Umphumela wamandla ku-headlamp ye-LED

I-Power Factor iyipharamitha ebalulekile yamalambu aholwayo, akunandabaIzibani eziholwa kabusha eziholayonoma izibani ezomile ezihoxisiwe. Ngakho-ke ake siqonde ukuqhubeka nokuthi yiliphi isici samandla.

1, amandla
Isici samandla sibonisa amandla weI-Headlamp ye-LEDukukhipha amandla asebenzayo. Amandla isilinganiso samanani okuhambisa amandla, futhi ku-DC Circuits Kungumkhiqizo weVoltage v futhi yamanje a.ins a.ins a.ins a.ins a.ins a.ins a.ins a.ins a. Umehluko phakathi kwamandla abonakalayo namandla angempela kuholela ekubusweni kwamandla, futhi isici samandla silingana nesilinganiso samandla angempela okubonisa amandla angempela. Ngakho-ke amandla wangempela ohlelweni lwe-AC alingana nezikhathi zamandla athembele ku-Power Factor.
Lokho kungukuthi: I-Power Factor = Amandla angempela / asobala. Isici samandla kuphela somthwalo oqondile onjenge-heater kagesi kanye nesibani esikhanyayo singu-1. Umehluko phakathi kwamandla uqobo futhi amandla asobala wemishini eminingi mncane kakhulu futhi anganakwa, ngenkathi umehluko phakathi kwemishini ye-capacive kanjena.

2, amandla abonakalayo
Amandla asebenzayo: Umkhiqizo we-AC Votage ne-AC yamanje. Ngefomula njenge: S = UI. Lapho amandla alinganiswe khona ku-VA (Volt-Ampere); Ulinganiselwa amandla okukhishwa ku-V, njenge-220V, 380V, njll; Ngilinganiselwa okukhiqizwayo kwamanje ku-A. Amandla asobala aqukethe izingxenye ezimbili: amandla asebenzayo (p) namandla asebenzayo (Q). Amandla asebenzayo asho ingxenye yomsebenzi owenziwe ngqo. Isibonelo, ukukhanya phezulu, ukujikeleza kwezimoto, ukujikeleza kwe-elekthronikhi. Ngoba la mandla sephendukile, angazizwa ngokuqondile ngabantu, ngakho-ke abanye abantu banokukhohlisa, okungukuthi, amandla asebenzayo njengamandla abonakalayo, owaziyo amandla asebenzayo kuphela
Amandla abonakalayo, ngefomula: p = scos θ = Uicosθ = UIF. Lapho p kungamandla asebenzayo ku-W (Watts); F = COS θ ibizwa ngokuthi yi-Power Factor, futhi θ ngukuhlukahluka kwesigaba se-Voltage Currents ehlukile emthwalweni ongaqondile. Amandla asebenzayo yingxenye yamandla agcinwe kwisifunda kodwa awasebenzi ngqo, avezwe yifomula: Q = ssin θ = Uisinθ. Lapho u-q unamandla okuvuselelwa ku-var (ukuntuleka).

IngomaneAma-headlamp e-LEDFuthi yonke eminye imibuthano kagesi esebenza kumandla kagesi we-DC, akunakwenzeka ukusebenza ngaphandle kwamandla.
