摘　　要：利用光栅光谱仪对几种常用光源的蓝光危害进行测试与分析,实验测量了多种常用光源的光谱,基于测量数据,计算了各种光源的蓝光比,得到白炽灯的辐射覆盖了整个可见光区,而LED光源的蓝光占比较大.The spectrometer was used to test and analyze the blue light hazards for several commonly used sources.The spectrum of variety of common light sources were measured experimentally,and the blue light ratio of various sources were calculated.The results showed that the radiation of the incandescent lamp covered the whole visible light area,while the blue light ratio of the LED light source was much larger.

关 键 词：蓝光 光栅光谱仪 LED
