| 中文摘要: |
| 随着人们生活水平的提高，老年人的视觉健康得到了越来越多的关注。从老年人生理、心理两个方面，探讨了老年人对照明的要求。通过对老年人视觉数据的分析，发现老年人生活环境的照明要求应满足：照明光源相关色温在3 300 K以下;照明光源的显色指数（Ra）不小于80；亮度选择在2 000 cd/m2以下（尽可能在1 000 cd/m2以下）;眩光值应小于19；对于波长宜选择橙色波段（595~620 nm）的光。满足这些照明要求可让人感到舒适、轻松，并在一定程度上可以使人更加有精神。 |

| With the improvement of living quality,people put more and more attentions on the visual health of the elderly.We analyze the requirements on the illumination from dual perspectives of physiology and psychology of the aged.By analyzing visual data of the elderly,we find that in the elderly's living room,the requirement of the lighting source's color temperature should be below 3 300 K and color rendering index (Ra) should not be less than 80.The elderly should choose lamps which brightness are below 2 000 cd/m2(as far as possible below 1 000 cd/m2).As for glare,we suggest that the unified glare value of the elderly's living place should be lower than 19.Comparing with the different wavelengths of light,the light of the orange band (595~620 nm) can let a person feel comfortable and relaxed,even more spirit to a certain extent. |
