Kulandelwa izibani ezikhanyisayo ze-LED nezibani zamakhono ahlukahlukene kanye nokusebenza njengendawo okugxilwe kuyo yokukhula “kokuqina”, kuye kwaneliseka kancane kancane isicelo somthombo wokukhanya wendabuko, esigabeni esithile sokukhanyisa, ukongiwa kwamandla nokuvikelwa kwemvelo njengoba indawo okugxilwe kuyo yokusetshenziswa iya ngokuya yaziswa kakhulu “ethambile”, amabhizinisi emboni yokukhanyisa yendabuko nawo abandakanyeka emakethe yokukhanyisa ama-LED ahlukahlukene, aqala ukuphuthaza amabhizinisi ukuguqulwa kwendlela. Ukugqashuka konyaka wokuqala, lena LED uyophinde uqale udoti izibani bendabuko? Ngo-2011, umbukiso wezwe e-guangzhou international lighting fair njengoba umcimbi ophezulu wemboni, ngokuvamile ungaba kungase kudlule ulwazi, imboni yokusebenza ivelele - ngokokuqala ngqa ukuba ibe umbukiso wokukhanyisa omkhulu kunawo wonke emhlabeni ngesikhathi esifanayo, i-dibon eyodwa kuphela evula umbukiso wombukiso we-LED uphinde wavela njengombukiso omkhulu we-LED emhlabeni.
Impahla ye-LED ezindaweni eziphezulu ku-mutant yokukhula
Njengoba i-(di) ebukwa kakhulu emhlabeni namuhla isizukulwane esisha somthombo wokukhanya, i-LED ngenxa yokukhanya kwayo okuphezulu, inani eliphansi lokushisa, impilo ende, engenabuthi, ingathatha ukusetshenziswa kabusha, njengamandla, okubizwa ngokuthi ukukhula kakhulu. ithemba lomthombo wokukhanya wokukhanyisa oluhlaza ekhulwini lama-21. Impahla ye-LED eChina yaqala eminyakeni engama-70 yekhulu lama-20, idlula ngokukhula kweminyaka ecishe ibe ngu-40, izwe lethu selingumkhiqizi omkhulu wokukhanyisa izibani kanye nomkhiqizi wesibili ngobukhulu wokukhanyisa ugesi. Iziphathimandla eShayina (China) ekuqaleni kweminyaka ka-2009 ngumnyango wesayensi nobuchwepheshe waseShayina wethula ukukhanyisa kwe-semiconductor ye-"ten city wan light" kusetshenziswa idolobha lokubonisa, ekukhuthazeni inqubomgomo, babuyekeze futhi bazise amabhizinisi amaningi aqala kusukela ekuqaleni amandla okukhula embonini, futhi kwaqala "ukushisa kwe-LED" kwamagagasi. Ngaphansi kwenqubomgomo yokugqugquzela, ukukhiqizwa kwezibani ze-LED kukhuthazwe kakhulu. Imakethe yezibani ze-LED ngo-2011 ngesikhathi sokukhula okusheshayo, ukukhanyisa kwe-LED kuwumkhuba weThe Times, abakhiqizi bokukhiqiza abangenamkhawulo, bathatha imakethe enkulu.
Umthombo wokukhanya okuluhlaza, ukukhanyisa kwe-LED kuzothatha indawo yokukhanya kwendabuko
Ngokuzayo, ukukhanyisa kwe-LED kuzothatha indawo yemikhiqizo yokukhanyisa yendabuko. Umkhiqizo wokukhanyisa we-LED oshisayo uwumthombo wokukhanya obandayo, ayikho imikhiqizo yokukhanyisa yendabuko ezoletha imvula eshisayo, i-filament yashiswa nezinye izihloko, ngokufaneleka kokuphila isikhathi eside nokuqina. Impilo yemikhiqizo yezibani ze-LED iphakeme ngokuphindwe izikhathi eziyishumi kunempilo yomkhiqizo wendabuko. Okwemikhiqizo esezingeni eliphezulu yobuchwepheshe obusezingeni eliphezulu, ngaphansi kolawulo lomshini wokubala, mhlawumbe kungaba ngaphezulu (geng) okuhlela izinhlelo ze-inthanethi futhi kungaba (k ě) ezingeni noma kunini, ngakho kufanelekile kakhulu inombolo yanamuhla (shu ) ukukhula kolwazi lwamagama. Okubaluleke kakhulu ukuthi, imikhiqizo yokukhanyisa ye-LED efanelekile umqondo wokuvikela imvelo. Ngenxa yokusetshenziswa kwayo okuphansi kwamandla, kungokwe-dc drive, ukuguqulwa kwamandla kagesi kanye ne-optical kungafinyelela amaphesenti ayikhulu. Ezimweni eziningi zokukhanyisa, amandla angaphezu kuka-80% kunemikhiqizo yokukhanyisa yendabuko.
Eminyakeni ka-2010, ama-ejensi ahambisanayo okukhanyisa kwe-LED ukuze ashintshe izibani zokukhanyisa zendabuko nezibani zesimiso sesikhathi sombuzo wokuvakashela ukunyakaza kokuqagela, ukuvakashelwa kombuzo "(ji ē), ngokusho kwemboni yezithelo ukusiza nokuqhubeka kwe-LED ukuze ithathe indawo. ukukhanya kwendabuko kunethemba elikhulu. Abantu bacabanga ukuthi umnyango we-cuhk phakathi neminyaka emi-3, izibani zokukhanyisa ze-LED nezibani zokushintsha isilinganiso sokukhanyisa kwendabuko zingafinyelela ku-20%, futhi phakathi neminyaka emi-3 kuya kwemi-5 ngu-50%, futhi ngemva kweminyaka engu-10 noma kuze kufike ku-80%. Ngo-2014, ngokomthombo wakamuva wokukhanyisa we-semiconductor wokuqagela uzothatha u-50% wesabelo semakethe yomhlaba, ngo-2016 ukukhanyisa kwe-semiconductor kuzothatha u-50% wesabelo semakethe. Abangaphakathi embonini bacabanga ukuthi umnyango omkhulu ngo-2020 imikhiqizo yokukhanyisa yasendlini ye-LED noma izinga lomsebenzi lingafinyelela ku-50%.
Izinto ezingavuthiwe zendabuko ziyi-bullish yebhizinisi lokukhanyisa i-LED esikhathini esizayo
Kusukela ngo-2010 izibani ze-fluorescent (kuhlanganise nezibani zokonga amandla), idivayisi eholelekile ikhiqiza (di) ngentengo yezinto zokusetshenziswa eziyinhloko zomhlaba ongavamile ikhuphuka kakhulu, ephakeme kakhulu (ewusizo) m: ifinyelele ku-124%, intengo isekhona ukuntengantenga kwanamuhla. Ekuphenduleni, imboni ukusiza ukuhlaziya umcabango, intengo yedatha yasekuqaleni, njengomhlaba ongavamile esikhathini esizayo uzoqhubeka nokukhuphuka ngokuqhubekayo. Ngenxa yempushana yomhlaba engavamile i-phosphor powder iyimpahla eyinhloko eluhlaza, isibani se-fluorescent, izibani zokonga amandla, amadivaysi e-LED asetshenziswa ku-encapsulation phosphor powder, ukukhuphuka kwentengo yawo kubonisa intando ye-industrial chain nomthelela omkhulu.
Ngokwezibalo, ama-80% ezibani zokulondoloza amandla emhlabeni enziwa eChina, namuhla kunezibani ezingaphezu kuka-3000 ezonga amandla kanye namabhizinisi ahambisanayo ezweni lethu, ukukhishwa kwaminyaka yonke kwezibani zokonga amandla kuphela ngezigidi eziyizinkulungwane ezintathu. i-vice izibani ezonga amandla phakathi kokukhiqizwa komhlaba wonke. Imakethe eyisisekelo kodwa esezingeni eliphezulu ithathwa yimikhiqizo yangaphandle njenge-GE, i-philips, iningi labakhiqizi baseShayina lizulazula emakethe esezingeni eliphansi, linciphisa inzuzo. Futhi izintengo zasekhaya zomhlaba ezingavamile zibophezele enanini elikhulu lokushwabadela amabhizinisi ase-China okonga amandla njenge-dibon akuyona inzuzo ephezulu. Ingabe umhlaba ongavamile ungenye yezinto eziyinhloko zokusetshenziswa kwemikhiqizo yokukhanyisa kwe-LED, kodwa njengohlobo lwemikhiqizo emisha, ukukhanyisa kwe-LED inzuzo yanamuhla isephezulu kakhulu, eyisisekelo ingaba ngaphezu kwama-30%, futhi ngokombono wemali, i intengo yezinto ezingavamile zomhlaba nezensimbi izokhuphuka unyaka nonyaka, kodwa inhloko-dolobha yomnyango wemikhiqizo yezibani ze-LED intengo enkulu yama-chips izoba nesimo esihlala njalo, inganciphisa ukukhuphuka kwentengo. Kulokhu, kulinganiselwa ukuthi kuzoba namabhizinisi amaningi azosheshisa esigabeni semikhiqizo yokukhanyisa i-LED.
Izinkampani zokukhanyisa zendabuko zokwandisa ukuthengiswa kwempahla ye-LED kukhuphuka
Isikhwama sangemuva izolo unyaka, ingcindezi yokwehla kwamandla emali yasekhaya ikhuphuka, idatha yokuqala kanye nenani labantu likhuphuka ngokuqhubekayo, ukuncintisana okushubile embonini yokukhanyisa yasekhaya, amandla ebhizinisi lebhizinisi akhuphuke kakhulu, imboni efanayo kancane kancane yaba yimali encane yenzuzo. Ngokuyisisekelo esidingweni semakethe, kuhlangene nokusekelwa kwenqubomgomo yezwe, ukukhula kwemboni yokukhanyisa kuqukethe amandla amakhulu, kusukela ezinkampanini ezihambisanayo ezisohlwini lwezinkampani ezithengisayo, ukukhanyisa kwe-LED ibhizinisi lesikhathi esizayo kanye nenzuzo yempahla inesikhala esikhulu nokuzinza. Ngo-2010, ukukhanyisa kwelanga (hua) super ukuhlela ukuze kuzuzwe uhlelo lonyaka ngenhloso, imali engenayo yebhizinisi yonyaka ingama-yuan ayizigidi eziyizinkulungwane ezingu-2.17, ifinyelelwe uhlelo oluphelele ngenjongo ye-102.04%, inyuke ngo-24.52%; Embonini yasekhaya yomthombo wokukhanya kagesi ehamba phambili ngokuyisisekelo, ukukhanyisa kwe-foshan ngo-2011 ukuze kuqhutshekwe nokwandisa ibhizinisi lokuthekelisa. Sika futhi ukwakheka komkhiqizo wonke, uvule ngamandla futhi ukhiqize imikhiqizo yokonga amandla kanye nemikhiqizo enenani eliphakeme, njengesibani sensimbi se-halide, isibani se-LED, njll., ngokuphishekela amaledi emakethe yabantu abavamile. Ukukhanyisa kwelanga ukuze kusheshiswe endaweni yokukhanyisa evelayo kusukela ekukhanyisweni kwendabuko, i-mercury nokhiye ukuze kuthuthukiswe ucwaningo lwamalambu okonga amandla emvelo lwemikhiqizo emisha kanye nenqubekelaphambili yokukhiqiza imikhiqizo ekhanyayo ye-LED.
Iba nochwepheshe babikezele ukuthi eminyakeni eyi-10 ezayo imakethe yokukhanyisa i-LED izovuthwa kancane kancane, futhi ukukhanya kwendabuko kwezibani zokukhanyisa ze-LED kanye nezibani kuyimqoka kakhulu empumelelweni yoguquko lweminyaka eyi-10. Ezisohlwini Hong Kong ngonyaka odlule ukukhanyisa leishi 2010 ukwanda kwengeniso 54.3% kusukela ngonyaka odlule kuya $470 million, inkampani ukuqinisa for ukukhuthazwa umthombo wokukhanya ukonga amandla; Ukuthengiswa kwemikhiqizo kagesi ekhanyisayo kukhuphuke ngo-64.5%, ikakhulukazi i-ZhanEn emkhiqizweni onamalambu nezibani nomthombo wokukhanya osekela ukukhuphuka kokuthengisa. Muva nje i-leishi ikhanyisa ukwethulwa okukhulu kwemikhiqizo yokukhanyisa ye-LED, ukukhula komkhakha we-LED okukhanyisa ukuzimisela kwendawo. Kungabonakala kulesi simo esifingqiwe esingenhla, ikhono lebhizinisi lokukhanyisa elivamile lenzuzo ngokwanele, ukulandela ngenkuthalo uhlelo lomkhiqizo lwe-LED, ukwandisa ububanzi bebhizinisi lokukhanyisa i-LED. Ukukhanyisa kwendabuko kugeleza nebhizinisi elisha.
