Publication number: 20110222288Abstract: There is disclosed a lighting device of which the light sources and/or optical elements are hidden in a first cover state associated with a first light state. This enables an unobtrusive lighting system in the first cover state. In a second cover state associated with a second light state, optical elements, e.g. shutters or beam shaping elements, are switched, induced by the heat or the light flux generated by the light sources, such that the lighting system can function properly.Type: ApplicationFiled: November 12, 2009Publication date: September 15, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Michel C.

Patent number: 7956820Abstract: The present invention relates to a display device comprising an outer display stacked with an inner display and being arranged to be operable in a first, multiple view mode and a second, single view mode. An idea of the invention is to arrange an electrophoretic display on top of an emissive display. The display device may be operated in two modes; a first mode being a multiple or dual view mode and a second mode being a single view mode. In order to activate the single view mode, the outer display is set in a transparent state and the inner display is turned on, such that it displays desired objects. In the multiple view mode, the outer display is functioning as a 3D-barrier. Hence, some of the picture elements of the outer display are set in a transparent state while others are set in an opaque state. The viewer sees a different picture with each respective eye, and will accordingly experience a multiple view picture of an object that is displayed on the inner display.Type: GrantFiled: June 13, 2006Date of Patent: June 7, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Edzer Huitema, Geardus P. Karman, Rogier Cortie, Jaap Bruinink, Olaf Gielkens, Antonius G. H. Verhulst, Murray F. Gillies, Michel C. J. M. Vissenberg

Publication number: 20110085351Abstract: The invention relates to an illumination system (10), a backlighting system and a display device. The illumination system comprises a light source (20) configured to emit light via a light guide (30) to a light exit window (40) of the illumination system. The light guide has a front wall (32) arranged opposite a rear wall (34) so as to guide light in a direction substantially parallel to the front wall. A distance (D) between the light guide (30) and the light exit window (40) reduces towards an edge (42) of the light exit window (40). The light guide (30) further comprises a light entrance window (36) for receiving the light from the light source which is arranged away from the edge of the light exit window. The illumination system according to the invention has, inter alia, the effect that its thickness may be reduced at the edge of the light exit window.Type: ApplicationFiled: April 1, 2009Publication date: April 14, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Fetze Pijlman, Michel C.J.M. Vissenberg, Marcellinus P.C.M. Krijn, Lars C. Casper

Publication number: 20100237359Abstract: A light-emitting device (100), comprising a plurality of light emitting diodes (107) arranged spaced apart from each other on a substrate (108), is provided. The device further comprises a light guide plate (101) having a front surface (102) and an opposing back surface (103) that is provided with an array of protrusions (104) extending towards said substrate. The light guide plate is arranged such that light-emitting diodes emits light towards light receiving faces (105) of the protrusions (104). Further, collimators (110) are arranged between the light emitting diodes and the light receiving faces, to collimate the light before it enters the light guide plate. The light from the plurality of LEDs will be transmitted in to the light guide plate and will be distributed therein before exiting the light guide plate via the front side thereof. Thus, the present invention provides a light-emitting device that provides well-distributed and collimated light from a plurality of point light sources.Type: ApplicationFiled: September 12, 2007Publication date: September 23, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N VInventors: Hugo J. Cornelissen, Willem L. Ijzerman, Michel C. J. M. Vissenberg

Publication number: 20100073925Abstract: A light emitting device is provided, comprising a light guide plate (100) and at least one light emitting diode (110). An array of mutually spaced apart reflective surface elements (103, 103?) is arranged between said back surface (102) and said front surface (103). The reflective surface elements (103, 103?) are non-parallel relative to said back surface (101) and front surface (102), and have a front side (104) facing said front surface (102) and a back side (105) facing said back surface (101). The back surface (105) of a reflective surface element (103) faces the front surface (104) of an adjacent reflective surface element (103?). The at least one light emitting diode (110) is arranged to emit light into a region (111) between two adjacent ones of said reflective surface elements (103, 103?). Since the reflective surface elements are located within the light guide, both the back surface and the front surface of the light guide plate may be made flat.Type: ApplicationFiled: October 12, 2007Publication date: March 25, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Michel C.J.M.

Publication number: 20100061094Abstract: A light guide arrangement comprising a light guide (101) provided with through holes (103), multiple light source sites (117) and out coupling structures (119) for directing light out from the light guide. There is at least one wire (105a) and each wire is provided along a sequence (103a-103d) of through holes in the light guide. At each through hole in the sequence, a first wire portion (108a) extends from a first side of the light guide and is in engagement with a second wire portion (110a) extending from a second side. Wires that are stitched like this allow for a low degree of optical contact with the light guide and thus allow wires and components to be attached without light leaking out undesirably. The wires are preferably electrically conducting wires. A luminarie comprises the light guide arrangement and light sources, and in a method for providing the wires to a light guide arrangement, the wires are sewed to the light guide.Type: ApplicationFiled: September 24, 2007Publication date: March 11, 2010Applicant: Koninklijke Philips Electronics N.V.Inventors: Willem L.

Patent number: 6275568Abstract: The invention relates to an X-ray apparatus which includes an adjustable X-ray filter. In order to adjust an intensity profile of the X-ray beam, an X-ray absorbing liquid is transported to filter elements of the X-ray filter. Such transport is susceptible to gravitational forces which lead to an irregular hydrostatic pressure distribution in the X-ray filter. In order to reduce the effects of the gravitational forces on the transport of the X-ray absorbing liquid, the duct connecting the filter elements to the reservoir is subdivided into sub-ducts and the reservoir is subdivided into chambers, each chamber being connected to at least one sub-duct. The X-ray apparatus also includes means for keeping the sub-ducts aligned with a horizontal plane.Type: GrantFiled: December 22, 1999Date of Patent: August 14, 2001Assignee: U.S. Philips CorporationInventors: Menno W.
