Uhlalutyo lobudlelwane phakathi komgangatho wezibane ze-LED kunye namandla okuqhuba

I-LED iye yaphuhliswa ngokukhawuleza kwiinkalo ezahlukeneyo zesicelo kwiminyaka yamuva nje, kuba ayinayo izinto ezinobuthi, ihambelana nokusingqongileyo, inobomi obude benkonzo, kwaye inokusebenza okuphezulu kwe-optical.Kwithiyori, ubomi benkonzo ye-LED bumalunga neeyure ezingama-100,000, kodwa kuyo yonke inkqubo yesicelo, abanye abaqulunqi bokukhanyisa izibane ze-LELED abazi ngokwaneleyo malunga nokuhanjiswa kwamandla okuqhuba okanye ukuwusebenzisa ngokungekho ngqiqweni, kwaye isiphelo sinciphisa kakhulu ubomi benkonzo yokukhanya kwe-LED. iimveliso.

Ngenxa yokwahluka kwemveliso ye-LED, ukusetyenzwa kunye nemveliso, iimpawu zamandla ombane akhoyo ngoku kunye nokusebenza kwee-LED eziveliswe ngabavelisi abohlukeneyo kunye nomenzi ofanayo kwibhetshi enye yeemveliso unomahluko omkhulu womntu ngamnye.Ukuthatha okuqhelekileyo kwe-1W ukukhanya okumhlophe okucacileyo kwe-LED kunye neemodeli njengomzekelo, ngokwendlela yokutshintsha kwe-LED yangoku kunye nombane osebenzayo, kucaciswa ngokufutshane ukuba ukukhanya okumhlophe kwe-1W kudla ngokuthatha amandla ombane osebenzayo malunga ne-3.0-3.6V.Ukuze kuqinisekiswe ubomi benkonzo ye-1WLED, umenzi we-LED jikelele uncoma ukuba i-factory yokukhanyisa isebenzise i-current ye-350mA ukuqhuba.Xa umsinga wangaphambili kumacala omabini e-LED ufikelela kwi-350mah, amandla ombane okusebenza ngaphambili kumacala omabini e-LED awayi kunyuka kakhulu, nto leyo eya kwandisa kakhulu umsinga wangaphambili we-LED ukunyusa iibhalbhu ze-LED, okwenza ubushushu be-LED bungene. umgca ohambelanayo, ngaloo ndlela ukhawuleza ukukhanya kwe-LED.umonakalo, ukunciphisa ubomi benkonzo ye-LED.Ngenxa yokungafani kombane osebenzayo we-LED kunye notshintsho lwangoku, umbane wokutshintsha oqhuba ii-LED ulawulwa ngokungqongqo.

I-LED drive switching power supply isisiseko sezibane ze-LED.Kufana nengqondo yomntu.Ukuvelisa izibane ze-LED ezikumgangatho ophezulu, indlela engapheliyo-voltage yokuqhuba ii-LED kufuneka iyekwe.
Kweli nqanaba, kwiimveliso zokukhanya ze-LED eziveliswa ngabavelisi abaninzi (ezifana nocingo olukhuselayo, iikomityi zesibane, izibane ezibonisa ukukhanya, izibane zengca, njl.), khetha izinto ezichasayo, ukunciphisa uxinzelelo lwegazi, kwaye emva koko wongeza ityhubhu yeZener diode Zener kumandla we-LED. Inkqubo yokubonelela, ukuze kukhuthazwe ii-LED's Indlela inobugwenxa obukhulu, okokuqala, ayisebenzi kakuhle, idla amandla amaninzi ombane we-electromagnetic kwi-resistor yokuhla, kwaye inokugqithisa amandla ombane asetyenziswe yi-LED, kwaye ayikwazi. ukuqhuba imisinga emikhulu.Ngenxa yokuba ukuphakama kwangoku, amandla amaninzi achithwa kwi-resistor-down-down, akukho siqinisekiso sokuba i-LED yangoku ayiyi kudlula umgangatho wayo oqhelekileyo wokusebenza.Xa uyila imveliso, ukukhetha ukunciphisa ii-voltages ezimbini ze-DC ze-LED ukuqhuba inkqubo yonikezelo lwamandla yeyona nto ilungileyo yokulahla i-chromaticity ye-LED.Khetha ukuxhathisa, indlela yokunciphisa uxinzelelo lwegazi ukutyhala i-LED, ukukhanya kwesikrini se-LED akunakuzinza.Xa amandla ombane ombane wenkqubo yonikezelo lwamandla ephantsi, i-chromaticity ye-LED imnyama, kwaye xa amandla ombane ombane wenkqubo yonikezelo lwamandla ephezulu, i-chromaticity ye-LED iphezulu, kunye ne-chromaticity ye-LED iphezulu. phezulu.Ngokwemvelo, indlela yokunciphisa uxinzelelo lwegazi iyona nzuzo enkulu yokunciphisa ixabiso leendleko.
