Kulungile, Ubuhlalu Bokukhanya Okunsomi, Kulungile

Ngo-2016, ithimba lesayensi nobuchwepheshe locwaningo kanye nentuthuko lithole imiphumela emihle ekusebenzeni kwezindleko eziphezulu zomthombo wokukhanya we-COB ohlanekezelwe. Ngokombono wenqubo yokupakisha, amabakaki asetshenziswa umthombo wokukhanya we-COB anosayizi abaningi. Inqwaba yabakaki, izinto zabo ngokuyinhloko ziyi-aluminium, futhi kukhona abakaki bethusi kanye ne-ceramic. Ngokuvamile, alukho uhlangothi. Abakaki abasetshenziswa ebuhlalu belambu be-LED edidiyelwe yi-10W, 100W, 500W kuphela kanye nabanye abakaki besikwele. Izinto ezisetshenziswayo ngokuyinhloko ziyithusi, futhi amabakaki anezinyawo ezihlangothini ezingu-2. I-LED iyidivayisi eqinile ye-semiconductor, engaguqula ngokuqondile ugesi ube ukukhanya. I-LED iwubuchwepheshe bokukhanyisa besizukulwane sesithathu ngemva kwamalambu e-incandescent namalambu e-fluorescent. Inezici zokonga amandla, ukuvikelwa kwemvelo, iphephile futhi inokwethenjelwa. Ubuhlalu bokukhanya okunsomi bubona imodeli yesibani somgwaqo ye-COB ehlanekezelwe. Idatha ye-CRI > 80 ukukhanya kwedlula 190LM/W, futhi kungakhiqizwa ngamaqoqo. Ihamba phambili embonini. Lo mkhiqizo uyisinqumo esingcono kakhulu sokukhiqiza imikhiqizo ephezulu. Njengamanje, izindawo zayo zokusebenza eziyinhloko cishe yilezi: Njengoba i-LED ingumzimba okhanyayo oyisicaba, ukukhanya kwayo kuphakeme njenge-120LM/W, ephakeme kakhulu kune-100LM/W ye-70LM/W yezibani ezivamile ze-fluorescent kanye ne-T5. izibani. Umphumela wokukhanya ophakeme. Njengoba sonke sazi, ikhwalithi yama-chips e-LED inomthelela omkhulu kukhwalithi yokupakishwa engezansi noma imikhiqizo yokugcina. Amakhasimende anezidingo eziphakeme zokungaguquguquki, ukuzinza, kanye nokubola okukhanyayo kwama-chips e-LED. U-Hua Chan ubelokhu elondoloza ukuqamba okusha okuqhubekayo kanye nokwenza kahle kobuchwepheshe bomkhiqizo, efinyelela izinga lobuchwepheshe bezinga lokuqala lamazwe ngamazwe, futhi wathola ukuqashelwa kwamakhasimende avamile embonini. I-Purple light bead monomer architecture, iqoqo lesakhiwo somlando ukukhanyisa odongeni lwangaphandle, ukukhanya nokufakelwa ngaphandle kwesakhiwo, ukukhanya kwendawo yangaphakathi, ukukhanya kwe-green landscape, ukukhanyisa ikhadi lokukhangisa, isiko lezokwelapha kanye nezinye izikhungo ezikhethekile ukukhanyisa, imigoqo, i-ballroom nezinye izindawo zokuzijabulisa zokukhanyisa umoya. , njll. Indawo kagesi ye-chip exhunywe ekuxhumekeni kwe-substrate ngebhondi yentambo esagolide ebheke phezulu, futhi indawo kagesi ye-chip yokuthela ebheke phansi ilingana nokuphendula eyangaphambili, ngakho ibizwa ngokuthi. “I-chip ehlanekezelwe ”Inqubo yokupakisha ehambisanayo ibizwa ngokuthi “Inqubo ehlanekezelwe ”. Kunezindlela ezimbili zokuthola ukukhanya kwe-LED okunamandla amakhulu: enye iwukuhlanganisa i-chip eyodwa ye-LED enamandla amakhulu, kanti enye iwukusebenzisa ukupakishwa kokuhlanganiswa kwe-multi-chip. Okwangaphambili, ngokuthuthukiswa kobuchwepheshe be-chip, usayizi uyakhula futhi ikhwalithi iyathuthukiswa, ama-LED aphezulu angafinyelelwa ngamashayeli amakhulu amanje, kodwa ngesikhathi esifanayo, azonqunywa usayizi we-chip. Lesi sakamuva sinokuguquguquka okukhulu namandla okuthuthuka. Inombolo yama-chips ingashintshwa ngokuya ngokukhanyisa okuhlukahlukene. Ngesikhathi esifanayo, inokusebenza kwezindleko eziphezulu, okwenza ukupakishwa kokuhlanganiswa kwe-LED kube enye yezinkomba ezijwayelekile zokupakishwa kwe-LED. Kusukela ngo-2009, ukuze anqamule ukuzimela kwabakhiqizi bangaphandle kulo mkhakha, u-Xionng Daxi uhole ithimba ngokusekelwa okuqinile kwe-Chinese Academy of Sciences, i-Jiangsu, i-Suzhou, nezindawo zobuchwepheshe obuphezulu, egxile ocwaningweni nasekuthuthukisweni nasekuthuthukisweni. ukwenziwa kwezimboni kwemithombo yokukhanya ye-LED ekhethekile. Ngokusho kukaR & Ubuchwepheshe bokuklama nokukhiqiza, sigxile ocwaningweni nasekuthuthukisweni nasezindleleni ezihlukene, futhi sizuze impumelelo enkulu. Ubuhlalu obukhanyayo obunsomi I-LED ehlanekezelwe igolide -wire chip -level packaging. Ngokusekelwe kubuchwepheshe be-chip ehlanekezelwe, okusekelwe ekufakweni kwefomethi ye-chip evamile, ubuchwepheshe bomugqa wokushisela wentambo yegolide buyancishiswa, kushiye kuphela ama-chips nokukhanya ngempushana ye-fluorescent nokunye ukusetshenziswa.
