Drafting of proper nouns, used for classification of dustproof, foreign invasion, the characteristics of waterproof and moistureproof.
We usually see IP * * on the lamps and lanterns and power is what we call protection level, such as IP45, IP65, IP68.
Everyone has seen it, but the IP45, IP65, IP68, what they mean?
What kind of protection level it belongs to?
The following logo circle of small make up to tell you: IP protection level is composed of two number 1.
The first number indicates the degree of dust and to prevent foreign matter from entering the product;

The greater the number, the higher the level of protection.
The meaning of the first number: 0 means no protection, no special protection of the people or things outside.
