Abstract
A light-emitting device () has a submount () and a plate for heat transfer () having a metallic plate (). The submount () has a mount base (), at least one light-emitting diode chip () mounted thereon and electrically conducting lines (-) formed on the mount base () to be connected electrically to the light-emitting diode chip (). A first plane () of the mount base () of the submount () is bonded thermally to the first plate (). For example, the plate is a circuit board having a metallic plate (), and the submount () is bonded thermally to the metallic plate () of the one of the at least one plate (). In an example, a second plate for heat transfer is also bonded thermally to a second plane of the mount base () for providing a plurality of heat transfer paths.
