An LED Drive Circuit with Constant-Output-Current Control and Constant-Luminance Control
An LED Drive Circuit with Constant-Output-Current Control and Constant-Luminance Control, 2006 A Single LED is very small, and their luminance is related to the amount of driving current. Sufficient luminance for an illuminator requires many LEDs to be connected together and a constant current supplied to each LED. Therefore, the LED drive circuit must have constant-output-current control and/or constant-luminance control.
