Nalalka LED-kawaxay noqotay tignoolajiyada caadiga ah. Tooshka LED, nalalka taraafikku iyo laambadaha ayaa meel walba yaal.Wadamadu waxay kor u qaadayaan beddelka nalalka ifaya iyo kuwa dhaadheer ee guryaha, ganacsiga iyo codsiyada warshadaha ee ku shaqeeya awooda weyn ee nalalka LED.Si kastaba ha noqotee, haddii nalka LED uu yahay inuu beddelo nalalka iftiinka oo uu noqdo jirka ugu weyn ee goobta iftiinka, tignoolajiyada LED-ka ee silikoon la xakameeyey waxay noqon doontaa arrin muhiim ah.

Dimming waa tignoolajiyad aad muhiim u ah isha iftiinka.Sababtoo ah ma bixin karto oo kaliya jawi nalal raaxo leh, laakiin sidoo kale waxay gaari kartaa ilaalinta tamarta iyo dhimista qiiqa.Iyada oo kobaca degdega ah ee suuqa dalabka LED, baaxadda codsiga ee alaabada LED sidoo kale way sii socon doontaa inay koraan.Alaabooyinka LED-ku waa inay buuxiyaan baahiyaha deegaan codsiyo kala duwan, sidaa darteed shaqada xakamaynta dhalaalka LED sidoo kale waa lagama maarmaan.

Inkastoo ayNalalka LED-kaiyada oo aan la dhayalsaneyn weli suuqgeedii.Laakiin adeegsiga tignoolajiyada dimming LED kaliya ma hagaajin karto isbarbardhigga, laakiin sidoo kale waxay yaraynaysaa isticmaalka awoodda.Sidaa darteed, horumarinta tignoolajiyada dimming LED waa isbeddel lama huraan ah.Haddii LED rabto in ay xaqiiqsato dimming, sahayda korantadu waa in ay awood u leedahay in ay soo saaraan xagal isbeddel ah ee silikon kontoroolka ay gacanta ku, si ay u hagaajiyaan socodka joogtada ah ee LED ee hal jiho.Aad bay u adagtahay in tan la sameeyo iyadoo la ilaalinayo shaqada caadiga ah ee dimmer, taas oo inta badan keenta waxqabad xumo.Bilig bilig iyo iftiin aan sinnayn ayaa dhaca.

Iyaga oo wajahaya dhibaatooyinka iftiinka LED-ka, shirkadaha waaweyn ee warshadaha ayaa si tartiib tartiib ah u bartay tignoolajiyada iftiinka LED-yada tayada sare leh iyo xalalka.Marvell, oo ah hormuudka soo saaraha semiconductor-ka adduunka, ayaa bilaabay xalkeeda daciifinta LED-ka.Qorshahaan wuxuu ku saleysan yahay 88EM8183 waxaana loogu talagalay codsiyada nalalka LED-ka ee khadka tooska ah, kaasoo gaari kara ugu yaraan 1% dhumuc qotodheer.Sababtoo ah 88EM8183 waxay isticmaashaa hannaan kontorool oo aasaasiga ah oo u gaar ah, waxay ku guuleysan kartaa hagaajinta wax soo saarka aadka u adag ee kala duwanaanshaha AC-ga ee ballaaran.
