摘要：

A simple and effective method for larger area flexible and relatively uniform phosphor film layer for blue chip-based white LED is presented in this paper. Besides having a certain ultraviolet resistance and thermal stability, the proposed yttrium aluminum garnet (YAG) phosphor film also achieved applicable color temperature (T-c of 5480 K and 4900 K), color rendering index (CRI of 68.4 and 70) and luminous efficiency (121.7 and 77 lm/W) when simply assembled with single blue chip and high-power COB separately. The preparation process and its test results suggested flexible phosphor film consists of YAG phosphor particles and common silicone without additional converter devices, which has positive practical significance for the packaging of remote phosphor-converted white LEDs.
