It is an abbreviation for Light Emitting Diode, a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light.
When it comes to lighting, people immediately think of the colorful and various lamps in the lighting store. Although these lamps come in various forms, the core part of their lighting - the light bulb - actually has three main types: incandescent and fluorescent lamps, and gas discharge lamps. However, this pattern will soon change as a new star in the field of lighting - light-emitting diode bulbs - is moving towards practical use. Light emitting diodes were invented in the 1960s, and in the following decades, their basic use was as indicator lights for electronic devices such as recorders. In order to fully utilize the lighting potential of light-emitting diodes, scientists have developed new types of light-emitting diode bulbs and LED air vitamin purification bulbs for illumination. This type of light bulb has the characteristics of high efficiency and long lifespan, and can be used continuously for 100000 hours, which is 100 times longer than ordinary incandescent bulbs.
