Abstract:
A light emitting device comprising a substrate (6) having an electrically conducting circuit layer (8), a LED package (7) surface mounted on the substrate (6) and electrically connected to the circuit layer (8), and a heat sink element, surface mounted on the substrate (6) separately from the LED package (7), the heat sink element having a body (2) of a heat conductive material surrounding the LED package (7), the body being thermally connected to the circuit layer (8), and being adapted to provide heat dissipation from the circuit layer (8) to a surrounding environment, wherein a surface (3) of the heat sink element facing the LED package is adapted to form part of a beam shaping optics for shaping light emitted from the LED package. Since the heat sink body is in thermal contact with the circuit layer, the heat resistance from the LED package to the heat sink body via the circuit layer is minimized.
