Abstract: A lighting assembly is disclosed which includes a leadframe and at least one light-emitting diode (LED) element arranged on the leadframe. At least a portion of the leadframe is covered with a polyurethane coating arranged to electrically insulate the portion of the leadframe, and at least a portion of the polyurethane covered portion of the leadframe is further covered with a thermally conductive material. A method for manufacturing the lighting assembly is also disclosed.

Abstract: An LED lamp includes a metal lead frame strip (14) on which is directly mounted bare LED dies (12), such as in series. Therefore, there is excellent thermal conductivity to the lead frame (14). Lenses (24) are then molded over the LED dies (12) to encapsulate them. The lead frame (14) is then inserted into a mold for a thermally conductive plastic body (38) and is bent in an arc while in the mold so that the top surfaces of the LED dies (12) are not parallel to each other. The plastic body is molded, and the structure is removed from the mold. The curved lead frame causes the overall light emission to be very wide, such a greater than 270 degrees. In another embodiment, the lead frame strip is supported over a curved outer surface of a pre-molded plastic support. Ends of the lead frame strip are inserted into electrical connectors of the plastic support.
