The present invention relates to a light control system. The light control system comprising: a plurality of light sources (104) each configured to emit light within a predetermined spectral range, each of the plurality of light sources (104) being configured to illuminate a corresponding sub-portion (108) of a space (100), a sensor (106) configured to within the space (100), detect a location (112) of a human (114) or an animal； and a control engine (107) configured to control the plurality of light sources (104) based on the detected location (112) of the human (114) or the animal such that a subportion (108a) of the space (100) in which the human (114) or the animal is not present is exposed (116) to the light (118) within the predetermined spectral range at a predetermined threshold intensity. A method for exposing a sub-portion of a space with light within a predetermined spectral range at a predetermined threshold intensity is also provided.
