摘要

The power generation device (1) has a housing (2), which comprises an inflow area with an inflow opening (4) and an outflow area (5) with an outflow opening (6). A repeller arrangement (19) is provided, which is stored rotary within the inflow area and another repeller arrangement is stored rotary within the outflow area. The inflow area is tapered in a flow direction (8). The outflow area of a nozzle shaped transition is extended to the outflow opening. An independent claim is also included for a lighting device for a vehicle, particularly for a bicycle.
