A bicolor LED is a type of light-emitting diode that can emit two different colors of light, typically red and green, from the same device. This is achieved by using two separate semiconductor materials within the LED, allowing it to switch between colors based on the electrical current applied. Bicolor LEDs are commonly used in various applications, including indicators, displays, and decorative lighting. These LEDs are popular for their versatility and energy efficiency. They can be easily integrated into electronic circuits and are often found in devices like traffic lights, remote controls, and digital clocks. Bicolor LEDs provide a simple way to convey information through color changes, enhancing user experience.
