Incazelo Eyisisekelo Yokuhlinzeka Amandla Omshayeli We-LED
Ukunikezwa kwamandla kuyidivayisi noma ithuluzi eliguqula amandla kagesi ayisisekelo ngokusebenzisa amasu okuguqula abe amandla kagesi esibili adingwa izinto zikagesi.Amandla kagesi esivame ukuwasebenzisa ekuphileni kwethu kwansuku zonke asuselwa kumandla kagesi aguquliwe, amandla ashisayo, amandla amakhemikhali, njll. Amandla kagesi atholakala ngokuqondile emishinini yokuphehla amandla abizwa ngokuthi amandla kagesi ayisisekelo.Ngokuvamile, amandla kagesi ayisisekelo awahlangabezani nezidingo zomsebenzisi.Yilapho kutholakala khona amandla kagesi, okuguqula amandla kagesi ayisisekelo abe amandla kagesi esibili adingekayo.
Incazelo: Ukunikezwa kwamandla komshayeli we-LED kuwuhlobo lwamandla kagesi aguqula amandla kagesi ayisisekelo asuka emithonjeni yangaphandle aye emandleni kagesi esibili adingwa ama-LED.Iyunithi yokuphakela amandla eguqula ukunikezwa kwamandla ku-voltage ethile kanye neyamanje ukuze ishayele ukukhishwa kokukhanya kwe-LED.Amandla okufakwayo okunikezwa kwamandla kamshayeli we-LED ahlanganisa kokubili i-AC ne-DC, kuyilapho amandla okukhiphayo ngokuvamile agcina igagasi elingaguquki elingashintsha i-voltage ngezinguquko ku-voltage eya phambili ye-LED.Izingxenye zayo eziyinhloko zihlanganisa ngokuyinhloko amadivayisi okuhlunga okokufaka, izilawuli zokushintsha, ama-inductors, amashubhu okushintsha e-MOS, izinqamuleli zempendulo, amadivayisi okuhlunga okukhiphayo, njll.
Izigaba Ezihlukahlukene Zezinsiza Zamandla Omshayeli We-LED
Izinsiza zamandla omshayeli we-LED zingahlukaniswa ngezindlela ezahlukahlukene.Ngokuvamile, zingahlukaniswa zibe izinhlobo ezintathu ezinkulu: shintsha imithombo yamanje engashintshi, izinsiza zamandla ze-IC ezilayini, kanye namandla okunciphisa amandla okunciphisa.Ngaphezu kwalokho, ngokusekelwe ezilinganisweni zamandla, amandla omshayeli we-LED angaphinde ahlukanise phakathi kwamandla aphezulu, amandla aphakathi nendawo, kanye nezinsiza zomshayeli wamandla aphansi.Mayelana nezindlela zokushayela, amandla omshayeli we-LED angaba yizinhlobo zamanje zamanje noma ezingashintshi.Ngokusekelwe esakhiweni sesifunda, amandla omshayeli we-LED angahlukaniswa njengokunciphisa amandla, ukunciphisa i-transformer, ukunciphisa ukumelana, ukunciphisa i-RCC, nezinhlobo zokulawula i-PWM.
I-LED Driver Power Supply - Ingxenye Eyinhloko Yokulungiswa Kokukhanyisa
Njengengxenye ebalulekile yezibani ze-LED, ukunikezwa kwamandla kamshayeli we-LED kufinyelela ku-20% -40% wezindleko zokulungiswa kwe-LED, ikakhulukazi emikhiqizweni yokukhanyisa i-LED enamandla aphakathi nendawo ukuya phezulu.Izibani ze-LED zisebenzisa ama-semiconductor chips njengezinto ezikhipha ukukhanya futhi zinezinzuzo ezifana nokusebenza kahle kwamandla, ubungane bemvelo, ukunikezwa kwemibala okuhle, nesikhathi sokuphendula ngokushesha.Njengohlobo oluvame ukusetshenziswa lokukhanyisa emphakathini wanamuhla, izinqubo zokukhiqiza izibani ze-LED zibandakanya izinyathelo ezingu-13 ezibalulekile, okuhlanganisa ukusika izintambo, ukunamathisela ama-chips e-LED, ukwenza amabhodi wezibani, ukuhlola amabhodi wezibani, ukusebenzisa i-silicone conductive eshisayo, njll. Isinyathelo ngasinye sokukhiqiza sifuna. izindinganiso eziqinile zekhwalithi.
Umthelela Ojulile Wokuhlinzekwa Kwamandla Omshayeli We-LED Embonini Yokukhanyisa Kwe-LED
Izinsiza zamandla omshayeli we-LED zihlangana nemithombo yokukhanya ye-LED kanye nezindlu ukuze zenze imikhiqizo yokukhanyisa i-LED, esebenza njengezingxenye zazo eziyinhloko.Ngokuvamile, zonke izibani ze-LED zidinga ukunikezwa kwamandla omshayeli we-LED ofanayo.Umsebenzi oyinhloko wokunikezwa kwamandla kamshayeli we-LED ukuguqula ukunikezwa kwamandla kwangaphandle ku-voltage ethize kanye neyamanje ukushayela imikhiqizo yokukhanyisa kwe-LED ukuze kukhanye nokulawula okuhambisanayo.Badlala indima ebalulekile ekuthuthukiseni ukusebenza kahle, ukuzinza, ukwethembeka, nempilo yemikhiqizo yokukhanyisa kwe-LED, okunomthelela omkhulu ekusebenzeni kwayo nekhwalithi.Ngokwezibalo zabakhiqizi abaningi bamalambu asemgwaqweni, cishe u-90% wokwehluleka kwezibani zasemgwaqweni ze-LED namalambu omhubhe kubangwa amaphutha okunikezwa kwamandla omshayeli nokungathembeki.Ngakho-ke, ukunikezwa kwamandla kamshayeli we-LED kungenye yezinto ezibalulekile ezithonya ukuthuthukiswa kwemboni yezibani ze-LED.
Izibani ze-LED Ziqondanise Ngokujulile Nethrendi Yokuthuthukiswa Okuluhlaza
Ama-LED aqhosha ngokusebenza okuvelele, futhi amathemba awo esikhathi eside anethemba.Eminyakeni yamuva nje, njengoba inkinga yesimo sezulu yomhlaba ikhula, ukuqwashisa ngemvelo komphakathi bekulokhu kukhula.Umnotho wekhabhoni ephansi usuphenduke isivumelwano sokuthuthukiswa komphakathi.Emkhakheni wokukhanyisa, amazwe emhlabeni jikelele ahlola ngenkuthalo imikhiqizo ephumelelayo nezindlela zokuzuza ukongiwa kwamandla kanye nokunciphisa ukukhishwa.Uma kuqhathaniswa neminye imithombo yokukhanya efana nama-incandescent nama-halogen, izibani ze-LED ziwumthombo wokukhanya okuluhlaza onezinzuzo ezifana nokusebenza kahle kwamandla, ukuvumelana kwemvelo, ukuphila isikhathi eside, ukuphendula okusheshayo, nokuhlanzeka kombala okuphezulu.Ngokuhamba kwesikhathi, izibani ze-LED ziqondana ngokujulile nenkambiso yenkathi yentuthuko eluhlaza kanye nomqondo wentuthuko esimeme, elungele ukuvikela indawo ehlala njalo emakethe yokukhanyisa enempilo neluhlaza.
Ukukhishwa Kwezinqubomgomo Zomkhakha Ezikhuthaza Ukuthuthukiswa Kwesikhathi Eside Kwemboni Yabashayeli
Ngezinqubomgomo eziqinisa umkhakha, ukushintshwa kwezibani ze-LED kusethubeni.Ngenxa yokusebenza kwayo okuphezulu kanye nezici zokonga amandla, ukukhanya kwe-LED kusebenza njengenye indlela enhle kakhulu emithonjeni yendabuko esebenzisa amandla aphezulu.Ngokumelene nesizinda sezinkinga zemvelo ezikhulayo, amazwe emhlabeni jikelele agxila kakhulu ekongiweni kwamandla kanye nokunciphisa ukungcola, eqhubeka nokukhulula izinqubomgomo ezihlobene nokukhanyisa okuluhlaza.Imboni ye-LED isiphenduke enye yezimboni ezinamasu ezisafufusa ezweni lethu.Amandla kagesi abashayeli be-LED kulindeleke ukuthi ahlomule kakhulu ekusekelweni kwenqubomgomo, kungenise isigaba esisha sokukhula.Ukukhishwa kwezinqubomgomo zemboni kunikeza isiqinisekiso sokuthuthukiswa kwesikhathi eside kwezinto ezinikezwa amandla abashayeli be-LED.
