Artificial light at a crossroads during the International Year of Light

Prof. Dr. Christopher Kyba, Helmholtz-Zentrum Potsdam, Deutsches GeoForschungsZentrum

For centuries, increases in the luminous efficiency of lamps have resulted in corresponding increases in light use, rather than energy savings. This has resulted in an exponential growth of light pollution, to the point where true night no longer occurs in most of Europe. Will LEDs be the final nail in the coffin for the night, or will they allow us to save energy and bring the stars back over our cities? This talk will touch on concepts and results from remote sensing, lighting design, physiology of vision, biology, ecology, energy economics, and lighting policy, in order to discuss the role of LEDs in the Energiewende, and in the worldwide transition to sustainable and healthy lighting.
