SP12: Specific variation and quantitive characterization of ecological, innovative lighting

The Chair of Lighting Technology at the TU Berlin (TU-Lt) researches within subproject 12 on public lighting systems on streets and the usage of innovative illuminants. Different lighting situations will be realised, varied systematically and characterized quantitatively.

Effects of a timely variable dimming of lighting scenarios on road users, inhabitants, insects or birds are hardly investigated. Therefore, this effect is being observed during research of urban lighting (integration program community) as well as during field research (integration project field). The variation of the spectrum reaches from a part-time night illumination up to a fully adaptive management with movement sensors.

These investigations base on a catalogue of requirements on ecologically-innovative illumination, being prepared in cooperation with SP06, SP07, SP08 and SP10. Its criteria also serve as a basement for the extensive planning of the experiment of the investigations in the integration projects and also for judging the results of the sub projects. The catalogue is supposed to help finding a decision on how to plan an outdoor illumination system.

Aim of SP12 is to develop a concept for an ecological-innovative street and pavement illumination. While being energy efficient and having small influence on the surrounding ecosystem, it should also provide safe illumination.
