Windage noise caused by auxiliary lights
The choice of shape and installation position of the auxiliary light are very important; otherwise, it is easy to generate a lot of noise, especially when it is installed on the roof. It may also cause roof resonance, which will have a direct negative impact on driving safety.
If the auxiliary light is installed at the front of the car, then you also need to consider the impact of the auxiliary light on the internal structure of the vehicle cabin, such as a turbocharged intercooler (whether it is gasoline or diesel, the probability of supercharging is much greater than that of non-supercharging ), the heat dissipation effect of water tanks, air-conditioning condensing plates, etc.; and the importance of the normal operation of these devices is self-evident, so the installation of auxiliary lights is a problem that needs to be carefully considered.
There is another problem that needs to be paid attention to when installing auxiliary lights on the top, that is, the height setting; because now the garages and height limit poles in many places are 2.2 meters or even 2 meters, and the off-road vehicles themselves are very tall, and many people have to carry out Therefore, after installing the auxiliary light at the roof position, it is easy to be super high; this will cause a lot of trouble in daily use, and even many people cannot even enter their own underground parking spaces Go, this is embarrassing.
Another thing to pay attention to when installing the auxiliary light on the top is that the position should not be too far forward, otherwise it will easily cause reflections on the hood when the light is turned on, which will make the eyes uncomfortable.
Misunderstandings of fog lights:
Many people try to make the brightness of the fog lights higher when refitting the fog lights, but it may be a question of how bright they are; most people will install lights with low color temperature when refitting the fog lights. For example, the golden eye was very popular in the past few years; but have you noticed that the original fog lamps have changed from yellow to white many years ago. Why is this, doesn’t the factory understand the power of Golden Eye?
The key to the problem is that the function of the fog lamp is passive. Its function is to be discovered by the other party. It depends on the width and density of the light to increase the probability of being discovered, rather than using its own brightness to illuminate the road; because water Fog itself is actually composed of extremely small water droplets, and water itself is a strong reflector of light.
The characteristics of water mist are small size and high density. In addition to reflecting light, it can also refract, diffract and transmit light. In this way, combined with its high-density characteristics, it becomes a combination of countless strong reflective points; The higher the illumination intensity of the fog lights, the stronger the reflection effect of the water mist, which is why we turn on the headlights in foggy days as if shining on an invisible wall, and the sight is worse than the real wall, because the fog It has a mask reflection effect.
In this case, no matter how low the color temperature of your fog lights is, it is useless even if they can penetrate the water mist and shine on the road, because your sight is blocked by the water mist, and your golden eyes are at best the color of the fog. Dye yellow, and then the other party finds a piece of yellow glowing moving in a white mist-that is you.
But when the fog is heavy, whether it is yellow, red or other colors, its visible distance is very limited. At the relative speed (36km/h+36km/h, it is probably the limit speed of human running, for cars It’s already very slow for a person) When it’s easy to exceed 70 kilometers, this distance is not much different from nothing.
The only way to see the road clearly in heavy fog is to turn off all the headlights. It is easier to see clearly by using the weak light of the width indicator to illuminate the reflective tape on the road. We once had the experience of driving in Hebei when encountering heavy fog at night and turning off all the headlights to look at the treetops on the side of the road.
Problems and solutions caused by auxiliary lights: illegal modification
When installing auxiliary lights, you must pay attention to the legalization of modification; although modifying the product itself and using the modified product are two different things; for example, I installed some products but did not use them. As a commodity, a lamp can exist legally, and my purchase of it is also a legal transaction.
In theory, only when the auxiliary light is used improperly can it constitute an illegal act due to improper behavior, such as turning it on in an urban street, which seriously affects the other party’s sight and leads to driving safety, then this behavior constitutes an illegal act; but if I Use it in no-man’s land, because it does not hinder the safety of public roads, then this is a reasonable and legal use.
Of course, if the position of the lights you install (or change the appearance of the vehicle) does not meet the requirements of the regulations, it is also an illegal act, and you can also be brought to justice without using the lights illegally.
But the problem is that in most cases, some local law enforcement agencies don’t distinguish so carefully with you, and the auxiliary lights are something that the police don’t like to see, so the so-called “illegal modification” will actually bring us a lot of trouble. Anxiety is often not limited to the loss of personal property, and sometimes it is more important to affect the mood of travel; therefore, when installing auxiliary lamp products, we must pay attention to rationalization, and try to avoid troubles caused by them when traveling.
Some little knowledge about auxiliary lights:
Lux lux, legal symbol lx) is the unit of illumination (Illuminance). When the luminous flux obtained by an object uniformly illuminated by light is 1 lumen on an area of 1 square meter, its illuminance is 1 lux. The illumination suitable for reading and sewing is about 500 lux
Common size classification of auxiliary lights:
Round or square rectangle: all expressed in inches, 1 inch, 3 inches, 5 inches, 6 inches, 7 inches, 9 inches, etc.;
Light source: halogen, xenon, LED, laser, although halogen has been around for a long time, it is still widely used because of its cheap price, convenient replacement and low cost;
Advantages of halogen lamps:
-
The price is cheap, the luminous body is light in weight, no additional starting equipment is required, the replacement method is simple, and it can be carried in large quantities for backup;
-
The lumen is significantly lower than other advanced light sources, the service life is short, and the brightness will decrease at the end of the life;
Advantages of Xenon:
The price is gradually reduced, the service life is long, the brightness is high, the power consumption is low, and the color temperature range can be selected;
Additional starting equipment is required, the price is more expensive than halogen, and it is troublesome to replace the illuminant;
Advantages of LEDs
The characteristics of LED are basically the same as that of xenon, but it is more compact, so the installation method and appearance will make its arrangement and installation more convenient; its life is longer, and there is no problem of delay in starting of xenon.
LED strip auxiliary light
The advantage of LED is that it can be made into any length to accommodate more LED illuminants. It has higher brightness and can design a reflective bowl that takes into account the range and width at the same time; the disadvantage is that the power consumption is relatively large, and the heat generated by the entire strip light It is also large and requires a large area of heat sink for auxiliary heat dissipation.
Those who plant less harvest less, and those who grow more harvest more.
