通过北美地区普遍使用的 ANSI/UL 8750 标准认证，
还可以为同时符合 IEC 和 UL 标准的灯具提供双重绝缘 (DI) 认证标志
ANSI / UL 8750, standards of light emitting diodes (LEDs) for lighting products equipment, including independent appendix supplement SK. This appendix uses UL 2097, the reference standard for double insulation systems used in electronic equipment, to evaluate the double insulation of LED lighting equipment. UL 8750 can make double insulation certification mark for LED lighting equipment.
ANSI/UL 8750，即适用于照明产品所用发光二极管 (LED)设备的标准，包括独立附录补充 SK。本附录使用 UL 2097，即电子设备所用双重绝缘系统的参考标准，来评估 LED照明设备的双重绝缘。UL 8750 可以使 LED 照明设备包含双重绝缘认证标志。
In the past, double insulation (or reinforced insulation) certification marks were common in IEC lighting standards, such as IEC 60598-1 and IEC 61347-1, but rarely appeared in North American lighting standards. There are mandatory grounding requirements for lighting installations in American electrical law ® (NEC ®) 2017 and earlier versions. The electrical law NEC 2020 (Chapter 410.42) has revised this to allow lighting equipment without grounding circuit can get double insulation certification mark. In response to this change, UL 8750 is hereby revised to make it possible for LED lighting devices to obtain double insulation certification marks.
此前，双重绝缘（或加强绝缘）认证标志在 IEC 照明标准中较常见，比如 IEC 60598-1、IEC 61347-1 等，但在北美照明标准中鲜见出现。美国电工法 (NEC) 2017 版及之前的版本中对照明装置有强制的接地要求。电气法 NEC 2020版（第 410.42 章）对此进行了修订，允许带有双重绝缘认证标志的照明设备可以不提供接地。为呼应这一变化，UL8750 特此进行修订为 LED 照明装置获得双重绝缘认证标志提供了可能。
