LED the application of how to identify the IP protection class of lamps and lanterns?

IP protection that IP protection grade standard is drafted by the IEC, the purpose is to the electric equipment according the characteristic of the dustproof, waterproof, such as grading. IP65 protection class IP to letters, figures for the tag number 6, 5 for the second tag digital dust, prevent invading level ( The first tag number) Digital protection scope statement 0 without protection to the outside world in people or things without special protective 1 to prevent greater than 50 mm solid invasion to prevent human body ( Like the palm of your hand) Due to accidental access to the internal parts, electrical appliances to prevent larger ( Diameter greater than 50 mm) The external things of intrusion 2 to prevent greater than 12. 5 mm solid objects into the parts inside the person's fingers come into contact with electrical, prevent the medium size ( Diameter greater than 12. 5毫米) External things into 3 prevent greater than 2. 5 mm solid intrusion prevent outside diameter or thickness greater than 2. 5 mm tools, electrical, and similar small outside intrusion and come into contact with electrical internal parts 4 to prevent greater than 1. 0 mm solid intrusion prevent outside diameter or thickness greater than 1. 0 mm tools, electrical, and similar small outside intrusion and come into contact with electrical parts may prevent foreign object inside and outside completely prevent dust intrusion, although not completely prevent dust intrusion, but into the amount of dust will not affect the normal operation of electrical 6 to prevent external things and completely prevent dust and dirt intrusion degree of moisture proof, waterproof into airtight second tag number digital protection scope statement 0 without protection of water and moisture without special protection to prevent water droplets into vertical falling water droplets (1 If the condensate) Won't cause damage to electrical 2 15 degrees tilt, still can prevent water intrusion when electrical appliances from vertical inclined to 15 degrees, drop of water will not damage to the appliance 3 to prevent spray water into rain or prevent with the direction of vertical Angle less than 60 degrees of damage by spraying water into electric 4 prevent splash water intrusion prevent various directions of damage water into electric 5 prevent injection water invasion to prevent from the direction of the damage caused by the water into electric powered by the nozzle 6 invasion wave installed on the deck of electric equipment, can prevent the damage caused by waves of seven to prevent flooding water into electric invade a certain time in the water or water pressure under certain standards, can ensure that no damage due to contamination of water 8 invasion of the sinking water appliances sank under the water pressure of specified indefinitely, to ensure no damage due to contamination of water so I know these, at the time of lamps and lanterns of choose and buy, should according to their own application needs to choose the lamps and lanterns of what protection grade!
