Publication number: 20090027891Abstract: The present invention relates to a device (200) for electrically controlling shaping of a light beam. The device comprises primary optics (202) that is arranged to shape the light beam originating from a light source (201). The device further comprises an electrically controllable optical element (203) arranged to change the direction of the light falling onto it, when the element is in a light-redirecting mode. The optical element can be an electrically controllable scattering element e.g. created by using a PDLC material or an LC gel. The degree of light redirection of the optical element is controlled by applying an electric field to the LC material. Finally, the device comprises secondary optics (204) arranged to shape the scattered, diffracted or refracted light beam from the optical element.Type: ApplicationFiled: October 10, 2005Publication date: January 29, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Rifat Ata Mustafa Hikmet, Johannes Petrus Maria Ansems, Christoph Gerard August Hoelen, Ties Van Bommel, Lingli Wang

Publication number: 20080192457Abstract: A brightness enhancing means (5), comprising a collimating means (6) having a receiving area (61), an output area (62) being larger than said receiving area (61), and sidewalls (63) at least partially extending between said receiving and output areas, is provided. At least a portion of the sidewalls (63) of said collimating means (6) comprises a first filter being arranged to reflect light of a first light property, which light is received via said receiving area (61) of said first collimating means (6), towards said output area (62) of said first collimating means (6), wherein said first filter is a dichroic filter or a polarization filter.Type: ApplicationFiled: May 18, 2006Publication date: August 14, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Marcellinus Petrus Carolus Michael Krijn, Ramon Pascal Van Gorkom, Michel Cornelis Josephus Marie Vissenberg, Johannus Gerardus Van Beek, Lingli Wang

Publication number: 20080186709Abstract: A variable reflector device, comprising a reflector (6) arranged to direct light from a light source (7) and a casing (5) containing the reflector (6), a portion of said casing (5) being transparent to light directed by the reflector (6). The reflector (6) is formed by a meniscus (2) at an interface between two immiscible fluids (3,4) contained in said casing (5). According to this design, the spatial distribution of light from the light source is changeable by changing the shape of the meniscus between the two fluids. Since a change in shape of the meniscus is effected by a displacement of fluids rather than of mechanical parts, the change in reflector shape can generally be performed faster and with less energy consumption than is the case with previously known designs. Further, a meniscus between two immiscible fluids can, due to the nature of fluids, take on several different shapes, which is not the case when a solid body reflector is utilised.Type: ApplicationFiled: January 9, 2006Publication date: August 7, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Stein Kuiper, Bernardus Hendrikus Wilhelmus Hendriks, Lingli Wang, Christoph Gerard August Hoelen, Johannes Petrus Maria Ansems

Publication number: 20080005716Abstract: A user logic design for a mask-programmable logic device (“MPLD”) may be designed on a comparable or compatible user-programmable logic device (“UPLD”) and migrated to the MPLD, or may be designed directly on an MPLD. If the design is designed on a UPLD, the constraints of the target MPLD—i.e., differences between the devices—are taken into account so that the migration will be successful. If the design is designed directly on an MPLD, constraints of a comparable compatible UPLD are taken into account if the user indicates that the design will be migrated to the UPLD for testing. This means that when a logic design is intended to be migrated back-and-forth between a UPLD and an MPLD, only the intersection of features can be used. To facilitate migration, fixed mappings between pairs of devices may be created.Type: ApplicationFiled: September 19, 2007Publication date: January 3, 2008Applicant: ALTERA CORPORATIONInventors: Steven Perry, Gregor Nixon, Larry Kong, Alasdair Scott, Andrew Hall, Lingli Wang, Chris Dettmar, Jonathan Park, Richard Price

Patent number: 6367935Abstract: A method for the elimination of image speckles in a scanning laser projection is suggested, in which a phase hologram is used for dividing the illumination beam of the projector into partial beams. The partial beams are heterodyned again on the image screen within the image element (pixels) to be projected in such a way that differing speckle patterns are formed which average each other out in the eye of the viewer over time and/or space. Thus, a device is provided especially for the laser projection which substantially eliminates or reduces the speckles at the viewer. However, the beam form and the beam density are hardly or not changed.Type: GrantFiled: October 12, 1999Date of Patent: April 9, 2002Assignee: EADS Deutschland GmbHInventors: Lingli Wang, Theo Tschudi, Thorsteinn Halldorsson, Palmi Petursson
