HID xenon lamp for electricity requirements[汽车基本知识]

HID xenon lamps need hundreds of volts to maintain discharge when working, and 23000 volts when starting, relying solely on 12V or 24VcarIt’s impossible for batteries to light this kind of lamp, there must be a special kind of electrical applianceAccessoriesConvert 12V or 24V car battery power to HID xenon lamp lighting power. This electrical accessory is commonly known as electronic ballastStabilizer. When the voltage passing through the bulb is between 70V and 110V, the ballast will produce 35W of output power. When this voltage is too low, the ballast must supply at least 0.5 amperes of current, but in principle it should not exceed 2 amperes. In theory, it should be as close as possible to 35W. A higher current input is still more feasible. In fact, the HID xenon lamp cannot work normally under the condition of too low input current. Generally, the working principle of the HID xenon lamp is that it needs to continuously provide electricity until about 35W to ensure sufficient output light energy. Only in this case can the characteristics of the xenon lamp be reflected. After the xenon lamp is warmed up, the maximum input current cannot exceed too much, otherwise it will cause damage to the bulb. Only at the beginning of startup or when the bulb fails to work, the voltage passing through the ballast will exceed 110V. The ballast must have enough power to ensure the heat of the lamp, and it is acceptable to exceed 35W. However, excessive power input can cause the aging bulb to burst. Most HID xenon lamps use alternating current, and some can also use direct current, but the premise is that the bulb is cooled. The mixture of direct current electric field, hot quartz, hot glass and alkali metals is not a good combination, and it will cause the lamp tube to break and other consequences. The HID xenon lamp can not input excessive electric energy, except in the initial stage of accelerating the warm-up phase. Excessive power input can cause the bulb to break or at least consume the life of the bulb. However, insufficient energy is not good. If the electrode is not hot enough, it will not be able to complete the high-pressure reaction to make the bulb glow. Too little cathode input will cause the positive ions in the tube to fail to reach the required speed, so it cannot work normally. Under the circumstance of declining electric energy, it is not recommended to install and use HID xenon lamps. In addition to the fact that the positive ions cannot reach the predetermined speed, other chemical reactions in the tube will not proceed normally, which will hinder the normal operation of the bulb. Because for HID xenon lamps, AC power should be used under normal circumstances. Automobile related knowledge ·summerWater tankWhat to do if the water boils[夏季汽车养护]
