Abstract

The present invention relates to an LED lighting assembly, having a printed circuit board (2) with an LED chip (1), a heat sink (3) thermally connected with the printed circuit board (2) at one side and forming a cavity (5) at the other side for at least accommodating a non- insulation LED driver (4), wherein a thermal conduction insulating layer which is arranged between the heat sink (3) and the printed circuit board (2) consists of a first part and a second part, and wherein the first part is configured to provide a creepage distance, both the first part and the second part thermally contact the heat sink (3) and the printed circuit board (2), and the second part has a thermal conductivity higher than that of the first part. In addition, the present invention further relates to an LED retrofit lamp having the LED lighting assembly of the type above.
