Abstract
A light emitting diode (LED) is disclosed comprising a plurality of semiconductor layers with a first contact on the bottom surface of the semiconductor layers and a second contact on the top surface of the semiconductor layer. A coating is included that comprises a cured binder and a conversion material that at least partially covers the semiconductor layers, wherein the second contact extends through the coating and is exposed on the same plane as the top surface of the coating. An electrical signal applied to the first and second contacts is conducted through the coating to the semiconductor layers causing the LED to emit light. In other embodiments first and second contacts are accessible from one side of the LED. A coating is included that comprises a cured binder and a conversion material. The coating at least partially covers the semiconductor layers, with the first and second contacts extending through the coating and exposed on the same plane as a surface of the coating. An electrical signal applied to the first and second contacts is conducted through the coating to the semiconductor layers causing the LED to emit light.
