HID Xenon lights shortcomings real reason 
HID since the market can be said to be mixed, it's ultra-light capability significantly reduces the risk of driving at night, but without the proper design of products, but also for the formation of the car has always been a great threat to the color temperature of the recession, the failure rate high, life is not long, the complaints are common on the Web, and we will tell you where the real reason for these shortcomings. 
     Glare serious problems are actually the fault of the manufacturer 
     A bunch of people on the network in the discussion of the lane they are completely invisible HID illuminate the road ahead! In fact, I had a similar experience, but why the original configuration of HID lamps is no problem? Original HID lamps will not only not glare, even lighting range, brightness should be wiser than many commercial HID, HID lamps that in addition to the general halogen lamp body and different designs, the most important reason is that the vast most HID KITS manufacturers did not make the product quality work. 
     HID and halogen bulbs "light type" is different, this is something we should have heard, because tungsten halogen bulbs are burning to produce light, while HID is based on electric arc jump burn "iodide" to light. The former is designed to be a coil-shaped tungsten wire straight, while the latter presents a curved arc of the state (light emission will be more than the height of 0.5mm), and the color temperature uniformity of light emitted are different, tungsten issued combustion is about 3000K light yellow all but the top of the HID lamp is a light of high color temperature of white light through the bottom to be more due to a halogen gas, and so will exhibit excellent low temperature yellow. 
     While both light pattern is different, but if the bulb axis positioned correctly, the degree of glare produced by HID conversion still within an acceptable range. However, provided that the optical axis of the lamp must be accurately fall lamps emitting center. 
     Color temperature is higher, the better is utter nonsense 
     First, the high color temperature of HID lamp life is relatively short, 4300K ​​lamp life of 3200 hours, 5100K and 6000K lamp is approximately 2000 hours, but up to 10000K color temperature lamp, life has found no information (because light pipe manufacturer does not provide), but according to previous data estimate, its life should be only half of standard products (because 10000K bulb high internal pressure). 
     In general halogen bulbs as an example, its illumination is about 1450Lm (lumens), 4300K ​​bulbs 3200Lm, 5100K bulbs 2700Lm, 6000k bulbs about 2500Lm, but 10000K lamp illumination is almost its only about 2000Lm, than full 4300K ​​bulbs as much as 40 percent less! 
     In addition to bright enough outside penetration is also a problem. The human eye in visible light wavelength of about 380nm (violet) ~ 770nm (red) between the shorter wavelength light and its penetration worse, more difficult to penetrate the water vapor or mist, but prone to the phenomenon of refraction! Previous "ultra-white bulbs" will appear in the rainy night "did not seem to have the lights turn on the lights," the situation is for this reason, because the light is being refracted off the water surface to. 
     Replace the higher the color temperature HID, lighting capability Rainy Day is worse! So, if the pair B and other manufacturers, they still insist on using 4300K ​​(or 5100K, it has with the United States through the European E Mark SAE certified) HID bulb to accommodate a variety of different lighting environments (such as snow, rain, etc. ), the reasons for that is the case. 
     Constant current and constant power different life 
     Some people are buying HID often appear bulb does not light, ballast burned condition, except possibly the cause of poor product quality control, the most likely factor is that the ballast design concept completely wrong! Currently, there are two ballast design concept, namely, constant current and constant power, while the latter is designed to provide the proper HID long life. 
     A new HID bulb, the distance between the electrodes is 4.2mm, to produce electric arc jumps between two electrodes (learn rack arc called), it must be voltage 23000V at both ends of the electrode (after working voltage lighting will be reduced to 85 ± 17V), but with the increase in the number of lighting time, the distance between the two electrodes will be far more, but to maintain the operating voltage of the electrical arc to jump also slowly increased from 85V to 102V. 
     Operating voltage level is not decided within the bulb color temperature factors, factors affecting the color temperature in addition to metal halide lamps in different fillings, glass balls filled pressure (the higher the color temperature, pressure greater) factors also affect the color temperature one. 
     Constant current ballast will continue to supply a steady current, but with the increasing pressure of HID tube, the overall output power (P = VI formula based on known) will gradually increase from 35W to 40W rated or even 45W! Additional power ranging from lead bulb holder meltdown, bulb or ballast weight will burn! And given the power output of the ballast taken there will be no such worries, with the arithmetic circuit riser pressure will decrease the output current size, so that the power consumption of the entire system has been maintained at 35W size. By Philips, Hella and Chun Shun Technology made ​​Maxtel brand produced by HID, are given the power to use the design concept. 
     HID, halogen lamps with different 
     Headlight reflector design, there are two, one is the MR curve, one is the physical wire surface. The former takes the shape of a diamond-shaped reflector, using each piece different angles, the light reflected from the ground, heavy bursting wide illumination area. And the surface thereof will be sent to all of the lines parallel to the light of the lamp envelope, the lamp envelope on the re-use pattern of the emitted light reaches the song, an average illumination purpose. Because HID light bulb high point (higher than halogen bulbs 0.5mm), so the (light type) with a halogen bulb is different, whether it is a diamond surface or light shell pattern must be re-designed, but as long as the tube axis positioning accurate enough, still headlight glare beam scattering phenomena can be reduced to an acceptable range.
