    Double fluorescent lamp with glow starting device in the circuit and the ballast series. Glow starting device is a glass bubble. Glass cannon with a U-shaped metal piece of glass tube filled with neon. Connect the power when the neon glow discharge. To generate heat, double metal sheet is heated expansion. Double metal sheet and another contact. Because when the contact resistance is very small. Neon glow discharge. The double metal sheet temperature decreased. With the contact separation. Then the circuit disconnected. Ballast due to inductance effect induced by high voltage. In order to disconnect the radio equipment to produce the electric magnetic interference in the glow starting device is connected in parallel with a capacitor....

    The earliest use of electric light source is incandescent, is our usual said the electric light. It is according to the principle of thermal radiation is made, the tungsten filament to red hot, only a small part of the energy is converted into visible light, electricity consumption can mostly transformed into heat energy, the light emission efficiency is low. So incandescent lamps waste a lot of energy. To emit visible light tungsten to 500 DEG, with increasing temperature, gradually changes from red to orange and white. Incandescent lamp that emits light is light, but the proportion of various colors of light is by luminous material (W) and temperature, the ratio imbalance will lead to partial color color, so in incandescent light the color of objects not true (that is, the color of not high), which is in shopping malls and other public places without the use of incandescent lighting is one of the reasons in order to improve the efficiency of light....

    HID lamp most work in AC state, the use of reactive devices as HID ballast. HID lamps have different types, according to the type of lamp and its application needs, can be configured in different forms of ballast circuit, in order to obtain the best matching ballast and lamp. As a general The commonly used HID lamp for lighting a high-pressure mercury lamp, high-pressure sodium lamp and metal halide lamp. High pressure mercury lamp HID lamp is in the earliest development, stable product performance, supporting mature ballast circuit. High pressure sodium lamp and metal halide lamp is a new energy-efficient light source of modern development, requirements ballast and lamp has good matching, to achieve better comprehensive effect of high pressure sodium lamp and high pressure mercury lamp in the performance of different, high pressure sodium lamp not only mercury, but also filled with sodium, during operation of the lamp, sodium and mercury to form storage of liquid sodium and mercury gas in the discharge pipe of the cold end Part....

    Grille fluorescent light fixture size as below: 2 * 14W, 2 * 21W, 3 * 14W, 3 * 21W:600*600mm 2 * 28W, 3 * 28W:600*1200mm The cost of lighting is the price of electricity and light. The main factor of the cost depends on the power consumption of the light bulb. Beijing Lighting Electric Appliance Association expert told reporters, in fact, each of the eighty percent to eighty-eight yuan of money is spent on electricity consumption. Therefore, for your unit or family to save the cost of lighting, the most scientific way is to buy the most effective use of energy-saving lamps products. Although the price of energy-saving lamps is more expensive than the standard incandescent bulbs, but many examples show that, as long as the election to the high quality energy-saving lamps, the investment is not more than three months to get a return on how to choose the high quality energy-saving lamps....

    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....

    Working principle of electronic ballast: When the lamp current is increased, the working voltage of the lamp tube drop, but supply voltage will not be decreased more of this voltage applied to the lamp tube will make the lamp current rise further, so the cycle, eventually burned out lamp or lamp extinguished, so to make the lamp works normally, should match to town flow components, used to limit and stabilize the lamp current. This limiting device is called a ballast. At present, there are two kinds of ballast for gas discharge lamps. the ballast circuit operating characteristic curve as shown in Figure gas discharge lamp in the AC power supply work, gas or metal vapor discharge characteristics depending on the frequency of the alternating current and the town flow element type. Gas discharge lamp,50Hz/60Hz power supply, the impedance of the lamp during the entire AC power supply cycle has been constantly changing, resulting in a non sinusoidal voltage and current waveforms, resulting in a harmonic component. The working frequency of the gas discharge lamp is about.In 1kHz, the ionization state of the lamp is not changing with the working current of the lamp, thus forming a nearly constant plasma density and lamp impedance in the whole working week....
