Can solar street light penetrate smog?

by:Litel Technology     2022-05-24
Smog is a mixture of fog and haze. Fog is a fragment of aerosol composed of small numbers of giant water droplets or ice crystals suspended in the air near the air, while haze is composed of large solid particles. The combined effect of fog and haze leads to a sharp improvement in visibility, which has a very serious impact on the illumination of visible light, and even has a serious impact on military visible and invisible light, especially military reconnaissance, the effect has also become very poor. What the hell is aerosol? I won't say what it is here, anyway, we have to remember a concept, that is, aerosol substances have two functions: they can absorb and scatter light. So, when it comes to 'hazeThe content of nature's impurities is too large to tell, but then again, if the aerosol contains nature's clean impurities, although it still has a shielding effect on light, at least people breathing the haze formed by nature's fog is harmful. On the contrary, it makes people feel refreshed after inhaling the smog. In the industrialized world of smog, this smog is not a bad thing! Everyone knows the harm to the human body and the purification of the environment, so I won't talk about it. So, how big is the impact on light? There is no calculation formula to give an accurate and superstitious answer. I can only say that the source of impurities in the haze caused by environmental damage and environmental improvement contained in fog is very complex and huge! There are three types of impurities such as smoke, dust, and floating objects. The subdivision of these types of impurities is also very complicated! For example, 'dust' includes: metal, mineral powder, stone powder, chemical powder... These impurities are not only harmful to people The respiratory tract is also the 'minion' of aerosol's absorption of light. So, now it’s time to talk about how this damn fog affects light? What’s the principle? Aerosols, which show a dense layer of crystals, when light passes through a number of crystals, in addition to having a blocking effect on light , the damn aerosol crystal will also absorb light, and the scattering properties of the aerosol also weaken the penetration of light. (I just mentioned the two functional properties of aerosols) If you have the experience of driving a large truck or riding a tall and large car, you are running in a foggy night, and the large car you are riding in is driving in a changed solar On the road with street light, in the slow lane, because your car is short, you will see that the most irritating street light is the oblique line without 'infrared light' and 'ultraviolet light'. The oblique line forms an inclined plane, and you can hardly see the road condition (additionally, when the road lighting is the road lighting condition with two-way lights on both sides) After all, the 'green and environmental protection' advertised by our LED refers to the Those characteristics? It refers to the absence of 'infrared light' and 'ultraviolet light' (it was described in this way in advance, but there are many requirements for the 'green and environmental protection' of LEDs!) It is said that there is no infrared light. I agree, because most of the solar street lights manufactured by most consumer manufacturers in the past are lacking in red light. If you don’t believe me, you can secretly ask your company’s technicians, or you can ask Dajia who does chip production or packaging. Precisely, infrared light and ultraviolet light have certain penetrating ability in haze weather. Your LED meets the ideal use with the concept of 'green and environmental protection'. How can you say that it is more penetrating to haze than conventional street lights Sexuality? As far as the current solar street light is concerned, it is not impossible to have a certain ability to penetrate smog. To achieve the same quality, you must bypass the ideal of price overturning. That is to say, the solar street light must have a certain degree of haze penetration, improve color rendering and light saturation, and give people a certain sense of comfort under the condition of haze weather. The value of R9 cannot be ignored. There is a more important point, in order for the light to break through the haze, it must have fierce infrared light and ultraviolet light. These lights are the sharp weapons to restrain the haze. Solar street light used to have the setting of the light-emitting angle, and most of it was projected on the road. Besides, isn't there a concept of use with variable color temperature now? So, can the light be variable? Sure! For example, the weather without fog is normal LED light, enabling infrared light and ultraviolet light to help illuminate in foggy weather.
