| 摘 要： | 研究了配粉胶、填充胶、光参数测试设备及测试方法,对大功率仿流明式LED灯珠的色温参数变化的影响.研究结果表明:高折射率配粉胶可有效地提高LED灯珠的光通量,但产品色度稳定性较差;低折射率配粉胶的灯珠的光通量低,产品色度稳定性高;填充胶的折射率对灯珠的色温变化影响较小,同时灯珠的光通量受填充胶折射率的影响亦较小.

| Abstract: | The color temperature variation of high power white Light-emitting diodes (LED ) with phosphors silicone,filling adhesive,photoelectric tester and measurements has been investigated. The results show that the phosphors silicone with high refractive index has been improved the luminous flux with poorer color stability. On the contrary,the phosphors silicone with low refractive index has lowered luminous flux and better color stability. It has nothing of the filling adhesive refractive index on color temperature and luminous flux has been found. |

| Keywords: | light-emitting diodes (LED) refractive index of silicone color temperature |
