What is IP Grade?

What is an IP66 waterproof rating LED fixture? What is the IP rating, why is it always displayed on LED electronics?

what is the IP meaning

IP is an international standard that protects the electronic enclosure from external objects, dust and water. The standard was promulgated by the International Electrotechnical Communications (IEC) to help classify appliances. These classifications are based on two key factors preventing dust, intrusion and water penetration.

With the strengthening of people’s safety awareness, the purchase of LED light is not limited to lighting and heat dissipation issues. Dust and water resistance have become another requirement for everyone.

If you’ve been buying or planning to buy lighting electronics, then knowing the IP rating will come in handy in some way.

This knowledge can help you find the best product for your specific needs.

Protection level of led light

What is the meaning of the IP rating standard (number)?

Typically, the IP rating is represented in the format -IPXY – XY consists of two different numbers.

For example, X in IPXY means that the device can prevent foreign matter (such as dust, tools, fingers (to avoid electric shock), insects, etc.) from intruding.

For example, Y in IPXY indicates the degree of protection of the device from water and moisture permeation.

The following is a brief breakdown of the meaning of each number in the IP rating.

1. IP grade dust or object resistance rating (IPX*)

0: no protection

1: Prevent large solids from immersing

2: Prevent medium-sized solids from invading

3: Prevent small solids from immersing

4: Prevent solids greater than 1mm from entering

5: Prevent harmful dust accumulation

6: Completely prevent dust from entering

2. IP grade waterproof or moisture resistant grade (IP*Y)

 0: no protection

1: Drops of water dripping into the casing have no effect

2: Water or rain drops from the 15 degree angle to the outer casing without affecting

3: Water or rain drops from the 60 degree angle to the outer casing without affecting

4: No impact on water at any angle

5: Low pressure injection at any angle has no effect

6: High pressure jet water has no effect

7: It can withstand water in a short time (15cm-1cm, within half an hour)

8: Soaking water for a long time under a certain pressure

The IP rating consists of two numbers, the first number indicating dust protection and the second number indicating water resistance. A larger number indicates a better level of protection.

 So the question is, what are the conditions for the IP65/IP66 waterproof test for the streetlights inside the company? What methods do you use for IP66 testing? Demonstrate an example here.

LED light IP Rating

Not all application scenarios have the same level of protection, and they have different levels of protection for indoor and outdoor LED lights. The degree of protection or IP rating is an important consideration when selecting LED lighting products for any project. It reflects the suitability of luminaires for specific environmental conditions in indoor and outdoor installations.

Now, let’s look at the different IP levels to see how they work.

LED lights for IP20 or IP40 Rating:

LED lights of IP20 or 40 are used for enclosed fixtures or indoors. It is usually good indoors unless it is in areas of high humidity or other harsh conditions. IP20 or IP40 lamps must not be outdoors unless they are sealed.

LED lights for IP54 Rating:

LED lights with IP54 protection are fully protected against dust. For liquids, it only prevents splashing. This is common in basic LED lights and indoor lighting.

LED lights for IP65 Rating:

The IP65 rating is considered the perfect choice for both domestic and commercial use, providing complete protection against foreign objects and water jets. If you buy outdoor lighting, it should be IP65 rated.

LED lights for IP67 Rating:

The IP67 protection provides full protection against solids and water ingress. They are similar to IP65 and IP64, and the protection against liquids is the same. However, LED lamps with this rating are more resistant to water than IP65. Even if the lamp is immersed in water at a depth of 1 M, the water will not affect it.

Here is an introduction for everyone:  led lights waterproof

Test Mothod

The test is made by spraying the enclosure from all practicable directions with a stream of water from a standard test nozzle as shown in figure 6.

The conditions to be observed are as follows:

– internal diameter of the nozzle:12.5 mm;

– delivery rate:100l/min

– water pressure: to be adjusted to achieve the specified delivery rate;

– core of the substantial stream: circle of approximately 120 mm diameter at 2,5 m distance from nozzle;

– test duration per square metre of enclosure surface area likely to be sprayed: 1 min;

– minimum test duration: 3 min

– distance from nozzle to enclosure surface: between 2,5 m and 3m.

After the test is completed, there are some check methods:

  1. The site has sufficient water, it is best to build a cistern or prepare a bucket
  2. The ground and the wall should be treated with ceramic sheets to prevent the spattered water from damaging the wall.
  3. The venue should be ventilated and open, the length of the room should be 3.5 meters long and the width is about 2.5 meters.
  4. Prepare three-phase power to meet the needs of the pump head

IP65 is dust-tight (no dust in) and water-proof (no harmful effects from water spray in all directions), which can completely prevent dust from entering. When subjected to strong wave impact or strong water spray, the water intake of the appliance should not reach harmful. Impact.

IP66 is dust-tight (no dust in) and anti-high pressure jet water, which can completely prevent dust from entering. When the high-pressure violent water is sprayed, the appliance is not in trouble.

Do you understand this knowledge? You can now shop by the importance, condition and adaptability of IP ratings.

A qualified LED light not only has good image and full function, but also has a high safety protection factor. Such a light is what the public wants.
