摘要

The light has an electrical lamp (2) and a wind turbine that are mounted on a shaft (1). The wind turbine comprises a wind wheel (3) for generating electric current for a power source of the lamp. The shaft is formed from a hollow tube or a hollow box profile, and comprises an intake port and an exhaust opening. The wheel is arranged inside the shaft and comprises a helical rotor blade that is arranged on a rotatable shaft. The wind turbine is coupled to a generator. A solar module (8) is arranged on the shaft to supply additional electric current to the power source of the lamp.
