Patent number: 8465183Abstract: A lighting device (1) comprising an LED-unit (5), a collimator (2) and a housing (3), the LED-unit (5) is rigidly coupled to the collimator (2) only, so that no substantial forces can be applied to the LED-unit (5). A non-rigid heat transferring medium (10) is provided in a cavity (12) in the housing (3), to dissipate heat, generated by the LED-unit (5). The LED-unit (5) is therefore at least partly contained in the heat transferring medium (10).Type: GrantFiled: December 4, 2006Date of Patent: June 18, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Gunnar Luettgens, Benno Spinger, Egbert Lenderink, Daniël Anton Benoy

Publication number: 20090073710Abstract: An illumination system has a plurality of light-emitting diodes (R, G, B), at least one light-collimating section (12,12?) arranged along a longitudinal axis (25) of the illumination system. The light-collimating sections merges into a light-mixing section (3) having a plurality of side-faces along the longitudinal axis (25). Light propagation in the light-mixing section is based on total internal reflection. The light-mixing section is provided with a light-exit window (13) emitting light towards an imaginary projection surface normal to the longitudinal axis.Type: ApplicationFiled: November 14, 2005Publication date: March 19, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Joseph Ludovicus Antonius Maria Sormani, Gunnar Luettgens
