  • Light-emitting diode - Wikipedia
    A light-emitting diode (LED) is an electronic component that uses a semiconductor to emit 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
  • 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
  • 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
  • Amazon. com: Led Lights
    Amazon com: led lights The ClimatePartner certified product label confirms that a product meets the requirements for the five steps in climate action including calculating carbon footprints, setting reduction targets, implementing reductions, financing climate projects and communicating transparently to continuously reducing emissions
  • 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 Lighting - Department of Energy
    The light-emitting diode (LED) is today's most energy-efficient and rapidly developing lighting technology Quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other types of lighting
