Because the
thermal phenomena will produce video-like epoxy resin, epoxy resin or
even short wavelength would also cause some problems, because the white
LED light spectrum, but also includes the short-wavelength light, while
the epoxy is quite easy to in the short-wavelength white LED light
damage, even if the low-power white LED has already let the damage
caused by epoxy resin, not to mention high-power white LED contained in
the short-wavelength light more, so naturally accelerate the
deterioration, and even Some of the products in a continuous light
after the life of less than 5,000 hours. |
