Abstract
A lighting assembly, a light source and a luminaire are provided. The lighting assemblycomprises a primary thermal layer, a plurality of Lighting Emitting Diode assembliesand a plurality of wires. The primary thermal layeris of a thermally conductive material. The wiresare electrically coupled between electrodesof at least two different Light Emitting Diode assemblies. The Light Emitting Diode assembliescomprise a sub-mount, a first and a second metal electrodeand a Light Emitting Diode die. The sub-mountis of a thermally conductive and electrically insulating ceramic. The sub-mounthas a first side which is thermally coupled to the primary thermal layerand has a second side being opposite the first side. The first and the second metal electrodeare arranged at the second side of the sub-mount. The Light Emitting Diode dieis electrically and thermally coupled with an anode of the Light Emitting Diode to the first metal electrode and with a cathode of the Light Emitting Diode to the second metal electrode.
