Abstract

A solid state lighting apparatus includes a plurality of light emitting diodes (LEDs). Each of the LEDs includes an LED device configured to emit light having about a first dominant wavelength and a phosphor configured to receive at least some of the light emitted by the LED device and responsively emit light having about a second dominant wavelength. A combined light emitted by the LED device and the phosphor of a first one of the plurality of LEDs has a first color point and a combined light emitted by the LED device and the phosphor of a second one of the plurality of LEDs has a second color point that falls outside a seven step Macadam ellipse around the first color point.
