IP is the international code used to identify the protection level IP level consists of two numbers, the first number represents dust prevention; the second number represents waterproof, and the larger the number is, the better the protection group leader is.

Dustproof grade

Definition of number protection degree

0 no protection no special protection

1. Prevent the intrusion of objects larger than 50 mm, and prevent the intrusion of objects larger than 50 mm in diameter due to the inadvertent contact with the internal parts of the lamp

2. Prevent the intrusion of objects larger than 12mm, and prevent the fingers from touching the internal parts of the lamp

3. Prevent the full invasion of objects larger than 2.5mm, and prevent the invasion of tools, wires or objects larger than 2.5mm in diameter

4. Prevent the invasion of objects larger than 1.0mm, and prevent the invasion of mosquitoes, flies, insects or objects larger than 1.0 in diameter

5. Dust prevention cannot completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the electrical system

6. Dust prevention completely prevents dust intrusion

Waterproof grade

Definition of number protection degree

0 no protection no special protection

1. Prevent water drop from invading and vertical dropping

2. When the lamp is inclined for 15 degrees, water dripping is still prevented. When the lamp is inclined for 15 degrees, water dripping is still prevented

3. Prevent the injected water from intruding into the rainwater, or the water sprayed in the direction of the vertical angle less than 50 degrees

4. Prevent splashing water from invading and prevent splashing water from all directions from invading

5. Prevent the water of big waves from intruding. Prevent the water of big waves or spray holes from intruding

6. Prevent the water of big waves from intruding into the water of lamps and lanterns, and ensure the normal operation of lamps and lanterns under certain time or water pressure conditions

7. Prevent water intrusion into the lamp from sinking indefinitely under certain water pressure, and ensure the normal operation of the lamp
