Phosphor efficiency is the size of its particles have a close relationship with the industry to use the phosphor diameter of 5μm ~ 15μm. Studies have shown that relatively more coarse particles, the relatively higher luminous efficiency, but on the other hand, the more coarse the phosphor particles in the system, the easier the process of sedimentation in the use of time is not easy to control. Difficult to precipitate phosphor particles smaller, but its relatively low light efficiency. To this end, in order to solve the phosphor efficiency and precipitation contradictory, we can reduce the use of time, increasing the density of glue and other methods for coarse sediment is not easy to increase phosphor LED luminous efficiency.
