Njengamanje, imithombo yokukhanya ebonakalayo efanelekile ihlanganisa isibani se-high-frequency fluorescent, isibani se-fiber optical halogen, isibani se-xenon nomthombo wokukhanya we-LED. Izinhlelo zokusebenza eziningi ziyimithombo yokukhanya eholayo. Nazi ezimbalwa ezivamileUkukhanya kwe-LEDimithombo ngokuningiliziwe.

1. Umthombo wokukhanya oyindilinga

IIsibani se-LEDubuhlalu buhlelwa ngendandatho futhi bakhe i-engeli ethile nge-eksisi emaphakathi yesiyingi. Kunama-engeli okukhanya ahlukene, imibala ehlukene kanye nezinye izinhlobo, ezingagqamisa ulwazi lwezinhlangothi ezintathu zento; Xazulula inkinga yesithunzi sokukhanyisa esinezinhlangothi eziningi; Uma kunethunzi elikhanyayo esithombeni, lingahlonywa nge-diffuser ukwenza ukukhanya kuhlakazeke ngokulinganayo. Izinhlelo zokusebenza: ukutholwa kwesici sosayizi wesikulufu, ukutholwa kohlamvu lwendawo ye-IC, ukuhlolwa kwebhodi lesifunda solder, ukukhanya kwe-microscope, njll.

2. Ukukhanya kwebha

Ubuhlalu obunama-LED buhlelwa ngamapheshana amade. Isetshenziswa kakhulu ukukhanyisela izinto nge-engeli ethile ehlangene noma emaceleni amaningi. Gqamisa izici zonqenqema zento, ezingahlanganiswa ngokukhululekile ngokuya ngesimo sangempela, futhi i-engeli ye-irradiation nebanga lokufaka linamadigri angcono enkululeko. Isebenza entweni ehloliwe enesakhiwo esikhulu. Izinhlelo zokusebenza: ukutholwa kwegebe lengxenye ye-elekthronikhi, ukutholwa kwesici se-cylinder surface, ukutholwa kwebhokisi lokupakisha lokuphrinta, ukutholwa kwe-contour yesikhwama semithi ewuketshezi, njll.

3. Umthombo wokukhanya we-coaxial

Umthombo wokukhanya ongaphezulu uklanywe nge-spectroscope. Isebenza ezindaweni ezingaphezulu ezinobunzima obuhlukene, ukubukeka okuqinile noma indawo engalingani. Ingakwazi ukubona amaphethini aqoshiwe, imifantu, imihuzuko, ukuhlukaniswa kwezindawo ezibonisa ukukhanya okuphansi nezindawo ezibonisa phezulu, futhi isuse izithunzi. Kumele kuqashelwe ukuthi umthombo wokukhanya we-coaxial unokulahlekelwa kokukhanya okuthile ngemva komklamo we-spectral, odinga ukucabangela ukukhanya, futhi awufaneleki ukukhanya kwendawo enkulu. Izinhlelo zokusebenza: ingilazi nefilimu yefilimu ikhonta nokutholwa kokuma, ukutholwa kohlamvu lwe-IC nokubeka indawo, ukungcola kwendawo eyilucwecwana kanye nokutholwa kokuklwebheka, njll.

4. Umthombo wokukhanya weDome

Ubuhlalu besibani se-LED bufakwe ngezansi ukuze bukhanyise ngendlela efanayo into ngokusebenzisa ukubonakaliswa okusabalalisayo kocwecwe olukhanyayo odongeni lwangaphakathi lwe-hemispherical. Ukukhanya okuphelele kwesithombe kufana kakhulu, okufanele ukutholwa kwensimbi, ingilazi, indawo ye-concave convex kanye nendawo ye-arc enomfanekiso oqinile. Izinhlelo zokusebenza: ukutholwa kwesikali sephaneli yensimbi, insimbi ingabonakalisa ukutholwa kwe-inkjet, ukutholwa kwentambo yegolide ye-chip, ukutholwa kokuphrinta kwengxenye ye-elekthronikhi, njll.

5. Ukukhanya kwangemuva

Ubuhlalu bokukhanya kwe-LED buhlelwa endaweni (indawo engaphansi ikhipha ukukhanya) noma ihlelwe eduze nomthombo wokukhanya (uhlangothi lukhipha ukukhanya). Ivamise ukusetshenziselwa ukugqamisa izici ze-contour yezinto futhi ifanele ukukhanya kwendawo enkulu. I-backlight ngokuvamile ibekwe phansi kwezinto. Ukuthi umshini ukulungele yini ukufakwa udinga ukucatshangelwa. Ngaphansi kokunemba kokutholwa okuphezulu, ukufana kokukhanya kungaqiniswa ukuze kuthuthukiswe ukunemba kokutholwa. Isicelo: ukulinganisa usayizi wezingxenye zemishini kanye nokukhubazeka konqenqema, ukutholwa kwezinga loketshezi lwesiphuzo kanye nokungcola, ukutholwa kokuvuza okukhanyayo kwesikrini sefoni ephathekayo, ukutholwa kwesici sokuphrinta, ukutholwa komphetho wefilimu yepulasitiki, njll.

6. Ukukhanya kwephoyinti

I-LED ekhanyayo, usayizi omncane, ukuqina okukhanyayo okuphezulu; Isetshenziswa kakhulu ne-telecentric lens. Iwumthombo wokukhanya we-coaxial ongaqondile onenkundla encane yokuthola. Izinhlelo zokusebenza: ukutholwa kwesekethe yocingo yangaphakathi kwesikrini esiyimfihlo, ukuma kwephoyinti lokumaka, ukutholwa kokuklwebheka kwendawo yengilazi, ukutholwa kokulungiswa kwe-substrate yengilazi ye-LCD, njll.

7. Ukukhanya komugqa

I-LED ekhanyayokuhlelwa, futhi ukukhanya kugxilwe yikholomu yomhlahlandlela wokukhanya. Ukukhanya kusebhandeni elikhanyayo, elivame ukusetshenziswa kumakhamera alandelanayo. Kusetshenziswa ukukhanya okuseceleni noma ukukhanya okuphansi. Umthombo wokukhanya womugqa ungaphinda usabalalise ukukhanya ngaphandle kokusebenzisa ilensi ejiyayo, ukhuphule indawo yemisebe, futhi wengeze isihlukanisi sebhili engxenyeni engaphambili ukuze uyiguqule ibe umthombo wokukhanya kwe-coaxial. Isicelo: Ukutholwa kothuli olungaphezulu kwe-LCD, ukuklwebheka kwengilazi nokutholwa kokuqhekeka kwangaphakathi, ukutholwa kokufana kwendwangu yendwangu, njll.

Ngezinhlelo zokusebenza ezithile, ukukhetha uhlelo oluhle kakhulu lokukhanyisa kusuka ezinhlelweni eziningi kuyisihluthulelo somsebenzi ozinzile wesistimu yonke yokucubungula isithombe. Ngeshwa, alukho uhlelo lokukhanyisa lomhlaba wonke olungakwazi ukuzivumelanisa nezimo ezihlukahlukene. Nokho, ngenxa yokuma okuningi nezici zemibala eminingi zemithombo yokukhanya ye-LED, sisathola izindlela ezithile zokukhetha imithombo yokukhanya ebonakalayo. Izindlela eziyinhloko yilezi:

1. Indlela yokuhlola yokubona (ukubukeka nokuhlola - okuvame ukusetshenziswa kakhulu) izama ukukhanyisela izinto ezindaweni ezihlukene ngezinhlobo ezahlukene zemithombo yokukhanya, bese ibheka izithombe ngekhamera;

2. Ukuhlaziywa kwesayensi (okusebenza kakhulu) kuhlaziya indawo yokuthwebula izithombe bese kuncoma ikhambi elingcono kakhulu.
