This article describes simple constant current driver module with fast PWM input that can be used for driving medium and high power LEDs. The module uses an integrated constant-current output, DC-DC ...
Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...
A typical LCD consists of liquid crystal material with transparent electrodes and polarizing filters. Applying voltage across the liquid crystal layer allows light to pass through in varying amounts.
