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.

Abstract: A semiconductor light emitting device includes an LED and a recipient luminophoric medium that includes a first narrow-spectrum luminescent material that down-converts a first portion of the radiation emitted by the LED to radiation having a first peak wavelength in the green-yellow color range and a second narrow-spectrum luminescent material that down-converts a second portion of the radiation emitted by the LED to radiation having a second peak wavelength in an orange-red color range. The first and second luminescent materials and any additional narrow-spectrum luminescent materials that are included in the recipient luminophoric medium generate at least 80% of the light emitted by the recipient luminophoric medium. A CRI value of the combined light emitted by the semiconductor light emitting device is at least 60 and less than 80.
