Patent number: 7658512Abstract: The invention relates to a lighting unit (1) having a concave reflector (2) with an axis of symmetry (3) and a light emission window (21) bounded by a circumferential edge (20) transverse to the axis, an elongate light source (30) extending substantially along the axis of symmetry (3), which light source (30) is accommodated in a holder (4) opposite the light emission window (21), and a cup-shaped axially positioned cap (5), which cap partly surrounds the light source and forms an optical screening means to intercept unreflected light rays. According to the invention, the cap (5) is surrounded at a distance d by a screening ring (50), which extends over a height h in the direction of the light emission window (21).Type: GrantFiled: April 11, 2003Date of Patent: February 9, 2010Assignee: Koninklijke Philips Electronics, N.V.Inventors: Denis Joseph Carel Van Oers, Jelle Hilbrand Schuurmans

Patent number: 7588361Abstract: An illumination system, preferably for illumination in a car, comprising at least one plain or slightly curved, solid light guide (4) made of transparent material, said light guide receiving light from a light (2) source and being provided with means (5, 6) for extracting light from said light guide, the means for extracting light from said light guide have. Reflecting surfaces (7, 8, 9, 10) the slopes of which are varied as a function of the position of the extracting means in the light guide as well as the position of a reading plane, so as to direct the light flux to a desired reading plane position. Preferably the illumination system a laminated structure of light guide layers, said layers being formed of a light guide layer for diffuse homogeneous illumination (1) and at least one light guide layer (4) for spot illumination of a reading plane.Type: GrantFiled: February 21, 2003Date of Patent: September 15, 2009Assignee: Koninklijke Philips Electronics N.V.Inventors: Christoph Gerard August Hoelen, Cornelis Jojakim Jalink, Nicola Bettina Pfeffer, Jelle Hilbrand Schuurmans, Stefan Marcus Verbrugh

Patent number: 7048409Abstract: A luminaire (1) or a system of a first luminaire (1) and a second luminaire (11) for lighting an object (V). Each luminaire has a housing (2; 12) provided with a plurality of tubular lamps (3, 3?, 3?; 13). The housing (2; 12) has a diffuser (7; 17) positioned in a light emitting window (4; 14) and a side wall (5, 5?; 15), which is orthogonal with respect to the light emitting window (4; 14). In the system, the first and the second luminaire (1; 11) abut one another via the side wall (5, 5?; 15) and/or via the light emitting window (4; 14), wherein an edge (6) of the light emitting window (4) of the first luminaire (1) abuts upon an edge (16) of the light emitting window (14) of the second luminaire (11). The diffusor (7; 17) and the side wall (5, 5?; 15) are made from an optically transparent material. Preferably, the light emitting window (4; 14) is provided with a curtain (21; 31).Type: GrantFiled: January 22, 2002Date of Patent: May 23, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Norbert Dicken, Nicolaas Marinus Fierloos, Jelle Hilbrand Schuurmans

Patent number: 6745506Abstract: A luminaire comprises a relatively thin and flat light-emitting panel (1) having a light-emitting window (2) and, opposite said light-emitting window, a rear wall (3) with opposed edge surfaces (4, 14). At least one of the edge surfaces (4) is light transmitting and associated with a plurality of light sources (5, 5′, 5″, . . . ). Light originating from the light sources (5, 5′, 5″, . . . ) is spread in the panel (1). The invention is characterized in that a plurality of deformities (7, 7′, 7″, . . . ; 8, 8′, . . . ) is provided in the panel (1) for extracting light from the panel (1) via the light emission window (2). The deformities (7, 7′, 7″, . . . ; 8, 8′, . . . ) are clustered so as to form at least one light symbol (27; 28). The configuration of the clusters (17; 18) of deformities (7, 7′, 7″, . . . ; 8, 8′, . . . ) corresponds to the shape of the light symbol (27; 28).Type: GrantFiled: October 25, 2002Date of Patent: June 8, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Theodorus Mattheus Maria Maas, Jelle Hilbrand Schuurmans, Constance J.
