The light source and the electric circuit are arranged on a highly thermally conductive carrier module (10). The light source and the control module are arranged on different sides of the carrier module. A connection defined between the control module and light source includes a pressed grid (16) that is arranged on the carrier module. The pressed grid is coated with an insulating material. The light source is LED.
