Abstract

A semiconductor light-emitting device is disclosed. The device includes a plurality of semiconductor light sources and a driver with no galvanic isolation for operating the semiconductor light sources wherein the semiconductor light sources may be divided into at least two carriers, the carriers are applied on an electrically conductive substrate, and the driver, and current-conducting regions also provided on a surface of the carriers, are electrically insulated from the substrate.
