Iziphumo zamandla kwi-enterlassis ekhokelweyo

Into yamandla yiparameter ebalulekileyo yezibane ezikhokelweyo, akunandabaI-Lampment ye-LEDokanye izibane ezikhoyo ze-LED. Ke masiqonde ngakumbi ukuba yintoni eyona nto iphambili.

1, amandla
Into yamandla ibonisa ubuchule beI-LED ye-LEDUkukhupha amandla asebenzayo. Amandla ngumgangatho weqondo lokuhambisa lamandla, nakwimijikelezo ye-DC yimveliso ye-voltage v kunye nenkqubo ye-AC. Umahluko phakathi kwamandla abonakalayo kunye nesona sizathu sikhokelela kwi-mbane, kwaye into enamandla mayilingane nomyinge wamandla abonakalayo. Ke olona gunya kwi-AC Inkqubo ilingana namaxesha ombane axhomekeke kuwe.
Yiyo le: Kuphela yintombi yomthwalo onamacala anje nge-heater yombane kunye ne-bulb yokukhanya ngu-1. Umahluko phakathi kwezixhobo ezininzi kunye nokubonakala, ngelixa umehluko omkhulu kwaye ubalulekile.

I-2, elibonakalayo
Amandla asebenzayo: imveliso yevolthi ye-oc kunye ne-AC yangoku. Ngefomula njenge: s = ui. Apho i-S i-SIT EXPUPE POPE PHUPHA KWI-VA (Volt-Amprere); I-UTeation Powlic Powtage kwi-V, njenge-220v, i-380v, njl.; Imveliso yemveliso yangoku kwi-A. Igunya elibonakalayo linamacandelo amabini: amandla asebenzayo (P) kunye namandla asebenzayo (q). Amandla asebenzayo abhekisa kwinxalenye yomsebenzi owenzi ngqo. Umzekelo, ukukhanya phezulu, ukujikeleza kwemoto, ukusebenza kwesekethe. Kuba la mandla ashushu, angaziva evinjelwe ngokuthe ngqo ngabantu, ngenxa yoko abantu baneenkohliso, oko kukuthi, amandla asebenzayo njengamandla abonakalayo, abayaziyo amandla asebenzayo yinxalenye ye
Amandla abonakalayo, kunye nefomula: P = Scos θ = uicosθ = i-UIF. Apho p ngamandla asebenzayo kwi-W (ii-watts); F = cos θ ibizwa ngokuba yinto yamandla, kwaye θ yinxalenye yenqanaba lamajelo ahlukeneyo e-voltage kwindawo engafakwanga. Amandla asebenzayo yinxalenye yamandla agcinwe kwisekethe kodwa engasebenzi ngokuthe ngqo, eboniswe yifomula: Q = ssin θ = uisinθ. Apho i-q ngamandla aphindayo kwi-VAR (ukusilela).

KubaIintloko zentloko ezikhokelelaKwaye yonke enye imizuzwana ye-elektroniki esebenza kwi-DC Voltage, akunakwenzeka ukusebenza ngaphandle kwamandla.
