Txawm hais tias qhov tseeb tias cov qij LED dawb yog ib qho kev tsim tshiab tsis ntev los no, lawv tau pom tias lawv yog cov teeb pom kev zoo tshaj plaws uas tam sim no muaj. Hauv daim ntawv no, peb yuav tshawb xyuas qhov laj thawj kev tshawb fawb rau cov teeb ci dawb LED thiab cov yam ntxwv uas lawv ua haujlwm kom txuag tau lub zog.
Txhawm rau pib, cia peb saib sai ntawm cov yam ntxwv uas teeb tsa cov qij dawb LED sib nrug ntawm lwm hom qij. LED teeb qhov muag teev, nyob rau hauv sib piv rau cov pa teeb qhov muag teev, uas tsim lub teeb los ntawm kev siv ib tug filament, emit lub teeb los ntawm kev siv ib tug semiconductor. Thaum cov hluav taws xob tam sim no ntws los ntawm cov khoom siv semiconductor, nws tso tawm lub zog hauv daim ntawv ntawm photons, uas yog cov ntsiab lus tseem ceeb ntawm lub teeb. Lub zog no yog siv los tsim lub teeb.
LED qhov muag teev yuav ua tau los ntawm ntau yam khoom siv semiconductor; Txawm li cas los xij, feem ntau ntawm cov qij LED dawb yog tsim los ntawm kev sib xyaw ntawm xiav lossis violet LED chips nrog cov xim daj phosphor txheej. Tsis tas li ntawd, muaj lwm yam khoom siv semiconductor uas tuaj yeem ua haujlwm. Raws li kev sib xyaw ua ke no, lub teeb lub teeb muaj peev xwm ua kom muaj lub teeb dawb ci ntsa iab.
Yog li, yuav ua li cas raws nraim LED teeb txuag hluav taws xob? Cov tshuaj yuav pom nyob rau hauv lawv cov hauj lwm zoo. Feem ntau ntawm lub hwj chim uas yog siv los ntawm cov tsoos incandescent qhov muag teev yog hloov dua siab tshiab rau hauv tshav kub es tsis yog lub teeb, uas ua rau ib tug tseem ceeb npaum li cas ntawm lub zog raug nkim. Vim li no, lawv tsis muaj txiaj ntsig zoo thiab ua rau muaj kev siv zog ntau heev.
Ntawm qhov tod tes, lub teeb-emitting diode (LED) qhov muag teev yog qhov zoo me ntsis ntawm kev tig lub zog rau hauv lub teeb. Lawv lub zog noj yog nyob nruab nrab ntawm 80 thiab 90 feem pua qis dua li cov teeb pom kev zoo, txawm tias tsim tau tib lub teeb. Qhov no qhia tau hais tias lub teeb incandescent nrog lub zog ib txwm muaj ntawm rau caum watts yuav raug hloov nrog lub teeb ci LED uas tsuas yog rau rau yim watts ntawm hluav taws xob.

Cov teeb pom kev zoo ib txwm muaj lub neej luv luv dua li ntawm LED qhov muag teev, uas yog lwm qhov laj thawj vim li cas LED teeb thiaj li kev lag luam nrog lub zog. Ntawm qhov tod tes, lub teeb ci LED tuaj yeem nyob ntev txog 50,000 teev lossis ntev dua, piv rau lub teeb ci, uas tsuas yog muaj sia nyob ntev li 1,000 teev. Vim li no, koj yuav tsis tas hloov koj lub teeb qhov muag ntau zaus, uas yuav ua rau muaj kev txuag nyiaj ntau nyob rau hauv ob qho tib si kev siv nyiaj thiab kev siv hluav taws xob nyob rau lub sijhawm.
Nws mus yam tsis tau hais tias muaj ntau lub ntsiab lus uas yuav cuam tshuam rau lub zog ntawm LED teeb. Ib qho ntawm lawv yog cov xim kub, uas piav txog lub xim ntawm lub teeb uas yog tsim los ntawm lub teeb. Cov qij sov sov, uas muaj xim kub qis, feem ntau ua haujlwm zoo dua qhov muag teev dawb, uas muaj xim kub dua. Yog li ntawd, cov qij dawb txias yuav ua tau zoo me ntsis.
Ib qho tseem ceeb ntxiv uas yuav tsum tau xav txog yog qhov ci ntsa iab ntawm lub teeb. Lub teeb nrog lub teeb ci ntau dua, feem ntau, muaj lub zog siv ntau dua li lub teeb nrog lub teeb ci qis dua li qub. Ntawm qhov tod tes, qhov no tsis yog ib txwm muaj, txij li qee qhov tsis ntev los no LED qhov muag teev tau tsim los ua kom muaj lub teeb pom kev zoo dua thaum siv lub zog tsawg dua li lawv cov thawj coj.
Dawb lub teeb-emitting diode (LED) qhov muag teev yog lub zog txuag hluav taws xob ntau yam uas yuav pab tau koj txuag nyiaj ntawm koj cov nqi hluav taws xob txhua hli thaum tseem txo koj cov pa roj carbon monoxide. Koj yuav muaj peev xwm ua kom muaj kev kawm paub txog seb cov qij LED puas haum rau koj lub tsev lossis qhov chaw ua lag luam yog tias koj muaj kev nkag siab zoo ntawm kev tshawb fawb uas tom qab lawv ua haujlwm li cas.
