The research results indicate that LED integrated photopanel as interior illuminant, which emit monochromic light such as red light(660～680nm)and blue light(430～450nm), not only cover with spectrums absorbed by the plant or algae for photosynthesis, enhance the light energy absorbed by chlorophyll a and the growth of Spirulina platensis, increase greatly microalgal biomass and the its content of photosynthetic pigments; but also decrease enormously the absorption spectrums not need for photosynthesis, save energy at more than 38.75%.

从LED集成光电板的光电特性、光热效应、光衰减性、光辐射特征与植物和藻类光吸收特征的相匹配性及LED辐射单色光对螺旋藻的光合色素含量的影响等几方面，分析研究了LED集成光电板作为光生物反应器内部光源的特性及可行性，研究结果表明，LED集成光电板作为光生物反应器的内部光源，它所发射的单色光谱红光660～680nm、蓝光(430～450nm，不仅能覆盖植物和藻类光合作用所需要吸收的光谱能带，促进叶绿素a对光能的吸收和螺旋藻的生长，增强光合作用，使细胞生物量与光合色素含量显著提高；而且不被吸收的光谱减少，节能达38.75％，无疑它将是光生物反应器潜在最有效的光源。
