What is the difference between xenon, halogen, LED, tungsten halogen in car headlights

The brightness and penetration of the light are not the same as the chromaticity.

Generally, the service life of halogen lamps is 500 hours, the life of xenon lamps is about 3000 hours, and the service life of LED headlights is still inconclusive, because the current technology is not very mature, but the theory can reach about 50,000 hours. The word "halogen" means that the gas filled in it is halogen (iodine and bromine), which prevents the oxidation of oxygen, and sublimates into gas when the halogen is hot, and becomes a solid attached to the tungsten filament when it cools, improving the service life of the filament (about 4 times).

Xenon bulbs use almost the same light color as daylight, creating better visual conditions for the driver. Xenon lamps allow for a wider range of light and greater light intensity, which greatly improves the safety and comfort of driving. In the case of low beam, the power of a xenon lamp is 35W while that of a halogen bulb is 55W.

If used properly, it is also higher than halogen bulbs in terms of lifespan. However, there are a few things to keep in mind when choosing a xenon lamp. 1.

Don't choose a xenon lamp that is too cheap to use.

Hella ** is the most expensive, the far and near beams are excellent, the Koito near beam is excellent, the tangent is beautiful, **cheap, the legend of the rivers and lakes shines on the wall artifact! There are many stabilizers, Hella, Valeo, Koito ......The more well-known xenon lamps are Philips and Osram! The other is the maintenance cost, my halogen lamp is broken and it is very cheap to replace a small lamp bead, and the xenon lamp has not been broken, I don't know the specifics.

Of course, xenon lamps also have the advantage that they can improve the grade of the car, and everyone feels that it is nothing more.

I now use xenon lamps, and the low beam paving effect at night is absolutely first-class, and the high beam hits out with a piece of light, which greatly improves the visibility and safety of night driving. In addition to the reflection of street signs, halogen lamps feel bright, and their paving and lighting effects are extremely poor, and it is similar to not turning on the lights in rainy days. There are advantages and disadvantages, according to the current situation of haze in our country, we should set up a dual system, turn on the halogen lamp on a foggy day, and turn on the xenon lamp on a sunny day.

In the original headlight adjustment set up a switch (press is one, jump is one), the light box is equipped with two sets of lights. The voltage upgrade box is in the front of the car, so it does not affect each other.

Like halogen headlights, it is equivalent to some incandescent lamps with a particularly short lifespan, and it is easy to blacken, the cost is very low, and the production is also very simple. The light emitted is basically yellow. Xenon headlights.

Its voltage is very high and can reach 23,000 volts. It's about 5 times that of halogen headlights, but it's also very hot and consumes power very quickly. Startup is slow.

Like the LED headlights, they have a cool appearance and a wide range of brightness. It can illuminate a large area of many things, and it is also very popular.

Halogen headlights, like incandescent lamps, have the strongest penetration in rainy and foggy days! The difference between xenon headlights and halogen headlights is that there is no filament, and xenon headlights have the same light color as daylight, so the visual effect is good!

The cost of halogen headlights is low, the production method is very simple, the penetration is relatively good, the life of xenon lamp is very long, and its brightness is also very high, the life of LED headlights is also very long, and it is very power-saving and environmentally friendly.

Halogen headlights refer to quartz lamps; The difference between xenon headlights, LED headlights and quartz lamps: different structures, different characteristics, and different principles.

First, the structure is different.

1. Xenon headlights: Xenon headlights have no filament, and their heat dissipation performance is better.

2. LED headlights: lighting appliances made by using solid semiconductor chips as light-emitting materials and LEDs as light sources.

3. Quartz lamp: It is composed of filament, glass lamp shell, internal and external power supply leads, etc. The bulb glass shell is made of hard quartz glass, the glass shell is small, the air pressure of the inert gas inside is higher, and the working temperature of the filament is also higher, so the luminous efficiency of the quartz lamp is higher, and the effective life is much longer than that of the general incandescent bulb, up to more than 3000h.

Second, the characteristics are different.

1. Xenon headlights: high light intensity, low energy consumption, xenon bulbs use almost the same light color as daylight, creating better visual conditions for drivers.

2. LED headlights: It can overcome the aging effect of ultraviolet light on plastics, and has the performance of changing the color of luminescence.

3. Quartz lamp: **expensive, continuous light, soft and warm effect, extremely accurate lighting, and extremely bright color.

Third, the principle is different.

1. Xenon headlight: use the arc generated by the discharger between the two electrodes to emit light.

2. LED headlights: direct light emitting light through photon emission caused by the recombination of carriers.

3. Quartz lamp: Contrary to the light source of the flash lamp, it can be used to obtain more detailed colors in a slow light-sensitive way.

Halogen lamps are common bulbs in ordinary cars, which are cheap, heated, have a relatively short lifespan, and have average brightness.

Xenon lamps have high cost, high brightness, low power consumption and long life, and are used in high-end cars, and even some are used in high and near beams, but they need to be used with lenses, such as Guangben, Citroen, etc.

LED is popular in recent years, high brightness, low energy lighting, single LED brightness is not enough to provide the main light source, so it is generally connected in parallel or as tail lights, turn signals.

The ordinary headlights we are talking about are halogen headlights, and the LED lights are diodes, which have a smaller chance of damage and higher brightness, but if they are damaged, then the cost is also higher.

The brightness of this LED headlight is higher, and it is power-saving and environmentally friendly, and the failure rate is low.

Car bulb is a car driving at night to ensure driving safety, lighting the road bulb, car bulb for you and your family to bring safety and comfort in the drive, car bulb belongs to car supplies, car products will focus on car supplies service, poor lighting conditions are easy to cause eye fatigue, but also can not provide the driver with effective illumination brightness and area, good car bulb can provide you with higher brightness and better vision, but also improve the comfort and safety of driving, ensure your driving safety, so that driving confidence.

Directions for use. 1. Respond to the phenomenon of light decay and take the initiative to replace the car bulb.

With the use of car lights, the brightness of the bulb gradually decreases, and this normal physical phenomenon is known as light decay. Dimming the lights can easily cause accidents, so once the lights are dimmed, they should be replaced in time, not until they are broken. Choosing a high-quality bulb can delay color decay, extend the service life, and provide more assurance for your driving safety.

Check your lights regularly and recommend that you replace them in pairs every 20,000 km.

2. Choose a safe and effective car bulb.

Color temperature determines the color of light, the original supporting lights are basically yellow, appropriately increase the color temperature, you can get a more fashionable white light and a more comfortable driving experience, but not the higher the color temperature, the better, if the color temperature exceeds 6000K, the penetration of light decreases, which is not conducive to driving in rainy and foggy weather, so for your driving safety should choose a safe, effective color temperature of the car bulb.

3. The bulb can be replaced only after the engine is turned off for 5 minutes.

Before replacing the car light bulb, gloves and protective goggles are required, use alcohol to wipe the handprints or grease on the outside of the light bulb, and do not touch the glass surface of the bulb with bare hands to prevent fingerprints from staining the glass case and shortening the life of the bulb. Lights should be adjusted after replacing the bulbs to avoid glare.

Do you know the difference between halogen, xenon, and LED headlights? Check it out.

The difference between xenon lamps and halogen lamps is quite big, and low-end models are equipped with halogen lamps, because halogen lamps are cheaper, and xenon lamps only appear on mid-range models, which are more expensive.

Halogen bulb, referred to as halogen bulb or halogen bulb, also known as tungsten halogen bulb and quartz bulb, is a variant of incandescent bulb.

Xenon lamps are also called HID gas discharge headlamps in the field of automotive lights. It replaces the traditional tungsten filament with high-pressure xenon gas encapsulated in a quartz tube, providing higher color temperature and more concentrated illumination.

1. Different color temperature: the color temperature of xenon lamp is determined by the composition of the pill in the bulb, and now the color temperature of xenon lamp varies from 4000k-8000k, and there are some choices, of which the color temperature of about 5500k is positive white light, and the illumination effect is good. The color temperature of the halogen lamp is not chosen, it is all 4300K, the color is yellow, and the illumination effect is not good.

Second, the brightness is different: the 35W xenon lamp lumens can reach about 3500, and the 55W halogen lamp lumens are only about 1000.

3. More energy-saving: 35W xenon lamp is brighter than 55W halogen lamp, and the power used is smaller and more energy-saving.

Fourth, the service life is different: the service life of halogen lamps is generally about 1 year, and the service life of xenon lamps is generally about 4 years.

1. The structure is different. Halogen bulbs have filament, while xenon lamps do not have filament. Halogen lamps emit light through tungsten filaments, while xenon lamps emit light using an electric arc generated by the discharger between the two electrodes.

2. The brightness is different. Xenon lamps have three times higher light intensity than halogen lamps and have a wider light range, which greatly improves driving safety and comfort.

3. Different energy consumption. The energy consumption of xenon lamps is two-thirds of that of halogen lamps, and the energy saving effect is obvious. The xenon lamp is only 35W, while the light emitted is more than 55W halogen lamp, which greatly reduces the load on the car's power system.

4. The service life is different. Xenon lamps use electrons to excite gas to emit light, and there is no tungsten wire, so it has a long lifespan and can be used for about 3000 hours; Much higher than ordinary halogen lamps.

1. The cost of halogen lamp is more reasonable, the illumination is sufficient, and the time to reach the peak brightness is short, and it has its irreplaceable advantages when used as a car high beam, but this lamp is powered by filament. The filament is prone to fusing at high temperature for a long time, and the failure rate is high, while the xenon lamp will not be extinguished instantaneously once it fails, but is extinguished by gradually dimming, so that the driver can win time in the dark driving and pull over urgently, and the xenon lamp is more power-saving than the halogen lamp, and the life is longer than the halogen lamp. However, xenon headlights do not have good light concentration and sometimes cause automatic flameout.

2. Xenon-based headlights because of their physical reasons, the penetration of the lights is not very strong, and it is easy to be dangerous, and it takes three seconds to reach the full brightness, so according to China's regulations, it is forbidden to use xenon headlights in automobile headlights, but they can be applied to the low beam of automobiles. If it is necessary to install xenon headlights, lenses must be added. If Lingfeng Mountain is not equipped with lenses, it will produce serious scattering, which will seriously affect the line of sight of oncoming vehicles.

3. In fact, the halogen lamp is much stronger in terms of penetration, and it has strong penetration, especially in rainy and foggy weather, but it is definitely incomparable to the higher-level LED lamp, and the penetration of the LED lamp is stronger than that of xenon lamp and halogen lamp.
