Lamps and lanterns protection grade

Lighting protection level The lighting protection level system is drafted by the IEC (International Electro Technical Commission). The 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., must not touch the live parts of the lamp to avoid electric shock. The IP protection level of lighting fixtures is composed of two numbers. The first number indicates the level of dustproof and foreign object intrusion of the lamp; the second number indicates the degree of airtightness of the lamp against moisture and water intrusion. The larger the number, the higher the protection level. The protection levels indicated by the two marked numbers are shown in Table 1 and Table 2. The degree of protection indicated by the first marked feature number (number). The first marked number of lighting fixtures: 0 No protection, no special protection for people or things outside. IP0_ 1 Prevent the intrusion of solid objects larger than 50mm, and prevent the human body (such as the palm) from accidentally contacting the internal parts of the lamp. Prevent the intrusion of foreign objects of larger size (diameter greater than 50mm). IP1_ 2 Prevent the intrusion of solid objects larger than 12mm, and prevent human fingers from touching the internal parts of the lamp. Prevent foreign objects of medium size (diameter greater than 12mm, length greater than 80mm) from intruding. IP2_ 3 Prevent the intrusion of solid objects larger than 2.5mm, prevent tools, wires or similar small foreign objects with a diameter or thickness larger than 2.5mm from intruding into the interior of the lamp. IP3_ 4 Prevent intrusion of solid objects larger than 1.0mm to prevent the diameter Or tools, wires or similar small foreign objects with a thickness greater than 1.0mm invade and touch the internal parts of the lamp. IP4_ 5 dust-proof, completely prevent foreign objects from intruding. Although it cannot completely prevent the intrusion of dust, the amount of intrusive dust will not affect the normal operation of the lamp. IP5_ 6 is dust-tight, completely preventing the intrusion of foreign objects, and can completely prevent the intrusion of dust. IP6_ The degree of protection indicated by the second marking feature number (number) of the lighting fixture. The second marking number: 0 No protection, no special protection against people or objects outside. 1 Prevent dripping water intrusion, vertical dripping water (such as condensed water) ) Will not cause harmful effects on the lamps IP_1 2 When tilted, it can still prevent dripping intrusion. When the lamps are tilted from vertical to 15 degrees, the dripping water will not cause harmful effects on the lamps. IP_2 3 Prevent the intrusion of sprayed water, rain or rain The water sprayed in the direction with a vertical angle of less than 60 degrees enters the luminaire and causes damage. IP_3 4 Prevent splashing water intrusion, prevent splashing water from all directions from entering the luminaire and cause damage IP_4 5 Prevent spray water intrusion, prevent from all directions The water sprayed from the nozzle enters the lamp and causes damage. IP-5 6 Prevent the intrusion of large waves. The lamps installed on the deck can prevent damage caused by immersion due to the invasion of large waves. IP-6 7 Prevent water intrusion during immersion. The lamps are immersed in water. A certain time or water pressure below a certain standard can ensure that there is no damage due to water ingress. IP-7 8 prevents water intrusion during sinking. The lamp can be sunk indefinitely under the specified water pressure to ensure that there is no water ingress. And cause damage to IP-8
