Abstract

A semiconductor lamp (1) has at least one semiconductor light source (8) arranged on a front face (7) of a substrate (6) and a driver circuit (11) for activating the at least one semiconductor light source (8), at least part of the driver circuit (11) being secured on a rear face (10) of the substrate (6), facing away from the at least one semiconductor light source (8). The invention can be used, in particular, for retrofit lamps, in particular incandescent- or halogen retrofit lamps.
