In China's ballast market, traditional magnetic ballasts occupy the majority of the market. The traditional inductive ballast produced in China is still an old product since the 1930s. It consists of silicon steel sheet wrapped around enamelled copper wire. Although it has the advantages of simple structure, high safety factor, durability and low price, Due to its high noise, high stroboscopic, high power loss (40W for the lamp's own loss of 9W) and low power factor, it is increasingly unable to adapt to the trend of "energy saving, environmental protection". In recent years, with the changes in the demand environment of the entire lighting market in China, the demand for ballasts in the lighting market has also undergone great changes. Energy-saving magnetic ballasts and electronic ballasts have gradually replaced traditional magnetic ballasts. Among them, the energy-saving magnetic ballast adapts to the current two trends of “energy saving†and “environmental protection†in the Chinese market due to its outstanding energy saving and practicability, showing a strong development momentum and huge market potential.
First, the development of energy-saving magnetic ballasts
For more than 20 years, with the development of power electronics and environmentally-friendly energy-saving lighting technology, the technology and products of electronic ballasts have grown rapidly. Traditional magnetic ballasts have ushered in new challenges in cross-industry power, electronics, communications, Under the influence and enlightenment of the instrument and power inductor industry, the birth of a new generation of energy-saving magnetic ballasts has been promoted.
In the late 1980s, the United States applied ring-type magnetic ballasts to compact energy-saving fluorescent lamps. In 1988, Midwest Toriod began mass production. In the early 1990s, China-US joint venture Qingdao Pacific Lighting Co., Ltd. used ring-shaped iron core to produce plug-in energy-saving fluorescent lamp ballasts, which has been more than 10 years old.
Practice has proved that the magnetic ballasts produced by the ring core are no different, they are power frequency inductors, and the structure is more compact, with a small size, light weight, low power consumption, low noise, high frequency electromagnetic radiation, anti-grid Interference and other advantages. Especially in the past 10 years, energy-saving magnetic ballasts such as ring type and compensation type have lower and lower power consumption and better performance. Due to the improvement of the quality of the silicon steel sheet, the enameled wire, the insulating material, the production process technology, and the tooling equipment, the energy efficiency and quality of the power frequency magnetic ballast are improved. Especially the E-type, ring-type and compensation type are from traditional type to energy-saving type. The self-loss power consumption is greatly reduced, with low temperature rise, short-time strong electric shock, small inrush current, strong overload capability, good peak-to-peak ratio, safe and reliable. Good stability and high light efficiency.
Energy-saving magnetic ballasts are about 40% more energy efficient than conventional magnetic ballasts and are close to the level of electronic ballasts. From the current market monitoring results, as the energy-saving magnetic ballasts are more in line with China's current market economy and consumption levels, the 2001 energy-saving magnetic ballasts have been recognized by the market and began to be accepted by the market, due to the energy saving of many professionals in the industry. The good evaluation of energy-saving ballasts in the energy-saving and comprehensive, the various market factors of the industry began to be mobilized, and the products began to enter the growth period. Market monitoring data shows that energy-saving magnetic ballasts account for 6.5% of total ballast output, annual share growth of 2.1%, and advance to the market with an annual growth rate of 64.2%. Energy-saving magnetic ballasts in China The market environment is getting better and better:
(1) The promotion work has received strong support from the government and relevant institutions.
Since the implementation of "green lighting" in China, the government has attached great importance to the promotion of energy-saving electrical products. Energy-saving magnetic ballasts have been listed as “China Green Lighting Promotion Products†due to their good energy-saving effect, high reliability and economy. In November 1999, the State Bureau of Quality and Technical Supervision promulgated the National Standard for Energy Efficiency Limitation and Energy Conservation Evaluation of Tubular Fluorescent Lamp Ballasts, which was officially implemented on June 1, 2000. This standard specifies the minimum energy consumption value that must be achieved by the ballast. If the ballast does not reach this minimum limit, production and sales are not allowed. In addition, the certification standards for energy-saving ballasts are specified. The inductive ballast of this certification standard can be named as an energy-saving magnetic ballast.
Under the guidance and support of the Green Lighting Office of the State Economic and Trade Commission, the International Copper Association (China) and the China Light and Lighting Committee of the China Illumination Society jointly established the “Coordination Group for Energy-Saving Inductive Ballast Promotion Work†in December 1999. The National Energy Foundation and Management Standardization Technical Committee and the China Energy Conservation Product Certification Center have successively joined the coordination group. The organization's work has played an important role in promoting the market application of energy-efficient magnetic ballasts.
(II) The scale of production is growing day by day.
Inductive ballasts are mainly used for tubular fluorescent lamps and high-intensity discharge lamps. In 1999, the output of fluorescent lamps in China was about 500 million, and the output of electronic ballasts matched with it was about 40 million, which was basically the same as that in 1997. The output of magnetic ballasts matched with 110 million was increased compared with 1997. Nearly 30 million.
The manufacturers of magnetic ballasts are mainly concentrated in China's Guangdong, Zhejiang, Shanghai, Jiangsu, Beijing, Tianjin, Henan, Fujian, Shandong and other places. Its China Camp Guangzhou Jiufo Electrical Appliance Factory is currently the largest output and largest size of magnetic ballasts. The production plant has an annual output of nearly 20 million magnetic ballasts.
At present, many enterprises have gradually seen the development direction of magnetic ballasts, and have begun to develop, develop and produce energy-saving magnetic ballast products, such as Guangzhou Jiufo Electric Appliance Factory, Qingdao Pacific Electric Co., Ltd., Zhejiang Jiangshan Sanyou Electronics Co., Ltd., etc. .
(3) The supply and demand market is gradually maturing
Although there are not many manufacturers of energy-saving magnetic ballasts in China at present, the market situation is quite optimistic from the demand of energy-saving magnetic ballasts by users at home and abroad. The energy-saving magnetic ballasts of Guangdong's “Foshan Inter-Heavenâ€, “Dongguan Shijun†and “Zhanjiang General Electric†factories have a monthly export volume of over 1 million. The export of circular ballasts in Zhejiang “Yuyao Yangming†and “Dongguan Huanya†is also in short supply.
In the past 10 years, the design and process of energy-saving magnetic ballasts have matured from immature to mature. The professionals of lighting appliances and the users of lighting appliances have realized the knowledge of energy-saving lighting products. Ballasts are energy-efficient lighting electrical products and gradually realize that many energy-saving lighting appliances, including energy-saving magnetic ballasts, have unique advantages in energy conservation and comprehensive assessment.
Inductive ballasts have great potential for energy saving. If the traditional magnetic ballasts produced each year are completely replaced by energy-saving magnetic ballasts, it can save 900 million kWh of electricity per year, which is equivalent to saving 1.116 billion yuan in investment in new power plants. To reduce the emission of 1 million tons of carbon dioxide, the economic benefits and environmental benefits are very obvious.
These indicate that China's huge lighting market urgently needs ballast products that are both energy-saving and in line with China's national conditions. Energy-saving magnetic ballasts will have low price, low harmonics, no high-frequency interference, high reliability and energy saving effect. Obviously, it has become the leading product in the future Chinese ballast market.
