LED tsav tsheb thev naus laus zis rau kev hloov pauv mus sij hawm ntev
txhawm rau lav kom muaj qhov ci ntsa iab rau LED teeb pom kev zoo nrog lub sijhawm tsim khoom lag luam ntev, muaj LEDs nrog qhov ci ci tas li nyob rau hauv cov khoom lag luam isoften tseem xav tau lossis xav tau. qhov teeb meem tuaj yeem zam lossis tshem tawm tag nrog kev daws yooj yim.
A. Taw qhia
Hauv kaum xyoo dhau los, cov teeb pom kev ntawm LED tau dhau los ntawm kev txhim kho yam tsis tau xav txog thiab tau nthuav dav ntau zaus raws li kev hloov pauv rau lub teeb ci. Qhov laj thawj tseem ceeb rau lawv nkag mus rau txhua ntu ntawm qhov pom kev yog qhov nce ntxiv hauv cov khoom siv hluav taws xob thiab ua kom pom kev ua haujlwm dhau sijhawm. Qhov no tseem yog qhov tseem ceeb hauv LED lub peev xwm los daws cov teeb meem ntawm kev teeb pom kev zoo. Thaum xub thawj siab ib muag, qhov nce ntxiv ntawm cov teeb pom kev zoo li muaj teeb meem rau cov kab ke nrog cov khoom lag luam ntev, uas zoo ib yam, cov yam ntxwv zoo ib yam thiab tus cwj pwm xav tau ntau dua cov khoom lag luam lub neej. Yog tias qhov kev nce qib lossis hloov pauv twb tau txiav txim siab hauv tus qauv tsim, txawm li cas los xij, cov teebmeem tuaj yeem yooj yim them rau hauv kev sib txuas nrog kev pab los ntawm PWM tus tsav tsheb. cov khoom lag luam thiab lawv cov yam ntxwv tuaj yeem lees paub yam tsis tas yuav siv LEDs nrog qhov zoo ib yam qhov ci.
B. Hauv paus
Ua kom lub teeb ci ci Lub hom phiaj xav tau ntawm LED cov tuam txhab hloov khoom siv teeb pom kev zoo nrog LEDs ua rau muaj kev sib tw hnyav nrog kev hwm rau kev txhim kho thiab kev tsim tawm ntau ntawm cov teeb pom kev zoo dua qub, tshwj xeeb yog LEDs dawb. Thaum kawg, qhov no tseem ntxiv qhov txiav txim siab tseem ceeb ntawm cov txheej txheem txhim kho ntawm LEDtechnology ob peb xyoos dhau los. Txog LEDs, qhov kev xav dav dav yog tias qhov kev txhim kho no tseem tsis tau mus txog. Saib rov qab, nws tuaj yeem txiav txim siab tias nyob nruab nrab ntawm 1960 thiab 2000, qhov hluav taws xob tau teeb ntawm LEDs tau ze li ob npaug txhua ob xyoos. Kev cia siab tias yuav nce ntxiv yav tom ntej tuaj yeem ua piv txwv yog tias ib qho ua raws li kev kwv yees kev ua tau zoo ntawm Asmeskas Lub Tsev Haujlwm Saib Xyuas Kev Ua Haujlwm los ntawm 2017, piv txwv li (Daim duab 1). Raws li kev lag luam thiab chaw kuaj mob txij li xyoo 2005 txog rau hnub no nws qhia pom qhov ua tau zoo ntawm cov LEDs dawb rau xyoo tom ntej nrog qhov siab tshaj plaws txwv txog 250 lm/W. Thov mus ntsib USDepartment of Energy thiab daim ntawv tshaj tawm “Solid-State Lighting 2017 SuggestedReasearch Topics [1]” kom paub ntxaws ntxiv.
Kev cuam tshuam ntawm kev faib khoom tsim tawm thiab qhov muaj ntawm cov thoob LED
Los ntawm lub hauv paus txheej mus rau kev teeb tsa lub semiconductor nti hauv tsev, LED kev tsim khoom cuam tshuam nrog ntau cov txheej txheem txheej txheem thiab cov txheej txheem nyuaj (Daim duab 2). theej, qhov ntsuas poob nrog qee qhov txwv txwv nthuav tawm kev faib khoom (Daim duab 3). Raws li qhov tshwm sim ntawm no, txhua tus LED yog tus yam ntxwv thiab muab tso rau hauv lub npe hu rau hauv, nrog cov lus qhia tshwj xeeb hais txog xim, ci ci thiab rau pem hauv ntej qhov hluav taws xob. Ua li no, kev faib khoom faib tawm tau cais ua ob peb lub thoob sib txawv, qee zaum kev daws teeb meem hauv ntau dua ib puas qhov sib xyaw ua ke. Txog kev tsim khoom faib tawm, qhov no txhais tau tias thaum kawg, kev ntsuas tus kheej rau kev nce qhov ci ci ua rau hloov mus rau qhov pom kev zoo dua.
Qhov kev tsom mus rau kev txhim kho no ib txwm cuam tshuam nrog kev hloov pauv hauv kev muaj nuj nqis ntsig txog kev faib cov LEDs hauv lub thoob, txawm li cas los xij. Txog qhov muaj ntawm ib tus neeg hauv lub thoob, qhov no txhais tau tias nyob ntawm tus nqi ntawm qhov ci ci ntxiv, LEDs nrog tus nqi ci tshwj xeeb yuav tsuas yog tshwm sim hauv qhov txo qis lossis tej zaum tsis yog txhua lub sijhawm tsim khoom. Cov thoob uas yav dhau los tau sawv cev hauv qhov ntau nyob hauv nruab nrab ntawm kev tsim khoom tom qab ntawd yuav raug hloov mus rau ntug ntawm qhov kev faib khoom tshiab nrog qis dua LED feem pua, lossis yuav tsis nyob tam sim no. Qhov no txuas ntxiv mus ua kom zoo dua qub thiab txhim kho ntawm LED thev naus laus zis muaj feem cuam tshuam rau kev siv LED ntawm cov neeg siv khoom, txawm li cas los xij. Kev hloov kho ntawm cov khoom lossis lawv cov khoom ib txwm ua rau hloov pauv ntawm cov yam ntxwv ntawm lub system yog tias lawv tsis raug txiav txim siab. Qhov no tshwj xeeb tshaj yog rau kev siv nrog cov khoom lag luam ntev, zoo ib yam hauv khw muag khoom tsheb, piv txwv. Ntawm no, cov ntawv thov siv sijhawm ntev yam tsis muaj kev hloov pauv thiab tseem yuav tsum muaj nyob rau lub sijhawm sib xws. Cov khoom lag luam nrog nws cov theem sib txawv tuaj yeem kav ntev dua kaum xyoo hauv qhov no. Qhov tsis sib xws ntawm cov txheej txheem ntawm LED hloov pauv thiab cov khoom siv lub neej ntawm daim ntawv thov tuaj yeem ua rau muaj teeb meem sib xws.
