In order to prevent dust, solid foreign matter and water from entering the lamp cavity, touching or accumulating on live parts, causing flashover, short circuit or damage to electrical insulation, there are a variety of enclosure protection methods to protect electrical insulation (purely personal Protective measures such as safety fences installed on the outside of the enclosure are not counted as part of the enclosure). This article does not include the degree of protection related to mechanical damage, explosive, corrosive gas, mold, and insect pests. Let’s learn more about the standard classification of LED lamp housing protection grades!

Use the characteristic letter "IP" followed by two numbers to characterize the enclosure protection level. The IP (International Protection) protection level system was drafted by the IEC (International Electro Technical Commission). The LED lamps are classified according to their dustproof, foreign object intrusion, waterproof, and moisture-proof characteristics. The foreign objects referred to here, including tools, human fingers, etc., are not allowed to touch the live parts of the LED lamp. The first number indicates the level of dustproof and foreign object intrusion of the LED lamp, which is divided into 0-6 levels; the second number indicates the degree of airtightness of the LED lamp against moisture and water intrusion, which is divided into 0-8 levels. The larger the number, the higher the protection level.
