Cov neeg siv khoom feem ntau nug thaum nug: "Koj lub teeb pom kev LED puas yog DC-powered lossis AC-powered?" Cov lus nug zoo li yooj yim, tab sis nws cuam tshuam ncaj qha rau kev teeb tsa tus nqi, kev ruaj ntseg system, thiab kev saib xyuas ntev ntev -. Tom qab ntau tshaj kaum xyoo hauv txoj kev- lub teeb xa tawm, Kuv tau ua haujlwm ze nrog cov kws ua haujlwm hauv lub Hoobkas thiab qhov chaw ua haujlwm. Niaj hnub no kuv mam li qhia meej tias LED txoj kev teeb lub teeb tau ua li cas thiaj li tuaj yeem zam qhov teeb meem tshwm sim.
Basic Power Supply Principles of LED Street Lights
LED yog ib qho khoom siv semiconductor uas yuav tsum tau tsav los ntawm cov tam sim no ncaj qha kom tawm lub teeb ruaj khov. Ib txwm siv hluav taws xob los yog lub teeb fluorescent tuaj yeem khiav ncaj qha ntawm AC, tab sis LEDs tsis tuaj yeem. Hais lus nruj me ntsis, LED chips lawv tus kheej ib txwm ua haujlwm ntawm DC. Qhov sib txawv tiag tiag yog nyob rau hauv seb lub luminaire muaj ib qho ua tau - nyob rau hauv tsav tsheb thiab seb lub sab nraud interface yog tsawg -voltage DC los yog siab -voltage AC.
Mainstream LED txoj kev teeb nyob rau hauv kev ua lag luam poob rau hauv ob pawg: AC- cov khoom siv hluav taws xob nrog cov tsav tsheb sab hauv, thiab qis -voltage DC fixtures uas yuav tsum tau muaj hluav taws xob sab nraud. Kev nkag siab txog qhov sib txawv ntawm ob txoj hauv kev no pab koj xaiv txoj kev daws teeb meem rau txhua qhov project.
Nta thiab Qhov Zoo ntawm DC-Powered LED Street Lights
DC fais fab mov feem ntau txhais tau hais tias lub luminaire yog tsav ncaj qha los ntawm qhov qis -voltage DC qhov chaw (feem ntau 12 V lossis 24 V). Qhov kev teeb tsa no nquag siv nyob rau hauv hnub ci txoj kev teeb, tawm - kab sib chaws, thiab qee yam ntse - tswj cov haujlwm.
Cov txiaj ntsig tseem ceeb yog qhov tseeb: tsawg zog - theem hloov dua siab tshiab thiab ua kom zoo dua tag nrho; tsis tshua muaj hluav taws xob kom muaj kev nyab xeeb zoo dua thiab txo kev pheej hmoo ntawm hluav taws xob poob lossis hluav taws; yooj yim tam sim no hloov kho kom meej dimming thiab ntse tswj. Nyob rau hauv lub hnub ci tshuab, DC fais fab tuag kuj tshem tawm cov theem inverter, ntxiv txo qhov poob.
Txawm li cas los xij, DC systems muaj kev txwv. Tsis tshua muaj hluav taws xob txhais tau hais tias tam sim no siab dua, yog li ntev - txoj hlua txuas txuas ua rau pom cov kab poob thiab yuav tsum muaj cov cables tuab dua lossis luv dua. Ib qho ntxiv DC fais fab module lossis lub hnub ci maub los yog xav tau, uas ua rau cov nqi hluav taws xob nce ntxiv.
Daim ntawv thov ntawm AC-Powered LED Street Lights
AC-powered LED txoj kev teeb muaj tus tsav tsheb sab hauv uas hloov cov hluav taws xob loj (220 V lossis 380 V) rau hauv DC tam sim no rau cov chips LED. Qhov no yog qhov kev xaiv tseem ceeb rau txoj kev hauv nroog, chaw ua si, thiab feem ntau cov haujlwm ua haujlwm.
Qhov txiaj ntsig loj tshaj plaws yog kev teeb tsa yooj yim- cov khoom siv tuaj yeem txuas ncaj qha rau hauv kab sib chaws yam tsis muaj zog ntxiv - cov khoom siv hloov pauv, thiab xaim ua raws li cov qauv teeb pom kev zoo. Kev saib xyuas tsuas yog tsom rau ntawm lub luminaire nws tus kheej, ua kom tag nrho cov nqi qis dua. Cov neeg tsav tsheb niaj hnub no los ntawm cov tuam txhab muaj npe nrov tam sim no suav nrog ntau dua -voltage, tshaj -tam sim no, thiab kev tiv thaiv surge, ua tau zoo tswj cov kab sib hloov pauv.
Tau kawg, AC systems koom nrog kev hloov pauv hloov pauv, thiab qhov zoo thiab cov cua sov ntawm tus neeg tsav tsheb ncaj qha cuam tshuam rau tag nrho cov khoom siv lub neej. Nyob rau hauv cov cheeb tsam uas muaj hluav taws xob loj viav vias, kev tiv thaiv tsav tsheb tsis txaus tuaj yeem ua kom lub zog ntawm LED nti. Yog li ntawd, thaum xaiv cov khoom, nco ntsoov xyuas tus tsav tsheb hom, kev tiv thaiv nta, thiab cov ntaub ntawv xeem.
Yuav Ua Li Cas Xaiv Txoj Kev Siv Hluav Taws Xob Zoo rau Koj Qhov Haujlwm
Tsis yog ob txoj hauv kev zoo tshaj plaws hauv ntiaj teb - qhov kev txiav txim siab nyob ntawm daim ntawv thov. Rau cov phiaj xwm ruaj khov hauv nroog thiab kev ncua ntev ntawm txoj kev loj, AC - cov tswv yim LED txoj kev teeb feem ntau yog yooj yim dua rau kev teeb tsa thiab kev saib xyuas. Rau hnub ci tawm- cov kab hluav taws xob, cov dimming meej, lossis ntse- tswj cov haujlwm, qis-voltage DC cov kev daws teeb meem feem ntau tsim nyog.
Txawm hais tias qhov kev xaiv, tus tsav tsheb zoo tseem tseem ceeb heev. Tus neeg tsav tsheb zoo ruaj khov hloov daim phiaj lossis lub roj teeb hluav taws xob mus rau qhov zoo tam sim no rau LEDs thaum muab cov cua kub zoo thiab kev tiv thaiv. Qhov no ncaj qha cuam tshuam rau lumen depreciation thiab tsis ua hauj lwm tus nqi. Hauv cov phiaj xwm xa tawm tiag tiag, peb tau pom ntau qhov ua tsis tiav thaum ntxov uas tsis yog los ntawm LED chips lawv tus kheej tab sis los ntawm kev sib raug zoo lossis tsis zoo - tsav tsheb zoo thiab cov khoom siv hluav taws xob.
Thaum xaiv, qhia meej txog qhov project lub zog, kev tswj cov kev xav tau, kev teeb tsa kev ncua deb, thiab kev tu lub peev xwm, tom qab ntawd lees paub nrog tus neeg muag khoom cov khoom siv hluav taws xob cov khoom siv hluav taws xob, qib kev tiv thaiv tsav tsheb, thiab cov ntaub ntawv xeem. Qhov no pab tiv thaiv kev sib raug zoo lossis teeb meem txog kev ua neej tom qab.
