Abstract

An illumination device comprising a connection carrier (1), at least one light-emitting diode (10), an electrically insulating layer (3) and a fixing device (4) is specified. The connection carrier (1) has a first main area (1a) and a second main area (1b) remote from the first main area. The light-emitting diode (10) is fixed on the first main area (1a) of the connection carrier (1). The electrically insulating layer (3) is fitted to the second main area (1b) of the connection carrier (1) and projects laterally beyond the second main area (1b) of the connection carrier (1). The fixing device (4) is suitable for fixing the illumination device to a mounting area (2a) of a carrier (2), wherein the electrically insulating layer (3) is arranged between the second main area (1b) of the connection carrier (1) and the mounting area (2a) of the carrier (2). Furthermore, the fixing device (4) presses the connection carrier (1) against the mounting area (2a). The pressure exerted in this way is used to effect a fixing of the insulating layer (3) between the second main area (1b) of the connection carrier (1) and the mounting area (2a). The fixing device (4) is connected to an optical element…
