Sanken electric high power LED lighting resin packaging materials can not completely prevent photoaging

"Packaging materials containing benzene ring will eventually deteriorate". In the days before the meeting of the "2006 LED technology seminar, Sanken electric technology LED the business minister Otsuka Yasuji said that as a high power LED packaging materials, resin materials may not be able to avoid the problem of aging. However, this is only the case of high power and ultra long life, if the life of about 20 thousand hours of the product, through the formation of resin material will not work on the interface, you can use resin packaging. Otsuka said, in order to make LED become the general lighting light source, "need some technical breakthrough". Among them, for the LED light-emitting components caused by the phenomenon of light aging, indicating the need to develop packaging materials to avoid this problem. At present, the packaging material is gradually changing from epoxy resin to light aging phenomenon of silicone resin transition. But as long as you can not avoid the benzene ring, the color gradually yellow "(Otsuka). Otsuka said resin packaging materials need to be further improved, no resin package may eventually need to explore the use of the company is. However, the use of glass as a chip protective sleeve, but also increase the assembly process, and therefore need to address the problem of low cost.
