Question: What rules and approval procedures apply to LED lighting devices?

Summary:The FCC’s Office of Engineering and Technology (OET) has clarified that all RF LED lighting devices falling under FCC Part 15 rules as “unintentional radiators”must meet conducted and radiated emissions limits set forth in those rules.The OET clarifies radiated emissions measurements must be performed at leastfrom 30 MHz to 1000 MHz to adequately demonstrate compliance with FCC Part15 (§15.109).The OET clarifies that all RF LED lighting devices, even those that have beenconsidered to operate on frequencies below 1.705 MHz in the past, are required tohave radiated emissions measurements performed at a minimum from 30 MHz to1000 MHz.  所有射频LED灯具的无意发射都需要依据FCC PART 15评估传导与辐射。

Exempt:Fluorescent lighting devices, and LED retro-fit tubes intended to replace linearfluorescent tubes operated by RF ballasts, are subject to compliance with FCC Part 18 and are not addressed in this guidance document.Incandescent lamps are not considered RF devices.LED lamps powered by internal direct current (DC) power sources, without RFcircuitry (operating at greater than 9 kHz), with a passive LED array load anddelivering only DC current to LEDs, are not considered RF devices. 荧光灯、用在配合荧光灯镇流器里面在LED灯具、符合FCC PART 18且不在这个指导文件中明确指出的灯具、内部纯直流电池供电且内部任何频率不大于9kHz，可以从此指导文件豁免。但是，注意可能需要考虑FCC PART 18。
