LED display, LED lighting, prolighting lamp (English: LED lamp) refers to the lamp that uses light emitting diode (LED) as the light source, generally made of semiconductor LED. The service life and luminous efficiency of LED lamps can reach several times of that of incandescent lamps, which is also much higher than that of integrated fluorescent lamps. The brightness of a single LED is much lower than that of traditional incandescent lamps and CFLs, so a bulb usually contains multiple LEDs. In recent years, with the improvement of diode technology, high-power and high-luminosity light-emitting diodes have been listed in succession, making this type of light bulb gradually replace other traditional light sources
