Abstract
Tunable LED lighting systems, devices and methods are described herein. A light emitting device includes at least a first phosphor-converted LED configured to emit light having a desaturated orange color point characterized by CIE 1976 color coordinates 0.3<u'<0.35 and v′>0.52 and at least a second phosphor-converted LED configured to emit light having a cyan color point characterized by CIE 1976 color coordinates 0.15<u′<0.20 and 0.47<v′<0.52. The first phosphor-converted LED and the second phosphor-converted LED are arranged to combine the light emitted by the first phosphor-converted LED with the light emitted by the second phosphor-converted LED to provide a white light output from the light emitting device.
