  • Patent number: 9310030
    Abstract: A lighting device comprising a light source and a diffuser spaced from the light source. The lighting device further comprises a wavelength conversion material disposed between the light source and the diffuser and spaced from the light source and the diffuser, wherein the diffuser is shaped such that there are different distances between the diffuser and said conversion material at different emission angles. In other embodiments the diffuser includes areas with different diffusing characteristics. Some lamps are arranged to meet A19 and Energy Star lighting standards.

  • Publication number: 20130003346
    Abstract: Solid state modules and fixtures comprising different combinations and arrangements of a light source, one or more wavelength conversion materials, thermally conductive connection adapters allowing dissipation of heat outside of the module, and a remote power supply unit. This arrangement allows for greater thermal efficiency and reliability while employing solid state lighting and providing emission patterns that are equivalent with ENERGY STARĀ® standards. Some embodiments additionally place compensation circuits, previously included with power supply units, on the optical element itself, remote from the power supply unit. Various embodiments of the invention may be used to address many of the difficulties associated with utilizing efficient solid state light sources such as LEDs in the fabrication of lamps or bulbs suitable for direct replacement of traditional incandescent bulbs or fixtures using bulbs.

  • Publication number: 20050153136
    Abstract: The present disclosure relates to coating formulations for neodymium-iron-boron type magnetic powders manufactured from rapid solidification processes for the purpose, inter alia, of corrosion and oxidation resistance when exposed to aggressive environments. The coating formulation preferably contains an epoxy binder, curing agent, an accelerating agent, and a lubricant. By incorporating coupling agents and optionally, other specialty additives with the magnetic powder and the organic epoxy components, additional oxidation and corrosion prevention, enhanced adhesion and dispersion between the filler and matrix phases can be achieved. This disclosure relates to all such rare earth-transition metal-boron (RE-TM-B) powders produced by rapid solidification and encompasses both the bonded magnet products that include combinations of the materials mentioned and the application processes.
