Discussion on common problems and controversies of LED certification

Date:14-06-2017

The rapid development of LED also led to a large number of people engaged in the LED certification, but sometimes because of the standard are not familiar with or understand the regulations, or because of lack of understanding of the LED itself, many people often cause errors of LED certification of the understanding. Today, I'd like to make a presentation on some of the common issues in LED lighting CE certification.

The first problem is confusion between LED lights and LED lights. With the formal implementation of the EN62560:2012 version, the European Union has a uniform standard for LEDLamp. EN62560 standard translated into Chinese LED for the flow of light safety requirements, is aimed at LED light source (LEDLamp), such as LED bulb, LED spotlight, and other direct replacement of incandescent bulbs of a class of products. Its characteristic is LED drive built-in, lamp holder is standard E27 or E40 or GU10 wait for standard lamp cap to connect the work of city electricity. The driving power of the LED lamp can be built-in or external, the light source can be LEDLamp, and the LED light engine can be used as the light source directly. The LED light source engine can be connected to the city power by the driving power, or can be operated directly without the power supply, but directly with the city electrical connection. LED lighting standard first need to refer to EN60598-1, and then based on the installation of the lamp or use to determine the special applicable standards, such as the most common LED downlight, its standard isEN60598-1/EN60598-2-2. Consider the security performance of the LED module EN62031.
When we can tell the difference between LED lights and LED lights, it is easy to understand the criteria for re evaluation.
Second question, the LED lamp or LED lamp test item is not understood. On the one hand, it is easy to confuse safety requirements with performance requirements or electromagnetic compatibility requirements; on the other hand, it is always assumed that LED lamps will have some very special testing items. There is no excuse for this, but most of us who work in the LED industry are not engineers. We don't need it and it's not necessary to make it so clear. However, it is necessary to establish some basic concepts. For example, the product structure appears creepage distance is not enough and product pressure can not pass, all of which belong to the requirements of safety testing. The product of radiation, conduction, lightning or harmonic does not pass, it belongs to electromagnetic compatibility in the project. Luminous flux, color temperature and intensity of light distribution are of course the content of optical property.
In addition, LED's most important test project should be an assessment of energy consumption. We say that LED how to save energy and environmental protection, you must have facts and a basis, and rely on data to speak. LED energy efficiency certification of the first the most basic requirement is that under the premise of ensuring product safety and not to external electromagnetic interference, the maximum power consumption of P rated luminous flux generated when the value of the P, at least to achieve ERP level in the A level; second is the most basic requirement of normal light after 1000 hours the reported loss rate is less than 5%. There are, of course, many other requirements for energy consumption certification.
