Abstract：Focusing on the speed and efficiency, the effects of different spectra on the growth of chlorella vulgaris and isochrysis galbana Parke 8701 were investigated by using monochromatic LED (light-emitting diode) and fluorescent lamp as light sources. It was concluded that continuous spectra accelerate the top-growth-rate, blue light has the best efficiency, and the combination of them can obtain a good balance of speed and efficiency. For the purpose of measuring spectra as a parameter of irradiation quantitatively, spectra-absorbability-coefficient defined as the quanta-absorbability- efficiency of spectra for algae was calculated by means of absorption spectra of algae and emission spectra of light sources. Compared with the experimental results the coefficients of different light sources have a positive correlation to their efficiency for growth, so the coefficient can be used to elementarily quantify the relation between the spectra and the efficiency for growth.
