When the packet transmission is completed, the first illuminator 41 can check whether the data (firmware) is transmitted without any damage or some data is damaged in the transmission process, and transmit the result to the terminal 100.

If some files are missing or damaged during transmission, the first illuminator 41 transmits a CRC check result to the terminal 100, and the terminal 100 can transmit the update data again.

Since the firmware updating process between the terminal 100 and the first illuminating device 41 has been described above, as described above, since the firmware updating of at least two or more lighting devices is performed at the same time, The first to third illuminating devices 41 to 43 can be performed simultaneously.

In such a case, the first illuminating device 41 may be a coordinator and the third illuminating device 43 may be a router.

Here, the way in which the firmware of all the lighting devices 41 to 43 is updated through the terminal 100 may be referred to as a centralized wireless data transmission method.

Alternatively, the terminal 100 and the illumination device having completed the firmware update may operate as coordinators, and the firmware of the remaining illumination devices may be updated through the terminal 100 and the specific illumination device, It can be referred to as a data transmission method.

As described above, in the lighting system 1 related to the first embodiment of the present invention, the firmware update of a large number of lighting devices 41 through 43 is performed through the distributed data transmission method, thereby reducing the network load.

Meanwhile, the firmware update process can be divided into a firmware file downloading step and a firmware file install step.

At this time, the step in which the specific lighting device can function as the coordinator is the step of completing the downloading of the firmware file. That is, a particular lighting device may transfer the firmware file to another lighting device upon completion of downloading the firmware file.

Also, the firmware file may be divided into a plurality of packets and transmitted. Accordingly, the firmware update of the third illuminating device 43 can be performed through the first illuminating device 41 and the second illuminating device 42. [

For example, some of the packets may be transmitted through the first illuminator 41 and the remaining packets may be transmitted through the second illuminator 42.

In this case as well, the third illuminator 43 performs a CRC check on the entire firmware file and transmits the result to the terminal 100, thereby improving the stability and reliability of the update.

Here, the lighting device in which the firmware update is performed may be variously determined based on the position of the corresponding node and the transmission voltage RSSI of each channel.

The magnitude of the transmission voltage of the corresponding channel may be an indicator for determining whether the node is physically separated by a certain distance or more.

In this case, when the firmware of the first and second illuminating devices 41 and 42 is updated through the first channel through the terminal 100, the first and / The firmware update of the third illuminating device 43 via the first and second illuminating devices 41 and 42 may be performed on the second channel.

Also, the second channel may be determined differently from the first channel.
