[light] if a car headlight is called the most attractive security configuration of the car, no one should be opposed to it, and the function, design and branding in a body, all manufacturers will do in the eyes. But the most popular is the LED headlamps (laser headlights still small), it is like a strong young man is rapidly spreading his career, but has not retired in xenon headlamps to continue its business, whether some new things beyond the old products? So let's analyze today's queries about two light sources.
A paragraph review the characteristics of LED headlamps and xenon lamps:
Xenon lamp: high brightness, longer life than halogen lamp, looks better than halogen yellow light;
LED: its advantage is to add a better word on the advantages of xenon lamp, in addition to the xenon lamp, there are two absolute advantages, that is, greater tolerance of design, appearance party killer; lighting speed is extremely fast, no reaction process.
The above advantages and disadvantages are recognized light source characteristics, no more words, not to repeat the details.
Popularization of LED headlamps is inevitable
In fact, the car equipped with LED headlights is not something new, as early as 10 years ago has been equipped with mass production models, you remember what kind of car is it? Audi said the friend is only half of the first production car is equipped with LED 07 Lexus LS600h, Audi R8 is the bearer of the first full LED headlamps, popular after so many years, in the design also play too many tricks, it is also popular in one of the important factors. Can the greatest degree of reduction of the designer design concepts for the headlight styling, but also can inject more brand gene.
One of the functions of the diversity is the luminous element of individual factors, LED is very small, so in the design of tolerance than the previous source are high, also because of its high brightness so lighting needs of the most primitive has a good foundation; the number of LED light source theory without an absolute conclusion, so in the irradiated area can easily make a fuss, so no dead, dead and destroyed is clean enough, more is the design cost, but also flawed halogen and xenon lamp irradiation angle this "straight to the light source can not be solved, they have reached the structure leads to unable to break through the bottleneck.
Now the LED headlamp products in the light source layout can be described as changing the pattern of innovation. But no matter how innovation, in principle LED headlamps will light the "send out" only two kinds, one is the lens, the other is a reflective bowl, just by a common LED lamp light source, so the reflection bowl will be more complex than the traditional structure.
We look for the same model, different light source to feel
I'm looking for the two cars are Lincoln MKX, a high (full LED lens) and a low (near light xenon lamp, one lens) now put down everything we said above, return to the most basic function of irradiation, see the same models of two kinds of lighting effects.
As for why the comparison did not mention halogen headlights, one is from the product coverage of this indeed is not the mainstream, or that is not the main focus of the two users, is now very few models have LED, xenon lamp and halogen light source three, so the first comparison between the two kinds of the most mainstream.
Make sure that the light you say is true light, not white
No matter from the car or car, LED generally will be very beautiful white, more than the xenon lamp xenon lamp in white, to know the "hot" (after a few seconds the lights open in normal temperature) is actually not so white (with halogen Bibaideduo, but compared to LED feel there are some slightly yellow), so we subjectively light more from the white of the feeling, and the white light to the evaluation of a good use, is untenable; white light from the appearance looks beautiful is not sitting in the car is very bright, which is directly related to with the reflective structure design of car lights, like ordinary flashlight to you look very bright, but according to the ground when you don't feel too much help, design a good spot flashlight is not the same.
LED is the biggest advantage of the light
Brightness usually are partially influenced by external sensory perception is needed here, dressing, white, beautiful and good lighting effect is not proportional, and reflective device design and the irradiation range is the key, and this is also the LED of multi - point source advantage first day.
This picture reduction degree is no problem, the naked eye basically is like this, LED low light mode for "front light" coverage to improve more than the xenon lamp, similar to the dental hospital so shadowless lamp, LED lamp models previously tested; from the car, lights the visual feeling indeed than xenon and halogen lamp "two such high-grade".
2、What are the disadvantages?
We also get the Lincoln MKX version of the test drive for the high beam xenon lamp lights and "eye" design, the beam will be close to the axis, can effectively improve the lighting effect of straight beam, cut back to near light and separate to ensure the lighting of the lamps on both sides, the width, this function is actually moving with the additional steering action a lot of cars with xenon lamp, have similar design for light angle, respectively because only one lamp, can only use the mechanical design to solve the problem of the irradiated area.
Penetration - LED is not that perfect
From the measured data, the effect of penetration under the same conditions, the Lincoln MKX 2.0T xenon lamp than the 2.7T models of the full LED headlamps to be slightly better, the average left right far 3 meters.
Open the beam to try again, from the data reflected the results are the same, in the lane axis take 50cm high 10 LX boundary, xenon lamp LED distance 15 meters distance, penetration ability is better. I also drove a lot before the night, this point is also deep, pallid light actually sitting in the car to the front and not feel much lighter, especially in fog and rain conditions, only near light work, white light bright can not find a near distance the big white walls of the rhythm, feel very uncomfortable.
So these words actually mean is very simple, is now on the market LED headlamps common temperature is relatively high, very white, penetrating with xenon lamp is no advantage, this is also a small price looks more handsome and some of the other factors, lensless LED headlamps also affect the focusing ability insufficient (related, and design cost has been tested the two paragraph of lensless LED lamp group, Audi A8L performance is acceptable, civic achievement is not ideal, often in the city) if used, from inside and outside look very beautiful LED is not wrong, after all, look fashionable indeed the user just need to, but if often run in the night, if it is "product design lack of investment, it is likely to encounter insufficient penetration is also true. In theory, it's not a complicated thing for LED to move on color temperature. Maybe it's hard for the lighting factory to make such a balance now
to glare is to cause LED mishap
Everything is not perfect, LED have a fatal mishap, but sometimes the owners feel that only light brought to the object vehicle problems, the super light "hard" test, that night was the new BMW 5 series high shake a few times, what a cool acid...... Every time the LED beam is shaking, it is instantly closed eyes, even back, can not stand. Although the xenon lamp is also white high light, but because 90% xenon lamps are equipped with lenses, so the subjective feeling is relatively better, although it is also dazzling enough, but not have the sense of instant blindness.
In the new American IIHS light test, have similar feedback, with a lot of new models LED lights don't get the highest points are lost because of excessive glare.
If your beam is LED, don't mess with it
Friends, if your car is full LED headlamps (here, near and far is LED), then the night do not understand it, can stand on their head to 50 meters by Akira, you know, so for LED headlamps, a good automatic high beam function logic it is necessary, plus the absolute, turn lights for what is not automatic high beam.
Sum up:
A brief summary of key information:
1, LED design feel good! Good-looking！ Good-looking！ It's really nice!
2, LED is affected by the shape, number and location of the light source is small, light and uniformity is better than xenon lamp and halogen;
3, the function of more space to display, xenon lamp often need rotating lamp holder or single light source to make up for irradiation angle;
4, LED headlamps generally high color temperature, if the beam is LED, penetrating as xenon lamp and halogen awesome;
5, LED light is "hard", abuse of high beam to the car is very sad, the other side blinding yourself also has security risks;
The last chat whole, LED and xenon lamp which good this problem is not a word can be answered, judging from the inherent advantages and development potential of LED, the "young man", is better than the xenon lamp, or that is significantly more than the advantages of insufficient, so LED as would-be successors also xenon lamp is qualified; but there is not completely replace the stable effect of xenon and excellent halogen lamps, especially the need for penetrating the environment and light for damage to the vehicle. If you want to understand a light effect, the best way is to have the opportunity to test drive, observe the actual experience, to see whether the performance of light in the night under a variety of circumstances can meet their needs, that is their own needs, though the Car Buying not directly determine the factors, but see no harm.
