Description

• A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. Here’s a brief overview:
• Working Principle: LEDs operate based on electroluminescence, where electrons recombine with electron holes within the semiconductor material, releasing energy in the form of photons (light)
• Materials: Common materials used in LEDs include gallium arsenide, aluminum gallium arsenide, and aluminum gallium indium phosphide. These materials determine the color of the emitted light
  Applications: LEDs are widely used in various applications such as indicator lamps, car brake lights, remote controls, displays, and general lighting
• Advantages: LEDs offer several benefits over traditional incandescent bulbs, including lower power consumption, longer lifespan, improved durability, smaller size, and faster switching
• Limitations: Some limitations include the need for low voltage and DC power, and a lower maximum operating temperature compared to other light sources
