  • Light-emitting diode - Wikipedia
    In electrical engineering, a light-emitting diode (LED) is a semiconductor device that emits light when current flows through it Electrons in the semiconductor recombine with electron holes, thereby releasing energy in the form of photons
  • LED | Definition, Light, Facts | Britannica
    An LED (light-emitting diode) is a semiconductor device that emits infrared or visible light when charged with an electric current
  • Learn About LED Lighting - ENERGY STAR
    LED stands for light emitting diode LED lighting products produce light up to 90% more efficiently than incandescent light bulbs How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light
  • Light Emitting Diode (LED): What is it How Does it Work?
    What is a Light Emitting Diode (LED)? A Light Emitting Diode (LED) is a special type of PN junction diode The light emitting diode is specially doped and made of a special type of semiconductor This diode can emit light when it is in the forward biased state
  • LED (Light-emitting diode) explained - Soldered Electronics
    The first question that might pop into your mind is, what is exactly an LED? A regular diode is a semiconductor device that works as a one-way switch for electrical current It allows current in only one direction and will stop it from flowing in the other An LED works the same way
  • Light Emitting Diode (LED): Principle, Advantages, and Uses
    A light-emitting diode (LED) is a small electronic device that emits light when an electric current flows through it LED works by passing electricity through a semiconductor, which releases energy in the form of light
  • LED - Light Emitting Diode: Basics, Types and Characteristics
    As mentioned in the introduction, an LED is a semiconductor light source It consists of a PN Junction Diode and when voltage is applied to the LED, electrons and holes recombine in the PN Junction and release energy in the form of light (Photons)
  • Amazon. com: Led Bulb
