What is IK Rating for Street Led Lighting

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.

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.

At present, there are two main luminous surfaces for LED street lights on the market, one is covered with optic pc lens, which is generally a modular design led street light; the other is covered with tempered glass while PC or PMMA optics lens inside the luminaire, so tempered glass plays a protective role. These lamps are generally designed for full die-casting street lamps. When the PC lens is covered, the IK rating test can easily reach IK10, but when the covering surface is glass because the glass is easily broken under the impact, generally 4mm thick glass can only reach IK08, but more and more bidding projects require glass design and provide IK10 test report as well, which stop a lot of bidders. So how does the street light with glass pass the IK10 test? As a professional LED street light manufacturer, ZGSM has more than 17 years of experience in LED street light design. After learning about the latest project requirements, our engineers and glass suppliers have repeatedly researched and tested, through strict control of the tempering process temperature, to maintain glass consistency, and at the same time slightly increasing the thickness of the glass, coupled with a special buffer design, finally solved this problem, and successfully launched the Rifle series street lights with glass and passed the IK10 test.
