I-Bowling Green Municipal Utilities kancane kancane ishintsha amalambu asemgwaqweni wedolobha, ukukhathala okukodwa ngesikhathi.
Kusukela ngawo-1980, i-BGMU isebenzise izibani zomoya we-sodium ezinengcindezi ephezulu. Eminyakeni yamuva nje, insiza kanye nedolobha bahlangane ukuze banqume indlela ephumelela kakhulu yokuguqula uhlelo lokukhanyisa futhi banquma ukuhlola ama-LED, noma ama-diode akhipha ukukhanya. Ngemuva kokushintsha kokuhlola okungaba yi-100 kanye nempendulo enhle yabahlali, i-BGMU yaqala ukufaka esikhundleni sawo wonke amalambu emigwaqo angasebenzi ngoJanuwari.
"Sibheka njengephrojekthi yesikhathi eside," kusho uJeff White, umphathi wesistimu kagesi ye-BGMU. “Ngeke sivele siphume siyoshintsha imidlalo ukuze sishintshe imidlalo. … Kungasithatha iminyaka eyi-10 kuye kweyi-12.”
Izibani ze-LED ziwonga amandla, zidinga ukulungiswa okuncane futhi zihlala isikhathi eside. Abashi njengezibani ze-incandescent; kunalokho, ukukhanya kancane kancane kuyafiphala. Ziphinde zihlotshaniswe nokucisha ukukhanya okumbalwa, ukuzizwisa kwamakhasimende okuthuthukisiwe nokukhanya okuqondisayo okwengeziwe, ngokusho kuka-White.
Kunezindleko ezimbili zedolobha zikagesi: amanzi asetshenzisiwe kanye nenkokhelo yokutshala imali yezindleko zalowo mshini. Ukutshalwa kwezimali akushintshi, kodwa amandla azokwehla, ngokusho kuka-Greg Meredith, umqondisi we-Bowling Green Public Works.
“Kulungele wonke umuntu,” kusho uMeredith ngalo msebenzi. "Isikhathi eside, kuzokwenza umehluko omkhulu."
Njengoba ama-LED enza ukukhanya okuqondisayo, anamandla okunciphisa ukungcoliswa kokukhanya. Kodwa amanye amadolobha azokwengeza izibani ezengeziwe ngokonga kwezindleko ezihlobene nama-LED, ngaleyo ndlela ehluleka ukunciphisa ukungcoliswa kokukhanya, ngokusho kwe-International Dark Sky Association. Idolobha lase-Bowling Green lizogcina inani elifanayo lezibani.
URichard Gelderman, uprofesa wesayensi yezinkanyezi kanye nefiziksi waseWestern Kentucky University kanye nomqondisi weHardin Planetarium, ukholelwa ukuthi kunethuba elibalulekile ledolobha lokuthuthukisa indawo yalo yokukhanyisa.
"Izibani ze-LED, uma zifakwe ukuze zikhiqize ukukhanya okufanayo nezibani zasemgwaqweni ezishintshayo, azikwazi nje ukusindisa idolobha inani elikhulu lemali kodwa futhi zinciphisa ukungcoliswa kokukhanya," kusho uGelderman. “Ukukhanyisa okuklanywe kabi kungaba yihlazo ngempela. Le yimidlalo ezohlala isikhathi eside.”
Ukuze uthole imiphumela engcono kakhulu, izibani ze-LED kumele zibe umbala olungile futhi zifakwe ezintweni ezisebenza kahle.
Kunezinhlobo ezimbili zamalambu e-LED asakazwa kabanzi, okuhlanganisa amanye amalambu “aluhlaza okwesibhakabhaka” kanye nezibani ezimhlophe ezithambile. Ukukhanya okuluhlaza okwesibhakabhaka kwamaza amafushane kuhlakazeka kude emkhathini kunokukhanya okubomvu kwamaza amade noma ukukhanya okuphuzi okucebile, uma kwenzeka kuma-incandescent.
Ama-LED aluhlaza "ngokuvamile agcina enza isimo sibe sibi kakhulu" ngezindlela eziningi, kusho uGelderman. Ubalule isizathu esifanayo abantu belulekwa ukuthi bangasebenzisi amafoni noma amaphilisi kusihlwa - noma okungenani bacime amalambu aluhlaza emishinini yabo - ngoba kungathinta isigqi se-circadian. Ukungcola okukhanyayo kuphazamisa nemijikelezo yezilwane zasendle ezivusa ubuthongo futhi kuvimbela abantu ukuba balunguze esibhakabhakeni ebusuku.
Umphathi Jikelele we-BGMU uMark Iverson uveze ukuthi insiza izofaka ama-LED athambile ukuvikela le nkinga. "Sizama ukuqaphela ama-lumens, nombala okhanyayo ophuma kuwo," kusho u-Iverson.
Mayelana nezinto ezilungiswayo, i-BGMU izogcina izibani ezintsha zifane nabangaphambi kwayo ngangokunokwenzeka, kuhlanganise nezibani zokuhlobisa.
Ekhempasini ye-WKU kanye nangasephaseji i-Operation PRIDE ku-Cemetery Road, kukhona izinto ezikhanyayo ezibukeka njengamagilobhu engilazi yokuhlobisa. Bayisibonelo salokho okungafanele ukwenze, ngokusho kukaGelderman.
"Ziyizibonelo ezimbi kakhulu zokukhanyisa, ngoba zibeka ukukhanya okukhulu emoyeni njengoba ziphansi lapho kudingeka khona," kusho uGelderman. “Akufanele sikhokhele ukukhanya okungayi lapho okufanele kuhambe khona.”
"Kudingeka ngaphezulu kwalawo magilabhu wengilazi kunokufakwa okuvamile," esho, kodwa i-BGMU ayihleli ukususa izici zokuhlobisa. “Ngeke sifake into engahambisani nobuhle. ... Empeleni, okuwukuphela kwento eshintshayo ukukhanya kwe-bulb okuyiwona wokukhanya wangempela."
I-BGMU inethemba lokuthuthukisa ukukhanya ngenkathi ijabulisa amakhasimende, futhi "impendulo iwukuthi abantu bathanda ukukhanya," kusho u-Iverson.
