Sikholelwa ukuthi imboni ye-LED e-China inamathemba amahle entuthuko, ngokusekelwe kulawa maphuzu alandelayo: Okokuqala, ngokwethekhnoloji, ubuchwepheshe be-LED bunebhodlela eliphezulu.

ukukhula, izici zomkhawulo ophansi wocwaningo, ukunqwabelana kwasekhaya kwesikhathi eside endaweni ye-semiconductor yezinsiza zocwaningo kungaba usizo ngesisekelo esihle sokuqhubeka nocwaningo.Nakuba ukukhiqizwa kwama-cireuits ahlanganisiwe asekelwe ezingeni elibuthakathaka, eliphansi kakhulu lobuchwepheshe, kodwa amanye amabhizinisi asekhaya ukujoyina abasebenzi baphesheya kwezilwandle, ayaqhubeka nokwenza intuthuko kwezobuchwepheshe, izinga lobuchwepheshe lamabhizinisi asekhaya anezinkampani ezinhle ezinezinga lethekhnoloji laseTaiwan noma elingaphansi elifana nezinkampani zamazwe ngamazwe. ngokuphelele ubelokhu enciphisa igebe;Okwesibili, ukutshalwa kwezimali kwe-LED ngokuqhathaniswa okuncane kokuqala kuzoba yizitshalo eziyizigidi eziyi-100, amabhizinisi asekhaya azongena embundwini wezinga eliphansi, elifinyeleleka kalula ekuthuthukisweni nasekukhiqizeni amasekethe adidiyelwe kanye nabakhiqizi bephaneli ye-liquidcrystal kalula emashumini ezigidigidi zezigidigidi zama-yuan ekutshalweni kwezimali " okungabalulekile” ukufinyelela okulula kumabhizinisi asekhaya ukuze akhe amaqoqo ezimboni, vele, kungaholela ekuqhudelaneni okunonya kanye nasesigabeni esithile sokuthuthuka kokudidiyelwa kwezimakethe;Okwesithathu, imakethe yasekhaya inkulu, imakethe ye-LED iyimakethe yokukhanyisa ejwayelekile elandelayo, umthamo wemakethe, imakethe yabathengi, ehlakazekile futhi enzima ukwakha i-monopoly, indawo enkulu yokuhlala yamabhizinisi asekhaya;Okwesine, ezinye izinkampani zinomnyombo wamalungelo e-intellectualproporty, njenge-crystalline silicon photo voltale aubatrate can.

Amaphrojekthi we-GaN-ray, i-Dallan Road, i-aron yase-United States kanye nomnyombo wobuchwepheshe be-chip, inokuncintisana komhlaba wonke kwalawa mabhizinisi ekuthuthukisweni kobuchwepheshe Emphumeleni wokubusa ngendlela elula futhi ekhuthaza ukukhula okunempilo kwemakethe yebhizinisi yasekhaya; amahlanu, ngemuva kokuvuthwa. yethekhnoloji, ukupakishwa kwe-LID kwe-downatream kanye namadivayisi angumkhiqizo ocindezela abasebenzi, ukuthuthukiswa kwezwe elikhulu nge-advantago yezindleko zabasebenzi.

Inqubo yentuthuko evela embonini ye-LED, ukuthengiswa komhlaba wonke kwe-LED ngokusho kwemakethe njengamanje kuyimakethe enkulu yokukhanya komakhalekhukhwini, ukukhula kokuthengiswa kwamaselula kwehla, kanye nesikrini se-OLED kumakhalekhukhwini we-TFT-LCD sereen ukuthuthukisa ukungena izinga lokukhula kwe-LED emhlabeni jikelele.Inqubekelaphambili yezobuchwepheshe ngenxa yokunciphisa izindleko esikhathini samanje (kanye

pre-2010) akwanele ukuvumela ukufinyelela okugcwele ukusetshenziswa okuvamile kwe-LED lightingmarket, ukukhula komhlaba wonke kuzoba incwadi yokubhalela elandelayo, i-LCD.Ukukhanyisa kabusha kwe-TV, nezimakethe zezimoto ezinemakethe ye-backlight yangaphakathi yemoto.Iphaneli ye-LCD emihlanu ephezulu emhlabeni (LG Philips, Samsung, AUO, CMO kanye ne-Sharp) esezingeni eliphezulu lobuchwepheshe be-LED, umthamo omkhulu wokukhiqiza eJapan, eTaiwan naseNingizimu Korea, i-BOE yasekhaya kuphela, ugesi wepholishi kanye namaphaneli amahlanu e-Dragon PY amathathu. imigqa, ulayini wokukhiqiza we-Shanghai Tianmaproduction wesizukulwane esingu-4.5 uzokwazi ngemuva kwesidingo sokukhanyisa kwe-LED, kodwa isidingo sisonke asinamandla, izinkampani zasekhaya zingena ku-LCD panel backlight LED LED supply chain chain akumele zibe yiphaneli enkulu kakhulu yokukhanyisa i-backlight nge-markot yocingo lweselula. I-quito iyafana.

Ukusetshenziswa kwemakethe yamaShayina kulesi sigaba ikakhulukazi ekukhanyisweni kwezakhiwo, isibonisi sangaphakathi nangaphandle, ngokususelwa kuzizathu ezingenhla, amandla amakhulu egagasi elilandelayo angase abe khona kulezi zimakethe, kodwa kumakhalekhukhwini, ukukhanya okuncane kwe-LCD kwe-backlight, imoto. ukungena kuzokwanda, futhi ezinye izimakethe ezihlakazekile ezifana nokukhanyisa kwe-spepelal zizovuleka nakakhulu (izindleko zezidingo zokukhanyisa okukhethekile zokukhanyisa okuvamile-azizimbi kangako).Ngemuva kokubekwa lapho eminyakeni embalwa edlule, amarobhothi e-LED athandwa kakhulu, njengoba impilo ye-LED yinde, isikhathi esifushane kuba nzima kakhulu ukuwashintsha.umcimbi womsebenzi omkhulu, okwenza amarobhothi e-LED abe nesikhathi sesidingo esiphansi;imakethe enkulu yasekhaya ye-sedan, kodwa ephakeme, ubude bomjikelezo wokunikeza izitifiketi, inqobo nje uma kunekhwalithi yomkhiqizo enhle kakhulu, izibani zemoto zasekhaya zasekhaya ukukhanya kwe-LED kanye nesidingo esikhulu semakethe nokukhula kwesidingo kule makethe kuzinzile uma kuqhathaniswa;kanye nesibonisi se-LED okulula ukukuhlanganisa, ukusetshenziswa kwamandla aphansi, ukukhanya okuphezulu, njll. sekusetshenziswe kabanzi kumabhange, izibambiso, izikwele, iziteshi zikaloliwe, izindawo zezemidlalo, ikusasa lale makethe lisenamandla amakhulu okukhula;Emidlalweni Yama-Olympic, I-World Expo, inani lemibukiso yasebusuku yedolobha lephrojekthi, eholwa yi-National Semiconductor Lighting Project, kanye nezici eziningi ezinhle, njengokukhuthazwa, imakethe yezibani zezakhiwo kuseyithemba elibanzi.

Ngokuvamile, izinkampani ezinkulu zamazwe ngamazwe zigxile emakethe “elungile” yemakethe ehlosiwe esezingeni eliphezulu, egxile kakhulu, kanye nokukhanya okuvamile kwemakethe enkulu engase ibe khona, futhi eminye yemikhiqizo izoba yisidingo esiphansi sobuchwepheshe sokuthi ukulawulwa kwesikhathi esizayo kwezindawo ezimisiwe. Imvelo yemakethe ibuthakathaka kakhulu ngenxa yenani elikhulu lamalungelo obunikazi, ungakhathazeki ngekusasa lalingekho emakethe kulesi sigaba ukuze ungaqhubeki nokukhiqiza amandla (ngenyanga ukuya ku-Nichia 500kk, Toyoda Gosei noCree babengu-350kk no-300kk) ,futhi ugxile kubuchwepheshe bokuhola izitayela zemakethe, Lapho ubuchwepheshe buvuthwe ngokwanele ukuba bulingane nemakethe ekukhanyeni okuvamile, i-itis ilinganisela ukuthi amandla ayo okukhiqiza azoba ngokushesha futhi ngesikhathi esifanayo ukunciphisa amalayisense angaphandle.Lesi "sikhungo - periphery" somncintiswano kulindeleke ukuthi sigcine isikhathi eside.

Njengamanje, abakhiqizi abakhulu emakethe ye-Mainland, uma ukwesaba ukuthunyelwa kwamanye amazwe kuzobhekana nezinselelo ezimbili: Okokuqala, izinkampani ezinkulu zamazwe ngamazwe ezisemacaleni obunikazi (ikakhulukazi okuluhlaza okwesibhakabhaka nokumhlophe), empeleni, inqobo nje uma ubukhulu obuthile, kungakhathaliseki ukuthi' ukuthekelisa futhi ukuthi ilungelo lobunikazi lizohlangabezana nezinselelo, kodwa ukuthunyelwa kwelungelo lobunikazi kwamanye amazwe

amacala maningi amathuba okuthi inani;Okwesibili, ukuncintisana kwabanye abathengisi bangaphandle, ikakhulukazi abakhiqizi eTaiwan, abakhiqizi bendabuko baseTaiwan balandela isu labo - nobuchwepheshe balandela izinkampani zamazwe ngamazwe, ngesikhathi esifanayo ngcono kakhulu ukukhiqiza, ukunciphisa izindleko namandla okukhiqiza eTaiwan i-chip yokuqala emhlabeni, kukhona inqwaba yezimboni ezifana ne-HonHai enkulu, i-Mau, ingqikithi yokuba kuhle ukungena kule ndawo, ingaba nomthelela kwikusasa le-Talwan LED chip fluctuatlons yentengo yemakethe yomhlaba wonke, Njengoba kunikezwe isidingo esikhulu semakethe yasekhaya, izitshalo ze-chip zasekhaya, ngisho noma i-1t ingakwazi ukuthembela emakethe yasekhaya yokuthuthukiswa kokwanele, uma i-photovoltalc ihlanganisa ukufinyelela okungenamkhawulo phesheya kwezimakethe zasekhaya, izinkampani zasekhaya zizobhekana nezingcindezi eziqhubekayo zokuncintisana, okuthi esikhathini eside amabhizinisi asekhaya 1 isitatimende esibi kakhulu.Imboni ye-LED iyakhula kulesi sigaba, kodwa futhi ukuhlelwa kombono we-LED makersa wokutshalwa kwezimali kwasekhaya, kwamanye amazwe e-Mainland ukuze kujabulele ama-taxicentives, amabhizinisi asekhaya ukuze aqhudelane endaweni engalingani ukuze afake i-narket yasekhaya kubatshalizimali bangaphandle kufanele akhuthazwe ukuthi akhe izimboni I-China ukuze ihlanganyele ekufinyeleleni, ubuchwepheshe be-chip core, obufana namabhizinisi, lawa mabhizinisi angakhuthaza ukuqeqeshwa kwabasebenzi futhi akhuphule izinga lamakhono jikelele;kufanele ikhawulelwe kulawo maphakheji ezweni, i-epitaxial, i-chip, njengengxenye yobuchwepheshe obuyisisekelo bomsebenzi emakethe yangaphandle evela ebhizinisini, Uma ikhadi lebhizinisi elinjalo lizo zonke izindawo eziyinhloko, futhi amabhizinisi endawo angazijabuleli izinzuzo zenqubekelaphambili yezobuchwepheshe, ukuthuthukiswa kanye nesikhala esilinganiselwe, ngiyesaba ukuthi bazokhwabanisela ukuthembela empini yamanani, akunzima kangako ukuzitholela into yabo, ngakho-ke bhekana nengxenye kuphela yephakeji yamanje e-China ukukhawulela ukutshalwa kwezimali kwamanye amazwe, njengentela yokungenisa ekhokhwa ku-chíp.

Kusuka ecaleni lelungelo lobunikazi elithintekayo, akukubi, inqobo nje uma izimbangi zethu eziyinhloko, kufanele zikhokhe, sisaqhudelana esiqalweni esifanayo.Okukhulu kwaseTaiwan okuhilela ifektri ye-chip ye-LED eluhlaza okwesibhakabhaka nokumhlophe ohlelweni lokukhula kusebenzisa i-LED yamacala, kwafinyelela esivumelwaneni esinqumweni sokuthola amalungelo obunikazi, kuqhubeke ukukhula.Impendulo engcono kakhulu iwukwenza kulesi sigaba isilinganiso esikhulu, ukufinyelela kumalungelo obunikazi, kuyilapho ngesikhathi esifanayo iqinisa i-R & D yayo ukuze Kuthuthukiswe ukuqulwa kwamalungelo obunikazi emandleni okuxoxisana ngokunikeza amalayisense ahlukahlukene.Amabhizinisi asekhaya ngokobukhulu, i-Xiamen San'an ingase iqalise ukukhula “kobhapathizo” lokuqala.

Ukuncintisana kwezimboni esikhathini esizayo i-wi11 kuncike ezicini ezimbili, okokuqala, ubuchwepheshe, okuhlanganisa ukuthuthukisa ukusebenza kahle kokukhipha ukukhanya kanye nokunciphisa izindleko zobuchwepheshe ukuze kuthuthukiswe ubuchwepheshe bedivayisi yamandla, ukuqondiswa komgwaqo kukhona ukunwetshwa kobuchwepheshe obukhona, kodwa kanye nemizila engaba khona yobuchwepheshe obusha. ;kuhlanganise nokufinyelela emikhiqizweni yobuchwepheshe bezinga eliphezulu,_kanye nezinhlelo zangaphandle ezifana nedizayini yokukhanyisa kanye nomklamo wama-chip oqhutshwa ubuchwepheshe;Okwesibili, isikali, ngakolunye uhlangothi, ngenxa yezinga elikhulu lokunciphisa izindleko, amandla emakethe okuxoxisana aqinile; Ngakolunye uhlangothi, izinhlanganisela ezine-IC wafer ukukhiqizwa kwe-silicon esetshenzisiwe yehluke kakhulu, noma ngabe isandiso ekukhiqizeni okufanayo siphuma ekusebenzeni kwe-chip. ingase yehluke kakhulu, edinga ukungaguquguquki okuphezulu kakhulu kwezindawo zokufaka izicelo (ezifana ne-atypical LCD backlight), ukunwetshwa kwe-Kunengxenye kuphela yokuhlangabezana nezidingo, kodwa amabhizinisi amakhulu, inani lamazinga esakhiwo semakethe, angeke ahambisane. nezimfuneko zokuqoshwa kwemakethe okukhethekile kwe-chip produeta kwenye imakethe, inani eliphelele lenkampani ukuze kuncishiswe ukonakala okugcwele.

Imboni ye-LED ikusasa eliqhakazile, kodwa kuphela ezicini ezimbili ezishiwo ngenhla zebhizinisi elihamba phambili lemboni yinkosi yesikhathi esizayo.

Isiphetho: Inkampani iphawule, i-domostio enterprisos kufanele ikhathazeke ngani?

Kuwo wonke uchungechunge lwemboni ye-LED futhi yikuphi ukukhathazeka kwebhizinisi?Kusukela ohlelweni lokuthuthukiswa okupheleleyo, izinkampani ezinhlanu zinenani elikhulu lokutshalwa kwezimali.

Isigaba samalungelo empahla yengqondo yibhizinisi eliwumongo.Igumbi lokuthuthukiswa kwamabhizinisi anjalo eNyuvesi yasekhaya yaseNanchang esungulwe isikhwama esihlanganyelwe sokulingana kwangasese icrystal ingaba ummeleli ojwayelekile we-photoelectric, i-photoelectriccrystal ingenziwa ngobuchwepheshe be-GaN epitaxial Blu-ray obusekelwe ku-silicon ukuya kwabaphezulu abathathu abaluhlaza okwesibhakabhaka emhlabeni. I-Light one process technology ukugqabula amalungelo obunikazi angaphandle u-Nichia noCree blockade, inkampani imiswe eduze nezinga lamanje -lomkhakha udinga ukuhlolwa;enye I-Luming forDalian, inkampani ngokutholwa kwabakhiqizi bama-chips baseMelika be-LED ukwenza ama-chips AXT akhule, ukufinyelela kubuchwepheshe obuyinhloko obunamalungelo obunikazi obungaphezu kwama-40, kanye nethimba lezobuchwepheshe.Ukwengeza, i-Dalian Luming ihileleke emhlabeni ongavamile kusukela into yokuqala ekhipha ukukhanya, emhlophe ekuhlanganiseni kwempushana ye-fluorescent esetshenziswa ekukhiqizeni onqenqemeni, ingenye yemikhiqizo yomhlaba wonke abambalwa kuphela abangakhiqiza izinto ezikhipha ukukhanya ezikhipha ukukhanya.Ngaphezu kwalokho, amathuba e-R & D Luming manje eyimpushana engavamile-earthfluorescent, ukuphumelela kwe-Nichla, ubuchwepheshe bokukhanya obumhlophe be-Oaram, obufana namalungelo obunikazi, embonini yasekhaya Ukungena ekugqameni kokukhanya kwe-LED okuvamile emigomeni yokugcina!Ukukhanyisa kwe-LED okumhlophe inqobo nje uma "isikhubekiso" esikhulu ezimbili - i-Blu-ray patent kanye ne-white patent ukuze kwenziwe impumelelo, imboni yasekhaya ye-LED ikusasa eliqhakazile kuyo yonke imboni yasekhaya ukuhlola ikhono lemboni.

Amanye amabhizinisi embonini ye-chip nobuchwepheshe ukuze alandelele ibhizinisi elenza ngempumelelo.Ikhono lokwenza umklamo wangempela we-chip kanye nokucutshungulwa kwesandiso esiluhlaza sosayizi othize futhi sigxile kakhulu ku-Saman Xiamen, Dalian Road, United States (Lumingsubsidiaries), izinkampani ezimbalwa ezifana ne-士兰 微, isikali samanje sokukhiqiza nge-LED-ray kuphela iSaman.
