US Patent:

20100181529, Jul 22, 2010

Filed:

Jan 12, 2010

Appl. No.:

12/686142

Inventors:

Biying Huang - Henderson NV, US
Xiongfei Shen - Newark CA, US
Yi-Qun Li - Danville CA, US

Assignee:

INTEMATIX CORPORATION - Fremont CA

International Classification:

H01M 4/88

US Classification:

2521821

Abstract:

The present invention provides a cost effective process of generating LiMZO/carbon composite material. Further, this novel method of preparation can be modified by adding a dopant and the calcinations can be carried out using microwave heating to reduce the synthesis time and cost. The LiMZO/carbon composite material can be used as a cathode for a secondary electrochemical cell. Selection of one or more metals in the cathode material can be used change the voltage, the capacity, and the energy density of the electrochemical cell.

H05B 33/12

US Classification:

313503, 428690, 428446, 428691, 427162

Abstract:

The teachings are generally directed to phosphors having combination coatings with multifunctional characteristics that increase the performance and/or reliability of the phosphor. The teachings include highly reliable phosphors having coatings that contain more than one inorganic component, more than one layer, more than one thicknesses, more than one combination of layers or thicknesses, a gradient-interface between components, a primer thickness or layer to inhibit or prevent leaching of phosphor components into the coatings, a sealant layer to inhibit or prevent entry of moisture or oxygen from the environment, a mixed composition layer as a sealant and multifunctional combination coatings.

H01L 33/50
H01L 25/13

Abstract:

A white light emitting device or LED-filament comprises: a solid-state light emitter (LED) operable to generate excitation light; a first phosphor associated with the solid-state light emitter to generate light with a peak emission wavelength in a range 500 nm to 575 nm; and a second phosphor associated with the solid-state light emitter to generate light with a peak emission wavelength in a range 600 nm to 650 nm, wherein a percentage decrease in conversion efficiency corresponding to an increase in excitation light photon density exhibited by the second phosphor is larger than a percentage decrease in conversion efficiency corresponding to the same increase in excitation light photon density exhibited by the first phosphor.
