Abstract

Solid state lighting devices include multiple light emitting diodes (LEDs). Each LED includes: an LED device configured to emit light having about a first dominant wavelength; and a phosphor configured to receive at least a portion of the light emitted by the LED device and emit light having about a second dominant wavelength in response. The combined light emitted by the LED device and the phosphor of the first LED of the plurality of LEDs has a first color point, and the combined light emitted by the LED device and the phosphor of the second LED of the plurality of LEDs has a first color point falling around the first LED device and the phosphor. A second color point outside the seven-step McAdam ellipse of a color point.
