注解!
此产品已通过测试,符合标准 IEC62471:2006“灯和灯系统的光生物学安全性”的要求。 此产品排放量
超过 IEC 62471:2006 定义的视网膜蓝光和角膜/镜片红外危险的豁免组限制。 此产品被发现符合风险
1 的红外和白光 LED 的暴露限制。
IEC 62471 提供一些方法来确定灯或装有灯的产品的风险组。 IEC 62471 中的风险组指示潜在的光辐
射危害的风险度。 风险组是根据几十年的灯使用经验以及与光辐射相关的意外伤害的分析制定的。
豁免组 没有光学危险被认为可合理预见,即使连续、无限制使用,情况也是如此。 典型示例是国内应
用场合中使用的大多数磨砂白炽灯和荧光灯。
风险组 1除了长时间暴露(在其中预计会发生直接眼睛接触)之外,对于大多数使用应用场合,产品
是安全的。 风险组 1 的示例是国内电池供电的手电筒。
暴露危险值 (EHV) 是暴露级别(距离、暴露时间)与暴露限制值 (ELV) 的比率。 如果 EHV 大于 1,该
设备已超过特定风险组的暴露限制值。 ELV 是预计光辐射到眼睛或皮肤不会造成不良生物效应的级别。
危险距离 (HD) 是到源的距离,在该位置处,暴露级别等于相应的 ELV 换而言之,对于特定风险组,
此时 EHV=1
关于此产品的角膜/镜片红外危险,基于豁免组暴露限制, 200 毫米的测试距离处,暴露危险值 (EHV)
2.19 基于风险组 1 限制的 EHV 0.386 豁免组的危险距离为 297 毫米。
关于视网膜蓝光危险,基于豁免组暴露限制,在 200 毫米的测试距离处,EHV 22.9 基于风险组 1
限制的 EHV 0.266 豁免组的危险距离为 2675 毫米。
