The lamp is classfied based on the prevent intrusion of foreign matter,dust , waterproof, anti-moisture. Foreign matter refers to live parts within the lamp tools and human finger can not touch to avoid electric shock.

 

IP protection class is composed by two figures, the first number indicates the dustproof ie preventing intrusion of foreign material; the second number represents the lamp against moisture, water invasion. The larger the number, the better the lamp, the two figures marked protection level represents indicating degree of protection are shown bellow.

 

The first one number marked characteristic refers to the degree of protection


0 no protection no special protection against the outside   IP0-

1 prevent the intrusion of solid objects greater than 50mm and the human (eg palm) accidentally touching the inside of the LED lamp parts. Prevent foreign objects with larger size (diameter greater than 50mm) intrusion  IP1-


2 prevent the intrusion of solid objects greater than 12mm and a human being¡¯s finger touching the inside of the LED lamp parts. Prevent the foreign objects with medium size (diameter greater than 12mm, a length greater than 80mm) intrusion  IP2-


3 prevent the intrusion of solid objects greater than 2.5mm or tools, wires or foreign objects in diameter and thickness greater than2.5mm prevention and contacting with the LED light and internal parts IP3-


4 prevent the intrusion of solid objects greater than 1.0mm or tools, wires or foreign objects in diameter and thickness greater than 1.0mm prevention and contacting with the LED light and internal parts IP4-


5 completely prevent intrusion of foreign objects. the amount of intrusion of dust will not affect the normal operation of the lamp despite it can not completely prevent dust intrusion  IP5-


6 completely prevent intrusion of foreign objects, and can completely prevent dust intrusion IP6-

 

The second numbers (digital) marked within the meaning of the degree of protection

0 No protection against the outside or things, that is no special protection  IP-0


1 prevent the intrusion of drip,that is the vertical drip (eg condensation water) will not cause harmful effects on the LED lamps  IP-1


2 prevent drip invading when the LED lamps incline at 15 ¡ã tilted from vertical, the water dripping on the LED lamps will not cause harmful effects IP-2


3 prevent the intrusion of water sprayed that is rainproof or protect the LED lights from being damaged by water sprayed at less than 60 ¡ãangle between vertical angle  IP-3


4 prevent splashing water splashing that is preventing the intrusion of water from all directions into the LED lights  IP-


5 prevent the injected water that is preventing the intrusion of water from all directions out from the nozzle into the LED lights P-5


6 prevent the intrusion of waves that is preventing the big waves and flooding invasion of the LED lamps installed in on deck  the IP-6


7 prevent water from entering the LED lamps immersed in water there is no damage to lamp when being immersed at a certain time or in a certain standard water pressure  IP-7


8 prevent water from ingress of LED light sunk  IP-8
