It is reported that in 2012, the EU`s non-food Rapid Alert System (RAPEX) notification of 37 of China`s exports of LED lighting products. Which creepage distances or clearances are not fully caused by poor insulation performance and be informed 29.
Creepage distance means the shortest distance between two conductive parts measured along the insulating surface. Electrical clearance is the shortest distance between two conductive parts. Both reflect the important parameters of the electrical insulation properties. Creepage distances or clearances are not sufficient to cause the breakdown of a short circuit or equipment damage, and in severe cases can result in electric shock casualties. Therefore, the security considerations, must ensure that there is adequate creepage distance and clearance.
In order to protect the quality and safety of export LED lighting tube products, reduce Bulletin of Chinese products on the international inspection and quarantine departments to put forward three proposals to the enterprise. First, pay close attention to be familiar with the relevant product standards, understand and focus especially on the international regulations and directives of the European Union issued avoid quality problems, from product design source. Second is to strengthen aspects of product testing, and implementation of the test in strict accordance with the appropriate provisions of the standard terms. Creepage distances or clearances can generally be found through the electric strength test, measured by the instrument can also be used to specifically measure. Third enhance quality control ability, gradually improve the product design review, incoming inspection, process validation, finished product testing, and other aspects of the management system, establish a complete product quality chain.
