Ukubaluleka kokunikezwa kwamandla okushayela ezibani ze-LED
Abanye abakhiqizi bandisa inzuzo ukuze behlise izindleko ngokusebenzisa abashayeli abasezingeni eliphansi. Kufanele kube nenkinga yokuphepha engafakwanga kulo mkhiqizo ovikelekile ongaqhumisi.
Amanye amafektri, ukuze kuncishiswe izindleko zemikhiqizo, ukusetshenziswa kwe-voltage drive LED njalo, futhi kwaletha ukukhiqizwa okukhulu kokukhanya kwe-luminescence ngayinye ye-LED akuyona iyunifomu, ama-LED awakwazi ukusebenza esimweni esihle kanye nochungechunge lwezinkinga.
Umthombo wamanje oqhubekayo ushayela imodi yokushayela ye-LED enhle, ukusetshenziswa kwedrayivu yomthombo wamanje wamanje, akudingi ukuba ochungechungeni lwesekethe lokuphumayo ukumelana nomkhawulo wamanje, ukugeleza kwamanje kwe-LED akuthintwa izinguquko zamandla kagesi wangaphandle, ukushintsha kwezinga lokushisa elizungezile, kanye Ipharamitha ye-LED ehlukanisiwe, ukuze igcinwe yamanje njalo, nikeza ukudlala okugcwele ezicini ezihlukahlukene ezinhle kakhulu ze-LED.
Ukusebenzisa ukunikezwa kwamandla wamanje we-LED ukuze kunikwe amandla izibani ze-LED, ngenxa yokuthi okwamanje okugeleza ku-LED kutholwa ngokuzenzakalelayo futhi kulawulwe ngesikhathi sokusebenza kwamandla, ngakho-ke akudingeki ukhathazeke ngokuba nokugeleza okuphezulu kwamanje nge-LED ngesikhathi samandla. , futhi akudingeki ukhathazeke mayelana nokushesha kokulayisha ukunikezwa kwamandla.
Isebenzisa imodi yokushayela yamanje, ingagwema ukuguqulwa kwe-voltage ye-LED enhle futhi ibangele izinguquko zamanje, kuyilapho okwamanje njalo yenza ukukhanya kwe-LED kuzinzile, kodwa futhi kusiza imboni ye-LED luminaire ukuthi iqalise ukukhiqiza ngobuningi ukuze kuqinisekiswe ukungaguquguquki komkhiqizo, ngakho abakhiqizi abaningi baye baqaphela ngokugcwele ukubaluleka kokunikezwa kwamandla okushayela, abakhiqizi abaningi bezibani ze-LED bayilahlile imodi ye-voltage engaguquki, futhi bakhetha indlela yamanje ebiza kancane ephakeme yokushayela izibani ze-LED.
Abanye abakhiqizi bakhathazeke ngokuthi i-electrolyte capacitor ye-electrolyte board izothinta impilo yamandla, empeleni ukungaqondi kahle, isibonelo, uma ukhetha ama-degree angu-105, ukuphila kwamahora angu-8000 okushisa okuphezulu kwe-electrolyte capacitor, ngokusho kwe-electrolyte capacitor ekhona. indlela yokulinganisa impilo "konke ukuncishiswa kwamadigri angu-1 0, ukuphila okuphindwe kabili", bese kuba nempilo yokusebenza yamahora angu-16,000 endaweni engama-95-degree, impilo yokusebenza amahora angu-32,000 endaweni engama-85-degree, kanye nempilo yokusebenza Amahora angama-64,000 endaweni engama-75-degree. Uma izinga lokushisa langempela lokusebenza liphansi, impilo izoba yinde! Kuleli phuzu lokubuka, inqobo nje uma ukukhethwa kwekhwalithi ephezulu ye-electrolyte capacitor empilweni yokunikezwa kwamandla okushayela kungathinteki!
Kukhona futhi iphuzu elifanele ukuphawula kwamabhizinisi e-LED luminaire: ngoba i-LED ohlelweni lomsebenzi izokhulula inani elikhulu lokushisa, ukuze izinga lokushisa eliyinhloko likhuphuke ngokushesha, amandla aphezulu e-LED, umphumela omkhulu wokushisa. Ukwenyuka kwezinga lokushisa le-chip ye-LED kuzoholela ekushintsheni ekusebenzeni kwamadivayisi akhipha ukukhanya kanye nokunciphisa ukusebenza kahle kokuguqulwa kwe-electro-optical, ukwehluleka okukhulu noma ngisho nokwehluleka, ngokusho kokuhlolwa kokuhlola kubonisa ukuthi: I-LED ngokwayo ikhuphuka izinga lokushisa elingu-5 degrees Celsius, ukugeleza kokukhanya. iyancipha ngo-3%, ngakho-ke izibani ze-LED kufanele zinake umthombo wokukhanya we-LED ngokwawo umsebenzi wokupholisa, uma kungenzeka ukukhulisa indawo yokupholisa yomthombo wokukhanya we-LED ngokwawo, ngangokunokwenzeka ukunciphisa izinga lokushisa le-LED. ngokwalo, uma izimo zivuma, ingxenye yokuphakelwa kwamandla ihlukaniswa nengxenye yomthombo wokukhanya, Akufiseleki ukuphishekela usayizi omncane futhi indiva izinga lokushisa lokusebenza kwezibani nempahla yamandla.
