The waterproof level of LED lamps: the significance represented by IP68

As an important element in urban lighting, LED lighting fixtures are increasingly recognized by society. The standard that determines the quality of an LED lamp is its parameters. Among them, there is an important parameter: protection level!

Let Shenzhen Zhongke Lvneng Optoelectronic Technology Co., Ltd. explain in detail the meaning of the protection level represented by LED point light sources, LED wall washing lights, LED projection lights, LED mining lights, and other LED lighting fixtures.

The protection level system is drafted by IEC (International Electrotechnical Commission), which classifies electrical appliances based on their dust and moisture resistance characteristics. The external objects referred to here, including tools, and human fingers, should not come into contact with the live parts inside the electrical appliance to avoid electric shock. The degree of protection is often expressed in IPXY, where IP is the abbreviation for Ingress Protection and XY is the two digits representing the degree of protection. The first digit X indicates the range of dust resistance of the equipment, representing the level of prevention of solid foreign objects from entering, with a maximum level of 6; The second number Y indicates the degree of waterproofing of the equipment, representing the level of protection against water ingress. A larger number indicates a higher level of protection, with a maximum level of 8.

The first digit X represents the dust level:

0: No protection, no special protection for external people or objects

1: Prevent the intrusion of solid objects with a diameter of 50mm and larger, prevent the human body (such as the palm) from accidentally coming into contact with internal parts of electrical appliances, and prevent the intrusion of larger objects with a diameter greater than 50mm;

2: Prevent solid objects with a diameter of 12.5mm and larger from invading, prevent human fingers from touching internal parts of electrical appliances, and prevent foreign objects with a diameter greater than 12.5mm from invading;

3: Prevent solid objects with a diameter of 2.5mm and larger from invading, and prevent tools, wires, and similar small foreign objects with a diameter or thickness greater than 2.5mm from invading and coming into contact with internal parts of electrical appliances;

4: Prevent solid objects larger than 1mm from entering, and prevent tools, wires, and similar small foreign objects with a diameter or thickness greater than 1.0mm from invading and coming into contact with internal parts of electrical appliances;

5: Prevent the accumulation of harmful dust and completely prevent the invasion of foreign objects. Although it cannot completely prevent the invasion of dust, the amount of dust invasion will not affect the normal operation of electrical appliances;

6: Completely prevent dust from entering, completely prevent foreign objects and dust from entering;

The second number Y represents the waterproof level:

0: No protection, no special protection against water or moisture;

1: Vertically falling water droplets (such as condensate) will not cause damage to electrical appliances;

2: When the appliance is tilted vertically to 15 degrees, dripping water will not cause damage to the appliance;

3: Prevent the invasion of sprayed water, prevent rain, or prevent water sprayed in a direction with a vertical angle of less than 60 degrees from invading electrical appliances and causing damage;

4: Prevent splashing water from entering and preventing water from splashing from all directions from entering electrical appliances and causing damage;

5: Prevent the invasion of sprayed water, flush with water without any harm, and prevent water from all directions flying from the nozzle from invading the electrical appliances and causing damage;

6: To prevent the invasion of large waves, it can be used in the environment inside the cabin. Electrical appliances installed on the deck can prevent damage caused by the invasion of large waves;

7: It can withstand immersion in water for a short period of time (1m), and electrical appliances can be immersed in water for a certain period of time or the water pressure is below a certain standard, ensuring that damage is not caused by immersion;

8: Immersion for a long time under a certain pressure can ensure that the electrical appliance sinks indefinitely under the specified water pressure, ensuring that damage is not caused by immersion;
