Misunderstanding of fog lamp:
When many people modify fog lamps, they strive to make the brightness of fog lamps higher, but to what extent may be an unclear problem; when most people retrofit fog lamps, they install low-temperature lamps, such as Goldeneye, which was very hot a few years ago. But have you found the original factory fog lights numerous years ago from yellow to white? Why? Doesn't the factory understand the power of Goldeneye?
The key to the problem is that fog lamps are passive, and their role is to be found by the other side. It is to increase the probability of being found by the width and density of the light irradiation, rather than to illuminate the road with their own brightness. Because the spray itself is actually made up of tiny water droplets, water itself is a strong reflector of light.
Water mist is characterized by short volume and high density. In addition to reflecting light, it can also be refracted, diffracted and penetrated. In this way, combined with its high density characteristics, it becomes a combination of numerous strong reflecting points. The higher the intensity of fog lamps, the stronger the reflection effect of water fog, which is why when we turn on the headlights on foggy days, it is like shining into an invisible wall, and it is worse than the real wall line of sight, because fog has a mask reflection effect.
In this case, it doesn't matter how low the temperature of your fog lamp is, and it doesn't matter if it shines through the mist and onto the road, because your view is blocked by the mist, and the best your golden eye can do is dye the mist yellow, and then the other person finds a yellow moving in the middle of the white fog -- that's you.
But on foggy days, whether yellow, red or any other color, it can be seen with a very limited range, which is not much different when the relative speed (at 36km/h+36km/h, which is about the limit of human running speed and is already extremely moderate for cars) easily exceeds 70 km/h.
The only way to see the road in heavy fog is to turn off all the headlights. It is easier to see the reflective belt of the road with the faint light of a wide indicator lamp. We once had the experience of driving in Hebei Province when we encountered heavy fog at night and turned off all the headlights to look at the treetops by the roadside.
Auxiliary lamp problems and solutions: illegal modification
When installing auxiliary lights, we must pay attention to the legalization of refit; although modifying the product itself and using it are two different things; for example, I installed some products but did not use them. In fact, this is simply a problem with my private property placement. As a kind of commodity, auxiliary lamps can exist legally, and my purchase of them is also a legal transaction.
In theory, only when the auxiliary light is improperly used, it may be illegal because of improper behavior. For example, when the street is opened in the urban area, it gravely affects the line of sight of the other party and leads to driving safety, then this behavior constitutes an illegal; but if I use it in a no-man's land because it doesn't interfere with the safety of a public road, then it's a reasonable and legal use.
Of course, if you install lights (or alter the appearance of the vehicle) that do not meet the requirements of the regulations, it is also an illegal act, and you can be prosecuted for not using the illegal lighting premise.
But the problem is that in most cases some local law enforcement agencies do not distinguish with you so detailed, and auxiliary lights are particularly unpopular with the police, so the so-called "illegal modification" will indeed bring us a lot of trouble. These troubles numerous times are not limited to personal property losses. Sometimes travel mood affected is more vital; so in the installation of auxiliary lamp products, we must pay attention to rationalization, as far as possible to avoid trouble when traveling because of them.
A few things about auxiliary lights:
lux (legal symbol lx) is a unit of Illuminance. When the luminous flux of an object uniformly illuminated by light is 1 lumen over an area of 1 square meter, its illumination is 1 lux. The illumination suitable for reading and sewing etc. is about 500 lux
Common size classification of auxiliary lamps:
Round or square rectangle: all 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 extremely lengthy, but because the price is reasonable, convenient replacement cost is low, so it is still used in large quantities;
advantages of halogen lamps:
Low price, light weight of luminous body, no need for additional starting equipment, simple replacement method, can carry a large number of spare;
the luminance is obviously lower than other advanced light sources, the service life is short, the brightness will be reduced in the late life;
advantages of xenon:
Gradually reduced price, long service life, high brightness, low power consumption, wide range of optional color temperatures;
additional starting equipment is needed, the price is expensive compared with halogen, and the replacement of luminous body is troublesome;
advantages of LED
Leds have much the same characteristics as xenon, but are smaller, so installation methods and styling make them easier to arrange and install; it also has a longer life and does not have the xenon startup delay of lighting problems.
LED strip auxiliary light
The advantage of LED is that it can be made to any length to accommodate additional LED luminous body, its higher brightness, can be designed at the same time to take into account the range and width of the reflective bowl; the disadvantage is that the power consumption is relatively large, and the heat of the whole lamp is also large, so a large area of heat sink is needed for auxiliary heat dissipation.
Points for Attention on lighting modification of off-road Vehicle (Part 2)
Wind resistance noise caused by auxiliary lights
The selection and installation position of auxiliary lamp shape and ws2815 led strip are extremely critical; otherwise, it is easy to produce a lot of noise, especially when it is installed on the roof of the car. If it is equipped with unreasonable light frame - luggage rack, then in addition to causing huge noise, it may cause roof resonance, which will directly bring negative impact on driving safety.
If the auxiliary light is installed in the position of the head, then you also have to consider the influence of the auxiliary light on the internal structure of the vehicle cabin, such as the turbocharged intercooler (whether it is gasoline or diesel, the probability of pressurization has been considerably more than the non-pressurized), the cooling effect of the water tank, air conditioning condensation plate and so on; the importance of the normal operation of these equipment is self-evident, so the installation of auxiliary lights is a problem that needs to be critically considered.
There is another problem to pay attention to in the installation of auxiliary lights on the top, that is, the setting of height; because now numerous places in the garage, the height limit bar is 2.2 meters or even 2 meters, and the off-road vehicle itself is extremely steep, coupled with a lot of people who have raised and modified the huge tire, thus in the installation of the roof position of the auxiliary light, it is easy to be elevated; this will bring a lot of trouble to daily use, even numerous people can't even get into their own underground parking space, which is extremely embarrassing.
There is also one point to pay attention to the installation of auxiliary lights on the top, that is, the position is not too much forward, otherwise the light is easily cause the hood reflection, will make the eyes extremely uncomfortable.
