How to distinguish the protection level of the LED explosion lamp?

             We often see the words "protection grade IP65" on the electrical equipment such as LED explosion lamp and some outdoor lighting equipment or on the nameplate. What do these numbers and letters mean and how to distinguish them?

              IP** is the degree of protection, IP is the international level symbol (INTERNATIONAL PROTECTION RATINGS), followed by two digits, the first digit indicates the dust-proof capability of the device, called the first feature number, and the second digit indicates the device"s Water resistance, called the second feature number. The first characteristic number has a value of 1 to prevent solids larger than 50 mm in diameter from entering the body (eg, accidental contact with the hand); 2 means to prevent solids larger than 12.5 mm in diameter from entering the body (eg, fingers); Prevent solids larger than 2.5mm in diameter from entering the body (eg tools, wires); 4 means prevent solids larger than 1mm in diameter from entering the body (eg gadgets, wires); 5- represents dust, dust can not reach The extent to which protective equipment is functioning properly; 6- represents dust-free entry. The second characteristic number has 1 means that there is no harmful influence on vertical dripping; 2 means that when the outer casing is from normal 15, the vertical dripping has no harmful effect; 3 - the vertical watering within the range of 60 has no harmful effect; Represents splashing water in any direction without harmful effects; 5- means no water in any direction has no harmful effects; 6- stands for anti-wave; 7- stands for anti-soaking effect; 8- stands for anti-submersible effect.

               It can be seen from the above that the electrical equipment such as LED explosion lamp should achieve a waterproof rating of at least IP65.
