Patent number: 8267528Abstract: An illumination source includes a number of light emitting diodes (LEDs) operating at a first wavelength. Light from the LEDs illuminates a phosphor material that generates light at a second wavelength. A reflective polarizer transmits light at the second wavelength in a first polarization state and reflects light at the second wavelength in a second polarization state orthogonal to the first polarization state. The light at the second wavelength reflected by the reflective polarizer is directed back towards the phosphor material without an increase in angular range. In some embodiments the LEDs, having a conformal layer of phosphor material, are attached directly to the first surface of a liquid cooled plate. A liquid coolant contacts a second surface of the plate.Type: GrantFiled: September 1, 2011Date of Patent: September 18, 2012Assignee: 3M Innovative Properties CompanyInventors: Arlie R. Conner, Sean M. Donnelly, Peter R. Oehler

Patent number: 7029130Abstract: The present invention is particularly useful for projection systems in which portions of an unwanted light beam overlap with the image beam. Such an overlap reduces the image contrast. Under the present invention, an aperture is used to restrict the extent of the unwanted beam while an integrator changes the shape of the light beam illuminating the image display device. The integrator changes the illumination beam so as concentrate the light in those areas of the illumination beam that are transmitted through the aperture. When the aperture and the integrator are used together in the projection system, both the image brightness and the image contrast are increased.Type: GrantFiled: December 30, 2003Date of Patent: April 18, 2006Assignee: 3M Innovative Properties CompanyInventors: Bruce L. Cannon, Gary B. Kingsley, Frederic R. Engstrom, Peter R. Oehler

Patent number: 6481855Abstract: A multimedia projector (30) includes an image processor (36) that forms an image on an image forming device (38). Illumination reflecting off the image, propagates through a projection lens (50), along a projection axis (18), and lands on a projection surface (20) as a projected image (16). An elevator mechanism (52) tilts the projection axis to position the projected image on the projection surface, which tilting causes keystoning of the projected image. In a first embodiment, an inclinometer (56) generates angle data indicative of a projection axis angle (58). A controller (34) receives the angle data and coacts with the image processor to predistort the image to compensate for the keystoning. In a second embodiment, the elevator mechanism includes an elevator shaft (60) having teeth (66) that alternately pass and obscure light as the elevator shaft undergoes movement. An optical sensor (70) generates angle data proportional to a distance moved by the elevator shaft.Type: GrantFiled: January 12, 2001Date of Patent: November 19, 2002Assignee: InFocus CorporationInventor: Peter R.
