Cabanga nge-Shanghai: Ungayithola kanjani inhlanganisela ephelele yezibalo ze-LED, i-physics, nokukhanyisa?

[umbhalo / Ubunjiniyela LED Yue Motte], 'UGenesise,' wabhala, ngosuku lokuqala, uNkulunkulu wathi, Makube khona ukukhanya futhi kwaba khona ukukhanya. i-backpfrontp nje ibe yisisekelo sazo zonke izinto ezikhona. Kusukela ekukhanyeni kwemvelo kuye emlilweni, kuya ekukhanyeni kwenkundla yanamuhla, ukukhanya kwesintu okungapheli. Ukukhanya kwe-LED ngenxa yemvelo eyingqayizivele yendawo yohlelo lokusebenza kabanzi, ikakhulukazi ezinhlelweni zokusebenza ezingenasithunzi, kunezinzuzo eziningi eziyingqayizivele. i-backpfrontp Kuyaqondakala ukuthi ukusetshenziswa kwesibani esikhanyayo se-LED esingenathunzi, indawo eguquguqukayo engenasithunzi efaneleke kakhulu izidingo ezihlukene kunokuhlinzwa kwendawo egxilile. Kodwa-ke, ngenxa yendawo eguquguqukayo enqubweni yokulungisa kufanele ihlangabezane nezimfuneko zezidingo zokusabalalisa ukukhanya kokukhanya, ukufana kokukhanya, okudinga idigri engenathunzi kanye nezimfuneko zokujula kokukhanya, okwenza ukuhlaziya okubonakalayo okungenathunzi okungenathunzi kube nzima kakhulu. Ingabe kungenzeka ukwenza i-backpfrontp yendawo ihlakaniphe? ukukhiqiza ushintsho ngokuvumelana nezidingo zokukhanyisa, indawo? Shanghai ucabange kabili wasikisela ukuthi uma kukhona umsebenzi wezibalo kungenziwa belingisa LED inkundla ukukhanya ukukhanya, futhi usethe izimpikiswano zayo njengoba umsebenzi indawo kanye nosayizi indawo, khona-ke Ekubhekaneni noshintsho kuyoba indawo elula kakhulu. Ngemva kwe-backpbackpfrontp imizamo eminingi yocwaningo i-Shanghai icabanga kabili ithole ukuthi umsebenzi we-Gaussian njengomsebenzi wokukhanyisa kwe-LED, ekubhekaneni nezinguquko endaweni kunezinzuzo ezithile. Ingabe sisebenzisa ukuqinisekiswa okusebenzayo nokuhlola kwamandla aphezulu ukukhanya kwendawo yokukhanya yezikhukhula ze-LED Gaussian fit, imiphumela iqinisekise ukuthi ukuchezuka okujwayelekile kukonke kuncane kakhulu, kungaphansi kuka-0.01. Isizinda esisebenzayo somqondisi wezobuchwepheshe we-Shanghai Academy Shikang cabanga ukumelwa. I-backpfrontp yeselula Nokho, umsebenzi we-Gaussian uyimodeli yezibalo, sebenzisa umsebenzi we-Gaussian ukukhanya okungenathunzi ukuze uhlaziye, okunzima kakhulu ukuthi uhlobo lomsebenzi we-Gaussian kufanele lufakwe kabusha kulo, okuwububanzi bendawo, indawo yebala, indawo eguquguqukayo lapho ivolumu, ukugcwala kukhomba le mingcele kumsebenzi ozofingqwa. Ngesikhathi esifanayo, lo msebenzi uwukuhlangabezana nezinga kazwelonke ezingenasithunzi. Kubonakala sengathi ngenkathi kuhlangatshezwana nobunzima, kodwa ngemva kokuhlolwa okuningana nezinguquko ekugcineni zithole uhlobo oluthile lomsebenzi. U-backpfrontp Shikang utshele 'i-Engineering 1000W LED flood light', ingahlaziywa ngaphandle kokukhanya kweminye imithombo yokukhanya kwe-LED noma ngokukhanya, kodwa kude kakhulu nesibani esikhanyisa isimiso se-Gaussian. Kufanele kushiwo, ingasetshenziswa kwezinye izindawo, kodwa ngendlela yokusebenza kungase kube izinguquko ezithile ezindabeni ezithile. Uthe sisebenzisa ukuhlaziya komsebenzi wokusabalalisa kwe-Gaussian kwezinto zokukhanyisa, kodwa futhi kuphumelele. i-backpfrontp imodeli yokusebenza yezibalo eminingi, ngaphezu komsebenzi we-Gaussian, i-Shikang ithimba layo locwaningo nentuthuko likholelwa ukuthi ucwaningo olusetshenziselwa ukuchaza umsebenzi wokukhanyisa ukukhanya kwe-LED bay kulokhu, i-polynomial, umsebenzi we-Lorentz, umsebenzi we-Gaussian, imisebenzi ye-Viogt, nokunye. yizinto zabo zokucatshangelwa kanye nocwaningo. i-backpbackpfrontp Uma ufuna ukuqonda kahle uhlobo lokukhanyisa kwe-LED, uma ufuna ukuthuthukisa izinga lakho lokuklama, uma ufuna ukuqhubeka nokuba nemibono emisha evelayo, khona-ke kufanele ubambe ngokuqinile imithetho ye-physics. Ngokombono we-Shikang, i-optical design ithi ijulile kakhulu, empeleni, ibeka ngokucacile, iwumthetho obaluleke kakhulu wenyama: umthetho wokuphikisa (kuhlanganise nomthetho wokucabangela), yonke imiklamo ye-optical itholakala emthethweni wokuphikisa. Ukuhlaziywa kwezibalo kunemithetho ye-physics, kungumqondo wokuthi okuthile okuyisisekelo, ukuhlaziywa kwezibalo kuyithuluzi, kodwa futhi ukuhlaziya okuthuthuke kakhulu. Eqinisweni, ucwaningo mayelana nokukhanyisa emigwaqweni ye-LED uma selukhuphukele esimweni sokuhlaziywa kwezibalo zenkinga, khona-ke luzoba lula futhi lufinyelele indawo yonke. Ukuhlaziywa kwemvelo yenkinga ukuthi imibuzo yocwaningo kufanele icatshangelwe, kodwa ngaphezu kokuhlaziywa kwemithetho yemvelo, kufanele futhi uzame ukucabangela inkinga evela kwizibalo, okuzokwenza kube lula ukuhlaziya izinkinga, ngezinye izikhathi ngisho ezingalindelekile. ukumangala. Lapho i-Shanghai icabanga kabili ocwaningweni ukuze ichaze umsebenzi we-Gaussian ukukhanya kwe-LED, izovuna isimanga: ukugcwala okutholwe kunenani elifanele, ngokuvumelana nezindinganiso ezingenathunzi, ukugcwaliswa kwe-saturation akukukhudlwana kungcono, ngohlu oluthile indawo eguquguqukayo kanye nobubanzi bokulingana, inani elikhulu likhona ukugcwaliswa kwesikhala, okungukuthi, ukuma kwebala okungcono kakhulu, ukuze ngalesi sikhathi ezinhlobonhlobo zobukhulu bamabala kube nokufana okungcono. Futhi inqobo nje uma i-engeli ye-beam ukushintsha imingcele yayo, kanye nendawo yebala, kungaba lula kakhulu ukuchaza ukuqina kwendwangu yesikwele yesibani. i-backpbackpfrontp ineqembu elingaphezu kuka-400 R \u0026 D e-Shanghai licabanga kabili, liyaqhubeka nokuzama ukusebenzisa izinkulumo zezibalo ukuchaza umsebenzi wokusabalalisa isikwele sokukhanya kwe-LED; umsebenzi we-multivariate ngendlela efanelekile yokuchaza umsebenzi wokusabalalisa i-coefficient yokukhanya; ukuguqulwa kwe-matrix kuqedile ukuguqulwa kwesikhala sombala we-LED esilinganisiwe; umthetho ukongiwa kwamandla we-non-imaging optical design nokunye. Ngokombono kaShikang, kunezindawo eziningi lapho ungabeka khona imithetho ekhona ye-physics, izibalo ezisetshenziswa ekukhanyeni. i-backpfrontp kubesilisa abathathu \u0026 middot; I-Aurora Lighting Academy yasungulwa emcimbini, iPhini Lomphathi Jikelele wenkampani u-陈松辉 uthe, ukukhanya kwe-LED kudinga ukuhlanganiswa nabanye ochwepheshe, ukuze kuzuzwe intuthuko engcono. U-Shikang naye unombono ofanayo, ukholelwa ukuthi, ukukhanya kwe-LED akukwazi ukuchazwa nje njengokubukeka okuhle, kodwa kunalokho kusukela emgqeni onokulinganisa, ukuvumelana, ukulula nokunengqondo ukucabangela lezi zakhiwo ezine zihle. Ngakolunye uhlangothi, umklamo, umkhiqizo, kufanele ube namandla, kukhona ukubukeka kwe-United States, kukhona umnyombo womzimba onengqondo, ukwakheka kwezibalo ngqo. i-backpfrontp uma singakwazi izibalo, i-physics, ukukhanyisa kuhlanganiswe ngokuphelele, akukuhle yini? UShikang uthe ekugcineni, iphinde inikeze imboni yezibani ze-LED, bese ijova umoya ohlanzekile.
