Taabo nalka miiska LED-ka ee sii yaraanaya
Mabda'a dimmer LED
Dimmer LED waa qayb muhiim ah oo ka mid ah nalalka casriga ah, waa iyada oo la hagaajinayo xajmiga korantada korontada, si loo hagaajiyo iftiinka nalalka LED.Iyadoo horumarinta joogtada ah iyo hagaajinta tignoolajiyada iftiinka LED-ka, nalalka LED-ku waxay noqdeen alaabooyinka caadiga ah ee gudaha gudaha iyo dibaddaba, sidaas darteed isticmaalka dimmers LED ayaa soo bandhigay shuruudo sare.Maqaalkani wuxuu soo bandhigi doonaa mabda'a dimmer LED iyo sida ay ula shaqeyso nalalka LED si loo fahmo oo loo isticmaalo qalabkan.
Mabda'a dimmer LED
Mabda'a dimmer LED waa in la beddelo dhalaalka wax soo saarka iyadoo la hagaajinayo korantada korontada DC ee nalka.Maadaama nalka LED-ku uu yahay il toos ah oo hadda ku shaqeeya, waxaa lagama maarmaan ah in la beddelo tamarta korontada ee hadda jirta inta lagu jiro isticmaalka si loo xakameeyo dhalaalka isha iftiinka LED.
Wareega eeNalalka LED-kawaxaa ka mid ah saddex qaybood oo xudun u ah, kuwaas oo kala ah koronto, il joogto ah iyo isha iftiinka LED laftiisa.Korontadu waxay bixisaa danab u dhigma si ay u kaxeyso isha iftiinka LED, halka isha joogtada ah ee hadda jirta ay hubiso xasilloonida isha iftiinka LED iyadoo la ilaalinayo socodka hadda ee LED-ka oo aan isbeddelin.Sidaa darteed, shaqada ugu weyn ee dimmer waa in la hagaajiyo tamarta korontada, taas oo saameynaysa iftiinka iftiinka iftiinka LED.Dimmer guud ahaan iyada oo loo marayo seddex qaab si loo gaaro nidaaminta korantada korantada LED: modulation PWM, modulation volta iyo modulation joogto ah.
1. Habaynta PWM
Hababka PWM waa mid ka mid ah hababka nidaaminta dimmer ee inta badan la isticmaalo.Habka hagaajinta ayaa damisa danabka sahayda korantada wakhti go'an wuxuuna xakameynayaa saamiga shaqada ee danabka sahayda korantada ee wareeg kasta, taas oo saameynaysa dhalaalka nalka LED.Dimming firfircoon waxaa lagu gaari karaa iyada oo loo marayo habaynta PWM, iyo sidoo kale in la daboolo baahiyaha iftiinka kala duwan.
2. Habka wada shaqayneed ee u dhexeeyaDimmer LED iyo iftiinka LED
Habka wada shaqayneed ee u dhexeeya dimmer LED iyo iftiinka LED waa in la xaqiijiyo hagaajinta dhalaalka iftiinka LED iyada oo la adeegsanayo isdhexgalka.Kuwa soo socdaa waa hordhac kooban oo ku saabsan isdhexgalka ka dhexeeya dimmer LED iyo iftiinka LED.
1. Habaynta PWM
Qaabka qaabaynta PWM, dhalaalka iftiinka iftiinka LED waxaa lagu xakameynayaa hagaajinta wareegga waajibaadka korantada sahayda korontada.Dimmer-ku wuxuu u gudbiyaa calaamadda hagaajinta iftiinka LED-ka, iyo iftiinka LED-ku wuxuu soo saaraa iftiin kala duwan iyadoo loo eegayo dhalaalka kala duwan ee calaamadda hagaajinta.Calaamadaha hagaajinta ee u dhexeeya labadooda badanaa waxay ku salaysan yihiin signalka dhijitaalka ah, kaas oo xaqiijin kara kontoroolka fog iyo hoos u dhaca.
2. Hababka korantada
Qaabka qaabaynta korantada, dimmer-ga LED-ku wuxuu maamulaa nalka LED-ka isagoo kaxeynaya wax soo saarka iftiinka LED-ka.
Laambada miiska LED-ka ee dib-u-cusbooneysii karo - Hooska dhayalsan
SHARAXA GAABAN:
Hooska rafaadka ah ee la jeexjeexay, dib la buuxin karonalka miiska.Ku dar taabashada xarrago meel kasta oo leh nalkan gaarka ah oo leh hadh quruxsan oo la taaban karo.Iyada oo ku dhex dhisan baytari dib lagu dallaci karo, waxaad ku raaxaysan kartaa la qaadi karonalalka wirelessiyada oo aan dhibka fiilooyinka.Hooska isku laabma waxay isku daraan shaqeynta, qurxinta iyo raaxada, iyaga oo ka dhigaya l qummanxal-qaboojin fama qaab nololeedka casriga ah.
