LEDs

Definition

LEDs, or Light Emitting Diodes, are semiconductor devices that emit light when an electric current passes through them. They are widely used in video art for their efficiency, versatility, and ability to create various lighting effects that can enhance visual storytelling. With the capacity for color mixing and dimming, LEDs provide artists with dynamic tools to experiment with light in innovative ways.
