Semiconductor light emitting diodes (LEDs) have been widely used in indicator lights, signal lights, instrument displays, mobile phone backlights, vehicle-mounted light sources, and other occasions. White light LED technology is also constantly developing, and LEDs are increasingly widely used in the field of lighting. In the past, there were no comprehensive national and industry standards for LED testing, and in production practice, only relative parameters could be used as a basis. Different manufacturers, users, and research institutions had great disputes over this, which greatly affected the development of the domestic LED industry. Combined with the latest standards on LED testing methods at home and abroad, based on the actual needs of various LED application fields, this paper introduces the electrical characteristics, optical characteristics, switching characteristics, color characteristics, thermal characteristics, reliability, etc.
