对LED 光源发出光的光谱分布规律进行积分计算以评估LED 照明光源的蓝光能量比例，确定其光电转换规律。依据 IEC 62471：2006 Photobiological safety of lamps and lamp systems 对蓝光波长的划分，对380~500 nm波段的光谱能量进行积分计算，确定这部分光能量占可见光能量的比例。通过两个比例，换算出蓝光占照明光源输入能量的比例。最终依据GB 50034-2013《建筑照明设计标准》中对各类场所照度标准核定其安全范围。分别对国外和国内300余例LED照明光源的光谱曲线进行蓝光能量分析，并与常用典型电光源（如荧光灯、金卤灯）的蓝光能量进行对比，得出LED 光源蓝光能量低于常用典型电光源，作为普通照明安全的结论。

Spectrum distribution rules of the light from LED light sources are subjected to integral computation to evaluate the proportion of blue ray energy of LED light sources and determine photoelectric conversion rules of LED. According to the wavelength division of blue ray as IEC 62471:2006 Photobiological Safety of Lamps and Lamp Systems, the spectral energy at the wavelength of 380~500 nm is subjected to integral computation to determine the proportion of the energy of 380~500 nm light to that of visible light. The proportion of blue ray to the input energy of lighting source is calculated according to the two proportions, and then the safety scope of blue ray is verified according to the illumination standards for different places as specified in the GB 50034 - 2013 Standard for Lighting Design of Buildings. As indicated by the blue ray energy analysis of the spectrum curve of over 300 foreign and domestic LED light sources and the comparison with the blue ray energy of ordinary typical electric light sources (i. e. fluorescent lamps and metal-halide lamps), the blue ray energy of LED light sources is less than that of ordinary typical electric light sources, so LED light sources are safe in general lighting.
