Isahluko sesithathu: Unikezelo lwaMandla oMbane we-LED / abaqhubi beSkrini be-LED badlala indima ebalulekileyo kumboniso okhokelwayo njengentliziyo enamandla yomntu.

Iziboniso ze-LED ngokuthe ngcembe ziye zaba ziimveliso eziphambili kwintengiso yedijithali yangaphandle yekhaya, kwaye zinokubonwa kuyo yonke indawo kwiifacade zezakhiwo zangaphandle, iqonga lekonsathi, kunye nezikhululo zesikhululo, njl.

Kodwa sasisoloko siva abantu abakwishishini bekhalaza ukuba ngalo lonke ixesha isibane se-LED siphukile, iimeko ezinjengeemodyuli ezimbalwa ze-LED zimnyama ngenxa yombane ophukileyo, i-fan yokuyeka ukusebenza njl njl. Kubalulekile ukuhlalutya nzulu ukuqonda unobangela we-LED. umonakalo wonikezelo lwamandla.

Ngokukodwa, isikrini sentengiso yangaphandle sijongana nemekobume erhabaxa kwaye sidinga ukulungiswa okuthe chatha ukuze sikwazi ukusinceda ngcono.

Ukonga amandla okubonisa i-LED kunye nobomi benkonzo ziziphumo zonyuselo olucacileyo, ke uchonga ngokuchanekileyo njani kwaye ukhethe unikezelo lwamandla okubonisa i-LED kwiscreen sakho esikhokelwayo?

Okokuqala, jonga inkqubo yokubonakala ukukhetha i-LED ukubonisa amandla Supply.

Umboneleli wamandla olungileyo, ukwangqongqo kakhulu kwinkqubo yokusebenza, kuba oku kunokuqinisekisa ukuhambelana kwebhetshi yemveliso.

Kodwa umenzi ongenaxanduva, ukuveliswa kwamandla Ukubonelela ngokubonakala kwayo, i-tin, ukulungelelaniswa kwezinto azilungile ngokupheleleyo.

Okwesibini, khetha unikezelo lwamandla okubonisa i-LED ukusuka ekusebenzeni ngokupheleleyo komthwalo.

Ukusebenza kakuhle konikezelo lwamandla sesona salathisi sibaluleke kakhulu, ukusebenza kakuhle kukuphezulu kokuguqulwa kwamandla aphezulu, ukuze kufakwe kwiimfuno zokugcinwa kwamandla kunye nokukhuselwa kokusingqongileyo, kwaye ngokwenene unokugcina umbane kubasebenzisi.

Okwesithathu, i-voltage ye-output ripple yonikezelo lwamandla ombane rhoqo inkulu.

Ubungakanani bempembelelo ye-ripple inempembelelo enkulu kakhulu kubomi bezixhobo zombane.

Incinci i-ripple, ingcono.

Okwesine, jonga ukwanda kobushushu bonikezelo lwamandla ukukhetha amandla omboniso we-LED.

Ukunyuka kweqondo lokushisa kuchaphazela ukuzinza kunye nobomi bokunikezelwa kwamandla.

Iqondo lobushushu lisezantsi, ngcono.

Ukongezelela, kunokubonwa ngokusebenza kakuhle ukuba ukusebenza kakuhle kobushushu obuphezulu kuya kuba kuncinci.

Okwesihlanu, ngenxa yeepropathi zemveliso ye-LED yokubonisa, utshintsho lwangoku lwangoku luya kuveliswa xa udlala ividiyo okanye isikrini, esibeka phambili iimfuno ezingqongqo kumbane we-LED.

Ngokuqhelekileyo, ukwenzela ukuba uqinisekise usasazo oluqhelekileyo lwesikrini sokubonisa, kufuneka ugcine isixa esithile sesibonelelo sokunikezelwa kwamandla.

Isithandathu,I-mingqiqo jikelele yentsimbi, ugcino lwentsalela, ukusebenza kwemveliso unikezelo lwamandla oluzinzile ngakumbi, ixesha elide lokuphila, nangona kunjalo, ngokwandisa ixabiso lemveliso yonikezelo lwamandla, ugcino oluninzi kakhulu lwentsalela lukwalula ukubangela inkcitho.

Okwangoku, unikezelo lwamandla oNikezo lwezikrini zokubonisa i-LED kwishishini ngokuqhelekileyo lugcinwe ngu-20% - 30%.

Ukuze ukwandise ixesha lokuphila kokunikezelwa kombane, kucetyiswa ukuba ukhethe umatshini onokulinganiswa kwamandla angama-30%.

Ngokomzekelo, ukuba inkqubo idinga umbane we-100W, kuyacetyiswa ukuba ukhethe imodeli enegunya lokubonelela ngexabiso elingaphezu kwe-130W, enokuphucula ngokufanelekileyo ubomi bokunikezelwa kwamandla.

Okwesixhenxe, khetha unikezelo lwamandla ngokwecandelo lesicelo.

Umsebenzi wokukhusela: ukukhuselwa kombane, ukukhuselwa kobushushu, ukukhuselwa komthwalo ongaphezulu, njl.

Umthwalo ogqithisileyo unokubangela ukhuseleko lomthwalo ogqithisileyo. Kucetyiswa ukuba kwandiswe amandla okuphuma kombane okanye ukuguqula uyilo lomthwalo.

Kwimeko yesibini, ubushushu buphezulu kakhulu kwaye ukhuseleko lobushushu lwenzeka, zombini ziya kubeka amandla kwindawo ekhuselweyo.

Umsebenzi wesicelo: umsebenzi wesignali, umsebenzi wokulawula kude, umsebenzi we-telemetry, umsebenzi ofanayo, njl.

Umsebenzi okhethekileyo: ukulungiswa komsebenzi (PFC), umbane oqhubekayo (UPS).

Okwangoku, imithombo yamandla ekhokelwa yi-yonwaytech yokusetyenziswa kwefektri yile: Meanwell, G-Energy, Rong Electric, Yuanchi, Chuanlian, Great Wall, njl.

I-Meanwell yeyona idumileyo, kwaye uDonga Olukhulu lunokufakwa kumazwe athile anemozulu ebanda kakhulu, njengeRussia, iDenmark, iFinland kunye neSweden kuMantla Yurophu.
