L, the principle of xenon headlights
The full name of xenon headlamp is HID gas discharge lamp. Its luminous principle is that xenon reacts with rare metals by positive and negative electricity, so you will find a small glass ball in the tube of HID bulb, which is filled with xenon and a little rare metals. As long as the chemical reaction is stimulated by current, it will emit light with a color temperature as high as 5000K, which is not only the luminosity that traditional halogen lamps can't reach, but also the luminosity closest to the midday sun. In addition, because the activity of xenon molecules will become more active with the increase of use time, gas discharge bulbs will become brighter with use.
Tungsten lamp can make it glow with a voltage of 12 volts; If it is used to stimulate xenon luminescence, it is absolutely not enough. Therefore, a real HID gas discharge lamp needs a voltage regulator to boost the voltage of 12V to 23,000 V, which is used to excite xenon to light up at the moment when the power supply is turned on, so as to stably and continuously supply xenon bulbs to emit light.
Let's explain in detail the attractive features of HID xenon headlights:
2. Triple brightness output
Usually the unit for calculating brightness is called "lumen". Xenon headlights can output brightness as high as 3500Lumen, while general halogen bulbs can only produce brightness as high as 1000Lumen. The brightness efficiency of HID is three times higher than that of traditional halogen lamps, which has obvious effect on improving the visibility of driving at night and in foggy days.
3, high color temperature comfort.
As mentioned earlier, xenon headlights can produce color temperature light of about 5000K, but most people have a wrong idea that the higher the K value, the brighter it will be. In fact, the so-called color temperature only explains the color produced by light at what temperature. The lower the temperature, the redder the color temperature light will be, and the color of light around 5000K is just the whitest color temperature that starts to turn blue slightly, and it is also the color closest to the noon sunshine, and the human eye has the highest acceptance and comfort. When this kind of lamp is used for vehicle night lighting, it can effectively reduce the driver's visual fatigue and indirectly contribute to driving safety.
4, several times the product life
Everyone may have encountered a situation in which the halogen lamp in the car suddenly failed to turn on, and the tungsten wire burned out as a result. Indeed, because the luminous principle of halogen lamp is caused by the heating of tungsten wire, it is difficult to ensure that tungsten wire will not burn out under long-term high heat; Xenon lamp uses electric current to stimulate gas to emit light, which basically does not produce too high temperature, so as long as the xenon gas inside is not used up, it can always emit light normally and is not easy to be damaged! A study shows that even high-quality halogen bulbs can only be used continuously for 400 hours at most; Xenon bulbs that use gas to emit light have a service life of at least 3000 hours, which means that a set of HID gas discharge lamps is enough for you under normal car conditions!
5. The power consumption is about 1/2.
Generally, most halogen headlamps in the original car factory need to consume about 60W, while some brands of HID gas discharge headlamps only need 35W to supply xenon bulbs to emit light when the ballast works stably. As for the electricity saved, isn't it indirectly saving gas money?
