摘要:
Light emitting devices having a first LED with a first phosphor, a second LED with a second phosphor and a third LED with a third phosphor to emit a composite white light are described. The first LED and first phosphor emit the red spectral component, the second LED and the second phosphor emit the blue spectral component and the third LED and third phosphor emit the green spectral component of the composite white light. The green spectral component has at least 30% radiant flux in a deep red spectral wavelength region.
