选取有着较高经济价值的纤细角毛藻以及亚心形扁藻为实验对象,在光照恒温培养箱中用红、绿、蓝、白LED集成不同光谱成分的光源与传统荧光灯进行对照培养实验。通过对比生长速率表明,与荧光灯光源相比光谱集成LED光源更有效地促进微藻的生长。说明LED集成光源作为微藻生长照明光源有其明显的优势。

Two kinds of marine microalgae,chaetoceros gracilis and platymonas subcordiformis which have high economic value as research object,are setected to do the culture experiment in incubator with light red,green,blue,white-LED spectrum of different combinations compareing with the traditional fluorescent. By comparing the growth rate with the fluorescent light,it′s showed that LED light source spectral composition is more effectively to promote the growth of microalgae. The obvious advantages of LED as light source of microalgae are indicated.
