IP is a protection level, with the first being dust and the second being waterproof.
Dust level
No. Protection level Definition 0 No protection No special protection 1 Prevent objects larger than 50mm from intruding. Prevent humans from inadvertently hitting internal parts of the lamp. Prevent intrusion of objects larger than 50mm. 2 Prevent entry of objects larger than 12mm. Preventing intrusion of objects larger than 2.5 mm to prevent tools with diameters greater than 2.5 mm, intrusion of wires or objects 4 Intrusion of objects larger than 1.0 mm Prevent ingress of mosquitoes, flies, insects or objects with a diameter greater than 1.0 5 Dust prevention does not completely prevent dust from intruding, but the amount of dust intrusion does not affect the normal operation of the lamp 6 dust completely prevent the intrusion of dust and waterproof rating <br> <br>
No. Protection level Definition 0 No protection No special protection 1 Prevention of drip intrusion Prevention of vertical drop of water 2 Prevention of drip ingression at inclination of 15 degrees When the lamp is tilted by 15 degrees, it can still be prevented from dripping 3 Prevent jetted water from intruding to prevent rain, or Water that is sprayed in a direction with an angle less than 50 degrees perpendicular to the angle of entry Prevents splashing water from intruding Water ingress from each direction is prevented 5 Water intrusion from large waves is prevented Water intrusion from large waves or water spray holes is prevented 6 Water from large waves is prevented Invade the lamp and invade the water. In a certain time or water pressure conditions, it can still ensure the normal operation of the lamp. 7 Prevent the intrusion of water into the lamp. Indefinite submerged water under certain water pressure conditions and ensure the normal operation of the lamp. 8 Prevent sunk. The impact of this reminds me of a problem where the relationship between IPX6 and IPX7 is parallel, with a different focus. For example, IP67 devices may not be able to pass the IP66 test. In other cases, the larger the number, the better the protection level. Explosion-proof environment generally requires IP65 or more. Now most domestic manufacturers' equipment is IP65, and a few imported brands can partially achieve IP66.
