We normally think of the eye as an organ for vision, but due to the discovery of
additional nerve connections from recently-detected novel photoreceptor cells in
the eye to the brain, it is now understood how light also mediates and controls a
large number of biochemical processes in the human body. The most important
findings are related to the control of the biological clock and to the regulation of
some important hormones through regular light-dark rhythms. This in turn means
that lighting has a large influence on health, well-being and alertness.
Historic gas street lamps in cities like Berlin, Prague and Warsaw can now be upgraded to energy-saving LED technology, thanks to a solid-state retrofit designed by Berlin-based Braun Schaltgeräte & Service with
assistance from LED solutions provider Future Lighting Solutions.
Thirty-some years ago, I spent my junior year abroad studying Danish and
English literature at the University of Copenhagen. During the long, dusky
Danish winter days, the lights of Copenhagen’s specialty shops cast an
inviting glow out over the dim sidewalks. With idle hours to fill between
university classes, I often succumbed to the lure of fine design and friendly
European service, wandering from shop to shop along Copenhagen’s
winding pedestrian streets.
