Tasirin wutar lantarki akan fitilun LED

Power factor muhimmin siga ne na fitilun LED, komai girmansu.Fitilun LED masu cajiko kuma fitilun LED masu bushewa. Don haka bari mu ƙara fahimtar menene ƙarfin lantarki.

1, Ƙarfi
Ƙarfin iko yana nuna ikonFitilar LED mai kaidon fitar da wutar lantarki mai aiki. Wutar lantarki ma'auni ne na yawan watsa makamashi, kuma a cikin da'irori na DC shine samfurin ƙarfin lantarki V da na yanzu A. A cikin tsarin AC, ya fi rikitarwa: wasu wutar lantarki ta AC suna zagayawa a cikin kaya, wanda ake kira reactance current ko harmonic current, wanda ke sa wutar lantarki da aka bayyana (voltage Volt ta current Amps) ta fi ƙarfin gaske. Bambanci tsakanin wutar lantarki da aka bayyana da ainihin wutar lantarki yana kaiwa ga ƙarfin lantarki, kuma wutar lantarki tana daidai da rabon wutar lantarki da aka bayyana. Don haka ainihin wutar lantarki a cikin tsarin AC daidai yake da lokacin wutar lantarki da aka dogara da ita.
Wato: ƙarfin lantarki = ainihin ƙarfi / ƙarfin da ake iya gani. Sai dai ƙarfin da ke cikin nauyin layi kamar na'urar dumama wutar lantarki da kwan fitila shine 1. Bambancin da ke tsakanin ainihin ƙarfin da ƙarfin da ake iya gani na kayan aiki da yawa ƙanana ne kuma ba shi da yawa, yayin da bambancin da ke tsakanin kayan aiki masu ƙarfin lantarki kamar fitilu yana da girma sosai kuma yana da mahimmanci.

2, Ƙarfin da ke bayyana
Ƙarfin aiki: samfurin ƙarfin lantarki na AC da wutar AC. Tare da dabarar kamar haka: S=UI. Inda aka kimanta ƙarfin fitarwa na S a cikin VA (volt-ampere); ana kimanta ƙarfin fitarwa na U a cikin V, kamar 220V, 380V, da sauransu; I ana kimanta ƙarfin fitarwa na A a cikin A. Ƙarfin da ke bayyane ya ƙunshi sassa biyu: ƙarfin aiki (P) da ƙarfin amsawa (Q). Ƙarfin aiki yana nufin ɓangaren aikin da aka yi kai tsaye. Misali, hasken, juyawar motar, da'irar lantarki tana aiki. Saboda wannan ƙarfin ya zama zafi, mutane za su iya ji kai tsaye, don haka wasu mutane suna da ruɗani, wato, ƙarfin aiki a matsayin ƙarfin da ke bayyane, wanda ya san ƙarfin aiki wani ɓangare ne kawai na
Ƙarfin da aka bayyana, tare da dabarar: P = Scos θ = UIcosθ = UIF. Inda P shine ƙarfin aiki a cikin W (watts); F=cos θ ana kiransa da ƙarfin lantarki, kuma θ shine bambancin lokaci na kwararar wutar lantarki daban-daban a cikin nauyin da ba na layi ba. Ƙarfin amsawa shine ɓangaren wutar da aka adana a cikin da'irar amma ba a yi aiki kai tsaye ba, wanda dabarar ta bayyana: Q = Ssin θ = UIsinθ. Inda Q shine ƙarfin amsawa a cikin var (rashin).
