ht emitted appears blue or yellow light side. The Lumileds has developed a conformal coating (Conformal coating) technology can achieve the uniformity of the phosphor coating to protect the uniformity of light color, as shown in Figure 3 (b). But studies show that when the phosphor coating on the chip surface directly, because the presence of light scattering, the light efficiency is low. In view of this, the United States Institute Rensselaer proposed a scattering photon extraction (Scattered P
