Packaged semiconductor light emitting devices having multiple optical elements
Abstract:
Methods of packaging semiconductor light emitting devices include providing a substrate having the semiconductor light emitting device on a front face thereof. A first optical element is formed from a first material on the front face proximate the semiconductor light emitting device. A second optical element is formed from a second material, different from the first material, over the semiconductor light emitting device and the first optical element. The first optical element and/or the second optical element are formed by compression molding the respective optical element.
