Abstract：In order to accelerate the industrialization and scaled application development of LLPH , science issues in LLPH include two aspects .One issue is photobiology , to clarify the responsive mechanisms of physiology, molecular biology and proteomics of plant and edible fungi under monochromatic and compound light;Interspecific and intervarietal variations of light quality utilization for plants and edible fungi;interaction mechanisms between light quality and other environmental factors;available thresholds and critical values of light quality ( i.e.compensation point, saturation point, and stress thresholds ).The other issue is stress photobiology, to clarify the influences of weak lighting , strong lighting and continuous lighting of LED monochromatic or compound light on efficiencies of photosynthetic apparatus and metabolism systems .Three technology issues should be considered , including ( 1 ) optimal light recipes for high productivity; ( 2 ) establishment of light environmental control strategy for various production fields;(3) development of LED light source devices, lamps and intelligent control systems .
