Abstract:
1. A light emitting diode (LED) package, comprising: a substrate; at least one LED chip on said substrate; an inner material covering said at least one LED chip; a lens covering said inner material, said lens being harder than said inner material; a first meniscus holding feature having a top surface and at least one outer side surface that faces away from said lens, said lens on said first meniscus holding feature and extending out to a falling edge defined by the intersection of said top surface and said at least one outer side surface of said meniscus holding feature, wherein a shape of said lens is at least partially defined by a meniscus formed by said first meniscus holding feature, wherein said meniscus holds the shape of said lens over said inner material; and an adhesive between said first meniscus holding feature and said lens, said adhesive holding said lens to said substrate, said adhesive disposed such that said lens and the remainder of said package can readily expand and contract even though said lens and said package may have different coefficients of thermal expansion.
