Have you ever wondered how the lights in your alarm clock work? Or have you ever considered how that tiny red light in your TV remote control sends a signal that helps you find your favorite show? What these and countless other bright devices have in common is a light-emitting diode, or LED. But how does an LED work? How is it different from other lightbulbs?
