LED tsav fais fab mov yog lub zog hloov hluav taws xob uas hloov cov khoom siv hluav taws xob rau hauv qhov tshwj xeeb voltage thiab tam sim no los tsav lub LED kom tawm lub teeb.Raws li ib txwm muaj: lub tswv yim ntawm LED tsav lub zog muaj xws li high-voltage fais fab zaus AC (ie lub nroog fais fab), low-voltage DC, high-voltage DC, low-voltage and high-voltage.Zaus AC (xws li cov zis ntawm lub tshuab hluav taws xob hluav taws xob), thiab lwm yam.

- Raws li txoj kev tsav tsheb:

(1) Hom tam sim no tsis tu ncua

ib.Cov zis tam sim no ntawm cov tsav tam sim no tsis tu ncua, tab sis qhov tso zis DC voltage sib txawv nyob rau hauv ib qho kev sib txawv nrog qhov loj ntawm cov khoom ua haujlwm.Qhov me dua qhov load kuj, qhov tso zis voltage qis dua.Qhov loj dua qhov load tsis kam, qhov tso zis ntau dua qhov voltage;

b.Lub Circuit Court tam sim no tsis ntshai ntawm kev thauj khoom luv luv, tab sis nws yog nruj me ntsis txwv tsis pub qhib lub load tag nrho.

c.Nws yog qhov zoo tshaj plaws rau kev tsav tsheb tam sim no kom tsav LEDs, tab sis tus nqi kuj tseem siab.

d.Them mloog mus rau qhov siab tshaj plaws tiv taus tam sim no thiab voltage siv, uas txwv cov LEDs siv;

(2) Regulated hom:

ib.Thaum qhov ntau yam tsis sib xws hauv qhov hluav taws xob tswj hluav taws xob tau txiav txim siab, qhov tso zis hluav taws xob yog tsau, tab sis cov zis tam sim no hloov nrog qhov nce lossis txo qis ntawm qhov load;

b.Lub voltage regulator Circuit Court tsis ntshai ntawm load qhib, tab sis nws yog nruj me ntsis txwv tsis pub rau luv luv-circuit lub load tag nrho.

c.Lub LED yog tsav los ntawm ib tug voltage-stabilizing tsav Circuit Court, thiab txhua txoj hlua yuav tsum tau ntxiv nrog ib tug haum tsis kam ua rau txhua txoj hlua ntawm LEDs qhia ib tug nruab nrab brightness;

d.Qhov ci ntsa iab yuav cuam tshuam los ntawm kev hloov hluav taws xob los ntawm kev hloov kho.

- Kev faib tawm ntawm LED tsav lub zog:

(3) Pulse tsav

Ntau daim ntawv thov LED xav tau kev ua haujlwm dimming, xws liLED backlightlos yog architectural teeb pom kev dimming.Lub dimming muaj nuj nqi tuaj yeem pom tau los ntawm kev kho qhov ci thiab qhov sib txawv ntawm LED.Tsuas yog txo qhov tam sim no ntawm lub cuab yeej tuaj yeem kho tauLED teebemission, tab sis cia lub LED ua hauj lwm nyob rau hauv cov xwm txheej ntawm qis dua qhov ntsuas tam sim no yuav ua rau muaj ntau yam tsis zoo, xws li chromatic aberration.Lwm txoj hauv kev rau kev hloov kho tam sim no yooj yim yog kev sib koom ua ke ntawm pulse width modulation (PWM) maub los hauv LED tsav tsheb.Lub teeb liab PWM tsis yog siv ncaj qha los tswj lub LED, tab sis los tswj kev hloov pauv, xws li MOSFET, los muab qhov xav tau tam sim no rau LED.PWM maub los feem ntau ua haujlwm ntawm lub sijhawm ruaj khov thiab kho cov mem tes dav kom haum rau lub voj voog uas yuav tsum tau ua.Feem ntau cov chips LED tam sim no siv PWM los tswj LED lub teeb emission.Txhawm rau kom ntseeg tau tias tib neeg yuav tsis hnov ​​​​qhov pom tseeb flicker, qhov zaus ntawm PWM mem tes yuav tsum siab dua 100HZ.Lub ntsiab kom zoo dua ntawm PWM tswj yog tias qhov dimming tam sim no los ntawm PWM yog qhov tseeb dua, uas txo cov xim sib txawv thaum lub LED tawm lub teeb.

(4) AC tsav

Raws li kev siv sib txawv, AC tsav kuj tuaj yeem muab faib ua peb hom: phaw, txhawb zog, thiab hloov pauv.Qhov sib txawv ntawm AC tsav thiab DC tsav, ntxiv rau qhov yuav tsum tau kho thiab lim cov tswv yim AC, kuj tseem muaj teeb meem ntawm kev sib cais thiab tsis yog kev sib cais los ntawm qhov kev pom kev nyab xeeb.

AC input tsav tsheb feem ntau yog siv rau retrofit teeb: rau kaum PAR (Parabolic Aluminium Reflector, ib qho teeb pom kev zoo ntawm kev ua haujlwm theem) teeb, cov teeb pom kev zoo, thiab lwm yam, lawv ua haujlwm ntawm 100V, 120V lossis 230V AC Rau MR16 teeb, nws xav tau ua hauj lwm nyob rau hauv 12V AC input.Vim muaj qee qhov teeb meem nyuaj, xws li lub peev xwm dimming ntawm tus qauv triac lossis ua ntug thiab trailing ntug dimmers, thiab kev sib raug zoo nrog cov hluav taws xob hloov hluav taws xob (los ntawm AC kab hluav taws xob los tsim 12V AC rau MR16 teeb ua haujlwm) Qhov teeb meem ntawm kev ua tau zoo (uas yog, flicker -dawb ua haujlwm), yog li ntawd, piv nrog DC input tsav tsheb, thaj chaw koom nrog AC input tsav tsheb yog qhov nyuaj dua.

AC fais fab mov (tseem ceeb tsav) yog siv rau LED tsav, feem ntau los ntawm cov kauj ruam xws li kauj ruam-down, rectification, filtering, voltage stabilization (los yog tam sim no stabilization), thiab lwm yam, los hloov AC zog rau DC zog, thiab ces muab cov LEDs tsim nyog. los ntawm ib tug tsim nyog tsav Circuit Court Kev ua hauj lwm tam sim no yuav tsum muaj siab conversion efficiency, me me thiab tsawg tus nqi, thiab nyob rau tib lub sij hawm daws tau qhov teeb meem ntawm kev ruaj ntseg cais.Txhawm rau txiav txim siab qhov cuam tshuam ntawm daim phiaj hluav taws xob, qhov cuam tshuam ntawm electromagnetic cuam tshuam thiab cov teeb meem ntawm lub zog yuav tsum tau daws.Rau qis- thiab nruab nrab-lub zog LEDs, qhov zoo tshaj plaws Circuit Court qauv yog ib qho kev sib cais ib leeg-kawg ya rov qab converter circuit;rau kev siv hluav taws xob siab, yuav tsum siv lub tshuab hluav taws xob txuas txuas.

-Power installation qhov chaw faib faib:

Tsav lub zog tuaj yeem muab faib ua cov khoom siv hluav taws xob sab nraud thiab cov khoom siv hluav taws xob ua haujlwm raws li qhov chaw teeb tsa.

(1) Sab nraud fais fab mov

Raws li lub npe qhia, cov khoom siv hluav taws xob sab nraud yog los nruab lub zog hluav taws xob sab nraud.Feem ntau, qhov hluav taws xob yog qhov siab, uas yog kev nyab xeeb rau tib neeg, thiab yuav tsum muaj hluav taws xob sab nraud.Qhov sib txawv nrog cov khoom siv hluav taws xob built-in yog tias cov khoom siv hluav taws xob muaj lub plhaub, thiab cov teeb pom kev zoo yog cov khoom siv.

(2) Built-in fais fab mov

Lub hwj huam mov yog ntsia rau hauv lub teeb.Feem ntau, qhov hluav taws xob tsawg, los ntawm 12v rau 24v, uas tsis muaj kev nyab xeeb rau tib neeg.Hom no muaj teeb pom kev zoo.
