红外遥控器是否在RED指令范围内
今天被问道一个RED指令问题,和大家分享。红外遥控器,发射管发出的红外线波长940um, 遥控器发射频率38kHz,请问此遥控器是否在RED指令内。
法规:
Whereas IR conventionally extends from 300 GHz to 430 THz, devices operating in the lower part of the IR spectrum, i.e. that between 300 GHz and 3000 GHz, which corresponds to wavelengths between 1mm and 100μm (far infrared) are subject to the RED. IR devices operating solely at higher frequencies do not fall under the RED.
这个是我的计算,不知对不对:
940um波长的红外线,
光速=波长*频率
频率= 299792458 m/s➗ 940um =425.3Ghz 在范围内。 不在,RED指令要求25MHZ-1000MHZ的 我想在解答这个问题前,需要弄清楚RED指令的Scope是什么,指令Scope原文如下:
This Directive establishes a regulatory framework for the making available on the market and putting into service in the Union of radio equipment.
他是针对Radio equipment,那什么是radio equipment呢?指令也有定义如下,所以他们针对那些通过无线电波进行连接的设备,我想你的产品是红外的,应该不落入这个scope吧。
‘radio equipment’ means an electrical or electronic product, which intentionally emits and/or receives radio waves for the purpose of radio communication and/or radiodetermination, or an electrical or electronic product which must be completed with an accessory, such as antenna, so as to intentionally emit and/or receive radio waves for the purpose of radio communication and/or radiodetermination; 唉! 肯定不是啦! 好多取暖器 遥控器都不需要符合red指令 radio equipment才需要RED,这个肯定不是 radio equipment才需要RED,这个肯定不是 学习了。。。。。。。。。。。 待WIFI那种要做RED
