LEDdiods

LEDdiods, or Light Emitting Diodes, are semiconductor devices that emit light when an electric current passes through them. They are a type of diode, meaning they allow current to flow in only one direction. The color of the light emitted depends on the material used in the semiconductor. LEDs are known for their energy efficiency, long lifespan, and durability. They require less power than incandescent bulbs and produce less heat. Their compact size and versatility have led to widespread use in various applications.

Early LEDs produced red and green light. Over time, technological advancements enabled the creation of blue and white LEDs, significantly expanding their potential. White LEDs are often produced by combining red, green, and blue light-emitting diodes or by coating a blue LED with a phosphor material that converts some of the blue light into other colors. This ability to produce a wide spectrum of colors, along with their efficiency and longevity, has made LEDs the dominant lighting technology in many areas.

Applications of LEDdiods range from indicator lights on electronic devices to general illumination in homes and offices. They are also used in displays for televisions, smartphones, and digital signage. Their use in automotive lighting, traffic signals, and flashlights is also common. The development of high-power LEDs has further broadened their use in applications requiring bright illumination.
