Abstract
Lighting components and fixtures having optical elements with multiple portions are disclosed. A wavelength conversion element can be mounted over a source, the wavelength conversion element including wavelength conversion material remote to the source, such as on or near the outside surface of a conversion element. The element can be filled with a transparent and thermally conductive material which thermally couples the remote conversion material and the source, aiding in thermal dissipation and improving fixture efficacy. An optical element can be formed by using an embossing plate to form a first portion, partially curing the first portion, removing the embossing plate, and introducing material to form a second portion.
