LED在建筑夜景照明节能中的应用探讨——以咸阳市渭城区一期亮化工程为例

Discussion on the Application of LED in Building Energy-saving Night Landscape Lighting in Weicheng District of Xianyang City: a Lighting Project as an Example

LED光源在建筑夜景照明中具有高效节能、使用寿命长、色彩丰富等传统光源无法比拟的优点。通过与传统光源参数的对比,结合咸阳市渭城区一期亮化工程实际功率密度值计算,得出LED实际发光效率高、耗能低的结论,对节能减排意义重大。尽管LED还存在一些缺陷,但通过改进将在夜景照明领域拥有更加广阔的应用前景。

The LED light source has the advantages of high efficiency,energy saving,long service life,rich color,and so on,which can not match with the traditional light source. Comparing with the traditional light source parameters,combined with a lighting project Weicheng District of Xianyang City,the actual power density value,the actual LED high luminous efficiency,low energy consumption of energy saving and emission reduction results,great significance. Although there are some defects in LED,the improvement will have a more broad application prospects in the field of night lighting.
