1 Introduction
As an emerging high-tech and industry, semiconductor lighting has remarkable features such as rapid development, rapid change, fast update and high technical content. In recent years, the application of lighting LED has become more and more extensive. The product standardization system is an important basic technology platform for industrial development and an important condition for guiding product production research. For the standardization system of semiconductor lighting, it is still in the process of establishment and research abroad. Although China's relevant standards and evaluation systems for semiconductor lighting are weak, through scientific decision-making, high-efficiency organization and active technical research, continuous improvement and improvement of standardization work will effectively promote the technological progress of lighting semiconductor products and promote The production and quality of lighting LED products are improved, the market is regulated, and the industry is healthy.
2. International lighting LED standards
The International Electrotechnical Commission (IEC) assigns lighting semiconductor product standards to the IEC/TC34 (lights and related equipment) standardization technical committee counterpart management and formulation. The standards for test methods are developed by the International Commission on Illumination (CIE).
3. The current existing LED standards of the IEC include:
(1) IEC62031. LEDModulesForGeneral Lighting-safetyRequirements is the safety requirement for LED components for general lighting.
(2) IEC 60838-2-2. Miscellaneous Lam-pholders Part 2-2: Particular Requirements Connectors for LEDModules - Part 2-2: Particular requirements for connectors for light-emitting diodes.
(3) IEC61347-2-13. LampControl-gear-Part2-13: ParticularRequirementsford. c. Ora. c. SuppliedElectronicControlgearforLEDModules Lamp Controls - Part 2-13: Particular requirements for AC/DC electronic control units for LED components.
(4) IEC 62384: Performance of Control-gearForLEDModulesD. C. orA. C. SuppliedElectronicCont-rolgearsforLEDModules PerformanceRequirements LED/DC electronic control unit performance requirements for LED components.
4. CIE related LED standard publications include:
(1) CIE127-1997: MeasurementofLEDs
(2) Light-emitting diode (LED) measuring method
Both the International Electrotechnical Commission (IEC) and the International Commission on Illumination (CIE) are very concerned about the development of LEDs and the standardization of LED-related devices. In the 1990s, CIE published a technical report on LED detection methods. Due to the rapid development of LED products in recent years, many of the technical features of LED devices discovered today have not been considered in the past.
Therefore, CIE is currently revising the standards for test methods. In the past two years, the IEC has also increased the research on LED standards. Standard drafts have been proposed for LED modules, LED connectors and LED control parts. Some drafts have been converted into official standards. Japan introduced the white LED standard as early as 1999, and proposed the IECTC34 technical committee to incorporate the LED standard into the lighting device standard at the IEC annual meeting in Kyoto, Japan. In recent years, the standard has been carried out. Revised. According to the characteristics of lighting LEDs, the United States is also studying the technical standards and test methods for lighting LEDs.
