LED lighting products in Europe and the United States market testing and certification status and analysis

With the increasing popularity of led lighting products, due to the considerations of product safety, reliability, and energy saving and environmental protection, products exported to Europe and the United States must pass corresponding inspection and certification, which is conducive to improving the quality of lighting products in the market. At the same time, it helps consumers quickly and accurately identify safe and energy-saving lighting products. Different from the detection and certification of general electrical and electronic products, products need to pay special attention to their optical performance and lumen maintenance characteristics in addition to the safety performance and electromagnetic compatibility of the product. Therefore, we first analyze the current LED lighting products exported to the European Union and the United States need to do what testing certification, and the need to pay attention to these issues in the detection process. Finally, it highlights the current U.S. ENERGY STAR certification that has the greatest impact on LED lamp inspection and certification, and shares some of our lab's testing research experience.

LED lamps exported to EU countries must pass CE certification. This certification requires products to pass the requirements of LVD and EMC directives. LED luminaire products The European Union CE certification LVD directive is 2006/95/EEC, the main test standards are EN60598-1, EN60598-2 series, EN61347-1, EN61347-2-13, EN62031 and EN62471.

Among them, EN60598-1 is a universal safety standard for lamps. For certain types of lamps, it is generally necessary to combine the special requirements of specific types of lamps in the EN60598-1 and EN60598-2 series to consider the safety features of the lamps. EN61347-1 is a general safety requirement for lamp controllers and EN61347-2-13 is a safety requirement for LED drivers. EN62031 is a safety specification for general lighting LED modules, markings, terminals, protective grounding, protection against electric shock, insulation resistance, electrical strength, fault condition, structure, creepage distance and clearance, heat resistance, Fire and anti-tracking, anti-corrosion, etc., are related to regulations. EN 62471 is a standard for evaluating the photobiological safety of lamps and luminaire systems. The light source includes LEDs, but does not include lasers. The standard classifies continuous radiant lamps into exempt categories and Class 1 hazards based on the degree of damage to light radiation. ), 2 types of hazards (medium hazards) and 3 types of hazards (high hazards) and other four categories.

The test items in the lamp type test mainly include: signs, structures, external lines and internal lines, protective grounding, protection against electric shock, dust, water and moisture resistance, insulation resistance and electric strength, contact current, creepage distance and electrical Gap, durability and thermal test, ball pressure, glow wire and needle flame test. In a large number of testing processes in our laboratory, it was found that test items with high probability of non-conformance generally include creepage distance and clearance, grounding resistance test, ball pressure, glow wire and needle flame test, and IP test.

LED lighting products EU CE certification EMC directive 2004/108/EC. The applicable test standards are EN55015 and EN61547. The EN55015 standard considers the requirements for product emission (ie, EMI). EN61547 considers the requirements for anti-interference capability (ie, EMS). If the product is AC-powered or can be connected to an AC power supply, additional tests EN61000-3-2 (current harmonics) and EN61000-3-3 (voltage flashing) are also required.

For the emission part of the lighting product, EN55015 has three test items in this standard: disturbance voltage test, electromagnetic radiation disturbance in the range of 9kHz to 30MHz and electromagnetic radiation disturbance in the range of 30MHz to 300MHz. Special attention should be paid to the fact that compared with the general products, the test of the electric field radiation only needs to be tested to 300 MHz without measuring 1 GHz.
