Patent ID: 8017246

Claim:
An optoelectronic device comprising: a light transmitting surface of a light emitting diode (LED); and a light transmitting protective coating of cured silicone resin on said light transmitting surface, said protective coating comprising less than about 10% of organosiloxanes having molecular weights of up to about 1000, wherein the silicone resin is formed by the process comprising: admixing a linear organopolysiloxane, an organohydrogenpolysiloxane, a substance having at least one of a phenyl and a cyclohexyl group to increase a refractive index of said cured silicone resin to at least about 1.45, and an adhesive aid for enhancing adhesion of said silicone resin to the light transmitting surface; and removing at least a portion of the organosiloxanes having molecular weights below 1000 from said linear organopolysiloxane prior to admixing to reduce discoloration of the silicone resin for improved light transmission through the silicone resin.
