Because the
silicone resin can be dispersed blue and near ultraviolet light, so
when compared with epoxy resin, silicone resin material because it can
inhibit the current, and short-wavelength light caused by the
degradation phenomena, and moderate decline in the speed of light
penetration.
Therefore, the application of the present, almost all of the high-power
white light LED products have been switched to silicone resins as
packaging materials, for example, because the short wavelength light by
the impact of parts, compared with 400 ~ 450nm wavelength of light ,
epoxy resin, a bit about the percentage of GDP, the silicone resin 400
~ 450nm light absorption of less than 1 percent, such a gap, making the
anti-short wavelength, the silicone resin has a relatively good
performance. |
