ABSTRACT:
Provided is a silicone-sealed LED including: a LED chip, a cured silicone rubber layer which coats the LED chip, and a cured silicone resin layer which coats and seals the periphery of the cured silicone rubber layer. Also provided are a process for producing the silicone-sealed LED and a process for sealing a LED. In the silicone-sealed LED, a silicone rubber layer disposed between a silicone resin layer that represents the sealing body and a LED chip functions as a buffer layer, meaning cracks are not easily generated in the silicone resin layer that represents the sealing body, while full use is made of the excellent heat resistance, weather resistance, and color fastness of the silicone rubber and the silicone resin.
