Cinga ngeShanghai: UziPhumelela njani iMathematika ye-LED egqibeleleyo, iFiziksi, iNdibaniselwano yokuKhanya?

[umbhalo / Ubunjineli be-LED uYue Motte], 'IGenesis,' wabhala, ngosuku lokuqala, uThixo wathi, Makubekho ukukhanya kwaye kwabakho ukukhanya.kube nje isiseko sezinto zonke zikhona. Ukusuka ekukhanyeni kwendalo ukuya emlilweni, ukuya kukukhanya kwebala lanamhlanje, ukukhanya koluntu olungenasiphelo. Ukukhanya kwe-LED ngenxa yobume obukhethekileyo bomphezulu wesicelo ngokubanzi, ngakumbi kwizicelo ezingenasithunzi, kukho iingenelo ezininzi ezizodwa. I-backpfrontp Kuyaqondwa ukuba ukusetyenziswa kwesibane esikhanyayo se-LED esingenathunzi, indawo eguquguqukayo yokusebenza engenasithunzi ifaneleke ngakumbi kwiimfuno ezahlukeneyo kunotyando olusisigxina. Nangona kunjalo, ngenxa yendawo eguquguqukayo kwinkqubo yohlengahlengiso kufuneka ihlangabezane neemfuno zeemfuno zokukhanya kokukhanya, ukufana kokukhanya, kufuna isidanga esingenasithunzi kunye neemfuno zobunzulu bokukhanya, nto leyo eyenza uhlalutyo lwe-optical oluguquguqukayo olungenathunzi lube nzima ngakumbi. Ngaba kuyenzeka ukwenza indawo ye-backpfrontp ilumke? ukuvelisa utshintsho ngokweemfuno zokukhanyisa, indawo? i-backpfrontp Shanghai icinga kabini icebisa ukuba kukho umsebenzi wezibalo unokulinganiswa ukukhanya kwebala le-LED, kwaye umise iingxoxo zayo njengomsebenzi wendawo kunye nobukhulu bebala, ngoko Ekujonganeni notshintsho kuya kuba yindawo elula kakhulu. Emva kwe-backpbackpfrontp imizamo yokufunda emininzi i-Shanghai icinga kabini ukuba umsebenzi we-Gaussian njengomsebenzi wokukhanya kwe-LED, ekujonganeni notshintsho kwindawo ineenzuzo ezithile. Ngaba sisebenza kunye novavanyo lokuqinisekisa amandla aphezulu e-LED yezikhukhula zokukhanya indawo yokukhanyisa i-Gaussian fit, iziphumo ziqinisekisile ukuba umgangatho oqhelekileyo uwonke uncinci kakhulu, ungaphantsi kwe-0.01. Imvelaphi esebenzayo ye-Shanghai Academy umlawuli wezobugcisa uShikang ucinga ukumelwa. Mobile backpfrontp Nangona kunjalo, umsebenzi weGaussian yimodeli yemathematika, sebenzisa umsebenzi weGaussian ukukhanya okungenathunzi kuhlalutyo, olona lunzima kukuba uhlobo lomsebenzi weGaussian kufuneka lufakwe ngokutsha, bububanzi bendawo, indawo yendawo, indawo eguquguqukayo umthamo, indawo epheleleyo ezi parameters kumsebenzi oza kushwankathelwa. Kwangaxeshanye, lo msebenzi kukuhlangabezana nomgangatho wesizwe ongenathunzi. Kubonakala ngathi ngelixa udibana nobunzima ngakumbi, kodwa emva kweemvavanyo ezininzi kunye notshintsho ekugqibeleni lwafumana uhlobo oluthile lomsebenzi. U-backpfrontp uShikang uxelele 'i-LED yobunjineli', inokuhlalutywa ngaphandle kokukhanya kweminye imithombo yokukhanya ye-1000W ye-LED okanye ngokukhanya, kodwa kude kakhulu kwisibane esikhanyisa umgaqo we-Gaussian. Kufuneka kuthiwe, inokusetyenziswa kwezinye iindawo, kodwa ngohlobo lomsebenzi kunokubakho utshintsho kwimiba ethile. Uthe sisebenzisa uhlalutyo lomsebenzi wokusabalalisa kwe-Gaussian kwizibane zokukhanyisa, kodwa ziphumelele. i-backpfrontp imodeli yomsebenzi wezibalo ezininzi, ukongeza kumsebenzi weGaussian, iShikang yophando kunye neqela lophuhliso likholelwa ukuba uphando olusetyenziselwa ukuchaza umsebenzi wokukhanya kwe-LED kulo mba, i-polynomial, umsebenzi we-Lorentz, umsebenzi weGaussian, imisebenzi ye-Viogt, kwaye kunjalo nabo. ingqwalasela kunye nenjongo yophando. i-backpbackpfrontp Ukuba ufuna ukuqonda kakuhle uhlobo lwe-LED bay light, ukuba ufuna ukuphucula inqanaba lakho loyilo, ukuba ufuna ukuqhubeka neengcamango ezintsha ezivelayo, ngoko kufuneka ubambe ngokuqinileyo imithetho ye-physics. Ngokombono we-Shikang, i-optical design ithi inzulu kakhulu, ngokwenene, ibeka ngokucacileyo, ngumthetho obaluleke kakhulu wenyama: umthetho wokuchasa (kubandakanywa nomthetho wokubonakalisa), yonke i-optical design ifunyenwe kumthetho wokuphikisa. Uhlalutyo lwemathematika kunemithetho yefiziksi, yingqiqo yokuba into ebaluleke ngakumbi, uhlalutyo lwemathematika sisixhobo, kodwa kunye nohlalutyo oluphambili. I-backpfrontp Enyanisweni, uphando malunga nokukhanyisa kwe-LED xa sele inyukele kwimeko yohlalutyo lwemathematika yengxaki, ngoko kuya kuba lula ngakumbi kwaye jikelele. Uhlalutyo lobume bemeko yengxaki kukuba imibuzo yophando kufuneka iqwalaselwe, kodwa ukongeza kuhlalutyo lwemithetho yendalo, kufuneka kwakhona uzame ukuqwalasela ingxaki evela kwimathematika, eya kwenza kube lula ukuhlalutya iingxaki, ngamanye amaxesha nokuba kungalindelekanga. ukothuka. Xa i-backpfrontp i-Shanghai icinga kabini kuphononongo ukuchaza umsebenzi we-Gaussian itonela yokukhanya ukukhanya kwe-LED, iya kuvuna isimangaliso: ukugcwala okufunyenweyo kukho ixabiso elilelona liphezulu, ngokuhambelana nemigangatho engenasithunzi, i-saturation ayiyona inkulu ngcono, kuba Uluhlu oluthile lwamabala oguqulo kunye noluhlu olulinganayo, elona xabiso liphezulu likhona ukugcwaliseka, oko kukuthi, eyona milo yamachaphaza egqwesileyo, ukuze ngeli xesha kuluhlu lobungakanani bamabala kube nokufana okungcono. Kwaye okoko nje i-engile yomqadi ukuguqula iiparamitha zayo, kunye nesithuba sebala, kunokuba lula kakhulu ukuchaza ubunzulu belaphu lesibane sesikwere. i-backpbackpfrontp ingaphezulu kwe-400 R \u0026 D iqela e-Shanghai licinga kabini, liyaqhubeka lizama ukusebenzisa amabinzana ezibalo ukuchaza umsebenzi wokusabalalisa ukukhanya kwe-LED; umsebenzi wemultivariate onendlela efanelekileyo yokuchaza umsebenzi wokusabalalisa i-coefficient yokuqaqamba; uguqulo lwematriksi lugqityiwe Umlinganiselo wesibane sesitrato se-LED soguqulo lwendawo; umthetho wogcino amandla kuyilo non-imaging optical njalo njalo. Ngokombono weShikang, kukho iindawo ezininzi onokuthi ubeke imithetho ekhoyo ye-physics, imathematika esetyenziselwa ukukhanya. i-backpfrontp kumadoda amathathu \u0026 middot; I-Aurora Lighting Academy yasungulwa kumthendeleko, iSekela likaMphathi Jikelele wenkampani u-Chen uthe, ukukhanya kwe-LED kufuna ngakumbi kudityaniswe nezinye iingcali, ukuze kuphunyezwe uphuhliso olungcono. U-Shikang naye unombono ofanayo, ukholelwa ukuba, ukukhanya kwe-LED akunakutolikwa nje njengento ekhangelekayo, kodwa kunoko ukusuka kumgca we-symmetry, ukuvumelanisa, ukulula kunye nengqiqo ukuqwalasela ezi zakhiwo zine zihle. Ngakolunye uhlangothi, i-design, imveliso, kufuneka ibe namandla, kukho ukubonakala kwe-United States, kukho isiseko somzimba esifanelekileyo, ukuqulunqwa kwezibalo ezichanekileyo. backpfrontp ukuba singakwazi imathematika, fiziksi, ukukhanya organically kudityaniswe ngokupheleleyo, Ngaba ayisiyonto intle? UShikang uthe ekugqibeleni, inika imboni yokukhanyisa i-LED, kwaye emva koko itofe umoya omtsha.
