Oscar A. Chao Pujol has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Color control by alteration of wavelenght converting element
    Patent number: 8486725
    Abstract: A light emitting device is produced by depositing a layer of wavelength converting material over the light emitting device, testing the device to determine the wavelength spectrum produced and correcting the wavelength converting member to produce the desired wavelength spectrum. The wavelength converting member may be corrected by reducing or increasing the amount of wavelength converting material. In one embodiment, the amount of wavelength converting material in the wavelength converting member is reduced, e.g., through laser ablation or etching, to produce the desired wavelength spectrum.
    Type: Grant
    Filed: June 4, 2012
    Date of Patent: July 16, 2013
    Assignee: Philips Lumileds Lighting Company, LLC
    Inventors: Steven Paolini, Michael D. Camras, Oscar A. Chao Pujol, Frank M. Steranka, John E. Epler
