  The control unit 40 controls so that at least one of the first switch 110 and the second switch 210 is conductive. Specifically, the control unit 40 controls so that only the first switch 110 is turned on by passing a current through the coil 112 of the first switch 110 and not passing a current through the coil 212 of the second switch 210. On the other hand, the control unit 40 controls the second switch 210 so that only the second switch 210 is conducted by passing a current through the coil 212 of the second switch 210 and not passing a current through the coil 112 of the first switch 110. Further, the control unit 40 controls the first switch 110 and the second switch 210 to be conductive by passing a current through the coil 112 of the first switch 110 and a current through the coil 212 of the second switch 210. In this specification, the state in which only the first switch 110 is conductive is the first conductive state, the state in which only the second switch 210 is conductive is the second conductive state, and the state in which the first switch 110 and the second switch 210 are conductive is the first. It may be described as 3 conduction state.

  The control unit 40 performs control so that at least one of the first switch 110 and the second switch 210 is conducted based on a predetermined switching operation. Specifically, when the control unit 40 detects that the time when the supply of power is temporarily stopped by the external switch 52 is within a predetermined time range, the first switch 110 and the second switch 210 are turned on in the first state. Switching between the conductive state, the second conductive state, and the third conductive state. In the first conduction state, the first switch 110 is conducted. In the second conduction state, the second switch 210 is conducted. In the third conduction state, the first switch 110 and the second switch 210 are conducted. Specifically, when the external switch 52 is switched from an on state to an off state and then switched to an on state within a predetermined time range, the control unit 40 includes the first switch 110 and the second switch 210. Is switched to one of the first conduction state, the second conduction state, and the third conduction state. In this specification, an operation in which the external switch 52 is switched from an on state to an off state and switched to an on state within a predetermined time range may be referred to as a pullless operation. The predetermined time is, for example, 1.5 seconds or less. In this embodiment, every time a pullless operation (predetermined switching operation) is performed, the conduction state of the first switch 110 and the second switch 210 is repeatedly switched in the order of the first conduction state, the second conduction state, and the third conduction state. .

  For example, when the lighting apparatus 10 is in the first conduction state, the pullless operation is performed, so that the control unit 40 changes the conduction state of the first switch 110 and the second switch 210 from the first conduction state to the second conduction state. Switch. Specifically, when the lighting apparatus 10 is in the first conduction state, the control unit 40 causes a current to flow through the coil 212 of the second switch 210 by performing a pullless operation. Further, the control unit 40 controls the conduction state of the first switch 110 and the second switch 210 so that only the second switch 210 is conducted by not passing a current through the coil 112 of the first switch 110.

  On the other hand, when the lighting apparatus 10 is in the second conduction state, the pullless operation is performed, so that the control unit 40 changes the conduction state of the first switch 110 and the second switch 210 from the second conduction state to the third conduction state. Switch. Specifically, when the lighting fixture 10 is in the second conduction state, the control unit 40 causes a current to flow through the coil 112 of the first switch 110 by performing a pullless operation. Further, the control unit 40 controls the conduction state of the first switch 110 and the second switch 210 so that the first switch 110 and the second switch 210 are conducted by passing a current through the coil 212 of the second switch 210. .

  Further, when the lighting apparatus 10 is in the third conduction state, the pullless operation is performed, so that the control unit 40 changes the conduction state of the first switch 110 and the second switch 210 from the third conduction state to the first conduction state. Switch. Specifically, when the lighting fixture 10 is in the third conduction state, the control unit 40 causes a current to flow through the coil 112 of the first switch 110 by performing a pullless operation. Further, the control unit 40 controls the conduction state of the first switch 110 and the second switch 210 so that only the first switch 110 is conducted by not passing a current through the coil 212 of the second switch 210.

  When the power is turned on, that is, when the lighting fixture 10 is switched from the off state to the on state, the control unit 40 makes at least one of the first switch 110 and the second switch 210 conductive based on the activation information stored in the storage unit 42. Thus, the conduction state of the first switch 110 and the second switch 210 is controlled. Whether to start the conduction state of the first switch 110 and the second switch 210 in the first conduction state, the second conduction state, or the third conduction state when the power is turned on may be set in advance as activation information, It is also possible to store the conduction state at the time of the previous light-off as the activation information and start with the conduction state at the time of the previous light-off.

  Thus, every time the pullless operation is performed, the control unit 40 switches between the first conduction state, the second conduction state, and the third conduction state. Therefore, the light color which the lighting fixture 10 lights can be selected from three patterns.

  As described above with reference to FIG. 1, the first light source 130 is lit with a light amount based on the current supplied from the first DC power supply 126. The second light source 230 is lit with a light amount based on the current supplied from the second DC power supply 226. Thus, since the lighting fixture 10 has an electric power supply part for every light source, it can supply the electric power corresponding to each light source. Therefore, in the lighting fixture 10 of this embodiment, since two types of light sources with different rated power (operating power) can be mounted, the variation of lighting fixtures spreads. For example, the first light source 130 may be an LED, and the second light source 230 may be an organic EL element (OLED (Organic Light Emitting Diode)).

  Further, the control unit 40 changes the conduction state of the first switch 110 and the second switch 210 in the order of the first conduction state, the second conduction state, and the third conduction state each time a predetermined switching operation (pre-press operation) is performed. Switch repeatedly. Therefore, the lighting states of the three patterns can be easily switched.

[Embodiment 2]
With reference to FIG. 2, the lighting fixture 10 which concerns on Embodiment 2 of this invention is demonstrated. FIG. 2 is a block diagram of the luminaire 10 according to Embodiment 2 of the present invention. Except for the point that the second light source 230 is a light source that is driven by alternating current power, the second light source 230 has the same configuration as that of the lighting fixture 10 according to the second embodiment, and therefore, the description of overlapping portions is omitted.

  The lighting fixture 10 includes a first switch 110, a second switch 210, a first power supply unit 120, a second power supply unit 220, a first light source 130, a second light source 230, and a control unit 40. Prepare. The second power supply unit 220 includes a wiring n1 and a wiring n2.

  In the present embodiment, the first light source 130 is an LED module that is driven by DC power. The second light source 230 is an LED bulb that is driven by AC power. The LED bulb incorporates a power supply circuit that converts AC power into DC power and an LED element that lights when DC power is supplied from the power supply circuit. The second switch 210 is connected to the second light source 230 via the wiring n1. The second light source 230 is connected to the AC power supply 54 via the wiring n2. The second power supply unit 220 is a socket in which an LED lamp can be mounted, for example. The wiring n1 and the wiring n2 are, for example, a wiring and a base provided in a socket.

  When the first switch 110 is turned on, DC power is supplied to the first light source 130. The DC power is generated by converting the AC power from the AC power supply 54 by the first power supply unit 120. When the second switch 210 is turned on, AC power from the AC power supply 54 is supplied to the second light source 230 via the wiring n1 and the wiring n2.

  As described above with reference to FIG. 2, the lighting fixture 10 includes the first switch 110 in the preceding stage of the first power supply unit 120. In addition, the lighting fixture 10 includes a second switch 210 in front of the second power supply unit 220. Therefore, electric power corresponding to each light source can be supplied. Therefore, the lighting fixture 10 can turn on two different types of light sources, and the variation of the lighting fixture is widened. Further, by making the second light source 230 a light source that can be easily exchanged, such as an LED bulb, the luminance, correlated color temperature, light distribution angle, and the like can be easily changed simply by exchanging the light source.

[Embodiment 3]
With reference to FIG. 3, the lighting fixture 10 which concerns on Embodiment 3 of this invention is demonstrated. FIG. 3 is a block diagram of the luminaire 10 according to Embodiment 3 of the present invention. Since it has the structure similar to the lighting fixture 10 which concerns on Embodiment 1 except the point which the lighting fixture 10 further equips with the receiving part 50, description is abbreviate | omitted about an overlapping part.

  The lighting fixture 10 includes a first switch 110, a second switch 210, a first power supply unit 120, a second power supply unit 220, a first light source 130, a second light source 230, a control unit 40, A receiving unit 50.

  The receiving unit 50 receives the lighting state switching signal from the remote controller 56. In the present embodiment, the receiving unit 50 and the remote controller 56 can perform wireless communication via infrared rays or radio waves. The receiving unit 50 is electrically connected to the control unit 40. Specifically, when an operation indicating a change in lighting state is performed in the remote controller 56, a lighting state switching signal is transmitted from the remote controller 56. When the receiving unit 50 receives the lighting state switching signal, the lighting state switching signal is output to the control unit 40. The control unit 40 determines whether a switching operation has been performed based on the lighting state switching signal. When it is determined that the switching operation has been performed, the control unit 40 switches the conduction state of the first switch 110 and the second switch 210 in the order of the first conduction state, the second conduction state, and the third conduction state.

  As described above with reference to FIG. 3, the lighting fixture 10 further includes the receiving unit 50. Therefore, the lighting state can be easily switched by operating the remote controller 56.

[Embodiment 4]
With reference to FIG. 1 and FIG. 4, the illumination system 300 which concerns on Embodiment 4 of this invention is demonstrated. FIG. 4 is a block diagram of an illumination system 300 according to Embodiment 4 of the present invention. The 1st lighting fixture 10a, the 2nd lighting fixture 10b, and the 3rd lighting fixture 10c have the structure similar to the lighting fixture 10 which concerns on Embodiment 1. FIG.

  The lighting system 300 includes a first lighting fixture 10a, a second lighting fixture 10b, a third lighting fixture 10c, and an external switch 52. Each of the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c includes a first switch 110, a second switch 210, a first power supply unit 120, a second power supply unit 220, and a second switch. 1 light source 130, 2nd light source 230, and the control part 40 are provided (refer FIG. 1).

  The first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c are connected in parallel to the AC power supply 54 and the external switch 52. By performing the pullless operation of the external switch 52, the lighting states of the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c can be switched simultaneously. As a normal usage pattern, the lighting states of the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c are all the same. For example, when the first light fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c are all in the first conduction state and the first light source 130 is turned on in the initial state, The 1 lighting fixture 10a, the 2nd lighting fixture 10b, and the 3rd lighting fixture 10c are all switched to the 2nd conduction | electrical_connection state, and the 2nd light source 230 lights. Similarly, when switching from the second conduction state to the third conduction state by the pullless operation, when switching from the third conduction state to the first conduction state, the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c are similarly configured. All the lighting states are switched at the same time. Thereby, the lighting state of the 1st lighting fixture 10a, the 2nd lighting fixture 10b, and the 3rd lighting fixture 10c installed, for example in one living room can be switched simultaneously by the pullless operation of the one external switch 52. FIG.

  Here, there may be variations in the detection accuracy of the pullless operation in the control unit 40 provided in each of the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c. That is, in the control unit 40, there may be variations in the detection accuracy of the time when the supply of power is temporarily stopped by the external switch 52. For example, when the time from when the external switch 52 is turned off to when the external switch 52 is turned on (off-on time) is 1 second, the control unit 40 of the first lighting fixture 10a determines that the pullless operation has been performed, and the first switch 110 Although the control unit 40 of the second lighting fixture 10b does not determine that the pullless operation has been performed, the first switch 110 and the second switch 210 may not be controlled. This is because the detection accuracy of the off-on time of the control unit 40 of each lighting fixture varies. Accordingly, the first lighting fixture 10a is switched from the first conduction state to the second conduction state, the second light source 230 is turned on, and the first light source 130 is turned on while the second lighting fixture 10b remains in the first conduction state. . That is, a mismatch occurs in the lighting state of the lighting fixture.

  If there is a discrepancy in the lighting status of the lighting fixtures, the subsequent pullless operation will switch the lighting status of each lighting fixture in order while maintaining the discrepancy in lighting status, so the original lighting status (all lighting fixtures are the same) It is extremely difficult to return to the lighting state. Further, even when all the lighting fixtures are turned off by turning off the external switch 52, the storage unit 42 of each lighting fixture stores the conduction state immediately before turning off, so that the external switch 52 is turned on next time. The lighting state of remains inconsistent.

  When such a mismatch in the lighting state of the lighting fixtures occurs, the lighting state of the lighting system 300 needs to be initialized. The control unit 40 of the present embodiment has an initialization function. “Initialization” refers to matching the conduction states of the first switch 110 and the second switch 210 included in each lighting fixture connected to the external switch 52.

  The initialization of the lighting state of the illumination system 300 will be described with reference to FIGS. 1, 4, 5, and 6 (a). FIG. 5 is a flowchart showing an initialization method of the illumination system 300 according to Embodiment 4 of the present invention. 6A and 6B are time charts showing the input voltage of the illumination system 300. FIG.

  In the lighting system 300, it is preferable that the lighting state of the 1st lighting fixture 10a, the 2nd lighting fixture 10b, and the 3rd lighting fixture 10c can be initialized. Each control part 40 of the 1st lighting fixture 10a, the 2nd lighting fixture 10b, and the 3rd lighting fixture 10c has the memory | storage part 42. FIG. The memory | storage part 42 memorize | stores the starting information which shows the lighting state at the time of starting. The control unit 40 counts the number of pullless operations (the number of switching operations) indicating the number of pullless operations (switching operations). The control unit 40 includes a timer, and measures an external switch conduction time T1 indicating a time during which the external switch 52 is conductive after the pullless operation is performed. When the control unit 40 determines that the external switch conduction time T1 is within the continuous determination period and the pullless operation has been performed, the control unit 40 increases the count value of the number of pullless times by one. The control unit 40 determines whether or not an initialization operation has been performed based on whether or not the number of pullless times is equal to or greater than a predetermined number of consecutive times. When it is determined that the initialization operation has been performed, the control unit 40 performs control so that at least one of the first switch 110 and the second switch 210 is turned on based on the activation information stored in the storage unit 42. That is, when it is determined that the initialization operation has been performed, the control unit 40 performs control so that a predetermined lighting state is obtained.

  The initialization of the lighting state of the illumination system 300 has been described above. Hereinafter, a method for initializing the lighting state of the illumination system 300 will be described with reference to FIGS. 1, 4, and 5. FIG. 5 is a flowchart showing an initialization method of the illumination system 300 according to Embodiment 4 of the present invention. The illumination system 300 is initialized by executing the processing of step S102 to step S122.

  Step S102: The control unit 40 determines whether or not a pullless operation has been performed. Specifically, within a predetermined time after the external switch 52 is operated from conduction (ON) to non-conduction (OFF), the external switch 52 is operated and the external switch 52 is switched from non-conduction (OFF) to conduction (ON). It is determined whether or not it can be switched to. When the control unit 40 determines that a pullless operation has been performed (step S102: YES), the process proceeds to step S104. When the control unit 40 determines that the pullless operation has not been performed (step S102: NO), the process returns to step S102 again, and the process of step S102 is repeated until the pullless operation is performed.

  Step S104: The timer of the control unit 40 starts timing. The process proceeds to step S106.

  Step S106: The control unit 40 increases the count value n of the number of pullless times by one, and the count value n of the number of pullless times becomes “1 time”. The process proceeds to step S108.

  Step S108: The control unit 40 determines whether or not the continuous determination period T has elapsed since the pullless operation was performed. Specifically, the control unit 40 compares the external switch conduction time T1 and the continuous determination period T, and determines whether or not the external switch conduction time T1 exceeds the continuous determination period T. When the control unit 40 determines that the continuous determination period T has elapsed since the pullless operation was performed (step S108: YES), the process proceeds to step S112. When the control unit 40 determines that the continuous determination period T has not elapsed since the pullless operation was performed (step S108: NO), the process proceeds to step S110.

  Step S110: The control unit 40 determines that a pullless operation has been performed. The process proceeds to step S114.

  Step S112: The control unit 40 resets the timer. That is, the timekeeping time is set to “0”. In addition, the control unit 40 resets the count of the number of pullless times. That is, the control unit 40 sets the count of the number of pullless times to “0”. The process returns to step S102.

  Step S114: The control unit 40 resets the timer. That is, the timer time is set to “0”. The process proceeds to step S116.

  Step S116: The timer starts counting from the timing time 0 again. The process proceeds to step S118.

  Step S118: The control unit 40 counts up the number of pullless times. That is, the control unit 40 increases the count value n of the number of pullless times by 1, and the count value n of the number of pullless times changes from “n times” to “n + 1 times”. The process proceeds to step S120.

  Step S120: The control unit 40 compares the count value n of the pullless count with a predetermined continuous count, and determines whether or not the count value n of the pullless count is equal to or greater than the predetermined continuous count. Here, the predetermined number of consecutive times is “5 times”. The control unit 40 determines whether or not the count value n of the number of pullless times is 5 or more. When the control unit 40 determines that the count value n of the number of pullless times is not equal to or greater than the predetermined continuous number (step S120: NO), the process returns to step S108. If the control unit 40 determines that the count value n of the number of pullless times is equal to or greater than a predetermined number of consecutive times (step S120: YES), the process proceeds to step S122.

  Step S122: When the control unit 40 determines that the count value n of the number of pullless times is equal to or greater than a predetermined continuous number (step S120: YES), the control unit 40 performs initialization. Specifically, the control unit 40 controls based on the activation information so that only the first switch 110 is turned on, and controls only the first light source 130 to be lit. Accordingly, since the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c all include the control unit 40 having the same initialization function, the first lighting fixture 10a, the second lighting fixture 10b, and In all of the third lighting fixtures 10c, only the first light source 130 is lit. That is, the lighting state of the 1st lighting fixture 10a, the 2nd lighting fixture 10b, and the 3rd lighting fixture 10c corresponds. In addition, when the control unit 40 determines that the count value n of the number of pullless times is equal to or greater than a predetermined continuous number (step S120: YES), the control unit 40 resets the count value of the number of pullless times to “0”. To do. Further, the control unit 40 resets the count value of the timer to “0”. The process returns to step S102.

  The method for initializing the lighting state of the lighting system 300 has been described above. Hereinafter, an example of initialization of the lighting state of the illumination system 300 will be described with reference to FIGS. 5 and 6A. FIG. 6A is a time chart showing input voltages of the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c of the lighting system 300. FIG.

  In this embodiment, the time (predetermined time) for determining whether or not a pullless operation has been performed is 1.5 seconds as an example. The predetermined number of consecutive times is 5 times as an example. The continuous determination period T is 3 seconds as an example. The activation information indicates a lighting state in which only the first light source 130 is lit. The setting of the predetermined number of continuous times and the continuous determination period T is stored in the storage unit 42, for example. The control unit 40 includes a timer, and measures an external switch conduction time T1 indicating a time during which the external switch 52 is conductive after the pullless operation is performed.

  The times from time t1 to t2, time t3 to time t4, time t5 to time t6, time t7 to time t8, and time t9 to time t10 are each 1 second, for example. The external switch conduction time T1 from time t2 to time t3, time t4 to time t5, time t6 to time t7, and time t8 to time t9 is, for example, 2 seconds.

  At time t1, when the external switch 52 is operated and the external switch 52 is switched from conduction (ON) to non-conduction (OFF), the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture are switched from the AC power source 54. AC power to 10c is cut off.

  At time t2, when the external switch 52 is operated and the external switch 52 is switched from non-conductive (OFF) to conductive (ON) within a predetermined time from the time t1 (that is, within 1.5 seconds from the time t1), the control is performed. The unit 40 determines that a pullless operation has been performed (step S102 in FIG. 5: YES). When the control unit 40 determines that the pullless operation has been performed, the timer of the control unit 40 starts measuring time (step S104 in FIG. 5). Further, the control unit 40 increases the count value of the number of pullless times by one, and the count value of the number of pullless times becomes “1 time” (step S106 in FIG. 5).

  From time t3 to time t4, similarly to time t1 to time t2, the control unit 40 determines that a pullless operation has been performed (step S110 in FIG. 5). The external switch conduction time T1, that is, the time from time t2 to time t3 is 2 seconds, and is within 3 seconds of the continuous determination period T. Therefore, at time t4, the control unit 40 increases the count value of the number of pullless times by one, and the count value of the number of pullless times becomes “twice” (step S118 in FIG. 5).

  Similarly to the time t3 to the time t4, the pullless operation (step S110 in FIG. 5) is performed within 3 seconds of the continuous determination period T at the time t5 to the time t6, the time t7 to the time t8, and the time t9 to the time t10. Therefore, the count value of the number of pullless times is counted as “3 times” at time t6, “4 times” at time t8, and “5 times” at time t10 (step S118 in FIG. 5).

  At time t10, the count value of the number of pullless times becomes “5 times”. Therefore, since the count value of the number of pullless times is equal to or greater than a predetermined number of consecutive times, the control unit 40 determines that an initialization operation has been performed (step S120 in FIG. 5: YES).

  When it is determined that the initialization operation has been performed (step S120 in FIG. 5: YES), the control unit 40 performs control so that only the first switch 110 is turned on based on the activation information, and only the first light source 130 is present. Control to light up. Accordingly, since the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c all include the control unit 40 having the same initialization function, the first lighting fixture 10a, the second lighting fixture 10b, and In all of the third lighting fixtures 10c, only the first light source 130 is lit. That is, the lighting state of the 1st lighting fixture 10a, the 2nd lighting fixture 10b, and the 3rd lighting fixture 10c corresponds. When the control unit 40 determines that the initialization operation has been performed (step S120 in FIG. 5: YES), the control unit 40 resets the count value of the number of pullless times to “0”.

  As described above with reference to FIGS. 1, 4, 5, and 6 (a), in the lighting system 300, when the control unit 40 determines that the initialization operation has been performed, the control unit 40 stores the information in the storage unit 42. Based on the stored activation information, control is performed so that at least one of the first switch 110 and the second switch 210 is conducted. That is, when it is determined that the initialization operation has been performed, the control unit 40 performs control so that a predetermined lighting state is obtained. Therefore, even if the lighting states of the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c are different, the first lighting fixture 10a and the second lighting fixture 10b can be performed by performing the initialization operation. And the lighting state of all the 3rd lighting fixtures 10c can be match | combined.

  A modification of the initialization of the lighting state of the illumination system 300 will be described. In the lighting system 300, each control part 40 of the 1st lighting fixture 10a, the 2nd lighting fixture 10b, and the 3rd lighting fixture 10c has the memory | storage part 42. FIG. The memory | storage part 42 memorize | stores the starting information which shows the lighting state at the time of starting. The controller 40 determines whether or not the initialization operation has been performed based on whether or not the switching of the external switch 52 from non-conduction to conduction is performed a predetermined number of times within the initialization determination period. When it is determined that the initialization operation has been performed, the control unit 40 performs control so that at least one of the first switch 110 and the second switch 210 is turned on based on the activation information stored in the storage unit 42. That is, when it is determined that the initialization operation has been performed, the control unit 40 performs control so that a predetermined lighting state is obtained. In the activation information stored in the storage unit 42 of each luminaire, the switches that are connected at the time of activation are all set to the same switch. Therefore, the switches that are turned on when the luminaires are activated are all the same in each luminaire.

  In the above, the modification of initialization of the lighting state of the illumination system 300 has been described. Hereinafter, with reference to FIG.6 (b), the modification of initialization of the lighting state of the illumination system 300 is demonstrated concretely. FIG. 6B is a time chart showing input voltages of the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c of the lighting system 300.

  In the present embodiment, the predetermined number of times is five as an example. The initialization determination period T2 is 15 seconds as an example. The activation information indicates a lighting state in which only the first light source 130 is lit. The setting of the predetermined number of times and the initialization determination period T2 is stored in the storage unit 42, for example. The control unit 40 includes a timer and measures an elapsed time after the external switch 52 is switched from conduction (ON) to non-conduction (OFF).

  At time t1, when the external switch 52 is operated and the external switch 52 is switched from conduction (ON) to non-conduction (OFF), the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture are switched from the AC power source 54. AC power to 10c is cut off.

  When the external switch 52 is operated at time t2 to switch the external switch 52 from non-conduction (OFF) to conduction (ON), the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c are switched from the AC power source 54. AC power is supplied.

  Similarly to time t1, at time t3, time t5, time t7, and time t9, when the external switch 52 is operated and the external switch 52 is switched from conduction (ON) to non-conduction (OFF), the AC power supply 54 AC power to the 1 lighting fixture 10a, the 2nd lighting fixture 10b, and the 3rd lighting fixture 10c is interrupted | blocked.

  Similarly to time t2, when the external switch 52 is operated and the external switch 52 is switched from non-conductive (OFF) to conductive (ON) at time t4, time t6, time t8, and time t10, the AC power supply 54 AC power is supplied to the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c.

  The initialization determination period T2 starts from time t1. In the initialization determination period T2 (that is, for 15 seconds) from time t1 to time t11, the control unit 40 switches the external switch 52 from non-conductive to conductive for a predetermined number of times (that is, five times). Determine whether or not. Since switching of the external switch 52 from non-conduction to conduction is performed a total of five times at time t2, time t4, time t6, time t8 and time t10, the control unit 40 determines that the initialization operation has been performed. .

  When it is determined that the initialization operation has been performed, the control unit 40 performs control so that only the first switch 110 is turned on and controls only the first light source 130 to be lit based on the activation information. Accordingly, since the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c all include the control unit 40 having the same initialization function, the first lighting fixture 10a, the second lighting fixture 10b, and In all of the third lighting fixtures 10c, only the first light source 130 is lit. That is, the lighting state of the 1st lighting fixture 10a, the 2nd lighting fixture 10b, and the 3rd lighting fixture 10c corresponds.

  On the other hand, the control unit 40 initializes when the external switch 52 is not switched from non-conduction to conduction in the initialization determination period T2 (that is, for 15 seconds) a predetermined number of times (that is, five times). The timer is reset when the initialization determination period T2 elapses. In the control unit 40, after the timer reset, the timer starts measuring time from the timing of the next switching operation of the external switch 52 from conduction to non-conduction.

  As described above with reference to FIGS. 1, 4, and 6 (b), in the lighting system 300, the control unit 40 is stored in the storage unit 42 when it is determined that the initialization operation has been performed. Based on the activation information, control is performed so that at least one of the first switch 110 and the second switch 210 is conducted. Therefore, even if the lighting states of the first lighting fixture 10a, the second lighting fixture 10b, and the third lighting fixture 10c are different, the first lighting fixture 10a and the second lighting fixture 10b can be performed by performing the initialization operation. And the lighting state of all the 3rd lighting fixtures 10c can be match | combined.
