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 or air voids. The pigments, light scattering particles, or air voids may be homogeneously distributed in the reflector. Alternatively the side reflector may be layered, with the pigments, light scattering particles, or air voids inhomogeneously distributed in the reflector. The side reflector can include phosphor particles.
