Xenon lamp bulb model shadowless colonoscopy CS17- (φ40,25W, 24V) www.tsgb120.comwbwswy1802537228 the current to stimulate gas light, lower temperatures and produce no filament, as long as the neon has not run out, you can always normal light , very difficult to damage. In the latter part of the life of the xenon lamp, the light emitted gradually weakened, has also been prompted in advance. Original article: how high quality halogen bulb, the most they can for 400 hours of continuous use, and the use of gas lamps glowing gas atmosphere, at least have a service life of 2500 hours, that is at least five times the product life. A group of Xenon gas discharge lamp group enough to spend six years. Approximately electricity consumption by vehicles halogen headlights most original takes about power, xenon gas discharge headlamps set in a stable operation of the ballast, an average of only 35: power to supply xenon lamp light bulbs, indirect savings a gasoline this valuable energy. Without "wife" before ammonia lighting of vehicles, original car headlight Xenon lamp adapted for modified car in the secondary market has become a hot topic. Plus "first wife" before Xenon car lighting more widely, so that the xenon lamp lights replace the halogen gas atmosphere, will become the new trend in the 21st century former vehicle lighting. Xenon lamps have many excellent properties, but also has some drawbacks, the most important is its negative incremental resistance characteristics, so they need to use an electronic ballast to make it stable. Currently most of the use of electronic ballasts initiative to obtain a stable voltage regulator plus a high power factor and xenon lamps required, electronic ballasts already have a compact size advantage, however, if the low-power electronic ballast in can use single-stage switch, it is bound to get improvements in streamlining and cost of the circuit. People more research 220V power input of electronic ballasts more than 12V battery system is not suitable for the power supply of the product. Advantages related art electronic ballast electronic ballast high-intensity discharge lamp and ballast must be connected in series to stabilize the work to overcome the "negative resistance" characteristics. High reliability and long life are advantages of magnetic ballasts. But inevitably there are shortcomings in the following areas: (I) the power factor is low, usually around 0.4; (2) heavy, bulky, loss, noise, supplies more; (3) power stability is poor, grid voltage changes, while the lamp power varies with; (4) frequency lighting, low efficiency, there is no stroboscopic phenomenon. This lighting system has not satisfied people's quality Xenon lighting systems. In 1963, that "electronic ballast" thinking. 1970s energy crisis worldwide to promote the development of electronic ballasts, many companies began to study the new energy-saving electric light and fluorescent electronic ballasts. As semiconductor technology, especially the rapid development of power electronics technology, a variety of power switching devices continue invention is applied, so that the exchange of electronic ballasts for "commodity" possible. In 1978, the Dutch company developed the first successful use of the fluorescent element 162 high frequency electronic ballasts, which is a major innovation in the history of electrical lighting. Into the 1990s, people began working to popularize electronic ballast to high-intensity discharge lamp field. The basic principle is that electronic ballasts, the first frequency AC power rectifier into DC, then a high-frequency electronic components whose conversion circuit, "inverter" for the high-frequency voltage and high frequency alternating current, the inverter and the point after to start bright fluorescent light. For without the lamp power characteristics, electronic ballast and the lamp can be matched exactly to meet different power xenon lamp starting voltage, lamp voltage and lamp current, to achieve the best work. Compared with the ballast, electronic ballast has great advantages of a high efficiency. Since light efficiency with the operating frequency increases and increase, decrease with the light of the electronic ballast input power; its low power consumption, which is about the lamp power (compared with magnetic ballasts reduce clever; electronic ballast manifold drive and high power flow saving effect is more significant; 2, line power factor improvement (produced by magnetic ballasts 0.5 up to 0.9 and a corresponding increase in the utilization of the power grid, energy-saving high luminous efficiency to achieve indirectly generate little heat; 3, no starter Eliminates time and replacement costs; 4, no flash, light and soft, good to protect their eyesight: Start fast, there are no repeated ignition, flicker preheat start function, greatly extend the working life of xenon lamp quiet, no noise. improve the quality of the lighting environment. Ease of intelligent and networked control and to achieve development .2 dimming electronic ballast technology, electronic ballasts increase the operating frequency to reduce the volume of the ballast element, eliminating noise while improve the discharge lamp light efficiency, and low-frequency flicker can be properly resolved the problem. power electronics, microelectronics and electric light source technology continues to evolve, the electronic ballast circuit topology, the study of depth and intelligence, etc. has made substantial progress, for example, electronic ballast power factor can reach, etc. At present, the electronic ballast technology research, mainly in specialty lighting, improve lighting quality, improve lighting environment, reducing power pollution, remote control, tune Light and intelligent several aspects of electronic ballasts can be divided into several stages of the first generation: ordinary type X-type legs correction www.oxleg.com bandy legs correction 8,695,712,255 electronic ballast, the production of the late seventies It is the transition of low to high frequencies product most simple electronic circuit, single function, the lack of reliability and consider the impact on the grid poor electrical performance: Functional factor is less than 0.6 current harmonic content up to the second generation: passive filter "High Power Factor electronic ballasts "In the first generation, based on standard and GB production. employing passive filtering technology and power factor correction circuit to improve power factor inhibiting harmonic content, and design warm start, abnormal state protection and other functions , ballast performance and reliability have been greatly improved, with a simple circuit, low cost, there is a strong market competitiveness.
