The LEDs that have been vocalized for a long time, that is, the standardization work of LEDs, have made rapid progress this year. Relevant national standards have been released, and some standards have been officially implemented since April. At the beginning of this year, the Ministry of Industry and Information Technology approved the issuance of nine industry standards; the National Standardization Administration issued six LED-related standards, plus two mandatory national standards, a total of eight.
The introduction of a series of new standards in China will help promote the development of China's LED industry and technological innovation, while promoting the more standardized and healthy development of the LED lighting industry.
The standard is not the threshold. Currently, in addition to the "Safety Requirements for LED Modules for General Lighting", the control device for lamps, Part 14: Special requirements for DC or AC electronic control devices for LED modules will be officially implemented at the end of this year. It was officially implemented from the beginning of the year. Whether these standards can really play their role, the reporter has learned about the company.
The standard will become the threshold for the cottage enterprises, a salesman of a Dongguan LED manufacturer told reporters.
A quarter of the country's LED manufacturers are in Guangdong, including many small family-owned workshops. These small manufacturers rely on price advantage, short production cycle, and some customers in the low-end market. The products produced by these small enterprises are basically difficult to meet the requirements, and these enterprises may be rejected by the standards.
Conversely, for large companies, standards are not thresholds, but provide more advanced technology benchmarks. Relevant personnel of three well-known LED companies such as Osram (China) Lighting Co., Ltd., Guangdong Xuelaite Optoelectronics Technology Co., Ltd. and Shenzhen Lehman Optoelectronics Technology Co., Ltd. all said that the standard is not a problem.
Mr. Zhang from Shenzhen Lehman Optoelectronics Technology Co., Ltd. told reporters that this series of standards provides effective data for the production and testing of products. Li Zili, a senior engineer at the Guangdong Provincial Institute of Product Quality Supervision and Inspection, conducted an analysis. He said that "Safety Requirements for LED Modules for General Lighting" provides detailed data on whether the heat dissipation of the product is qualified. The heat resistance is checked by the ball pressure test: the test temperature is 5 ° C, but the minimum is 75 ° C, and the indentation diameter must not exceed 2 mm. The fire protection was tested by a 650 ° C glow wire test: the glow wire was 650 ° C and the glow wire was applied to the sample for 30 s.
Standards will keep pace with the times After the introduction of this series of standards, some companies have questioned the advanced nature of the standards. Mr. Zhang of Lehman Optoelectronics Co., Ltd. said that at present, the performance requirements of LED application products are constantly changing and improving, and the products are not yet mature, so it is difficult to formulate appropriate application product standards. Perhaps the standard has just been formulated, and the technology of the product has greatly exceeded the current standard level.
He believes that the standard of LED will be gradual. The establishment of standards requires a process. Many products have not yet been finalized, and the technology is also developing with each passing day. Therefore, standards can be set in a step-by-step and planned manner according to the development progress of the LED industry.
Based on the current development of the industry, relevant persons from the Ministry of Industry and Information Technology said that the release of these nine electronic industry standards is only the first step in the standardization of lighting technology. The work of perfecting and perfecting this standard system is still a heavy task. Daoyuan. The relevant standards working group has already started, and is developing new electronic industry standards, including test methods and technical specifications for LED application epitaxial wafers, technical specifications for low-power LED chips, naming rules for LED devices, and reliability test methods for LED components. And the series of standards for the feasibility of solid-state lighting, these are to be completed this year.
In addition, the standard working group will also develop test methods for LED module components, develop series of standards for power ICs and control ICs, and develop detailed specifications for LED device products for different applications.
The development of standards is part of the standardization work. This standard also needs to be modified and improved during the implementation process. Therefore, it is hoped that the company will promptly report the problem to the standard working group in the process of using these nine standards, so that the standard working group can better Improve the standard level and further serve the industry.
In addition to the dispute over the right to speak, the standard has another important significance - the fight for discourse power. The urgent need for the introduction of national standards will change the current situation of multiple standards and increase the competitiveness of China's industry standards in the international arena.
In 2010, China's LED sales value will exceed 150 billion yuan, this figure is twice as much as in 2008, and continues to grow at a rate of 30 per year. Obviously, the LED industry stands out and has become an emerging industry for many businesses around the world. With the development of the industry, the world's advanced countries have put the development of standards and testing technology into an extremely important position, in order to occupy the commanding heights of industry standard evaluation technology.
At present, the standards of various regions in China are also being drafted. Previously, the first local standard for LED street lamps in Jiangxi was approved. The local standard for road lighting LED lights in Shaanxi Province was also released. Shenzhen also released the first LED road lighting product standard. Today, there are local standards, and the "Guangdong Province LED Street Light Local Standards" was officially implemented.
Of course, these standards will change the current state of the disorderly LED market to some extent.
However, these standards are often mixed with their own interests. The inconsistency of standards indulges local protection and creates a grey area, which will also breed a lot of unfair competition. A professional said that China needs a unified standard to strongly enhance the international voice of LED domestic manufacturers.
Recently, international monopoly manufacturers began to seize the right to formulate LED standards. South Korea and Japan are constantly introducing their own LED standards. Recently, the US Department of Energy also released a confirmed version of the LED luminaire standard.
It can be seen that the battle for the right to speak of LEDs has begun.
