  • Patent number: 8829777
    Abstract: There is herein described an LED light source comprising an LED and a ceramic wavelength converter positioned to receive at least a portion of the light emitted by said LED, said ceramic wavelength converter converting at least a portion of the light emitted by said LED into light of a different wavelength, said ceramic wavelength converter comprising a chlorosilicate phosphor and having a density at least about 90% of theoretical density. The chlorosilicate phosphor is preferably a green-emitting Ca8Mg(SiO4)4Cl2:Eu2+ phosphor.
    Type: Grant
    Filed: September 27, 2010
    Date of Patent: September 9, 2014

  • Patent number: 7897234
    Abstract: A potting compound for electronic components comprises a first composition of asphalt and sand and a second composition that attenuates the forces normally applied by the first composition when it is used alone. The force attenuator preferably comprises solvent-refined heavy paraffinic petroleum oil from about 0.1 to 20 wt % of the compound.
