LED International standards

LED developed countries in order to seize the initiative, the LED standards and testing have invested a great deal of manpower and resources to focus on selected LED in the standards and test methods of parameters. Meanwhile, many foreign companies in research and development personnel are actively involved in national and international professional organizations, to develop semiconductor lighting test. For example, in the past the United States and Japan Lumileds Nichia announced that the two sides had their own LED technology cross-licensing and joint development of power type LED for standards to promote the market applications.

LED lighting standards and Detection Techniques International Commission on Illumination (CIE) and International Electrotechnical Commission (IEC) have no information on LED lighting standards. Strictly speaking, there is no specifically named foreign semiconductor lighting standards, only the testing standards of the ordinary and the LED light source with the general standards of lighting. General LED test standards:
1.IEC60747-5 Semiconductor devices Discrete devices and integrated circuits (1992)
IEC60747-5 discrete semiconductor devices and integrated circuits
2.IEC60747-5-2 Discrete semiconductor devices and integrated circuits-Part 5-2: OptoELectronic devices-Essential ratings and characteristics (1997-09)
IEC60747-5-2 discrete semiconductor devices and integrated circuits Parts 5-2: Optoelectronic devices - Characteristics and classification of elements (1997-09)
3.IEC60747-5-3 Discrete semiconductor devices and integrated circuits-Part 5-3: Optoelectronic devices-Measuring methods (1997-08)
IEC60747-5-3 discrete semiconductor devices and integrated circuits
Parts 5-3: Optoelectronic devices - Test methods (1997-08)
4.IEC60747-12-3 Semiconductor devices-part12-3: optoelectronic devices-Blank detail specification for light-emitting diodes-Display application (1998-02)
IEC60747-12-3 discrete semiconductor devices 12-3: Optoelectronic devices - light-emitting diode display space with more standard (1998-02)
5.CIE127-1997 Measurement of LEDs (1997)
CIE127-1997 LED test method (1997)
6.CIE/ISO standards on LED intensity measurements
CIE / ISO LED strength test standards

International Commission on Illumination (CIE) 1997, published CIE127-1997 LED test method, the LED intensity test to determine the concept of average strength, and provides a uniform size of the test structure and the detector, so that accurate test for the LED on the foundation than . Although the CIE 127-1997 test method is not an international standard, but it is easy to implement and accurate test than the right, the world's major enterprises have adopted. But with the rapid development of technology, many new technical features LED CIE127-1997 LED test method is not involved.

Now there are new developments on the market in Japan is to create a complete LED standards fight, with the relevant standards are becoming increasingly clear, LED industry will be more stable.
