China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

The optimization design of the electronic ballast of lighting quality, maintenance costs, building safety, office staff, students learning efficiency and equipment testing and the pollution to the power grid, personal injury and other has a critical influence, should cause height to take seriously today China's lighting has become the overall situation of energy-saving lamps of heaven, and push into the strong momentum of home lighting. Rapid development at the same time also exposed many problems, due to our country to the electronic ballast research and development started late, low starting point, early on the difficulty and lack of understanding of the complexity, special semiconductor device development did not keep up with, product quality can't pass, and the market is not very standardized, a large number of low-cost low-quality goods is left to the market, so that consumers suffered losses, serious damage to the image of the electronic ballast. Until the late 90 's, the production level of the rapid development and improve the momentum, from the circuit design to the electronic components are entered a more mature stage. For high strength gas discharge lamp electronic ballast, although the domestic many units and individuals have spotted the electronic ballast is faced with the tremendous business opportunities, and scrambling to put a lot of manpower and material resources to development, development and production of electronic ballasts, can really entered the mature stage, but very few. So, electronic ballast now exactly in what kind of a status quo? Here, in view of the current situation of the development of the electronic ballast and in the use of choice on personal views with the rapid development of electronic technology, continuously improve the quality of electronic components, the reliability of the electronic ballast is the basic guarantee. Therefore, the low-pressure gas put lamp lighting circuit has a large number of electronic ballast replaced. For the electronic ballast for a large number of applications in high pressure gas discharge lamp, must solve the high-pressure gas discharge lamp with the problem of the reliability of electronic ballast and the price of high pressure gas discharge lamp is a fluorescent lamp has more complex physical processes, we must deeply understand the characteristics of high pressure gas discharge lamp to effectively design and reliability and is suitable for the working characteristics of the ballast circuit. Such as "acoustic resonance of high-pressure gas discharge lamp is lighting in the process of discharge electrode unstable phenomenon, serious cause the lights went out, even can not work normally, in the design, I think the following considerations indispensable.

Keeping the lights on the instantaneous output power constant, such as the use of Party wave current drive can get lamp instantaneous output constant power output characteristics, and ensure that no phenomenon of acoustic resonance fluorescent lamp life is determined to launch capability of cathode fluorescent light fixture. Lamp current crest factor is affecting cathode emission capability and emission current stability are important indicators and standards provided by the state control in less than or equal to 1.7 and lamp current crest factor is high, cathode lamp by injury, lamp blackening time accelerate, life is bound to decline, the lamp current crest factor is too large, will bring additional flashing riding on China's implementation of green lighting project, in the spring breeze, the popularization and application of the electronic ballast paved the way, domestic electronic ballast in the near future will be able to occupy a place in the competition in the international market. The high-end electronic ballast for domestic demand increase, due to high prices of imported products to the domestic enterprises, the development of the domestic market, some production of high quality products to export the vitality brought with the green lighting project in China is deepening, people of green lighting products demand increases increasingly, especially the high performance electronic ballast with its superior performance, moderate price, high power factor, high efficiency, low lamp current wave crest ratio, good electromagnetic compatibility: does not pollute the power grid, will not interfere with other medical equipment, computer systems and other features and advantages of electrical equipment work will gradually replace the magnetic ballast.
