Okwangoku, kukhookungahlukaniswangauyilo kunyeukuqhuba okwahlukileyoumbane ofumaneka kwimarike yezibane ze-LED.
Uyilo olungahlukaniswanga lukhawulelwe kwiimveliso ezifakwe i-insulation kabini, ezifana nokukhanya okutshintshayo kwebhalbhu, apho i-LED kunye nemveliso yonke zihlanganiswe kwaye zitywinwe kwiplastiki engangenisi umbane, ngoko ke akukho mngcipheko wokothuka ngombane kumsebenzisi wokugqibela.
Njengoko kubonisiwe kwiumfanekiso
apho umsebenzisi enokufikelela ekuchukumiseni i-LED kunye neentambo zokukhupha, kufuneka umbane we-drive ezimeleyo.
I-transformer ezimeleyo okanye umbane we-LED drive ezimeleyo ngombane uthetha ukuba i-LED inokuchukunyiswa ngqo ngesandla ngaphandle kokutsalwa ngumbane. Nangona amandla e-LED drive ngaphandle kwe-transformer ezimeleyo isenokufumana ubushushu obuncinci bomatshini ngoncedo lweqokobhe elikhuselayo, i-LED okwangoku ayinakuqhagamshelwa ngqo xa isebenza. Izibane ezigqunyiweyo ziya kuba yinto eqhelekileyo kwixesha elizayo.
Njengoko kubonisiwe kumfanekiso
Uhlobo olungahlukaniswanga kunye nohlobo olulodwa lwe-LED drive supply luneengenelo kunye neengxaki zalo, ikakhulu ukusuka kumanqaku amane alandelayo:
Ngokuphathelele ukhuseleko:umbane wokuzihlukanisa unezibonelelo ezingaphezulu, kuba umbane wohlobo lokuzihlukanisa one-voltage ebanzi, ukusebenza kwawo kungcono kwaye kuzinzile, kwaye akuyi kubangela monakalo emzimbeni womntu, kwaye iteknoloji yokuzihlukanisa ikhula ngakumbi nangakumbi. Uhlobo olungazodwa uluhlu lwe-voltage lubi kancinci kunolo lokuzihlukanisa, uluhlu lwe-voltage luphakathi110V-300Vkunye ukuzihlukanisaumbane ungenza60-300V, umsinga ophezulu nophantsi ufana kakhulu.
Ngokuphathelele ukusebenza kakuhle:ukhuseleko lokuqhuba uhlobo lokuzihlukanisa kodwa ukusebenza kakuhle okuphantsi, ukusebenza kakuhle kokuqhuba uhlobo lokungazihlukanisi kuphezulu.
Ngokwesakhiwo sesekethe:Inkqubo yokuzihlukanisa yangoku ikakhulu yinkqubo yesekethe ye-AC/DC flyback, ngoko ke isekethe enxulumeneyo iyinkimbinkimbi ngakumbi, ineendleko eziphezulu. Uhlobo olungabandakanyiyo ukuhlukaniswa ngokuyintloko lusebenzisa isekethe ye-DC/DC boost okanye ye-buck, isekethe enxulumeneyo ilula, ngoko ke ixabiso liphantsi.
Ngokuphathelele ukuchaneka kwangoku okuqhubekayo:Uhlobo lokuzahlula lunokuba ngaphakathi kwe-±5%. Kunzima ukufikelela kuhlobo lokungazahluli.
Isicelo:
1, i-IC okanye inxalenye yombane webhodi yesekethe, ukusuka kwixabiso kunye nomthamo, ukukhethwa kombane ongahlukaniswanga.
2, ukusetyenziswa kombane webhetri, kwiimfuno zobomi bebhetri, ukukhethwa kombane ongabodwa.
