Claim 1:
2. The wavelength-conversion layer of claim 1, wherein either: (i) the first, second, and third conversion layer materials include a first wavelength-converting phosphor material, a second wavelength-converting phosphor material, and a third wavelength-converting phosphor material, each wavelength-converting phosphor material absorbing light at a first wavelength and in turn emitting corresponding down-converted light at different corresponding down-converted wavelengths, or (ii) the first, second, and third conversion layer materials include a first wavelength-converting phosphor material, a second wavelength-converting phosphor material, and a transparent material, each wavelength-converting phosphor material absorbing light at a first wavelength and in turn emitting corresponding down-converted light at different corresponding down-converted wavelengths, the transparent material being transparent at the first wavelength and emitting no down-converted light.
