Amateka yambere yo kumurika LED kumurika no gukora neza

Mu 2006, CREE yatangaje ko hashyizwe ahagaragara LED nshya yera yera, “XP.G ”, yashyizeho inyandiko nshya muburyo bwo kumurika no kumurika.Iyo ikinyabiziga cyo gutwara ari mA 350, flux yamashanyarazi igera kuri 139 lm, kandi imikorere yumucyo ni 1 kugeza kuri lm / W.Umucyo no kumurika biri hejuru ya 37% na 53% hejuru ya Cree yaka cyane XR.ELED, ibyo bita "inganda zimurika kandi zikora neza LED".

Muri 2007, Nichia yasohoye ubwoko bushya bwa LED.Ibicuruzwa byubushakashatsi bifite urumuri rwinshi rugera kuri m 145 ukurikije imiterere yimbere ya mA 350, imikorere yumucyo igera kuri 134 lm / w, chip ifite ubunini bwa m 1㎡, n'ubushyuhe bw'amabara ya 4 988K (mugihe cya Ir = 20 mA), Imikorere yumucyo ni hejuru ya 1 69 lm / W).

Mu 2007, isosiyete y'Abanyamerika CREE yakuze inshuro ebyiri kuri sisitemu ya SIC, kandi ibikoresho byakozwe nabyo byari byiza cyane.SiC substrate irashobora guhimba electrode yicyuma ya LED ishingiye kuri Gabl munsi ya substrate, kandi ikigezweho gishobora gutembera mu buryo buhagaritse binyuze mumashanyarazi mato mato, nayo ashyiraho urufatiro rwo guteza imbere ibindi bikoresho bya optoelectronic.

Muri uwo mwaka, Nichia yasohoye igisekuru kizaza cya LED zifite ingufu nyinshi.Umucyo utemba wa mA 350 winjiza ni 145lm, naho urumuri ni 134lm / W.Impamvu yo gukora cyane ya LED yera ni ukumenya neza imikorere ya chip yubururu LED yakoreshejwe.Iyo LED yubururu itwarwa na mA 350, ingufu za optique ni 651mW, uburebure bwumuraba ni 444nm, ubushobozi bwa kwant bwo hanze ni 66.5%, naho WPE ni 60.3%.

Muri uwo mwaka, Nichia yashyize mu bikorwa LED yera kandi ikora neza ya lm / W.Imikorere yiyi LED yerekana urwego rwo hejuru muruganda muricyo gihe, kandi ubwoko bufite icyerekezo cya 20 mA ni 1001m / W.

Mu ntangiriro za 2009, CREE yatangaje ko imaze kugera ku mucyo wa 161 lm / W n'ubushyuhe bw'amabara ya 4 689K.Ibipimo bisanzwe byipimisha kuri LED bikorerwa mubushyuhe bwicyumba hamwe na moteri ya mA 350.

Mu mpera za 2009, CREE yatangaje ko urumuri rwera rwera rufite ingufu nyinshi LED rumurika rumaze kugera kuri 1 86 lm / W.Ibisubizo by'ibizamini bya CREE byerekana ko iyo ubushyuhe bw'amabara bufitanye isano ari 4577K, LED irashobora gutanga umusaruro wa 1971m.Ikizamini gikorerwa ahantu hasanzwe hapimwa hamwe na drake ya mA 350 mubushyuhe bwicyumba.

Mu ntangiriro za 2009, ukurikije ibyavuye muri laboratoire ya Nichia, imikorere ya LED yongerewe igera kuri 2491 W irwanya mA 20.Nyamara, kubijyanye na mA 350 isanzwe ikoreshwa munganda za LED, imikorere yumucyo yagabanutse igera kuri 1451 ihanganye na W, ibyo bikaba byakuruye inganda.

Muri 2011, abashakashatsi ba R&D ba Osram batezimbere rwose ikoranabuhanga ryose rijyanye no gukora LED.Mu bizamini bya laboratoire, LED zera zimaze gutunganywa zerekana urumuri rwisosiyete hamwe nibikorwa byerekana neza.Muburyo busanzwe bwimikorere ya mA 350, urumuri rwa LED rushobora kugera kuri 1 55 lm, kandi urumuri rukaba ruri hejuru ya 1 36 lm / w.Itara ryera LED prototype ikoresha m 1㎡chip, ubushyuhe bwamabara yumucyo wasohotse ni 5000K, naho umuhuzabikorwa wa chromaticity ni 0.349 / 0.393 (cx / cy).

Muri 2011, CREE yatangaje ko urumuri rwera rwa LED rwera rwarenze 231lm / W.Isosiyete yakoresheje igice kimwe-module, kandi yapimye LED yera yera ya 23llm / W ku bushyuhe bwamabara ya 450OK hamwe nubushyuhe busanzwe bwicyumba cya 350mA.Kugeza ubu, ibipimo bitandukanye bya LED biracyari mu majyambere ahoraho.Hamwe no kwagura imirima yo gusaba, ibisabwa kumatara ya LED bigenda bitandukana buhoro buhoro.
