IP is the code used by the international to determine the degree of protection. The IP level consists of two numbers. The first number indicates dust protection. The second number indicates waterproof. The higher number, the better the protection level.

Dust level

Number protection degree definition

0 no protection, no special protection

1 Prevent the intrusion of objects larger than 50mm to prevent the human body from invading the internal parts of the lamp to prevent the intrusion of objects larger than 50mm in diameter.

2 Prevent objects larger than 12mm from intruding to prevent fingers from hitting internal parts of the lamp

3 Prevent all objects larger than 2.5mm from intruding to prevent intrusion of tools, wires or objects with a diameter greater than 2.5mm.

4 Prevent the intrusion of objects larger than 1.0mm to prevent the invasion of mosquitoes, insects or objects with a diameter greater than 1.0.

5 dustproof can not completely prevent dust intrusion, but the amount of intrusion will not affect the normal operation of the electrical.

waterproof level

Number protection degree definition

0 no protection, no special protection.

1 Prevent dripping water from entering the vertical drop.

2 When the angle is 15 degrees, the drip intrusion is still prevented. When the lamp is tilted by 15 degrees, the drip can still be prevented.

3 Prevent the intrusion of sprayed water to prevent rainwater, or water injected vertically with an angle of less than 50 degrees.

4 Prevent splashing water from intruding to prevent water intrusion from splashing in all directions.

5 Prevent large waves of water from intruding to prevent large waves or water jets from jetting water jets.

6 Preventing large waves of water from entering the luminaire. Invading the water can ensure the normal operation of the luminaire under certain conditions or water pressure.

7 to prevent intrusion of water into the lamps, indefinitely in the sinking water under certain water pressure conditions, and to ensure the normal operation of the lamps.

8 to prevent the impact of sinking.
