GUIDELINES FOR THE REDUCTION OF THE
LUMINANCE OF THE SKY
Bad news
As already announced on
this site come bad news on the future of
the luminance of the sky.
Astronomers said they were contrary to
the Norm CIE TC 4-21 of the current
standard Norm CIE 126.
International Astronomers say that the
new version is worse than the previous
year and does not protect astronomy.
As always stated on our website and as
confirmed by Italian astronomers and
amateur astronomers, including at the
international Elizabeth Alvarez del
Castillo and other astronomers have
expressed strong negative opinions on
lighting a LED emitting a luminous flux
in the blue too (also in white we add ).
Strong concerns were raised on the
models used by the Commission and the
cities that they would not behave as
diffusive light sources.
The Commission's responses were
generally negative.
What is most surprising, and that
surprises us in the fight against light
pollution in Italy is the certainty of
the Boards of lighting that we saw as
defeated in the "light" is a matter also
of others, it is the daily bread of
astronomers and amateur astronomers .
Know and we announced that the placing
on the market for LEDs will try to give
the final blow to astronomy and that is
why we must fight as we did for the
Italian regional laws.
ANALYSIS OF THE
MAXIMUM OF THE NORM CIE TC 4-21, ON THE
LED, ON THE GROUNDS OF ASTRONOMY
Up to now, the luminance
of the sky is governed by the standard
Norm CIE 126, 1997, in practice a rule
of thumb that divided the territory into
quality zones: dark, suburban, urban
residential and commercial and wanted to
contain the light emitted by household
with values of 0 5 10 25%! just looking
at these values in part comparable with
some allowed by the standard Italian
Norm UNI 10819, which raises the
question of protection as we speak.
Now you try to give a scientific value
to the new standard but many of the
contents or templates are rebuttable or
statements or opinions totally opposed
to those of the committee.
On energy savings we have not because it
is the dog that bites its tail and 2
times! In fact now the LED are not
comparable as the luminous efficiency
and the best lamps but have an emission
spectrum mainly in white and blue, quite
untenable for astronomy.
On the calculation of the light emitted
upward, reflecting etc.. there are
practical applications (conducted by the
AAMT Civitavecchia Roma Italy and also
featured on this site internet) have
shown that almost get the facts and no
theoretical model can be taken as a
model against a practical demonstration.
The design limitations imposed by TC
4-21 as a result of theoretical studies
is based on an R% <= 3%, then the
standard is compared to some outlaw
regional Italian law, it appears that in
very much regions of Italy can not be
applied .
In the city there are a lot of
reflections but the model of the city
diffondend is not acceptable because not
satisfactory and is contrary to the
experience, in fact the De Castillo has
refuted it and go see the pictures of
cities (see Rome photo index page of
this site internet) for practically
refute this model or the absolute
certainty of such a model.
So all this is confirmed that the
astronomical world is right, but their
commissions are appointed / technically
legalized by the institutions and the
European Commission, there is no reason
why must be the lighting or some better
lighting to determine the future world
of astronomy, the starry sky and the
environment.
It seems that the LEDs are the gospel
but cost 10 times shielded road
equipment !
Models, repeat do not count because no
clash with the experience Galilean and
the astronomers know the experience.
We invite several professors, members of
international committees in Europe and
national travel by night in the open
countryside and see how a light source
white / blue overhang and the other
spectra is annoying for the human eye
and then to Astronomy.
We agree with the decrease in the levels
of illumination but this clashes with
the policy of all lighting: lighting of
walls, monuments, churches,
archaeological sites, buildings, etc..
is this the way to decrease the
luminance of the sky?
You go to see the extent of the
luminance of the sky performed by the
observatory astronomical of the Asiago
Italy and you will see that in recent
years, the luminance of the sky has
grown exponentially!
This means that the various Norms UNI
CIE etc. who wanted to limit the
luminance of the sky have failed, a good
connoisseur short
words.

0) Carta etica celeste
La
carta etica celeste rappresenta il codice etico della popolazione mondiale, in
special modo di coloro che hanno relazioni dirette ed indirette con gli impianti
di illuminazione per esterni. Tradotta in varie lingue, ha avuto grande successo
in tutto il mondo (telegiornali nazionali, agenzie, siti internet mondiali).
Basterebbe ispirarsi ai contenuti qualitativi della carta etica celeste per
ottimizzare gli impianti di illuminazione per esterni ed abbattere l'emissione
luminosa verso la volta celeste.

Due metodi sperimentali per la misura
del flusso luminoso disperso ed R%
Due
metodi sperimentali messi a punto dall'autore: il metodo della magnitudine
stellare, il metodo del flusso disperso. Per la prima volta in Italia, con tutti
i limiti dei metodi sperimentali, č stato possibile determinare R% ed il flusso
disperso per abitante e chilometro quadrato, per una cittā di 50.000 abitanti (Civitavecchia).
