1. Ubururu-LED chip + ubwoko bwumuhondo-icyatsi kibisi harimo ubwoko bwa fosifori yamabara menshi

 Umuhondo-icyatsi cya fosifore igabanya igice cyaitara ry'ubururuya chip ya LED kugirango ikore Photoluminescence, naho ikindi gice cyurumuri rwubururu ruva kuri chip ya LED rwoherezwa hanze ya fosifore hanyuma igahuzwa numucyo wumuhondo-icyatsi kibisi utangwa na fosifore ahantu hatandukanye mumwanya, numutuku, icyatsi kibisi nubururu kivanze kugirango kibe urumuri rwera;Muri ubu buryo, agaciro gakomeye kerekana agaciro ka fosifore Photoluminescence ihindura imikorere, nimwe mumikorere ya kwant yo hanze, ntizarenga 75%;kandi igipimo kinini cyo gukuramo urumuri ruvuye kuri chip gishobora kugera kuri 70% gusa, kubwibyo rero, urumuri rwera rwubururu Ubururu bwo hejuru bwa LED butarenga 340 Lm / W, kandi CREE yageze kuri 303Lm / W mumyaka mike ishize.Niba ibisubizo byikizamini ari ukuri, birakwiye kwishimira.

2. Guhuza umutuku, icyatsi n'ubururuRGB LEDubwoko burimo ubwoko bwa RGBW-LED, nibindi.

 Diyode eshatu zisohora urumuri rwa R-LED (umutuku) + G-LED (icyatsi) + B- LED (ubururu) ihujwe hamwe, kandi amabara atatu yibanze yumutuku, icyatsi nubururu avangwa mu kirere kugirango bibe byera urumuri.Kugirango habeho urumuri rwera rukora neza murubu buryo, icya mbere, LED yamabara atandukanye, cyane cyane LED yicyatsi kibisi, igomba kuba isoko yumucyo mwinshi, ushobora kugaragara uhereye "kumurongo wera uringaniye" urumuri rwatsi rufite. hafi 69%.Kugeza ubu, urumuri rwiza rwa LED nubururu n umutuku rwabaye rwinshi cyane, hamwe na kwant imbere yimbere irenga 90% na 95%, ariko kwimbere kwimbere kwimbere ya LED yicyatsi iri inyuma cyane.Iki kintu cyerekana urumuri ruto rwicyatsi cya LED ishingiye kuri GaN yitwa "icyatsi kibisi."Impamvu nyamukuru nuko icyatsi kibisi kitabonye ibikoresho bya epitaxial.Ibikoresho bya fosifori arsenic nitride ikurikirana bifite imikorere mike mumuhondo-icyatsi kibisi.Ibikoresho bitukura cyangwa ubururu bikoreshwa mugukora LED icyatsi.Ukurikije imiterere yubucucike buriho, kubera ko nta gutakaza fosifore ihinduka, icyatsi LED gifite urumuri rwinshi kuruta urumuri rwatsi + fosifori.Biravugwa ko imikorere yacyo ya luminous igera kuri 291Lm / W ukurikije imiterere ya 1mA.Nyamara, igabanuka ryumucyo urumuri rwicyatsi ruterwa ningaruka ya Droop munsi nini nini irahambaye.Iyo ubucucike buriho bwiyongera, urumuri rugabanuka vuba.Kuri ubu 350mA, imikorere yumucyo ni 108Lm / W.Ukurikije imiterere ya 1A, urumuri rugabanuka.Kuri 66Lm / W.

Kuri fosifine ya III, kohereza urumuri kumurongo wicyatsi byahindutse inzitizi yibanze kuri sisitemu.Guhindura ibice bya AlInGaP kugirango bisohore urumuri rwatsi aho kuba umutuku, orange cyangwa umuhondo-bitera kugabanuka kwabatwara bidahagije bitewe nimbaraga nke ugereranije nimbaraga za sisitemu yibikoresho, ukuyemo imirasire ikora neza.

Kubwibyo, inzira yo kunoza imikorere yumucyo wa LED yicyatsi: kuruhande rumwe, wige uburyo wagabanya ingaruka za Droop mugihe cyibikoresho bya epitaxial bihari kugirango urusheho gukora neza;kumunsi wa kabiri, koresha fotoluminescence ihindura LED yubururu na fosifori yicyatsi kugirango utange urumuri rwatsi.Ubu buryo burashobora kubona urumuri rwinshi rwumucyo rwicyatsi, rushobora muburyo bwiza bwo kugera kumurongo mwinshi kuruta urumuri rwera.Ni iy'urumuri rwatsi rutari rwonyine.Nta kibazo cyo gucana.Ingaruka yicyatsi kibisi yabonetse murubu buryo irashobora kuba irenga 340 Lm / W, ariko ntizarenga 340 Lm / W nyuma yo guhuza urumuri rwera;icya gatatu, komeza ubushakashatsi ushakishe ibikoresho byawe bwite, gusa Muri ubu buryo, hariho urumuri rwicyizere ko nyuma yo kubona urumuri rwatsi ruri hejuru ya 340 Lm / w, urumuri rwera ruhujwe namabara atatu yibanze yumutuku, icyatsi kibisi nubururu LED irashobora kuba hejuru kurenza urumuri rwiza rwa chip yubururu LED yera ya 340 Lm / W.

3. Ultraviolet LEDchip + amabara atatu yibanze ya fosifore asohora urumuri 

Inenge nyamukuru yibintu bibiri byavuzwe haruguru byera LED ni ikwirakwizwa ryumwanya utangana wumucyo na chromaticity.Umucyo ultraviolet ntushobora kubonwa nijisho ryumuntu.Kubwibyo, nyuma yumucyo ultraviolet uvuye muri chip, yakirwa na fosifori eshatu yibanze yibara rya fosifora, igahinduka urumuri rwera na fotoluminescence ya fosifore, hanyuma ikoherezwa mumwanya.Ninyungu zayo nini, kimwe n'amatara gakondo ya fluorescent, ntabwo afite ibara ry'uburinganire.Nyamara, theoretical luminous efficient of ultraviolet chip-type yumucyo wera LED ntishobora kuba hejuru kurenza agaciro ka theoretical yumucyo wera wubwoko bwurumuri rwera, tutibagiwe nagaciro kerekana urumuri rwubwoko bwa RGB.Nubwo bimeze bityo ariko, binyuze mugutezimbere kwinshi-fosifori eshatu-yibanze ya fosifori ikwiranye n’umuriro wa ultraviolet urashobora kubona urumuri rwa ultraviolet urumuri rwera rwegereye cyangwa ruri hejuru ya LED ebyiri zera zera hejuru muriki cyiciro.Kwegera urumuri rwubururu ultraviolet LED, ibishoboka Ninini nini yumucyo wera LED yumurongo wo hagati hamwe nubwoko bugufi ultraviolet ntibishoboka.
