Want to change the car lights, which is better, LED or xenon lamp? Is there anything to pay attention to?

First of all, let's talk about some requirements for annual inspection.

1, the light brightness is too dim, and it is not safe to see the road in the dark, so it is not allowed to pass the annual inspection.

2. The brightness of the light is too bright and dazzling, which will affect others to drive. It's not safe. It can't pass the annual inspection.

3. The tangent of light is not up to standard, and the angle and range of light irradiation are quite different.

4. The xenon lamp with high-voltage bag and ballast has been modified (this is generally because the ballast is outside the lampshade. In some places with strict annual inspection, it is illegal to modify the front shell if the lid is opened, and it is not allowed).

To sum up, if the xenon lamp lens assembly is replaced, there is a certain probability that it will not be allowed.

In the previous question and answer, I talked about three main ways to upgrade headlights, which vary from car to car.

Halogen lamps are too dim. To upgrade brighter lights, we must first look at what car the owner is, and different cars adopt different upgrade methods.

There are three main ways:

The first type: upgrade LED headlight bulbs.

For riders who have lenses in their original cars, the simplest and most worry-free way is to change the LED headlights and replace the light bulbs directly. Simple and convenient, with suitable brightness and color temperature. Most of them will not affect the car inspection.

The second type: change the high-brightness xenon lamp bulb.

Compared with LED, the brightness is similar, but compared with upgrading LED, upgrading xenon lamp requires adding a decoder and installing a high-voltage package, which is a little more troublesome. Because these things are not put in the lampshade, some places are not allowed to pass after checking and opening the lid.

The third type: change the lens and change the assembly.

For riders without lens headlights, if slight astigmatism is acceptable, they can also change to a better LED bulb, which is not too expensive and easy to install.

If it is not acceptable, then we should add a lens or even replace it with a component. There are many changes, such as LED double lens and xenon lamp double lens. In this case, it is more troublesome and expensive, but the effect is really good. For some old cars, it is not recommended to exchange them for new ones. The assembly of the original car is not the best, but it is suitable for the original car itself

No matter what kind of LED headlights or xenon lamps are upgraded, safety is the first. While ensuring your own driving safety, you should also be careful not to replace headlights that are too cold and have too high color temperature, otherwise it will affect others' driving sight. So, is upgrading LED headlights and xenon lamps better than halogen lamps?

That may not be true.

Let's start with the xenon lamp. The development of xenon lamp has been relatively mature, but the shortcomings of start-up delay and high temperature and high pressure still exist.

In most cases, it is necessary to add a lens to the xenon lamp. Although the brightness is high, but the cost is high, it will inevitably break the line and change the total amount. It is recommended not to change the xenon lamp with too high color temperature, which is too dazzling and unsafe.

Let's talk about LED headlights. At present, the LED headlights on the market are uneven and varied, and many LED headlights are actually unusable.

First of all, the brightness is not as high as advertised. Just because the LED has a high color temperature, it is white and blue and looks brighter.

Secondly, the LED does not dissipate heat well. Even if it is quite bright just bought back, poor heat dissipation will also lead to a sharp shortening of LED life and serious light decay.

Finally, LED headlights generally have astigmatism, which causes the light emitted to affect the sight of the opposite driver and is not conducive to driving safety.

So, what kind of LED lamp is worth choosing? What should I pay attention to when choosing LED lights?

A good LED lamp must first dissipate heat, ensure the temperature, brightness and life, and make the lamp as good as new.

A good LED lamp must have a good spotlight, even if it is not as clear as the tangent of the original halogen lamp, it cannot be scattered into a lump without the tangent (for a car with a lens, good spotlight mainly focuses on heat dissipation and brightness).

As long as these two points are achieved, then this LED lamp will be good.

This is a LED headlight worth seeing, and its brightness is comparable to that of xenon lamp. The pre-sale of JD.COM 2065438+091.9 has started, and the evaluation of old drivers of various models has also been carried out. For the sake of driving safety, you can learn about it.

Yes, but you must change it with lenses. It is understandable that you want to change headlights, because you want to improve driving safety and lighting quality! But there are many places to pay attention to! Xenon headlights are already a very backward lighting type, with slow starting response, high temperature (poor wiring, easy spontaneous combustion), high installation technology, understanding of circuits and external boxes, low safety, high energy consumption and short life! LED has obvious advantages, long service life, low temperature, no need to plug in, original factory interface, low energy consumption and instant start (I will tell you that xenon is good when I go to the car light modification shop, because it is too large to sell)! When buying LED bulbs, you must not be greedy and cheap. You must buy products from regular manufacturers. Mainstream brands include OSRAM, Hella and Philips. Check the original model of the light bulb and buy it in official website. When buying, pay attention to buying a fan at the tail, and don't buy a copper belt for heat dissipation. Brightness is 4000, which is unnecessary. It is better to have high brightness and high penetration. To tell the truth, even if it is far away, it is useless. Because your vision is limited to 300-400 meters at most, and the higher the brightness, the less clear it is in rainy and foggy days, because the water vapor in the air will reflect cold light (the advantage of halogen is reflected). All you see is white! In addition, it is recommended to upgrade only the low beam, and it is best to keep the halogen lamp for the high beam! Halogen lamp has obvious penetrating power, and is suitable for high beam. It hardly reflects light in rainy and foggy days!

If the built-in lamp is replaced, it is recommended to use xenon lamp, mainly because the light emitting point of xenon lamp is very close to the tungsten lamp of the original car, which will not change the focus position, and the range and width of light are close to that of the original car, which will not affect the paving lighting effect, and the lumen number is higher than that of ordinary built-in LED. However, LED emits light on one side, and there is a bottom plate or radiating column on the bottom plate, so it will affect the focusing position in the original car lampshade, resulting in poor focusing, and the lighting effect of pavement will be reduced if the light is too scattered, too close or too concentrated, especially for a double bulb like H4, which cannot match the position set by the original factory, and the astigmatism phenomenon will be very serious, which cannot be solved by the current technology. In addition, the color temperature of high-power LEDs is generally too high, which is also the problem of xenon lamps, and the color rendering is not high. However, the heat dissipation pressure of high-power LEDs is too high, and the fan can not fully guarantee to meet the heat dissipation requirements. If you want to be stable, it is recommended to use xenon lamp. Or replace the tungsten lamp with higher power, but it is recommended to replace the headlight circuit to match at the same time. Or just add an external light as an aid, which will have a good effect.

Finally, no matter what kind of lamp is used, it is necessary to ensure that the color temperature of the light is lower than 6000K and the light beam is not too high. If the beam is too high, it will not illuminate the road, but will affect the road lighting of the opposite driver. It's called harming others and yourself, and the loss outweighs the gain.

I think changing the lamp still depends on the budget, the original lamp and the acceptable damage degree of the car.

1. If the budget is average, and then the original halogen lamp is used, but you don't want to make big changes and destroy the original structure of the lamp, you can choose the in-line LED. This kind of LED headlight looks like a halogen lamp, that is, the luminous principle is not halogen, but LED chip. You can get an appearance of about 1000. It is a very good choice to upgrade LED directly with halogen lamps without modifying headlights.

2. If local tyrants have a budget of 5,000 to 6,000 yuan and are not afraid of big changes in their cars, then they can choose xenon or integrated LED. In fact, the effect of the two is not much different, and the price is not much different, that is, LED may have some advantages in energy saving and psychology. After all, LED is the mainstream car light at present.

My golf 7 was originally equipped with halogen, but later it was replaced with direct-entry LED headlights. I chose Osram Fast Light to replace the LED headlights. After the upgrade, the effect is very satisfactory. Less than 1 ,000 yuan, said that I can do DIY myself, but my hands-on ability is not good. I went to the store, and the master helped me install and debug it for 10 minutes, which was much faster than changing xenon lamps and integrating LEDs. It took at least four hours.

LED and xenon lamp are two kinds of lamps, both of which are not good, but they are different in different aspects.

Xenon lamp lumen performance is better than LEd lamp, LED is energy-saving and environment-friendly, and DC drive is stable. In terms of color temperature, both are similar, from 4000 K to 6500 K.

For xenon lamp, it is the best lamp with the best lumen at present. If you want to pursue the lighting effect of the lamp, it must be a xenon lamp. Its lumen can reach about 3200lm, but the LED is only about 3000, which is quite poor. In addition, in terms of safety, the xenon lamp will not go out instantly, but will go out gradually, which can give the driver sufficient reflection time and is still guaranteed in safety.

The biggest advantage of LED is that it is quite energy-saving, because it uses solid-state light source and is driven by constant current, so the power consumption is relatively low. Solid-state light source directly converts electricity into light without generating heat and radiation, which belongs to green lighting LED light source. Because it is driven by constant current, it has good stability.

Individuals can use LEd lights, green lighting, solid-state light source, constant current drive, stability, long life, higher than Chen Ben.

Replacement of xenon lamp is not recommended:

Reason 1: Xenon lamps can only be installed after the original vehicle line is destroyed, and it is difficult to restore the original vehicle condition after the annual review.

Reason 2: After replacing the xenon lamp, it is difficult to change it from xenon lamp to halogen lamp or LED headlight, because the original line and voltage have been changed.

Reason 3: Xenon lamp is a high-voltage light source, which has hidden dangers to the original car.

Reason 4: Xenon lamps start and switch lamps are delayed, while LED headlights are not.

To sum up, LED headlights are more recommended.

Why do many people choose LED bulbs?

Answer this question first.

1: strongly promoted by manufacturers. Driven by the interests, manufacturers and various modification shops make great publicity.

2. After the appearance of LED lights in 2:BBA, other big automobile manufacturers are also using LED lights as gimmicks.

3.LED is affordable, quick to start and easy to install. (Many car owners can install it after they buy it themselves, so they don't need to go to a refit shop to avoid being slaughtered. )

Domestic LED recommends Han Lei new LED lamp.

Suggestions on refitting car lights

1: If the lamp is equipped with led, I also suggest installing LED.

2.2: The effect of LED lens is still very good.

3. if you are hesitant about LED or xenon lamp, first xenon lamp.

4. At present, the best modification scheme on the market is xenon lamp lens.

As far as the current headlights are concerned, if the modified lenses are definitely xenon lamps, LED dual lenses have no advantage in brightness for the time being, and their stability is not as good as xenon lamps! If you just change the light bulb, it must be an LED light bulb. Why is this? Because the LED bulb is a single piece and the LED is a component, structurally speaking. More stable! Moreover, LEDs have the advantages of long life and energy saving, that is, they are on when they are on.

Please add lenses when changing the lights.

Xenon lamp technology is relatively mature, xenon lamp and LED must be equipped with lenses, otherwise it is illegally modified.
