Insect-friendly street lighting

Environmentally compatible illumination for the protection of species

Many insects are attracted by street lighting. Luminaires positioned side by side can even function as a kind of barrier: The insects can´t cross the street anymore and are restricted in their ability to search for food. In a cooperation with the Department of Lighting Technology at Berlin Technical University the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) intends develop a special design for street lighting which reduces the optical emission on the insects´ flight path: The light emitted by the luminaires shall no longer be visible at the luminaire itself but only on the surface of the sidewalk and the street.

The luminaires are to be tested in an experimental space and then installed and tried out in four communities for a period of two years. Subject of the evaluation is not only the insects´ behavior but also the acceptance of the residents. The joint project is being financed by the Federal Office for Nature Conservation with funds as high as 2,56 million Euro of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU).
