'Ubururu LED' butagikoreshwa? 'Violet LED' Igihe cyaje gituje

Mbere, stade yubururu LED yaka se \ u0026 mdash; \ u0026 mdash; Shuji Nakamura GaN avuye mu mahugurwa yagaragaje impinduramatwara y’ingufu, akoresheje ikoranabuhanga rya LED ryera rya LED ryera rizashira vuba cyangwa vuba. Bikaba byakuruye ikiganiro gishimishije cyinganda. backpfrontp Bamwe mu basesenguzi bagaragaje ko guhanga kwambere LED yubururu no kubona igihembo cyitiriwe Nobel muri fiziki muri 2014 Shuji Nakamura, ubu yahagaritse ubushakashatsi bwabo, wenda mu kigo cye bwite yashinze Soraa nyamukuru gusunika stade LED yijimye yerekana amatara. . Shuji Nakamura, nkabahanga mu bya siyansi ya Nobel bagomba kuba bafite amahame mbwirizamuco n’imyitwarire yabigize umwuga, kubera ko yabonye amahirwe menshi y’amatara y’umwuzure w’amashanyarazi y’amashanyarazi, azashyira ibigo nk’ubushakashatsi bishingiye ku bushakashatsi bwa LED. Umuyobozi wa ibicuruzwa bya Hongli Opto-elegitoronike Wang Gaoyang yavuze. backpfrontp uko byagenda kose, kuva kera yamenyekanye nkumuhanga, twizera kandi ko yafashe icyemezo kigomba gushingira kumyumvire ye no gutangirira kubitekerezo byubururu bwa LED bigaragara nabi, mugihe cyose hari inkunga yibitekerezo, mubisanzwe, ifite gushyira mu gaciro. Ariko \ u0026 lsquo; ubururu LED \ u0026 rsquo; oya, violet LED kandi niki Data asubiza inyuma ubururu 1000W LED amatara yumwuzure ya \ u0026 mdash; \ u0026 mdash; Shuji Nakamura backpfrontp Dukurikije imibare, ibyiza bya LED yumutuku bitewe ahanini na:? CRI yo hejuru kandi ikora neza cyane ibintu bibiri biranga. backpfrontp aho indangagaciro ndende yerekana cyane cyane muburyo bwo kubona LED yumutuku LED yera binyuze muri LED yijimye ishimisha fosifore kugirango ibone urumuri rwubururu, kandi ubukana bwumucyo bwurumuri rwubururu ntabwo buri hejuru cyane, kandi LED yumutuku irashobora gusohora uburebure bwumurongo bugaragara urumuri rwose ruri imbere, bityo rero ugereranije urwego rwo hejuru rwerekana amabara, rushobora kugera kubitekerezo kimwe nizuba ryera. Byumvikane ko ibintu nkibi byumutuku LED itukura R9 cyane cyane indangagaciro yo hejuru yerekana amabara Ra kugeza kuri 95. inyuma yinyuma na pisine Ibindi biranga LED \ u0026 mdash; \ u0026 mdash; imikorere myiza yumucyo igaragarira mu ngingo enye zikurikira: backpfrontp 1), LED yumutuku ukoresheje inganda za GaN, ni kuri GaN substrate ya GaN ishingiye kuri semiconductor yakozwe na chip ya pisine ya LED, munsi ya GaN kumatara ya tennis ya tennis ya GaN, ubuziranenge bwa kirisiti ya GaN ishingiye ku gice cya semiconductor ni ndende cyane, ku buryo amatara maremare ya LED amatara maremare yaka cyane, yihuta kandi akora neza; backpfrontp 2), chip ya LED yumutuku ishusho ya mpandeshatu isanzwe ya chip ya LED ni kare, hamwe nigereranya rya mpandeshatu LED urumuri rwa LED rwasohotse ruva kumurongo rusohora urumuri hanze yuburyo bwiza bwa chip (imikorere yo gukuramo urumuri) hejuru; backpfrontp 3), chip isanzwe yubururu LED ikorerwa kuri substrate ya safiro, GaN ishingiye kuri semiconductor hamwe na safiro itandukanye ya lattice, bityo rero ikaba ikunda kwibasirwa nudusimba twa kristaline izwi nka dislokasiyo, kandi gukoresha insimburangingo ya GaN ntaho bitandukaniye muri lattice burigihe burahari, biragoye gutandukanya inenge, ugereranije nibicuruzwa bya safiro, ubucucike bwa dislokasiyo bushobora kuba hafi 1/1000; backpfrontp 4), gukora neza ntabwo byoroshye guta (droop) ibibazo violet LED chip. Imikorere ya Luminous iragabanuka murwego rwo kunoza ubukana bw’ibyuka byongera ubwinshi bwimodoka, imikorere ya luminous iragabanuka bitewe na phenomenon, ariko kandi no kunoza umucyo wo kuba hari ikibazo gikomeye, kandi n’ubuziranenge bwa kristaline GaN ishingiye kuri GaN. ibicuruzwa, hamwe na safiro substrate ibicuruzwa ugereranije no kugabanuka kwimikorere ya luminous ntabwo byoroshye kubaho. Muri rusange, ibicuruzwa ugereranije nubutaka bwa safiro, GaN substrate yibicuruzwa byubu birashobora kwiyongera kugeza kuri 5 kugeza 10. backpfrontp yumutuku wera uhinduranya urumuri hejuru, iringaniza ikwirakwizwa, ibara ryerekana amabara ni byiza, kubungabunga ingufu, kuzamura urumuri ni ngombwa. Nubwo ibiciro biri hejuru byingaruka, ariko kandi ntibikunzwe, ariko inyungu iragaragara. Wang Gaoyang afite amahirwe yo gufata amatara ya siporo ya LED afite imyifatire myiza. backp Hongli Opto-elegitoronike yatangije amazi ya DUV LED amazi arashobora guhagarika neza imikurire ya bagiteri na Wang Gaoyang inyuma yinyuma aho Hongli Opto-elegitoronike, violet LED umurongo wibikorwa byiterambere nabyo biri mubikorwa. Hongli Opto-elegitoronike nkumusaruro wimbere mu gihugu urashobora DUV LED uruganda rupakira, ntirufite gusa umurongo wimbitse wa UV LED nini, kandi rwanashyizeho ibizamini bya laboratoire yabigize umwuga, hamwe na progaramu ya UV LED yimbitse kugirango itange abakiriya ibyiza porogaramu na verisiyo yo kugenzura, kugirango ifashe abakiriya kwemeza ko bishoboka. backpfrontp Kubwibyo, twizera kandi gukoresha ikoreshwa rya violet cyangwa ultraviolet LED ishimishije RGB ya fosifori y'amabara atatu, kugirango tubone ibara ryinshi ryerekana ikoranabuhanga rya LED ryera, imikorere ya chip yazamuwe kugeza kuri gahunda nshya yubunini mubihe, inganda zizabikora bigenda byiyongera LED Ibindi byinshi kandi bizwi cyane.
