  • Ultraviolet reflective silicone compositions, reflectors, and light sources incorporating the same
    Patent number: 9203002
    Abstract: Disclosed herein are polysiloxane compositions that include a first polysiloxane and a second polysiloxane. The first and second polysiloxanes may be immiscible, and may exhibit differing refractive indices. The polysiloxane compositions may further include a curing agent and a catalyst. In some embodiments, the polysiloxane compositions significantly reflect light in at least the ultraviolet region of the electromagnetic spectrum. Reflectors and light emitting diode sources including the polysiloxane compositions are also disclosed.
    Type: Grant

  • Silicone-Grafted Core-Shell Particles, Polymer Matrix, and LED Containing Same
    Publication number: 20150014727
    Abstract: A silicone-grafted core-shell particle is described wherein the silicone-grafted core-shell particle comprises a core of an inorganic particle and a shell of a grafted poly(dimethylsiloxane) polymer formed from a bi-terminated poly(dimethylsiloxane) having reactive groups at each terminal end. The silicone-grafted core-shell particles may be dispersed in a polysiloxane polymer matrix and employed as an LED encapsulant.
