Ukuchazwa Okuyisisekelo kokuhlinzekwa ngamandla kwamandla okushayela
Ukuhlinzekwa kwamandla yithuluzi noma ithuluzi eliguqula amandla okuqala kagesi ngokusebenzisa amasu wokuguqula angena emandleni kagesi wesibili adingekayo ngemishini kagesi. Amandla kagesi esivame ukusisebenzisa empilweni yethu yansuku zonke athathwe ngokuyinhloko emandleni aguquliwe emishini, amandla ashintshiwe, amandla amakhemikhali, njll. Amandla kagesi atholakala ngokuqondile kumadivayisi kagesi aphambili. Imvamisa, amandla kagesi aphansi awahlangabezani nezidingo zomsebenzisi. Yilapho ukunikezwa kwamandla kudlalwa khona, kuguqula amandla kagesi aphambili aqonde amandla athile kagesi adingekayo.
Incazelo: Ukuhlinzekwa kwamandla okushayela kwe-LED kuwuhlobo lwamandla kagesi aguqula amandla okuqala kagesi avela emithonjeni yangaphandle kumandla kagesi wesibili adingekayo ngama-LEDs. Yiyunithi yokuhlinzekwa kwamandla eguqula ukuhlinzekwa kwamandla ku-voltage ethile futhi yamanje ukushayela ukuphuma kokukhanya okukhanyayo. Amandla wokufaka we-LED Driver Power Supplies afaka zombili i-AC ne-DC, ngenkathi amandla okukhipha ngokuvamile agcina amandla aqhubekayo azoshintsha ama-voltage voltage. Izakhi zalo ezibalulekile zifaka phakathi amadivaysi okufaka okufaka, shintsha izilawuli, ama-inductures, amashubhu wokushintsha, ama-resitubsion, amadivaysi okuhlunga akhipha, njll.
Imikhakha ehlukahlukene ye-LED Driver Power Supplies
Izinsizakalo zamandla ezi-DED eziholwayo zingahlukaniswa ngezindlela ezahlukahlukene. Imvamisa, zingahlukaniswa ngezinhlobo ezintathu ezinkulu: Shintsha imithombo yamanje, i-IC Power Power Supplies, kanye nokuvuselelwa kwamandla okuvuselelwa kwamandla. Ngaphezu kwalokho, ngokuya ngezilinganiso zamandla, okuhlinzekwayo kwamandla okushayela ama-LED kungaqhubeka ngezigaba kumandla aphezulu, aphakathi nendawo, kanye nezinto ezinamandla zomshayeli. Mayelana nezindlela zokushayela, okuhlinzekwayo kwamandla okushayela kwama-LED kungahle kube nezinhlobo zamandla eziguqukayo zamanje noma ezihlala njalo. Ngokusekelwe esakhiweni sesekethe, izinsiza zamandla okushayela eziholwayo zingahlukaniswa njengokuncishiswa kwamandla, ukuncishiswa kwe-transformer, ukuncishiswa kokuphikiswa, ukuncishiswa kwe-RCC, kanye nezinhlobo zokulawula ze-PWM, kanye ne-PWM, kanye nezinhlobo zokulawula ze-PWM, kanye ne-PWM yokulawula i-Pwm
Ukunikezwa kwamandla okushayela kwe-LED - Ingxenye Eyisisekelo yokulungiswa kokukhanyisa
Njengengxenye ebaluleke kakhulu yokulungiswa kokukhanyisa kwe-LED, i-akhawunti ye-LED Driver Supplies ye-Akhawunti ye-20% -40% yezindleko zokulungiswa kwe-LED, ikakhulukazi emikhiqizweni yokukhanyisa e-LED ephezulu. Izibani ze-LED zisebenzisa ama-semiconductor njengezinto zokwakha ezikhanyayo futhi zinezinzuzo ezinjengokusebenza kwamandla, ubungane bezemvelo, isikhathi sokuphendula okuhle, nesikhathi sokuphendula okusheshayo, nesikhathi sokuphendula okusheshayo, nesikhathi sokuphendula okusheshayo, nesikhathi sokuphendula okusheshayo, nesikhathi sokuphendula okusheshayo, nesikhathi sokuphendula esisheshayo, nesikhathi sokuphendula okusheshayo, nesikhathi sokuphendula okusheshayo, nesikhathi sokuphendula esisheshayo, nesikhathi esifanele sokuphendula. Njengohlobo oluvame ukusetshenziswa kokukhanyisa emphakathini wanamuhla, izinqubo zokukhanyisa zokukhanyisa ze-LED zibandakanya izinyathelo eziyi-13, kufaka phakathi ukugawulwa kwentambo, ukwenza ama-silicone we-LED, njll. Isinyathelo ngasinye sokukhiqiza sifuna amazinga ekhwalithi aqinile.
Umthelela Omkhulu Wokuhlinzekelwa Kwamandla Wokushayela Kwe-LED embonini yokukhanyisa ye-LED
I-LED Driver Power Supplies ihlangana nemithombo yokukhanya ye-LED nezindlu ukwakha imikhiqizo yokukhanyisa ye-LED, isebenza njengezakhi zazo eziyinhloko. Imvamisa, zonke izibani ze-LED zidinga ukuhlinzekwa ngamandla komshayeli we-LED. Umsebenzi oyinhloko we-LED Driver Power Supplies ukuguqula ukunikezwa kwamandla kwangaphandle ku-voltage ethize futhi yamanje ukushayela imikhiqizo yokukhanyisa ye-LED ukuze kukhanye nokulawulwa okuhambisanayo. Badlala indima ebalulekile ekwandiseni ukusebenza kahle, ukuqina, ukuthembeka, kanye nesikhathi sokuphila semikhiqizo yokukhanyisa ye-LED, okunomthelela omkhulu ekusebenzeni kwabo nekhwalithi yabo. Ngokusho kwezibalo ezivela kubakhiqizi be-Streetlight, cishe ama-90% ezehluleka ezindaweni ezinamalambu ezilayishwe kanye namalambu ezincwadi kuthiwa ama-driver anika amandla okunikeza amaphutha nokungabi okungatholakali. Ngakho-ke, i-LED Driver Power Supplies yakha enye yezinto ezibucayi ezinethonya ekwakhiweni kwemboni yokukhanyisa ye-LED.
Izibani ze-LED zihambisana kakhulu nomkhuba wokuthuthuka okuluhlaza
Ama-LEDs aqhayisa ukusebenza okuvelele, futhi amathemba abo wesikhathi eside anethemba. Eminyakeni yamuva nje, ngesimo sezulu sezulu sezulu siqinisa, ukuqwashisa emphakathini kwemvelo bekulokhu kukhula. Umnotho wekhabhoni ophansi usephenduke isivumelwano sokuthuthukiswa komphakathi. Emkhakheni wokukhanyisa, amazwe omhlaba wonke ahlola ngenkuthalo imikhiqizo ephumelelayo nezindlela zokuthola ukulondolozwa kwamandla nokuncishiswa kokuphuma. Qhathanisa neminye imithombo yokukhanya efana ne-incandescent nama-halogen ama-halogen, amalambu aholwa yi-green light of inzuzo enjengezinzuzo zamandla, ubungane bezemvelo, ukuphendula okusheshayo, kanye nokuhlanzeka kombala ophakeme. Ngokuhamba kwesikhathi, amalambu aholwa ngokujulile enza umkhuba wesikhathi wokuthuthuka okuluhlaza kanye nomqondo wentuthuko esimeme, ulungele ukuvikela isikhundla esihlala njalo emakethe yokukhanyisa enempilo neluhlaza.
Ukukhishwa Kwezinqubomgomo Zomkhakha Ukukhuthaza Ukuthuthukiswa Kwesikhathi Eside Kwemboni Yomshayeli
Ngezinqubomgomo eziqinisa umkhakha, ukufakwa esikhundleni kwe-LED ukukhanyisa amathuba. Ngenxa yokusebenza kwayo okuphezulu kanye nezimpawu zokonga amandla, ukukhanyisa kwe-LED kusebenza njengenye indlela enhle kakhulu emithonjeni yendabuko edla amandla. Ngokumelene ne-backrop yokwenyuka kwezinkinga zemvelo, amazwe omhlaba wonke aya ngokuya egxila ekuqothulweni kwamandla nokuncishiswa kokuphuma, ukuqhubeka nokukhipha izinqubomgomo ezihlobene nokukhanyisa okuluhlaza. Imboni ye-LED isibe ngenye yezimboni ezisafufusa ezweni lethu. Izinsizakusebenza zamandla ezi-LED zilindelwe ukuthi zizuze kakhulu ekusekelweni kwenqubomgomo, ekuhambeni esigabeni esisha sokukhula. Ukukhishwa kwezinqubomgomo zezinqubomgomo zinikeza isiqinisekiso sokuthuthukiswa kwesikhathi eside kwamandla wamandla okushayela aholwa.
