HID can be said that since listing, mixed, and its ability to significantly reduce the high light the dangers of night driving, but not well-designed products, but also the formation of a great car right right has always been the threat of recession, color temperature, the failure rate high, life is not long, are common complaints on the issue of the network, and we will tell you where the real reason for these shortcomings.

1 glare serious problems are actually the fault of the manufacturer

Network on a bunch of people in the discussion of the HID to illuminate your driveway completely invisible in front of traffic! In fact, I had a similar experience, but why the original configuration of the HID lamp is no problem? Original HID lamps will not only not glare, and even lighting range, HID brightness wise, than many commercially available, which in addition to HID lamps with halogen and the general body design of the different, the most important reason is that the vast Most HID KITS manufacturers did not make quality work.

HID and halogen bulbs "light-type" difference, which we should have heard, because the tungsten halogen bulb is burned to produce light, while the HID is based on burning electric arc jump "iodide" to light. The former is designed to be straight coil-shaped tungsten wire, which is showing a curved arc of the state (light-emitting height will be more 0.5mm), the emitted light uniformity and color temperature are different, the burning issue of tungsten 3000K light is all about yellow, but the top of the HID lamp high color temperature of light is white, the bottom of the light due to the need through more halogen gas, thus also showing excellent low-temperature yellow.

Although the two different types of light, but if the center of the lamp axis positioning is correct, then the modified class of HID Xenon lamp that produces glare can be reduced to the minimum extent of the range. However, the premise must be HID xenon lamp light falls exactly the center of the luminous center of light. Currently on the electronic game produced APOLight Haibin Awa Wright HID xenon lamp, xenon lamp used in all imported capillary, so the center of xenon lamp light is very accurate and light-emitting center of the original car is consistent, so many users feel APOLight HID xenon lamp Awa Wright did not like the other inferior brands of HID xenon lamp so serious glare (which is often said that the problem of astigmatism).

2 color temperature higher, the better is a great misunderstanding

In general halogen bulbs, for example, its intensity is about 1450Lm (lumens), 4300K ​​bulbs 3200Lm, 5100K bulbs 2700Lm, 6000k bulbs about 2500Lm, but 10000K bulb illumination is almost its only 2000Lm so, than a full 4300K ​​bulbs as much as 40% less!

In addition to the brightness is not enough, the penetration is a problem. Wavelength of visible light the human eye is about 380nm (violet) ~ 770nm (red), while the shorter wavelengths of light penetration of its worse, the 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 nights "did not seem to have lights turn on the lights," the situation is for this reason, because the light is reflected off the surface water to.

Replacement of the higher color temperature of HID, lighting the rainy ability to worse! So, if the double-B and other manufacturers, they still insist on using the 4300K ​​(or 5100K, it has been with the United States through the European E Mark SAE certification) of the HID bulb to accommodate a variety of different lighting environments (snow, the rain, etc. ) because that is the case.

Constant current and constant power in different life

Some people often appear to buy the HID lamp does not light, ballast burning conditions, in addition to product quality control may be poor reasons, the most likely factor is 3. Ballast design concepts completely wrong! Currently, there are two ballast design concepts, namely, constant current and constant power, while the latter is the long life of HID can provide the correct design.

A new HID bulb, the distance between electrodes 4.2mm, to jump between the two electrodes electric arc (arc frame scientific name), it must be 23000V voltage electrodes at both ends (after the voltage lighting will be reduced to 85 ± 17V), but with the lighting frequency, time increases, the distance between the two electrodes will be more and more distant, and to maintain the arc voltage jump power, will gradually increase to the 85V 102V.

Voltage level is not determined within the bulb color temperature factors, in addition to the factors affecting the color temperature of the metal halide lamp of different fillings, the glass ball filled pressure (the higher the color temperature, the greater the pressure) is the color temperature of the factors affecting one.

Constant current ballast will continue to supply a stable current, but with the HID tube pressure increases, the overall output power (according to the formula P = VI shows) will be gradually improved by the rating of 35W to 40W or even 45W! Additional power ranging from lead bulb fixture melt, or heavy ballast bulb will burn! The power output of the ballast be taken not have such concerns, the circuit operation will be improved with the control pressure decreases output current, the power consumption of the entire system has been maintained at 35W size. By Philips, Hella, and Spencer electronic system APOLight brand produced by HID, are set to use the power of design.

HID, halogen lamps with different

Reflector headlight design, there are two, one is the MR surface, a curved line is the thing. The former takes the shape of the diamond-shaped reflector, the use of each piece a different angle, the light reflected to the ground, one after another heavy wide lighting area. The material lines parallel to the surface of the light will be sent to all the light shell, lamp shell re-use pattern on the song shot to the light, the average illumination purposes. As the high point of HID light bulbs (halogen bulb higher than 0.5mm), so (light type) and halogen bulbs, or light, whether the diamond surface must be re-designed shell patterns, but as long as the tube axis positioning accurate enough, beam headlight glare can still be, the phenomenon of scattering to an acceptable range.

Actual installation, as long as the HID gas discharge lamp within the group to replace the original car bulbs halogen lamp position, then use the included line group connected to the original car lamp connector and regulator to put it bluntly, is equal to that in the original lighting line Groups across the middle of a regulator, the gas discharge lamp into HID bulbs, nothing more.
