temperature, quenching and aging-prone, so luminous efficiency. In addition, potting materials and high temperature thermal stability of the phosphor is also problematic. Size of the phosphor used in more than 1um, refractive index greater than or equal to 1.85, while the silica refractive index is generally 1.5. Since the refractive index mismatch between the two, and the phosphor light scattering particle size is much larger than the limit (30nm), which in the light scattering surface of the
