LED yog dab tsi? Lawv ua haujlwm li cas?
Lub ntsiab lus LED sawv cev rau Lub Teeb Emitting Diode.LED teeb pom kev zoo Cov khoom lag luam nyob ib puag ncig 90% ua haujlwm zoo dua li qhov muag teeb. Lawv ua haujlwm li cas? Tam sim no ntws hla lub microchip, igniting lub microscopic teeb qhov chaw hu ua LED, uas ua rau pom lub teeb. Txhawm rau tiv thaiv kev ua haujlwm nyuaj, lub dab dej kub nqus cov cua sov tsim los ntawm LEDs.
Lifespan ntawm LED teeb pom kev zoo khoom.
LED teeb pom kev zoo muaj lub neej sib txawv dua li lwm hom teeb pom kev zoo. LEDs feem ntau tsis "kub tawm" lossis ua tsis tiav. Hloov chaw, lawv ua siab ntev "lumen depreciation," uas yog qhov tsis tu ncua ntawm qhov ci ntawm LED lub sijhawm. Tsis zoo li cov qij incandescent, LEDs "lifespan" yog txhais raws li tus nqi xav tau thaum lub teeb tso zis txo los ntawm 30%.
Kev siv ntawm LED hauv Teeb pom kev zoo.
LEDs tau muab tso rau hauv qhov muag teeb thiab kev teeb tsa rau kev teeb pom kev dav dav. LEDs yog qhov me me thiab muab kev xaiv tsim tshwj xeeb. Qee qhov kev daws teeb meem LED teeb zoo ib yam li cov teeb pom kev zoo li qub. Qee cov khoom siv LED yuav siv LEDs ua qhov chaw teeb pom kev ruaj khov. Kuj tseem muaj qee lub tshuab hybrid uas siv tsis yog - ib txwm hloov pauv lub teeb los yog "qhov muag teev" tsim tshwj xeeb rau txhua qhov khoom siv. LED muaj ntau lub sijhawm rau kev muaj tswv yim hauv cov teeb pom kev zoo thiab tsim nyog rau ntau yam kev siv ntau dua li cov khoom siv teeb pom kev zoo.
LED thiab Kub.
LED lub dab dej kub absorbs thiab disperses cov cua sov tsim los ntawm LED mus rau ib puag ncig ib puag ncig. Qhov no tiv thaiv LED los ntawm overheating thiab hlawv tawm. Kev tswj cua sov feem ntau yog qhov tseem ceeb tshaj plaws hauv kev lav qhov LED lub sijhawm ua haujlwm ntev -. Qhov kub ntawm LED ua haujlwm ntau dua, lub teeb nrawm dua thiab nws lub neej luv dua. Txhawm rau tswj cov cua sov, LED cov cuab yeej siv ntau yam kev tsim hluav taws xob tshwj xeeb thiab kev teeb tsa. Niaj hnub no, kev nce qib hauv cov khoom siv thev naus laus zis tso cai rau cov tuam txhab tsim cov qij LED uas yog tib daim ntawv thiab loj li cov roj teeb classic. Txawm hais tias lub dab dej kub tsim, tag nrho ENERGY STAR-cov teeb pom kev zoo LED tau raug kuaj xyuas kom paub tseeb tias lawv muaj peev xwm tswj tau cov cua sov kom zoo, ua rau muaj teeb pom kev txaus kom txog thaum lub neej teev tseg.
Dab tsi txawv LED teeb pom kev zoolos ntawm lwm qhov chaw teeb pom kev zoo (cov qij incandescent thiab compact fluorescent teeb)?
LED teeb pom kev sib txawv los ntawm incandescent thiab fluorescent qhov muag teev nyob rau hauv ntau txoj kev. Thaum tsim kom raug, LED teeb pom kev zoo dua, muaj ntau yam kev siv, thiab muaj lub neej ntev dua. LEDs yog "directional" lub teeb qhov chaw, uas txhais tau hais tias lawv tsim lub teeb nyob rau hauv ib qho kev taw qhia. Nyob rau hauv sib piv, incandescent teeb thiab CFL qhov muag teev tso lub teeb thiab cua sov nyob rau hauv tag nrho cov lus qhia. Qhov no txhais tau tias LED teeb pom kev zoo tuaj yeem siv lub teeb thiab lub zog zoo dua hauv ntau yam kev siv. Txawm li cas los xij, kev tsim cov qhov muag teev LED muaj peev xwm ua kom pom lub teeb nyob rau hauv txhua qhov kev taw qhia yuav tsum muaj kev tsim qauv zoo nkauj. Amber, liab, ntsuab, thiab xiav yog cov feem ntau LED hues. Txhawm rau tsim lub teeb dawb, ob peb xim ntawm LEDs yuav tsum tau muab sib xyaw lossis coated nrog cov ntaub ntawv fluorescent hmoov kom tig lub teeb xim rau hauv lub teeb "dawb" nyob rau hauv lub tsev. Fluorescent hmoov yog xim daj daj uas siv rau cov LEDs tshwj xeeb. Xim LEDs feem ntau yog siv los ua teeb liab thiab taw qhia teeb, suav nrog lub zog khawm ntawm cov khoos phis tawj. Cov tam sim no nyob rau hauv compact fluorescent teeb (CFLs) khiav ntawm cov electrodes ntawm txhua qhov kawg ntawm cov pa roj{10}}filled teeb raj. Cov tshuaj tiv thaiv no tsim UV thiab cua sov. Thaum UV hluav taws xob tawm tsam cov fluorescent hmoov txheej hauv lub teeb, nws hloov mus rau qhov pom kev. Kawm paub ntau ntxiv txog CFLs. Incandescent teeb tsim lub teeb los ntawm cua sov cov hlau filament nrog hluav taws xob mus rau lub xeev "dawb" kub (tseem hu ua lub xeev incandescent). Yog li ntawd, qhov muag teev incandescent emit 90% ntawm lawv lub zog raws li cua sov.
