Bowling Green Municipal Utilities yog maj mam hloov lub nroog txoj kev teeb, ib qho burnout ib zaug.
Txij li thaum xyoo 1980s, BGMU tau siv cov hluav taws kub siab sodium vapor teeb. Nyob rau hauv xyoo tas los no, cov khoom siv hluav taws xob thiab lub nroog tau ntsib los txiav txim siab txoj hauv kev zoo tshaj plaws los hloov kho lub teeb pom kev zoo thiab txiav txim siab sim LEDs, lossis lub teeb-emitting diodes. Tom qab kwv yees li 100 qhov kev sim hloov pauv thiab cov lus pom zoo hauv zej zog, BGMU tau pib hloov qhov tseem ceeb ntawm txhua txoj kev tsis ua haujlwm nyob rau lub Ib Hlis.
Jeff White, tus thawj coj ntawm BGMU hluav taws xob tau hais tias "Peb saib nws yog qhov project mus sij hawm ntev." "Peb tsis yog yuav tawm mus thiab hloov cov khoom siv los hloov cov khoom siv. … Nws tuaj yeem siv sijhawm li 10 txog 12 xyoos. "
LED teeb yog lub zog txuag, xav tau kev saib xyuas tsawg dua thiab kav ntev dua. Lawv tsis hlawv tawm zoo li cov teeb ci incandescent; Hloov chaw, qhov ci ntsa iab maj mam dims. Lawv kuj tseem cuam tshuam nrog tsawg dua teeb pom kev zoo, txhim kho cov neeg siv khoom thiab ntau lub teeb pom kev, raws li Dawb.
Muaj ob lub nroog cov nqi hluav taws xob: cov wattage siv thiab cov nqi peev rau cov nqi ntawm cov khoom siv. Kev nqis peev tsis hloov pauv, tab sis wattage yuav txo qis, raws li Greg Meredith, tus thawj coj ntawm Bowling Green Public Works.
"Nws zoo rau txhua tus," Meredith hais txog qhov project. "Lub sijhawm ntev, nws yuav ua rau muaj qhov sib txawv loj."
Txij li cov LEDs tsim lub teeb pom kev, lawv muaj peev xwm txo tau lub teeb paug. Tab sis qee lub nroog yuav ntxiv teeb ntau ntxiv nrog rau kev txuag nqi nrog LEDs, yog li ua tsis tau kom txo cov teeb pom kev zoo, raws li International Dark Sky Association. Lub nroog Bowling Green yuav khaws tib lub teeb.
Richard Gelderman, Western Kentucky University astronomy thiab physics xibfwb thiab tus thawj coj ntawm Hardin Planetarium, ntseeg tias muaj lub sijhawm tseem ceeb rau lub nroog los txhim kho nws cov teeb pom kev zoo.
Gelderman tau hais tias "LED teeb, yog tias tau teeb tsa los tsim cov teeb pom kev zoo ib yam li cov teeb pom kev uas lawv hloov pauv, tsis tuaj yeem txuag lub nroog nyiaj txiag tseem ceeb tab sis kuj txo cov pa phem," Gelderman tau hais. “Kev tsim teeb pom kev tsis zoo yuav yog qhov txaj muag tiag tiag. Cov no yog cov khoom siv uas yuav nyob ntawd rau lub sijhawm ntev. "
Yuav kom ua tiav cov txiaj ntsig zoo tshaj plaws, LED teeb yuav tsum yog xim kom raug thiab ntsia hauv cov khoom siv tau zoo.
Muaj ob hom LED teeb dav dav, nrog rau cov teeb dawb "xiav" ntxiv thiab cov teeb pom kev zoo. Lub teeb xiav lub teeb luv luv tawg nyob rau hauv qhov chaw tshaj li lub teeb liab ntev lossis lub teeb daj-nplua nuj, nyob rau hauv cov ntaub ntawv ntawm incandescents.
Cov LEDs xiav "feem ntau xaus ua rau qhov xwm txheej tsis zoo" hauv ntau txoj hauv kev, Gelderman tau hais. Nws hais txog tib yam vim li cas tib neeg raug qhia kom tsis txhob siv xov tooj lossis ntsiav tshuaj thaum yav tsaus ntuj - lossis tsawg kawg tua lub teeb xiav hauv lawv cov khoom siv - vim tias nws tuaj yeem cuam tshuam rau circadian rhythms. Lub teeb muaj kuab paug kuj cuam tshuam rau lub voj voog pw tsaug zog ntawm cov tsiaj qus thiab tiv thaiv tib neeg los ntawm kev peering thaum hmo ntuj.
BGMU Tus Thawj Coj Tus Thawj Coj Mark Iverson tau qhia tias cov khoom siv hluav taws xob yuav nruab softer LEDs los tiv thaiv qhov teeb meem no. "Peb tab tom sim ua kom paub txog lub lumens, thiab lub teeb xim uas los ntawm nws," Iverson hais.
Raws li cov khoom sib tw, BGMU yuav khaws lub teeb tshiab zoo ib yam li nws cov neeg ua ntej raws li qhov ua tau, suav nrog cov teeb pom kev zoo nkauj.
Ntawm WKU lub tsev kawm ntawv thiab raws li Kev Ua Haujlwm PRIDE txoj hauv kev ntawm Txoj Kev Cemetery, muaj cov teeb pom kev zoo uas zoo li lub ntsej muag iav globes. Lawv yog ib qho piv txwv ntawm qhov tsis ua, raws li Gelderman.
Gelderman tau hais tias "Lawv yog cov piv txwv txaus ntshai ntawm cov teeb pom kev zoo, vim tias lawv tau tso lub teeb ntau npaum li huab cua thaum lawv nqis los rau hauv av uas nws xav tau," Gelderman tau hais. "Peb yuav tsum tsis txhob them rau lub teeb uas tsis mus qhov twg nws yuav tsum mus."
"Nws yuav siv sij hawm ntau dua ntawm cov iav globes dua li kev teeb tsa ntau dua," nws hais, tab sis BGMU tsis npaj yuav tshem tawm cov yam ntxwv zoo nkauj. "Peb yuav tsis tso ib yam dab tsi uas tsis haum rau qhov zoo nkauj. … Tiag tiag, tib yam uas hloov tawm yog lub teeb lub teeb uas yog lub teeb tiag tiag. "
BGMU vam tias yuav txhim kho teeb pom kev zoo thaum ua kom cov neeg siv khoom txaus siab, thiab "cov lus tawm tswv yim yog tias tib neeg nyiam lub teeb," Iverson tau hais.
