1. Indlela yokuxhuma yochungechunge

Le ndlela yokuxhuma yochungechunge inesekhethi elula, enekhanda nomsila kuxhunywe ndawonye. Okwamanje okugeleza nge-LED ngesikhathi sokusebenza kuyahambisana futhi kuhle. Njengoba i-LED iyidivayisi yohlobo lwamanje, ingaqinisekisa ngokuyisisekelo ukuthi ukushuba okukhanyayo kwe-LED ngayinye kuyahambisana. I-circuit isebenzisa lokhuIndlela yokuxhumana ye-LEDilula futhi ilungele ukuxhuma. Kodwa futhi kune-drawback ebulalayo, okungukuthi lapho enye ye-LED ihlangabezana nephutha lesifunda elivulekile, lizokwenza ukuthi yonke intambo ye-LED iphume, okuthinta ukuthembeka kokusetshenziswa. Lokhu kudinga ukuqinisekisa ukuthi ikhwalithi ye-LED ngayinye yinhle kakhulu, ngakho ukwethembeka kuzothuthukiswa ngokufanayo.

Kuyaphawuleka ukuthi uma iI-voltage ye-LED engaguqukiukunikezwa kwamandla okushayela kusetshenziselwa ukushayela i-LED, lapho i-LED eyodwa ifinyezwa, izobangela ukwanda kwamandla wesifunda. Uma inani elithile lifinyelelwa, i-LED izolimala, okuholela ekulimaleni kwawo wonke ama-LED alandelayo. Kodwa-ke, uma amandla okushayela amanje e-LED asetshenziswa njalo ukushayela i-LED, yamanje izohlala ingashintshile uma i-LED eyodwa ifinyezwa, futhi ngeke ithinte ama-LED alandelayo. Kungakhathaliseki ukuthi iyiphi indlela yokushayela, uma i-LED ivuleka, isifunda sonke ngeke sikhanyiswe.

2. Indlela yokuxhumana ehambisanayo

Isici sokuxhuma okuhambisanayo ukuthi i-LED ixhunywe ngokufana ukusuka ekhanda kuya emsileni, futhi i-voltage ethwalwa yi-LED ngayinye ngesikhathi sokusebenza iyalingana. Kodwa-ke, okwamanje kungase kungalingani ngempela, ngisho nama-LED emodeli efanayo nenqwaba yokucaciswa, ngenxa yezinto ezifana nokukhiqiza nezinqubo zokukhiqiza. Ngakho-ke, ukusatshalaliswa okungalingani kwamanje ku-LED ngayinye kungase kubangele ukuphila kwe-LED enamanje ngokweqile ukuncipha uma kuqhathaniswa namanye ama-LED, futhi ngokuhamba kwesikhathi, kuba lula ukusha. Le ndlela yokuxhumana ehambisanayo inomjikelezo olula, kodwa ukwethembeka kwayo nakho akuphakeme, ikakhulukazi uma kunama-LED amaningi, amathuba okuhluleka aphezulu.

Kuyaphawuleka ukuthi indlela yokuxhuma ehambisanayo idinga i-voltage ephansi, kodwa ngenxa yokwehla kwe-voltage eya phambili ehlukene ye-LED ngayinye, ukukhanya kwe-LED ngayinye kuhlukile. Ngaphezu kwalokho, uma i-LED eyodwa ifinyezwa, isifunda sonke sizoba sifushane, kanti amanye ama-LED ngeke asebenze kahle. Ku-LED ethile evulekile i-circuit, uma idrayivu yamanje eqhubekayo isetshenziswa, okwamanje okwabelwa ama-LED asele kuzokwanda, okungase kubangele umonakalo kuma-LED asele. Kodwa-ke, ukusebenzisa i-voltage drive njalo ngeke kuthinte ukusebenza okuvamile kwayo yonkeIsifunda se-LED.

3. Indlela yokuxhumana yeHybrid

Uxhumano lweHybrid luyinhlanganisela yochungechunge nokuxhumana okuhambisanayo. Okokuqala, ama-LED amaningana axhunywe ochungechungeni abese exhunywa ngokufana kuzo zombili iziphetho zamandla omshayeli we-LED. Ngaphansi kwesimo sokungaguquguquki okuyisisekelo kwama-LED, le ndlela yokuxhuma iqinisekisa ukuthi i-voltage yawo wonke amagatsha ilingana ngokuyisisekelo, futhi yamanje egeleza egatsheni ngalinye nayo iyafana ngokuyisisekelo.

Kuyaqapheleka ukuthi ukusetshenziswa kokuxhumeka kwe-hybrid kusetshenziswa ikakhulukazi ezimweni ezinenani elikhulu lama-LED, ngoba le ndlela iqinisekisa ukuthi amaphutha e-LED egatsheni ngalinye athinta kuphela ukukhanya okuvamile kwegatsha kakhulu, okuthuthukisa ukuthembeka uma kuqhathaniswa nochungechunge olulula. kanye nokuxhumana okufanayo. Njengamanje, izibani eziningi ze-LED ezinamandla amakhulu zivame ukusebenzisa le ndlela ukuze kuzuzwe imiphumela esebenzayo.

4. Indlela ye-Array

Ukwakheka okuyinhloko kwendlela ye-array kanje: amagatsha akhiwa ama-LED amathathu eqenjini, ngokulandelana.
