The present invention relates to a plant factory, and more specifically, to a system which controls light sources for a plant factory in order to optimize the growth of plants. According to the present invention, a light source control system for a plant factory comprises: light sources which have different spectral distributions, and irradiate light toward plants in a cultivation area; a reference reflecting plate which is installed in said cultivation area, and reflects the light incident from said light sources; and a camera which measures ratios of the intensity in each wavelength region of the light reflected from said reference reflecting plate. According to the present invention, the light source control system for the plant factory controls the light sources after measuring the ratios of the intensity in each wavelength region of the light irradiated on the plants in real time, thereby maintaining optimized spectral distributions regardless of the duration of usage or changes in ambient temperature. |
