LED lamp IP protection level meaning

The LED application should pay attention to the specifications such as moisture prevention and pouring. The IP (INTERNATIONAL PROTECTION) protection level system is drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION). 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 is composed of two digits. The first digit indicates the level of the lamp from dust and foreign objects. The second digit indicates the degree of airtightness of the lamp against moisture and water intrusion. The higher the number, the higher the degree of protection,higher.

The first indicator number is defined:


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 accidentally coming into contact with the parts inside the lamp. 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.


3 Prevent the intrusion of solid objects larger than 2.5mm: Prevent the intrusion of tools, wires or similar small objects with a diameter or thickness greater than 2.5mm into contact with the parts inside the lamp.


4 Prevent the intrusion of solid objects larger than 1.0mm: Prevent the intrusion of tools, wires or similar small objects with a diameter or thickness greater than 1.0mm into contact with the parts inside the lamp.


5 Dustproof: completely prevent foreign matter 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.


6 Dustproof: completely prevent foreign objects from entering, and can completely prevent dust from entering


The second indicator number is defined:


0 no protection: no protection


1 Prevent dripping ingress: Water droplets dripping vertically (such as condensate) will not cause harmful effects on the lamp.


2 It can prevent dripping intrusion when tilted at 15 degrees: when the luminaire is tilted vertically to 15 degrees, dripping water will not cause harmful effects on the luminaire


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 luminaire.


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 is not damaged by water ingress.


8 Preventing the intrusion of water when it is sunk: The indefinite sinking of the luminaire ensures that it is not damaged by the influent water under the specified water pressure.
