LED xiav lub teeb tawm los, LED kev lag luam tau pib ua rau lub sijhawm tshwm sim
Xyoo 2014 tus neeg yeej khoom plig Nobel hauv Physics Akasaki, Hiroshi Amano thiab Shuji Nakamura tau tsim lub" siab ci ci xiav lub teeb emitting diode&"; xov xwm, uas tau coj txoj hauv kev tshiab rau LED kev lag luam teeb pom kev zoo. Tag nrho cov tuam txhab lag luam LED, cov kws tshaj lij thiab kws tshawb fawb Nws' zoo siab heev.
LED kev lag luam' kev hloov pauv teeb pom kev zoo thib ob, tau pib nyob rau lub sijhawm tshwm sim
Ua ntej tsim lub xiav LED nti, lub teeb dawb tsis tuaj yeem siv tshwj xeeb rau thaj chaw teeb pom kev zoo. Qhov tshwm sim ntawm lub teeb xiav yog tias LED tau nkag mus rau qhov kev thov loj hauv tsev, txoj kev, sab nraum zoov, thiab toj roob hauv pes, thiab tau thim lub sijhawm ntawm cov teeb roj teeb thiab teeb lub zog txuag hluav taws xob. Lub ntiaj teb tau txo qis carbon emissions, txuag lub zog, thiab muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig.
Peb tus kws tshawb fawb no tau siv cov khoom siv hluav taws xob kom tau txais lub teeb ci xiav thaum ntxov xyoo 1990, uas tau hloov pauv qhov tseem ceeb hauv kev txhim kho thaj chaw teeb pom kev zoo. Xiav LED paub tias yog kev hloov pauv teeb pom kev thib ob tom qab Edison.
Nrog kev nrawm ntawm kev tshem tawm cov teeb roj teeb thiab qhov kawg ntawm txoj cai nyiaj pab rau teeb roj teeb txuag hluav taws xob, cov khoom siv teeb pom kev zoo LED tau maj mam nrov thiab hloov tag nrho cov khoom lag luam teeb pom kev zoo. Thiab nws yog qhov kev txhim kho keeb kwm yav dhau los uas ua rau muaj kev cuam tshuam ntawm LEDs rau tib neeg lub neej tob dua, thiab lub luag haujlwm ntawm LEDs rau tib neeg tau nce zuj zus thoob ntiaj teb.
Tuam Tshoj' s LED kev lag luam nyob rau thawj hauv ntiaj teb, thiab kev sib tw hauv tuam txhab nce ntxiv thiab cov nyiaj tau los qis qis qis
Txawm hais tias qhov no, hauv Suav teb' lub sijhawm luv luv ntawm tsawg dua kaum xyoo, kev lag luam LED hauv tsev tau nyob deb ua ntej hauv ntiaj teb raws li kev ntsuas, daim ntawv thov kev hloov pauv tshiab thiab kev tswj kom zoo, thiab khov kho thawj qhov chaw .
Txij li xyoo 2013, kev hloov pauv LED hauv ib puag ncig ntawm cov khoom siv teeb pom kev zoo tau nrawm dua, thiab kev lag luam teeb pom kev zoo tau nkag mus rau ib puag ncig tshiab ntawm kev txhim kho kev lag luam. Tam sim no, muaj ntau lub tuam txhab lag luam hauv kev lag luam teeb pom kev zoo hauv tsev LED thiab kev sib tw yog tsiv heev. Kev nthuav tawm cov peev txheej tsim khoom thiab homogenization ntawm cov khoom tau ua rau muaj kev tsov rog, thiab cov nyiaj tau los tag nrho ntawm cov khoom tau maj mam poob qis.
Yav tom ntej LED kev lag luam, teeb pom kev zoo tsuas yog suav txog 10% -20% ntawm kev ua haujlwm. Ntau lub zog muaj zog tuaj yeem dag hauv nws qhov kev txawj ntse, Internet thiab ntau lwm yam haujlwm. Kev koom ua ke ntawm ntau daim ntawv thov thev naus laus zis yog yav tom ntej ntawm LED teeb pom kev zoo. Qhov ntxim nyiam dag.
