Today, with the rapid development of the economy, "green consumption" has attracted more and more people's attention. The "green concept" has become a manifestation of the comprehensive quality and civilization of a country and a nation.
China has a large population and relatively insufficient resources. How to deal with the relationship between population, resources, environment and development, and improve resource utilization is a long-term national policy of the Chinese government. A key experimental project to save energy, protect the environment, and improve lighting quality during the period of the Ninth Five-Year Plan - China Green Lighting Project, "China Green Lighting Promotion" jointly organized by the State Economic and Trade Commission, the United Nations Development Program, and the Global Cooperation Fund The project was officially launched, and the policy and financial support for green lighting was increased.
3. Development status, trends and characteristics of electrodeless lamps
3.1, development status
More than 90 years ago, Americans Thompson, Tessler and others invented high-frequency induction lamps. However, due to the limitations of the technological level at that time, it was not until the 1990s that the rapid development of new technologies, the increase in the power density of electronic components and the corresponding reduction in size made it possible for high-frequency electrodeless lamps to enter the commodity field. Since the introduction of the electrodeless lamp, lighting companies all over the world have carried out a lot of research and practice on the electrodeless lamp. Philips abroad, GM in the United States, Osram in Germany, and Matsushita in Japan have been working on the research and development of high-frequency electrodeless lamps for many years and have achieved many results. In 1991, Philips announced the successful development of 55W induction lamps. In the following five years, 85W and 165W high-frequency induction lamps were successively developed.
High-frequency electrodeless gas discharge lamps are new light source products for the development of international lighting fixtures. Because it involves a number of special performance materials science, the key technical problems of the manufacture of new high-performance components, circuit design and electromagnetic interference shielding, the technology is relatively new, the process requirements are high, the production is difficult, and there are few manufacturers who master the core technology. The product price is high, and it is difficult for the product to achieve high performance and low cost uniformity, and the market share is small.
Due to the world energy crisis in recent years, the call for energy conservation, low consumption and low carbon development is becoming more and more urgent. Following the ban on the use of incandescent lamps in countries such as Australia, Canada, the United States, or their provinces, EU countries have also reached an agreement. After 2009, the production and use of incandescent lamps will be gradually banned. Nowadays, incandescent lamps that have been popular in the world for more than 100 years have already bid farewell to these major Western countries. Energy-saving lamps will become the mainstream of lighting sources, while high-frequency electrodeless lamps and high-power energy-saving lamps will lead the energy-saving trend.
At present, domestic high-frequency electrodeless gas discharge lamp technology is mainly to track foreign technology. Domestically produced enterprises are few and most enterprises have small production scale, and the market price of products is high. The cultivation and development of the domestic market are greatly restricted. The existing large-scale production lines of high-frequency electrodeless gas discharge lamps are almost all introduced, 70% of which are used for export, and the industry is in the stage of starting and promoting application.
