Marka ilo cusub oo iftiin ah uu soo galo suuqa, dhibaatada stroboscopic ayaa sidoo kale soo baxday. PNNL's Miller waxaan ku idhi: Baaxadda iftiinka iftiinka LED-ka ayaa xitaa ka weyn kan laambadda shidan ama laambada dhaadheer. Si kastaba ha ahaatee, si ka duwan HID ama nalalka dhaadheer, nalka adag SSL waa qalab DC ah, taas oo macnaheedu yahay in marka hadda joogto ah la keeno, LED waa la shidi karaa iyada oo aan flicker.
Wareegyada LED-yada fudud ee aan isticmaalin wadida hagaajinta joogtada ah ee joogtada ah ee goonida ah, iftiinka LED-ku wuxuu isku beddeli doonaa wareegga beddelka ee hadda. Darawalku wuxuu ka ciyaaraa laba door, koronto iyo hagaajin. Habka beddelka laga bilaabo wadista ilaa LED, beddelka hadda iyo hadda tooska ah ayaa soo saari doona koronto iyo wax soo saarka hadda. Ripple noocan oo kale ah ayaa ka jira laba jeer inta jeer ee korantada sahayda, taas oo ah 120H gudaha Mareykanka. Waxa jira xidhiidh u dhigma oo u dhexeeya wax-soo-saarka LED-ka iyo qaab-dhismeedka wax-soo-saarka wadista. Dimming waa sabab kale oo flicker ah. Dimmers-dhaqameedka, sida dimmers TRIAC (waa qayb elektaroonig ah oo qaban karta korantada laba-geesoodka ah), hagaajinta hadda oo yareeya iftiinka iftiinka adiga oo kordhinaya wakhtiga xidhitaanka inta lagu jiro wareegga beddelka. Nalalka LED-yada, waxa ay ku habboon tahay in la isticmaalo habaynta ballaca garaaca wadnaha (PWM) si loogu beddelo nalalka laydhka ee ka sarreeya 200 Hz. Si kastaba ha ahaatee, Benya wuxuu ku nuuxnuuxsaday: "Haddii aad isticmaasho habaynta ballaca garaaca garaaca ee soo noqnoqoshada aad u hooseeya, sida soo noqnoqda korontada caadiga ah, waxay keeni doontaa flicker aad u sarreeya."
Falanqaynta dareenka guud ee stroboscopic LED:
Waxaa jira afar fursadood oo keeni kara in isha iftiinka LED-ka uu shido ama damiyo.
1) Kuul nalka ED kuma dhigna sahayda korantada wadista LED, iyo 1W kuul ee caadiga ah waxa uu u adkaysanayaa hadda: 280-30mA.
Voltage: 3.0-3.4V, haddii chip laambad uusan lahayn awood ku filan, waxay keeni doontaa in isha iftiinka si lilig, iyo hadda waa mid aad u sarreeya.
Marka la helo, way shidaysaa oo dami doontaa. Xaalado halis ah, siliga dahabka ah ama siliga naxaasta ah ee lagu dhex dhisay laambada waa la gubi doonaa, taasoo keenaysa in laambaduhu aanu shidmin.
2) Waxaa dhici karta in korontadii wadista baabuurtu ay jabto, haddii lagu beddelo quwad kale oo wanaagsan, ma hilmaami doonto.
3) Haddii darawalku leeyahay shaqada ilaalinta heerkulka xad dhaafka ah, iyo waxqabadka kulaylka walaxda ee nalka aanu buuxin karin shuruudaha, ilaalinta heerkulka xad-dhaafka ah ee darawalku wuxuu bilaabmayaa.
Waxaa jiri doona ifafaale biligleynaya iyo ifafaale marka la shaqeynayo, tusaale ahaan: Guryaha 20W ee nalka daadka waxaa loo isticmaalaa in lagu soo ururiyo nalal 30W ah, ma jirto shaqo kuleyl ah. Waxay noqon doontaa sidan oo kale haddii la sameeyo.
4) Haddii nalka dibadda uu sidoo kale leeyahay ifafaale ah in uu shidan yahay oo daminayo, markaas laambada ayaa daadad doonta, natiijaduna waxay noqon doontaa mid ifaysa oo ma shidayso. Kuulka laambada iyo darawalka waa la jebin doonaa. Kaliya beddel isha iftiinka.
Sida loo yareeyo stroboscopic
Furaha yaraynta flicker stroboscopic waa wadista, kaas oo lagu xallin karo in la bixiyo joogto ah, aan buuq lahayn hadda. Si kastaba ha noqotee, soosaarayaashu waa inay miisaamaan arrimo kale si ay u kaxeeyaan qiimaha, cabbirka, isku halaynta iyo hufnaanta marka ay taageerayaan alaabada LED. Ree waxaa matalaya Mark McClear, madaxweyne ku xigeenka injineernimada. Isticmaalka loogu talagalay iftiinka iftiinka ayaa sidoo kale loo baahan yahay in la tixgeliyo si loo hubiyo in alaabtu aysan ahayn mid aad loo naqshadeeyey, sababtoo ah xaaladaha iftiinka qaarkood flicker stroboscopic waa mid la aqbali karo, qaarna maaha. Mcclear ayaa sidoo kale yiri: "Warshadeeyayaashu waxay isku dayeen inay hagaajiyaan alaabooyinka ku habboon codsiyada, iyo sida loo sameeyo strobe mid la aqbali karo iyada oo aan la kordhin qiimaha." Capacitors waxay hagaajin karaan ripple AC ee darawalka ilaa LED, laakiin sidoo kale waxay leedahay faa'iidooyin, Benya ayaa yidhi. Capacitors waa weyn oo xasaasi u ah kulaylka ". Sidaa darteed, meel kooban oo xaddidan, sida Ilaha iftiinka beddelka LED, isticmaalka capacitors ma shaqeeyo Mawjadaha sare ee ka badan dhowr kilohertz Tani waxay la mid tahay ballasts elektaroonik ah oo kaxeynaya nalalka fluorescent, laakiin inta u dhaxaysa darawalka iyo LED-ka ayaa ku dhow Had iyo jeer ma aha mid macquul ah." Benya ayaa yidhi. Si loo fududeeyo tijaabada iswaafajinta ee u dhaxaysa dimmers iyo matoorada iftiinka LED ee dimmable (matoorada iftiinka LED), EMA (Ururka Korontada / Warshadaha Qaranka) ayaa sii daayay NEMA SSL7A-2013 "Solid State Lighting SSL Wajiga Goynta Dimming : Iswaafajinta aasaasiga ah ", tani waa hage loogu talagalay naqshadeeyayaasha alaabta iyo soosaarayaasha. Ilaa inta dimmer iyo LED light engine ay la kulmaan heerka caadiga ah, waxay ku habboon yihiin Megan, maamulaha mashruuca farsamada ee NEMA, ayaa sheegay in heerkani yahay kan ugu horreeya ee warshadaha. waxaana saxiixay 24 warshadood oo waaweyn. Hadafka SSL7A waa in laga takhaluso tijaabada isku midka ah ee nalalka iyo dimmers. Waxa loo baahan yahay in xooga la saaro waa in heerkani uu quseeyo teknoolajiyada ka dib marka heerka la sii daayo. Sida la sheegay, heerku ma bixinayo hab lagu "go'aamiyo iswaafajinta alaabada hadda jirta ama matoorada iftiinka LED-ka ee lagu rakibay iyo dimmers-goynta wejiga".
