Abstract
A solid state lighting device includes a first group of semiconductor light emitting devices that produces a yellowish white light, a second group of semiconductor light emitting devices that includes at least one light emitting device that produces a reddish orange light, and a third group of semiconductor light emitting devices that includes at least one wavelength down-converted white light device. A combination of the second and third groups produces a sub-mixture of reddish warm white light. A combination of the first, second and third groups produces a mixture of warm white light with a correlated color temperature between 2700k to 3500K and a color rendering index higher than 85.
