Dr. Ing. Matthias Engel The environmental problem of light pollution

In his lecture, Dr. Matthias Engel addresses the environmental problem caused by the incorrect use of artificial light outdoors.
Above our cities, only a few dozen stars can be seen, whereas in a naturally dark sky, up to 4000 can be seen. In his lecture, Dr. Engel shows how environmentally friendly lighting technology can reduce negative effects and at the same time improve lighting comfort.
