Patent number: 8456087Abstract: 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.Type: GrantFiled: June 26, 2009Date of Patent: June 4, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Thomas G. Steere, Godfried Cornelius Gerardus Maria Manders, Gerardus Marinus Josephus Francis Luijks, Chantal Sweegers, Johan Leopold Victorina Hendrix, Paulus Adrianus Hypolytus Jozef Huijbrechts, Wilhelmus Johannes Jacobus Welters

Patent number: 8337031Abstract: The invention relates to a color-tunable illumination system (10), to a lamp and to a luminaire. The color-tunable illumination system comprises a light source (20) emitting light of a first predefined color (B), and comprises a luminescent material (30) for converting light of the first predefined color into light of a second predefined color (A). The color-tunable illumination system further comprises shielding means (40, 42) arranged for preventing at least part of the light emitted by the light source to impinge on the luminescent material. The light source, the luminescent material and/or the shielding means are changeable from a first situation to a second situation. In the first situation the color-tunable illumination system is arranged for shielding at least part of the luminescent material against impinging light of the first predefined color.Type: GrantFiled: May 5, 2008Date of Patent: December 25, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Rene Theodorus Wegh, Christoph Gerard August Hoelen, Chantal Sweegers, René Jan Hendriks, Martijn Henri Richard Lankhorst, Nicolas Gerardus Antonius Peeters, Martinus Petrus Joseph Peeters, Ramon Pascal Van Gorkom, Matthijs Hendrik Keuper, Coen Theodorus Hubertus Fransiscus Liedenbaum

Patent number: 8172415Abstract: The invention relates to a color-tunable illumination system (10; 12; 14) and a luminaire. The color-tunable illumination system comprises a first light source comprising a first set of light emitting diodes (21, 24), and a second light source comprising a second set of light emitting diodes (31, 37, 34). Both the first and second light source emit light of substantially a first predefined color into a light mixing chamber (60). The light mixing chamber further comprises a first luminescent material (50) converting light of the first predefined color into light of a second predefined color. The first light source is positioned with respect to the first luminescent material for illuminating the first luminescent material with a first flux of light being part of the light emitted by the first light source into the light mixing chamber.Type: GrantFiled: May 20, 2008Date of Patent: May 8, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Rene Theodorus Wegh, Christoph Gerard August Hoelen, Chantal Sweegers, Rene Jan Hendriks, Martijn Henri Richard Lankhorst
