LED is the acronym for light-emitting diode (Light Emitting Diode), it is the use of solid semiconductor chip as luminescent materials, red, yellow, blue, white and other colors of light to get through photon emission. LED has been widely used in decorative lighting, urban landscape lighting, large screen display, automotive lamps, general lighting field. LED's energy consumption is only one tenth of incandescent,but the life is 100 times of incandescent , known as "the revolutionary technology of the 21st century, a new era of solid-state light source".
View of the LED lighting technology has become more sophisticated in recent years, the United States, Japan, the European Union and other developed countries have developed standard on the LED security, performance, energy efficiency requirements to be standardized.
The United States is the one of the global LED industry most developed areas. U.S. National Electrical Manufacturers Association (NEMA) and the American National Standard Lighting Group (ANSLG) jointly issued on solid-state lighting products chroma specification ANSI C78.377-2008, the standard has been approved as an American National Standard;
Japan has the strongest global LED technology, holds most of the high-end market. LED lighting products to enter the Japanese market, the first to meet the requirements of the Electrical Appliance and Material Safety Law "and its implementing regulations. LED external power supply, the need to be detected according to J61347-2-13, and affix PSE Mark. Electromagnetic compatibility, will have to meet the the J55015 standard.
EU imports of LED products requiring the highest quality in the region. LED products entering the EU market, must comply with the safety requirements of the Low Voltage Directive, EMC electromagnetic compatibility requirements of the Directive, RoHS and WEEE environmental requirements, and ErP directive energy efficiency requirements. In addition, LED products is also subject to conformity assessment procedures prescribed by the appropriate regulations, the only way to affix the CE mark to a smooth entry into the European Union market.
