    摘要： A light emitting apparatus having a light source for emitting short wavelength radiation and an optic device configured to receive the radiation emitted from the light source. A device directs at least some of the short wavelength radiation emitted from the light source into the optic device and a down conversion material receives at least some of the short wavelength radiation directed into the optic device in one spectral region and emits the radiation in another spectral region.

    摘要： A broad bandwidth light source including: a solid state light emitting device (102) that generates short wavelength light; and quantum dot material (104) and phosphor material (106) 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 500nm. The quantum dot material (104) 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 600nm. The phosphor material (106) 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 wavelengths. The light source is configured such that some of each light (short, mid, and long wavelength) is emitted coincidently as a light having a chromaticity value near the blackbody locus and a color rendering index greater than 80.

    摘要： A light emitting apparatus includes a source of light (17); a down conversion material (12) receiving the emitted light, and converting the emitted light into transmitted light and backward transmitted light; and an optic device (14a, 14b) configured to receive the backward transmitted light and transfer the backward transmitted light outside of the optic device. The source (17) of light is a semiconductor light emitting diode, a laser diode or a resonant cavity light emitting diode. The down conversion material includes one of phosphor or other material for absorbing light in one spectral region and emitting light in another spectral region. The optic device, or lens, includes light transmissive material.
