Abstract:
Disclosed herein are a Zigbee lighting control apparatus and method. The Zigbee lighting control method includes checking whether a Zigbee switch to which a Zigbee lighting control apparatus is applied is in a reset state, performing a broadcast-based link connection a number of times identical to a number of currently installed Zigbee lighting devices if the Zigbee switch is in the reset state, performing a broadcast-based link connection a number of times identical to a preset number of Zigbee lighting devices if it is checked that the Zigbee switch is not in the reset state, performing a unicast-based link connection on remaining Zigbee lighting devices that are not connected to a link, among Zigbee lighting devices within a preset range upon performing the broadcast-based link connection, and controlling Zigbee lighting devices that have been connected via the broadcast-based link connection or the unicast-based link connection.
Abstract:
A lighting control device and method are disclosed herein. The lighting control device includes a control unit and a control request unit. The control unit sets up a virtual multiple lighting control unit corresponding to a lighting control command received from a lighting management device. The control request unit selects a wireless light fixture corresponding to a light fixture ID included in the lighting control command, and makes a lighting control request to the selected wireless light fixture. The control unit transfers a response to the lighting control request to the lighting management device, and thus allows a corresponding lighting switch to control the wireless light fixture.
Abstract:
An individual lighting control apparatus and method are disclosed herein. The individual lighting control apparatus includes a reception unit, a terminal connection unit, a sensor unit, and a lighting environment sensing and terminal state determination unit. The reception unit receives the location information of a corresponding individual illumination light. The terminal connection unit acquires the state information of a terminal corresponding to the location information of the illumination light. The sensor unit acquires the sensor information of the set surrounding area of the terminal. The lighting environment sensing and terminal state determination unit sets operation mode based on the state of the connection with the terminal, and then monitors the state of the terminal or the state of the set surrounding area of the terminal in accordance with the set operation mode. The individual illumination light is controlled by providing state change information to a lighting control scheduler.
Abstract:
An apparatus and method for determining the location of a terminal are disclosed herein. The apparatus includes a reception unit, an initiation unit, a selection unit, and a correction unit. The reception unit receives the location identifications (IDs) of one or more illumination lights. The initiation unit initiates the location coordinates of a receiving terminal to the coordinates of an illumination light corresponding to the most frequently received location identification (ID). The selection unit selects the coordinates of an illumination light corresponding to the second-most frequently received location ID. The correction unit calculates the reception ratio of reception from the coordinates of the initiated illumination light to reception from the coordinates of the selected illumination light, and then corrects the coordinates of the receiving terminal based on the calculated reception ratio.
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.

The present invention relates to an intelligent lighting control apparatus and method, which control an intelligent lighting unit including multiple sensors depending on time, place, scene, environment, or the like, based on the results of sensing by the sensors. The intelligent lighting control apparatus includes a multi-sensor unit including multiple sensors, the multi-sensor unit sensing motion of a person or an object within a set sensing area using at least one of the multiple sensors. A lighting control unit controls an operation of a lighting unit based on frequency data corresponding to results of sensing by the multi-sensor unit and a class of lighting type corresponding to the frequency data.
Abstract:
The present invention relates to a motion sensor and method of operating the motion sensor, which can adjust the range of a detection area. For this, the motion sensor according to the present invention includes a detection unit for outputting a variation signal corresponding to motion. A threshold level setting unit variably sets at least one changeable threshold level. A comparison unit detects the motion by performing a comparison operation based on the changeable threshold level and the variation signal at threshold sensitivity corresponding to the changeable threshold level.
Abstract:
Disclosed herein are an apparatus and method for visible light communication using electrically switchable glass. The apparatus for visible light communication using the electrically switchable glass includes a reception unit for receiving a data signal, a control unit for generating current and voltage corresponding to the data signal and controlling the transmittance of the electrically switchable glass based on the current and the voltage, and a transmission unit for adjusting the brightness of visible light that passes through the glass based on the transmittance and performing visible light communication using the visible light that has passed through the glass.
Abstract:
A method and apparatus for controlling Zigbee wireless lighting are disclosed. The apparatus for controlling Zigbee wireless lighting includes an address management unit, a packet conversion unit, and a client unit. The address management unit detects a Zigbee wireless address, corresponding to a light ID included in a command received from a user terminal, in an address management table. The packet conversion unit converts the command into a Zigbee light link (ZLL)-based packet. The client unit transfers the ZLL-based packet to Zigbee wireless illumination light corresponding to the Zigbee wireless address in order to control the Zigbee wireless illumination light.
Abstract:
An apparatus and method for providing indoor location information are disclosed herein. The apparatus includes a signal reception unit, a global positioning system (GPS) data reception unit, a frame generation unit, a scheduling unit, and a signal transmission unit. The signal reception unit receives a lighting control frame from a lighting control device. The GPS data reception unit receives location data from GPS satellites. The frame generation unit generates a location data frame by extracting the location of an illumination light stored in a lighting arrangement storage unit, modifying the location data and adding a header to the modified location data. The scheduling unit schedules the lighting control frame or the location data frame. The signal transmission unit transfers the lighting control frame or the location data frame to the corresponding illumination light based on the results of the scheduling of the scheduling unit.
