A retrofit lamp comprises a heat sink, a light source module with a circuit board, whose rear side lies two-dimensionally on the heat sink and at the front side of which at least one semiconductor light source is arranged, and a ring partially covering the front side of the light source module, wherein the ring presses the light source module onto the heat sink. A method serves for producing a retrofit lamp, wherein the rear side of the circuit board of the light source module is laid on the heat sink and the ring is put on the retrofit lamp from the front such that it presses the light source module onto the heat sink. The invention is particularly applicable to LED retrofit lamps for replacing conventional light bulbs or halogen lamps.
