  • Abstract
    Two new multi-chip white LEDs (MCW-LEDs) structures are proposed and demonstrated, including the phosphor-quartz structure and the silicone-quartz structure. In comparison with the non-SiO2 packages, the CCT deviation can drop about 48% at most by using the proposed structures in the MCW-LEDs. The participation of about 5%~10% SiO2 can accomplish the MCW-LEDs with the improved angular color uniformity and the high lumen output optimally.
