Abstract:
1. A mounting substrate for a semiconductor light emitting device comprising: a solid metal block including first and second opposing metal faces; the first metal face of the solid metal block including thereon a plurality of conductive traces that are arranged to electrically connect to at least one semiconductor light emitting device; the second metal face of the solid metal block including therein a two-dimensional array of metal heat sink posts, the two-dimensional array extending in the second metal face of the solid metal block along two different directions; wherein the first metal face also includes thereon a reflective layer; and wherein the solid metal block includes first and second through holes that extend through the solid metal block from the first face to the second face and wherein the mounting substrate further comprises first and second conductive vias in the respective first and second through holes that are insulated from the solid metal block, a respective conductive via being electrically connected to a respective one of the plurality of conductive traces.
