    Abstract: Light emitting diode (LED) devices, components and systems are provided. LED devices include a submount with a plurality of LEDs disposed thereon. The LEDs mounted on a submount can be spaced apart at predetermined dimensions to control the gaps between each of the plurality of LEDs. By controlling the gaps between LEDs the optical output from the LED device can be optimized, including improving emission and/or color uniformity, minimizing or eliminating deadspots in the light emission, and/or minimizing or eliminating an optical cross. A phosphor layer can be disposed on the plurality of LEDs and between the LEDs in the gaps therebetween.

    Abstract: Light emitting devices include a red solid state emitter and a blue-shifted-yellow solid state emitter that comprises a blue light emitting diode (“LED”) and an associated luminophoric medium that includes first, second and third luminescent materials that emit light having a dominant wavelength in the respective green, yellow and red color ranges. Each blue-shifted-yellow solid state emitter emits light having a color point on the 1931 CIE Chromaticity Diagram in a region defined by ccx, ccy coordinates of (0.226, 0.295), (0.295, 0.298), (0.323, 0.360), (0.344, 0.358), (0.422, 0.496), (0.391, 0.517), (0.371, 0.477), (0.506, 0.303), (0.226, 0.295). These devices emit light having a color point that is within a 4-step MacAdam ellipse of the black-body locus.
