In general, you will frequently discover that IK Rating is listed in various LED light specifications when purchasing LED lamps. A lot of people are unaware of what IK Rating is. Therefore, Grilights will discuss IK Rating for led lights today.
Prior to the invention of the IK code, the anti-impact code, which is separated from the code of the IP protection level by brackets, frequently appeared alongside the IP rating protection to identify the degree of its impact protection, such as IP65(9), but it was eventually discontinued globally. It is still in use today and is designated with the IK code.
An internationally recognized digital rating called the IK level is used to describe how well electrical equipment enclosures are protected against external mechanical accidents. Outdoor equipment must meet the necessary IK standards whether it is hanging, buried in the ground, or simply placed outside. IEC 60068-2-75:1997 and IEC 62262:2002 define it as the ability of the electrical equipment shell to protect the internal equipment when it is struck by an external force. It only matters if the internal circuit of an LED bulb is dropped or otherwise damaged. Is it still functional even though it is damaged? IK protection levels must be created in the lighting sector for outdoor floodlights, streetlights, stadium lights, and some specialty lights. After all, the environment in which these outdoor lights are used is frequently severe, thus it is important to determine the degree of protection provided by the lighting product's shell. satisfy both national and industry standards. The lamp is often smashed with a spring impact hammer or a free fall pendulum to obtain its IK rating. IK rating is measured in Joules.
What then are the IK ratings that we frequently apply to led lighting?
IK01, IK02, IK03, IK04, IK05, IK06, IK07, IK08, IK09, and IK10 are the two numbers that make up the IEC62262 protection level code. According to different testing levels, the 10 levels are separated into two sets of tests: the first group is the spring impact hammer test from IK01 to IK06. This group of tests has relatively low energy (from 0.14J to 1J) and is typically appropriate for indoor LED lamps like downlights and high bay lights; the other group is a large pendulum test from IK07 to IK10; the test energy is higher (ranging from 2J to 20J), and it is appropriate for street lights, stadium lights, and IK level tests for explosion-proof lights.
The anti-collision energy value is represented by each set of IK Code integers differently. See the table below for the link between IK Rating and its associated collision energy f.
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 Tri-proof batten: IK06/IK07
UFO LED High bay lights:IK07/IK08
Outdoor LED Stadium lighting:IK08 or above
LED Street lights:IK07/IK08
LED Explosion-proof lighting:IK08 or above
