[汽车修理知识]What is a digital xenon lamp ballast

Digital Xenon LampStabilizer In addition to the basic functions of the general analog HID ballast, it also has: overvoltage protection, undervoltage protection, leakage protection, short circuit protection, reverse connection protection, open circuit protection, waterproof, high and low temperature resistance, etc. Beijing 51carThe new generation of bowon brand digital xenon lamp ballasts newly launched by the service center has incomparable advantages over ordinary analog ballasts: 1. Intelligent processing function The constant power of the general analog ballast is controlled by a multiplier in the circuit. When the external characteristics of the xenon bulb are different, the tube pressure will increase due to the increase of the internal resistance of the tube, and the voltage will rise to a certain level. Degree, the xenon lamp will automatically go out. The HID digital bowon brand ballast launched by Beijing 51 Automobile Service Center is to implement different processing methods through programs to adapt to the characteristics of different lamps. This is something that an analog ballast cannot do. 2. Constant power adaptability performance The rated voltage of the xenon lamp tube is 85V plus or minus 17V. The bowon digital ballast can work normally at the lamp voltage around AC60-150V, the power is constant, and it can adapt to the external characteristics of the xenon lamp tubes of different manufacturers at home and abroad without any adjustment, and protect the xenon bulb from damage, so as to ensure the life of the bulb. Extension, while providing great convenience for consumers' follow-up services. However, some ballasts on the market are only suitable for xenon lamps of specific manufacturers. If another type of xenon lamp is used, the output power will differ by 8W-9W, which can easily cause early damage to the lamp. 3. Wide voltage range work Bowon digital ballast can work normally within the wide voltage range of 7.5-18.5, which is far beyond the level of general analog ballasts, and is suitable for installation and use of cars produced by different brands and different years in different countries in the world. When the input voltage is 9-18V, the output power of the ballast can be kept constant at about 35W (plus or minus no more than 2W). 4. Low light consumption. According to the internationally accepted industry standards, the luminous flux of HID products should still reach 60% of the brightness of the new lamp after the service life exceeds 2200 hours, and the HID products with the bowon digital ballast color temperature of about 6000K after the service life exceeds 2200 hours , The luminous flux can still reach 80%, which is higher than the international standard. 5.Electronic interference is small. Today's cars are widely used microcomputer electronic control. If there is electronic interference, it will cause the car computer and varioussensorThe abnormality brings hidden dangers to safe driving, and the bowon digital ballast will let you have no worries at all.
