description | A light-emitting diode (LED) lamp is provided that includes: an LED source coupled to a housing; and a lens over the source and coupled to the housing. The lens, or a portion of the lens, includes a plurality of glass beads, each having a metal-containing coating (e.g., a coating comprising at least one of Ni, Al, Cu, In and brass) and dispersed in a polymeric matrix (e.g., an acrylic or a polycarbonate). Further, the lens has a thermal conductivity of at least about 2 W/m*K and an optical transmissivity of at least 80%. |
