(1) The electric light source of agricultural semiconductor lighting is the fourth generation of semiconductor solid-state light source - modern electric light source such as light-emitting diode;
(2) The spectrum of the electric light source can be accurately adjusted, and the light intensity, light quality and photoperiod can be controlled in real time;
(3) It can meet the needs of light environment regulation in various fields of modern agricultural production, and achieve the goals of high yield, high efficiency, high quality and stable production;
(4) Agricultural semiconductor lighting includes both visual lighting and non-visual categories. Among them, plant and edible fungus lighting belongs to the former, and livestock and poultry breeding lighting belongs to the visual category;
(5) Agricultural semiconductor lighting can completely break through the diurnal and interannual photoperiod laws of natural light lighting, and completely control the lighting conditions according to demand;
(6) Light environment regulation needs to be coordinated with the control of other environmental elements, comprehensive collaborative regulation. Facility horticulture semiconductor lighting is an emerging research branch of facility horticultural engineering discipline, is the most important component of agricultural semiconductor lighting, is an important field of semiconductor lighting non-visual application, China's facility horticulture needs to vigorously develop semiconductor lighting technology and equipment, accelerate the application process and industrialization development.
