The introduction of LED waterproof power supply protection grade _

LED waterproof power supply protection grade, introduced in 2020-1151 05 - 12 16:55:16 LED waterproof power supply protection grade introduce LED waterproof power supply protection grade abbreviations for IP ( 国际保护) It is thus by IEC ( 国际电气技术委员会) The draft, will prevent outside content invasion, waterproof, dustproof, moisture proof features and classification of a proper noun. We usually see in lamps and lanterns and power IP * * is what we call protection grade, such as IP45, IP65, IP68, I think everyone has seen, but IP45, IP65, IP68 represent what they really mean it, it is to belong to what kind of protection grade? Below small make up to tell you: IP protection grade is composed of two Numbers 1, the first number said products dustproof, the level of the external things out; 2, the second number said product moisture proof, waterproof airtight degree. The greater the number, said the higher degree of protection. The first number of representative significance: 0 means no protection, the rest of the world people or things without special protective 1 invasion more than 50 mm solid objects, prevent the body ( Like the palm of your hand) Due to accidental contact of internal parts. Prevent the larger, Diameter greater than 50 mm) The external things of invasion. 2 said invasion more than 12 mm solid objects, prevent a person fingers touch the internal parts. To prevent the medium size ( Greater than 12 mm in diameter, length is greater than 80 mm) The external things of invasion. 3 means to prevent greater than 2. 5 mm solid objects invasion, prevent the diameter or thickness greater than 2. Tools of 5 mm wire or similar small objects into 4 said access to the internal parts to prevent greater than 1. 0 mm solid objects invasion, prevent the diameter or thickness greater than 1. 0 mm tools, electrical, or similar small objects into 5 said dustproof and access to the internal parts, completely prevent outside intrusion. Is not completely prevent dust intrusion, but the amount of intrusion of dust will not affect the normal operation of 6 dust tight completely prevent outside intrusion, and can completely prevent dust intrusion on behalf of the significance of the second number: 0 means no protection to the outside world of people or things without special protective 1 to prevent water intrusion, vertical drop of water droplets ( If the condensate) To not cause harmful effects when 2 said tilt 15 ° still can prevent water intrusion, when products from vertical tilt to 15 °, drop of harmful effects on the lamps and lanterns is not 3 means to prevent spray water intrusion, rain or on defense and the vertical Angle is less than 60 ° direction by spraying water into the product of 4 said damage to prevent splash of water invasion, prevent water from entering the product with different directions to damage 5 said to prevent injection water invasion, prevent from each direction by nozzle spray water from entering the product damage 6 said to prevent the invasion of the big waves, installed on the deck of the products, to prevent the damage caused by the descent of the big waves and flooding seven said to prevent flooding of water invasion, the product a certain amount of time immersed in water or water pressure under certain standards to ensure that no damage caused by water 8 said prevent water intrusion, sank product indefinitely designated water pressure under the condition of the sinking of the early, to ensure that no damage caused by water in general, LED waterproof power supply, generally require IP65. Of course, also want to see which applied to the occasion. Like the LED street lamp IP65 waterproof level can handle it. Occasions, like the indoor bathroom bathroom LED lighting, LED power supply IP53 can meet the need. If it is put out to sea with nautical lights, only IP68 level can be.
