现行蓝光危害评估均基于光源照度为500lx或距离200mm条件下进行,其测试条件与矿山的实际应用场景存在差异,特别是亮度、距离不匹配,且光源的色温与蓝光危害息息相关。为了研究蓝光危害的生物机理及危害程度的影响因素,研究分析了目前国内外IEC、CIE等权威组织对蓝光危害考核的相关标准,依据蓝光危害的计算方法,总结提出了蓝光曝幅限值的要求。结合矿井下LED光源应用的实际情况,设计了LED光源亮度、色温和照明距离3个重要因素对蓝光危害影响的测试方案。测试结果表明:蓝光危害与LED光源亮度、光源色温成正相关,蓝光危害与照明距离成负相关。研究指导了矿用LED防爆灯具的安全使用与防护,可为相关灯具等相关产品标准的制修订提供依据,具有较好的现实意义。

The current blue light hazard assessment standards are all based on the condition that the illumination of the light source is lx or the distance is mm. The test conditions are different from the actual application scenarios of the mine, especially the brightness and distance do not match,and the color temperature of the light source is closely related to the blue light hazard. In order to study the biological mechanism of the blue light hazard and the influencing factors of the hazard degree, the relevant standards of the blue light hazard assessment of the current domestic and foreign IEC,CIE and other authoritative organizations were studied and analyzed. The requirements of blue light exposure limit were summarized and put forward according to the calculation method of blue light hazard. The test scheme of the influence of three important factors of LED light source brightness,color temperature and lighting distance on blue light hazard was designed based on the actual situation of the application of LED light source in the mine. The test results show that the brightness and color temperature of LED light source are positively correlated with the blue light hazard,while the illumination distance is negatively correlated with the blue light hazard. The research guides the safe use and protection of LED explosion-proof lamps for mining,and provides a basis for the revision of relevant product standards such as lamps,which is of great practical significance.
