Umthombo wokukhanya wephoyinti le-LED wuhlobo olusha lokukhanya kokuhlobisa, okuyisengezo kumthombo wokukhanya omugqa kanye nokukhanyisa kwezikhukhula.Amalambu ahlakaniphile angangena esikhundleni sokucaciswa okuthile kwezikrini zokubonisa ezifinyelela umphumela wamachashazi nezindawo ngokuxutshwa kombala we-pixel.Umthombo wokukhanya wephoyinti le-LED uthathwa njengomthombo wokukhanya we-particle point.Umthombo wokukhanya wephoyinti umqondo ongokomzimba ofingqiwe, ukuze kube lula ukutadisha izinkinga zomzimba.Njengendiza ebushelelezi, indawo enkulu, futhi akukho ukumelana nomoya, ibhekisela emthonjeni wokukhanya ophuma ngokufanayo usuka endaweni ethile uye endaweni ezungezile.
I-LED iyi-diode ekhipha ukukhanya.Isimiso sayo sokusebenza kanye nezinye izici zikagesi ziyafana nama-crystal diode avamile, kodwa izinto zekristalu ezisetshenzisiwe zihlukile.I-LED ihlanganisa ukukhanya okubonakalayo, ukukhanya okungabonakali, i-laser nezinye izinhlobo ezahlukene, futhi evamile ekuphileni ukukhanya okubonakalayo kwe-LED.Umbala okhipha ukukhanya wama-diode akhipha ukukhanya uncike ezintweni ezisetshenzisiwe.Njengamanje, kunemibala eminingi efana nophuzi, oluhlaza okotshani, obomvu, osawolintshi, oluhlaza okwesibhakabhaka, onsomi, oluhlaza okotshani, omhlophe, nombala ogcwele, futhi ingenziwa ibe yizimo ezihlukahlukene ezinjengonxande neziyingi.I-LED inezinzuzo zempilo ende, usayizi omncane nesisindo esincane, ukusetshenziswa kwamandla okuphansi (ukonga amandla), izindleko eziphansi, njll., kanye nogesi ophansi wokusebenza, ukusebenza kahle okuphezulu kokukhanya, isikhathi sokuphendula esikhanyayo esifushane kakhulu, ububanzi bokushisa bokusebenza, ukukhanya okumsulwa. umbala, kanye nesakhiwo esiqinile ( Ukumelana nokushaqeka, ukumelana nokudlidliza), ukusebenza okuzinzile nokuthembekile kanye nochungechunge lwezimpawu, kuthandwa kakhulu phakathi kwabantu.
Umzimba okhanyayo we-D useduze nomthombo wokukhanya "wephuzu", futhi ukwakheka kwesibani kulula kakhulu.Kodwa-ke, uma isetshenziswa njengesibonisi esikhulu sendawo, ukusetshenziswa kwamanje namandla kokubili kukhulu.Ama-LED ngokuvamile asetshenziselwa ukuboniswa kwamadivayisi afana nezibani zezinkomba, amashubhu edijithali, amaphaneli wokubonisa kanye namadivayisi ahlanganisayo kagesi wezithombe, futhi avame ukusetshenziselwa ukuxhumana okubonakalayo, njll., kanye nomhlobiso wezinhlaka zokwakha, amapaki okuzijabulisa, amabhodi ezikhangiso. , imigwaqo, isiteji nezinye izindawo.
Umthombo wokukhanya wephuzu le-LED, usebenzisa i-LED eyodwa njengomthombo wokukhanya, futhi ulawula indlela yokukhanya ngokusebenzisa ilensi ekhipha ukukhanya ohlangothini lwamahhala, efinyelela ukusetshenziswa kwamandla okuphansi, ububanzi obuphezulu, ukugcinwa okuphansi, nokuphila isikhathi eside.Ngemva kokuhlolwa kobuchwepheshe, ihlangabezana nezidingo zamazinga obuchwepheshe afanelekile..Uhlobo olusha lwesistimu yokubona ukukhanya kwebhakhoni olufana nelensi ekhipha ukukhanya ohlangothini lwefomu yamahhala kanye nomthombo wokukhanya wephoyinti we-LED kuwukuqamba okusha okubalulekile okutholwa idivayisi yokukhanya.
Uma kuqhathaniswa nemithombo yokukhanya yendabuko, imithombo yokukhanya yephoyinti le-LED mincane ngosayizi futhi ilula ngesisindo.Zingenziwa zibe amadivaysi ezinhlobonhlobo ezihlukahlukene ukuze kube lula ukuhlelwa nokuklama kwezibani ezihlukahlukene kanye nemishini, ngokuguquguquka okuqinile kanye nohlu olubanzi lwezinhlelo zokusebenza.Ukusebenza kahle kwemvelo.Njengoba umthombo wokukhanya we-LED awudingi ukwengeza i-mercury yensimbi ekukhiqizeni, ngemuva kokuthi i-LED ilahliwe, ngeke ibangele ukungcola kwe-mercury, futhi imfucuza yayo ingacishe isetshenziswe kabusha, engagcini nje kuphela izinsiza, kodwa futhi ivikela imvelo.Umthombo wokukhanya we-LED ophephile futhi ozinzile ungashayelwa amandla aqondile we-low-voltage, futhi amandla kagesi ajwayelekile aphakathi kuka-6~24V, ngakho ukusebenza kokuphepha kuhle kakhulu, kulungele izindawo zomphakathi.Ngaphezu kwalokho, ngaphansi kwezimo ezinhle zemvelo yangaphandle, imithombo yokukhanya ye-LED inokubola okuphansi kokukhanya nempilo ende kunemithombo yokukhanya evamile.Ngisho noma zivame ukuvulwa futhi zicishwe, impilo yazo yesevisi ngeke ithinteke.
