Huang Guang has the ability to penetrate smog? Interpretation of LED street light application misunderstanding

There are rumors that "when the color temperature of the LED street lamp is adjusted to 3000K in the foggy weather, it can penetrate the fog." When Xiaobian saw this news, he couldn't help but wonder. When the color temperature was adjusted to 3000K in the foggy weather, he could penetrate the smog and hit the light directly to the ground. Is that true? If it is only yellow light, it can penetrate the haze, which is too far-fetched. If the light has the ability to penetrate the smog, we have to start with the principle that the smog can shield the light. This will help the light we manufacture to have the ability to penetrate the smog.

Smog is a mixture of fog and cockroaches. Fog is an aerosol system consisting of a large number of tiny water droplets or ice crystals suspended in the near-surface air, and the crucible is composed of tiny solid particles. The combination of fog and sputum leads to a sharp deterioration of visibility. This has a very serious impact on the illumination of visible light. It even has serious effects on the visible and invisible light of the military, especially military reconnaissance, and the effect is also very poor. What kind of ghost is that aerosol? I am not here to say what it is. Anyway, we remember a concept, that is, aerosol materials have two functions: absorption and scattering of light. Then, when it comes to "霾", what is this thing? We can think that this "霾" is really a ghost! It is formed by the aerosol contaminated with all the impurities that nature can contaminate.

The content of impurities in nature is too big to say, but then, if the aerosol contains natural clean impurities, although it still has a shielding effect on light, at least the person who breathes the fog with nature is harmless. However, after people smoked the smog, there was a feeling of refreshment.

In the industrialized hazy world, this is not a good thing! The harm to the human body and the pollution of the environment are very clear to everyone, skip it. So, how big is the impact on light? Without the formula to give an accurate and scientific answer, I can only say that the source of impurities in the enamel contained in the fog due to environmental damage and environmental degradation is very complicated and huge! There are three kinds of impurities such as smoke, dust and floating objects. The subdivisions in these kinds of impurities are also very complicated! For example, "dust", including: metal, mineral powder, stone powder, chemical powder... these impurities will not only harm people. The respiratory tract is also the "accomplice" of the absorption of light by aerosols.

So, now it’s time to talk about how this damn fog affects light. What is its principle? Aerosols, which show dense crystals, have a barrier to light when light passes through countless crystals. This damn aerosol crystal also absorbs light, and the scattering properties of the aerosol also weaken the penetration of light. (I just said that the two functional characteristics of the aerosol) If you have a big truck to experience or ride a tall and big car, Mercedes-Benz is in the foggy night, and the large car you are riding on the LED has been replaced. On the road of the street lamp, on the fast lane, because your car is tall, you will see that the street lamp is the most slanted line with no "infrared" or "ultraviolet" illumination angle.

The slashes form a slope, and you can't see the road at all. (Additionally, when the road lighting is a road lighting with two-way lighting on both sides), then the "green, environmentally friendly" that our LEDs advertise means Those characteristics? There is no "infrared light" or "ultraviolet light" (this was described at the time, but the current "green, environmentally friendly" requirements for LEDs are much more!) It is said that there is no infrared light, but I am I agree, because, 14 LED street lights made by most manufacturers before, the lack of red light, do not believe you can secretly ask your company's technical staff, you can also ask the chip production or packaging of the big gamma. It is precisely that infrared light and ultraviolet light have a certain penetrating ability in smog weather. Your LED meets the practical application with the concept of “green, environmental protection”. Why do you say that it is more penetrating than the conventional street lamp? Sex?

As far as the current LED street lamps are concerned, it is not impossible to have a certain ability to penetrate the smog. To achieve the mouth and the product, the reality of the price subversion can be achieved. That is to say, the LED street lamp needs to have a certain smog penetration force, improve color rendering and light saturation, and give a certain comfort to the smog weather. The value of R9 cannot be ignored. And more importantly, if you want the light to break through the smog, you must have the infrared light and ultraviolet light. These lights are the weapon to overcome the smog.

LED street lights, already have the setting of the illumination angle, most of them are projected on the road surface. Moreover, isn't there a color temperature variable application concept? Then, the light can't be changed? Affirmative! For example, the weather is normal without fog. Light and foggy weather enable infrared and ultraviolet light to assist with illumination.
