LED stands for Light-Emitting-Diode, which is capable of emitting light using semiconductor materials.
LEDs are very flexible, and there are many different types of LEDs in life such as LED strip lights, LED downlights, LED ceiling lights, LED floodlights, LED street lights...
LEDs are essentially semiconductor devices doped with impurities to create a PN junction, where the P channel contains holes and the N channel contains electrons. The movement of electrons inside the semiconductor material creates photons, which emit visible light.
Due to the structure of different semiconductors, light with different wavelengths is produced, that is, monochromatic light of different colors is produced.
For details on how LED lights work, please watch the video below.
Lighting is one of the most groundbreaking inventions in human history, starting with incandescent bulbs, fluorescent bulbs and now LED lights hold the leading position, providing both light and efficiency, changing the way people see the world.
Although the price of LED lights is higher than traditional lights, the durability is at least 10,000 hours equivalent to 4 years of use, the best energy saving currently is 5 times that of incandescent lights and 2 times that of compact bulbs, the luminous flux is brighter than other types of lights, high lighting efficiency, diverse color temperatures... so it is chosen by many users.
