Light emitting diodes (LEDs) hold the promise for efficient, lightweight and environmental-friendly lighting sources, which is regarded as the next-generation lighting technology. Since so many problems still remain to be solved, this emerging technology has attracted the attention of a large number of researchers. Among several issues frequently discussed in the community, the long-time reliability...
The phenomenon that phosphor particles tend to settle in silicone is widely known. Recent researchers have discussed the effects of phosphor concentration on luminous efficacy of LED packaging. But to produce reliable products, mechanical and interfacial considerations are also essential. In this paper, the mechanical behaviors and interfacial strength of silicone with different levels of phosphor...
Among several materials used in LED packaging, phosphor-filled silicone plays an important role on optical performance and long-time reliability of the module. Many researchers have studied optical properties of phosphor, but few have considered mechanical behavior of phosphor-filled silicone. In this paper, mechanical properties of YAG phosphor-filled silicone are obtained. Tensile tests, which are...
