Kutsatiridwa ndi nyali zowunikira za LED ndi nyali zamitundu yosiyanasiyana ya luso ndikugwira ntchito ngati malo oyambira kukula kwa "zolimba", zakhala zikukhutitsidwa pang'onopang'ono pempho la gwero lachikhalidwe, m'gulu lina lowunikira, kuteteza mphamvu ndi kuteteza chilengedwe. malo ogwiritsira ntchito akuchulukirachulukira kukhala "ofewa", mabizinesi azikhalidwe zamabizinesi akuwunikira nawonso akutenga nawo gawo pamsika wosiyanasiyana wounikira wa LED, kuyambira kufunafuna mabizinesi kusintha kwanjira. Kuphulika kwa chaka choyamba, iyi ndiye LED idzayambitsanso zinyalala zakuya zachikhalidwe? Mu 2011, chionetsero cha dziko mu Guangzhou padziko lonse kuunikira chilungamo monga chochitika pamwamba makampani, nthawi zambiri akhoza kukhoza kudutsa zambiri, ntchito makampani chionetsero - kwa nthawi yoyamba kukhala padziko lonse kuyatsa chionetsero pa nthawi yomweyo, dibon yekha kutsegula chionetsero. ya chiwonetsero cha LED idawonekeranso ngati chiwonetsero chachikulu kwambiri cha LED padziko lonse lapansi.
Katundu wa LED m'malo apamwamba mu kukula mutant
Monga owonera kwambiri padziko lonse lapansi (di) masiku ano m'badwo watsopano wa gwero la kuwala, LED chifukwa cha kuwala kwake kwakukulu, kutentha kochepa, moyo wautali, wopanda poizoni, imatha kugwiritsidwanso ntchito, monga mphamvu, yomwe imatchedwa kukula kwambiri. chiyembekezo cha gwero lounikira zobiriwira m'zaka za zana la 21. Katundu wa LED ku China adayamba m'zaka za 70 zazaka za zana la 20, podutsa zaka pafupifupi 40, dziko lathu lakhala lalikulu kwambiri padziko lonse lapansi opanga zowunikira komanso wachiwiri kugulitsa kunja kwamagetsi. Akuluakulu ku China (China) kumayambiriro kwa zaka za 2009 ndi unduna wa sayansi ndiukadaulo waku China adayambitsa kuyatsa kwa semiconductor "ten city wan light" pogwiritsa ntchito ziwonetsero za mzinda, polimbikitsa ndondomeko, kuwunikira komanso kuyamikira mabizinesi ambiri kuyambira pachiyambi. kukula kwa mafakitale, ndikuyambitsa "kutentha kwa LED" kwa mafunde. Pansi pa mfundo yolimbikitsa, kupanga kuyatsa kwa LED kumalimbikitsidwa kwambiri. Msika wowunikira wa LED mu 2011 pakukula mwachangu, kuyatsa kwa LED ndizomwe zimachitika The Times, opanga mwayi wopanda malire, atenga msika waukulu.
Gwero la kuwala kobiriwira, kuyatsa kwa LED kudzalowa m'malo mwa kuyatsa kwachikhalidwe
M'tsogolomu, kuyatsa kwa LED kudzalowa m'malo mwa zowunikira zachikhalidwe. Chowunikira choyaka cha LED ndi mtundu wa gwero lozizira lowala, palibe zowunikira zachikhalidwe zomwe zingapereke mvula yamatenthedwe, filament idawotchedwa ndi mitu ina, yokhala ndi moyo wautali komanso wokhazikika. Moyo wazinthu zowunikira za LED ndizokwera kuwirikiza kakhumi kuposa moyo wazogulitsa zachikhalidwe. Ndizinthu zaukadaulo wapamwamba kwambiri, zomwe zimayang'aniridwa ndi makina owerengera, zitha kukhala zambiri (geng) pulogalamu yabwino yapaintaneti ndipo zitha kukhala (k ě) mulingo nthawi iliyonse, chifukwa chake ndikoyenera kwambiri masiku ano (shu ) kukula kwa chidziwitso cha mawu. Chofunikira kwambiri ndikuti, zowunikira za LED ndizoyenera lingaliro loteteza chilengedwe. Chifukwa chake otsika mphamvu mowa, wa dc pagalimoto, magetsi ndi kuwala mphamvu kutembenuka akhoza kufika zana peresenti. Nthawi zambiri zowunikira, mphamvu zopitilira 80% kuposa zida zachikhalidwe zowunikira.
Mu 2010, mabungwe ogwirizana kwa kuyatsa kwa LED m'malo mwa nyali zachikhalidwe ndi nyali za nthawi ya funso loyendera zongoganiza, ulendo wofunsa "(ji ē), malinga ndi malonda a zipatso kuti athandize ndikupita patsogolo kwa LED kuti isinthe. kuwala kwachikhalidwe kumakhala ndi chiyembekezo. Anthu amaganiza kuti dipatimenti ya cuhk mkati mwa zaka 3, nyali zowunikira za LED ndi nyali zolowa m'malo mwa chiŵerengero cha kuyatsa kwachikhalidwe zimatha kufika 20%, ndipo mkati mwa zaka 3 mpaka 5 ndi 50%, ndipo patapita zaka 10 kapena 80%. Mu 2014, malinga ndi gwero laposachedwa lowunikira la semiconductor litenga 50% ya msika wapadziko lonse lapansi, mu 2016 kuyatsa kwa semiconductor kudzatenga 50% ya msika. Okhala m'makampani akuganiza kuti dipatimenti yayikulu mu 2020 zowunikira zamkati za LED kapena kuchuluka kwa ntchito kumatha kufika 50%.
Zachikhalidwe zopangira ndizogulitsa bizinesi yowunikira ya LED mtsogolo
Popeza 2010 nyali fulorosenti (kuphatikiza nyali zopulumutsa mphamvu), LED chipangizo limapanga (di) mu mtengo wa zipangizo zazikulu za osowa nthaka ikukwera kwambiri, apamwamba kwambiri (zothandiza) m: ng anafika 124%, mtengo akadali mu kusakhazikika kwa masiku ano. Poyankha, makampani kuti athandize kusanthula lingalirolo, mtengo wa deta yoyambirira, monga dziko losowa m'tsogolomu lidzapitirizabe kukwera. Chifukwa chosowa phosphor ufa ndi zinthu zazikulu zopangira, nyali ya fulorosenti, nyali zopulumutsa mphamvu, zida za LED zimagwiritsidwa ntchito mu encapsulation phosphor ufa, kukwera kwake kwamitengo kumawonetsa kufuna kwamakampani ogwirizana kwambiri.
Malinga ndi ziwerengero, 80% ya nyali zopulumutsa mphamvu padziko lonse lapansi zimapangidwa ku China, lero pali nyali zopitilira 3000 zopulumutsa mphamvu ndi mabizinesi ogwirizana m'dziko lathu, kutulutsa kwapachaka kwa nyali zopulumutsa mphamvu kokha kudzera 3 biliyoni, ndi vice ndi nyali zopulumutsa mphamvu pakati pa kupanga padziko lonse lapansi. Msika woyambira koma wapamwamba kwambiri umakhala ndi mitundu yakunja monga GE, philips, opanga ambiri aku China amangoyendayenda pamsika wotsika, kupatulira phindu. Ndipo mitengo yapakhomo yosowa padziko lapansi ikuyenera kuwononga mabizinesi aku China opulumutsa mphamvu monga dibon si phindu lalikulu. Ndi osowa lapansi ndi chimodzi mwa zinthu zazikulu zopangira zopangira zowunikira za LED, koma monga mtundu wa zinthu zatsopano, kuyatsa kwa LED komwe phindu lamasiku ano likadali lalitali, lofunikira limatha kupitilira 30%, ndipo kuchokera ku likulu, mtengo wamtengo wapatali wapadziko lapansi ndi zitsulo udzakwera chaka ndi chaka, koma likulu la dipatimenti yowunikira zowunikira za LED tchipisi mtengo udzakhala wokhazikika, ukhoza kuthetsa kukwera kwa mtengo. Pankhaniyi, akuti padzakhala mabizinesi ambiri kuti afulumizitse gulu la zinthu zowunikira za LED.
Makampani owunikira achikhalidwe kuti akulitse malonda a katundu wa LED akukwera
Back thumba dzulo kwa chaka, zoweta inflation kuthamanga kuwonjezeka, deta choyambirira ndi likulu la anthu limatuluka mosalekeza, ndi mpikisano kwambiri kwambiri makampani zoweta zounikira, ogwira ntchito malonda akwera kwambiri, makampani yunifolomu pang'onopang'ono anakhala mipata woonda phindu. Kwenikweni pakufuna kwa msika, kuphatikiza ndi chithandizo cha mfundo za boma, kukula kwa mafakitale owunikira kumakhala ndi kuthekera kwakukulu, kuchokera kumakampani ogwirizana omwe amagulitsidwa, kuwunikira kwa LED bizinesi yamtsogolo ndi phindu ku katundu ali ndi malo akulu komanso bata. Mu 2010, kuwala kwa dzuwa (Hua) Kukonzekera kwakukulu kuti tikwaniritse ndondomeko yapachaka ndi cholinga, ndalama zamalonda zapachaka ndi 2.17 yuan biliyoni, zomwe zakwaniritsa ndondomeko yathunthu ndi cholinga cha 102,04%, chinawonjezeka ndi 24.52%; Pa zoweta magetsi kuwala gwero makampani kutsogolera udindo makamaka, foshan kuyatsa mu 2011 kupititsa patsogolo malonda malonda. Dulaninso kapangidwe kazinthu zonse, tsegulani mwamphamvu ndikupanga zinthu zopulumutsa mphamvu ndi zinthu zamtengo wapatali, monga nyali yachitsulo ya halide, nyali ya LED, ndi zina zambiri, kudzera mukusaka mosalekeza kwa ma lead pamsika wamba. Kuunikira kwadzuwa kuti kufulumizitse kupita kumalo owunikira omwe akutuluka kuchokera ku kuyatsa kwachikhalidwe, mercury ndi kiyi kulimbikitsa kafukufuku wa nyale zopulumutsa mphamvu zachilengedwe pazatsopano ndikupita patsogolo kwa zowunikira za LED.
Kodi akatswiri aneneratu kuti m'tsogolomu zaka 10 msika wounikira wa LED udzakhwima pang'onopang'ono, komanso kuunikira kwachikhalidwe kwa nyali zowunikira za LED ndi nyali ndizofunikira kwambiri pakusintha kwazaka 10. M'gulu Hong Kong chaka chatha leishi kuunikira 2010 kuchuluka ndalama 54,3% kuyambira chaka chapitacho kwa $470 miliyoni, kampani kulimbikitsa kwa Kukwezeleza mphamvu yopulumutsa kuwala gwero; Kugulitsa kwazinthu zamagetsi zamagetsi kudakwera ndi 64,5%, makamaka ZhanEn muzinthu zokhala ndi nyali ndi nyali ndi gwero lowunikira lothandizira kuwonjezeka kwa malonda. Posachedwapa leishi kuyatsa lalikulu Launch mankhwala LED kuyatsa, ntchito kukula LED kuyatsa kutsimikiza kwa katundu. Zitha kuwonedwa kuchokera ku chidule cha zomwe tafotokozazi, luso lowunikira bizinesi yowunikira moyenera, tsatirani mwachangu pamalingaliro amtundu wa LED mafunde, kukulitsa kukula kwa bizinesi yowunikira za LED. Kuunikira kwachikhalidwe kukuyenda ndi bizinesi yatsopano.
