Guhuza Ibyiza: Chip Violet Chip Kurushanwa Kuri Zahabu Globes 2015 Ubwubatsi

[inyandiko / Ubwubatsi LED Yue Motte] Ubushakashatsi bwakozwe na stade LED nubushakashatsi Ikigo cy’ubushakashatsi (GGII) cyerekana ko muri 2015 umusaruro wa chip epitaxial LED uzagera kuri miliyari 14.8, byadindije iterambere, ariko icyarimwe Data nayo yerekana ko kuva igice cya mbere cyumwaka wa 2012 kugeza 2015, impuzandengo rusange yiyongereyeho gato hejuru, igabanuka ryibicuruzwa ryaragabanutse, byerekana ko inganda zinjiye mumarushanwa meza. Icyitegererezo cyibanze gifite ingufu za LED urumuri rwamazi rwashyizweho, abakora chip zitandukanye usanga muburyo bwiza bwo kubaho. Muri byo, ubuyobozi bushya butatu bwashyize ku rutonde amasosiyete ya New Harmony yifoto y’amashanyarazi (832.502), azwiho kandi kuba afite imiterere myiza ku isoko. backpfrontp ubwumvikane Optoelectronics yashinzwe mu mpera zumwaka wa 2010, imaze imyaka irenga ine yiterambere ibaye ingirakamaro kandi yingirakamaro 1000W LED y’urumuri rw’umwuzure utanga isoko yo hejuru, hamwe n’umwaka winjiza miliyoni 400 Yuan, ibicuruzwa byoherezwa mu mahanga. Isosiyete mu 2014 yatangiye guteza imbere chip-power-power-chip hamwe nitsinzi ryambere, binyuze mumasoko no gutanga ibitekerezo kubakiriya, kandi itera imbere neza. Nk’uko byatangajwe na Xu Qi backpbackpfrontp ubwumvikane bw’umushinga w’amafoto y’amashanyarazi, isosiyete ikora amashanyarazi akomeye ya violet PSS sapphire substrate ishingiye kuri chip ikura ikura epitaxial, ikoresheje amatara mashya ya siporo yubwoko bwa PSS, uburyo bwintambwe ebyiri kugirango ikemure ikibazo cyiterambere ridakabije bivamo kristu ubuziranenge Hagati aho, umuvuduko muke wubwoko butatu bwo gukura, kugirango uzamure ubuziranenge bwa kirisiti ya epitaxial layer, birashoboka kugabanya ubwinshi bwinenge, kunoza imikorere ya kwant imbere. Ku rundi ruhande, chip ikoresha igishushanyo mbonera cya zigzag, cyanonosoye amariba ya kwant ku babitwara kugira ngo ishobore kongera ingufu za electron-umwobo, Xu Qi akomeza avuga ko chip yo mu bwoko bwa N n'ubwoko bwa P yanditswe mu buryo butandukanye. gutezimbere, gukora N-ubwoko bwa P na P-layer kugirango ugabanye kwinjiza violet, birashobora kunoza imikorere yumucyo wa violet. Kugirango ubone ubuziranenge bwimbitse bwa UV LED bay foto yumucyo kandi ugerageza gufata tekiniki yo gukura kwindege idafite polar cyangwa igice cya polar polarike tekinike yo gukura kwa ba GaN bahuje ibitsina, bikuraho igice cya kwant Stark ingaruka zatewe numuriro w'amashanyarazi. backpfrontp uhereye kumasoko yitwaye, ubwumvikane bwabakiriya bayo bifotora baranyurwa cyane nibicuruzwa byumuyugubwe ufite ingufu nyinshi, bishobora kumva neza ibyo abakiriya bakeneye, hamwe nubucuruzi buhagaze, kugirango batange serivisi nyinshi zubujyanama bwa tekiniki. backpfrontp twizera ko ibicuruzwa byacu bidashobora gusa kubona ikizamini cyisoko gusa birashobora no gushimirwa nabakozi bakorana ninzobere, gutsindira Golden Globe yuyu mwaka wa LED LED yamurika kumuhanda. Harmony photoelectric Xiangdong yagaragaje.
