Cabanga nge-Shanghai: Ungayithola Kanjani Izibalo Ze-LED Ephelele, I-Physics, Inhlanganisela Yokukhanyisa?

[umbhalo / Ubunjiniyela LED Yue Motte], 'UGenesise,' wabhala, ngosuku lokuqala, uNkulunkulu wathi, Makube khona ukukhanya futhi kwaba khona ukukhanya.kube nje isisekelo 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? I-backpfrontp I-Shanghai icabanga kabili iphakamise ukuthi uma kukhona umsebenzi wezibalo ungalingiswa ukukhanya kokukhanya kwenkundla ye-LED, futhi imise izimpikiswano zayo njengomsebenzi wendawo kanye nosayizi webala, 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 LED', ingahlaziywa ngaphandle kokukhanya kweminye imithombo yokukhanya yezikhukhula ye-LED engu-1000W 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 lokucwaninga nentuthuko likholelwa ukuthi ucwaningo olusetshenziselwa ukuchaza umsebenzi wokukhanya kwe-LED kulokhu, i-polynomial, umsebenzi we-Lorentz, umsebenzi we-Gaussian, imisebenzi ye-Viogt, kanjalo ne- into yokucatshangelwa kanye nocwaningo. i-backpbackpfrontp Uma ufuna ukuqonda kahle uhlobo lwe-LED bay light, 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. I-backpfrontp Eqinisweni, ucwaningo mayelana nokukhanyisa kwe-LED luke lwafinyelela uhlobo lokuhlaziywa kwezibalo zenkinga, luzoba lula kakhulu 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-backpfrontp i-Shanghai icabanga kabili ocwaningweni ukuchaza umsebenzi we-Gaussian ukukhanya kokukhanya kwe-LED, izovuna isimanga: ukugcwala okutholwe kunevelu elilungile, ngokuhambisana namazinga angenathunzi, ukugcwaliswa kwesimo akukukhudlwana, ngoba uhla oluthile lwendawo 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 sokukhanya kokukhanya komgwaqo we-LED kukalwa; 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, iSekela likaMenenja Jikelele wenkampani u-Chen uthe, ukukhanya kwe-LED kudinga ukuhlanganiswa nabanye ochwepheshe, ukuze kuzuzwe ukuthuthukiswa okungcono. 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 okuqondile. i-backpfrontp uma singakwazi izibalo, i-physics, ukukhanya kuhlanganiswe ngokuphelele, akukuhle yini? UShikang uthe ekugcineni, iphinde inikeze imboni yezibani ze-LED, bese ijova umoya ohlanzekile.
