50 V以上自镇流LED灯的安全要求
More than 50V Self-ballasted LED-lamp Safety Specifications
摘要 对50 V以上自镇流LED灯的安全要求,相比于GB 24906-2010,IEC 62560:2011增加了爬电距离和电气间隙的考核、自镇流LED灯的控制装置部分电子元器件断开和/或跨接试验,以及绝缘电阻和介电强度不同的试验要求,得出50 V以上自镇流LED灯IEC标准在安全、机械强度方面比国标有更高的要求。

Abstract For safety specifications of self-ballasted LED-lamps by voltage>50 V,compared
to GB 24906-2010,IEC 62560: 2011 adds the creepage distance and clearance tests
open and/or bridge points test in the circuit of control gear for self-ballasted LED-
lamps. The requirements of insulation resistance and electric strength tests are
different. Through analysis and comparison of these differences, it is concluded that
requirements of IEC standard on safety,mechanical strength are more rigorous than
them of national standard.
