Txawm hais tias nws yog lub teeb pom kev hauv tsev niaj hnub, teeb pom kev zoo nyob hauv khw, lossis loj - thaj chaw teeb pom kev zoo hauv cov chaw tsim khoom thiab cov tsev khaws khoom, cov laj thawj tseem ceeb uas tib neeg hloov LED qhov muag teev, ntxiv rau qhov ua tsis tau zoo, feem ntau yog kev txhawj xeeb txog lawv txoj sia. Ntau tus neeg siv xav tsis thoob: yog kaum tawm txhiab teev ntawm lifespan tshaj tawm los ntawm cov tuam ntxhab rauLED qhov muag teevyog lawm? Vim li cas qee qhov muag teev nyob rau xyoo, thaum lwm tus siv tsis tau tom qab tsuas yog ib xyoos vim qhov ci ntsa iab?
Tsis zoo li ib txwm siv hluav taws xob thiab lub zog- txuag qhov muag teev, LED qhov muag teev tsis txhob hlawv sai sai; Hloov chaw, lawv maj mam ntsib lub teeb lwj thiab txo qhov ci ntsa iab. Txhawm rau kom nkag siab qhov tseeb lifespan ntawm LED qhov muag teev, koj tsis tuaj yeem saib cov lus qhia tshwj xeeb; koj yuav tsum paub qhov txawv ntawm theoretical thiab tiag lifespan. Kab lus no yuav rhuav tshem cov qauv kev ua neej nyob ntawm LED qhov muag teev, qhov tseem ceeb cuam tshuam, thiab cov tswv yim siv los txuas ntxiv lawv lub neej, pab koj kom tsis txhob muaj teeb meem thiab txo cov nqi teeb pom kev ntev -.
Dab tsi yog tus qauv lifespan ntawm LED teeb?
Cov qauv kev lag luam rau kev txiav txim siab LED teeb lub neej ntev yog L70 lub teeb lwj, uas yog qhov tseem ceeb uas ntau tus neeg siv tau yooj yim to taub. Cias muab, lub neej ntawm lub teeb ci LED tsis yog hais txog lub sijhawm nws siv rau lub teeb kom hlawv tag nrho thiab nres teeb pom kev zoo, tab sis lub sijhawm nws siv rau lub teeb ci kom lwj mus rau 70% ntawm nws qhov pib ci ntsa iab. Hauv qab no qhov ci ntsa iab, nws suav tias yog lub teeb pom kev tsis ua haujlwm thiab yuav tsum tau hloov. Qhov theoretical rated lifespan ntawm tus qauv siab - zoo nyob thiab ua lag luam LED qhov muag teev yog feem ntau ntawm 25,000 thiab 50,000 teev. Raws li 6-8 teev ntawm kev siv txhua hnub hauv tsev neeg, qhov no txhais tau tias yog 8-15 xyoo ntawm kev siv ruaj khov. Hauv cov chaw lag luam nrog 10-12 teev ntawm kev siv txhua hnub, nws tuaj yeem kav 5-10 xyoo. Muab piv rau cov roj teeb thiab lub zog txuag hluav taws xob, qhov kev ua neej nyob no yog ob peb zaug ntev dua, ua kom pom lub zog txuag thiab ua haujlwm ntev.
Yog vim li cas rau qhov txawv ntawm Theoretical thiab tiag Lifespan
Ntau tus neeg tshaj tawm tias lawv cov qij LED dim lossis poob hauv ob peb xyoos. Qhov no tsis yog vim qhov tshwj xeeb nce ntxiv, tab sis vim tias qhov theoretical lifespan yog txiav txim siab nyob rau hauv qhov chaw kuaj pom zoo ntawm qhov kub thiab txias, qhov tam sim no tsis tu ncua, thiab plua plav-dawb, av noo- ib puag ncig dawb. Txawm li cas los xij, kev siv txhua hnub suav nrog kev hloov pauv ntawm qhov kub thiab txias, av noo, hloov pauv tsis tu ncua, thiab tsis muaj cua sov dissipation, tag nrho cov uas ua rau lub teeb lwj thiab cov khoom aging, uas ua rau lub neej tiag tiag qis dua tus nqi theoretical.
Qhov qis dua, qis- nqi LED qhov muag teev qhia qhov sib txawv ntau dua. Lawv siv cov ntaub ntawv tsis zoo, muaj cov tsav tsheb tsis ruaj khov, thiab tsis muaj cov qauv siv hluav taws xob zoo. Lawv lub neej tiag tiag yuav tsawg dua ib -feem peb ntawm cov khoom zoo-, ua rau flickering, dimming, thiab burnout nyob rau hauv ib lub sij hawm luv luv.
Plaub yam tseem ceeb cuam tshuam rau LED Noob Lifespan
Thaum tshav kub kub Dissipation (Feem ntau Influencing Factor)
Kub kub yog tus naj npawb ib killer ntawm LED teeb lifespan. Yog tias cov cua sov tsim los ntawm LED nti tsis tuaj yeem ploj mus rau lub sijhawm, nws yuav ua kom lub teeb tawg sai sai. Rau txhua txhua 10-15℃nce nyob rau hauv nti hlws ris kub, lub neej ntawm lub teeb yuav raug halved. Cov qij uas muaj siab - zoo aluminium heat dissipation structures muaj cov cua sov dissipation zoo thiab ruaj khov lifespan, thaum pheej yig yas-cased qhov muag teev muaj feem xyuam rau cov cua sov thiab kev laus.
Driver Power Supply Quality
Tus tsav tsheb fais fab mov yog lub hauv paus tseem ceeb ntawm lub teeb LED, lub luag haujlwm rau stabilizing tam sim no thiab voltage. Cov khoom siv hluav taws xob tsis zoo ntawm cov neeg tsav tsheb muaj qhov hloov pauv loj tam sim no thiab tsis muaj kev tiv thaiv hluav taws xob. Ntev -lub sij hawm siab-voltage thiab overload ua hauj lwm yuav ncaj qha hlawv tawm cov LED chips los yog ua rau kom aging, uas kuj yog lub ntsiab yog vim li cas rau tsis ua hauj lwm ntxov ntawm feem ntau LED qhov muag teev. High- cov neeg tsav tsheb tam sim no zoo tuaj yeem ua kom ntev - lub sijhawm ua haujlwm ruaj khov ntawm lub teeb.
Kev ua haujlwm ib puag ncig
Cov av noo, plua plav, thiab qhov kub thiab txias- qhov chaw sib txawv yuav ua rau cov khoom siv hluav taws xob sab hauv thiab cov chips LED ntawm lub teeb. Tsawg tsawg-kev tiv thaiv LED qhov muag teev siv hauv chav ua noj, chaw ua haujlwm ntub dej, thiab qhib- huab cua ib puag ncig yog qhov ua rau luv luv vim tias ya raws thiab plua plav cuam tshuam cuam tshuam rau cov cua sov, ua rau lawv lub neej luv luv. Hauv qhov chaw qhuav, huv si sab hauv tsev, luminaire poob qis heev.
Hloov zaus
Kev hloov pauv tsis tu ncua yuav tsis ncaj qha hlawv tawm qhov muag teev LED, tab sis nws ua rau tus neeg tsav tsheb Circuit Court rov pib dua thiab nres, ua rau muaj kev kub ntxhov tam sim no. Ntev - lub sij hawm siab - zaus pib- nres kev khiav hauj lwm nrawm dua Circuit Court aging, indirect shortening tag nrho lifespan ntawm lub luminaire. Kev lag luam teeb pom kev zoo yuav tsum zam kom tsis txhob pib ntau zaus- nres kev ua haujlwm ntau li ntau tau.
Cov tswv yim tswv yim kom muaj txiaj ntsig txuas ntxiv LED teeb Lifespan
Ua ntej, ua qhov tseem ceeb siab - zoo LED qhov muag teev nrog cov qauv hluav taws xob zoo heev thiab cov tsav tam sim no tsis tu ncua. Tsis lees txais cov khoom pheej yig, qis dua, thiab tsis muaj kev ntseeg siab kom ntseeg tau tias lub neej yooj yim ntawm kev xav kho vajtse.
Qhov thib ob, tsis txhob muab kaw, kaw ib puag ncig kev teeb tsa. Cov chaw nyob hauv qhov chaw tiv thaiv kom tsis txhob muaj cua sov, ua rau muaj kev kub ntxhov thiab kev puas tsuaj rau lub teeb. Xyuas kom muaj qhov cua txaus thiab cua sov dissipation nyob ib ncig ntawm lub luminaire.
Thib peb, nyob rau hauv qhov chaw ntub thiab plua plav, xaiv qhov muag teev nrog cov kev tiv thaiv tsim nyog kom tsis txhob ya raws thiab plua plav nkag mus rau sab hauv, tiv thaiv lub voj voog thiab LED chips.
Plaub, kev lag luam teeb pom kev zoo yuav tsum muaj lub zog ruaj khov kom ntau li ntau tau, txo qis kev hloov pauv tsis tu ncua thiab txo qis kev pib pib- nres poob.
Cov ntsiab lus
Feem ntau, qhov theoretical lifespan ntawm lub siab - zoo LED teeb tuaj yeem ncav cuag 25,000-50,000 teev. Raws li kev siv hauv tsev thiab kev lag luam, nws tuaj yeem yooj yim muab teeb pom kev ruaj khov rau ntau xyoo.
