LEDs yog dab tsi thiab lawv ua haujlwm li cas?
LEDsawv raulub teeb emitting diode.LED teeb pom kev zoo cov khoom tsim teeb pom kev zoo txog li 90% ntau dua li cov teeb pom kev zoo.Lawv ua haujlwm li cas?Cov hluav taws xob tam sim no dhau los ntawm microchip, uas ua rau pom lub teeb me me uas peb hu ua LEDs thiab qhov tshwm sim yog pom lub teeb.Txhawm rau tiv thaiv cov teeb meem kev ua haujlwm, cov khoom siv hluav taws xob LEDs tau nqus rau hauv lub dab dej kub.
Lub neej ntawm cov khoom siv teeb pom kev zoo LED
Lub neej muaj txiaj ntsig ntawm cov khoom siv teeb pom kev zoo LED tau txhais txawv dua li ntawm lwm qhov chaw teeb pom kev zoo, xws li incandescent lossis compact fluorescent teeb (CFL).LEDs feem ntau tsis "kub tawm" lossis ua tsis tiav.Hloov chaw, lawv tau ntsib 'lumen depreciation', nyob rau hauv qhov ci ntawm LED dims maj mam dhau sijhawm.Tsis zoo li cov qij incandescent, LED "lub neej" yog tsim los ntawm kev kwv yees thaum lub teeb tso zis txo qis los ntawm 30 feem pua.
Yuav siv LED li cas hauv teeb pom kev zoo?
LEDs tau muab tso rau hauv qhov muag teev thiab cov khoom siv rau kev siv teeb pom kev zoo.Me me, LEDs muab lub sijhawm tsim tshwj xeeb.Qee qhov kev daws teeb meem LED teeb yuav lub cev zoo ib yam li cov teeb pom kev zoo thiab zoo dua qhov zoo ntawm cov teeb pom kev zoo.Qee lub teeb pom kev zoo ntawm LED yuav muaj LEDs ua rau hauv lub teeb ci mus tas li.Kuj tseem muaj kev sib xyaw ua ke uas tsis yog ib txwm siv "lub teeb" lossis hloov lub teeb pom kev zoo siv thiab tsim tshwj xeeb rau cov khoom siv tshwj xeeb.LEDs muab lub sijhawm zoo rau kev tsim kho tshiab hauv cov teeb pom kev zoo thiab haum rau qhov dav dav ntawm kev siv dua li cov khoom siv teeb pom kev zoo.
LEDs thiab Kub
LEDs siv cov dab dej kub kom nqus cov cua sov uas tsim los ntawm LED thiab dissipate nws mus rau ib puag ncig ib puag ncig.Qhov no ua rau LEDs los ntawm overheating thiab hlawv tawm.Kev tswj cua sov feem ntau yog ib qho tseem ceeb tshaj plaws hauv kev ua tau zoo ntawm LED hla nws lub neej.Qhov siab dua qhov kub ntawm cov LEDs ua haujlwm, lub teeb nrawm dua yuav degrade, thiab luv dua lub neej yuav siv tau.
LED cov khoom siv ntau yam tshwj xeeb ntawm cov dab dej kub tsim thiab kev teeb tsa los tswj cov cua sov.Niaj hnub no, kev nce qib hauv cov ntaub ntawv tau tso cai rau cov tuam txhab tsim cov qij LED uas phim cov duab thiab qhov ntau thiab tsawg ntawm cov khoom siv hluav taws xob.Tsis hais txog ntawm lub dab dej kub tsim, txhua yam khoom siv LED uas tau txais ENERGY STAR tau raug sim los xyuas kom meej tias lawv tswj cov cua sov kom zoo kom lub teeb tso tawm kom zoo los ntawm qhov kawg ntawm nws lub neej ntsuas.
LED teeb pom kev sib txawv li cas rau lwm qhov chaw teeb pom kev zoo, xws li incandescent thiab Compact Fluorescent (CFL)?
LED teeb pom kev sib txawv ntawm incandescent thiab fluorescent nyob rau hauv ntau txoj kev.Thaum tsim tau zoo, LED teeb pom kev zoo dua, ntau yam, thiab kav ntev dua.
LEDs yog "kev taw qhia" lub teeb pom kev, uas txhais tau hais tias lawv tawm lub teeb nyob rau hauv ib qho kev taw qhia, tsis zoo li incandescent thiab CFL, uas emit lub teeb thiab kub nyob rau hauv tag nrho cov kev taw qhia.Qhov ntawd txhais tau hais tias LEDs tuaj yeem siv lub teeb thiab lub zog zoo dua hauv ntau daim ntawv thov.Txawm li cas los xij, nws kuj txhais tau hais tias kev tsim vaj tsev tsim nyog yuav tsum tau tsim kom muaj lub teeb ci LED uas ci ntsa iab hauv txhua qhov kev taw qhia.
Cov xim LED muaj xws li amber, liab, ntsuab, thiab xiav.Txhawm rau tsim lub teeb dawb, cov xim sib txawv LEDs tau ua ke los yog npog nrog cov khoom siv phosphor uas hloov cov xim ntawm lub teeb mus rau lub teeb uas paub "dawb" siv hauv tsev.Phosphor yog cov khoom siv daj uas npog qee qhov LEDs.Cov xim LEDs tau dav siv los ua teeb liab teeb thiab teeb pom kev zoo, zoo li lub zog khawm ntawm lub computer.
Hauv CFL, ib qho hluav taws xob tam sim no ntws ntawm electrodes ntawm txhua qhov kawg ntawm lub raj uas muaj roj.Cov tshuaj tiv thaiv no ua rau ultraviolet (UV) lub teeb thiab kub.Lub teeb UV yog hloov mus rau hauv lub teeb pom kev thaum nws tawm tsam phosphor txheej ntawm sab hauv ntawm lub teeb.
