Kev sib piv ntawm LED Street Lights Thiab High-Pressure Sodium Teeb
Nrog rau txoj kev loj hlob sai ntawm kev lag luam thoob ntiaj teb thiab kev xav tau ntawm lub zog, kev txuag hluav taws xob thiab kev txo qis qis tau dhau los ua qhov kev txhawj xeeb tseem ceeb ntawm lub ntiaj teb, tshwj xeeb tshaj yog, kev txuag hluav taws xob yog ib feem tseem ceeb ntawm kev txuag hluav taws xob thiab txo qis emission. Kab lus no piv cov teeb meem tam sim no ntawm kev teeb pom kev hauv nroog thiab sib piv LEDs. Cov kev tsis sib xws ntawm txoj kev teeb thiab cov teeb hluav taws xob muaj zog sodium tau raug tshuaj xyuas thiab suav. Nws tau xaus lus tias kev siv cov teeb ci LED hauv kev teeb pom kev zoo tuaj yeem txuag tau ntau lub zog, thiab tuaj yeem txo qis emission ntawm ntau cov pa phem, txhim kho ib puag ncig zoo, thiab ua tiav lub hom phiaj ntawm kev txuag hluav taws xob thiab txo qis emission.
Tam sim no, cov teeb pom kev zoo hauv nroog txoj kev teeb pom kev zoo feem ntau suav nrog cov teeb pom kev siab sodium teeb thiab fluorescent teeb. Ntawm lawv, high-pressure sodium teeb yog dav siv nyob rau hauv txoj kev teeb pom kev zoo vim hais tias ntawm lawv cov high luminous efficiency thiab muaj zog pos huab nkag. Ua ke nrog cov qauv teeb pom kev zoo tam sim no, txoj kev teeb pom kev zoo nrog cov teeb pom kev siab sodium teeb muaj cov teeb meem hauv qab no:
1. Lub teeb pom kev zoo yog ncaj qha illuminating rau hauv av, thiab lub illuminance yog siab. Nws tuaj yeem ncav cuag ntau dua 401 lux hauv qee txoj kev thib ob. Obviously, qhov illuminance belongs rau over-illumination, uas ua rau ib tug loj npaum li cas ntawm hluav taws xob lub zog nkim. Nyob rau tib lub sijhawm, ntawm kev sib tshuam ntawm ob lub teeb uas nyob ib sab, lub teeb pom kev tsuas yog ncav cuag li 40% ntawm cov kev taw qhia ncaj qha, uas tsis tuaj yeem ua tau raws li qhov xav tau teeb pom kev zoo.
2. Qhov kev ua tau zoo ntawm lub teeb siab sodium teeb emitter tsuas yog kwv yees li 50-60%, uas txhais tau hais tias nyob rau hauv lub teeb pom kev, ze li ntawm 30-40% ntawm lub teeb yog illuminated nyob rau hauv lub teeb, tag nrho efficiency tsuas yog 60%, muaj yog ib qho phem phenomenon.
3. Raws li txoj cai, lub neej ntawm cov teeb hluav taws xob siab siab sodium tuaj yeem ncav cuag 15,000 teev, tab sis vim yog cov kab hluav taws xob hloov pauv thiab kev ua haujlwm ib puag ncig, lub neej kev pab cuam nyob deb ntawm lub neej theoretical, thiab qhov kev puas tsuaj ntawm cov teeb nyob rau ib xyoos yog siab tshaj 60%.
Piv nrog rau cov tsoos high-pressure sodium teeb, LED txoj kev teeb muaj cov hauv qab no zoo:
1. Raws li cov khoom siv semiconductor, nyob rau hauv txoj kev xav, lub neej zoo ntawm lub teeb LED tuaj yeem ncav cuag 50,000 teev, uas yog siab dua li 15,000 teev ntawm high-pressure sodium teeb.
2. Muab piv nrog cov teeb hluav taws xob sodium siab, cov xim rendering Performance index ntawm LED teeb tuaj yeem ncav cuag 80 lossis ntau dua, uas yog ze rau lub teeb ntuj. Raws li cov teeb pom kev zoo li no, kev paub txog kev ua haujlwm ntawm tib neeg lub qhov muag tuaj yeem siv tau zoo los xyuas kom muaj kev nyab xeeb ntawm txoj kev.
3. Thaum lub teeb hluav taws xob qhib, lub teeb hluav taws xob sodium siab xav tau txheej txheem preheating, thiab lub teeb xav tau qee lub sijhawm los ntawm kev tsaus ntuj mus rau qhov kaj, uas tsis tsuas yog ua rau lub zog hluav taws xob pov tseg, tab sis kuj cuam tshuam rau kev txhim kho kev txawj ntse. tswj. Hauv qhov sib piv, LED teeb tuaj yeem ua tiav qhov pom kev teeb pom kev zoo thaum lub sijhawm qhib, thiab tsis muaj lub sijhawm hu ua lub sijhawm pib, kom lub zog txuag hluav taws xob zoo tuaj yeem ua tiav.
4. Los ntawm kev pom ntawm lub teeb pom kev zoo, lub teeb hluav taws xob siab sodium siv mercury vapor luminescence. Yog tias lub teeb ci raug muab pov tseg, yog tias nws tsis tuaj yeem kho tau zoo, nws yuav ua rau muaj kev ua qias tuaj ib puag ncig. Lub teeb LED txais cov teeb pom kev zoo hauv lub xeev, thiab tsis muaj teeb meem rau tib neeg lub cev. Nws yog ib puag ncig tus phooj ywg lub teeb ci.
5. Los ntawm nam ntawm optical system tsom xam, illumination ntawm high-pressure sodium teeb belongs rau omnidirectional illumination. Ntau tshaj 50% ntawm lub teeb yuav tsum tau reflected los ntawm lub reflector kom illumination hauv av. Nyob rau hauv tus txheej txheem ntawm kev xav, ib feem ntawm lub teeb yuav ploj mus, uas yuav cuam tshuam rau nws txoj kev siv. Lub teeb LED yog nyob rau hauv ib txoj kev illumination, thiab lub teeb yog npaj los ncaj qha mus rau lub illumination, yog li ntawd tus nqi siv kuj siab.
6. Nyob rau hauv high-pressure sodium teeb, lub teeb faib nkhaus yuav tsum tau txiav txim los ntawm ib tug reflector, yog li muaj kev txwv loj; Nyob rau hauv lub LED teeb, ib tug faib lub teeb qhov chaw yog saws, thiab kev tsim tau zoo ntawm txhua qhov hluav taws xob lub teeb qhov chaw tuaj yeem qhia qhov zoo tshaj plaws lub xeev ntawm lub teeb ci ntawm lub teeb, paub txog kev hloov kho ntawm lub teeb pom kev zoo, tswj kev faib lub teeb, thiab ua kom lub teeb pom kev zoo sib xws nyob rau hauv lub teeb pom kev zoo ntawm lub teeb.
7. Nyob rau tib lub sijhawm, LED teeb muaj ntau qhov kev tswj tsis siv neeg ua tiav, uas tuaj yeem kho qhov ci ntawm lub teeb raws li lub sijhawm sib txawv thiab teeb pom kev zoo, uas tuaj yeem ua tiav cov txiaj ntsig zoo txuag hluav taws xob.
Nyob rau hauv cov ntsiab lus, piv nrog rau kev siv high-pressure sodium teeb rau txoj kev teeb pom kev zoo, LED txoj kev teeb yog ntau zog-npaum thiab ib puag ncig tus phooj ywg.
