Semiconductor lighting has gradually gained market recognition due to its long life, energy saving, safety, environmental protection and other advantages. Especially in the case of LED lamps that replace traditional light sources, it is convenient to replace traditional light sources with LEDs without replacing lamps. The light source has become the first major form of LED lighting products that occupy the market. For example, LED bulbs that replace ordinary incandescent lamps appear on the domestic and international markets, instead of reflective incandescent LED-R lamps and LED-PAR lamps, instead of MR16. Halogen LED-MR16, and the market potential is the biggest in the future, but there is some controversy is a double-ended straight tube type LED lamp that replaces ordinary double-ended fluorescent lamps. This type of LED lamp is basically designed with reference to the fluorescent lamps of T8 and T10. The built-in drive control circuit (also not designed to be externally installed) has G13 bases at both ends of the lamp, and the external dimensions are the same as traditional fluorescent lamps such as T8\T10. It can be easily used in the original fluorescent lamp panel, and the goal is to replace the straight tube type fluorescent lamp used in the office.
GfK Japan has released a survey data recently. In June of this year, the sales volume of LED bulbs in the Japanese market was 43.5%, surpassing 38.2% of traditional bulbs for the first time. The field of ceiling lighting recessed lights is also the leader in LED products, accounting for 42.7% of the total sales. Compared with LED light bulbs, the price of straight tube type LED lamps is still high, but after the 311 Japan earthquake, the energy saving boom spread rapidly across Japan, and all major companies are required to achieve the goal of 15% power saving. The market size will be even larger, and commercial lighting is the best entry point. In the markets of Europe, America and China, with the improvement of the awareness of energy conservation and environmental protection in the whole society, more and more office buildings, shopping malls, underground parking lots and other public places carry out lighting energy-saving renovation, and the demand for straight-tube type LED lamps will also increase. The bigger it is.
However, "the lack of standards for the safety and performance of straight tube LED lamps is hindering the development of China's straight tube LED lamp industry." Ke Jianfeng, chairman of Zhejiang Shangguang Lighting Co., Ltd. told reporters. Since there is no uniform standard for straight tube type LED lamps, and some manufacturers do not understand the safety knowledge of lighting electrical products, some lighting electrical products are not qualified in the safety requirements such as heat resistance, fireproof and flameproof, insulation resistance, electrical strength, etc. For example, there is confusion in performance indicators such as light efficiency, color temperature, and color development. What is worrying is that the Japanese and South Korean governments are stepping up efforts to promote the development of straight-tube LED lamps, not only rapidly introducing relevant standards, but also supporting enterprise transformation. Under this circumstance, if Chinese lighting companies cannot quickly develop strength in technology development, personnel training and brand building, the high point of the industry will be occupied by enterprises in Japan and South Korea, and Chinese LED lighting enterprises will become foreign enterprises. Processing factory.
In view of the situation in the industry, although the development of straight tube type LED lamps is still controversial in the industry, in order to provide some safe and standardized development technical support for the rapidly developing market, National Semiconductor Lighting Engineering R&D and Industry Alliance combines with China. For the specific conditions and test verification data of the variety and quality level of straight tube LED lamps for general lighting, the development of "Safety Requirements for Straight Tube LED Lamps for General Lighting" and "Performance Requirements" were initiated. The researcher of China Optoelectronic Technology Development Center and the chairman of the Zhejiang Lighting Society, Chen Zheqi, have drafted the first draft on the basis of a lot of research and feedback from the industry. On August 23, at Hangzhou Optoelectronics Co., Ltd. With strong support, the Alliance held a seminar on the theme of “Performance and Safety Technical Specifications for Straight Tube LED Lightsâ€, with a view to promoting China's work on the specification of straight tubular LED lamps, standardizing product production and ensuring semiconductor lighting. Healthy and orderly development.
In the process of technical specification discussion, deepening the research components in the standard formulation has become one of the focuses of the participating experts. Liu Muqing, a professor at the Institute of Electric Light Sources at Fudan University in Shanghai, pointed out that LEDs are developing rapidly. In the process of compiling technical specifications and standards, not only editing and writing work, but also more attention should be paid to the study of standards. Do a lot of work, some data can draw on relevant standards at home and abroad, but there should be research when the data is not in the source, to figure out why the data is set to do so.
It is also the focus of experts to find out the purpose of technical specifications and to grasp the scientificity, accuracy and appropriateness of parameter setting. Zhao Jianping, deputy dean of the Institute of Building Environment and Energy Conservation at the China Academy of Building Research, pointed out that the development of standards and technical specifications must first be clear about what the purpose is. If it is to replace the T5, T8 fluorescent lamps, then you should compare the LED lamps made with technical conditions better than T5 and T8. In terms of performance, all technical parameters, including color, brightness, efficacy, and light decay, must be close to and beyond T5 and T8. Only in this way can there be an alternative value. When formulating specifications, you should grasp the performance requirements of the technical parameters in the specification. Secondly, in the formulation of technical specifications, it is necessary to clarify the use of the products, in the office, or in underground parking lots and warehouses. The performance parameters of the lamp used in different places should not be the same. The color rendering index required by the office is at least 80, but in the underground garage and factory, 60 is enough. The scope of the applicable product should be clearly defined when developing the specification.
Promoting enterprise product innovation through standard formulation is another issue that experts are concerned about. Dr. Chen Chi from the Chinese Academy of Metrology pointed out that the development of the LED industry requires standard support. In this process, it is necessary to consider clearly whether the focus of enterprise development products is substitution or innovation. The national “Twelfth Five-Year Plan†definitely regards semiconductor lighting as a very important content. In the development, in recent years, the pace of development of Chinese enterprises in the field of LED lighting applications is also very fast, although there is a gap in the high-end, but the problem is that most companies are aiming to be replaced, the standard specification is also pointing Alternative products are for the purpose. It is hoped that future standards and norms will be formulated and can make a difference in innovation and guide the development direction of the LED industry.
In addition, Yu Shukui, deputy chief engineer of the General Architectural Design and Research Institute, Zhang Haicong, former chairman of the Shanghai Lighting Society, Li Zili, director of the lighting department of the Guangdong Provincial Product Quality Supervision and Inspection Center, coordinated by the Office of the Top Ten Industry Leading Groups in Hangzhou Li Xiaohui, deputy director Pan Xuedong, Wu Yongqiang, director of the Electric Light Source and Lighting Professional Committee of Zhejiang Lighting Society, and Wang Shen, an engineer of China Saibao Laboratory Quality and Safety Testing Center, also expressed their opinions, and from Hangke Optoelectronics, Philips Representatives from more than ten companies including Hangzhou Yuanfang, Shangguang Lighting, Shenghui Lighting, NVC Optoelectronics, Inspur Huaguang, Xiamen Topstar, Zhejiang Sunshine, Aoliang, and Shifu have made in-depth technical specifications. discuss.
