Yuav Ua Li Cas Rau Lub Lag Luam Teeb Lag Luam Hauv 2019
Raws li cov kev soj ntsuam ntawm LED hauv, xyoo 2018, qhov kev lag luam hauv BP tau cuam tshuam los ntawm cov neeg txom nyem qhov kev xav tau, ua ke nrog cov kev cuam tshuam ntawm Tuam Tshoj thiab Teb Chaws Asmeskas txoj kev lag luam, uas coj mus rau qhov yuav txo tau ntawm cov lus nug theem ntawm cov neeg, pom ib lub ntse khov ntse.
Nrhiav rau pem hauv ntej kom 2019, Txawm hais tias tag nrho kev lag luam tseem muaj qhov kev pheej hmoo ntawm oversupply, tshwj xeeb daim ntawv nrauj nrog me kev sib tw LED zaub, Mini LED backlight, UV-C LED, automotive teeb pom kev zoo thiab high-efficiency teeb pom kev zoo uas muaj kev cia siab rau tsav cov lus thov ua kom sov.
LED hauv kev taw qhia tias kev lag luam ntawm Suav thiab Teb Chaws Asmeskas tom qab lub G20 ceasefire ib ntus, thiab cov tariffs uas yuav tsum tau pib thaum Lub Ib Hlis 1, 2019 yuav ncua sij hawm rau peb lub hlis. Kev lag luam ntawm LED, nws yuav ntsib 25% los yog 10% tariff qhov txawv yav tom ntej, uas yuav hloov txoj kev npaj yuav khoom thiab kev txav tawm ntawm cov tuam txhab, thiab tom qab ntawd tseem tsis tau meej meej ntawm Tuam Tshoj thiab Tebchaws Meskas, uas yuav ncua qhov tseem kev txiav txim siab ua lub sij hawm, kev lag luam tos-thiab-saib cua thiab qhov tsis muaj tseeb ntawm kev ua lag luam, thiab ntshai tsam kev txhawb nqa kev ua haujlwm ntawm kev xav tau sab.
Me Spacing LED Zaub Screen
Nrog rau qhov kev lag luam ntawm kev lag luam hauv khw, khw muag khoom khw muag khoom, rooj sib tham chav thiab lwm yam kev lag luam, qhov tso tawm tus nqi ntawm qhov kev sib tw me me coj mus rau 31% ib xyoos ib zaug hauv xyoo 2018. Raws li kev soj ntsuam ntawm LED, , qhov nyiaj ntawm LED zaub npo yog txiav txim siab, thiab qhov kis tau nrawm miniaturization tseem tuaj yeem coj dua tshiab daim ntawv thov scenarios.
Tsis tas li ntawd, tus nqi ntawm LED chips tau poob, ua rau tus nqi siv hluav taws xob muaj txiaj ntsig ntawm LED cov duab hauv kev lag luam siv tshaj lwm cov kev siv yees, yog li muaj ntau yam LCD vajtse manufacturers thiab coj mus muag zaub hom tuam txhab xav ua kom muaj kev sib tw me me.
Raws li LED sab hauv, tuam txhab uas muag tau txais kev lag luam hauv cov khoom me me ntawm cov khoom siv me me, xws li Jingdian, Sanan, Huacan, Yiguang, Guoxing, Hongqi thiab Jingtai, li yuav txhawb cov IC manufacturers xws li cov khoom siv hluav taws xob thiab tsim lub North.
Mini LED Backlight
Mini LED yog siv hauv LCD. Nrog cov cuab yeej ntawm kev cia siab hauv cheeb tsam nram qab teeb, nws tuaj yeem ua qhov sib txawv thiab ci ci ntawm LCD, thiab muab kev pab nrog lwm qhov kev xaiv dua li ntawm OLED. Kev siv Mini LED backlight 27 nti duab ua piv txwv li, qhov siv LED siv yog kwv yees li ntawm 4,000-12,000, thiab siv ntau qhov chaw nta kev tswj yus tus kheej yuav pab txhim kho qhov sib txawv thiab coj cov tub ntxhais kawm zoo dua tuaj pom.
Txawm li cas los xij, nyob rau theem no, vim yog tus nqi siab ntawm kev siv tshuab, nws tsuas yog siv cov qauv ua qauv siab. Nyob rau hauv lub neej yav tom ntej, yog hais tias tus nqi ntawm Mini LED thiab cov cuab yeej ntawm huab hwm coj hloov ua tau kov kev loj hlob, Mini LED backlight technology yuav tsum tau siv ntau nyob rau hauv ntau cov lus qhia, uas yuav ua tau zoo txhawb cov nti ntawm LED kev lag luam.
Nws xav pom tias ntev ntev hauv kev tshav pob ntawm kev lag luam, los yog cov chaw lag luam nrog cov khoom siv tom qab, xws li Crystal Electric, Lunda, Guangyong, Rongchuang, Ruifeng, thiab lwm yam, yuav coj cov hlau lead hauv kev xav txog Mini LED kev lag luam.
UV-C LED
Daim ntawv thov kev lag luam ntawm UV-C LED nrog rau peb lub zog loj hlob: qhov dej qub sterilization, deg sterilization thiab mobile sterilization.
Tsis txhob siv sij hawm ntau dua, tab sis vim cov ntawv thov no tau xa mus rau cov khoom siv hauv tsev neeg, qhov uas yuav tsum tau ua rau cov khoom ua tau zoo tshaj plaws yog qhov siab, ua rau cov UV-C LED tsis tuaj yeem siv rau lub sijhawm luv luv.
Raws li rau daim ntawv thov ntawm cov dej txauv txawb dej, nws xav tau kev ceev sterilization, thiab yuav tsum muaj siab zog ntawm cov khoom, li ntawd, lub zog ntawm UV-C LED yuav tsum siab tshaj 40-50 mW.
Raws li LED sab hauv, qhov teeb meem loj tshaj plaws rau UV-C LEDs nyob rau theem no tseem yog qhov technology thiab kev ua kom tau zoo tuaj, tab sis cov kev teeb meem no yuav muaj sijhawm rau yav tom ntej. Txawm li cas los, UV-C LED belongs rau lub khw muag khoom niche, thiab kev siv tshuab yuav tsum tau tsim kom ntev, thiaj li tsuas muaj ob peb tuam txhab xws li Seoul Semiconductor, LG Innotek, Qingdao Jiesheng, Guangyong, RG, Guangbao, Yiguang, Violumas thiab yog li yuav tau txais txiaj ntsig.
Automotive LED
Nrog txo tus nqi ntawm LED thiab nce ntawm nws cov kev ua haujlwm, tus nqi tso zis thiab nkag mus ntawm tsheb LED teeb pom kev zoo txuas mus ntxiv, thiab qhov tso tawm tus nqi ntawm lub tsheb LED hauv xyoo 2018 tau mus txog 15% txhua xyoo. Ntawm lawv, qhov kev thov rau taub hau thiab lub tsheb panels yog nce ceev ceev.
Txawm li cas los xij, vim muaj kev kub siab rau cov tuam txhab LED hauv kev lag luam automotive pem hauv ntej thiab cov neeg ua lag luam uas xav ua kom muaj kev sib txuas ua ke nrog lub teeb nrawm, cov tsheb thauj khoom hauv kev muag tsheb tseem tseem muaj feem los ntawm ntau cov lag luam xws li Osram , Nissan Tshuaj, Lumileds thiab lwm yam. Tus LD tuam txhab ntawm cov khw muag khoom loj dua los ntawm kev lag luam thiab kev lag luam, los yog rau sab nrauv teeb, taillights thiab lwm qhov chaw tsawg thiab kev nkag siab ntawm cov kev siv LED.
Cov teeb pom kev zoo siab Highlight LED teeb
Vim yog cov kev cai tswjfwm nce rau kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig hauv ntau lub teb chaws, LED teeb pom kev zoo tuaj yeem maj nrhiav cov khoom ntau dua. Ntxiv rau qhov DLC tus qauv rau cov khoom siv hluav taws xob hauv Teb Chaws Asmeskas, Cov European Union tseem tsim cov qauv tshiab tshiab qauv (Ecodesign Ua Hauj Lwm Npaj 2020), xav tau cov khoom siv teeb pom kev zoo kom ua tau li 85 lm / W ntawm lub teeb ci . Txawm hais tias tus cua ntsawj ntshab tseem nyob rau theem ntawm cov kev xav ntawm lub tswv yim, nws tau maj mam cov xim ntawm cov tuam txhab LED kom muaj teeb pom kev zoo siab.
Nyob rau hauv no sib, thawj-kab LED manufacturers nrog patent tiv thaiv thiab siab teeb technology, xws li Riyache, CREE, Lumileds, Osram, Eurolight thiab Seoul Semiconductor, yuav pab ncaj qha.
