LED applications to note the anti-moisture and dumping and other norms, IP (INTERNATIONAL PROTECTION) protection level system is IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION) by the draft. The lamps according to their characteristics of dust and moisture to be graded. The foreign objects referred to herein contain tools, human fingers and so on are not exposed to the live part of the lamp to avoid electric shock. IP protection level is composed of two digits, the first number of lamps that dust, to prevent the intrusion of foreign objects, the second number of lamps that moisture, waterproof intrusion of the degree of closure, the greater the number that the degree of protection high.
The first marked number defines:
0 No protection: No special protection for people or objects outside
1 to prevent more than 50mm of solid objects Intrusion: to prevent the human body (such as the palm of your hand) due to accidental access to the interior parts of the lamp. To prevent large size (diameter greater than 50mm) of foreign objects intrusion.
2 Prevents intrusion of solid objects larger than 12mm: Prevents human fingers from touching parts inside the fixture to prevent foreign objects from medium size (12mm in diameter).
3 to prevent more than 2.5mm of solid objects Intrusion: to prevent the diameter or thickness of more than 2.5mm tools, wires or similar details of small objects intrusion and contact with the internal parts of the lamp.
4 to prevent more than 1.0mm of solid objects Intrusion: to prevent the diameter or thickness of more than 1.0mm tools, wires or similar details of small objects intrusion and contact with the internal parts of the lamp.
5 dust: completely prevent foreign objects intrusion, although not completely prevent dust from entering, but the amount of dust intrusion will not affect the normal work of the lamp.
6 dust: completely prevent foreign objects intrusion, and can completely prevent dust from entering
The second marked number is defined
0 No protection: no protection
1 to prevent drip intrusion: vertical drops of water droplets (such as condensate) on the lamp will not cause harmful effects.
2 can still prevent the infiltration of 15 degrees when tilting: When the light from the vertical tilt to 15 degrees, the drip on the lamp will not cause harmful effects
3 to prevent the spray of water intrusion: rain, or to prevent the water with less than 60 degrees in the direction of the spray of water into the lamp caused damage.
4 to prevent splash of water intrusion: to prevent the direction of the splash of water into the lamp caused damage.
5 to prevent the injection of water intrusion: to prevent the injection of water from the nozzle from the nozzle into the lamp damage.
6 to prevent the invasion of large waves: installed on the deck of the lamps and lanterns, to prevent the invasion caused by the waves into the damage caused.
7 to prevent immersion in water when the water: the lamp immersed in water for a certain time or water pressure below a certain standard to ensure that damage is not caused by water.
8 to prevent submerged water intrusion: indefinite sinking of the lamp in the designated water pressure conditions, to ensure that no damage caused by water.
IEC standard is IEC International Electrotechnical Commission standard abbreviation:
International Electrotechnique (IEC) was established in 1906, is the world's first non-governmental international electrical standardization body, is the United Nations Economic and Social Council (ECOSOC) Class A advisory body. After the ISO was established in 1947, IEC was incorporated as ISO into the electrical sector, but remained technically and financially independent. According to the new agreement between ISO and IEC in 1976, the two organizations are legally independent organizations, IEC is responsible for the international standardization work in the field of electricians and electronics, and other areas are responsible for ISO. At present, IEC member countries include the vast majority of industrialized countries and some developing countries. These countries have 80% of the world's population, producing and consuming 95% of the world's electricity, 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 of electrical and electronic engineering, and international cooperation in relevant areas to enhance international mutual understanding. To this end, various publications, including international standards, are published and it is hoped that national committees will use these international standards in the context of their own conditions. IEC's work areas include electrical, electronic, telecommunications and atomic energy aspects of electrical technology.
The supreme authority of the IEC is the council. There are currently 53 member states, called IEC National Committees, each country can have only one body as its members. Each member of the Council is a member of the Council, the Council meeting once a year, known as the IEC annual meeting, held in various Member States. The Executive Committee deals with matters entrusted by the Council. IEC technical work by the Executive Committee (CA) is responsible. In order to improve the efficiency of the work, the Board is divided into three groups: A, B and C, which will deal with the coordination issues in the standard-setting work in different areas at the same time. IEC currently has 104 technical committees and 143 subcommittees. IEC has three certification committees, one is the Electronic Components Quality Assurance Committee (IECQ), one is the Electronic Safety Certification Board (IECEE) and the other is the explosion-proof electrical certification committee (IECEX). In order to unify the development of the relevant certification standards, IEC also established in 1996 the Conformity Assessment Committee (CAB), responsible for the development of system certification, including a series of certification and accreditation guidelines.
