Abstract

A light module serves for inserting into a housing of a semiconductor lamp and comprises: a driver (2), a cooling element, a light generator, abutting the cooling element, with at least one semiconductor light source, which is electrically connected with the driver, and an optical refraction element covering the at least one semiconductor light source, wherein the refraction element is fastened on the cooling element and presses the light generator onto the cooling element. A semiconductor lamp comprises a housing open at the front into which the light module is inserted from the front side and on which the light module is fastened. A method serves for producing a semiconductor lamp, wherein at least the driver, the cooling element, the light generator and the refraction element are assembled into an individually manageable light module and the light module is then inserted into a housing. The invention is also applicable to replacement or retrofit lamps, in particular with a pin base, particularly a bipin base, e.g. to retrofit lamps for replacing halogen lamps, for example of the type MR16.
