EN 62471 标准 "灯具和灯具系统的光生物安全 "将照明光源分为一系列风险组别：
•风险组别 (RG) 0 = 无害/无光生物危害，即使连续、不受限制地使用也是如此
•风险组别 (RG) 1 = 低风险/因正常行为限制而无危险
•风险组别 (RG) 2 = 中度风险/由于对强光源的厌恶反应或热不适不会造成危害
•风险组别 (RG) 3 = 高风险/即使是挥发性或短期照射也有危险
光辐射可能对眼睛和皮肤造成伤害！
根据 IEC 62471:2006（工作距离 20 厘米，脉冲长度 10 毫秒，占空比 10%），该设备属于 2 类风险。
•操作期间请勿直视照明设备。
•工作站必须与设备保持标准规定的最小距离。
•与观察者有关的风险取决于设备的安装和使用。
信息：
根据颜色的不同，输出功率相同的 LED 可能属于不同的风险组别。颜色的波长越短（即向蓝色或紫外线方向移动），发出的光的能量就越高。
有关光生物安全的更多信息，请参见光生物安全。
•保护邻近工作场所不受 LED 照明光锥的影响
•防止进入危险区域的围栏
•降低强度（限制 LED 的工作周期 组织保护措施
•限制在 LED 照明附近的停留时间（遵守最长暴露时间的规定）
•与危险有关的风险组别标识
•危险区域的标记
•无论使用何种光色和光脉冲持续时间长短，都应避免直视 LED 照明。
•在 LED 照明附近逗留时，必须使用适当的安全护目镜或防护服（紫外线）！
The standard EN 62471 "Photobiological safety of lamps and lamp systems" divides lighting sources into a series of risk groups:
•Risk group (RG) 0 = Harmless / no photobiological hazard, even with continuous, unrestricted use
•Risk group (RG) 1 = Low risk / no danger due to normal constraints of behaviour
•Risk group (RG) 2 = Moderate risk / does not present a hazard due to aversion reactions of bright light sources or thermal discomfort
•Risk group (RG) 3 = High risk / danger even for volatile or short-term irradiation
Possible injuries to eyes and skin due to optical radiation!
The device corresponds to risk group 2 according to IEC 62471:2006 (at working distance 20 cm, pulse length 10 ms, duty cycle 10%).
•Do not look directly into the lighting during operation.
•Workstations must maintain the minimum distance to the device specified in the standard.
•The risk related to the observer depends on the installation and use of the device
Information:
Depending on color, LEDs with the same output power could be in different risk groups. The shorter the color's wavelength (i.e. moving in the direction of blue or UV), the more high-energy the emitted light is.
For further information on photobiological safety see Photobiological safety.
•Protection of adjacent workplaces against the light cone of an LED lighting
•Enclosures preventing access to the danger zone
•Reduction of the intensity (limitation of the duty cycle of the LEDs) Organisational protective measures
Organisational protective measures
•Limitation of the residence time in the vicinity of the LED illumination (compliance with the maximum exposure time)
•Hazard-related labelling of risk groups
•Marking of the danger area
•Avoid staring directly into an LED illumination, regardless of the light colour used and the duration of the light pulse.
•When staying in the immediate vicinity of LED lighting, appropriate safety goggles or protective clothing (UV) must be used!
