Why Must Xenon Lamps Be Replaced After Several Years of Use?
1 Answers
Xenon lamps must be replaced after several years of use because they typically experience light decay within approximately 2 to 4 years, which can compromise driving safety. Therefore, it is advisable to replace xenon lamps soon after signs of light decay appear. The illumination principle of xenon lamps involves a quartz tube filled with xenon gas inside. High-voltage current activates the xenon gas to create an arc light. Xenon lamps have a high color temperature, appearing more white, with their greatest advantage being brightness—up to three times brighter than halogen lamps. The lifespan of xenon lamps is also significantly longer than that of halogen lamps, lasting approximately 2,500 to 3,000 hours. Installation Precautions for Automotive Xenon Headlights: Avoid installing them in areas prone to excessive heat inside the vehicle. Avoid installation near water sources, as excessive moisture can lead to leakage and aging of the ballast. They should be placed in well-ventilated locations to allow air circulation and reduce the temperature of the ballast. The distance between the ballast and the bulb should not be too far to prevent voltage drop in the circuit, which could cause the bulb to fail to light. The high-voltage wire section of the ballast should not be coiled to avoid generating excessive magnetic fields that could interfere with other electrical devices in the vehicle. Replace the original 10A fuse of the headlights with a 15-20A fuse to prevent the original fuse from blowing due to excessive current during startup.
