Patent number: 9748522Abstract: The invention relates to an illumination system comprising a light emitting device and a beam shaping element for generating an angular distribution of the light emitted from the illumination system. The beam shaping element is configured for recycling at least a part of the light emitted from a light emitting surface of the light emitting device via reflection back towards the light emitting surface. The illumination system further comprises a diffuser arranged substantially parallel to the light emitting surface for diffusing at least part of the recycled light. The diffuser is constituted of a translucent diffuser and/or a diffusely reflective electrode layer of the light emitting device. Limiting the angular distribution by recycling light, using the beam shaping element for recycling light via reflection, reduces glare when the illumination system is used in general lighting applications.Type: GrantFiled: April 21, 2010Date of Patent: August 29, 2017Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: Coen Adrianus Verschuren, Ferry Zijp

Publication number: 20090190461Abstract: Multi layer near-field optical recording using a moderate numerical aperture (NA) is superior to the high-NA (NA=2.0) first-surface single-layer technique. The use of very flat and thin spacer layers limits spherical aberration due to difference in layer depth. The thin spacer layers may have a high refractive index because their thickness allow for a relatively high absorption constant. This makes possible in principle an m-layer system, e.g. m=4, with NA=1.6 which may include a flat, protective cover layer. Further a medium for use in such a system is described.Type: ApplicationFiled: April 15, 2005Publication date: July 30, 2009Applicant: Koninklijke Phillips Electronics N.V.Inventors: Martinus Bernardus Van Der Mark, Ferry Zijp, Sjoerd Stallinga
