A Light Emitting Diode (LED) is a semiconductor device that emits light when current flows through it. It is a type of diode that converts electrical energy into light energy. The LED symbol consists of an arrowhead pointing away from the device, indicating the direction of light emission. It is similar to a regular diode symbol with an additional arrowhead. LEDs are widely used in various applications such as lighting, displays, indicators, and electronic signage due to their low power consumption, long lifespan, and ability to emit light in different colors. They have become a popular choice for energy-efficient and environmentally-friendly lighting solutions.
