手持式电动工具中LED光源的蓝光危害测试与分析

Measurement and Analysis of Blue Light Hazard of LED Light Source in Motor-operated Hand-held Electric Tools

手持式电动工具采用LED光源进行精细化作业时,LED光源发出的光可能近距离照射到人眼带来蓝光危害的风险。目前大功率LED光源的广泛应用使得蓝光危害的风险越来越高。通过测试手持式电动工具中LED光源的蓝光情况,结合当前大功率单颗LED光源蓝光测试经验,给出了采用LED光源作为辅助照明的建议,可有效地避免LED蓝光危害风险。

When hand-held electric tools are used for fine operation with the LED light source,the light emitted by the LED light source may be exposed to the human eyes at close distance, which brings the risk of blue light hazard. At present, the widespread application of high-power LED light source makes the risk of blue light become higher. Therefore, by testing the blue light of LED light source in hand-held electric tools and combining the experience of blue light test of high-power single LED light source, this paper gives some good suggestions to use LED light source as auxiliary lighting, which can effectively avoid LED blue light hazard risk.
