Cov nyhuv ntawm lub zog ntawm LED Headlamps

Lub zog hluav taws xob yog qhov tseem ceeb ntawm LED teeb, tsis muaj teeb meemRechargeable LED teeblossis qhuav LED teeb. Yog li cia peb nkag siab ntxiv dab tsi muaj hwj chim yam.

1, lub zog
Lub zog muaj hwj chim cov xeeb ceem muaj peev xwm ntawm lubLED Prewlampkom tsim tawm lub zog nquag. Lub hwj chim yog kev ntsuas ntawm tus nqi sib kis ntawm lub zog, thiab hauv DC voj voog nws yog cov khoom lag luam ntawm voltage, uas yog cov khoom siv tam sim no, uas yog hu ua ree reetance lossis harmonic tam sim no, uas ua rau lub zog pom tseeb (hluav taws xob volt los ntawm amps tam sim no) ntau dua lub zog tiag tiag. Qhov sib txawv ntawm cov zog pom tseeb thiab lub zog muaj zog tiag tiag ua rau lub zog siv hluav taws xob, thiab lub zog muaj zog yog sib npaug ntawm qhov tseeb ntawm lub zog. Yog li lub zog tiag tiag hauv lub AC system yog sib npaug rau lub zog ntawm lub zog lub zog lub zog muaj zog.
Qhov ntawd yog: Lub Zog Hluav Taws Xob = Lub Zog Hluav Taws Xob / Pom Zoo. Tsuas yog lub zog siv hluav taws xob ntawm cov kab thauj khoom xws li cov khoom siv hluav taws xob ntau thiab tsis pom zoo ntawm cov khoom siv hluav taws xob ntau li cov teeb ci ntsa iab xws li cov teeb loj heev thiab tseem ceeb Cov.

2, Lub Zog Hluav Taws Xob
Lub zog nquag: Cov khoom ntawm AC Voltage thiab AC tam sim no. Nrog cov mis raws li: s = UI. Qhov twg s U yog cov zis nkag voltage hauv v, xws li 220V, 380V, thiab lwm yam .; Kuv yog cov tso zis tso tawm tam sim no hauv A. Lub zog pom tseeb muaj ob ntu: lub zog (p) thiab cov zog (Q). Lub zog nquag hais txog cov haujlwm ua ncaj qha. Piv txwv li, lub teeb ci, kev sib hloov kev sib hloov, hluav taws xob hauv hluav taws xob ua haujlwm. Vim tias lub hwj chim no tau ua cua sov, tuaj yeem ncaj ncees los ntawm tib neeg, yog li qee tus neeg muaj lub zog tseem ceeb, uas paub txog lub zog nquag tsuas yog ib feem ntawm
Lub zog pom zoo, nrog cov qauv: p = scos θ = UiFOSθ = UIF. Qhov twg p yog lub zog nquag hauv w (watts); F = cos θ yog hu ua lub zog muaj zog, thiab θ yog theem sib txawv ntawm cov sib txawv sib txawv ntawm cov loadinear. Reflective zog yog ib feem ntawm lub zog khaws cia hauv Circuit Coursed hauv Circuit Cours tab sis tsis ncaj qha ua haujlwm, tshaj tawm los ntawm cov qauv: Q = SSIN θ = UISINθ. Qhov twg q yog cov fais fab tuag hauv var (tsis muaj).

RauLED HeadlampsThiab tag nrho lwm cov hluav taws xob hluav taws xob uas ua haujlwm ntawm DC voltage, nws tsis yooj yim sua ua haujlwm yam tsis muaj hwj chim.
