Planujemy zadłużyć się na kolejne 12 milionów na program oświetlenia miasta.
Plusy:
- zapewne niewątpliwe oszczędności
- część pożyczki na modernizację można spłacić z tych oszczędności
Minusy:
- kolejny dług
- zupełnie niedawno czytałem, że inspekcja w jednym z brytyjskich hrabstw zwróciła uwagę na negatywne skutki stosowania oświetlenia ledowego. Jak znajdę, to wrzucę.
No i proszę:
1. LED lights can permanently damage the retina and disturb natural sleep rhythms, according to a health watchdog. Officials have said the maximum limit of our exposure to these lights should now be revisited. A new 400-page report by the French Agency for Food, Environmental and Occupational Health and Safety (ANSES) has warned that powerful LED lights are ‘photo-toxic.’ The ‘blue light’ can lead to ‘irreversible loss of retinal cells and diminished sharpness of vision,’ the watchdog warned.

2. A new generation of LED streetlights could disrupt people's sleep and even damage their eyesight, Public Health England has warned.
Hundreds of thousands of streetlights have been switched over to LEDs because they are cheaper to run and result in lower emissions.
However Public Health England warned that many people find them "uncomfortable" and said that in the long term they could that they could even "cause damage to the retina of the eye".
It also raised concerns about the increasing use of LED lights on new cars, suggesting that
they risked dazzling oncoming drivers - especially if they are elderly.
The concerns were raised by Public Health England in the Chief Medical Officer's annual report

3. New LED streetlights could damage eyesight and disrupt sleep, warns Public Health England
'Disruption of the circadian system can have a major impact on sleep quality and daytime alertness, which in turn impacts wellbeing and safety.
It is a bit like having permanent jet lag'
New streetlights installed on British roads could harm people’s eyesight and disrupt their sleep, Public Health England (PHE) has warned.
Councils across the country hope replacing existing bulbs in streetlights with new light-emitting diodes (LEDs) will help save money and reduce emissions.
Authorities in London, Gloucestershire, Lancashire, Cheshire and Dundee, among others, have spent millions of pounds upgrading their lights.
Mr O’Hagan warned against installing the new lights “purely on the basis of energy efficiency and cost”, which he said could make objects appear to jump, rather than move smoothly.
“The light spectrum may be enriched in the blue, which may be beneficial for keeping drivers alert, but many people will find the light uncomfortable.
could make objects appear to jump, rather than move smoothly,” he added.
Councils could avoid this by using LED lights which emit warm-coloured light, particularly in densely populated areas, he said.
Local authorities must also consider the effect the different frequency of the new bulbs will have on people, according to PHE.
The new lights could make objects appear to jump, rather than move smoothly, PHE warned. !!!
“Some people seem to be very sensitive to this light modulation, resulting in headaches migraine and less specific feelings of malaise,” the report added.

Ja tylko mam nadzieję, że ktoś weźmie to pod uwagę zanim wywali się 12 milionów na oświetlenie, które
1. could make objects appear to jump, rather than move smoothly
2. could harm people’s eyesight and disrupt their sleep
3. resulting in headaches migraine and less specific feelings of malaise
4. could damage eyesight and disrupt sleep, warns Public Health England
5. cause damage to the retina of the eye
Retina:
Siatkówka (łac. retina) – część oka, która jest elementem odbierającym bodźce wzrokowe. Jest specyficznej budowy błoną znajdującą się wewnątrz gałki ocznej, na jej tylnej powierzchni. Znajdują się w niej III z IV neuronów drogi wzrokowej (I- pręciki i czopki, II-kom. dwubiegunowe, III kom. wielobiegunowe)
