The longevity of the
LED, LED manufacturers have been adopting the current approach is to
change the packaging materials, while fluorescent material dispersed
within the packaging material, in particular the quality of packaging
material than traditional silicon Blu-ray, near-UV LED chip at the top
of epoxy resin packaging material could be more effectively suppress
material degradation and to reduce the speed of light penetration. As
the epoxy resin absorption wavelength of 400 ~ 450nm light percentage
of 45%, siliceous packaging materials with less than 1%, luminance half
time less than 10 thousand hours epoxy resin, silicon quality packaging
materials can be extended to four million hours or so, almost the same
design life of lighting equipment, which means no need to replace
lighting equipment during use white LED. However, silicone resin is a
high quality elastic soft material, processing of the necessary use
does not scratch the surface of siliceous resin production technology,
in addition to manufacturing process, on siliceous resin easily
attached to Fen Xie, so necessary in the future development of the
technology can improve the surface properties.
