    Abstract: An apparatus and method for controlling lighting are disclosed. The apparatus includes a reception unit, a determination unit, a state determination unit, and a lighting control command transmission unit. The reception unit receives an event message from a light sensor. The determination unit determines whether the event message is an event message attributable to a change in luminance or an event message related to a DALI system. If it is determined that the event message is the event message attributable to a change in the luminance, the state determination unit determines the luminance change state of a lit space using the event message attributable to a change in the luminance. The lighting control command transmission unit sends a lighting control command corresponding to the luminance change state using a control group address.
