Generally, when buying LED lamps, you will often find that IK Rating is written in the parameters of some lamps. Many people don’t know what IK Rating is. So today Green tech Lighting will talk about what IK Rating is for led lights.
Before the appearance of the IK code, the anti-impact code often appeared together with the IP rating protection to indicate the level of its impact protection, such as IP65(9), which is distinguished from the code of the IP protection level by brackets, but it was later canceled internationally. It is marked with the IK code and is still in use today.
The IK level is an internationally accepted digital code used to indicate the protection level of electrical equipment enclosures against external mechanical collisions. For outdoor equipment, whether it is suspended, buried in the ground or placed outdoors, it needs to have corresponding IK requirements. According to the standards of IEC 62262:2002 and IEC 60068-2-75:1997, it is the protection ability of the electrical equipment shell to the internal equipment when it is impacted by external force. For LED lamps, it is simply whether the internal circuit of the lamp is dropped or impacted. Is it still working properly if it is damaged? In the lighting industry, it is necessary to make IK protection levels for outdoor flood lights, street lights, stadium lights and some special lights. After all, the use environment of these outdoor lights is often harsh, and it is necessary to check whether the protection level of the lighting product shell Meet industry and national requirements. Usually we use a spring impact hammer or a free fall pendulum to hit the lamp to determine its IK rating. The unit of IK rating is Joule.
So what are the IK ratings that we often use for led lighting?
In the IEC62262 protection level code, it consists of two numbers, namely IK01, IK02, IK03, IK04, IK05, IK06, IK07, IK08, IK09 and IK10. The 10 levels are divided into two groups of tests according to different levels of testing: the first group is the spring impact hammer test from IK01 to IK06. This group of tests has relatively small energy (from 0.14J to 1J) and is generally suitable for Indoor LED lamps such as downlights, high bay lights; the other group is a large pendulum test from IK07 to IK10, the test energy is larger (ranging from 2J to 20J), suitable for street lights, stadium lights, explosion-proof lights IK level test.
Each set of IK Code numbers represents a different anti-collision energy value. See the corresponding relationship between IK Rating and its corresponding collision energy f in the table below.
IK Rating chart:
|IK Code||Impact energy（J）||Explains|
|IK00||0||No protection.In the event of a collision, the LED lights will be damaged|
|IK01||0.14||=The impact of an object weighing 0.25KG from a height of 56mm on the surface|
|IK02||0.2||=The impact of an object weighing 0.25KG from a height of 80mm on the surface|
|IK03||0.35||It can withstand the impact of a 0.2KG object falling from a height of 140mm on the surface|
|IK04||0.5||It can withstand the impact force of objects weighing 0.25KG on the surface falling from a height of 200mm|
|IK05||0.7||It can withstand the impact of objects weighing 0.25KG from a height of 280mm on the surface|
|IK06||1||= it can withstand the impact of an object weighing 0.25KG from a height of 400mm on the led lights housing|
|IK07||2||=it can withstand the impact of an object weighing 0.5KG from a height of 400mm on the LED lamp housing|
|IK08||5||it can withstand the impact of an object weighing 1.7KG from a height of 300mm on the LED lamp housing|
|IK09||10||Can withstand the impact of objects weighing 5KG from a height of 200mm on the surface|
|IK10||20||Can withstand the impact of objects weighing 5KG from a height of 400mm on the surface|
In the LED lighting industry, general customers have IK Rating requirements for outdoor lighting and industrial lighting, so what are the corresponding IK ratings?
LED Street lights: IK07/IK08 LED Tri-proof batten: IK06/IK07; LED Explosion-proof lighting: IK08 or above.
What is IP Rating ?
The IP Rating describes the enclosure for electronic equipment according to the definition of the European Committee for Electro Technical Standardization.
IP is standing for Ingress Security, the security of the product versus ecological effects like strong things or fluids. The IP rating includes two figures which are describing the height of the protection versus these effects. The larger the number, the greater the protection.
First Digit – Solids Protection
The first number tells you just how well safeguarded the fixture protests solids– such as dust. The higher the number the more protected it is.
Second Digit – Liquid Protection
The second number is utilized to tell you about the degree of fluid protection: 0 being no protection as well as 8 being the highest offered level of protection.What is the connection of IP rating to LED luminaires?
IP Rating Table
|Numbers||Protection against solid objects||Protection against liquids|
|0||no protection||no protection|
|1||solid objects over 50mm, e.g. touch by hand||vertically falling drops of water, e.g. condensation|
|2||solid objects over 12mm, e.g. fingers||direct spray of water up to 15° from vertical|
|3||solid objects over 2,5mm, e.g. tools and wires||direct spray of water up to 60° from vertical|
|4||solid objects over 1mm, e.g. small tools, small wires||water spray from all directions|
|5||dust, but limited (no harmful deposit)||low pressure water jets from all directions|
|6||totally protected from dust||temporary flooding of water, e.g. ship decks|
|7||immersion bath between 15cm and 1m|
|8||immersion bath for long period – under pressure|
What is the connection of IP rating to LED luminaires?
The short article “LED Life Cycle– Impacts” explains a lot of points that require to be considered when creating a long- life efficient LED system with high ecological benefits.
Humidity is one factor for metal parts, links and also electronic gadgets to get damaged really quickly. They begin to wear away, so it is better to shield the LED system very carefully against humidity.
A lot more mindful choices need to be made for atmospheres like coastal environment, manufacturing facilities that are creating chemicals along with indoor pool.
However, the instant requirement for an IP rated fixture really is 2 layer – the capability to ward off water and also the capacity to not allow dirt to enter inside.
Protection from water intrusion is essential for all outside fixtures, or those components inside your home that need to be washed down or are mounted in an extremely humid environment.
Maintaining the interior mechnasisms of the light completely dry is really important. Without a strong IP certification to protect it, lights would fall short.
The 2nd application is for exceptionally messy settings.
Thinks of a grain storage space facility where dust is prevalent. Keeping dust from going into the lighting fixture is necessary as to stay clear of scenarios where a stimulate might be presented to the dust as well as create an explosion.
We have actually all seen the results of a violent dust explosion, so where safety and security is critical in a dusty atmosphere, make sure the fixture is capable of keeping the dust out
(As an aside, some atmospheres call for surge evidence fixtures, so never ever replace the need for an explosion evidence component with one that is only IP rated).
