Patent number: 8120279Abstract: A color adjustable lamp may be controlled using a TRIAC dimmer circuit and includes a lamp driving circuit and two or more light sources. Each light source may output light having a different color. By setting an output intensity of each light source, light having a desired color may be output. A circuit or a processing unit of the lamp driving circuit may detect a set phase angle of the TRIAC dimmer circuit by determining a shape of the supplied alternating voltage. According to the determined shape, the circuit or processing unit controls a lamp driver circuit for each light source in order to control the intensity of the light output by each light source and set the color of the color adjustable lamp by adjusting the intensity of the light emitted by each light source.Type: GrantFiled: August 11, 2010Date of Patent: February 21, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Thijs Oosterbaan, Bernardus Lambertus Martinus Van Bakel, Joseph Franciscus Raymond Eijsermans, Nicola Bettina Pfeffer, Marinus Cornelis Raas

Patent number: 7982399Abstract: A high-pressure gas discharge lamp has a bulb of quartz glass and two electrode rods. One end of each electrode rod is connected to a molybdenum foil member embedded in the quartz glass material, while the other end of each electrode rod projects into the gas discharge space inside the bulb. A portion of the electrode rod is embedded in the quartz glass material of the bulb. The surface of said embedded portion of the electrode rod is provided with means dots, recesses and/or protrusions for initiating cracks at predetermined locations in the quartz glass material surrounding the electrode rod during manufacture of the lamp.Type: GrantFiled: March 28, 2007Date of Patent: July 19, 2011Assignee: Koninklijke Philips Electronics, N.V.Inventor: Joseph Franciscus Raymond Eijsermans
