Abstract: Phosphor-converted LED side reflectors disclosed herein comprise pigments that are photochemically stable under illumination by light from the pcLED. The pigments absorb light in at least a portion of the spectrum of light emitted by the first phosphor converted LED. The side reflector may also comprise light scattering particles and/or air voids. The pigments, light scattering particles and/or air voids may be homogeneously distributed in the reflector. Alternatively the side reflector may be layered, with the pigments, light scattering particles and/or air voids inhomogeneously distributed in the reflector. The side reflector may comprise phosphor particles.
