Tom qab ntau tshaj li kaum xyoo hauv kev lag luam txawv teb chaws - pib nrog siab - siab sodium teeb thiab tam sim no tsom mus rau tag nrho LED txoj kev teeb pom kev zoo daws teeb meem - ib qho ntawm cov lus nug uas kuv hnov feem ntau los ntawm cov neeg yuav khoom txawv teb chaws yog: "Koj lub teeb puas tuaj yeem ua tau raws li cov qauv teeb pom kev hauv zos?" Ntau tus neeg siv khoom tsis paub txog qhov kev faib hauv nroog hauv Suav teb li cas lossis qhov teeb pom kev zoo npaum li cas thiab qhov sib npaug ntawm txhua qib. Hnub no kuv yuav piav qhia meej txog peb theem tseem ceeb-txoj kev hauv plawv (xws li txoj kev loj), txoj kev thib ob, thiab txoj kev hauv cheeb tsam/txoj kev-raws liStandard for Lighting Design of Urban Road(CJJ 45 series). Qhov no yuav tsum pab koj sib txuas lus zoo dua thaum hais lus thiab kev sib tham txog kev thov.
Txoj Kev Qib Kawm Li Cas Nrog Cov Teeb Pom Kev Zoo
Txoj kev hauv nroog tau muab faib ua peb qib rau lub cev muaj zog- teeb pom kev zoo hauv tsheb: txoj kev nthuav dav thiab cov hlab ntsha, txoj kev thib ob, thiab txoj kev hauv cheeb tsam (thaj chaw). Cov qauv teeb pom kev zoo ua raws li kev faib tawm tib yam. Cov ntsuas ntsuas tseem ceeb suav nrog txoj kev nruab nrab- qhov pom ntawm qhov chaw (lossis nruab nrab luminance), qhov pom kev sib xws (lossis tag nrho cov teeb pom kev zoo sib xws thiab qhov ntev ntev), kev txwv qhov ci, thiab ib puag ncig piv. Tus qauv muab ob qho tib si tus nqi siab dua thiab tus nqi qis dua. Lub nroog nruab nrab thiab me me, lossis txoj kev uas muaj qhov zoo-tsim tsim kev tswj tsheb thiab chaw sib cais, feem ntau txais yuav tus nqi qis dua. Cov chaw hauv nroog, thaj chaw ua lag luam, txoj kev ua koob tsheej, lossis siab -chaw tsheb yuav muaj nqi ntau dua.
Qhov nruab nrab illuminance cov duab yog raws li asphalt pavement; rau kev ua vaj tse pob zeb, cov nqi yuav raug txo los ntawm 30%. Tag nrho cov nuj nqis yog tswj hwm qhov tseem ceeb, yog li kev saib xyuas yuav tsum tau siv rau hauv kev tsim.
Illuminance thiab Uniformity Requirements rau Arterial Roads (xws li Expressways)
Txoj kev Arterial thiab kev nthuav dav yog nyob rau hauv chav kawm teeb pom kev zoo tshaj plaws. Qhov nruab nrab illuminance yog 20/30 lx, sib haum rau qhov nruab nrab luminance ntawm 1.5 / 2.0 cd / m². Yam tsawg kawg illuminance uniformity UE yog 0.4, tag nrho luminance uniformity Uo yog 0.4, thiab longitudinal uniformity UL yog 0.7. Qhov siab tshaj qhov pib pib nce TI yog 10%, thiab qhov tsawg kawg ib puag ncig SR yog 0.5.
Nyob rau hauv kev xyaum, txoj kev arterial nqa ntau dua speeds thiab hnyav tsheb. Cov neeg tsav tsheb xav tau cov ntaub ntawv qhia txog kev taug kev kom pom tseeb dua thiab pom qhov ntev dua. Kev sib txuam tsis txaus ua rau qhov kaj thiab tsaus nti ua rau pom kev qaug zog thiab tuaj yeem ua rau kev txiav txim tsis raug. Ntawm ob peb txoj haujlwm arterial peb tau muab rau cov teb chaws Asia thiab Middle East, cov neeg siv khoom pib tsuas yog tsom rau kev teeb pom kev zoo. Cov kev ntsuas tom qab tau pom tias muaj kev sib txuam tsis sib xws, uas ua rau muaj nqi ntau dua. Peb mam li hais rau LED luminaires nrog lub teeb pom kev zoo dua thiab nruj nreem xam tus ncej qhov sib nrug thiab qhov siab mounting, uas thaum kawg tau ua raws li kev ruaj ntseg.
Illuminance thiab Uniformity Requirements for Secondary Roads
Txoj kev thib ob tsim cov kev sib txuas nruab nrab ntawm txoj kev hlab ntsha thiab cov kev hauv zos. Qhov nruab nrab illuminance yog 15/20 lx, nrog nruab nrab luminance ntawm 1.0 / 1.5 cd / m². Yam tsawg kawg illuminance uniformity UE yog 0.4, tag nrho luminance uniformity Uo yog 0.4, thiab longitudinal uniformity UL yog 0.5. Qhov siab tshaj plaws thawj zaug TI tseem tshuav 10%, thiab qhov tsawg kawg nkaus SR yog 0.5.
Kev thauj mus los ntawm txoj kev thib ob yog qhov nruab nrab, tseem yuav tsum muaj kev nyab xeeb yooj yim thiab pom kev nplij siab. Ntau txoj kev thib ob yog ciam teb los ntawm cov khw lossis cov chaw nyob, yog li teeb pom kev zoo yuav tsum ua haujlwm rau ob lub tsheb thiab cov neeg taug kev nyob ib puag ncig. Hauv kev sib tham ua lag luam, cov neeg siv khoom feem ntau nug seb puas tuaj yeem txo hwj chim ntxiv. Kev txo hwj chim ib leeg tsis txaus; uniformity yuav tsum tau reccalculated nyob rau tib lub sij hawm. Kev txo hwj chim thaum cia qhov sib xws poob qis dua 0.3 ua rau pom qhov tshwm sim tsis zoo thiab ua rau muaj kev pheej hmoo ntawm kev tsis txaus siab tom qab.
Illuminance thiab Uniformity Requirements for Local (Branch) Roads
Cov kev hauv zos yog qhov qis tshaj lub cev muaj zog- qib tsheb. Qhov nruab nrab illuminance yog 8/10 lx, sib haum rau qhov nruab nrab luminance ntawm 0.5/0.75 cd / m². Yam tsawg kawg illuminance uniformity UE yog 0.3, thiab tag nrho luminance uniformity Uo yog 0.4; longitudinal uniformity feem ntau tsis raug cai. Qhov siab tshaj plaws thawj zaug TI yog so rau 15%.
Kev nrawm thiab ntim qis dua, yog li tus qauv tsis nruj. Txawm li cas los xij, ntau txoj kev hauv zos coj ncaj qha mus rau thaj chaw nyob, qhov chaw uas cov neeg taug kev kev nkag siab ntawm kev nyab xeeb tseem ceeb. Qee qhov haujlwm thawb illuminance ze rau qis qis kom txuag tau tus nqi, tsuas yog tsim kom muaj kev tsis txaus siab ntawm cov neeg nyob hauv ntau qhov ntxoov ntxoo thaum hmo ntuj. Peb pom zoo kom ua kom zoo ib yam li qhov ua tau zoo thaum qhov teeb pom kev tsawg kawg nkaus tau ntsib -tshwj xeeb yog yooj yim nrog LED qhov chaw uas nws lub teeb faib tau nruj tswj tau.
Tswv yim kev paub thiab cov ntsiab lus saib
Cov qauv raug kho; site tej yam kev mob tsis yog. Pavement khoom, ncej qhov siab, luminaire lub teeb faib, thiab txij nkawm lub voj voog tag nrho cuam tshuam rau kev ua tau zoo kawg. Export tej yaam num kuj yuav tsum account rau hauv zos huab cua, voltage fluctuation, thiab installation tus cwj pwm. Ntawm ob peb txoj haujlwm African thiab South American, cov neeg ua haujlwm hauv zos tau saib xyuas me ntsis rau lub kaum sab xis, ua rau kom tsis sib xws poob qis. Tom qab ntawd peb kaw lub kaum sab xis thiab ncej- qhov sib txawv ntawm qhov sib txawv rau hauv cov duab kos thiab cov ntawv qhia kev teeb tsa thiab muab daim ntawv lees paub yooj yim; rework tus nqi poob ceeb heev.
Nco ntsoov tias cov cheeb tsam kev sib tshuam yuav tsum muaj teeb pom kev zoo dua -arterial- mus rau -arterial kev sib tshuam yuav ncav cuag 30/50 lx. Txoj kev taug kev thiab tsis yog- txoj kev tsav tsheb ua raws cov txheej txheem cais thiab tsis tuaj yeem siv lub cev muaj zog- cov nqi tsheb.
Tom qab xyoo dhau los hauv kev lag luam no, kuv tau pom tias kev piav qhia cov qauv kom meej meej yog qhov tseem ceeb tshaj qhov tsuas yog muab tus nqi qis tshaj. Thaum tus neeg siv khoom nkag siab txog qhov yuav tsum tau ua, lawv muaj feem ntau yuav paub txog tus nqi tiag tiag thiab ntev - kev ntseeg siab ntawm kev tsim kho kom zoo.
Yog tias koj tab tom ua haujlwm ntawm txoj kev txawv teb chaws - qhov project teeb pom kev zoo lossis xav tau cov txheej txheem hloov kho raws li cov cai hauv zos, xav xa cov qib kev, hom pavement, thiab kwv yees qhov sib nrug ntawm tus ncej. Peb tuaj yeem muab illuminance xam thiab luminaire cov lus pom zoo kom haum rau koj cov xwm txheej thiab pab koj kom tsis txhob muaj kev cuam tshuam tsis tsim nyog.
