Okwamanje, kukhonaokungahlukaniswangaukuklama kanyeukushayela okuhlukileukuhlinzekwa kukagesi emakethe yokukhanyisa i-LED.
Umklamo ongahlukanisiwe ukhawulelwe emikhiqizweni efakwe ugesi kabili, njengokukhanya okufakwa esikhundleni kwebhalbhu, lapho i-LED kanye nomkhiqizo wonke kuhlanganiswe futhi kuvaliwe ngepulasitiki engahambisani nogesi, ngakho-ke akukho bungozi bokushaqeka kukagesi kumsebenzisi wokugcina.
Njengoba kuboniswe ku-isithombe
lapho umsebenzisi ekwazi ukuthinta i-LED kanye nezintambo zokukhipha, kudingeka ugesi wedrayivu ehlukanisiwe.
I-transformer ehlukanisiwe noma ugesi we-LED drive ohlukanisiwe usho ukuthi i-LED ingathintwa ngqo ngesandla ngaphandle kokushiswa ngogesi. Nakuba amandla e-LED drive ngaphandle kwe-transformer ehlukanisiwe esengafinyelela ukuvikela okuyingxenye ngosizo lwegobolondo elivikelayo, i-LED okwamanje ayikwazi ukuthintwa ngqo lapho isebenza. Izibani ezivalekile zizoba yinto evamile esikhathini esizayo.
Njengoba kuboniswe esithombeni
Uhlobo olungahlukaniswanga kanye nohlobo olulodwa lwe-LED drive supply lunezinzuzo nezinkinga zalo, ikakhulukazi kusukela kumaphuzu amane alandelayo:
Ngokuphathelene nokuphepha:ugesi wokuzihlukanisa unezinzuzo eziningi, ngoba ugesi wohlobo lokuzihlukanisa one-voltage ebanzi, ukusebenza kungcono futhi kuzinzile, futhi ngeke kubangele noma yimuphi umonakalo emzimbeni womuntu, futhi ubuchwepheshe bokuzihlukanisa bukhula kakhulu. Uhlobo olungahlukaniswanga ububanzi bamandla kagesi bubi kancane kunobokuzihlukanisa, ububanzi bamandla kagesi buphakathi110V-300V, futhi ukuzihlukanisaugesi ungenza60-300V, ugesi ophezulu nophansi ufana kakhulu.
Ngokuphathelene nokusebenza kahle:ukuphepha kokushayela uhlobo lokuzihlukanisa kodwa ukusebenza kahle okuphansi, ukusebenza kahle kokushayela uhlobo lokungazihlukanisi kuphakeme.
Ngokuphathelene nesakhiwo sesekethe:Uhlelo lwamanje lokuhlukaniswa ikakhulukazi uhlelo lwesekethe ye-AC/DC flyback, ngakho-ke isekethe ehlobene iyinkimbinkimbi kakhulu, ibiza kakhulu. Uhlobo olungahlukanisi ngokuyisisekelo lusebenzisa isekethe ye-DC/DC boost noma ye-buck, isekethe ehlobene ilula, ngakho-ke izindleko ziphansi kakhulu.
Ngokuphathelene nokunemba kwamanje okuqhubekayo:uhlobo lokuzihlukanisa lungaba ngaphakathi kuka-±5%. Kunzima ukulufinyelela uhlobo lokungazihlukanisi.
Isicelo:
1, i-IC noma ingxenye yokunikezwa kwamandla kwebhodi lesifunda, kusukela entengo kanye nomthamo, ukukhethwa kokunikezwa kwamandla okungahlukaniswanga.
2, ukusetshenziswa kwamandla ebhethri, ngokwezidingo zokuphila kwebhethri, ukukhethwa kwamandla angahlukanisiwe.
