Izizathu zokucekelwa phansi kwewasha odongeni lwe-LED
Iwasha odongeni lwe-LED iyilambu lamandla aphansi-voltage aphansi, elizwela kakhulu ku-voltage. Ngakho-ke, ukukhanya kwayo yonke i-LED ngokuvamile kulawulwa okwamanje, futhi inani eliphakeme lamanje elisebenzayo liyi-20 mA. Uma i-current idlula leli nani eliphakeme, izobangela kalula ukuthi iwasha yodonga ye-LED ibhujiswe.
Ngokusekelwe kulesi simiso, izizathu zokucekelwa phansi kwe-washer yodonga lwe-LED empilweni yangempela zivame ukuba nalezi zici ezilandelayo:
Okokuqala: ukungena kwamanzi. Lapho izibani ze-LED zisebenzisa izinto ezihlukile ezingangeni manzi, amandla okusebenza okungangeni manzi kanye nobude bempilo yokusebenza okungangeni kwamanzi kuhlukile. Ngemuva kokuthi ezinye izinto ze-LED ezingangeni manzi seziguga futhi ziphelelwe yisikhathi, amanzi azongena futhi abangele ukuthi isekethe ihambe kancane.
Okwesibili: Umshayeli noma ubuhlalu besibani bulimele. Uma kuqhathaniswa, kumalambu e-LED, umshayeli nobuhlalu belambu kulula ukuphuka. Ngenxa yokuthi i-voltage yokusebenza yezibani ze-LED ngokuvamile ingu-24V, futhi i-voltage elinganiselwe yamanje eshintshayo ingu-220V, ngokuvamile kuyadingeka ukuthi udlule kumshayeli ukuze wenze i-voltage eguquguqukayo kanye nenqubo yamanje ezinzile. Ukukhethwa kokushayela emakethe nakho kuyahlukahluka, ngamadola ambalwa kokubi kanye nenqwaba yamadola kokuhle. Ngakho-ke, isikhathi sokuphila sokushayela siyahlukahluka kuye ngekhwalithi. Uma umshayeli engasebenzi ngokujwayelekile, kuzophinde kubangele i-voltage engavamile kanye namanje, okuzogcina kuholele ekubhujisweni kwayo yonke ibha yokukhanya. Ubuhlalu bezibani ngokuyisisekelo busetshenziswa abakhiqizi abakhulu, futhi impilo yabo evamile ngokuvamile iphakeme. Kodwa-ke, ubuhlalu besibani buthintwa imvelo (ukushisa okuphezulu). Ngakho-ke, kulula ukuwaphula.
Okwesithathu: ukufanisa ingxenye. Yilapho i-capacitance kanye nokumelana kungalingani ngesikhathi sokubala, ngemva kwesikhathi esithile sokusetshenziswa, umbane ongavamile uzokwenzeka, ozoshisa yonke isifunda.
Okungenhla yizizathu ezijwayelekile zokucekelwa phansi kwewasha odongeni lwangaphandle. Kungase kube nezinye izizathu, kodwa azivamile.
