4, ukuvikelwa kwemvelo nokonga amandla kungamandla aqhubayo
Ukukhanya kokudoba kwe-LEDisidingo semakethe siqhutshwa ukuvikelwa kwemvelo kanye nezindleko zokudoba, ngosizo lwezibonelelo zikaphethiloli zabadobi ezincishiswa unyaka nonyaka, umthombo wokukhanya we-semiconductor wezimpawu zokuvikela imvelo ezonga amandla kanye nomklamo wekhwalithi yokukhanya kwe-LED kuyizinzuzo ezivelele zesibani sezinhlanzi ze-LED, inhlanzi ye-LED. Imakethe yezibani ikakhulukazi ekukhiqizeni nasekusebenzeni ukonga amandla kokushintshwa;Njengamanje, inqubomgomo yaseShayina yokuxhaswa kukaphethiloli ayizange ibonakale ekukhuthazeni amalambu okudoba ama-LED.
Kusukela kudatha yokuhlola yase-Taiwan Chenggong University, kungabonakala ukuthi isilinganiso sesibani sezinhlanzi ekusetshenzisweni kukaphethiloli simi kanje:
Ukuhlaziywa kokusetshenziswa kukaphethiloli kwemikhumbi yokudoba ngamanethi: amandla ezikebhe zasolwandle angu-24%, izibani zokudoba nemishini yokudoba 66%, okokuqandisa okungu-8%, okunye u-2%.
Ukuhlaziywa kokusetshenziswa kukaphethiloli kwemikhumbi yokudoba ngezinduku: amandla ezikebhe zasolwandle angu-19%, amalambu okudoba kanye nempahla yokudoba ama-78%, amanye ama-3%.
Ukuhlaziywa kokusetshenziswa kukaphethiloli emikhunjini yokudoba ekwindla/yokudoba izingwane: amandla ezikebhe zasolwandle angu-45%, amalambu okudoba nempahla yokudoba ama-32%, izinto zokuqandisa ama-22%, enye i-1%.
Ngokusho kokuhlaziywa kwedatha yezibalo, okwamanje, izindleko zikaphethiloli zemikhumbi yokudoba eShayina zibalelwa ku-50% ~ 60% wezindleko zokudoba, ngaphandle kwamaholo abasebenzi, ukunakekelwa kwemikhumbi yokudoba, ukwengeza iqhwa, ukwengeza amanzi, ukudla kanye nezindleko ezihlukahlukene, njll. , imikhumbi eminingi yokudoba ayinalo ithemba ngenzuzo yayo;Ukukhanya kokudoba kwe-LED kusekelwe ngenjongo yokunciphisa ukusetshenziswa kwamandla okudoba, kunzima ukuvuselela isifiso sokuthenga, ukonga ukusetshenziswa kukaphethiloli akunamdlandla ngomnikazi womkhumbi, ukukhiqizwa okwandayo kuhilela isidingo esibalulekile sabadobi sokushintshwa, nokonga amandla. ikakhulu ikhombisa inqubomgomo kahulumeni.
Ukuhlolwa kwesibani sezinhlanzi ze-LED kugxile ekongeni uphethiloli, ukungazinaki izinzuzo zokwenyuka kwesivuno ezilethwa ubuningi bokukhanya kanye nekhwalithi yokukhanya, okuyisici esiyinhloko sokuthi ukushintshwa kwesibani sezinhlanzi ze-LED kunzima ukwamukelwa emakethe;Ukudayiswa kwezibani zokudoba ze-LED ukuthi abadobi bangakwazi yini ukwandisa ukukhiqiza futhi bathole ukusebenza kahle kokudoba kanye nezinzuzo ngemva kokushintshwa, le nzuzo izobhekana ngempumelelo nezindleko zokuthengaI-LED yokudoba ngaphansi kwamanzi ukukhanya, futhi umklamo womkhiqizo ongawunaki umphumela wokukhiqiza okhulayo kunzima ukuthola amandla okuthenga abadobi.
Ngokusho kwedatha ekhona ekhaya nakwamanye amazwe, ngaphansi kwesisekelo sokuqinisekisa ukwanda kokukhiqizwa, ukonga amandla okusetshenziswa kwamandla okudoba cishe ama-45% kuyinkomba enengqondo (idatha ibalwa ngomthombo omuhle wokukhanya oqinile oqinile wokucwaninga).
Sikholelwa ukuthi umqondo wokuklama wemikhiqizo yezibani zezinhlanzi ze-LED kufanele uqale ucabange ukuthi ungathuthukisa ukukhiqizwa okukhona kokubamba, uthuthukise ukusebenza kahle kokudoba emjikelezweni wokudoba, awukwazi nje ngenjongo yokonga amandla, uma ungakwazi ukusungula ekukhiqizeni nasekukhiqizeni. ukonga ugesi, izinga lokuqedwa kwamabhizinisi eminyakeni embalwa ezayo lizoba phezulu kakhulu.
I-5, isigaba sobuchwepheshe bokukhanya kwezinhlanzi ze-LED
Inhloso yobuchwepheshe yokuqoqa izibani zezinhlanzi ukufeza i-phototaxis enhle ye-fish induction induction ukuze kwandiswe ukubanjwa, okubizwa ngokuthi i-phototaxis, ibhekisela ezicini zezilwane ekuvuseleleni imisebe yokukhanya yokunyakaza okuqondile.Ukunyakaza okuqondisayo okuya emthonjeni wokukhanya kubizwa ngokuthi "i-phototaxis eqondile", futhi ukunyakaza okuqondile kude nomthombo wokukhanya kubizwa ngokuthi "i-phototaxis engalungile".
Kunenani elincane lokusabela (inani eliwumkhawulo) lokuziphatha kwezinhlanzi ekuphenduleni emisebeni ekhanyayo yezinhlanzi zasolwandle ezinomsebenzi obonakalayo, futhi isilinganiso esiyisisekelo senani lomkhawulo sinqunywa amathuba esikhathi sokubhukuda sezinhlanzi ukusuka endaweni emnyama kuya endaweni ekhanyayo.Kodwa-ke, ucwaningo lwamanje lwezemfundo lusebenzisa i-metroloji yombono okhanyayo wamehlo omuntu, ezoveza inkinga yokuqondisa kocwaningo lwemishini ebangelwa ukukhanya.
Ukwengeza, ngenxa yezinyathelo ezihlukene zomzimba zokuphendula kwezinhlobo zezinhlanzi ezahlukene, ukuthatha inani lokukhanya njengesibonelo, ucwaningo lwamanje lukholelwa ukuthi inani elibalulekile lamaseli e-cone wezinhlanzi ngu-1-0.01Lx, futhi lamaseli ekholomu ngu-0.0001 -0.00001Lx, ezinye izinhlanzi zizoba ngaphansi, iyunithi yokukhanyisa iwukuveza ukukhanya okukhanyayo okujwayelekile ngemitha yesikwele ngomzuzwana, ukusetshenziswa kwalesi yunithi ukuveza inani lokukhanya ku-lens yeso lenhlanzi kunzima ngempela, kufanele qaphela ukuthi ukukalwa kwevelu yokukhanya kuphutha lokulinganisa indawo yokukhanya okuphansi sikhulu kakhulu.
Ake sithi umumo we-spectral welambu lokuqoqa uboniswa emfanekisweni:
Ngokwevelu yomkhawulo wamaseli ekholomu yeso lezinhlanzi ngu-0.00001Lx, inombolo ehambisanayo ye-quantum yokukhanya ingabalwa nge-XD factor yefomu le-spectral, okungukuthi, amandla emisebe yezithombe eziyizigidi eziyizinkulungwane ezingu-1 endaweni ye-micron yesikwele esingu-1.Kusukela kulelivelu lokuguqulwa, kungabonakala ukuthi akhona ngempela amandla e-photon anele ukuze ashukumise amaseli ekholomu yeso lezinhlanzi ukuze akhiqize ukuvuselela.Eqinisweni, umkhawulo wale mpendulo ungaba ngaphansi ngisho nangaphezulu, futhi nge-quantum metric ekhanyayo, singakwazi ukusungula ukuhlobana okuqondile kobuningi nokuhlaziywa kwe-cytological.
Iyunithi ye-quantum ekhanyayo ye-spectrum ingasetshenziswa ukuhlaziya ngokunembile inani lenani lemisebe yokukhanya, futhi ngesikhathi esifanayo iguqule umqondo wamanje wevolumu nebanga lemisebe yokukhanya emanzini olwandle ngokusekelwe enanini lokukhanya, futhi kusungulwe impendulo ebonakalayo yemisebe yokukhanya kanye neso lenhlanzi kuthiyori yocwaningo enengqondo yokudluliswa kwamandla.
Ukusabela kwenhlanzi emisebeni ekhanyayo kudinga ukuhlukanisa phakathi kokusabela okubukwayo nokusabela kokunyakaza, futhi impendulo yokunyakaza ifanele isifunda lapho inkambu yemisebe yokukhanya ifana ngokuqhathaniswa.Njengoba ukumelwa kwe-quantum ekhanyayo akudingi isiqondiso esithile, kulula ukwenza imodeli nokubala ukungena kweso lezinhlanzi ezichazwe inkambu ye-quantum yokukhanya emanzini olwandle.
Ukuzivumelanisa nezimo zezinhlanzi emisebeni yokukhanya emisebeni, ngenxa yokuthi imisebe ekhanyayo emanzini olwandle ikhishwa ku-gradient, inhlanzi ye-phototactic izohamba ebangeni eliguquguqukayo lemisebe yokukhanya, i-gradient ngayinye ichazwa yi-uniform light quantum field izoba nenjongo, phela, inani lokukhanyisa liqondisa.
Ucwaningo luye lwabonisa ukuthi izinhlanzi eziningi zinokuzwela kokusabela kumaza ahlukene, futhi umehluko ekuphenduleni kwe-spectral phakathi kwezinhlanzi ezincane nezinhlanzi ezindala awuphezulu, kodwa izinhlanzi eziningi zinezinkinga zokuqaphela ubude be-wavelength (ezifana nokungaboni umbala womuntu).Ngokombono wendlela yokusabela ye-spectral yamangqamuzana abukwayo, uhlobo lwe-spectral oluphezulu lwezinhlobo ezimbili zemisebe yokukhanya ye-monochromatic luphakeme kunomphumela we-spectral we-wavelength eyodwa.
Ukusabela kwezinhlanzi zasolwandle kubude begagasi bemisebe yokukhanya cishe kungama-460-560nm, okuphakeme ezinhlanzini zasemanzini ahlanzekile, futhi ukusabela kwamehlo ezinhlanzi ebangeni le-wavelength kuhlobene nemvelo yokuziphendukela kwemvelo.Ngokombono wobubanzi bemisebe ye-spectral, ibhande le-spectral lalolu bubanzi linebanga lemisebe elide kunawo wonke emanzini olwandle, futhi liwububanzi be-wavelength yokuphendula kwamehlo ezinhlanzi.Umshini unengqondo ngokwengeziwe ukuchaza ngobuchwepheshe be-spectral.
Esimeni semisebe yokukhanya engemuva ezungezile, i-phototaxis yezinhlanzi iyancishiswa, ngakho-ke kuyadingeka ukwandisa inani lokukhanya lomthombo wokukhanya noma ulungise ububanzi be-wavelength ukuze kuthuthukiswe i-inductance.Lesi senzakalo sihambisana nendlela yokubuka ukuthi i-superposition two wavelengths yokukhanya ingaphezu kwe-wavelength eyodwa, futhi ingasetshenziswa ukuchaza lesi senzakalo esidingekayo ukuqinisa inani lokukhanya eliqoqwe izinhlanzi ngaphansi kokukhanya kwenyanga.Lezi zifundo ziseyisigaba sobuchwepheshe be-spectral be-wavelength kanye nefomu le-spectral.
Ubuchwepheshe be-spectroscopy yesibani sezinhlanzi budinga ukuhlanganisa i-geometric optics kanye nendlela yokusabalalisa yama-photon asakazwa ngemidiya ehlukene.Kusukela ekuhlaziyweni kokuhlola, kungabonakala ukuthi isisho sokugcina siyifomu le-spectral kanye ne-wavelength, engahlangene nemingcele yokukhanyisa.
Ngaphezu kwalokho, kubhendi ye-UVR, ukuvezwa kwalolu banga lwe-wavelength akukwazi ukuchazwa ngenxa yemingcele yokukhanya, njengendaba yokukhanya okuyiziro, kodwa incazelo ehambisanayo ingatholakala kumasu okubonwayo.
Kubaluleke kakhulu ukutadisha i-phototaxis yezinhlanzi kanye neyunithi yokulinganisa ngokomzimba efanele yemisebe yokukhanya yesibani sokudoba.
Ingqikithi yobuchwepheshe be-spectrum ukutadisha umphumela we-spectral shape yeso lezinhlanzi kanye nokuphendula okubonakalayo kubude be-wavelength, lezi zifundo zihlobene nokuphendula okunemibandela nokuphendula okungenayo imibandela, ngaphandle kocwaningo oluyisisekelo, amabhizinisi awakwazi ukukhiqiza okuhle. ukusebenza kwesibani sezinhlanzi ze-LED.
6, kudingeka babheke imisebe ukukhanya esweni inhlanzi
I-lens yeso lomuntu i-convex lens, kanti ilensi yeso lenhlanzi iyindilinga.I-lens eyindilinga ingakhuphula inani lama-photon afakwe esweni lenhlanzi, futhi indawo yokubuka yeso lenhlanzi icishe ibe ngama-degree angu-15 amakhulu kuneso lomuntu.Ngenxa yokuthi i-lens eyindilinga ayikwazi ukulungiswa, izinhlanzi azikwazi ukubona izinto ezikude, ezihambisana nokusabela kokunyakaza kwe-phototropism.
Kukhona umehluko phakathi kwe-spectrum yalokhu okungenhla kanye nokukhanya okungaphansi kwamanzi, okubangela ukuziphatha kokuphendula kwezinhlobo zezinhlanzi ezihlukahlukene, okuwumphumela wokuphendula kweso lezinhlanzi ku-spectrum.
Isikhathi sokuhlanganisa kanye nesikhathi sokuhlala kwezinhlanzi ezihlukene endaweni yemisebe yokukhanya zihlukile, futhi imodi yokunyakaza endaweni yemisebe yokukhanya nayo ihlukile, okuwukusabela kokuziphatha kwezinhlanzi emisebeni yokukhanya.
Izinhlanzi zinempendulo ebonakalayo ku-UVR, engafundwanga kahle.
Izinhlanzi aziphenduli nje kuphela emisebeni ekhanyayo, kodwa futhi nomsindo, iphunga, amandla kazibuthe, izinga lokushisa, usawoti kanye ne-turbidity, isimo sezulu, inkathi, indawo yolwandle, imini nobusuku, njll., okungukuthi, nakuba i-spectroscopy ye-fish-lamp iyisici esiyinhloko. .Kodwa-ke, impendulo yezinhlanzi emisebeni ye-spectral akuyona ingxenye eyodwa yezobuchwepheshe, ngakho-ke kuyadingeka ukucabangela ngokucophelela ekutadisheni kobuchwepheshe be-spectral yesibani sezinhlanzi.
