Ukubuka konke
Isithiyo sokuphepha esihlukanisiwe esinomphumela we-transistor wokufaka iswishi, okuyinto ihlukanisa futhi idlulise izimpawu zokufaka ezivela koxhumana nabo beswishi noma ukusondela ishintsha ezindaweni eziyingozi iye endaweni yokuphepha nge-transistor yokukhipha ngokusebenzisa isithiyo sokuphepha. Ukutholwa kwephutha lomugqa kufezwa ngokusebenzisa I-LED phezulu kwemojuli. Kusetshenziswa iswishi yokudayela yemojuli ukusetha ukulawula kokufaka nokukhiphayo esigabeni noma emuva, kanye nokuvumela noma khubaza umsebenzi wokubonisa i-alamu yokuthola amaphutha emugqeni.
Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele, ngamandla ahlukanisiwe amatheminali okunikeza, okufakayo, kanye nokukhipha.

Ukutholwa Kwephutha Lomugqa (LFD)
Abasebenzisi bangakhetha uhlangothi oluthi "VULIWE" lweswishi phezulu kwemojuli ukuze kusebenze umsebenzi wokuthola amaphutha futhi kuboniswe i-alamu nge- isibani se-LED esibomvu. Ukufakwa kwamandla kagesi >7mA endaweni, i-alamu yesikhathi esifushane (SC); I-input current esendaweni
okokufaka kokuthintana kudinga umsebenzi wokuthola amaphutha (ukuphuka kwentambo, ukufinyela isekethe), i-resistor engu-22k Ω kufanele ixhunywe ngokuhambisana kuzo zombili izinhlangothi yeswishi, kanye ne-resistor engu-680 Ω kufanele kuxhunywe ngochungechunge (njengoba kuboniswe kumdwebo wocingo wokuxhumana kweswishi II).
