LED lights standard of the North American

　　LED lamps as a new product , currently existing North American product safety standards are not specifically targeted technical requirements for such products , LED products become a test subject in the industry. American UL laboratory for the current situation of this industry , is organizing the preparation of LED energy saving lamp safety certification standards UL8750, this standard is still a draft, has not been officially adopted as the certification standards. Thus, the certification test questions LED energy-saving lamps , temporarily not been completely resolved.

　　The basic principle of LED energy saving lamp is converted to AC power by switching DC power modules to supply power to the light emitting diode work . According to the basic principles and structural features LED energy-saving lamps , the United States MET Laboratories detection scheme proposed a transitional stage : the traditional energy-saving lamps American certification standards UL1993 ( corresponding Canadian Standards CAN/CSA-C22.2No.0, CAN / CSA-C22.2No.74), and power modules standard UL1310 or UL1012 ( corresponding Canadian Standards CAN/CSA-C22.2No.107) LED energy-saving lamps for testing and certification .

　　LED lamps can be made into various shapes to fluorescent tube LED energy-saving lamps, for example , with its shape , like an ordinary fluorescent tubes , fluorescent tube by a transparent polymer shell of the power module and the light-emitting diode package inside. Transparent polymer shell fire and electric shock function to play in the product . According to the standard requirements, energy-saving lamp housing material is required to achieve V-1 level above , and therefore must be transparent polymer shell V-1 grade or more materials used .

　　Due to the limited internal space LED energy-saving lamps in the structural design , pay attention to insulation requirements dangerous live parts and accessible metal parts between . Insulation can be a spatial distance and creepage distances , it can be an insulating film. According to standards , between hazardous live parts and accessible metal parts spatial distance to reach 3.2 mm creepage distances to reach 6.4 mm . If the distance is not enough, you can add insulation sheet as additional insulation , insulation thickness greater than 0.71 mm , if the thickness is less than 0.71 mm , the product will have to be able to order of the 5000V high voltage testing.
