l, the principle of XENON headlights
The full name of xenon headlights is HID gas discharge lamp. Its luminous principle is to stimulate the chemical reaction between xenon and rare metals by positive and negative electricity, so you will find a small glass ball in the tube of the HID bulb, which is filled with xenon and a little rare metals. As long as they are stimulated by current for chemical reaction, they will emit light with a color temperature as high as 5K K. This is not only the brightness that traditional halogen lamps can't achieve, but 5K is actually the closest to the color temperature of noon sunlight and the most comfortable brightness for people's eyes. In addition, because the activity of xenon molecules will become more active with the increase of service time, the gas discharge bulb will become brighter and brighter with the use.
However, the tungsten lamp can make it glow with a voltage of 12 volts; If it is used to stimulate xenon to emit light, it is absolutely not enough. Therefore, a real HID gas discharge lamp should have a voltage stabilizer, and the voltage of 12V should be boosted to 23, V, which can be used to stimulate xenon to shine at the moment when the power supply is just 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
It is usually called "Lumen" in the unit of calculating brightness. Xenon headlights can output brightness as high as 35Lumen, while general halogen bulbs can only produce brightness up to 1Lumen; 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 fog.
3, high color temperature comfort
As mentioned earlier, xenon headlights can produce color temperature light of about 5K, 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 of light produced at what temperature. The lower the temperature, the more red the color temperature light will be, while the color of light around 5K is just the whitest color temperature that starts to turn blue slightly, and it is also the closest to the color of noon sunlight, and the human eye has the highest acceptance and comfort. This kind of light can effectively reduce the driver's visual fatigue and indirectly contribute to driving safety when it is used in the night lighting of vehicles.
4, several times the product life
Everyone may have encountered the situation that the halogen lamp in the car suddenly fails to light up, and the tungsten wire is burnt out as a result. Indeed, because the luminous principle of halogen lamps is caused by the heating of tungsten wires, it is difficult to ensure that tungsten wires will not burn out and be damaged under long-term high heat; Xenon lamp uses current to stimulate gas to emit light, which basically does not produce too high temperature, so as long as the xenon in it has not been used up, it can always emit light normally and is not easy to be damaged! According to a study, even a halogen bulb with high quality can only be used continuously for 4 hours at most; Xenon bulbs that use gas to emit light have a service life of at least 3 hours, which means that a set of HID gas discharge lamps is enough for you to use under normal car conditions!
5. About 1/2 power consumption
Most halogen headlamps in general vehicle factories need to consume about 6W power, while some brands of HID gas discharge headlamps only need 35W power to supply xenon bulbs to emit light under the stable operation of ballast. As for the electricity saved, doesn't it mean indirectly saving gas money?
comparison of imported "Vision" HID xenon lamp system with general halogen lamps:
general headlights (halogen) VIOS HID headlights (xenon lamps)
power consumption: 5-1 watts, 35 watts
brightness: 133 lumens, 35 lumens
life: 35 hours, 2-3.
