Pambuyo pazaka zachitukuko, makina amakampani aku China aku LED ayamba kutha.Komabe, Wang Ying, katswiri wa CCID Consulting's Semiconductor Industry Research Center, adauza atolankhani masiku angapo apitawo kuti kuyang'ana mndandanda wamakampani a LED, chifukwa cha luso lapamwamba laukadaulo komanso zofunikira zazikulu zamakampani akumtunda, makampani ochepa apakhomo akukhudzidwa.Chifukwa chake, pali makampani ochepa m'makampani akumtunda.Makhalidwe aang'ono.Mosiyana ndi izi, ma CD otsika ndi ntchito ali ndi ndalama zochepa komanso zofunikira zaukadaulo zamakampani, zomwe zimagwirizana ndi zomwe makampani apakhomo ali nazo komanso ukadaulo wofooka.Choncho, chiwerengero cha makampani zoweta chinkhoswe ma CD ndi ntchito ndi lalikulu.Izi zapangitsa kuti makampani apakhomo a LED amakhala otsika kwambiri, ndipo makampani akukumana ndi zovuta zamtengo wapatali kwa nthawi yayitali.

Malinga ndi kumvetsetsa kwa mtolankhani, pakali pano, ndi chiyambi cha National Semiconductor Lighting Project, momwe makampani a LED akusintha.Makampani opanga ma LED akumtunda adakula mwachangu, ndipo chitukuko chamakampani a chip ndichokopa kwambiri.Koma pakuwona kukula kwa mafakitale, kulongedza akadali ulalo waukulu kwambiri wamakampani pamakampani a LED.Mu 2016, mtengo wonse wamakampani a LED mdziko langa unafika 10.55 biliyoni ya yuan, pomwe mtengo wake wamakampani opanga ma CD udafika 8.75 biliyoni.Wang Ying adasanthula kuti kufunikira kwa msika komwe kukukulirakulira komanso thandizo lamphamvu la boma ndizinthu zabwino zowonetsetsa kuti makampani a LED akukula.M'zaka zaposachedwa, misika yogwiritsira ntchito ma LED monga zowonetsera, kuyatsa malo, magetsi apamsewu, magalimoto ogwiritsira ntchito magalimoto, ndi zowunikira kumbuyo zawonekera mwachangu.Kuwongolera kosalekeza kwa zofunikira zowoneka bwino za LED m'misika yomwe ikubwera kwadzetsa kufunikira kwa zinthu zapakati mpaka zapamwamba.Ndi kuchuluka kwa kufunikira kwa msika, kukweza kwa zida zamakampani a chip za LED kukuchulukirachulukira, ndipo zida za chip za LED zikupita kumapeto kwathunthu.Kumbali inayi, kutukuka kwachangu kwamakampani opanga ma LED kumaperekanso kufunikira kwa msika wotakata kwa tchipisi ta LED, komwe kumapereka malo abwino akunja opititsa patsogolo makampani a LED.

Boma laperekanso chithandizo champhamvu pa chitukuko cha mafakitale a LED.Mu 2016, molingana ndi chitukuko cha dziko langa semiconductor kuyatsa makampani, m'madipatimenti zogwirizana anakonza semiconductor kuyatsa makampani ndondomeko chitukuko ndi njira zamakono chitukuko cha 2016 akufuna kuti ndalama mu tchipisi LED adzakhala mlandu 20% ya ndalama makampani LED, ndipo cholinga cha kafukufuku chidzakhala pa tchipisi ta GAN.Kupanga ndi kafukufuku wa chip ndi chitukuko.

Ngakhale pali kufunikira kwakukulu kwa msika ndi chithandizo champhamvu kuchokera kumadipatimenti oyenerera, n'zosakayikitsa kuti makampani opanga zida za LED akadali ndi zovuta zachitukuko monga kusowa kwaukadaulo wapakatikati, kusowa kwa luso laukadaulo, kutsika kwazinthu, ndi zida zofooka zopanga zodziyimira pawokha.Momwe mungathetsere mavuto omwe ali pamwambawa ndi chinsinsi cha chitukuko chokhazikika, chathanzi komanso chofulumira cha makampani a LED a dziko langa.

Wang Ying amakhulupirira kuti kukula kwachangu kwa makampani opanga zida za LED kudzakulitsa kukweza kwamakampani a LED.Mu ndondomeko ya chitukuko cha makampani LED Chip, mankhwala oyambirira anali makamaka tchipisi kuwala wamba, ndipo panali opanga ochepa monga Nanchang Xinlei.Pambuyo pa 2013, opanga ma chip omwe akuimiridwa ndi Xiamen San'an ndi Dalian Lumei adayang'ana kwambiri malonda awo pazitsulo zowala kwambiri potsatira zosowa za msika wa chip, zomwe zikuyendetsa mwachindunji kukula kwachangu kwa kupanga chip chowala kwambiri.Kwa kanthawi, makampani opanga zida zapakhomo za LED ayambitsa chitukuko, ndipo tchipisi zowala kwambiri zakhala zida zazikulu zoyendetsera makampani opanga zida za LED.Mu 2016, kutulutsa kwa tchipisi ta LED m'dziko langa kudafika 30,93 biliyoni, ndipo mtengo wake unafika pa 1.19 biliyoni.

Ndi kuwonjezeka kosalekeza kwa mabizinesi opanga tchipisi ta LED, kukula kwa mtengo wotulutsa chip wa LED kwakhala kokulirapo kuposa ulalo wapaketi, zomwe zimapangitsa kuti chiwonjezeko chopitilira chiwonjezeko chamtengo wamakampani a LED mdziko langa, kuchokera pa 5.4% mu 2012 mpaka 2016. 11.3%.Zitha kuwoneka kuti makampani a LED akudziko langa akuyenda kuchokera kumunsi mpaka kumapeto kwapamwamba, ndipo akupita kumalo okwera mtengo owonjezera komanso maulalo amtengo wapatali kwambiri.
