"Kwingingqi yaseAsia, apho izithuthi ezinamavili ama-2 zezona ndlela zokuhambisa uninzi, abenzi bezithuthi abaninzi bafuna ulungelelwaniso lwesekethe olulula lokuqhuba ngasemva kunye nezibane zepleyiti zelayisensi," ngokukaRohm. "Nangona kunjalo, ukuza kuthi ga ngoku imiba yoyilo olushushu yenze ukuba kube nzima kubaqhubi be-LED ukuba ii-LED zamandla ukuhlangabezana nazo zonke iimfuno ezahlukeneyo ngokwenani lezibane, ukukhanya, ukhuseleko kunye neendleko."
Emva kokuhlalutya eyona ntengiso inkulu yezithuthi ezinamavili amabini, eIndiya, inkampani igqibe kwelokuba abaqhubi bamashaneli abane bavelise i-150mA / ijelo, kunye nohlengahlengiso lwangoku lwejelo ngalinye, kwiphakheji ye-16pin.
Iziphumo kwaba:
I-BD18337EFV-M yokuqhuba umtya ophakamileyo weentambo ezintathu ze-LED
I-BD18347EFV-M yokuqhuba iintambo ezimbini eziphakamileyo zee-LED.
I-chip iza iphakheji ye-5x6mm gull-wing enephedi yokufudumeza ngaphantsi.
Abalawuli bangoku abangaphakathi bahlala bebandakanyiwe kwaye, ukunciphisa ukusasaza kobushushu kumgangatho ophakamileyo wangoku, kunokwenzeka ukubeka isichaso kuthotho kunye ne-LED nganye eyomeleleyo ukunceda ukwabelana ngokuhla kwamandla ombane phakathi kukaloliwe wombane kunye nomphezulu womtya. Kwakhona, nangona kunjalo, iRohm ibonelele ngepini eyahlukileyo (iVinRes) kunye nesekethe yolawulo lwangaphakathi ukuvumela zonke ezi zinto zixhathisiweyo ukuba zidityaniswe zibe yindibaniselwano ethile kaloliwe, ukubala kwe-LED kunye nokukhoyo ngoku.
Ukufunyanwa kwesiphoso kunye nokukhuselwa kubandakanya: i-LED evulekileyo, isekethe emfutshane, i-voltage ephezulu kunye nobushushu. Xa iimeko ezininzi zale chip zisetyenziselwa ukulawula ukukhanya kwisithuthi esinye, ibheyikhini enye phakathi kweetshipsi ivumela imeko yesiphoso ukuba kwabelwane ngayo kwaye kuthathwe amanyathelo ngayo.
"Ukuba isibane esingasemva asikhanyisi, abayili banokukhetha ukucima zonke izibane okanye umtya osileleyo kuphela," utshilo uRohm. "Ngenxa yemigangatho yokhuseleko lwezibane zepleyiti ezinelayisensi enamavili amabini xa kukho into engaqhelekanga eyahluka ngokwamazwe, olu luhlu lwamva nje lwenza ukuba kuthotyelwe imithetho emininzi yommandla ngesimo esinye."
Izicelo kulindeleke ukuba zibe zezi: izibane zangasemva (isitopu / umsila), izibane zenkungu, izikhombisi zomqondiso wokujika, izibane zepleyiti yenombolo kunye nezibane ezisebenza emini.
