1. Udupira tw'ubururu-LED + ubwoko bwa phosphor y'umuhondo n'icyatsi kibisi harimo ubwoko bwa phosphor y'amabara menshi

 Urusobe rw'umuhondo n'icyatsi kibisi rufata igice cy'umubumbeurumuri rw'ubururucya chip ya LED kugira ngo ikore photoluminescence, kandi igice cy'urumuri rw'ubururu ruturutse kuri chip ya LED rwoherezwa mu cyiciro cya phosphor rugahuzwa n'urumuri rw'umuhondo n'icyatsi kibisi rutangwa na phosphor ahantu hatandukanye mu mwanya, maze urumuri rutukura, icyatsi kibisi n'ubururu bivangwa kugira ngo bikore urumuri rwera; Muri ubu buryo, agaciro gakomeye cyane k'uburyo phosphor ihindura imiterere y'urumuri, ari na kimwe mu bikorwa byo hanze bya quantum, ntikizarenga 75%; kandi igipimo cyo hejuru cyo gukura urumuri muri chip gishobora kugera kuri 70% gusa, bityo muri teyori, urumuri rw'ubururu rwera Ubushobozi bwo hejuru bw'urumuri rwa LED ntibuzarenga 340 Lm/W, kandi CREE yageze kuri 303Lm/W mu myaka mike ishize. Niba ibisubizo by'ibizamini ari ukuri, birakwiye kwishimirwa.

2. Uruvange rw'umutuku, icyatsi n'ubururuLED ya RGBubwoko burimo ubwoko bwa RGBW-LED, nibindi.

 Diode eshatu zitanga urumuri za R-LED (umutuku) + G-LED (icyatsi kibisi) + B- LED (ubururu) zirahuzwa, kandi amabara atatu y'ibanze y'umutuku, icyatsi kibisi n'ubururu avangavanze mu kirere kugira ngo habeho urumuri rwera. Kugira ngo habeho urumuri rwera rukora neza muri ubu buryo, icya mbere, LED z'amabara atandukanye, cyane cyane LED z'icyatsi kibisi, zigomba kuba ari amasoko y'urumuri rukora neza cyane, ibyo bikaba bigaragara mu "rumuri rwera rufite ingufu zingana" aho urumuri rw'icyatsi kibisi rugera kuri 69%. Muri iki gihe, ubushobozi bw'urumuri rwa LED z'ubururu n'umutuku bwari hejuru cyane, aho ubushobozi bw'imbere bwa quantum burenga 90% na 95%, uko bikurikirana, ariko ubushobozi bw'imbere bwa quantum bwa LED z'icyatsi kibisi buri inyuma cyane. Iki kintu cyo kugira ubushobozi buke bw'urumuri rw'icyatsi kibisi rwa LED zishingiye kuri GaN cyitwa "icyuho cy'urumuri rw'icyatsi kibisi." Impamvu nyamukuru ni uko LED z'icyatsi kibisi zitarabona ibikoresho byazo bya epitaxial. Ibikoresho biriho bya phosphorous arsenic nitride series bifite ubushobozi buke mu buryo bw'umuhondo n'icyatsi kibisi. Ibikoresho by'umutuku cyangwa ubururu bya epitaxial bikoreshwa mu gukora LED z'icyatsi kibisi. Mu gihe cy'ubucucike bw'umuyoboro w'amashanyarazi buri hasi, kubera ko nta gutakaza phosphor, LED y'icyatsi kibisi ifite ubushobozi bwo kumurika kurusha urumuri rw'icyatsi kibisi rwo mu bwoko bwa ubururu + phosphor. Bivugwa ko ubushobozi bwayo bwo kumurika bugera kuri 291Lm/W mu gihe cy'umuyoboro wa 1mA. Ariko, kugabanuka k'ubushobozi bw'urumuri rw'icyatsi kibisi buterwa n'ingaruka za Droop mu gihe cy'umuyoboro munini ni ikintu gikomeye. Iyo ubucucike bw'umuyoboro bw'amashanyarazi bwiyongera, ubushobozi bw'urumuri bugabanuka vuba. Ku muyoboro wa 350mA, ubushobozi bw'urumuri ni 108Lm/W. Mu gihe cy'umuyoboro wa 1A, ubushobozi bw'urumuri bugabanuka. Kugera kuri 66Lm/W.

Kuri fosfini ya III, kohereza urumuri ku gice cy’icyatsi byabaye imbogamizi ikomeye ku buryo bw’ibikoresho. Guhindura imiterere ya AlInGaP kugira ngo itange urumuri rw’icyatsi aho gutanga urumuri rutukura, orange cyangwa umuhondo—bituma imbogamizi idahagije yo gutwara ibintu iterwa n’icyuho gito cy’ingufu z’ibikoresho, ibyo bikaba bikuraho gusubirana neza kw’imirasire.

Kubwibyo, uburyo bwo kunoza imikorere y'urumuri rwa LED z'icyatsi kibisi: ku ruhande rumwe, iga uburyo bwo kugabanya ingaruka za Droop mu gihe cy'ibikoresho bya epitaxial bihari kugira ngo wongere imikorere y'urumuri; ku rundi ruhande, koresha uburyo bwo guhindura urumuri rw'ubururu rwa LED z'ubururu na fosforasi z'icyatsi kibisi kugira ngo wohereze urumuri rw'icyatsi kibisi. Ubu buryo bushobora kubona urumuri rw'icyatsi kibisi rufite imikorere myiza, rushobora kugera ku bushobozi bwo hejuru bw'urumuri kurusha urumuri rw'umweru ruriho ubu. Ni urw'urumuri rw'icyatsi kibisi rudahinduka. Nta kibazo kiri mu rumuri. Ingaruka z'urumuri rw'icyatsi kibisi ziboneka muri ubu buryo zishobora kuba zirenze 340 Lm/W, ariko ntizizarenga 340 Lm/W nyuma yo guhuza urumuri rw'umweru; icya gatatu, komeza ubushakashatsi kandi ushake ibikoresho byawe bya epitaxial, gusa muri ubu buryo, hari icyizere cy'uko nyuma yo kubona urumuri rw'icyatsi kibisi ruri hejuru cyane ya 340 Lm/w, urumuri rw'umweru ruhujwe n'amabara atatu y'ibanze ya LED z'umutuku, icyatsi kibisi n'ubururu rushobora kuba ruri hejuru y'ubushobozi bw'urumuri rwa LED z'umweru z'ubururu za 340 Lm/W.

3. Itara rya Ultravioletchip + fosforasi eshatu z'amabara y'ibanze zitanga urumuri 

Inenge nyamukuru y’ubwoko bubiri bwa LED z’umweru zavuzwe haruguru ni uko urumuri n’ubukonje bitangana mu buryo bugaragara. Urumuri rwa ultraviolet ntirushobora kubonwa n’amaso y’umuntu. Kubwibyo, nyuma y’uko urumuri rwa ultraviolet ruvuye muri chip, rutwarwa na phosphor eshatu z’amabara y’ibanze zo mu gice cyo gufunga, zigahinduka urumuri rwera bitewe n’ubukonje bwa phosphor, hanyuma zigashyirwa mu mwanya. Iyi ni yo nyungu yayo ikomeye, kimwe n’amatara asanzwe ya fluorescent, nta busumbane bw’amabara y’ahantu. Ariko, ubushobozi bw’urumuri rwa ultraviolet chip-type white light LED ntibushobora kuba hejuru y’agaciro k’urumuri rw’ubururu chip-type, tutibagiwe n’agaciro k’urumuri rw’umweru rwo mu bwoko bwa RGB. Ariko, binyuze mu iterambere rya phosphor eshatu z’ibanze zikoreshwa mu gukurura urumuri rwa ultraviolet gusa, niho hashobora kubaho kubona LED z’urumuri rwa ultraviolet white light ziri hafi cyangwa zirenze LED ebyiri z’umweru zavuzwe haruguru muri iki cyiciro. Uko LED y’ubururu ultraviolet light ingana, ni ko bishoboka. Uko urumuri rw’umweru rwa ultraviolet rungana n’ubwoko bwa ultraviolet ultraviolet rungana n’urumuri rugufi ntibishoboka.
