'Packaging materials containing benzene ring will eventually happen aging'. At last Saturday 'LED technology seminar' in 2006, grew up three Ken electrical technology based LED sales department burial Kang Er said, as the high power LED packaging material, resin materials may not be able to avoid ageing problems. But it just need high power and long life, if life is about 20000 hours of products, through the resin material will not form the interface fluctuation kongfu, completely can use resin encapsulation. Otsuka said, want to make the LED lighting, such as general source, need some technical breakthroughs. Among them, the components, as a result of LED light aging, says that need to be developed to avoid the problem of packaging material. At present, the packaging material is gradually by the epoxy resin to light aging lighter silicone resin transition. But 'as long as the containing benzene ring, can't avoid color yellow gradually' ( 大冢) 。 Otsuka said that need to be further to improve the resin class encapsulation material, may eventually need no resin encapsulation using the company is discussed. However, no resin encapsulation cases due to the use of glass as a chip, but also can increase the assembly process, so you need to solve the problem of low production cost. ( Reporter: onishi male)
