1. A light emitting device, comprising:

  • at least one single-die semiconductor light-emitting diode (LED) coupleable with a power supply to emit a primary radiation which is the same for each single-die semiconductor LED present in the device, said primary radiation being a relatively shorter wavelength radiation outside the visible white light spectrum; and

    a down-converting luminophoric medium arranged in receiving relationship to said primary radiation, and which in exposure to said primary radiation responsively emits radiation at a multiplicity of wavelengths and in the visible white light spectrum, with said radiation of said multiplicity of wavelengths mixing to produce a white light output.
