Interpretation of the definition of LED lighting IP protection class

From: Data:31/08/2016

LED applications should be noted that the anti moisture and dumping and other specifications, IP (PROTECTION INTERNATIONAL) protection rating system is drafted by IEC (ELECTROTECHNICAL COMMISSION INTERNATIONAL). According to the characteristic of the lamp, the lamp can prevent moisture and prevent moisture. Things here refers to the tools, the fingers are not accessible to live in part of the lamp, so as to avoid the electric shock. The IP rating is composed of two digital. The first is the number of said lamp Leechan, to prevent the intrusion of foreign objects level and a second digital said lamp moisture resistant, waterproof invasion of closeness, the greater the number said the higher the level of protection.
the first label digital definition:
0 there is no door: on the outside of the person or thing without special door
1 prevent greater than 50mm of solid objects invasion: to prevent the human body (such as the palm of the hand) due to accidents and into contact with the parts inside the lamp. To prevent the larger size (diameter greater than 50mm) the foreign matter.
2 prevent greater than 12mm solid objects invasion: to prevent the fingers come into contact with the inside the lamp parts to prevent invasion of medium size (diameter 12mm) objects.
3 prevent greater than 2.5mm solid objects invasion: prevent the diameter or thickness more than 2.5mm tools, wire, or similar details of small objects intrusion and into contact with the parts inside the lamp.
4 prevent greater than 1.0mm solid objects invasion: prevent the diameter or thickness greater than 1.0mm tools, wire, or similar details of small objects intrusion and into contact with the parts inside the lamp.
5 dust: to completely prevent the intrusion of foreign objects, although not completely prevent dust from entering, but the intrusion of dust and will not affect the lamps and lanterns of normal work.
6 dust: completely prevent intrusion of foreign objects and can completely prevent dust from entering the
the second mark digital definition:
0 there is no door: there is no door
1 to prevent water intrusion: vertical drop of the water droplets (such as condensation water) to have deleterious effects on the lights will not.
2 tilted 15 degrees still prevents water invasion: when the lamp by vertical tilt to 15 degrees, dripping on the lamp does not caused harmful effects of
3 prevent spraying of water intrusion: rain, or prevent and vertical angle less than 60 degrees in the direction of the spraying water into the lighting caused by damage.
4 to prevent splash of water intrusion: to prevent the splash of water from the water into the lamp damage.
5 to prevent the injection of water intrusion: to prevent the water from all directions from the nozzle into the lighting caused damage.
6 waves: the lights to prevent intrusion on the deck, to prevent the invasion and damage into the sea.
7 to prevent the intrusion of water immersion: lamps immersed in water at a certain time or water pressure in a certain standard to ensure that the water does not cause damage to the water.
8 to prevent the sinking of the water intrusion: the sinking of the light fixture in the specified water pressure conditions, can ensure that the water is not caused by damage.
IEC standard is IEC International Electrotechnical Commission standards referred to:
the International Electrotechnical Commission (International Electro technical Commission (IEC), founded in 1906, is in the world, the establishment of the first non-governmental international Electrotechnical Standardization Organization, ECOSOC (ECOSOC) of grade a consulting organization. After the ISO was established in 1947, IEC has been incorporated into the ISO as the electrical department, but in the technical and financial. According to the new agreement in 1976 ISO and IEC, the two organizations are legally independent organizations, IEC responsible for the international standardization of electrical and electronic fields, and other areas are responsible for the ISO. At present, the IEC member states include the vast majority of industrial developed countries and some developing countries. These countries have 80% of the world's population, the production and consumption of electricity accounted for 95% of the world, manufacturing and use of electrical and electronic products accounted for 90% of the world's output. The purpose of IEC is to promote the international harmonization of electrical standards, standardization and international cooperation in the field of electrical and electronic engineering, enhance mutual understanding between the international. To achieve this goal, the publication of a variety of publications, including international standards, and the hope that the State Council in the case of their own conditions permit, the use of these international standards. IEC's work areas include electrical, electronics, telecommunications, and atomic energy. IEC
's top authority is the council. Currently there are 53 member states, known as the IEC National Council, each country can only have one body as its members. Each member of the Council is a council member, the Council meeting once a year, known as the IEC annual meeting, held in turn in each member state. Executive Committee to deal with matters assigned by the council. IEC Technology (CA) is responsible for the executive committee. Executive Committee in order to improve the work efficiency, divided into a, B, C three groups, respectively in different areas and standard formulation of coordination work. IEC currently has 104 technical committees, 143 sub technical committee. IEC has three certification committee, one is the electronic components quality assessment committee (IECQ), one is the electronic safety certification committee (IECEE), one is the explosion-proof electrical Certification Committee (IECEX). In order to establish a unified certification standards, IEC is still in 1996 set up a qualified assessment committee (CAB), responsible for formulating a series of certification and accreditation standards including system certification work.
