LED light structure

2024-11-13

What are LED lights? LED (Light Emitting Diode) light is a light emitting diode, an electronic device that converts electrical energy into light energy. How LED Lights Work LED lights work on the principle of light emission based on semiconductor materials. When a current is passed through a PN junction, forward injected electrons and holes located in the active layer of the PN junction compound to release energy. This energy is emitted in the form of light. In semiconductors, they release excess energy through carrier complexes, resulting in the emission of photons that directly emit red, yellow, blue, and green light. Based on this, any color of light can be emitted by adding phosphors using the trichromatic principle. Depending on the material and material structure, the color, brightness and power of LED light may vary. Commonly used in wall lights, street lights and other fields...
