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.
