Esp works: when the two electrodes of the starter are attached to the power exchange of 220 v50hz on the shut-off circuit, the current flow passes through the convulsor, the light light light is heated to the light (the light light is activated at the beginning of the lamp, the gas arc of the ejection in the light greater than 190 v is activated by the application of a communication voltage voltage greater than 190 v, the exact voltage of which depends on the type of light, the two electrodes lean together to form a light for the light), when the two electrodes of the starter are held together, when there is no a light discharge, the two metal blades cool, the dichotomy is separated, and the electrical current is sensory, and when there is an abrupt break in the light, the pulse of 600 v-1500v at the end of the light at approximately 1 ms, the exact voltage depends on the type of light, and the light is brought down immediately, at which time the current is restricted on the one hand of the electric current, and the power flow is kept between 55° and the working light is energy-efficient electrons have a more reliable starting point.

The electrons (inductanceballast) is an iron core wire, which, when the current changes in the wire, causes magnetic changes in the online loop, thus creating a sensory electric motion in the opposite direction of the current and thus hindering it. Used in sunlight. When the communication power of 220 v50hz is applied in the shut-off circuit, currents heat up the light through the ballasts, the lamplights, the flashlights (the flashlights were opened at the beginning with a communication voltage greater than 180 v, resulting in the discharge of the gas light in the bursting of the light, the deformation of the two metal fragments in the bubble, which are attached to the two electrodes and form a road for heating the light). When the two electrodes of the starter leaned together, because there was no arc-light discharge, double-metal tablet cooled, the two electrodes were disconnected, and when the electrons were sensory, when the currents of the two electrodes suddenly disappeared, they generated a high-pulse voltage voltage, which was superimposed with the electric voltage and added to both ends of the lamp tube, causing the inert gas ionizing in the lamp tube to cause the arc discharge.

Electronic ballast applications: electronic ballasts have a clear advantage in improving energy efficiency and quality of lighting systems, are products for new internationally recommended applications and are trends for future development. Selective recommendations: (1) in places of continuous stress and high visual conditions, priority should be given to places requiring special quietness (patients, clinics, etc.) and places for young people (classrooms, reading rooms, etc.). (2) in places where light is required, three-base fluorescent lamps may be used to replace incandescent lamps or halogen lamps with fluorescent digital ballasts, which can significantly increase energy efficiency. (3) high-quality, low-intensity products should be selected, not simply for low-cost products, but for the technical requirements of use, considering operational maintenance effects and making comprehensive comparisons. (4) when less than 25w fluorescent lamps are selected, the harmonization limit specified in the gb17625. 1-2003 standard is very wide and, if applied in large quantities in a building, will result in multiple adverse consequences. Effective measures should be taken to limit them. (5) the product selected should not only look at its total input power but also at its output light flux. The flow factor (m) for the use of ballasts shall not be lower than 0. 95. The eu has established a level of energy efficiency for tradables and correspondingly a μfluorinated coefficient of 0. 96。
Advantages of electronic ballasts: energy saving: electronic ballasts for fluorescent lamps, with an additional 20-60 khz frequency supply of lamps, increase the lighting effect of lamps by about 10 per cent over the frequency of work (4-foot length lamps) and reduce the total input power of lamps by about 20 per cent, with better energy efficiency. Fluctuation has been eliminated and light has become more stable: it has contributed to improved visual resolution and effectiveness; and it has reduced visual fatigue for continuous operations and helped to protect vision. The starting point is more reliable: the second starting point for the preheat lamps was successful and multiple starting points were avoided. High power factor: fluorescent lamps above 25 w that meet national standards, with a power factor above 0. 95. It should be noted, however, that the harmonization limit set by national standards for lamps below 25 w is high, reducing their power factor to 0. 7 ~ 0. 8. Electronic ballasts have a clear advantage in improving the efficiency and quality of lighting systems。
What are the specific effects of fluorescent light ballasts? Article 1 is energy saving: for this device, a frequency of 20 to 60 hz is usually used to power the lamps. This will result in an increase of about 10 per cent in the relative light power of the lamps relative to the frequency of work, a lower consumption of its own, and a 20 per cent reduction in the power of the lamps, thus saving energy. Article 2 is the complete elimination of flashes and the promotion of a stable light. This has significant benefits for the relative improvement of visual resolution; at the same time, it can help people to overcome their eyes fatigue and thus protect them while working long hours. Article 3 is a reliable starting point. This type of device allows the lamps to preheat and light at a time. Article 4 is the function of a stable input power and a stable output of light flux. This type of device has a good pressure function that keeps the light source more constant, and that can be relatively stable and energy-efficient. The characteristic curve of the compressor shall intersect with two light voltage lines. How's nanking's current
The number of electro-voltage control lines for electro-voltagers can be divided into two- and four-line systems. Hangzhou ring trailer plant

In the face of the enormous market space created by the expansion of led lighting to replace traditional lighting and special lighting applications, the lighting industry has been transformed to expand the led business volume. With the rapid growth of urbanization and the escalation of consumption, the standard of living of the population is rising, the demand for urban quality is rising, and the urban lighting industry is closely linked to urban economic, cultural and natural factors, which play a crucial role in shaping the city's image as a whole. In the future, as lighting energy-saving technologies continue to develop, traditional lighting limited (natural) markets are being converted from incandescent lamps to leds, and new generations of information technologies, such as connectivity, the next generation of internet, cloud computing and so forth, have become inevitable trends in smart cities.
