Why did the xenon lamp be changed and the light diverged?

Many of the riders switched directly to the xenon lamp at the original headlights and found the lights diverging. When I opened the light, I looked very stare at the other side. I could not see the road clearly in the car. There are many reasons for astigmatism after the direct modification of xenon headlamps. The most critical factors are two:

1. because of the installation process or the physical parameters of the bulb, the focus of the headlamp is offset. Since the center of the modified xenon lamp light source deviates from the design of the center of the halogen lamp bowl, the astigmatism inevitably occurs. In the same way, when the center of light is shifted around, there will also be a phenomenon of spotlight.

2. the wavelength of light changes, so that the lens parameters do not match the wavelength of the light source. The second reason for the modification of HID Xe Xe astigmatism is due to the large difference between the main spectrum of HID and the original halogen, which is caused by poor focusing. However, in general, the refractive index varies little with the light wave in the visible range. Therefore, the main reason for the dispersion of HID xenon headlamps is the displacement of the light source.

Only by understanding the reason of xenon lamp astigmatism can we solve this problem in essence. Some refitted shops do not consider the structure of light source. The focal points of light bulbs are matched and adjusted directly. They do not test whether the focus is correct and whether the height of the lamp is reasonable. The result of this modification is certainly not ideal, and even there are hidden dangers. It is recommended that the car friend refitted xenon lamp to find a good technical force and a good reputation store. Otherwise, the cost will be worse than that of the original lamp, and there will be a hidden danger of driving safety.
