Ballast: Electronic Ballasts tend to be integrated
The global energy crisis of 1973 led many companies to focus on the research of new energy-saving electric light sources and electronic ballasts for fluorescent lamps. In the late 1970s, companies such as Philips in the Netherlands pioneered the first generation of electronic ballasts. Subsequently, Germany's Siemens, the United Kingdom Thorn, the United States singular, Germany Osram and other companies have introduced integrated circuit electronic ballasts. In 1989, Finland's Hell Valley Company successfully launched the dimmable monolithic integrated circuit electronic ballast. It was not until the early 1990s that China really began to develop electronic ballasts. Until 1998, the production level of domestic electronic ballasts has been rapidly developed and improved, and the circuit design to the electronic components have entered a more mature stage.
At present, there are more than 200 electronic ballast production plants in China. One-fifth of the products sold on the market are ordinary electronic ballasts, high-power electronic ballasts account for 3/5, and high-performance electronic ballasts account for one. /5. However, the products meet the international GB/T17263 manufacturers less than 20%. The built-in electronic ballast is mainly used in ultra-thin brackets. The specifications are single lamps 18W, 36W, mostly common. The annual output of the country is about 5 million. The independent electronic ballast is suitable for T12, T10 and T8 tubes. The mainstream products are single lamp, double lamp 18W, 36W, single lamp 58W. The three lamps 18W and 36W that are output in parallel are very popular varieties. Due to their high power and production difficulties, they rarely appear on the market.
