Kutalika kwa dalaivala wa LED
Pali zinthu zambiri zomwe zingakhudze moyo wa driver wanu wa LED, kuphatikiza:
Ubwino wa woyendetsa wa LED.
Mtundu wa dalaivala wa LED umasankhidwa.
Kuyika chilengedwe.
Ubwino wa woyendetsa wa LED
Kunena zoona, zomwe mumapeza ndizomwe mumalipira. Mukagula woyendetsa wotchipa wa LED, moyo wake sungakhale wautali choncho. Madalaivala otsika mtengo a LED awa amagwiritsidwa ntchito kwambiri pamsika wogulitsa, pomwe mitengo yotsika ndi imodzi mwazinthu zopangira zisankho kwa ogwiritsa ntchito kumapeto. Sanapangidwe pamtengo wapamwamba chifukwa amatha kukhala okwera mtengo, zomwe zimapangitsa kuti zikhale zodula kwambiri kuti zigulitse m'masitolo ena ogulitsa.
MEANWELL LED woyendetsa ali ndi moyo wautali wautumiki. Tsamba lazinthu zomwe mungatsitse patsamba lawo ngakhale mndandanda wanthawi yayitali pakati pa kulephera (MTBF) data. Ichi ndichifukwa chake MEAN WELL ndiye chisankho choyamba pazamalonda ndi mafakitale.
Zikuyembekezeka kuti oyika mapulogalamu azamalonda ndi mafakitale azipereka nthawi yokwanira yotsimikizira, nthawi zina mpaka zaka 10. Ngati kulephera kukuchitika, woyikayo akuyembekezeka kupita kumalowo ndikulowetsa woyendetsa wolephera wa LED.
Mtundu wosankhidwa wa driver wa LED
Ndikofunikira kuti mtundu weniweni wa dalaivala wosankhidwa wa LED ukhale woyenera pa cholingacho.
Mungagwiritse ntchito dalaivala wa LED wokhala ndi mphamvu yapamwamba kuposa mphamvu yofunikira kuti muyambe kuyendetsa LED, koma simungagwiritse ntchito dalaivala wokhala ndi mphamvu yochepa. Izi zidzapangitsa kuti dalaivala wa LED azidzaza kwambiri, motero amafupikitsa kwambiri moyo wa dalaivala wa LED.
Kuti mutetezeke, tikukulimbikitsani kuti mungokweza dalaivala wa LED mpaka 75% ~ 80% ya mphamvu zake zovotera.
Chilengedwe chokhazikitsa dalaivala wa LED
Ngati mumagwiritsa ntchito dalaivala wa LED panja, chonde onetsetsani kuti ili ndi digirii yokwanira yachitetezo (IP). IP65 iyenera kukhala yocheperako, koma IP67 ndiye chisankho choyamba. Chiwerengero cha IP chikuwonetsa kukana fumbi ndi chinyezi choperekedwa ndi woyendetsa LED.
Onaninso kutentha kwa ntchito kwa woyendetsa LED. Izi zidzanenedwa mu pepala lazinthu zamalonda. Mukufuna kuwonetsetsa kuti dalaivala wa LED adapangidwa kuti azigwira ntchito kutentha komwe kukuyembekezeka.
Dongosolo la data likuwonetsanso mayendedwe opotoka. Mofanana ndi zipangizo zambiri zamagetsi, kuwonjezeka kwa kutentha kwa dalaivala wa LED kudzachepetsa mphamvu. Ngati mukufuna kugwiritsa ntchito dalaivala wa LED pamalo otentha, yang'anani mayendedwe okhotakhota kuti muwonetsetse kuti katundu wofunikira atha kutengedwabe kuchokera kwa dalaivala wa LED pamatenthedwe apamwamba. Ngati sichoncho, muyenera kusankha dalaivala wa LED wokhala ndi mphamvu yayikulu kuposa momwe amayembekezera.
