LED lamps suffered technical barriers and Guangdong enterprises faced 4 billion losses

Technical barriers to trade have become the biggest obstacle to the export of LED lighting products in China. The WTO/TBT Center of the Guangdong Provincial Bureau of Quality Supervision announced yesterday that the United States and the European Union have proposed higher and stricter requirements for directional lights and LED lighting products in the country of entry covering energy saving and environmental protection, eco-design, energy efficiency labeling, and testing and inspection.

Qu Shirong, director of the Guangdong Semiconductor Lighting Industry Co-Innovation Center, called on companies to improve the international quality of their products and adopt the global certification standards system to first model and deal with global technological trade barriers.

Predicament Guangdong LED companies have a significant cost increase. Europe and the United States as the world's most important LED application base, using high-demand technology and safety standards as technical barriers, are rushing to Guangdong LED export companies.

The WTO/TBT Center of the Guangdong Provincial Bureau of Quality Supervision announced yesterday that the TBT notifications on LED lamps in the European Union, the United States, Chile, and Uganda have set a higher threshold for directional lights and LED lighting products in the country of entry. For the directional lamps and LED luminaire products of the country of entry, higher and more stringent requirements covering energy saving and environmental protection, ecological design, energy efficiency labeling, test and inspection, performance, safety, size, weight, and shape are proposed. For example, the European Union put forward high energy efficiency requirements for directional lights and LED lights. The notified regulation requires that only directional LED lamps and directional fluorescent lamps with an energy efficiency index of more than 0.2 can enter the EU market, which is 2.5 times higher than the previous energy efficiency requirement, which is 2.2 times the current national standard requirement.

It has been estimated that in accordance with the aforementioned energy efficiency requirements, the production cost of LED lamps will directly increase by more than 20%, and Guangdong LED companies will incur an additional cost of over RMB 2 billion.

In addition to energy efficiency requirements, the requirements for conformity assessment and market supervision inspection procedures for directional lamps and LED luminaires in the country of entry are increasingly demanding, which will bring huge test cost costs to companies.

Another example, the United States reported this test program such as LED, according to preliminary estimates, an enterprise if required with the appropriate testing laboratories and testing equipment, you need to spend about 350,000, but also in the laboratory every year, equipment maintenance and Laboratory personnel pay about 100,000 in cost. There are more than 3,000 LED companies in our province, and most of the company's products are exported to the United States. The LED test procedure announced by the United States only brought additional costs of more than 2 billion yuan to LED export enterprises in our province.

It is recommended to model the system through the global certification standard system. Guangdong Province is a major province of LED lamps and a major exporter. In 2011, the LED output value of Guangdong Province reached 150 billion yuan, accounting for about 70% of the country, 50% of the world, and it is growing at a rate that doubles every year.

The United States and the European Union are the major importers of LED products in our province. In 2011, the export sales of LED lamps in Guangdong exceeded RMB 34 billion, which is more than 20% higher than that in 2010, accounting for almost one-fourth of the total output value of LED lamps in Guangdong. Among them, exports to the United States and the European Union amounted to approximately 22 billion yuan, accounting for about two-thirds of the export value of LED lamps in Guangdong, and accounting for 15% of the total output value of LED lamps in Guangdong.

How to crack the above technical trade barriers? Representatives and experts from the UN Home Lamp Quality Inspection Center (Guangdong) and Guangdong's 15 leading LED lighting companies recently held a seminar in Zhongshan. They believe that the coordination mechanism under the WTO/TBT Agreement should be used first to encourage European and American countries to adopt our provincial government. The comments made.

To this end, they jointly report directly to countries in Europe and the United States, requesting the United States to refer to the current practices of the IEC (International Electrotechnical Commission) and other WTO members, simplifying the requirements for the test environment and test methods, reducing the number of test samples and the number of tests, and shortening the number of tests. The length of time to reduce the burden of product testing for LED lighting manufacturing companies and avoid unnecessary trade barriers to foreign LED lighting products entering the US market. And requested the EU to appropriately reduce the minimum energy efficiency requirements for directional lamps and LED lamps, and postpone implementation of this requirement by more than one year, so that companies can better adapt to the changes brought about by the regulations.

At the same time, they also suggested increasing the policy and financial support for the development of technical barriers to foreign trade. In particular, increase investment in R&D of LED core technologies.

Zhen Shirong urged enterprises to improve the international quality of their products by adopting a global certification standard system and strengthening the standardization work of LED products. Converting international standards and foreign advanced standards into local standards of our province, and establishing a LED product standard system that is in line with international standards. The LED products in our province meet the technical requirements of the international market and respond to global technological trade barriers.


The Co-Al Co-doped Barium Titanate Lead-free Piezoelectric Ceramics was successfully developed by Yuhai company through repeated experiments. By Researching the influence of Co-Al Co-doping on the structure and properties of Barium Titanate-based piezoelectric ceramics, the formulation and preparation technology of Barium Titanate-based piezoelectric ceramics were optimized. Yuhai`s BaTiO3 was prepared by conventional solid-phase sintering method, with the piezoelectric constant d33 (>170pC/N), dielectric loss tgδ≤0.5% and mechanical coupling coefficient  Kp≥0.34.

Barium titanate lead-free piezoelectric ceramics are important basic materials for the development of modern science and technology, which was widely used in the manufacture of ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic frequency discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optic devices, ignition and detonation devices, and piezoelectric gyroscope and so on.

Application:  military, ocean, fishery, scientific research, mine detection, daily life and other fields.
