| 20090085049 | Phosphor down converting element for an LED package and fabrication method - There is provided a phosphor down converting element based on fluoropolymer resin and a method for fabricating the same. There is further provided a method for using said phosphor down converting element to generate white light from a radiation source. The method for fabricating phosphor down converting element includes preparing an appropriate phosphor powder mixture that is capable of absorbing a first band of wavelengths and emitting a second band of wavelengths being greater in length than the first bands, incorporating the phosphor powder mixture into or on a phosphor carrier element comprising a fluoropolymer material, and molding the phosphor down converting elements into useful shapes. Fluoropolymers are the most chemically inert of all plastics, can withstand both extremely high and low temperatures, and show a resistance to weavering and UV degradation, making fluoropolymers optimal for use as a phosphor carrier. | 04-02-2009 |
| 20090162667 | Lighting device having backlighting, illumination and display applications - The present invention provides a lighting device such as a backlighting device, and display thereof such as LCD display. The lighting device comprises one or more radiation sources such as UV-blue LED and a layer of air- and moisture-sensitive phosphor, such as complex fluoride activated with Mn | 06-25-2009 |
| 20090167151 | Lighting device having illumination, backlighting and display applications - Provided are a lighting device, a backlighting device, and a display device that comprise a radiation source such as LED and wavelength converting members comprising phosphors. In one embodiment, self-absorption within the devices is suppressed or reduced by placing a selective reflector between two wavelength converting members, and the wavelength converting member emitting light with longer peak wavelength is substantially isolated from the irradiation of another wavelength converting member emitting light with shorter peak wavelength. In other embodiments, the wavelength converting members are arranged in strip configuration; or in adjacent hexagons configuration. | 07-02-2009 |
