Abstract:
The present invention relates to a method of processing a Digital Multiplex (DMX)-Visible Light Communication (VLC) address and a device using the method. In the method of processing a DMX-VLC address, a DMX-512 packet is received. It is determined whether the DMX-512 packet includes dimming data by using a start code of the DMX-512 packet. Lighting data is processed using an address recorded in a DMX-512 address field of a DMX-VLC address included in the DMX-512 packet if it is determined that the DMX-512 packet includes the dimming data. Non-lighting data is processed using an address recorded in a DMX-VLC extended address field of the DMX-VLC address if it is determined that the DMX-512 packet does not include dimming data.

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.
