室内照明用白光LED光源照度对人眼视网膜的影响研究

Study on the Human Retinal Security by Illumination of Indoor White LED

摘要:

针对白光LED光源对视功能影响进行医学实验研究，对不同照度下的各组大鼠视网膜电图进行检测，并比较不同光源照度对典型视网膜电图数据特征指标的影响。相对于正常对照组，300lux照度的白光LED光源照射下，大鼠视网膜电图数据基本无异常，个别特征出现差异趋势；1000lux照度的白光LED光源照射下，鼠视网膜电图数据异常，个别特征出现明显差异，因此，可以初步确定白光LED光源的安全阈值照度为300lux，LED光源照射下视网膜安全性的实验研究将为其进入室内照明应用提供理论基础。

Abstract:

Medical experiments were carried out on the influence of white LED on visual function and electroretinography (ERG) test results were obtained under different illuminations. Different characters of ERG under different illuminations were studied. Compared with the control group, by the 300lux illumination, no abnormal data can be found in ERG of rats and one of the characters of ERG shows different trends. By the 1000lux illumination, the data of ERG was abnormal and some characters of ERG show distinguished difference. So 300lux illumination can be determined as the safety threshold wavelength of white LED light source initially. Experimental study of the retinal security by LED light will provide theoretical basis for indoors application of LED light.
