  • Patent number: 8922108
    Abstract: Remote component devices, systems, and methods are disclosed. In one aspect, remote component devices, systems, and methods can include a body for lockably securing the remote component to a housing. Devices, systems, and methods can also include one or more light emitting devices disposed over the body. An optical material can be remotely located at least a first distance away from the one or more light emitting devices. Remote component devices, systems, and methods disclosed herein can be used as replacements and/or equivalent light products for standard filament light bulbs and compact fluorescent lamp (CFL) bulbs.

  • Publication number: 20140217433
    Abstract: Light emitter devices for light emitting diodes (LED chips) and related methods are disclosed. In one embodiment a light emitter device includes a substrate and a chip on board (COB) array of LED chips disposed over the substrate. A layer having wavelength conversion material provided therein is disposed over the array of LED chips for forming a light emitting surface from which light is emitted upon activation of the LED chips. In some aspects, the wavelength conversion material includes phosphoric or lumiphoric material that is settled and/or more densely concentrated within one or more predetermined portions of the layer. In some aspects, the devices and methods provided herein can comprise a lumen density of approximately 30 lm/mm2 or greater.
