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.
