- step S26 determines whether the pairing flag notification signal has been received from lamp A, which is the parent device (step S26: Yes). If it is determined in step S26 that the pairing flag notification signal has been received from lamp A, which is the parent device (step S26: Yes), wireless circuit 50 belongs to the same group as lamp A as the slave device. Is set to “1” (step S27).
- the radio circuit 50 inputs a dimming lighting instruction signal for instructing the driver circuit 30 to perform 50% dimming lighting (step S28).
- the driver circuit 30 reduces the duty ratio of the control signal input to the power conversion circuit 20. Thereby, the electric power input from the power conversion circuit 20 to the light emitting module 40 decreases, and the amount of light emitted from the light emitting module 40 decreases.
- the radio circuit 50 determines whether or not a group confirmation signal has been received from the lamp A, which is the parent device (step S29).
- step S29 If it is determined in step S29 that the group confirmation signal has not been received from lamp A as the parent device (step S29: No), radio circuit 50 has received a time-up notification signal from lamp A as the parent device. It is determined whether or not (step S31).
- step S31 If it is determined in step S31 that the time-up notification signal has not been received from the lamp A that is the parent device (step S31: No), the radio circuit 50 proceeds to the process of step S28 again.
- step S31 determines whether the time-up notification signal has been received from the lamp A, which is the master unit (step S31: Yes). If it is determined in step S31 that the time-up notification signal has been received from the lamp A, which is the master unit (step S31: Yes), the radio circuit 50 ends the process as it is.
- step S29 If it is determined in step S29 that the group determination signal has been received from lamp A, which is the parent device (step S29: Yes), radio circuit 50 inputs a blink instruction signal that instructs driver circuit 30 to blink. (Step S30). At this time, when the blinking instruction signal is input from the wireless circuit 50, the driver circuit 30 changes the duty ratio of the control signal input to the power conversion circuit 20 at a constant period. Thereby, the electric power input from the power conversion circuit 20 to the light emitting module 40 changes at a constant cycle, so that the amount of light emitted from the light emitting module 40 also changes at a constant cycle, and the lamps B and C blink. Thereafter, the process proceeds to step S31.
- the radio circuit 50 broadcasts a beacon signal (step S51).
- the wireless circuit 50 receives a first ACK signal transmitted from a wireless LAN access point or the like belonging to the same network as the lamp A provided with the wireless circuit 50 (step S52).
- a wireless LAN access point or the like belonging to the same network as the lamp A provided with the wireless circuit 50.
- all other PAN-IDs that can be received by the radio circuit 50 are received.
- the radio circuit 50 detects an empty PAN-ID to be given to the lamp A (step S53). That is, select a PAN-ID that is not used by another device.
- the radio circuit 50 sets the pairing flag stored in the RAM 55 to “0” (step S41). This pairing flag indicates whether or not there is a lamp connected to the same wall switch as the own machine.
- the radio circuit 50 obtains its own PAN-ID, Net-ID of lamps B and C and Net-ID of lamp D, which are stored in the RAM 55 (step S42), and The timer count value of the machine and the timer count values of the lamps B, C and D as the slave units are acquired (step S43).
- the radio circuit 50 calculates a difference ⁇ T between the timer count value of its own device and the timer count values of the lamps B, C, and D that are slave units (step S44).
- the radio circuit 50 determines whether or not the difference ⁇ T is within a preset range ( ⁇ T1 ⁇ T ⁇ T2) (step S45).
- this range may be set to ⁇ 1.0 sec ⁇ T ⁇ 1.0 sec. Since the timer count varies depending on the accuracy of the CPUs 54 and 254, it is desirable that the timer count is within a range commensurate with the accuracy capability of the CPU.
- step S45 If it is determined in step S45 that the difference ⁇ T is within the preset range (step S45: Yes), the radio circuit 50 determines the lamps (in this case, lamps B and C) to which the PAN-ID is assigned. The Net-ID is specified (step S46), and the pairing flag F1 is set to “1” (step S47).
- step S48 it is determined whether or not the determination of the difference ⁇ T has been completed for all the lamps.
- step S45 when it is determined in step S45 that the difference ⁇ T is not within the preset range (step S45: No), the radio circuit 50 performs the process of step S48 as it is.
- step S48 If it is determined in step S48 that the determination of the difference ⁇ T has been completed for all the lamps B, C, and D (step S48: Yes), the radio circuit 50 ends the time comparison process.
- step S48 determines that the determination of the difference ⁇ T has not been completed for all the lamps 1 (step S48: No). If it is determined in step S48 that the determination of the difference ⁇ T has not been completed for all the lamps 1 (step S48: No), the radio circuit 50 proceeds to the process of step S44 again.
- each lamp A, B, and C measures the elapsed time since its own device was turned on by wall switch X, and the time measured by the time measuring means.
- a specifying unit that specifies a plurality of lamps A, B, and C wired to the wall switch X based on time, and a plurality of lamps A and B that are specified to be connected to the same wall switch X by the specifying unit
- a wireless circuit 50 is provided for realizing PAN-ID providing means for assigning the same PAN-ID to B and C and registration means for registering the Net-ID of the remote control device.
- the lamps A, B, and C that are wired to the wall switch X and turned on at the same timing are identified only by turning on the wall switch X, and the same PAN-ID is assigned to all the identified lamps A, B, and C. Since the remote controller P can register the PAN-ID commonly assigned to all the lamps A, B, and C wired to the same wall switch X, it can be wired to the same wall switch X. There is no need to assign IDs individually to the plurality of connected lamps A, B, and C. Therefore, it is possible to facilitate the work of assigning IDs to the lamps A, B, and C wired to the same wall switch X.

壁スイッチ3は、図1に示すように、スイッチハンドル3aと、スイッチハンドル3aの外周部に配設されたハンドルプレート3bと、壁に取着され、スイッチハンドル3aおよびハンドルプレート3bを保持する本体部(図示せず)とを備える。そして、ユーザが、ハンドル3aの一部(図1の「オン」、「オフ」と表示された部位)を押下すると、壁スイッチ3のオンオフ状態が切り替わる。ユーザがスイッチハンドル3aの一部(図1の「オン」と表示された部位)を押下すると、壁スイッチ3に有線接続された複数のランプ1全てに電力が供給され、複数のランプ1全てが点灯する。続いて、ユーザがスイッチハンドル3aの一部(図1の「オフ」と表示された部位)を押下すると、壁スイッチ3に有線接続された複数のランプ1全てへの電力供給が遮断され、複数のランプ1全てが消灯する。
<2-1>全体動作
本実施の形態に係る照明システムは、1つの壁スイッチ3に有線接続された複数のランプ1に識別情報として同一のPAN-IDを付与するものである。即ち、同一の壁スイッチ3に有線接続された複数のランプ1からなるグループを他の壁スイッチに有線接続された電気機器と区別するために、同一の壁スイッチ3に有線接続された複数のランプ1に同一のPAN-IDを付与する。これにより、同一の壁スイッチ3に有線接続された複数のランプが同一のPAN-IDでグループ化されることになる。この複数のランプ1は、工場出荷時に製品固有のNet-IDが付与されているが、リモコン2との無線通信に使用するPAN-IDは付与されていない。また、Net-IDは、各製品毎に異なる番号からなるものであり、製品が異なれば必ずNet-IDも異なることになる。
照明システム1000の一部を構成するランプA,B,Cのうち、親機となるランプAの無線回路50の動作について図8に基づいて説明する。ここで、無線回路50の各動作は、CPU54がROM56に予め記憶されているプログラムをRAM55に読み出した後、当該プログラムを実行することにより実現される。
照明システム1000の一部を構成するランプA,B,C,Dのうち、子機となるランプB,Cの無線回路50の動作について図9に基づいて説明する。ここで、無線回路50の各動作は、CPU54がROM56に予め記憶されているプログラムをRAM55に読み出した後、当該プログラムを実行することにより実現される。
次に、無線回路50による空きPAN-IDを検索する動作について図10に基づいて説明する。
<2-5>親機であるランプの無線回路の時間比較処理の動作
次に、親機であるランプ1の無線回路50が行う時間比較処理の動作について図11に基づいて説明する。
<変形例>
(1)実施の形態では、壁スイッチ3がオフからオンに切り替わる毎に、各ランプにPAN-IDを付与する処理を行う例について説明したが、これに限定されるものではない。例えば、各ランプ1が壁スイッチ3がオフからオンに切り替わったときに、自機に付与されたPAN-IDをROM56に記憶させるとともに、リモコン2もランプ1に付与されたPAN-IDをROM256に記憶させ、以後、壁スイッチ3がオフからオンに切り替わっても各ランプ1にPAN-IDを付与する処理を行わないようにしてもよい。
