The lamp (L) has a power LED (10) connected at ends of electric power cables (30). The power LED is assembled on a tubular heat sink (20) surrounding the ends of the electric power cables. The heat sink is partially filled with a resin (50) comprising electrical insulator property, where the resin surrounds the ends of the electric power cables. The heat sink is a hollow rigid cylindrical element made of a metal heat conducting material, where an external wall of the heat sink is equipped with wings (200) that are made of a metal. |
