Patent number: 8029142Abstract: 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: November 12, 2010Date of Patent: October 4, 2011Assignee: 3M Innovative Properties CompanyInventors: Arlie R. Conner, Sean M.

Patent number: 7540616Abstract: Light emitting diodes (LEDs) emit light at a first wavelength. A phosphor material close to LEDs converts at least some of the light to a second wavelength. The light at both wavelengths passes through a light collecting unit. A reflecting polarizer transmits both wavelengths in a first polarization state and reflects light at both wavelengths in a second, orthogonal, polarization state. Light reflected by the reflective polarizer is directed back towards the phosphor material without any substantial increase in angular range. The resulting output light beam contains polarized light at the first and second wavelengths. In some embodiments, an array of LEDs includes LEDs that emit light at a first wavelength and others that emit light at a second wavelength. The phosphor material is disposed on the LEDs emitting the light at the first wavelength.Type: GrantFiled: December 23, 2005Date of Patent: June 2, 2009Assignee: 3M Innovative Properties CompanyInventor: Arlie R.
