LEDs yog Lub Teeb Emitting Diodes: cov khoom siv hluav taws xob uas hloov hluav taws xob ncaj qha mus rau hauv lub teeb los ntawm kev txav ntawm electrons hauv cov khoom siv diode.LEDs yog qhov tseem ceeb vim tias, vim lawv qhov ua tau zoo thiab kev siv hluav taws xob tsawg, lawv tau dhau los ua qhov hloov pauv rau feem ntau cov teeb pom kev zoo.
Lub Nto Mounted Device (SMD) LED yog 1 LED ntawm lub rooj tsav xwm hauv Circuit Court, uas tuaj yeem nyob nruab nrab ntawm lub zog lossis lub zog qis thiab tsis tshua muaj siab rau cov cua sov tsim dua li COB (Chips On Board) LED.SMD LEDs feem ntau yog mounted rau ntawm Printed Service Board (PCB), ib lub rooj tsav xwm Circuit Court rau cov LEDs yog soldered mechanically.Thaum siv cov LEDs me me nrog lub zog loj, cov cua sov faib rau ntawm PCB no tsis zoo.Nws yog qhov zoo dua los siv lub zog nruab nrab ntawm LED nyob rau hauv rooj plaub no, vim tias cov cua sov yog ces zoo dua faib ntawm LED thiab lub rooj tsav xwm hauv Circuit Court.Lub rooj tsav xwm Circuit Court yuav tsum yog li ntawd poob cua sov.Qhov no yog ua tiav los ntawm kev tso lub PCB ntawm ib qho txhuas profile.Cov khoom lag luam zoo LED teeb pom kev zoo muaj ib qho txhuas profile nyob rau sab nraud kom qhov kub thiab txias kom txias lub teeb.Cov kev hloov pauv pheej yig dua yog nruab nrog lub hnab yas, vim cov yas yog pheej yig dua li aluminium.Cov khoom no tsuas yog muab cov cua kub zoo los ntawm LED mus rau lub hauv paus phaj.Yog tias aluminium tsis poob qhov cua sov no, qhov txias tseem muaj teeb meem.
Lub lumen ib watt (lm / W) piv qhia txog kev ua haujlwm ntawm lub teeb.Qhov siab dua tus nqi no, lub zog tsawg dua yuav tsum tsim kom muaj qee yam teeb pom kev zoo.Thov nco ntsoov yog tias tus nqi no raug txiav txim siab rau lub teeb ci lossis lub teeb ci tag nrho lossis rau cov LEDs siv hauv nws.LEDs lawv tus kheej muaj tus nqi siab dua.Ib txwm muaj qee qhov poob hauv kev ua haujlwm, piv txwv li thaum tsav tsheb thiab optics siv.Qhov no yog vim li cas vim li cas LEDs yuav muaj qhov tso zis ntawm 180lm / W, thaum cov zis rau lub luminaire tag nrho yog 140lm / W.Cov neeg tsim khoom yuav tsum tau hais txog tus nqi ntawm lub teeb los yog lub luminaire.Cov zis ntawm lub luminaire muaj qhov tseem ceeb tshaj qhov tso zis ntawm lub teeb, vim LED luminaires raug soj ntsuam tag nrho.
Lub zog tseem ceeb qhia txog kev sib raug zoo ntawm lub zog nkag thiab lub zog siv los ua kom lub LED ua haujlwm.Tseem muaj qhov poob hauv LED chips thiab tsav tsheb.Piv txwv li, 100W LED teeb muaj PF ntawm 0.95.Hauv qhov no, tus neeg tsav tsheb xav tau 5W ua haujlwm, uas txhais tau tias 95W LED lub zog thiab 5W tsav lub zog.
UGR stands rau Unified Glare Rating, lossis tus nqi glare rau lub teeb ci.Qhov no yog xam tus nqi rau cov degree ntawm luminaire blinding thiab yog ib qho tseem ceeb rau kev ntsuam xyuas kev nplij siab.
CRI lossis Xim Rendering Index yog ib qho kev ntsuas rau kev txiav txim siab seb cov xim ntuj raug pom los ntawm lub teeb ntawm lub teeb, nrog rau tus nqi siv rau lub teeb halogen lossis incandescent.
Standard Deviation Color Matching (SDMC) yog ib chav ntsuas ntawm cov xim sib txawv ntawm cov khoom sib txawv hauv cov teeb pom kev zoo.Xim kam rau ua yog qhia nyob rau hauv txawv Mac-Adam cov kauj ruam.
DALI sawv cev rau Digital Addressable Lighting Interface thiab siv rau hauv kev tswj lub teeb.Hauv ib lub network lossis kev daws teeb meem nyob ib leeg, txhua qhov haum tau faib nws qhov chaw nyob.Qhov no tso cai rau txhua lub teeb tuaj yeem nkag mus rau tus kheej thiab tswj tau (on - off - dimming).DALI muaj 2-xaim tsav uas khiav sib nrug ntawm lub hwj chim mov thiab tuaj yeem nthuav dav nrog cov lus tsa suab thiab lub teeb pom kev ntawm lwm yam.
Tus qauv LB tau hais ntau ntxiv hauv cov teeb qhia tshwj xeeb.Qhov no muab qhov qhia tau zoo ntawm qhov zoo, ob qho tib si ntawm lub teeb rov qab thiab LED tsis ua haujlwm.Tus nqi 'L' qhia txog tus nqi ntawm lub teeb rov qab tom qab lub neej.L70 tom qab 30,000 teev ua haujlwm qhia tias tom qab 30,000 teev ua haujlwm, 70% ntawm lub teeb tseem nyob.Ib qho L90 tom qab 50,000 teev qhia tias tom qab 50,000 teev ua haujlwm, 90% ntawm lub teeb yog sab laug, yog li qhia qhov zoo dua.Tus nqi 'B' kuj tseem ceeb.Qhov no cuam tshuam rau feem pua uas yuav txawv ntawm L tus nqi.Piv txwv li, qhov no yuav yog vim qhov tsis ua haujlwm ntawm LEDs.L70B50 tom qab 30,000 teev yog qhov tshwj xeeb heev.Nws qhia tau tias tom qab 30,000 teev ua haujlwm, 70% ntawm tus nqi tshiab lub teeb tawm, thiab qhov siab tshaj plaws ntawm 50% sib txawv ntawm qhov no.Tus nqi B yog nyob ntawm qhov xwm txheej phem tshaj plaws.Yog tias tus nqi B tsis tau hais, B50 yog siv.PVTECH luminaires yog ntsuas L85B10, uas qhia tau hais tias qhov zoo ntawm peb cov luminaires.
Cov cuab yeej ntsuas hluav taws xob lossis cov ntsuas pom pom yog qhov sib xyaw ua ke zoo heev los siv nrog LED teeb pom kev zoo, vim tias lawv tuaj yeem qhib thiab tawm ncaj qha.Hom teeb pom kev zoo no zoo tagnrho rau hauv chav tsev, lossis chav dej, tab sis nws kuj tuaj yeem siv rau ntau qhov chaw ua haujlwm thiab cov tsev khaws khoom uas tib neeg ua haujlwm.LED teeb feem ntau raug sim kom muaj sia nyob 1,000,000 lub sijhawm hloov pauv, uas yog qhov zoo rau kev siv ntau xyoo.Ib lub tswv yim: nws yog qhov zoo dua los siv lub ntsuas hluav taws xob sib cais ntawm lub luminaire, vim tias lub teeb pom kev zoo yuav kav ntev dua li lub sensor.Tsis tas li ntawd, lub sensor puas tuaj yeem tiv thaiv kev txuag nyiaj ntxiv.
Kev ua haujlwm kub yog qhov cuam tshuam loj rau lub neej ntawm LEDs.Qhov kev pom zoo ua haujlwm kub nyob ntawm qhov xaiv txias, tsav tsheb, LEDs thiab vaj tse.Ib chav tsev yuav tsum raug txiav txim tag nrho, tsis yog nws cov khoom sib cais.Tom qab tag nrho, qhov 'tsis muaj zog txuas' tuaj yeem yog tus txiav txim siab.Qhov kub thiab txias ib puag ncig zoo tagnrho rau LEDs.Cov cua txias thiab khov khov yog qhov tsim nyog tshwj xeeb, vim tias LEDs tuaj yeem tshem tawm cov cua sov kom zoo.Txij li thaum cov cua sov tsawg dua twb tsim nrog LED dua li cov teeb pom kev zoo, cov cua txias yuav xav tau lub zog tsawg dua los tswj nws qhov kub thiab txias.Qhov xwm txheej yeej-yeej!Nyob rau hauv ib puag ncig sov, qhov xwm txheej yuav txawv.LED teeb pom kev zoo feem ntau muaj qhov kub siab tshaj plaws ua haujlwm ntawm 35 ° C, PVTECH teeb pom kev zoo mus txog 65 ° C!
LEDs muaj lub teeb tsom teeb pom kev zoo, tsis zoo li cov teeb pom kev zoo uas nthuav tawm lub teeb ntawm nws ib puag ncig.Thaum LED luminaires tau muab nrog cov reflectors, ntau lub teeb nyob rau hauv nruab nrab ntawm lub beam tawm hauv lub cev tsis tau txawm los rau hauv kev sib cuag nrog lub reflector.Qhov no txo qhov degree ntawm modulation ntawm lub teeb beam thiab tuaj yeem ua rau qhov muag tsis pom.Lenses pab coj yuav luag txhua lub teeb ntawm lub teeb tawm los ntawm LED.
