Unokukhetha njani iadaptha yamandla yokukhanya kwe-LED?
2024-07-16 17:30:02
Xa ukhetha iadaptha yamandla kwizibane ze-LED, kufuneka uqwalasele ezi zinto zilandelayo zibalulekileyo:
I-voltage kunye nokuhambelana kwangoku: Okokuqala, i-voltage yokusebenza kunye ne-current yesixhobo se-LED kufuneka imiselwe. Ngokomzekelo, ii-LED ezimhlophe eziqhelekileyo zifuna i-voltage malunga ne-3V kunye ne-current yamashumi e-milliamps. Kwimicu yokukhanya kwe-LED, umbane oqhelekileyo oqhelekileyo ngumbane othe ngqo (DC) 12V okanye 24V. Ukuhambelana kwangoku kubandakanya ukusetyenziswa kwamandla kwesixhobo, ngokuqhelekileyo ngokubala amandla ewonke esixhobo kunye nokwahlula ngombane wesixhobo ukufumana umsinga ofunekayo.
I-1Amandla kunye nokusebenza kakuhle: Xa ukhetha i-adaptha yamandla, kufuneka uqwalasele amandla ayo kunye nokusebenza kakuhle. I-adaptha yamandla enento ephezulu yamandla inokuphucula ukusebenza kakuhle kokusetyenziswa kwamandla, ngaloo ndlela igcina amandla. Kwizixhobo ze-LED ezifuna ukuqhuba ixesha elide, ezifana neziboniso zangaphandle, ukukhetha i-adapter yamandla ephezulu kunokunciphisa inkunkuma yamandla kunye nokwandisa ubomi bezixhobo.
2 Ukhuseleko kunye nesiqinisekiso: Qinisekisa ukuba i-adapter yamandla oyikhethayo inesiqinisekiso sokhuseleko esiyimfuneko (njenge-CE, UL, njl.), enokuqinisekisa ukuba ihambelana nemigangatho yokhuseleko olufanelekileyo kunye nokunciphisa iingozi zokhuseleko ngexesha lokusetyenziswa.
3. Uzinzo kunye nokuthembeka: Kwizixhobo ze-LED ezifuna ukusebenza kwexesha elide, njengeenkqubo zokukhanyisa ngaphandle, kubalulekile ukukhetha i-adapter yamandla enozinzo oluphezulu kunye nokuthembeka. Uzinzo lwangoku kunye nombane unokwandisa ubomi be-LED kunye nokunciphisa ukubola kokukhanya.
4 Iiparamitha zokufaka kunye nemveliso: Qwalasela ukuba uluhlu lwamandla ombane we-adapter kufuneka luhambelane nombane wegridi kummandla wokuqinisekisa ukusebenza okuqhelekileyo kunye nokusetyenziswa ngokukhuselekileyo kweadaptha. Kwangaxeshanye, i-voltage ephumayo kunye neyangoku kufuneka ihambelane ngokungqongqo neemfuno zesixhobo se-LED ukuphepha ukonakala kwesixhobo okanye ukusebenza okulinganiselweyo.
Ukushwankathela, xa ukhetha i-adaptha yamandla kwizibane ze-LED, izinto ezifana ne-voltage, ukuhambelana kwangoku, ukusebenza kakuhle kwamandla, ukhuseleko, ukuzinza kunye nokuthembeka kufuneka kuqwalaselwe ngokubanzi ukuqinisekisa ukuba igalelo kunye nemveliso yeeparameters zeadaptha ziyahambelana neemfuno. yezixhobo ze-LED.
