What is the protection (IP) level of the LED power supply? How to test?
The protection (IP) level of the power supply is represented by IPxy, and x denotes dust-proof, which is the number 1-6; The y is the waterproof level, which is the number 1-8.
The following is the waterproof test content of various grades.
Firstly: IPXI method name Vertical drop test
a) testing equipment: dribble test equipment
b) sample placement: Make specimen of a plane and vertical into 15 °Angle, sample top to drop port distance not greater than 200 mm. After each try, change another face, four times.
c) duration of the test.: 10 min
Secondly: IPX2 method name Tilt 15 °drop test
a) testing equipment: dribble test equipment
b) sample placement: Make specimen of a plane and vertical into 15 °Angle, sample top to drop port distance not greater than 200 mm. After each try, change another face, four times.
c) test conditions: the drop of water is 3.5mm /min; Duration of test: 4 x 2.5 min (10 min total)
Thirstly: IPX3 method name: water pouring test
a) tube water test. testing equipment: Water splashing test device for swing pipe.sample placement: Selecting the appropriate radius of tube, in arranging the sample mesa height diameter position, put the sample in sample stage, make the distance from the top to the sample water is not more than 200 mm, samples not rotating.sample condition: The water flow is calculated according to the number of water holes in the swing pipe, each hole is 0.07 L/min. Drench water, 60 ° to each side of arranging the midpoint segment within the blowhole water spray to the samples. The sample was placed in the center of the swing tube semicircle. Tube is placed in vertical sides is 60 °, 120 °. Each swing (2 x 120 °) about 4 s.testing time: Continuous flow of water for 10 min.
b) Spray sprinkler test. testing equipment: Water spray test device for holding water. sample placement: The parallel distance between the top of the test and the nozzle of the hand nozzle is between 300mm and 500mm. sample condition: In the test, the baffle with balance weight should be installed, and the water flow is 10 L/min. testing time: According to the surface area of the tested sample, each square meter is 1 min (excluding the installation area), at least 5 min.
Fourly:IPX4 method name:water spray test
a) Swing pipe splash test. Test equipment and sample placement.: All of the above (3) IPX3 are the same; Test conditions: in addition to the following conditions, same as the above (3) IPX3. Water area for arranging the midpoint 90 ° to each side of segmental arc blowhole of hydraulic spray it to the samples. The sample is placed in the center of the swing tube semicircle. The swing pipe moves 180 degrees along the perpendicular line, about 360 degrees. Each swing (2 x 360 °) about 12 s.testing time:10 min
b) Spray water spray test.: Test equipment and sample placement.:The damper on the equipment shall be removed, and the rest shall be the same as the above (3) IPX3. test condition: Except for the following conditions, the same as the above (3) IPX3.testing time: Same as the above (3) IPX3.
Fifthly:IPX5 method name: spray experiments a) testing equipment
