Okwangoku, zikhoabangabodwauyilo kunyeuqhube yedwaukunikezelwa kwamandla kwimarike yokukhanyisa i-LED.
Uyilo olungabodwa lukhawulelwe kwiimveliso ezifakwe kabini, ezinje ngokukhanya okutshintshiweyo kwebhalbhu, apho i-LED kunye nayo yonke imveliso idityaniswe kwaye itywinwe kwiplastiki engasebenziyo, ngoko akukho mngcipheko wokothuka kombane. umsebenzisi wokugqiba.
Njengoko kubonisiwe kwiumfanekiso
apho umsebenzisi unokufikelela ekuchukumiseni i-LED kunye nocingo oluphumayo, unikezelo lwamandla olwenziwa yedwa luyafuneka.
I-transformer eyodwa okanye umbane obekwe yedwa we-LED drive uthetha ukuba i-LED inokuchukunyiswa ngokuthe ngqo ngesandla ngaphandle kokubanjwa ngumbane. Nangona amandla e-LED drive ngaphandle kwe-transformer yodwa angakwazi ukufikelela kwi-partial insulation mechanical ngoncedo lwegobolondo elikhuselayo, i-LED ngeli xesha ayinakuqhagamshelwa ngokuthe ngqo xa isebenza. Izibane ezigqunyiweyo ziya kuba yinto eqhelekileyo kwixesha elizayo.
Njengoko kubonisiwe kumfanekiso
Uhlobo olungelulo lodwa kunye nohlobo olulodwa lwe-LED drive unikezelo lwamandla ukuba lube nezibonelelo zabo kunye nokungalunganga, ngakumbi kula manqaku mane alandelayo:
Ngokokhuseleko:unikezelo lwamandla odwa luneenzuzo ezininzi, ngenxa yokuba unikezelo lwamandla olwenziwa lulodwa olunombane obanzi, ukusebenza kubhetele kwaye kuzinzile, nako akuyi kubangela ingozi kumzimba womntu, kwaye itekhnoloji yokwahlula ikhula ngakumbi nangakumbi. Uhlobo olungelulo lodwa uluhlu lwamandla ombane lubi kancinci kunokwahlulwa, uluhlu lombane luphakathi110V-300V, kwaye ukuba wedwaunikezelo lwamandla lungenza60-300V, ephezulu kunye nephantsi yangoku ifana kakhulu.
Ngokumalunga nokusebenza kakuhle:Ukhuseleko lohlobo lokuhlala wedwa kodwa ukusebenza kakuhle okuphantsi, ukuphumelela kohlobo lokungahlukanisi kuphezulu.
Ngokwesakhiwo sesekethe:iskimu sokuzihlukanisa sangoku sisininzi se-AC / DC isikimu sesekethe ye-flyback, ngoko ke isekethe ehambelanayo inzima kakhulu, ixabiso eliphezulu. Uhlobo olungelulo lodwa lusebenzisa i-DC/DC boost okanye i-buck circuit, i-circuit yesalamane ilula, ngoko ke ixabiso liphantsi.
Ngokokuchaneka okuthe rhoqo kwangoku:uhlobo lokuzihlukanisa lunokuba phakathi kwe ±5%. Kunzima ukufezekisa uhlobo lokungakhethi.
Isicelo:
I-1, i-IC okanye inxalenye yebhodi yesiphaluka unikezelo lwamandla, ukusuka kwixabiso kunye nomthamo, ukukhethwa kombane ongekho yedwa.
I-2, ukusetyenziswa konikezelo lwamandla ebhetri, kwiimfuno zobomi bebhetri, ukukhethwa konikezelo lwamandla olungekho lodwa.
