<p>The present invention provides a lighting control device, a lighting control system, and a lighting control method to reduce power consumption and the fatigue of eyes of a person at the same time by providing optimal lighting according to an environment when illumination is controlled, which is a technical task for the present invention to accomplish. As a unit to solve the described technical task, the present invention provides the lighting control device which includes a control unit which controls the illumination of the light emitting unit according to each group with regard to a plurality of groups, wherein one group consists of a first illumination sensor and at least one light emitting unit. The control unit controls the illumination of the light emitting unit based on an illumination value measured in the first illumination sensor in the same group. At this time, the control unit controls the illumination of the light emitting unit to make one illumination value measured in the first illumination sensor a preset target illumination value. The lighting control device, the lighting control system, and the lighting control method according to the present invention control the light emitting unit to reduce the power consumption and the fatigue of the eyes of the person at the same time by providing the optimal lighting according to the environment when the illumination is controlled.</p> |
