Research on the reliability of electronic ballasts
With the rapid development of electronic technology and the increasing quality of electrons, which provides basic assurance of the reliability of electronic ballasts, many of the current lighting circuits for solar and energy-efficient lamps have been replaced by electronic ballasts. The reliability and performance ratio of hd-enabled electro-convulsors must be addressed for their large-scale application on hid lamps. The hid lamps are more complex physical processes than solar lamps, energy-efficient lamps, etc., and a deep understanding of the characteristics of the hid lamps is required to effectively design reliable circuits. For example, the “sonic resonance” of the hid light is a phenomenon of instability in the discharge of electrodes during lighting, causing the lights to go out in serious cases and not to work properly
1 maintenance of instantaneous output power of a light, which, when driven by a wave current, gives the output characteristics of instantaneous output power, thereby ensuring that the hil “sound resonance” does not occur。
2 self-protection in an abnormal state of electronic ballast. Automatic protection is provided in the event of abnormalities such as short circuits for the output of light, open circuits for the output of light, failure of light and installation of an overheating environment。
3 lamp output power is constant and consists of two aspects: power voltage fluctuations and constant light output power, and a significant change in light output power over the life of the light bulb as a result of significant changes in hid lamps (especially high pressure sodium lamps). It's only by guaranteeing these two aspects that it's really the constant output of electro-traffic。
Zvs (zero voltage switch), which significantly reduces the voltage current stress of the power unit, was used for the entire electron ballast。
5 to keep the product temperature up within specified values. Thermal design of the internal structure of the entire electron ballast, the selection of ideal heat-dispersion materials, and the effective dispersion of the electrons。
Iv. Price ratios for hid lamps and their applications
It is only with a comprehensive understanding of the application value of hils, their combined economic indicators and their increasing reliability that they will become a reality in practice that the current constraints on the large number of applications of hid lamps have four main aspects: first, reliability, the need to fully overcome the “sonic resonance” that emerges from the hid lights, the fact that the hils are much more complex in their electronic circuit structure than the dhls, and the number of units selected is several times the number of dhls, and therefore the probability of their failure is high. At the same time, the country currently has a large number of hid light bulb producers, with varying standards of light bulbs, which are not well-matched with electronic ballasts, which also reduce their usefulness, and which require strict screening of metaphones by electronic ballast producers to improve product reliability. The second is the requirement for the use of the environment in electronic ballasts, which makes the design of lamps more demanding, making it difficult to install integrated lamps that are currently being developed in large numbers, mainly because they generally require temperatures below 55 °c in the working environment, keeping the temperature of the electronic ballast shell below 75 °c to ensure the operational life of electronic ballasts, so that they are designed in such a way as to have a good dissipation effect and require close cooperation from their peers. Thirdly, the dissipation of large power electrostatics is an important factor affecting the lifetime of electronics, and therefore the design of functional high power electrostatics has yet to be perfected. The fourth is price, which, despite its combined economic benefits, is not currently widely accepted by clients because of high one-time investments. Moreover, to improve reliability, prices will inevitably increase significantly. However, with the rapid development of electronic technologies, these problems will continue to improve, and hid light electro-traffics will be given wide attention and application as green lighting appliances。
Summary
Hid electro-voltagers with good lighting parameters, their combined economic efficiency and the reduction of pollution of the electricity grid will contribute significantly to the achievement of the green lighting project in the country, which is an effective measure to achieve the 10 per cent energy-saving goal as soon as possible. It is therefore believed that, like electronic tradators such as energy-efficient lamps and sun-lights, the hd lamps will be rapidly applied. The use of the china electric power company's electronic ballast product on a number of roads, both inside and outside the country, shows that the product not only has a significant energy-saving effect, but also can significantly prolong the life of the light bulb and is popular with users。
