LED (Light Emitting Diode, LED) is an abbreviation for LED, also known as LED, is a solid-state semiconductor device that directly converts electricity into light. This kind of semiconductor component has been generally used as an indicator light and a display panel. However, with the increase of technology, it has been used as a light source. It can directly convert electric energy into light energy with high efficiency, and has a maximum of tens of thousands of hours. ～100,000 hours of service life, not only the traditional light bulb is fragile, and can save electricity.
