of the nominal lamp power in mW and Ed represents the value of the distance of the electrode rods (4, 5) in the discharge chamber (3) in mm, and wherein the nominal lamp power W is between 20 W and 50 W. With the above formula, high-intensity discharge lamps can be easily designed with different nominal powers and/or 10 electrode distances without time consuming experiments in order to achieve an optimum performance.Type: ApplicationFiled: March 11, 2016Publication date: March 1, 2018Inventor: Klaus Schoeller

Patent number: 9666425Abstract: A gas discharge lamp has an inner bulb with a discharge vessel with two sealing sections thereon, from which electrodes protrude into the discharge vessel, each electrically connected with a conductor in the associated sealing section to supply current to the electrodes. The lamp also has an outer bulb surrounding the discharge vessel, leaving a cavity therebetween. Close to at least one of the electrodes in or near a transitional area between the discharge vessel and the associated sealing section on an outside of the inner bulb is arranged potential-free a conductive structure which on application of a voltage to the electrodes influences the electrical field adjacent the electrodes such that a discharge arc travels from the electrode first in the direction of a wall section of the discharge vessel adjacent the electrode and then over the inside of the wall toward the other electrode.Type: GrantFiled: December 22, 2005Date of Patent: May 30, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Norbert Lesch, Manfred Westemeyer, Klaus Schoeller

Patent number: 8674591Abstract: A gas-discharge lamp (1) is described having two electrodes (4, 5) that project into the discharge vessel (3) of the lamp. The lamp further comprises an outer envelope (18) that surrounds the discharge vessel (3), with an airtight seal, while leaving an outer cavity (20) between itself and the discharge vessel (3) and that is filled with a gas at a pressure of not more than 1,000 mbar. In the outer cavity (20), there is a single conductor, electrically connected to one of the electrodes, that is in direct contact with the gas filling in the cavity (20) to allow a high-voltage pulse to be applied for igniting a discharge between the conductor and its surroundings. Also described are a method of operating a gas-discharge lamp of this kind and various methods of producing gas-discharge lamps of this kind.Type: GrantFiled: June 28, 2007Date of Patent: March 18, 2014Assignee: Koninklijke Philips N.V.Inventors: Marcus Jozef Henricus Kessels, Klaus Schoeller

Patent number: 8602616Abstract: It is provided a lamp, particularly halogen lamp, for a headlight of a motor vehicle, comprising a light source (12) for emitting mainly white light, a mainly transparent envelope (14) encapsulating the light source (12) and a filter element (22) provided at the envelope (14), wherein the filter element (22) is adapted for deflecting visible light of a predefined wavelength interval such, that mainly blue light can be provided above a bright/dark-cutoff (28). Since the deflected bluish light is above the bright/dark-cutoff (28) an oncoming driver recognizes earlier the light. At the same time the oncoming driver is not blinded by the blue light above the bright/dark-cutoff (28), since not the whole emitted light (40) but only a smaller wavelength interval is directed above the bright/dark-cutoff (28).Type: GrantFiled: November 9, 2009Date of Patent: December 10, 2013Assignee: Koninklijke Philips N.V.Inventors: Bernd Schoenfelder, Manfred Westemeyer, Klaus Schoeller, Kirsten G.
