panorama concerning the Smart Lighting
state of art. Every meeting, in English,
has examined with great scientific and
analytic rigor every micro theme.
The first lecture was given by Prof. Matteo
Meneghini (University of Padova) concerning “Reliability of High Power LEDs: from
gradual to catastrophic failure”, short
seminar on the last generation LED sources reliability, durability and decay of the
phosphorous. Probably a little suggestive
theme, but very important for CLM, for a
correct diffusion, very interested in Smart
Lighting and to understand how it works
and how this complex source functionality changes during its lifetime. Following,
there were two seminars concerning LED
sources Reliability, in parti cular, conditions as street tunnels and a predictive
analysis on sources Lifetime. The second
day started very early, as usual, and was
full of information and speculation on dynamic lighting quality and control in high
frequency places, such as hotel, resort
or, more common, urban streets. During
this session were illustrated the latest
researches concerning dynamic lighting,
its emotional and functional control by
the guest, following two main factors: the
light variation during the day and the sensation that it gives, in certain hours.
Recent researches, directly from the producers and scientists, demonstrates that
the approach correctness, if artificial light,
in inner spaces, follows collaborates with
the daytime light, officer productiveness
and wellbeing is improved. So the delay,
between indoor and outdoor lighting and
the consequent difficulty of our homeostatic balance for a long staying under
artificial lighting, would be cancelled.
This long day study was concluded by
three speeches, different themes but consequential as researches. The first one by
Josep Carreras (IREC - http://ledmotive.

lighting; the second one by Günther Leising (http://www.lumitech.at/index.php/
