To note that the anti-moisture and dumped into the specifications, protection class of IP (INTERNATIONAL PROTECTION) by the IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION) the drafting of led driver 120w applications. Fixtures will be graded according to their characteristics of the dust-proof moisture. Foreign objects including tools, referred to here people's fingers Dengjun can not come into contact with live parts within the lamp to avoid electric shock. IP protection class is composed by two digital, one figures that the lamps from the dust level to prevent the intrusion of foreign objects, 2-digit lamp against moisture and water penetrated the closed level, the higher the number of protection rating more high.
A marked digital definition:
0 No protection: no special protection to the persons or things outside
1 to prevent solid objects greater than 50mm intrusive: to prevent the body (such as the palm of your hand) due to accidental contact with the internal parts of LED Flood light 10W . Foreign matter to prevent a larger size (diameter greater than 50mm).
2 to prevent solid objects greater than 12mm intrusive: to prevent a human finger come into contact with parts inside the lamp to prevent intrusion of foreign objects of medium size (diameter 12mm).
3 to prevent solid objects greater than 2.5mm invasion: Prevention of diameter or thickness greater than 2.5mm tools, wires or similar details of a small foreign object intrusion to come into contact with parts inside the lamp.
4 to prevent solid objects greater than 1.0mm invasion: Prevention of diameter or thickness greater than 1.0mm tools, wires or similar details of a small foreign object intrusion to come into contact with parts inside the lamp.
5 dust: to completely prevent the intrusion of LED Power Supply , though not completely prevent dust from entering, but the intrusion of dust and will not affect the normal working of the LED Floodlight 80W .
6 dust: to completely prevent the intrusion of foreign objects, and can completely prevent dust from entering the
The second labeled figure definition:
0 No protection: no protection
To prevent dripping water intrusion: a vertical drops of water droplets (condensate) on the lamp will not cause harmful effects.
2 tilt of 15 degrees can still prevent dripping invade: When lighting vertical tilt to 15 degrees, the water dripping on the lamp will not cause harmful effects
3 to prevent the spraying of water intrusion: rain, or to prevent the lamps of less than 60 degrees with the vertical angle between the direction of spraying water into the damage caused.
4 to prevent the splashing of water intrusion: to prevent water splash from all directions into the lamp to cause damage.
5 to prevent the jet of water intrusion: to prevent the lamps from the direction of the water injection nozzles into the damage caused.
Prevent the intrusion of big waves: the installation of lighting on the deck, into the damage to prevent the invasion of the waves.
7 to prevent the intrusion of water flooding: the LED Spotlight 30W is immersed in a certain period of time in water or water pressure below a certain standard to ensure that no water damage.
To prevent water intrusion in the sinking: lamps indefinitely sunk in the specified water pressure conditions, to ensure that the water caused the damage.
The IEC standard is the International Electrotechnical Commission IEC standard referred to as:
The International Electrotechnical Commission (International Electro technical Commission, referred to as IEC) was established in 1906, is the world's oldest non-governmental International Electrotechnical standardization bodies, Grade advisory bodies of the United Nations Economic and Social Council (ECOSOC). ISO was established in 1947, the IEC has served as the electrical department incorporated into the ISO, but technically, financially, still maintain their independence. According to 1976 ISO and IEC, the new agreement, the two organizations are legally separate organization, the IEC is responsible for the international standardization work related to electrical and electronic fields, and other areas by the ISO is responsible for. IEC members include the vast majority of industrial countries and some developing countries. These countries have 80 percent of the world's population, its production and consumption of electricity accounted for 95 percent of the world's manufacture and use of electrical and electronic products accounted for 90 percent of the world's production. The object of the IEC is to promote the international harmonization of electrotechnical standards, electrical, electronic engineering standardization and other interested parties of international cooperation, to promote international mutual understanding. To achieve this objective, publishing various publications, including international standards and hope that the National Committees in their national conditions permit, the use of these international standards. IEC areas of work including electrical, electronic, telecommunications and atomic energy, electrical technology.
The highest authority of the IEC Council. There are currently 53 member countries, known as the IEC National Committees, each country can only have a body as its members. Each Member State are members of the Council, the Council meeting once a year, known as the IEC Annual Meeting, held alternately in each member. Executive Committee Council matters assigned. The IEC's technical work by the Executive Committee (CA) responsible. In order to improve the work efficiency of the Board, is divided into A, B, C, three groups, respectively, in different areas to deal with the standard-setting work in coordination. IEC currently has 104 technical committees, 143 sub-technical committee. The IEC has three Certification Board, an Electronic Components Quality Assessment Commission (IECQ), an electronic security Certification Committee (IECEE), an explosion-proof electrical Certification Commission (IECEx). In order to develop a unified certification guidelines, the IEC is still set up in 1996 Conformity Assessment Board (CAB) is responsible for the development of system certification, including certification and accreditation criteria.
