When purchasing LED lamps, product safety and quality are the most concerned projects, and the LED lamps market has a wide variety of products and serious homogenization, which brings certain difficulties to the selection of LED products. As long as you understand the IP level of protection level, you will know the product safety! IP (INTERNATIONAL PROTECTION) protection level system is drafted by IEC (INTERNATIONAL ELECTROTECHNI CALCOMMISSION). The luminaires are graded according to their dust and moisture resistance characteristics. The foreign objects referred to here include tools, human fingers, etc., which are not accessible to the live parts of the lamps to avoid electric shock.
The IP protection level consists of two digits:
The first number indicates the level at which the luminaire is dust-free and prevents foreign objects from entering.
The second digit indicates the degree of sealing of the lamp against moisture and water intrusion. The higher the number, the higher the degree of protection.
Classification of the prevention of foreign object invasion:
0 No protection: no special protection for people or things outside
1 Prevent the intrusion of solid objects larger than 50mm: Prevent the human body (such as the palm) from coming into contact with the parts inside the lamp due to accident. Prevent foreign objects of larger size (greater than 50mm in diameter) from intruding.
2 Prevent the intrusion of solid objects larger than 12mm: Prevent human fingers from coming into contact with parts inside the lamp to prevent intrusion of medium-sized (12mm in diameter) foreign objects.
3Intrusion of solid objects greater than 2.5 mm is prevented: tools, wires or similar details with a diameter or thickness greater than 2.5 mm are prevented from intruding into contact with parts inside the luminaire.
4Intrusion of solid objects greater than 1.0 mm is prevented: tools, wires or similar details with a diameter or thickness greater than 1.0 mm are prevented from intruding into contact with parts inside the luminaire.
5Dustproof: completely prevent foreign objects from entering. Although it can't completely prevent dust from entering, the amount of intruded dust does not affect the normal operation of the lamp.
6Dustproof: completely prevent foreign objects from entering, and can completely prevent dust from entering
Dampproof and waterproof grade division:
0 no protection: no protection.
1 Prevent drip intrusion: Vertical drops of water (such as condensate) will not cause harmful effects on the lamp.
2 When the angle is 15 degrees, the drip intrusion can still be prevented: when the lamp is tilted vertically to 15 degrees, the dripping water will not have harmful effects on the lamp.
3 Prevent the intrusion of sprayed water: prevent rain, or prevent water sprayed in a direction with a vertical angle of less than 60 degrees from entering the fixture and causing damage.
4 Prevent splashing water from invading: Prevent water from splashing in all directions from entering the fixture and causing damage.
5 Prevent intrusion of injected water: Prevent water from the nozzles from entering the lamp from entering the lamp in all directions.
6 Prevent the intrusion of large waves: Fixtures installed on the deck to prevent damage caused by large waves.
7 Prevent water intrusion when immersed in water: The lamp is immersed in water for a certain period of time or the water pressure is below a certain standard to ensure that it will not be damaged by water ingress.
8 Prevent the intrusion of water when it is sunk: The indefinite sinking of the lamp can ensure that it will not be damaged by water in the specified water pressure.
It is not difficult to see from the above, qualified
