There is a risk of insulation, domestic LED light cups have been repeatedly notified by the European Union

In the first half of this year, the total value of LED lamp cups exported to the EU in Ningbo was as high as US$20.3 million, a substantial increase of 125% compared with the same period last year. At the same time, however, since the beginning of this year, RAPEX has reached a total of 5 notifications on LED lamp cups made in China. The notified countries are concentrated in Finland, Germany and the United Kingdom. The main reason for the notification is the safety of products with poor insulation, which is easy to cause. The user is at risk of electric shock.

According to the statistics of the Ningbo Electric Safety Testing Center laboratory, in the first half of this year, a total of 52 LED lamp cup products were tested for safety, and the failure rate of insulation performance testing was as high as 40%. According to the analysis, the problem of non-conformity is mainly manifested in the following two aspects: 1. The breakdown or flashover occurs when the appliance is subjected to the withstand voltage test; 2. The creepage distance and clearance between the L and N poles of the lamp body are not reached. standard requirement.

From the perspective of unqualified reasons, it can be roughly classified into the following three categories: First, the industry threshold is low, the quality of production enterprises is uneven, and some family-run enterprises do not understand the international standards of products, and even do not know the existence of standards. Second, fierce market competition has caused some enterprises to give up the bottom line control of quality. In order to reduce costs, they intentionally cut corners and shoddy goods, resulting in the insulation performance of products not meeting the requirements of importing countries. Third, the quality management system of some enterprises is not perfect, and the mobility of first-line assembly employees is large, which leads to the stability and consistency of product quality cannot be effectively guaranteed.

To this end, the inspection and quarantine department reminds relevant enterprises: First of all, it is necessary to firmly establish the concept of "product quality is the first lifeline", and earnestly stress the integrity and quality in the production process. The second is to understand and thoroughly understand the relevant standard requirements, as a yardstick for product development and design work. At the same time, in the production process, it is necessary to make full use of the corresponding testing equipment, strengthen the self-inspection of the quality control points, and avoid the unqualified problems of products going abroad.
