First of all, let’s take a look at why there is fog and how it is formed?
When people take a bath, the temperature of the shower water is roughly the same as the body temperature, between 35°C and 40°C. However,the surface temperature of the bathroom mirror is slightly lower than room temperature. Because the room temperature is lower in winter, the temperature difference between the bathroom mirror and the air is greater, so the fog formed is thicker, and it takes longer to dissipate naturally. That’s why we need LED Anti-fog mirrors.
Secondly, why do we need to defogging
Just imagine, when you are ready to comb your hair in the mirror after taking a shower, you find that the mirror is foggy and you can’t see anything. Is it very depressed ? Let alone putting on makeup in the mirror.
Then the mirror should not only be anti-fog, but also meet the needs of makeup most of the time. Most of the lights in the mirror cabinets on the market are used for decoration, and cannot meet the needs of makeup. Either the lighting position is not good or the brightness is insufficient. At that time, the advantages of the LED bathroom smart mirror were revealed~
Finally, how to defogging?
First of all. Let us look at the reasons for the fogging of bathroom mirrors, then we can analyze how to prevent fogging:
First principle: Reduce the humidity of the air.
Second principle: Reduce the temperature difference between water vapor and bathroom mirror (increase the surface temperature of bathroom mirror).
Third Principle : Let the fog fail to form on the surface of the bathroom mirror.
The first is a coated anti-fog lens.
It consists of coating micropores to prevent fogging layers..Conductive material ATO and silicon oxide made of anti-fog coating, which can form a good hydrophilic effect. In addition, anti-bacterial agents that can avoid static electricity have many effects such as anti-fog, anti-pollution and avoiding static electricity;
Through the formation of the mist layer of the microporous structure of the coating, it theoretically has the effects of anti-fog, anti-fouling and anti-static, but most of these coatings can last for a short time
The second type is electric heating anti-fog lens.
This type of lens is heated by electric heating to make the humidity of the mirror surface higher, so that the fog layer can not be formed naturally, and the fog can be rapidly increased.
The most effective method to eliminate fog is to heat the mirror itself by electricity to reduce the temperature difference. Most LED anti-fog mirrors on the market use this method. When there is no fog, the mirror surface can be heated to prevent fog. And when it is foggy, the heating can remove the fog. The time except the fog is related to the heating power. However, it should be noted that if the heating power is too large and the temperature changes too fast, problems may occur. such as cracking of the mirror.
The third type is the nano-composite anti-fog lens.
which uses the separation of chemical and physical principles. Then let it stick firmly to the glass. So that there is no way to form water drops, and naturally they can reach you. The anti-fog effect you want.
