Lub teeb -emitting diode (LED) qhov muag teev: yuav ua li cas lawv txo cov nqi kho, ua kom ci, thiab ua rau lwm yam
Muaj qee qhov kev tawg uas tau muaj qhov tseem ceeb ntawm kev cuam tshuam ntawm kev lag luam teeb pom kev zoo raws li lub teeb -emitting diode (LED) qhov muag teev muaj nyob rau hauv lub tsev thiab lub lag luam teeb pom kev zoo. Cov qij taws, uas nkim ntau lub zog raws li qhov kub thiab txias, thiab cov raj fluorescent, uas muaj cov tshuaj lom neeg thiab tso cai txwv tsis pub tswj cov teeb pom kev zoo, yog hom teeb pom kev zoo tshaj plaws siv hauv tsev thiab chaw ua haujlwm rau ntau xyoo lawm. Niaj hnub no, lub teeb -emitting diode (LED) qhov muag teev tau dhau los ua tus qauv kev lag luam, ua rau muaj kev hloov pauv hauv kev teeb pom kev zoo ua tsaug rau peb qhov tseem ceeb: kev lag luam hluav taws xob, uas txo cov nyiaj siv rau cov nqi hluav taws xob; brightness ntau dua, uas enriches qhov chaw; thiab zoo heev durability, uas outlass tag nrho cov tsoos kev xaiv.
Nws yog ib qho tseem ceeb rau kev kawmefficiency ntawm LEDsHauv kev sib piv rau cov thev naus laus zis dhau los txhawm rau nkag siab tias vim li cas LEDs yog qhov kev ua si - hloov pauv ntawm kev txuag hluav taws xob. Thaum lub sij hawm ua hauj lwm ntawm incandescent qhov muag teev, ib tug tungsten filament yog rhuab kom txog thaum nws glows. Cov txheej txheem no ua rau poob txog li 90 feem pua ntawm lub zog uas siv los ua cua sov ntau dua li lub teeb. Thaum siv 60 watts ntawm hluav taws xob, lub teeb pom kev zoo ib txwm muaj lub zog hluav taws xob ntawm 60 watts tsim ib puag ncig 800 lumens, uas yog chav ntsuas rau qhov ci. Lub teeb -emitting diode (LED) qhov muag, ntawm qhov tod tes, tuaj yeem siv tsuas yog 8-10 watts los muab tib 800 lumens. Qhov no ua rau muaj kev txuag hluav taws xob uas nyob ib puag ncig 85 feem pua. Lub Tebchaws Asmeskas Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob kwv yees tias kev siv dav dav ntawm lub teeb -emitting diodes (LEDs) tuaj yeem txiav lub teb chaws siv hluav taws xob rau kev siv teeb pom kev zoo li tsib caug feem pua los ntawm xyoo 2030, uas ua rau cov nyiaj txuag txhua xyoo ntawm billions nyiaj.
Kev siv teeb pom kev zoo tuaj yeem raug txo los ntawm $ 75 ib xyoos ib zaug rau lub tsev ib txwm siv los ntawm kev hloov tawm tsuas yog kaum lub qhov muag teev nrog lub teeb ci -emitting diode (LED) qhov muag teev. Cov nyiaj khaws cia uas tshwm sim los ntawm qhov no ntxiv txog ntau pua nyiaj thaum lub neej ntawm LEDs; qhov no yog cov nyiaj uas khaws cia hauv hnab ris ntau dua li them rau cov tuam txhab hluav taws xob. Tshaj li lawv lub peev xwm txuag nyiaj, lub teeb -emitting diodes (LEDs) ua tau zoo tshaj plaws hauv kev muab lub teeb ci siab dua thiab lub teeb zoo. Lub ci ntsa iab uas yog tsim los ntawm cov khoom siv hluav taws xob yog qhov sov, tab sis feem ntau tsis sib xws, thiab lawv muaj peev xwm ua rau muaj kev cuam tshuam ntau yam. Cov qhov muag teev cov teeb pom kev zoo muaj zog ntau dua li cov qhov muag teeb fluorescent; Txawm li cas los xij, lub teeb fluorescent feem ntau ua rau lub teeb hnyav, txias uas tuaj yeem ua rau qhov muag tsis pom kev thiab cov xim tsis zoo. Ntawm qhov tod tes, LEDs muab kev tswj xyuas meej ntawm qhov ci thiab xim kub, uas ntsuas hauv Kelvins (K). Dawb LEDs nrog qhov ntsuas kub ntawm 2700K txog 3000K muab lub teeb sov, daj daj uas haum rau chav nyob thiab chav pw. Ntawm qhov tod tes, cov LEDs txias txias nrog qhov kub ntawm 5000K txog 6500K tsim lub teeb ci, nruab hnub nrig-zoo li teeb pom kev zoo rau chav ua noj, chaw ua haujlwm, thiab chaw ua haujlwm.
Tsis tas li ntawd, LEDs muaj lub siab xim Rendering Index (CRI), uas yog qhov ntsuas uas txiav txim siab seb lub teeb pom kev zoo li cas qhia cov xim piv rau lwm qhov chaw ntawm lub teeb, xws li lub teeb ntuj. Feem ntau ntawm cov LEDs muaj xim rendering Performance index (CRI) ntawm 80 los yog ntau tshaj, nrog hwm versions mus txog 90 los yog siab dua. Qhov no ua kom cov rooj tog zaum, kos duab, thiab txawm tias cov tawv nqaij zoo li ci ntsa iab thiab muaj tseeb rau lub neej, uas yog ib yam dab tsi uas tsis muaj zog (CRI 100 tab sis tsis muaj txiaj ntsig) thiab fluorescents (CRI 60-70) tawm tsam kom ua tiav. LEDs ua tiav cov teeb pom kev zoo nyob rau hauv cov nqe lus ntawm durability, uas yog lwm qhov chaw uas lawv ua tau zoo. Muaj tsuas yog ib txhiab teev lifespan rau qhov muag teev, uas txhais tau hais tias yog lawv siv peb teev txhua hnub, lawv yuav hlawv tawm hauv tsawg dua ib xyoos. Compact fluorescent teeb (CFLs) muaj lub neej ntev, nyob ib ncig ntawm 8,000 txog 10,000 teev; Txawm li cas los xij, lawv suav nrog mercury, ib qho chaw txaus ntshai uas yuav tsum tau muab pov tseg hauv qee yam. Ntawm qhov tod tes, LEDs muaj lub neej ntev ntawm 25,000 thiab 50,000 teev.
Qhov nruab nrab LED teebyuav kav li ntawm 23 mus rau 46 xyoo yog tias siv peb teev txhua hnub, uas txhais tau hais tias ntau tsev neeg yuav tsis tau hloov lub teeb LED uas lawv nruab hnub no. Qhov kev ruaj khov no yog los ntawm cov khoom siv - lub xeev kev tsim kho ntawm LEDs, uas tshem tawm qhov xav tau ntawm cov filaments lossis iav raj kom tawg. Raws li qhov tshwm sim, LEDs tiv taus kev ntxhov siab, kev co, thiab kub hloov pauv. Tsis tas li ntawd, lawv khiav ntawm qhov kub thiab txias uas qis dua li cov incandescents, uas txo qhov muaj peev xwm ntawm hluav taws kub nyhiab nrog rau kev puas tsuaj rau cov khoom siv lossis cov khoom siv uas nyob ib puag ncig. Hauv kev lag luam ib puag ncig xws li chaw ua haujlwm, tsev khaws khoom, lossis teeb pom kev, qhov chaw hloov cov qij yog ob qho tib si kim thiab siv zog- siv zog, LEDs txo cov nyiaj tau los ntawm kev saib xyuas thiab lub sij hawm poob vim kev poob qis. Nws yog yav tas los ntseeg tias LEDs tau kim heev, nrog cov nqi pib uas ntau dua li cov incandescents lossis compact fluorescent teeb (CFLs). Ntawm qhov tod tes, cov nqi tau nqis los ntawm ntau dua 80 feem pua ntawm cov xyoo dhau los, ua rau lawv pheej yig rau feem ntau ntawm tsev neeg. Lub teeb-emitting diodes (LEDs) sai sai them rau lawv tus kheej thaum ib tus xav txog kev txuag hluav taws xob thiab txo cov nqi hloov pauv. Ib lub teeb ci LED uas siv 10 watts, tsis zoo li lub teeb ci uas siv 60 watts, yuav txuag tau li ntawm rau las ib xyoos hauv hluav taws xob (raws li kaum xees ib kilowatt- teev).
Thaum lub sij hawm nws lub neej ntawm 25,000 teev, qhov no sawv cev rau kev txuag ntawm 150, uas deb tshaj qhov pib tus nqi sib txawv. Tsis tas li ntawd, tsoomfwv thiab cov khoom siv hluav taws xob qee zaum muab cov nyiaj rov qab lossis kev txhawb siab rau kev hloov mus rau LEDs, uas txo qhov cuam tshuam rau kev siv cov thev naus laus zis no. LEDs yeej ib txwm tau zoo dua li cov thev naus laus zis txuas ntxiv mus. LEDs niaj hnub no tuaj nyob rau hauv ntau hom, nrog rau lwm yam dimmable, ntse qhov muag teev uas muaj peev xwm txuas mus rau lub tsev automation systems, thiab txawm xim - hloov cov uas yuav hloov nyob rau hauv teb rau suab paj nruag los yog mus ob peb vas. LEDs yog qhov tseeb los ua lub teeb pom kev zoo ntawm lub neej yav tom ntej vim qhov kev nce qib no, ntxiv rau nws cov txiaj ntsig tseem ceeb ntawm kev ua tau zoo, ci ntsa iab, thiab lub neej ntev. LED qhov muag teev tsis yog ib qho kev xaiv teeb pom kev zoo xwb; lawv kuj yog ib qho kev nqis peev uas tsim nyog rau kev txuag nqi, kev nplij siab, thiab lub luag haujlwm ntawm ib puag ncig. Qhov no muaj tseeb txawm tias lawv siv hauv tsev, tuam txhab, lossis chaw pej xeem.LED qhov muag teevyog superior rau ib txwm teeb pom kev zoo nyob rau hauv ib tug xov tooj ntawm txoj kev, nrog rau lawv lub peev xwm los txo cov kev siv hluav taws xob los ntawm 85 feem pua, lawv lub peev xwm los txhim kho ib puag ncig nrog adjustable brightness thiab zoo heev xim raug, thiab lawv muaj peev xwm nyob nruab nrab ntawm 25 thiab 50 lub sij hawm ntev tshaj li incandescent teeb. LEDs yog qhov kev xaiv teeb pom kev zoo tshaj plaws txij li lawv muab sijhawm ntev - txuag nyiaj thiab kev ruaj khov thaum ua ke nrog qhov tseeb tias lawv cov nqi txo qis thiab lawv muaj cov yam ntxwv ntxiv xws li kev tswj hwm ntse.
