Puas yog LEDs siv sijhawm ntev txog 50000 teev?
LEDs tau dhau los ua neeg nyiam ntau xyoo, nrog ntau tus neeg hloov los ntawm cov teeb pom kev zoo ib txwm siv rau LED teeb pom kev zoo hauv lawv lub tsev thiab kev lag luam. Ib qho ntawm cov ntsiab lus muag ntawm LED qhov muag teev yog lawv lub neej zoo, nrog ntau lub tuam txhab thov tias lawv cov qij tuaj yeem kav ntev txog 50000 teev lossis ntau dua. Tab sis qhov kev thov no puas muaj tseeb?
Ua ntej, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub neej ntawm LED teeb tuaj yeem sib txawv nyob ntawm ntau yam, suav nrog qhov zoo ntawm lub teeb, kev ua haujlwm, thiab cov qauv siv. Piv txwv li, ib lub teeb LED uas siv rau ob peb teev txhua hnub hauv qhov chaw sov tuaj yeem muaj lub neej luv dua li ib qho uas tsuas yog siv qee zaus hauv qhov chaw txias dua.
Txawm hais tias cov kev hloov pauv no, muaj pov thawj los qhia tias LEDs yeej tuaj yeem kav ntev li 50000 teev lossis ntau dua. Qhov tseeb, ib txoj kev tshawb fawb los ntawm US Department of Energy tau pom tias ntau qhov zoo ntawm LED qhov muag teev muaj peev xwm tuav tau tsawg kawg yog 70% ntawm lawv cov teeb pom kev zoo rau ntau tshaj 25000 teev ntawm kev siv. Qhov no txhais tau hais tias txawm tias tom qab 25000 teev, cov qij tseem ua haujlwm ntawm kev ua haujlwm siab dua piv rau lawv cov txiaj ntsig thawj zaug.
Txawm li cas los xij, tsis yog txhua qhov LED teeb tau tsim sib npaug, thiab qee qhov yuav muaj lub neej luv dua li lwm tus. Nws yog ib qho tseem ceeb uas yuav tau xaiv cov chaw tsim khoom muaj npe nrov thiab xyuas cov khoom tshwj xeeb ntawm lub teeb ua ntej yuav khoom. Tsis tas li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau siv lub teeb nyob rau hauv qhov tsim nyog thiab ua raws li cov lus pom zoo lossis cov lus qhia los ntawm cov chaw tsim khoom txhawm rau ua kom nws lub neej ntev tshaj plaws.
Hauv cov ntsiab lus, thaum lub neej ntawm LED teeb tuaj yeem sib txawv nyob ntawm ntau yam, muaj pov thawj los qhia tias lawv tuaj yeem kav ntev li 50000 teev lossis ntau dua. Los ntawm kev xaiv lub teeb pom kev zoo thiab siv nws kom tsim nyog, koj tuaj yeem pab xyuas kom koj lub teeb pom kev zoo LED muab ntau xyoo txhim khu kev qha thiab ua haujlwm tau zoo.
