Nemko Shanghai Ltd. 上海联广认证有限公司 灯和灯系统的光生物安全性 Photobiological safety of lamps and lamp systems Introduction Wavelength range of light Introduction Visible radiation Any optical radiation capable of directly causing a visual sensation. Note: There are no precise limits for the spectral range of visible radiation since they depend upon the amount of radiant power reaching the retina and the responsivity of the observer. The lower limit is generally taken between 360 nm and 400 nm and the upper limit between 760 nm and 830 nm. 可见辐射 任何具有能够直接引起视觉的光辐射。 可见辐射的光谱范围没有精确的界限，因为它取决于到达视网膜的辐射功率和观察者的响应度，下限一般在360 nm - 400 nm之间，上限在760 nm – 830 nm。 Introduction Ultraviolet radiation (UV) Optical radiation for which the wavelengths are shorter than those for visible radiation. Note: For ultraviolet (UV) radiation, the range between 100 nm and 400 nm is commonly subdivided into: UV-A, from 315 nm to 400 nm; UV-B, from 280 nm to 315 nm; and UV-C, from 100 nm to 280 nm. 紫外辐射 波长小于可见辐射波长的光辐射。 100 nm - 400 nm范围内的紫外辐射通常被分为：UV-A (315 nm – 400 nm)、UV-B (280 nm – 315 nm)、UV-C (100 nm – 280 nm)。 Introduction Infrared radiation (IR) Optical radiation for which the wavelengths are longer than those for visible radiation. Note: For infrared radiation, the range between 780 nm and 106 nm is commonly subdivided into: IR-A (780 nm to 1400 nm), IR-B (1400 nm to 3000 nm), and IR-C (3000 nm to 106 nm). 红外辐射 波长大于可见辐射波长的光学辐射。 780 nm到106 nm这个区域的红外辐射通常被分为：IR-A(780 nm – 1400 nm)、IR-B(1400 nm – 3000 nm)、IR-C(300 nm – 106 nm)。 Introduction Blue light hazard (BLH) Potential for a photochemically induced retinal injury resulting from radiation exposure at wavelengths primarily between 400 nm and 500 nm. This damage mechanism dominates over the thermal damage mechanism for times exceeding 10 seconds. 蓝光危害 由波长主要介于400nm与500nm的辐射照射后引起的光化学作用，导致视网膜损伤的潜能。如果照射时间超过10s，这种损害机理起主要作用，而且是损害机理的数倍之多。 Introduction Which products are required to perform IEC/EN
