In recent year, main research direction in LED technology is improving lighting performance of white LED (CRI and lumen output). In this paper, effect of YAG:CE particle size on lighting performance of Multi-chip White LED (MCW-LEDs) is considered like an innovative method for improving their lighting performance. Main approaches of this work are: 1) using MCW-LEDs with high color temperature (CCT) near 8500 K, 2) investigating and demonstrating the effect of YAG:CE particle size on lighting performance of Multi-chip White LED with CCT 8500 K. Firstly, the phosphor layer mechanism of real MCW-LEDs with flat silicone coating is simulated by using LightTools 8.1.0 program. Then by varying YAG:CE particle size, ΔCCT, CRI and lumen output of MCW-LEDs were calculated and analyzed. The simulation and experimental results showed that ΔCCT, CRI and lumen output of MCW-LEDs of 8500 K MCW-LEDs are significantly influenced by varying YAG:CE particle size. These results can be a prospective ideal for future improving white LED manufacture.
