1. Itekhnoloji ye-PWM eqhubekayo yangoku kunye nobushushu obuphantsi kunye nokuchaneka okuphezulu kwangoku.Ukunciphisa ilahleko yomgca, akukho ngcoliseko kwigridi yamandla.Umbane wamandla ngu-0.9, ukuphazamiseka kwe-harmonic yi-20%, kwaye i-EMI idibana nesalathisi sehlabathi jikelele, esinciphisa ukulahlekelwa kwamandla ombane kunye nokuphepha ukungcoliseka kokuphazamiseka kwe-high-frequency kwigridi yamandla.Intloko yesibane eqhelekileyo, inokutshintsha ngokuthe ngqo isibane se-halogen esikhoyo, isibane se-incandescent, isibane se-fluorescent.Ukukhanya okukhanyayo okukhanyayo kunokufikelela kwi-80 lm / w, iintlobo ezahlukeneyo zokushisa kombala wokukhanya kwe-LED ozikhethelayo, isalathisi esinikezela ngombala ophezulu, ukunikezelwa kombala okulungileyo.Ngokucacileyo, nje ukuba iindleko zezibane ze-LED ziyancipha ngeteknoloji ekhokelwayo.Izibane zokugcina amandla kunye nezibane ze-incandescent ngokuqinisekileyo ziya kutshintshwa zizibane ze-LED.Ummandla uhlawula ingqalelo ngakumbi nangakumbi ekukhanyiseni ukonga amandla kunye nemiba yokukhuselwa kwendalo, kwaye uye wakhuthaza ngamandla ukusetyenziswa kwezibane ze-LED.
2. Iqondo lokuboniswa kombala wento yomthombo wokukhanya kuthiwa ukusebenza kombala, oko kukuthi, iqondo lombala wokwenyani.Umthombo wokukhanya onombala ophezulu wombala unomsebenzi ongcono wombala, kwaye umbala esiwubonayo usondele kumbala wendalo kunye nokusebenza kombala Imithombo yokukhanya ephantsi yenza okubi kakhulu kwimibala, kwaye sibona ukuphambuka kwemibala emikhulu.Kutheni kunokubakho amanqaku aphezulu kunye nombala ophantsi wesondo?Isitshixo silele kwiimpawu ze-spectral zokukhanya, ubude be-wavelength bokukhanya okubonakalayo kuluhlu lwe-380nm ukuya kwi-780nm, esiyibona kwibala elibomvu, i-orenji, i-yellow, eluhlaza, eluhlaza, eluhlaza, eluhlaza, emfusa, ukuba ukukhanya ukukhanya kuqulethe umlinganiselo wokukhanya okumibalabala kunye nokukhanya kwendalo, umbala wamehlo ethu unokwenene ngakumbi.Kodwa abantu abasoloko besebenzisa izibane ze-LED baya kufumanisa ukuba i-LED ngenxa yokukhanya okukhulu ngakumbi, kulula ukwenza amandla okukhanya abe ngamandla obushushu, okwenza izibane ze-LED zishushu kakhulu.
Isibane se-fluorescent se-3.LED sisebenzisa iteknoloji entsha yomthombo wokukhanya we-LED, uyilo lwembonakalo yedijithali, ukonga amandla ngaphezu kwe-70%, i-12W ye-LED fluorescent intensity light ilingana ne-40W ityhubhu ye-fluorescent (ye-ballast kunye ne-starter, i-36W isibane se-fluorescent ukusetyenziswa kwamandla okwenene yi-42W ukuya kwi-44W ).Ubomi besibane se-fluorescent se-LED bungaphezu kwamaxesha angama-10 kwisibane esiqhelekileyo, phantse ukugcinwa kwamahhala, kwaye akukho mfuneko yokutshintsha isibane, i-ballast kunye ne-starter rhoqo.I-NASA yoMmandla isebenzisa izibane ze-LED kwindawo, ilandelwa yigadi yasekhaya kunye neyorhwebo yangaphakathi.Umthombo wokukhanya wombane we-semiconductor eluhlaza, ukukhanya okuthambileyo, i-spectrum ecocekileyo, ilungele ukhuseleko lombono kunye nempilo yomsebenzisi.
