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.

Abstract:
Disclosed herein are a lighting switch apparatus and a lighting switching method, which can perform lighting control by blocking or passing light from a lighting device using a user's hand motion while the user may make input to a lighting switch by means of a capacitive touch on the lighting switch. The lighting switch apparatus includes a capacitive touch sensing unit for recognizing a user's touch. A hand motion visible light receiving unit receives visible light from a lighting device depending on motion of the user's hand. A control unit generates a touch-based lighting control signal based on results of touch recognition, controls the hand motion visible light receiving unit so that the user's hand motion-based signal is output based on the results of touch recognition, and generates a lighting control command by combining the lighting control signal with the user's hand motion-based signal.
