Abstract
A mounting substrate for a semiconductor light emitting device includes a solid metal block having first and second opposing metal faces. The first metal face includes an insulating layer and a conductive layer on the insulating layer. The conductive layer is patterned to provide first and second conductive traces that connect to a semiconductor light emitting device. The second metal face may include heat sink fins therein. A flexible film including an optical element, such as a lens, also may be provided, overlying the semiconductor light emitting device.
