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 lokuhlukaniswa kwamandla kagesi olubanzi, ukusebenza kungcono futhi kuzinzile, futhi ngeke kubangele noma yimuphi umonakalo emzimbeni womuntu, kanye nobuchwepheshe bokuzihlukanisa bukhula nakakhulu. 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 kungaphezulu.
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.
