摘要

Lighting system comprises a housing (40) containing a lighting unit (100) with light sources (30), an electrical supply unit with an electrical energy storage unit for supplying the light sources with stored electrical energy and an energy conversion unit (1) for converting environmental energy into electrical energy and for feeding the electrical energy to the energy storage unit. Preferred Features: A twilight control unit acquires the brightness value of a surrounding light and a switching unit connects the lighting unit with the electrical energy storage unit when the brightness value is below the prescribed threshold value.
