Light source device and light source arrangement

A light source device (100) comprises a light source (200); coupled with a light source (200) input port (108) for supplying an input voltage; coupled with a light source (200) output terminal (108) for providing an output voltage; a first bypass port (114) and a second bypass port (114); and with the light source (200) coupled to said circuit board. The circuit board (102) has at least one conductor track (402) with the first bypass port (114) and the second bypass port (114) coupled to the light source bridging (200) performing an electric potential of the first bypass port (114) to the second bypass port (114).
