Kev dhia dej tob rau hauv ntu teeb pom kev zoo ntawm LED qhia nws qhov kev nkag mus ntau dhau ntawm kev siv sab hauv tsev xws li tsev thiab tsev, nthuav dav rau sab nraum zoov thiab tshwj xeeb teeb pom kev zoo. Ntawm cov no, LED txoj kev teeb pom kev zoo sawv tawm raws li daim ntawv thov raug pom zoo rau kev loj hlob muaj zog.
Inherent Advantages ntawm LED Txoj Kev Teeb Pom Kev
Cov teeb pom kev zoo li qub feem ntau yog siv cov hluav taws xob siab sodium (HPS) lossis mercury vapor (MH) teeb, uas yog cov thev naus laus zis paub tab. Txawm li cas los xij, piv rau cov no, LED teeb pom kev zoo muaj ntau yam zoo:
Environmentally Friendly
Tsis zoo li HPS thiab mercury vapor teeb, uas muaj cov tshuaj lom neeg xws li mercury xav tau tshwj xeeb pov tseg, LED fixtures muaj kev nyab xeeb dua thiab muaj kev nyab xeeb dua, tsis muaj teeb meem zoo li no.
Siab Controllability
LED txoj kev teeb ua haujlwm ntawm AC / DC thiab DC / DC lub zog hloov pauv kom muab qhov xav tau qhov hluav taws xob thiab tam sim no. Thaum qhov no ua rau muaj kev cuam tshuam hauv Circuit Court, nws muaj kev tswj tau zoo dua, ua kom nrawm nrawm rau / tawm, dimming, thiab hloov xim xim kub - qhov tseem ceeb rau kev siv lub tshuab hluav taws xob ntse ntse. Yog li ntawd, LED txoj kev teeb yog qhov tseem ceeb hauv cov phiaj xwm hauv nroog ntse.
Kev siv hluav taws xob tsawg
Cov kev tshawb fawb qhia tau hais tias txoj kev teeb pom kev zoo feem ntau suav txog kwv yees li 30% ntawm lub nroog cov peev nyiaj siv hluav taws xob hauv nroog. Kev siv hluav taws xob tsawg ntawm LED teeb pom kev zoo tuaj yeem txo qhov kev siv nyiaj ntau heev. Nws tau kwv yees tias kev siv thoob ntiaj teb ntawm LED txoj kev teeb tuaj yeem txo CO₂ emissions los ntawm ntau lab tons.
Zoo heev Directionality
Txoj kev teeb pom kev zoo ib txwm muaj tsis muaj kev taw qhia, feem ntau ua rau lub teeb pom kev tsis txaus hauv thaj chaw tseem ceeb thiab tsis xav tau lub teeb pom kev zoo hauv thaj chaw tsis yog lub hom phiaj. LED teeb, nrog rau lawv cov kev taw qhia zoo dua, kov yeej qhov teeb meem no los ntawm kev teeb pom kev thaj chaw tsis cuam tshuam rau thaj chaw ib puag ncig.
High Luminous Efficiency
Piv rau HPS lossis mercury vapor teeb, LEDs muaj kev ua haujlwm zoo dua qub, lub ntsiab lus ntau dua lumens ib chav tsev ntawm lub zog. Tsis tas li ntawd, LEDs tso tawm qis dua infrared (IR) thiab ultraviolet (UV) hluav taws xob, uas ua rau muaj hluav taws xob tsawg thiab txo cov thermal stress ntawm lub fixture.
Extended Lifespan
LEDs muaj npe nrov rau lawv cov kev ua haujlwm siab kub thiab kev ua haujlwm ntev. Hauv txoj kev teeb pom kev zoo, LED arrays tuaj yeem kav ntev txog 50,000 teev lossis ntau dua - 2-4 zaug ntev dua HPS lossis MH teeb. Qhov no txo qis qhov xav tau kev hloov pauv ntau zaus, ua rau muaj kev txuag nyiaj ntau hauv cov khoom siv thiab cov nqi kho mob.
Ob Txoj Kev Loj Loj hauv LED Txoj Kev Teeb Pom Kev
Muab cov txiaj ntsig tseem ceeb no, qhov loj me me ntawm LED teeb pom kev hauv nroog teeb pom kev zoo tau dhau los ua qhov tseeb. Txawm li cas los xij, qhov kev hloov kho thev naus laus zis no sawv cev ntau dua li qhov yooj yim "hloov" ntawm cov khoom siv teeb pom kev zoo - nws yog kev hloov pauv nrog ob qhov tseem ceeb:
Txoj Kev 1: Ntse Teeb pom kev zoo
Raws li tau hais dhau los, LEDs 'kev tswj hwm muaj zog ua rau muaj kev tsim cov tshuab hluav taws xob ntse txoj kev teeb pom kev zoo. Cov tshuab no tuaj yeem hloov kho teeb pom kev zoo raws li cov ntaub ntawv ib puag ncig (xws li lub teeb pom kev zoo, tib neeg kev ua haujlwm) yam tsis muaj kev cuam tshuam los ntawm phau ntawv, muab cov txiaj ntsig tseem ceeb. Tsis tas li ntawd, cov teeb pom kev zoo, uas yog ib feem ntawm kev sib txuas hauv nroog hauv nroog, tuaj yeem hloov mus rau hauv cov ntse IoT ntug nodes, suav nrog cov haujlwm zoo li huab cua thiab huab cua zoo saib xyuas kom ua lub luag haujlwm tseem ceeb hauv nroog ntse.
Txawm li cas los xij, qhov kev sib tw no tseem ua rau muaj teeb meem tshiab rau LED txoj kev tsim teeb pom kev zoo, yuav tsum muaj kev sib koom ua ke ntawm cov teeb pom kev zoo, lub zog hluav taws xob, kev hnov lus, tswj, thiab kev sib txuas lus ua haujlwm nyob rau hauv qhov chaw tsis muaj zog. Standardization dhau los ua qhov tseem ceeb los daws cov teeb meem no, cim qhov tseem ceeb thib ob.
Txoj Kev 2: Standardization
Standardization pab txhawb seamless kev koom ua ke ntawm ntau yam technical Cheebtsam nrog LED streetlights, ho txhim kho qhov system scalability. Qhov kev sib cuam tshuam ntawm kev ua haujlwm ntse thiab kev tsim qauv ua rau muaj kev hloov pauv txuas ntxiv ntawm LED txoj kev teeb pom kev zoo thiab kev siv.
Evolution ntawm LED Streetlight Architectures
ANSI C136.10 Tsis-Dimmable 3-Pin Photocontrol Architecture
Tus qauv ANSI C136.10 tsuas yog txhawb nqa tsis-dimmable tswj architectures nrog 3-pin photocontrols. Raws li LED thev naus laus zis tau dhau los, kev ua haujlwm siab dua thiab kev ua haujlwm tsis muaj zog tau nce ntxiv, xav tau cov qauv tshiab thiab cov qauv tsim, xws li ANSI C136.41.
ANSI C136.41 Dimmable Photocontrol Architecture
Qhov no architecture tsim raws li 3-pin kev twb kev txuas los ntawm kev ntxiv cov teeb liab tso zis terminals. Nws ua kom muaj kev sib koom ua ke ntawm cov phiaj xwm hluav taws xob nrog ANSI C136.41 photocontrol systems thiab txuas lub zog hloov mus rau LED tsav tsheb, txhawb nqa LED tswj thiab hloov kho. Cov qauv no yog rov qab-tshaj nrog cov kab ke ib txwm muaj thiab txhawb kev sib txuas lus wireless, muab kev daws teeb meem zoo rau cov teeb pom kev zoo.
Txawm li cas los xij, ANSI C136.41 muaj kev txwv, xws li tsis muaj kev txhawb nqa rau cov tswv yim sensor. Txhawm rau hais txog qhov no, lub koom haum kev lag luam teeb pom kev lag luam thoob ntiaj teb Zhaga tau qhia txog Zhaga Phau Ntawv 18 tus qauv, suav nrog DALI-2 D4i raws tu qauv rau kev sib txuas lus tsheb npav tsim, daws teeb meem kev teeb tsa thiab kev sib koom ua ke yooj yim.
Zhaga Phau Ntawv 18 Dual-Node Architecture
Tsis zoo li ANSI C136.41, tus qauv Zhaga decouples lub hwj huam mov chav tsev (PSU) los ntawm photocontrol module, tso cai rau nws los ua ib feem ntawm LED tsav tsheb los yog ib qho kev sib cais. Qhov no architecture ua rau lub dual-node system, qhov twg ib qho txuas mus rau sab saud rau photocontrol thiab kev sib txuas lus, thiab lwm yam txuas rau downwards rau sensors, tsim ib tug ua tiav ntse streetlighting system.
Zhaga / ANSI Hybrid Dual-Node Architecture
Tsis ntev los no, ib qho kev sib xyaw ua ke sib xyaw ua ke ntawm ANSI C136.41 thiab Zhaga-D4i tau tshwm sim. Nws siv 7-pin ANSI interface rau sab saud nodes thiab Zhaga Phau Ntawv 18 kev sib txuas rau downward sensor nodes, simplifying thaiv thiab leveraging ob tus qauv.
Xaus
Raws li LED txoj kev teeb pom kev zoo hloov zuj zus, cov neeg tsim khoom ntsib ntau txoj kev xaiv kev xaiv. Standardization ua kom muaj kev sib koom ua ke ntawm ANSI- lossis Zhaga-raws li cov khoom siv, ua kom tsis muaj kev hloov kho dua tshiab thiab ua kom yooj yim rau kev taug kev mus rau qhov ntse dua LED txoj kev teeb pom kev zoo.
