  • COLOR CONTROL BY ALTERATION OF WAVELENGHT CONVERTING ELEMENT
    Publication number: 20120238041
    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: Application
    Filed: June 4, 2012
    Publication date: September 20, 2012
    Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.

  • Display device with solid state fluorescent material
    Patent number: 7939996
    Abstract: A display device (100) comprising a plurality of lighting units (101), each lighting unit comprising at least one light emitting diode (202) being provided with a fluorescent element (203) arranged to absorb at least part of the light emitted by said light emitting diode and emit light of a wavelength range different from that of the absorbed light is provided. The fluorescent element (203) comprises at least one phosphor being an europium(II)-activated halogeno-oxonitridosilicate of the general formula EaxSiyN2/3x+4/3y:EuzOaXb.
    Type: Grant
