LEDs (Light-Emitting Diodes) are widely used electronic components that emit light when an electric current passes through them. They are known for their high efficiency, low power consumption, long lifespan, and fast response time. LEDs are commonly used for indication, display, and illumination purposes in electronic circuits. Available in various colors, brightness levels, sizes, and package types such as through-hole and surface-mount LEDs, they are designed to operate at different forward voltages and current ratings. LEDs are extensively used in consumer electronics, automotive lighting, display panels, signage, industrial equipment, and communication devices, contributing to energy efficiency, reliability, and enhanced visual performance.
