ABSTRACT:
A light-emitting device (200) has a submount (100) and a plate for heat transfer (300) having a metallic plate (30). The submount (100) has a mount base (10), at least one light-emitting diode chip (5) mounted thereon and electrically conducting lines (12-17) formed on the mount base (10) to be connected electrically to the light-emitting diode chip (5). A first plane (11) of the mount base (10) of the submount (100) is bonded thermally to the first plate (300). For example, the plate is a circuit board having a metallic plate (30), and the submount (100) is bonded thermally to the metallic plate (30) of the one of the at least one plate (300). In an example, a second plate for heat transfer is also bonded thermally to a second plane of the mount base (100) for providing a plurality of heat transfer paths.
