I-LED ithuthuke ngokushesha emikhakheni ehlukahlukene yohlelo lokusebenza eminyakeni yamuva, ngoba ayinazo izinto ezinobuthi, ihambisana nemvelo, inempilo ende yesevisi, futhi inokusebenza kahle okuphezulu kwe-optical.Ngokombono, impilo yesevisi ye-LED cishe amahora angu-100,000, kodwa kuyo yonke inqubo yokufaka isicelo, abanye abaklami bokukhanyisa i-LELED abazi ngokwanele mayelana nokunikezwa kwamandla okushintsha ukushayela kwe-LED noma ukuyisebenzisa ngokungenangqondo, futhi isiphetho sifinyeza kakhulu impilo yesevisi yokukhanyisa kwe-LED. imikhiqizo.
Ngenxa yokuhluka kokukhiqizwa kwe-LED, ukucutshungulwa nokukhiqizwa, izici zamanje nezokusebenza zamandla kagesi wama-LED akhiqizwa abakhiqizi abahlukene ngisho nomkhiqizi ofanayo eqoqweni elifanayo lemikhiqizo unomehluko omkhulu ngamunye.Ukuthatha okujwayelekile okungu-1W ukukhanya okumhlophe kwe-LED okucaciswayo namamodeli njengesibonelo, ngokuya ngomkhuba wokushintsha we-LED yamanje kanye ne-voltage esebenzayo, kuchazwa kafushane ukuthi ukukhanya okumhlophe okungu-1W ngokuvamile kusebenzisa i-voltage esebenzayo engaba ngu-3.0-3.6V.Ukuze kuqinisekiswe impilo yesevisi ye-1WLED, umkhiqizi we-LED jikelele uncoma ukuthi ifekthri yokukhanyisa isebenzise amandla amanje angu-350mA ukushayela.Uma amandla ahamba phambili nhlangothi zombili ze-LED afinyelela ku-350mah, amandla ogesi ahamba phambili ezinhlangothini zombili ze-LED ngeke anyuke kakhulu, okuzokwandisa kakhulu ukuhamba phambili kwe-LED ukuze kwandiswe ama-LED, okwenza izinga lokushisa le-LED lingene. umugqa ohambisanayo, ngaleyo ndlela kusheshiswe ukukhanya kwe-LED.umonakalo, ukunciphisa impilo yesevisi ye-LED.Ngenxa yokuhluka kwamandla kagesi we-LED kanye nezinguquko zamanje, amandla okushintsha ashayela ama-LED aphethwe ngokuqinile.
Ukunikezwa kwamandla okushintsha idrayivu ye-LED kuyisisekelo sezibani ze-LED.Kufana nobuchopho bomuntu.Ukuze wakhe izibani ze-LED ezisezingeni eliphezulu, indlela yokuguqula amandla kagesi njalo yokushayela ama-LED kufanele iyekwe.
Kulesi sigaba, emikhiqizweni yokukhanya ye-LED ekhiqizwe abakhiqizi abaningi (njengocingo oluvikelayo, izinkomishi zamalambu, amalambu okukhanya, amalambu otshani, njll.), khetha izinto eziphikisayo, zehlise umfutho wegazi, bese wengeza ishubhu leZener diode Zener emandleni e-LED. uhlelo lokuhlinzeka, ukuze kuthuthukiswe ama-LED's Indlela inobubi obukhulu, okokuqala nje, ayisebenzi kahle, idla amandla kazibuthe amaningi ku-resistor eyehlayo, futhi ingase yeqe ngisho namandla kazibuthe asetshenziswa yi-LED, futhi ayikwazi. shayela imisinga emikhulu.Ngenxa yokuthi ukuphakama kwamanje, amandla engeziwe ahlakazeka kusiphikisa esisuka phansi, asikho isiqinisekiso sokuthi i-LED yamanje ngeke idlule izinga layo elivamile lokusebenza.Lapho uklama umkhiqizo, ukukhetha ukunciphisa ama-voltage amabili e-DC e-LED ukushayela uhlelo lokuphakela amandla kuyinzuzo enkulu yokushiya i-chromaticity ye-LED.Khetha ukumelana, indlela yokwehlisa umfutho wegazi ukuze usunduze i-LED, ukukhanya kwesikrini kwe-LED akukwazi ukuzinza.Lapho i-voltage yokuphakelwa kwamandla yesistimu yokuphakelwa kwamandla iphansi, i-chromaticity ye-LED iba mnyama, futhi lapho i-voltage yokuphakela amandla yesistimu yokuphakela amandla iphezulu, i-chromaticity ye-LED iphezulu, kanye ne-chromaticity ye-LED phezulu.Ngokwemvelo, indlela yokwehlisa umfutho wegazi iyinzuzo enkulu yokwehlisa inani lezindleko.
