Abstract
A light emitting device includes a radiation source operable to generate and radiate excitation energy, the source being configured to irradiate a wavelength conversion component with excitation energy and the wavelength conversion component comprising a layer of photo-luminescent material configured to emit radiation of a selected color when irradiated by the radiation source and a color enhancement filter layer configured to filter undesirable wavelengths of an emission product of the layer of photo-luminescent material to establish a final emission product for the light emitting device.
