also called potting materials with low moisture absorption, low stress, anti-aging properties. Currently used include epoxy and silicone encapsulants. Due to high transparency silica gel, a large refractive index, thermal stability, stress is small, low moisture absorption, better than epoxy resin, high-power LED package is widely used, but the cost is higher. Studies show that increasing the refractive index can be effective in reducing the refractive index of silica physical barriers caused b
