Abstract

A lighting device (1) comprising at least one light source (5), at least one base (7) thermally and electrically operationally connected to the light source (5), and at least one bulb fitting (10, 27) provided for receiving the base (7). The base (7) has at least one first heat transfer surface (15) and the bulb fitting (10, 27) has at least one second heat transfer surface (17) in contact with the first heat transfer surface (15) either directly or by way of a foil (16). At least one device (14, 26, 32, 39) is provided for exerting a predefined press force between the first heat transfer surface (15) and the second heat transfer surface (17).
