phosphor particles, reducing the light efficiency. Through the incorporation of nano-silica gel phosphor, the refractive index increased to 1.8 or more can reduce the light scattering and improve the optical efficiency LED (10% -20%), and can effectively improve the quality of light and color.
The traditional way is to phosphor phosphor coating and potting mix, then coated on the chip. The phosphor coating can not be precisely controlled thickness and shape, leading to inconsistent color of lig
