         [0046]      FIG. 9  illustrates an example of a data command to control a multi-zone of a lighting apparatus according to example embodiments and  FIG. 10  illustrates an example of forming a multi-zone using the lighting apparatus according to example embodiments. 
         [0047]    Referring to  FIG. 9 , a zone of a lighting device may be set based on the data format of  FIG. 7 , using the ‘Light Device Setting’ of the setting command of  FIG. 4 . In this example, a zone #1 is set for lighting devices #1 through #4, a zone #2 is set for lighting devices #5 through #8, a zone #3 is set for lighting devices #9 through #12, and a zone #4 is set for lighting devices #13 through #16, as illustrated in  FIG. 10 . 
         [0048]    A button of a switch  110  may be set based on the data format of  FIG. 8 , using ‘Switch Setting’ of the setting command of  FIG. 4 . 
         [0049]    Each switch  110  may control a corresponding lighting device, based on the ‘Zone Control’ of the setting command of  FIG. 6 . For example, when a button #1 of the switch  110  is pressed, ‘Zone Control’ is wirelessly transmitted to control each lighting device. In this example, data including ‘Zone Control’ may be broadcasted. 
         [0050]    For example, when a button #8 of the switch  110  is pressed, the lighting device # 1, the lighting device #2, the lighting device #3, and the lighting device #4 may be simultaneously controlled based on ‘Zone Control’. 
         [0051]    In this example, the lighting devices may be variously arranged, and a command from a starting device may be transmitted to a target device. 
         [0052]      FIGS. 11 through 13  illustrate an operation of transmitting data from a starting device to a target device in a lighting apparatus according to example embodiments. 
         [0053]    Referring to  FIG. 11 , each device may include a neighbor table, which preferentially stores, information associated with a radius of 1 hop and information associated with a radius of 2 hops, and may manage the information. Each device may determine, as a next hop, a device having a lowest cost, based on the neighbor table, when routing is performed. In this example, the cost may be calculated based primarily on a distance. 
         [0054]    Referring to  FIGS. 12 and 13 , each device may detect a new route to avoid bypassing a device that currently does not operate, and may transmit data. 
         [0055]    According to example embodiments, a multi-zone for a plurality of lighting devices connected to a wireless network may be formed and controlled and thus, a desired lighting device may be easily changed and controlled. 
         [0056]    Although embodiments have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined by the claims and their equivalents.
