"Cov teeb pob kws"-npe rau lawv qhov zoo sib xws rau pob ntseg pob kws- tau dhau los ua neeg nyiam nyob hauv ntau qhov chaw, suav nrog cov khw muag khoom, cov tsev lag luam, cov tshav puam thiab txoj kev, nyob rau lub sijhawm tam sim no ntawm kev siv LED teeb pom kev zoo. Lawv cov txiaj ntsig tshwj xeeb-360-degree omnidirectional illumination, kev yooj yim ntawm kev teeb tsa, thiab kev siv hluav taws xob zoo heev- yog qhov ua rau lawv nrov heev. Vim tias tam sim ntawd cuam tshuam rau cov nqi khiav lag luam, kev saib xyuas zaus, thiab kev siv nyiaj mus sij hawm ntev, kev pab cuam lub neej sawv tawm yog ib qho tseem ceeb tshaj plaws uas coj los rau hauv tus account thaum lub sij hawm kev yuav khoom thiab kev xaiv cov khoom. "Lub teeb pob kws tuaj yeem xav tau ntev npaum li cas?" yog ib lub ncauj lus uas ntau tus neeg siv khoom nquag nug. Nyob rau hauv qhov tseeb, pob kws lub teeb lub neej tsis yog tus lej teev; es, nws raug cuam tshuam los ntawm ntau yam kev hloov pauv, suav nrog kev xav txog ib puag ncig, kev tsim qauv, thiab cov khoom zoo. Kev soj ntsuam nruj me ntsis ntawm pob kws teeb lub neej kev pab cuam thiab lwm yam tseem ceeb yog muab rau hauv ntu uas ua raws li hauv qab no, tag nrho los ntawm kev xav ntawm kev lag luam kev lag luam.
Kev lag luam-Standard Rated Lifespan Thiab Theoretical Lifespan
Theoretical Upper Limit: Siab -cov chips LED zoo muaj peev xwm ua neej nyob nruab nrab ntawm 60,000 thiab 100,000 teev. Cov naj npawb no yog ua raws li cov txiaj ntsig kev ntsuas tau sau tseg hauv qhov chaw kuaj mob zoo meej, uas suav nrog cov dej ntws tsis tu ncua, qhov ntsuas kub tsis tu ncua ntawm 25 degree, thiab tsis muaj kev cuam tshuam sab nraud. Qhov theoretical siab tshaj plaws no sib haum mus rau lub neej ua haujlwm ntawm 20 txog 34 xyoo raws li 8-teev cov sijhawm noj txhua hnub, uas ntev dua li cov teeb pom kev zoo xws li cov qij incandescent (kwv yees li 1,000 teev) thiab cov raj fluorescent (kwv yees li 8,000 teev).
Kev lag luam ib puag ncig-Rated Lifespan: Lub koob npe nrov LED pob kws teeb ntawm kev lag luam kev lag luam feem ntau muaj qhov ntsuas lub neej ntawm 25,000 txog 50,000 teev. Cov qauv tam sim no rau siab- zoo, cov khoom tseem ceeb yog **50,000 teev (raws li L70 tus qauv)**. Tus qauv L70, uas qhia meej ntev npaum li cas lub teeb pom kev zoo tuaj yeem khiav ua ntej nws cov luminous flux (lub teeb tso zis) deteriorates mus rau theem qis dua 70% ntawm nws qhov pib ci ntsa iab, yog ib qho kev lag luam uas siv los ntsuas cov khoom ruaj khov. Yog li ntawd, lub fixture yog suav hais tias tau mus txog qhov kawg ntawm nws lub neej usable yog hais tias lub teeb tso zis poob los ntawm ntau tshaj 30%.
Kev sib raug zoo ntawm Lifespan thiab Warranty Coverage: Reputable brand-npe pob kws teeb feem ntau muaj ob mus rau tsib xyoos warranty. Piv txwv li, cov khoom lag luam zoo xws li Philips nquag muab nws cov khoom lag luam pob kws lub teeb pom kev zoo 5-xyoo lav, uas sib npaug rau 50,000-teev rated lifespan. Txhua qhov kev ua haujlwm tsis zoo lossis kev ua txhaum uas tsis yog qhov tshwm sim ntawm kev siv tsis raug lossis tib neeg yuam kev yog tsim nyog rau kev kho dawb lossis hloov pauv thoob plaws lub sijhawm lav no.
Cov ntsiab lus tseem ceeb cuam tshuamLED pob kws teeb'Lub neej tiag tiag
LED Chip Quality (Qhov Tseem Ceeb)
Lub pob kws lub teeb ci qhov chaw yog ua los ntawm LED chips. Reputable hom chips, zoo li Bridgelux los yog Epistar, muaj kev ruaj ntseg zoo thiab qeeb lub teeb lwj, yog li lawv lub neej tiag tiag yog ze rau cov chaw tsim khoom tus nqi. Ntawm qhov tod tes, subpar, generic chips nquag muaj ib tug xov tooj ntawm sab hauv flaws; tom qab tsuas yog ib mus rau ob xyoos ntawm kev siv, lawv yuav muaj teeb meem loj heev los yog ua tsis tiav ntxov ntxov.
Tsav Tsheb Fais Fab Khoom Zoo (Lub Bottleneck hauv Lifespan)
LED fixture lub hwj chim mov tsav tsheb feem ntau txwv nws tag nrho lifespan. High- tsav tsheb zoo tuaj yeem nyob nruab nrab ntawm 30,000 thiab 50,000 teev ua tsaug rau lawv qhov tsis tu ncua -tsim tam sim no, kub- tiv thaiv electrolytic capacitors, thiab tshaj -voltage thiab tshaj- kev nyab xeeb tam sim no. Ntawm qhov tod tes, cov tsav tsheb subpar cia siab rau cov khoom pheej yig, thiab lawv cov electrolytic capacitors yog nquag ziab tawm thiab ua tsis tiav ntawm qhov kub thiab txias. Nyob rau hauv ib xyoos los yog li ntawd, cov tsav tsheb yuav hlawv tawm, ua rau tag nrho lub teeb fixture irreparable thiab yuav tsum tau nws tag nrho cov pov tseg.
Cov Khoom Siv Vaj Tsev thiab Kev Tsim Kho Thaum Tshav Kub Kub
Vim tias LEDs yog cua sov-sensitive, lawv lub neej tseem ceeb yog txiav ib nrab rau txhua txhua 10℃nce hauv qhov kub thiab txias. Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws ntawm cov cua sov, cov teeb pom kev zoo LED pob kws siv cov txhuas-raws li PCB substrate, loj-sov- thaj chaw tshav kub dissipation fins, thiab tag nrho -aluminium enclosure. Txawm li cas los xij, cov qauv qis dua feem ntau siv nyias aluminium lossis yas- clad aluminium vaj tse; Qhov no ua rau cov cua sov tsim, uas ua rau cov khoom siv sab hauv kev laus thiab lub teeb deterioration.
Cov xwm txheej ua haujlwm hauv ib puag ncig
Kub: Kub kub (siab tshaj 45 degree) los yog txias (qis dua -20 degree) tej yam kev mob yuav txo tau lub fixture lub neej.
Humidity: Dej-cov khoom siv tiv taus (cim IP65) muab kev ua haujlwm ntev dua hauv cov chaw zoo li no vim tias corrosive lossis av noo nyob ib puag ncig tuaj yeem ua rau muaj kev puas tsuaj rau sab hauv.
Voltage: Kev hloov pauv hauv qhov hluav taws xob uas ntau dua ± 10% ntawm tus nqi nominal tuaj yeem ua rau cov khoom siv sab hauv nyob rau hauv kev ntxhov siab ntawm hluav taws xob thiab ua rau muaj kev ruaj ntseg ntawm cov khoom siv tag nrho.
Ntau zaus ntawm kev hloov thiab siv cov qauv
Cov hluav taws xob tam sim no tshwm sim los ntawm kev hloov pauv ntau zaus- tig lub teeb rau thiab tawm ob peb zaug hauv ib teev- yuav ua rau lub teeb lub neej luv luv. Tsuav kom muaj cua sov txaus, kev ua haujlwm tas mus li, txuas ntxiv -zoo li lub Hoobkas ua haujlwm nyob ib ncig ntawm lub moos- feem ntau ruaj khov dua li nquag pib- nres cycles.
Txoj hauv kev muaj tiag kom nce pob kws teeb lub neej
Ua Haujlwm Zoo Tshaj Plaws hauv Kev Xaiv: Xaiv cov khoom los ntawm cov tuam txhab txhim khu kev qha, ua kom paub tseeb lub hom ntawm LED chips thiab tsav tsheb nrog rau cov qauv cua sov, es tsis yog mus nrog tus nqi pheej yig tshaj. Muab warranty - cov khoom lag luam muaj qhov tseem ceeb.
Optimize lub installation ib puag ncig: Siv lub hwj chim tswj kev tswj kom tsis txhob muaj hluav taws xob hloov pauv; siv cov dej tsis muaj dej / siab-cov qauv ntsuas kub rau cov av noo / siab- qhov chaw kub; thiab nruab rau hauv qhov chaw qhuav, zoo- qhov cua qhov chaw uas muaj chaw txaus rau cov cua sov dissipation.
Kev Siv Tsim Nyog: Siv qhov sib txuam PWM dimmers rau cov khoom dimming los tiv thaiv kev puas tsuaj rau cov khoom; txo qis kev hloov pauv ntau zaus; siv kev poob siab-cov qauv tiv thaiv rau cov qauv uas yuav tsum tau pib nquag- nres.
Kev Kho Kom Yooj Yim Yooj Yim: Tshawb xyuas cov kev sib txuas xoob kom tsis txhob muaj cua sov los ntawm kev sib cuag tsis zoo thiab ntxuav lub teeb lub cev txhua peb mus rau rau lub hlis kom tsis txhob txhaws cov cua sov dissipation fins.
Qhov zoo, tsim, thiab kev siv ib puag ncig ua haujlwm ua ke los txiav txim siab lub teeb pob kws lub neej ntev . 50,000 xuab moos ntawm lub sijhawm ntev- teeb pom kev zoo tuaj yeem ua tiav tau yooj yim nrog txoj cai siab - cov khoom zoo, kev teeb tsa, thiab kev siv, txo qis kev hloov pauv thiab tu cov nuj nqis.
