A broad bandwidth light source including: a solid state light emitting
device that generates short wavelength light; and quantum dot material
and phosphor material that are each irradiated by some of the short
wavelength light. The short wavelength light has a spectrum with a first
peak wavelength shorter than about 500 nm. The quantum dot material
absorbs some of the short wavelength light and reemits it as long
wavelength light having a spectrum with a second peak wavelength longer
than about 600 nm. The phosphor material absorbs some of the short
wavelength light and reemits it as mid wavelength light having a spectrum
with a peak wavelength between the first and second peak wavelength. The
light source is configured such that some of each light (short, mid, and
long wavelength) is emitted coincidentally as a light having a
chromaticity value near the blackbody locus and a color rendering index
greater than 80.
