摘　　要：针对LED照明光源备受关注的蓝光问题,实验室分别选取了色温相当的冷白、暖白色传统照明光源和LED照明光源,对其初始状态及使用一段时间后的光谱、辐射能量进行测试及分析。实验结果表明:①LED照明光源几乎不含传统照明光源中存在的紫外光成分;②LED照明光源中的蓝光辐射能量并不比传统照明光源多;③暖白色光源的蓝光辐射能量仅有冷白色光源的一半甚至更低;④随使用时间增长,LED光源中的蓝光辐射能量会有所增加。该实验结果有助于人们全面认识各种不同光源的发光特点及规律,避免不当使用造成的伤害。For the 'blue ray' problem of LED lighting sources, we tested and analyzed the spectrum and the radiate energy of selected cool white, warm white traditional and LED lighting sources respectively. The test results show that 1) LED lighting sources almost do not contain UV components which exist in the traditional lighting sources; 2) Blue rays' radiation energy in LED lighting sources is not more than that in traditional lighting sources; 3) Blue rays' radiation energy in warm white light sources is only half of or much less than that in cold white ones; 4) As time goes on, blue rays' radiation energy in LED lighting sources will increase. This article would help people to fully recognize the characteristics and laws of light in different light sources and to avoid damage caused by improper use.
