Tugijuhtpinge on nt konstantne pinge, mille vooluallikas muundab LED-i sisselülitamise ajal lineaarselt vooluks, et pakkuda sõltumatut juhtimist iga LED-voolu üle.
The reference control voltage is a constant voltage that is converted by the current source linearly into current during the LED on-time. The purpose of the RCV is to provide independent control over each LED current.
