Standard PN-EN 55015: Why must lighting meet its requirements?

Shortcuts

Electric lighting is no longer just a tool for everyday use; it has become advanced technology that requires strict adherence to rigorous technical standards for reliable operation. These requirements are particularly important in the context of the PN-EN 55015 standard, which defines acceptable levels of electromagnetic emissions (EMC regulations) from lighting devices. Meeting its criteria not only ensures user safety but also guarantees that the lighting does not interfere with the operation of other devices, a crucial factor in the increasingly complex electromagnetic environment of the European Union.

What is PN-EN 55015 and why is it important?

PN-EN 55015 is a standard that regulates the electromagnetic compatibility (EMC) of lighting devices, whether used in buildings or industrial environments. EMC refers to a device's ability to function properly without causing interference to other electronic systems. The standard ensures that lighting products are tested to confirm they don't emit electromagnetic disturbances that could affect other equipment.

Failure to comply with the PN-EN 55015 standard can result in lighting that, instead of simply providing illumination, disrupts radio signals, television operation, or other electronic systems. In fact, over 90% of lighting products tested by the RCC Research and Development Center failed to meet the requirements of this standard.

Where do interference issues come from?

Electromagnetic disturbances in lighting often arise from the absence of appropriate interference filters. This is especially common in low-cost products imported from outside the European Union, where manufacturers sometimes cut corners to reduce costs by omitting crucial components. Without proper filters, turning on the lights may disrupt radios, TVs, or other nearby electronic devices.

Well-designed lighting devices should include filters to prevent electromagnetic interference (EMI). LED lighting, for example, often causes issues. The LEDs themselves don't create disturbances, but their power supplies, which convert grid voltage to levels suitable for the LEDs, often do. These power supplies, especially in lower-quality products, tend to be poorly designed and lack necessary components for suppressing disturbances.

Consequences of failing to meet PN-EN 55015 standards

Non-compliance with PN-EN 55015 can have significant consequences. The Office of Electronic Communications (UKE) is responsible for monitoring the electromagnetic compatibility of products in the market. UKE can inspect products, and if non-compliance is found, it may order the removal of the product from the market. In severe cases, manufacturers or importers may be required to recall faulty products from consumers and face financial penalties. UKE publishes a list of non-compliant products on their website: https://bip.uke.gov.pl/lista-produktow-niezgodnych-z-wymaganiami/ .

Additionally, non-compliant products are reported to RAPEX, a rapid alert system for dangerous non-food products in Europe. This means that consumers across the EU are made aware of the issue, potentially damaging the manufacturer’s reputation and trust in their brand.

Interference in LED lighting installations

Electromagnetic interference is a common issue with LED installations. Although LEDs offer benefits like high energy efficiency and long lifespans, they can interfere with the operation of other electronic devices, such as radios, televisions, and computers. These disturbances are primarily due to low-quality power supplies used in cheaper LED fixtures, especially the converters that transform AC power from the electrical grid into DC power for the LEDs.

If poorly designed or low-quality converters are used, they can emit electromagnetic disturbances that impact nearby devices, particularly radios.

Types of interference in LED installations

LED systems generate two main types of interference:

  1. Conducted interference – disturbances that travel through the power network and affect other devices connected to the same electrical grid.
  2. Radiated interference – disturbances that spread through the air and directly affect nearby sensitive devices without using power wiring.

How to prevent interference in LED lighting

The key to avoiding electromagnetic interference lies in the quality of the components used. To ensure that an LED installation is free from interference, it is essential to use high-quality power supplies and drivers equipped with built-in EMI filters. Selecting products from reputable manufacturers who comply with European EMC standards, including PN-EN 55015, is crucial.

In addition to choosing quality components, proper planning of the lighting installation is equally important. For larger installations, such as in warehouses or production facilities, it's advisable to involve specialists in the design and setup. A poorly designed LED installation can cause interference issues that affect other equipment within the building.

It is also worth considering additional protective measures, such as surge protectors, which can safeguard the LED installation from voltage spikes caused by power surges, lightning, or other electrical grid issues.

RCC's role in electromagnetic compatibility testing

RCC Research and Development Center specializes in testing the electromagnetic compatibility of lighting devices. Our lab conducts comprehensive tests to help manufacturers and importers ensure that their products comply with the requirements of PN-EN 55015 and other relevant EMC regulations.

Our tests include both laboratory and real-world conditions, allowing us to detect potential issues with radiated and conducted interference. We aim to ensure that LED lighting on the market is safe for users and does not interfere with the operation of other electronic devices.

Additionally, using state-of-the-art equipment, we test the resilience of lighting devices to disturbances in the electrical grid, which they may encounter in real-world use. These requirements stem from other standards, but they are equally critical for lighting systems.

The importance of compliance with PN-EN 55015

The PN-EN 55015 standard plays a critical role in ensuring the safe and reliable operation of lighting systems in the European Union. Failing to meet its requirements can lead to serious consequences for both manufacturers and consumers. Lighting systems that emit electromagnetic disturbances can interfere with other devices in their surroundings, compromising the overall electromagnetic environment.
