Light pollution and the resulting effects on flora, fauna and people are constantly increasing. At the same time, the world's population spends around a fifth of the entire global electricity on illuminating the public space. PAPILIO is an innovative street lamp that uses an integrated wind generator to climate-neutrally generate all the energy it consumes. To reduce light pollution, it is constructed as a full-cut-off light, only emitting light downwards. Moreover, PAPILIO has an insect-friendly light spectrum and an infrared sensor, which only activates the light when it is actually needed.
