I kēia mau lā, ua ʻike ʻia kahi hui noiʻi mai ke Kulanui o Exeter ma UK ma ka hapa nui o ʻEulopa, ua ʻike nui ʻia kahi ʻano pollution māmā hou me ka hoʻohana nui ʻana.LED no ke kukui o waho. Ma kā lākou pepa i paʻi ʻia ma ka puke pai Progress in Science, ua wehewehe ka hui i kā lākou noiʻi ʻana i nā kiʻi i lawe ʻia mai ka International Space Station.

Ua hōʻike ʻia nā haʻawina mua e hiki ke loaʻa nā hopena maikaʻi ʻole i nā mea hihiu a me nā kānaka. No ka laʻana, ua hōʻike ʻia ka noiʻi e ʻike nā holoholona a me nā kānaka i ka hoʻopilikia ʻana i nā ʻano moe, a nui nā holoholona i huikau i ka mālamalama i ka pō, e alakaʻi ana i kahi ʻano pilikia o ke ola.

Ma kēia noiʻi hou, ua kākoʻo nā luna mai nā ʻāina he nui no ka hoʻohana ʻanakukui LEDma nā alanui a me nā wahi kaʻa, ma mua o ka kukui sodium maʻamau. I mea e hoʻomaopopo maikaʻi ai i ka hopena o kēia hoʻololi, ua loaʻa i nā mea noiʻi nā kiʻi i lawe ʻia e nā astronauts ma ka International Space Station mai 2012 a 2013 a me 2014 a 2020. Hāʻawi kēia mau kiʻi i kahi ʻoi aku ka maikaʻi o nā hawewe māmā ma mua o nā kiʻi satellite.

Ma o nā kiʻi, hiki i nā mea noiʻi ke ʻike i nā wahi o ʻEulopa i hoʻohuli aikukui kahawai LEDa ma kahi nui, ua hoʻololi ʻia ke kukui LED. Ua ʻike lākou ua hoʻololi koʻikoʻi nā ʻāina e like me UK, Italia, a me ʻIlelani, aʻo nā ʻāina ʻē aʻe e like me Austria, Kelemānia, a me Belgium ʻaʻole i loli. Ma muli o nā hawewe like ʻole o nā kukui i hoʻokuʻu ʻia e nā LED i hoʻohālikelike ʻia me nā puʻupuʻu sodium, hiki ke ʻike maopopo ʻia ka piʻi ʻana o ke kukui polū ma nā wahi i hoʻololi ʻia i nā kukui LED.

Hōʻike ka poʻe noiʻi ua ʻike lākou he hiki i ke kukui polū ke keʻakeʻa i ka hana ʻana o ka melatonin i loko o ke kanaka a me nā holoholona ʻē aʻe, a laila e hoʻopilikia i nā ʻano moe. No laila, ʻo ka hoʻonui ʻana i ke kukui polū ma nā wahi kukui LED hiki ke loaʻa nā hopena maikaʻi ʻole i ke kaiapuni a me nā poʻe e noho ana a hana i kēia mau wahi. Manaʻo lākou e noʻonoʻo pono nā luna i ka hopena o ke kukui LED ma mua o ka holomua ʻana i nā papahana hou.
