LED light-quality adjustment device in plant factory

The utility model relates to a LED light-quality adjustment device in a plant factory, which refers to a device for simulation of natural light radiation by circuit control and mainly comprises at least one luminous module, at least one optical module corresponding to and coordinated with the luminous module, a control module realizes information connection with the luminous module and a power source module providing electric power as needed by operation of the luminous module and the control module, wherein with the structure and through coordination by the optical module, the luminous module will be adjusted as required to realize concentrated irradiation or uniform dispersion and carries out adjustment of light exposure intensity, light exposure distance and light exposure time and so forth in combination with setting of the control module, so that the advantage of the simulation of the natural light radiation is realized.
