I-Bowling Green Municipal Utility itshintsha ngokuthe ngcembe izibane zesitrato zesixeko, ukudinwa kube kanye ngexesha.
Ukususela ngo-1980, i-BGMU isebenzise izibane zomoya we-sodium ezinoxinzelelo oluphezulu. Kwiminyaka yakutshanje, i-utility kunye nesixeko sadibana ukumisela eyona ndlela isebenzayo yokuguqula inkqubo yokukhanyisa kwaye yagqiba ukuvavanya ii-LED, okanye ii-diode ezikhupha ukukhanya. Emva kokutshintsha kovavanyo olumalunga ne-100 kunye nengxelo entle yabahlali, i-BGMU yaqala ukubuyisela zonke izibane zesitrato ezisilelayo ngoJanuwari.
"Siyijonga njengeprojekthi yexesha elide," kusho uJeff White, umphathi wenkqubo yombane ye-BGMU. “Asizukuphuma nje siye kutshintsha imidlalo ukuze sitshintshe imidlalo. …Inokusithatha iminyaka eli-10 ukuya kweli-12.”
Izibane ze-LED zinamandla ombane, zifuna ukulungiswa okuncinci kwaye zihlala ixesha elide. Azitshi njengezibane zokukhanyisa; endaweni yoko, ukukhanya ngokuthe ngcembe kuncipha. Zikwanxulunyaniswa nokucima kokukhanya okumbalwa, amava aphuculweyo omthengi kunye nokukhanya okuthe kratya komkhombandlela, ngokukaMhlophe.
Zimbini iindleko zesixeko zombane: amanzi ombane asetyenzisiweyo kunye nentlawulo yotyalo-mali ngeendleko zolu lungiso. Utyalo-mali alutshintshi, kodwa amanzi azakuncitshiswa, ngokutsho kuka-Greg Meredith, umlawuli we-Bowling Green Public Works.
“Ilungele wonke umntu,” utshilo uMeredith ngale projekthi. "Ixesha elide, liza kwenza umahluko omkhulu."
Ekubeni ii-LED zenza ukukhanya okubhekiselele, zinamandla okunciphisa ungcoliseko lokukhanya. Kodwa ezinye iidolophu ziya kongeza izibane ezingaphezulu kunye nokugcinwa kweendleko ezinxulumene nee-LED, ngaloo ndlela zisilela ukunciphisa ungcoliseko lokukhanya, ngokutsho kwe-International Dark Sky Association. Isixeko sase-Bowling Green siya kugcina inani elifanayo lezibane.
URichard Gelderman, uprofesa we-astronomy kunye ne-physics yeYunivesithi yaseWestern Kentucky kunye nomlawuli we-Hardin Planetarium, ukholelwa ukuba kukho ithuba elibalulekileyo lesixeko sokuphucula indawo yokukhanyisa.
"Izibane ze-LED, ukuba zifakwe ukuvelisa ukukhanya okufanayo njengoko izibane zesitrato zithatha indawo, azikwazi nje ukugcina isixeko imali eninzi kodwa zinciphisa ukungcola kokukhanya," kusho uGelderman. “Izibane eziyilwe kakubi ngenene ziya kuba lihlazo. Le yimidlalo eza kuhlala ixesha elide. ”
Ukufezekisa iziphumo ezilungileyo, izibane ze-LED kufuneka zibe ngumbala ochanekileyo kwaye zifakwe kwiindawo ezifanelekileyo.
Kukho iintlobo ezimbini zezibane ze-LED ezijikelezwe ngokubanzi, kubandakanywa izibane ezimhlophe "eziluhlaza" kunye nezibane ezimhlophe ezithambileyo. Ubude obufutshane bokukhanya okuluhlaza okwesibhakabhaka busasaza kude esibhakabhakeni kunobude obude obubomvu bokukhanya okanye ukukhanya okutyheli okutyebileyo, kwimeko ye-incandescents.
Ii-LED eziluhlaza "zihlala zisenza imeko ibe mandundu" ngeendlela ezininzi, utshilo uGelderman. Wachaza isizathu esifanayo ukuba abantu bacetyiswa ukuba bangasebenzisi iifowuni okanye iipilisi ngokuhlwa - okanye ubuncinane bacime izibane eziluhlaza kwizixhobo zabo - kuba kunokuchaphazela izingqisho ze-circadian. Ungcoliso lokukhanya lukwaphazamisana nomjikelo wokulala wezilwanyana zasendle yaye kuthintela abantu ukuba bakrobe esibhakabhakeni ebusuku.
Umphathi Jikelele we-BGMU uMark Iverson ubonise ukuba into eluncedo iyakufakela ii-LED ezithambileyo ukunqanda le ngxaki. "Sizama ukuqaphela i-lumens, kunye nombala okhanyayo ovela kuyo," kusho u-Iverson.
Ngokubhekiselele kwi-fixtures, i-BGMU iya kugcina izibane ezitsha zifana nabangaphambili bayo ngokusemandleni, kubandakanywa nezibane zokuhombisa.
Kwikhampasi ye-WKU kunye nakwipaseji ye-Operation PRIDE e-Cemetery Road, kukho izibane ezikhanyayo ezikhangeleka njengeglowubhu yeglasi yokuhombisa. Bangumzekelo wento engafanele yenziwe, ngokutsho kweGelderman.
"Yimizekelo eyoyikisayo yokukhanyisa, kuba babeka ukukhanya okukhulu emoyeni njengoko bephantsi emhlabeni apho kufuneka khona," kusho uGelderman. “Akufanelanga ukuba sihlawulele isibane esingayi apho besifanele ukuya khona.”
"Kuthatha ngaphezulu kwezo glowubhu zeglasi kunofakelo oluqhelekileyo," utshilo, kodwa i-BGMU ayicwangcisi ukususa izinto zokuhombisa. “Asizi kubeka into engahambelaniyo nobuhle. … Ngokwenene, ekuphela kwento etshintshayo sisibane sebhalbhu esisesona sibane.”
I-BGMU inethemba lokuphucula ukukhanya ngelixa ikholisa abathengi, kwaye "ingxelo kukuba abantu bathanda ukukhanya," kusho u-Iverson.
