    摘要: An arrangement for emitting mixed light including a primary and secondary radiation with at least one first electroluminescent light-source for emitting first primary radiation, at least one second electroluminescent light-source for emitting second primary radiation, and a light-converting element for absorbing at least one of the primary radiations and re-emitting the secondary radiation. The light-converting element is arranged so that the entire proportion of primary radiation in the mixed light passes through the light-converting element. The light-converting element is a ceramic light-converting material whose microstructure is selected to be such that the color point of the mixed light of primary and second radiation is substantially independent of the angle of viewing.

    摘要: A white light LED is described that uses an LED die that emits visible blue light in a wavelength range of about 450-470 nm. A red phosphor or quantum dot material converts some of the blue light to a visible red light having a peak wavelength between about 605-625 nm with a full-width-half-maximum (FWHM) less than 80 nm. A green phosphor or quantum dot material converts some of the blue light to a green light having a FWHM greater than 40 nm, wherein the combination of the blue light, red light, and green light produces a white light providing a color rendering of Ra,8>90 and a color temperature of between 2500K-5000K. Preferably, the red and green converting material do not saturate with an LED die output of 100 W/cm2 and can reliably operate with an LED die junction temperature over 100 degrees C.
