Printed circuit board for use in e.g. lighting device, has heat dissipating element arranged in through-hole, and radiation source i.e. LED, arranged on heat dissipating element, where heat dissipating element is electrically conductive

摘要

The board (1) has a heat dissipating element (3) arranged in a through-hole (2), and a radiation source (6) i.e. LED, arranged on the heat dissipating element. The heat dissipating element is electrically conductive, and the radiation source is separated from the heat dissipating element by a heat conducting and electrically insulating layer (5), where the heat conducting and electrically insulating layer is implemented as a submount for the radiation source. The submount is pressed into the heat dissipating element.
