In recent years, with the continuous development of semiconductor lighting technology, double-ended LED tubes for general lighting have been rapidly developed and widely promoted in China. Europe is an important market for the export of lighting enterprises in China, but the European standard for the safety of LED lamps, EN 62776, has not been officially promulgated yet (the content of the draft version 34A/1501/NP was released as early as 2011), so it is currently the largest in Europe. The standards used by certification bodies for LED tube safety testing and certification are not uniform. In the design and manufacturing process, how to eliminate the safety risk of LED lamps replacing traditional double-ended fluorescent lamps, meet the requirements of certification standards, and successfully pass export certification to avoid the risk of recalled and banned products due to safety hazards? This article mainly discusses the current practices of major European certification bodies and the technical points that manufacturing companies need to pay attention to. (Remarks: IEC 62776 Ed. 1.0 Double-capped LED lamps designed to retrofit linear fluorescent lamps - Safety specifications will be officially released in December 2014; EN 62776:2014 is expected to be released later) European certification bodies use EN 62560 (LED self-ballasted lamp standard), EN 62493 and EN 62471 to issue CE certificates for LED tubes. EN 60061-1, EN 60061-3 for G5/G13 caps are also considered for evaluation and testing. Dimensional requirements and some provisions of EN 61195 (Double-head fluorescent lamps - safety specifications), such as lamp length measurement, lamp head torque test, etc. Product features: single-ended charging, one end is L / N, the other end of the two pins short circuit. Do not evaluate the Replacement Starter (Remarks: Replacement Starter refers to the internal short circuit of the replacement of the fluorescent starter or the starter containing the fuse, mainly the function of the connecting circuit). The instructions will stipulate that the LED tube can only be used in the lamp of the inductive ballast, replace the fluorescent tube with the LED tube, and replace the fluorescent starter with the Replacement Starter. A German certification body evaluates and licenses LED tubes using the standard E DIN EN 62776 (VDE 0715-16) (Double-capped LED lamps for general lighting services-Safety specifications). The product name is usually named LED lamp. Product features : single-ended charging, one end is L / N, the other end of the two pins short circuit. When replacing the fluorescent tube with the LED tube, it is not allowed to change the lamp line. The LED tube can only be used in the lamp of the inductive ballast. It needs a Replacement Starter. Only the LED tube can be used to replace the fluorescent tube. Replace the fluorescent lamp with the Replacement Starter. Hui. There is also a European certification body that issues CE certificates for LED tubes with EN 60598-1, EN 61347-2-13, EN 61347-1, EN 62031, EN 61195, EN 62493 and EN 62471. 34A/1501/NP (draft IEC 62776) is also considered for evaluation and testing. In addition, the dimensions of the G5/G13 base are evaluated using EN 60061-1, EN 60061-3, the tube size is evaluated with EN 60081, and the Replacement Starter is evaluated with EN 60155. The main line is placed on the 34A/1501/NP, and the focus of the assessment and testing is based on it. Product features: single-ended charging, one end is L / N, the other end of the two pins short circuit. It is not allowed to change the lamp line. The LED tube can only be used in the lamp of the inductive ballast. It needs a Replacement Starter. Only replace the fluorescent tube with the LED tube and replace the fluorescent starter with the Replacement Starter. In summary, although the standards used by major certification testing institutions in Europe for issuing LED tubes are not the same, the basic idea of ​​evaluating LED tubes is the same. In the near future, with the official promulgation of IEC/EN 62776, the practice of each certification body will be unified, so the technical points we will discuss are based on the current draft IEC 62776. Technical point analysis Draft IEC 62776 is applicable to LED lamps with double-ended G5 or G13 bases, rated power not exceeding 60W, rated voltage not exceeding 250V, LED lamps can directly replace fluorescent lamps without modifying or destroying existing lamps.
