The device is further arranged to manipulate the at least one layer to operate in a closed state, in which a surface of the at least one layer is substantially covered with the wavelength converting material and to operate in an open state, in which the surface of the at least one layer is substantially uncovered with the wavelength converting material. The device for adaptable wavelength conversion can be applied in combination with a solar cell or photovoltaic cell thereby enabling the solar cell to receive radiation having a suitable spectrum under varying lighting conditions.Type: ApplicationFiled: November 10, 2009Publication date: September 1, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Rogier A.H. Niessen, Willem F. Pasveer, Johan H. Klootwijk

Patent number: 7997738Abstract: A pressure sensitive adhesive (PSA) is used to attach a plurality of wedge-shaped glass filter segments on a first side to a hub during the color ring build portion of the color wheel fabrication process. A strong adhesive, such as epoxy, is then used to adhere a second side of the filter segments directly to a turning surface of a motor, completing the color wheel fabrication. The epoxy is cured if necessary. The pressure sensitive adhesive can temporarily align the plurality of color filter segments in an alignment. The adhesive between the filter segments and the turning surface can then permanently bond the color filter segments in the alignment.Type: GrantFiled: September 22, 2008Date of Patent: August 16, 2011Assignee: Oerlikon Trading AG, TrubbachInventors: Jean Pierre Menard, Emil Janicek

Patent number: RE43759Abstract: A multiple wavelength light emitting device is provided wherewith the resonance strength and directivity between colors can be easily adjusted for balance. This light emitting device comprises a light emission means 4 for emitting light containing wavelength components to be output, and a semi-reflecting layer group 2 wherein semi-reflecting layers 2R, 2G, and 2B that transmit some light having specific wavelengths emitted from the light emission means and reflect the remainder are stacked up in order in the direction of light advance in association with wavelengths of light to be output. Light emission regions AR, AG, and AB are determined in association with the wavelengths of light to be output.Type: GrantFiled: June 2, 2000Date of Patent: October 23, 2012Assignees: Seiko Epson Corporation, Cambridge Display Technology LtdInventors: Tatsuya Shimoda, Tomoko Koyama, Takeo Kaneko, Jeremy Henley Burroughes
