Izizathu zokutshatyalaliswa kwewashi yodonga lwe-LED
Iwasha eludongeni lwe-LED sisibane esine-low-voltage esine-low-power, esinovelwano ngakumbi kumbane. Ngoko ke, ukukhanya kwe-LED yonke ngokuqhelekileyo kulawulwa ngoku, kwaye ixabiso eliphakamileyo lalo lonke elisebenzayo liyi-20 mA. Ukuba i-current idlula eli xabiso lencopho, iya kubangela ukuba i-washer yodonga lwe-LED itshatyalaliswe.
Ngokusekelwe kulo mgaqo, izizathu zokutshatyalaliswa kodonga lwe-LED ebomini bokwenene zinemiba elandelayo:
Eyokuqala: ingenamanzi. Xa izibane ze-LED zisebenzisa izinto ezahlukeneyo ezingenamanzi, amandla okusebenza kwamanzi kunye nobude bobomi bokusebenza kwamanzi ahlukeneyo. Emva kokuba ezinye izinto ze-LED ezingenamanzi ziguga kwaye ziphelelwe lixesha, amanzi aya kungena kwaye abangele ukuba isekethe ihambe ngokukhawuleza.
Okwesibini: Umqhubi okanye intsimbi yesibane yonakele. Ngokwentelekiso, kwizibane ze-LED, umqhubi kunye neentsimbi zesibane kulula ukuziqhekeza. Ngenxa yokuba i-voltage esebenzayo yezibane ze-LED idla ngokuba yi-24V, kwaye i-voltage elinganisiweyo ye-alternating current yi-220V, kudla ngokufuneka ukuba uhambe ngomqhubi ukuze enze umbane oguquguqukayo kunye nenkqubo yangoku ezinzileyo. Ukhetho lweedrive kwimarike lukwahluka, kunye needola ezimbalwa ezimbi kunye needola ezininzi ezilungileyo. Ngoko ke, ubude bokuphila bokuqhuba buhluka ngokuxhomekeke kumgangatho. Xa umqhubi engasebenzi ngokuqhelekileyo, kuya kubangela ukuba i-voltage engavamile kunye nekhoyo ngoku, ekugqibeleni iya kukhokelela ekubhujisweni kwebha yokukhanya yonke. Amaso esibane ngokusisiseko asetyenziswa ngabavelisi abakhulu, kwaye ubomi babo obuqhelekileyo buphezulu. Nangona kunjalo, iintsimbi zesibane zichaphazeleka ngokusingqongileyo (ubushushu obuphezulu). Ngoko ke, kulula ukuziqhawula.
Okwesithathu: ukuhambelana kwecandelo. Oku kuxa i-capacitance kunye nokuchasana kungahambelani ngexesha lokubala, emva kwexesha elithile lokusetyenziswa, umsinga ongaqhelekanga uya kwenzeka, oya kutshisa isiphaluka sonke.
Ezi zingentla zizizathu eziqhelekileyo zokutshatyalaliswa kwewashi eludongeni lwangaphandle. Kusenokubakho ezinye izizathu, kodwa zinqabile.
