Waa maxay Darawalka Dimmer-ka ee LED-ka?

Maadaama LED-yadu ay u baahan yihiin koronto toos ah iyo danab hoose si ay u shaqeeyaan, darawalka LED-ka waa in la hagaajiyaa si loo xakameeyo xaddiga korontada ee gala LED-ka.
Darawalka LED-ka waa qayb koronto oo nidaamisa danabka iyo hadda ka yimaada korontada si ay LED-yadu si ammaan ah oo wax ku ool ah ugu shaqeeyaan. Darawalka LED-ka wuxuu beddelaa sahayda hadda (AC) ee ka timaadda korontada una beddelaa hadda (DC) toos ah sababtoo ah inta badan sahayda korontada waxay ku shaqeeyaan korontada.
LED-ka waxaa laga dhigi karaa mid la qaboojin karo iyadoo la beddelayo darawalka LED-ka, kaas oo mas'uul ka ah nidaaminta xaddiga hadda ee gala LED-ka. Darawalka LED-ka ee la habeeyey, oo mararka qaarkood loogu yeero darawalka LED-ka ee dimmer-ka, wuxuu wax ka beddelaa iftiinka LED-ka.
Waa muhiim in la tixgeliyo fududaynta isticmaalka darawalka LED dimmer marka aad wax iibsanayso. Darawalka LED dimmer-ka oo leh laba xirmo oo khadka tooska ah (DIP) oo hore u furan ayaa u sahlaya dadka isticmaala inay beddelaan hadda wax soo saarka, taasoo iyaduna wax ka beddesha iftiinka LED-ka.
Waafaqsanaanta darawalka LED dimmer-ka oo leh saxannada derbiga ee Triode for Alternating Current (TRIAC) iyo korontada waa astaamo kale oo la hubin karo. Tani waxay damaanad qaadaysaa inaad nidaamin karto qulqulka korantada ee xawaaraha sare leh ee galaya LED-ka iyo in dimmer-kaagu uu u shaqayn doono mashruuc kasta oo aad maskaxda ku hayso.

Laba hab ama habayn ayaa darawalada LED dimmer-ka ay isticmaalaan si ay u xakameeyaan qulqulka korantada ee gala LED-ka: habaynta mugga iyo habaynta ballaca garaaca.

Yoolka ah in la yareeyo xaddiga korontada ee dhex marta LED-ka waa in la beddelo ballaca garaaca wadnaha, ama PWM.
Darawalka ayaa mar mar shida oo damiya korontada oo dib u shida si uu u xakameeyo xaddiga korontada ee ku shaqeeya LED-ka, xitaa haddii korontada soo gasha LED-ku ay joogto tahay. Natiijo ahaan is-weydaarsigan aadka u gaaban awgeed, nalalka ayaa noqda kuwo mugdi badan oo si dhakhso ah u libdhaya si aan la dareemi karin aragtida aadanuhu u aragto.

Yaraynta xaddiga korontada ee gelaysa LED-ka waxaa loo yaqaan modulation-ka weyn, ama AM. Iftiinka yaraaday wuxuu ka dhashaa isticmaalka tamar yar. Si la mid ah, hoos u dhaca hadda wuxuu keenaa heerkul hoose iyo waxtarka LED-ka oo kordha. Flicker-ka sidoo kale waa la baabi'iyaa iyadoo la adeegsanayo istaraatiijiyaddan.
Si kastaba ha ahaatee, maskaxda ku hay in isticmaalka habkan yareynta iftiinka uu leeyahay khatar ah inuu beddelo wax soo saarka midabka LED-ka, gaar ahaan heerarka hooseeya.

Helitaanka darawalada LED-ka ee la demi karo waxay kuu sahlaysaa inaad ka faa'iidaysato nalalkaaga LED-ka. Ka faa'iidayso xorriyadda aad ku beddeli karto heerarka dhalaalka ee LED-yadaada si aad u badbaadiso tamarta oo aad gurigaaga ugu hesho nalalka ugu raaxada badan.
