Okwamanje, zikhonaabangabodwadesign kanyeidrayivu eyodwaukunikezwa kwamandla emakethe yezibani ze-LED.
Idizayini engahlukanisiwe ikhawulelwe emikhiqizweni evalwe kabili, njengesibani esishintshayo se-bulb, i-LED kanye nomkhiqizo wonke kuhlanganiswe futhi kufakwe uphawu ngepulasitiki engeyona e-conductive, ngakho-ke abukho ubungozi bokushaqeka kukagesi umsebenzisi wokugcina.
Njengoba kuboniswe kuisithombe
lapho umsebenzisi ekwazi ukuthinta i-LED kanye nezintambo eziphumayo, ukunikezwa kwamandla edrayivu ehlukanisiwe kuyadingeka.
I-transformer ehlukanisiwe noma amandla kagesi edrayivu ye-LED ehlukanisiwe asho ukuthi i-LED ingathintwa ngokuqondile ngesandla ngaphandle kokubanjwa ugesi.Nakuba amandla okushayela kwe-LED ngaphandle kwe-transformer yokuhlukanisa angakwazi ukufeza ukufakwa kwemishini ngokwengxenye ngosizo lwegobolondo elivikelayo, i-LED ngalesi sikhathi ayikwazi ukuthintwa ngokuqondile lapho isebenza.Izibani ezivalekile zizoba yinsakavukela esikhathini esizayo.
Njengoba kuboniswe emfanekisweni
Uhlobo olungahlukanisiwe nohlobo oluhlukile lokunikezwa kwamandla kagesi we-LED ukuze kube nezinzuzo nezinkinga zabo, ikakhulukazi kulawa maphuzu amane alandelayo:
Mayelana nokuphepha:ukunikezwa kwamandla okuzihlukanisa kunezinzuzo eziningi, ngoba uhlobo lokuzihlukanisa lunikezwa amandla ane-voltage ebanzi, ukusebenza kungcono futhi kuzinzile, futhi ngeke kubangele noma yimuphi umonakalo emzimbeni womuntu, kanye nobuchwepheshe bokuzihlukanisa bukhula ngokwengeziwe.Uhlobo olungezodwa uhla lwe-voltage lubi kancane kunokuhlukaniswa, ububanzi be-voltage buphakathi110V-300V, futhi ukuzihlukanisaukunikezwa kwamandla kungakwenza60-300V, high and low current is iyunifomu kakhulu.
Mayelana nokusebenza kahle:Ukuphepha kohlobo lwe-isolation drive kodwa ukusebenza kahle okuphansi, ukusebenza kahle kohlobo lwe-non-isolation drive kuphezulu.
Ngokuya ngesakhiwo sesekhethi:uhlelo lwamanje lokuzihlukanisa luwuhlelo lwesekethe ye-AC/DC ye-flyback, ngakho-ke umjikelezo ohlobene uyinkimbinkimbi kakhulu, ubiza kakhulu.Uhlobo olungahlukanisi ngokuyisisekelo lusebenzisa i-DC/DC boost noma i-buck circuit, isifunda esihlobene silula, ngakho-ke izindleko ziphansi.
Ngokuvumelana nokunemba okungaguquki kwamanje:uhlobo lokuzihlukanisa lungaba phakathi kuka-±5%.Uhlobo lokungahlukanisi kunzima ukufeza.
Isicelo:
I-1, i-IC noma ingxenye yokunikezwa kwamandla ebhodi lesifunda, kusukela ngentengo nevolumu, ukukhethwa kokunikezwa kwamandla okungahlukanisiwe.
2, ukusetshenziswa kwamandla ebhethri, kuzidingo zempilo yebhethri, ukukhethwa kokunikezwa kwamandla okungahlukanisiwe.
