Tom qab xyoo ntawm txoj kev loj hlob, Tuam Tshoj txoj kev lag luam LED saw tau ua tiav tiav.Txawm li cas los xij, Wang Ying, tus kws tshuaj ntsuam xyuas ntawm CCID Consulting's Semiconductor Industry Research Center, tau hais rau cov neeg sau xov xwm ob peb hnub dhau los tias saib LED kev lag luam saw, vim tias cov thev naus laus zis siab thiab peev txheej ntawm kev lag luam nce siab, ob peb lub tuam txhab hauv tsev tau koom nrog.Yog li ntawd, muaj ob peb lub tuam txhab nyob rau hauv lub upstream kev lag luam.Cov yam ntxwv ntawm cov nplai me me.Nyob rau hauv sib piv, downstream ntim thiab daim ntawv sau npe muaj kuj tsis tshua muaj peev thiab cov kev cai rau cov tuam txhab uas muag, uas phim cov yam ntxwv ntawm domestic tuam txhab uas muag 'tsawg peev thiab tsis muaj zog technology.Yog li ntawd, tus naj npawb ntawm domestic tuam txhab uas muag koom nyob rau hauv ntim thiab daim ntaub ntawv yog kuj loj.Qhov xwm txheej no tau ua rau muaj qhov tseeb tias kev lag luam LED hauv tsev feem ntau yog cov khoom lag luam qis, thiab cov tuam txhab tau ntsib tus nqi hnyav rau lub sijhawm ntev.

Raws li tus neeg sau xov xwm nkag siab, tam sim no, nrog rau kev pib ntawm National Semiconductor Lighting Project, cov xwm txheej ntawm LED kev lag luam hloov pauv.LED kev lag luam upstream tau tsim sai heev, thiab kev loj hlob ntawm kev lag luam nti yog qhov muag pom tshaj plaws.Tab sis los ntawm qhov kev xav ntawm kev lag luam nplai, ntim khoom tseem yog qhov kev lag luam loj tshaj plaws hauv kev lag luam LED.Nyob rau hauv 2016, tag nrho cov zis tus nqi ntawm kuv lub teb chaws LED kev lag luam mus txog 10.55 billion yuan, uas cov zis tus nqi ntawm lub ntim kev lag luam mus txog 8.75 billion yuan.Wang Ying tau soj ntsuam tias qhov kev xav tau ntawm kev lag luam thoob plaws ib puag ncig thiab tsoomfwv txoj kev txhawb nqa muaj zog yog qhov muaj txiaj ntsig zoo los xyuas kom muaj kev loj hlob ntawm LED kev lag luam.Nyob rau hauv xyoo tas los no, LED daim ntawv thov kev lag luam xws li cov ntxaij vab tshaus, teeb pom kev zoo toj roob hauv pes, teeb pom kev tsheb, kev siv tsheb, thiab teeb pom kev zoo tau tshwm sim sai.Kev txhim kho tas mus li ntawm LED luminous efficiency yuav tsum tau nyob rau hauv daim ntawv thov kev lag luam tawm tshiab tau nthuav tawm qhov kev thov rau cov khoom nruab nrab mus rau high-end.Nrog rau kev nce hauv kev lag luam kev xav tau, kev txhim kho ntawm LED nti kev lag luam cov khoom lag luam maj mam nrawm dua, thiab cov khoom siv chip LED yuav txav mus rau qib siab tag nrho.Ntawm qhov tod tes, txoj kev loj hlob sai ntawm LED ntim kev lag luam kuj muab kev lag luam dav dav rau LED chips, uas nyob rau hauv lem muab ib tug zoo sab nraud ib puag ncig rau txoj kev loj hlob ntawm LED kev lag luam.

Lub xeev kuj tau muab kev txhawb zog rau txoj kev loj hlob ntawm LED kev lag luam.Nyob rau hauv 2016, raws li txoj cai txoj kev loj hlob ntawm kuv lub teb chaws lub semiconductor teeb pom kev lag luam, cov koom haum tsim cov semiconductor teeb pom kev lag luam txoj kev loj hlob txoj kev npaj thiab cov txheej txheem txoj kev loj hlob technology rau xyoo 2016 tau hais tias kev nqis peev hauv LED chips yuav suav txog 20% ​​ntawm LED kev lag luam peev, thiab kev tshawb fawb tsom mus rau GAN chips.Kev tsim khoom thiab lub zog nti kev tshawb fawb thiab kev tsim kho.

Txawm hais tias muaj kev lag luam xav tau zoo thiab muaj kev txhawb nqa los ntawm cov koom haum cuam tshuam, nws yog qhov tsis lees paub tias LED nti kev lag luam tseem muaj teeb meem kev txhim kho xws li tsis muaj cov thev naus laus zis thev naus laus zis, tsis muaj cov txuj ci tshaj lij, cov khoom lag luam tsis zoo, thiab cov cuab yeej tsis muaj zog muaj peev xwm tsim tau.Yuav ua li cas daws cov teeb meem saum toj no yog tus yuam sij rau kev noj qab haus huv, kev noj qab haus huv thiab kev loj hlob sai ntawm kuv lub teb chaws LED kev lag luam.

Wang Ying ntseeg hais tias txoj kev loj hlob sai ntawm LED nti kev lag luam yuav txhawb nqa tag nrho kev txhim kho ntawm LED kev lag luam.Nyob rau hauv txoj kev loj hlob ntawm LED nti kev lag luam, cov khoom thaum ntxov yog cov zoo tib yam brightness chips, thiab tsuas muaj ob peb manufacturers xws li Nanchang Xinlei.Tom qab xyoo 2013, chip manufacturers sawv cev los ntawm Xiamen San'an thiab Dalian Lumei tau tsom lawv cov khoom ntawm high-brightness chips teb rau cov kev xav tau ntawm kev ua lag luam nti, ncaj qha tsav kev loj hlob sai ntawm high-brightness nti ntau lawm.Rau ib lub sij hawm, lub domestic LED nti kev lag luam tau teem tawm ib tug upsurge ntawm txoj kev loj hlob, thiab high-brightness chips tau dhau los ua lub ntsiab tsav tsheb rau txoj kev loj hlob ntawm LED nti kev lag luam.Nyob rau hauv 2016, cov zis ntawm LED chips nyob rau hauv kuv lub teb chaws mus txog 30.93 billion, thiab cov zis tus nqi mus txog 1.19 billion yuan.

Nrog rau kev nce ntxiv ntawm LED nti tsim cov tuam txhab, qhov kev loj hlob ntawm LED nti tso zis tus nqi tau siab dua li ntawm cov khoom sib txuas, uas ua rau muaj kev nce ntxiv ntawm cov nti tso tawm tus nqi hauv cov khoom tsim tawm ntawm kuv lub teb chaws LED kev lag luam, los ntawm 5.4% hauv 2012 txog 2016. 11.3%.Nws tuaj yeem pom tau tias kuv lub teb chaws LED kev lag luam tau txav los ntawm qis-kawg mus rau high-end, thiab tab tom mus rau ntau dua tus nqi-ntxiv thiab ntau qhov tseem ceeb-nqi chip txuas.
