Here, the setting data is data corresponding to the specifications of the light source module 2. The setting circuit 22 transmits a setting signal to the power supply device 1 at the time of start-up in which the operation is started by the drive voltage V10. Further, the setting circuit 22 may periodically transmit the setting signal to the power supply device 1 while operating with the drive voltage V10.

The DIP switch 221 of FIG. 2 is a switch having three-pole contacts, and the contacts of each pole are set to either on (conduction) or off (interruption) according to the state of each operation unit of three poles. .. The first end of each of the three resistors 222, 223, 224 is electrically connected to the low potential of the drive voltage V10 via the contact of each pole. The second end of each of the three resistors 222, 223, 224 is electrically connected to the high potential of the drive voltage V10. Therefore, assuming that the voltages across the contacts of the DIP switch 221 are set voltages V21, V22, and V23, the values of the set voltages V21, V22, and V23 are the values of the drive voltage V10 (H level) depending on the state of the contacts. Or it becomes 0V (L level). The combination of the values of the set voltages V21, V22, and V23 is switched by operating the operation unit of the DIP switch 221. Therefore, by setting the setting of the DIP switch 221 so as to correspond to the specifications of the light source module 2, the combination of the values of the set voltages V21, V22, and V23 becomes a combination corresponding to the specifications of the light source module 2. The number of poles of the DIP switch 221 is not limited to 3 and may be 1 pole, 2 poles, or 4 poles or more.

The integrated circuit 225 is a communication IC (Integrated Circuit) that performs two-wire wired communication, and performs serial communication with the arithmetic circuit 131, for example. The integrated circuit 225 generates setting data corresponding to the combination of the values of the setting voltages V21, V22, and V23. Then, the integrated circuit 225 transmits the setting signal including the setting data from the pair of communication ports. That is, the integrated circuit 225 transmits a setting signal including setting data corresponding to (specification of) the light source module 2. The pair of communication ports of the integrated circuit 225 are connected to the pair of communication paths W3 and W4, respectively. The pair of communication paths W3 and W4 are pulled up to the drive voltage V10 via resistors 226 and 227, respectively.

The control voltage V20 is a voltage generated from the input or output of the DC power supply 11 by a control power supply (not shown) included in the power supply device 1.

Upon receiving the setting signal, the arithmetic circuit 131 performs a rewriting process of rewriting at least a part of the control data in the memory 132 based on the setting data included in the setting signal. The arithmetic circuit 131 performs rewriting processing by performing arithmetic processing on the control data stored in the memory 132 and the setting data included in the received setting signal before receiving the setting signal.

(Rewriting process of setting data)
The process of rewriting the setting data will be described below.

(1) The setting data preferably includes information regarding the value of the load current Io supplied from the power supply circuit 12 to the light source 21. The arithmetic circuit 131 performs the rewriting process based on the information regarding the value of the load current Io included in the setting data.

For example, it is assumed that the light source module 2 combined with the power supply device 1 is replaced with the light source module 2 of the first specification (hereinafter referred to as the light source module 201) to the light source module 2 of the second specification (hereinafter referred to as the light source module 202). (See FIG. 1). According to the specifications of the light source module 201, the target value of the load current Io is Io1. According to the specifications of the light source module 202, the target value of the load current Io is Io2. In this case, in the replaced light source module 202, the setting circuit 22 generates setting data for setting the target value of the load current Io to Io2, and transmits the setting signal including this setting data to the arithmetic circuit 131. The arithmetic circuit 131 rewrites the data regarding the target value of the load current Io among the control data (control program and control parameters) stored in the memory 132 based on the setting data. That is, in the control data stored in the memory 132, the target value of the load current Io is changed from Io1 to Io2.

The operation of the power supply device 1 before and after the light source module 2 is replaced with the light source module 201 from the light source module 202 will be described with reference to FIG. The upper part of FIG. 3 shows the waveform of the PWM signal Y1 output from the arithmetic circuit 131 to the power supply circuit 12. The lower part of FIG. 3 shows the waveform of the load current Io. The arithmetic circuit 131 sets the on-duty of the PWM signal Y1 according to the dimming level. The higher the dimming level (that is, the larger the light output), the larger the on-duty of the PWM signal Y1. The lower the dimming level (that is, the smaller the light output), the smaller the on-duty of the PWM signal Y1. The power supply circuit 12 reads the on-duty of the PWM signal Y1 and adjusts the load current Io according to the on-duty. The power supply circuit 12 increases the value of the load current Io as the on-duty increases. The power supply circuit 12 reduces the value of the load current Io as the on-duty is smaller.

In FIG. 3, the light source module 201 is combined with the power supply device 1 from time t0 to time t1. Then, the light source module 201 is removed from the power supply device 1 at time t1, and the light source module 202 is combined with the power supply device 1 at time t2. During the period in which the light source module 201 is combined with the power supply device 1 (before time t1), the on-duty of the PWM signal Y1 is T2/T1, and the power supply circuit 12 adjusts the value of the load current Io to the target value Io1. .. When the light source module 202 is combined with the power supply device 1 (after time t2), the on-duty of the PWM signal Y1 is T3/T1 (T3>T2), and the power supply circuit 12 sets the value of the load current Io to the target value. Adjust to Io2 (Io2>Io1).

As described above, when the light source module 2 is replaced with the light source module 202 from the light source module 201, the arithmetic circuit 131 can use the control data that matches the specifications of the light source module 202 after the replacement. As a result, when the light source module 201 is combined with the power supply device 1, the arithmetic circuit 131 can control the value of the load current Io to the target value Io1. When the light source module 202 is combined with the power supply device 1, the arithmetic circuit 131 can control the value of the load current Io to the target value Io2.

(2) The setting data preferably includes information on at least one of the light control function and the color control function of the light source 21. The arithmetic circuit 131 performs the rewriting process based on the information regarding the dimming function and the toning function of the light source 21 included in the setting data.

For example, assume that the light source module 2 is replaced with the light source module 201 of the first specification by the light source module 202 of the second specification (see FIG. 1 ). In the specifications of the light source module 201, the light control function and the color control function cannot be used. According to the specifications of the light source module 202, the dimming function and the toning function can be used. Then, it is assumed that the light source module 2 is replaced with the light source module 202 from the light source module 201. In this case, in the replaced light source module 202, the setting circuit 22 generates setting data for using the dimming function and the toning function, and sends a setting signal including the setting data to the arithmetic circuit 131. The arithmetic circuit 131 rewrites the data relating to the dimming function and the toning function among the control data (control program and control parameters) stored in the memory 132 based on the setting data. That is, in the control data stored in the memory 132, the dimming function and the toning function are changed from unavailable to available. The setting data is, for example, a program module relating to the light control function and the color control function. Further, the setting data may be module designation information or the like that designates a program module relating to the light control function and the color control function as the program module executed by the arithmetic circuit 131.

As a result, when the light source module 201 is combined with the power supply device 1, the arithmetic circuit 131 cannot execute the dimming function and the toning function. Then, when the light source module 202 is combined with the power supply device 1, the arithmetic circuit 131 can execute the light control function and the color control function.

(3) The setting data preferably includes information on the dimming curve of the light source 21. The arithmetic circuit 131 performs the rewriting process based on the information regarding the dimming curve of the light source 21 included in the setting data.

For example, assume that the light source module 2 is replaced with the light source module 201 of the first specification by the light source module 202 of the second specification (see FIG. 1 ). In the specifications of the light source module 201, the first dimming curve is used as the dimming curve. In the specifications of the light source module 202, the second dimming curve is used as the dimming curve. Then, it is assumed that the light source module 2 is replaced with the light source module 202 from the light source module 201. In this case, in the replaced light source module 202, the setting circuit 22 generates the setting data including the information of the second dimming curve, and transmits the setting signal including the setting data to the arithmetic circuit 131. The arithmetic circuit 131 rewrites the data regarding the dimming curve among the control data (control program and control parameters) stored in the memory 132 based on the setting data. That is, in the control data stored in the memory 132, the data regarding the dimming curve is changed from the first dimming curve to the second dimming curve. The setting data is, for example, a program module regarding the second dimming curve. Further, the setting data may be module designation information or the like that designates a program module regarding the second dimming curve as a program module executed by the arithmetic circuit 131.

As a result, when the light source module 201 is combined with the power supply device 1, the arithmetic circuit 131 uses the first dimming curve as the dimming curve. When the light source module 202 is combined with the power supply device 1, the arithmetic circuit 131 uses the second dimming curve as the dimming curve.

(4) The setting data preferably includes information regarding control of the light source 21 based on the output of the sensor. The sensor is, for example, a motion sensor or an illuminance sensor. The sensor is attached to the light source module 2 or arranged in the illumination space outside the illumination device A1. The sensor outputs a sensor signal including the detection result to the power supply device 1 via a wired signal transmission path or a wireless signal transmission path. The arithmetic circuit 131 performs the rewriting process based on the information regarding the control of the light source 21 based on the output of the sensor, which is included in the setting data.

For example, assume that the light source module 2 is replaced with the light source module 201 of the first specification by the light source module 202 of the second specification (see FIG. 1 ). According to the specifications of the light source module 201, lighting control such as lighting control, extinction control, and dimming control of the light source 21 based on the output of the human sensor or the illuminance sensor is not possible. The specification of the light source module 202 allows the illumination control of the light source 21 based on the output of the motion sensor or the illuminance sensor. Then, it is assumed that the light source module 2 is replaced with the light source module 202 from the light source module 201. In this case, in the replaced light source module 202, the setting circuit 22 generates setting data for using the illumination control of the light source 21 based on the output of the motion sensor or the illuminance sensor, and outputs the setting signal including this setting data. It is transmitted to the arithmetic circuit 131. Based on the setting data, the arithmetic circuit 131 outputs, from the control data (control program and control parameters) stored in the memory 132, data relating to the illumination control of the light source 21 based on the output of the motion sensor or the illuminance sensor. rewrite. That is, in the control data stored in the memory 132, the illumination control of the light source 21 based on the output of the motion sensor or the illuminance sensor is changed from unavailable to usable. The setting data is, for example, a program module relating to the illumination control of the light source 21 based on the output of the motion sensor or the illuminance sensor. Further, the setting data may be module designation information or the like that designates a program module relating to illumination control of the light source 21 based on the output of a human sensor or an illuminance sensor as a program module executed by the arithmetic circuit 131.

As a result, when the light source module 201 is combined with the power supply device 1, the arithmetic circuit 131 cannot execute the illumination control of the light source 21 based on the output of the motion sensor or the illuminance sensor. When the light source module 202 is combined with the power supply device 1, the arithmetic circuit 131 can execute the illumination control of the light source 21 based on the output of the motion sensor or the illuminance sensor.

(5) It is preferable that the setting data includes information regarding an interlocking operation with an external device other than the own device. The arithmetic circuit 131 performs the rewriting process based on the information regarding the interlocking operation with the external device included in the setting data. The external device is, for example, another lighting device A1, an electric curtain, an electric lock, or the like. The linked operation with the external device includes lighting control of the light source 21 linked with the external device.

For example, assume that the light source module 2 is replaced with the light source module 201 of the first specification by the light source module 202 of the second specification (see FIG. 1 ). According to the specifications of the light source module 201, an interlocking operation with an external device is not possible. According to the specifications of the light source module 202, an interlocking operation with an external device is possible. Then, it is assumed that the light source module 2 is replaced with the light source module 202 from the light source module 201. In this case, in the replaced light source module 202, the setting circuit 22 generates setting data for utilizing the interlocking operation with the external device, and sends the setting signal including the setting data to the arithmetic circuit 131. The arithmetic circuit 131 rewrites the data regarding the interlocking operation with the external device among the control data (control program and control parameters) stored in the memory 132 based on the setting data. That is, in the control data stored in the memory 132, the linked operation with the external device is changed from unavailable to available. The setting data is, for example, a program module related to an interlocking operation with an external device. Further, the setting data may be module designation information or the like that designates a program module relating to an interlocking operation with an external device as a program module executed by the arithmetic circuit 131.

As a result, when the light source module 201 is combined with the power supply device 1, the arithmetic circuit 131 cannot execute the interlocking operation with the external device. Then, when the light source module 202 is combined with the power supply device 1, the arithmetic circuit 131 can perform an interlocking operation with an external device.

As described above, the illumination device A1 does not need to use the drive current generation module as in Patent Document 1 described above, and can reduce the number of components. Further, the illumination device A1 can easily rewrite the control data in the memory 132 so that the control data matches the specifications of the light source module 2.

Further, it is preferable that the setting circuit 22 transmits an identification signal including unique identification information given to the light source module 2 to the power supply device 1 in advance. In the present embodiment, the setting circuit 22 transmits the identification signal to the power supply device 1 before transmitting the setting signal to the power supply device 1. The identification information preferably corresponds to the specifications of the light source module 2.

The arithmetic circuit 131 determines whether to perform the rewriting process based on the identification information. The memory 132 stores in advance identification information (permission identification information) of at least one light source module 2 compatible with the power supply device 1. If the identification information received from the light source module 2 is included in the permission identification information, the arithmetic circuit 131 determines to perform the rewriting process. If the identification information received from the light source module 2 is not included in the permission identification information, the arithmetic circuit 131 determines that the rewriting process is not performed. When the arithmetic circuit 131 determines to perform the rewriting process, it transmits a transmission request signal requesting the transmission of the setting signal to the setting circuit 22. Upon receiving the transmission request signal, the setting circuit 22 transmits the setting signal to the arithmetic circuit 131.

Therefore, when the arithmetic circuit 131 determines not to perform the rewriting process, the setting circuit 22 does not transmit the setting signal, so that the lighting device A1 can suppress useless communication.

Further, in the power supply device 1, the display data generation unit 14 generates the display data regarding the rewriting process according to the instruction of the arithmetic circuit 131. The display data generation unit 14 outputs the generated display data to the display unit 15. The display unit 15 displays the content regarding the rewriting process based on the display data. The content related to the rewriting process is, for example, the status (elapsed state or state) of the rewriting process.

When the display unit 15 includes one LED as one solid-state light emitting element, the display data generation unit 14 generates display data so as to realize the following operation of the display unit 15. The LED of the display unit 15 is normally off. The LED of the display unit 15 lights up when the arithmetic circuit 131 receives the setting signal, blinks when the arithmetic circuit 131 is in the process of rewriting, and lights for a certain period of time when the arithmetic circuit 131 completes the rewriting process. Further, when the arithmetic circuit 131 determines to perform the rewriting process, the LED of the display unit 15 may be turned on for a certain period of time. Further, when the arithmetic circuit 131 determines that the rewriting process is not performed, the LED of the display unit 15 may be kept in the off state.

Further, when the display unit 15 includes a plurality of solid-state light emitting elements including a plurality of LEDs having different emission colors, the display data generation unit 14 generates display data so as to realize the following operation of the display unit 15. .. First, the display data generation unit 14 selects an LED to be turned on from a plurality of LEDs according to the content displayed on the display unit 15. For example, the display unit 15 includes a red LED that emits red light and a green LED that emits green light. In this case, if the arithmetic circuit 131 determines to perform the rewriting process, the green LED is turned on and the red LED is turned off in the display unit 15. When the arithmetic circuit 131 determines that the rewriting process is not performed, the green LED is turned off and the red LED is turned on in the display unit 15.

Further, when the display unit 15 includes a plurality of LEDs having the same emission color as the plurality of solid-state light emitting elements, the display data generation unit 14 generates display data so as to realize the following operation of the display unit 15. First, the display data generation unit 14 switches the number of LEDs to be turned on among the plurality of LEDs according to the content displayed on the display unit 15. For example, the display unit 15 has three LEDs. In this case, if the arithmetic circuit 131 determines to perform the rewriting process, only one of the three LEDs is turned on in the display unit 15. When the arithmetic circuit 131 is in the process of rewriting, two LEDs of the three LEDs are turned on in the display unit 15. When the arithmetic circuit 131 completes the rewriting process, the three LEDs are turned on in the display unit 15. If the arithmetic circuit 131 determines that the rewriting process is not performed, the three LEDs on the display unit 15 are turned off.

If the display unit 15 is a display device such as an LCD, the display data generation unit 14 generates image data to be displayed on the display unit 15 as display data. The display unit 15 that has received the display data causes the display device to display the status of the rewriting process and the like using characters, symbols, and symbols.

The display unit 15 may be a mobile terminal that can be carried by the user. The mobile terminal is, for example, a dedicated terminal, a smartphone, a mobile phone, or the like. In this case, the display data generation unit 14 has a communication function capable of wireless communication with the mobile terminal, and transmits the display data to the mobile terminal. The mobile terminal receiving the display data displays the display data on the screen of the mobile terminal. The communication between the display data generation unit 14 and the mobile terminal may be wired communication.

(First modification)
FIG. 4 shows a first modification of the lighting device A1.

In the illumination device A1 of the first modified example, the power supply device 1 includes an AC-DC converter 11A as the DC power supply 11. AC power is supplied to the AC-DC converter 11A from the commercial power supply 9. The commercial power supply 9 is, for example, a commercial power system having a nominal voltage of 100 V or 200 V and a frequency of 50 Hz or 60 Hz, and supplies AC power to the AC-DC converter 11A.

The AC-DC converter 11A preferably has a power factor improving function.

Further, in the illumination device A1 of the first modified example, the power supply device 1 and the light source module 2 are connected by one cable assembly CA1. The cable assembly CA1 includes a connector plug CN1, a cable W11, and a connector plug CN2. The connector plug CN1 is connected to the first end of the cable W11, and the connector plug CN2 is connected to the second end of the cable W11. The power supply device 1 includes a receptacle (not shown) into which the connector plug CN1 fits. The light source module 2 includes a receptacle (not shown) into which the connector plug CN2 fits. The cable W11 has four electric wires respectively corresponding to the pair of power supply paths W1 and W2 and the pair of communication paths W3 and W4 (see FIG. 1). The pins of the connector plug CN1 and the pins of the connector plug CN2 are electrically connected to each other by the electric wires of the cable W11. That is, the cable assembly CA1 constitutes a part of each of the pair of power supply paths W1 and W2 and the pair of communication paths W3 and W4.

Therefore, by attaching/detaching the cable assembly to/from the power supply device 1 and the light source module 2, it becomes easier to replace the light source module 2 to be combined with the power supply device 1, as compared with a connection structure using a screw terminal block or soldering.

In addition, in FIG. 4, the power supply device 1 and the light source module 2 are connected via one cable assembly. However, the power supply device 1 and the light source module 2 may be connected via two cable assemblies. The two cable assemblies are a first cable assembly that constitutes a part of each of the pair of power supply paths W1 and W2, and a second cable assembly that constitutes a part of each of the pair of communication paths W3 and W4.

(Second modified example)
FIG. 5 shows a second modification of the lighting device A1. In the second modified example, as in the first modified example, an AC-DC converter 11A is provided as the DC power supply 11.

In the illumination device A1 of the second modified example, the power supply device 1 and the light source module 2 are connected by one cable assembly CA2. The cable assembly CA2 includes a connector plug CN11, a cable W12, and a connector plug CN12. The connector plug CN11 is connected to the first end of the cable W12, and the connector plug CN12 is connected to the second end of the cable W12. The power supply device 1 includes a receptacle (not shown) into which the connector plug CN11 fits. The light source module 2 includes a receptacle (not shown) into which the connector plug CN12 fits. The cable W12 has two electric wires corresponding to the pair of power supply paths W1 and W2 (see FIG. 1). The pins of the connector plug CN11 and the pins of the connector plug CN12 are electrically connected to each other by the electric wires of the cable W12. That is, the cable assembly CA2 constitutes a part of each of the pair of power supply paths W1 and W2.

Further, the power supply device 1 includes the wireless communication circuit 16, and the pair of communication ports of the arithmetic circuit 131 is connected to the wireless communication circuit 16. The light source module 2 includes a wireless communication circuit 24, and a pair of communication ports of the setting circuit 22 (for example, a pair of communication ports of the integrated circuit 225 in FIG. 2) are connected to the wireless communication circuit 24. The wireless communication circuit 16 and the wireless communication circuit 24 can transmit and receive wireless signals to and from each other. The wireless communication circuit 16 and the wireless communication circuit 24 comply with, for example, a standard such as ZIGBEE (registered trademark), BLUETOOTH (registered trademark), or a wireless LAN (for example, IEEE 802.11, IEEE 802.15.1, or IEEE 802.15.4). In accordance with this, signal transmission and signal reception are performed.

Therefore, the arithmetic circuit 131 and the setting circuit 22 can transmit and receive signals to and from each other via the wireless signal transmission path. Then, the setting circuit 22 transmits the setting signal to the power supply device 1 via the wireless signal transmission path. The arithmetic circuit 131 receives the setting signal via the wireless signal transmission path. As a result, it is not necessary to connect the power supply device 1 and the light source module 2 with an electric wire, a cable, a cable assembly, or the like for transmitting the setting signal, and the configuration of the lighting device A1 can be simplified.

Further, it is preferable that the setting circuit 22 transmits the setting signal after receiving an instruction to start transmitting the setting signal from outside the light source module 2. In FIG. 5, the operation terminal 3 that can be carried by a person exists outside the illumination device A1. The operation terminal 3 is configured to be able to transmit a wireless signal including a desired command by a human operation. Then, the operation terminal 3 transmits a setting request signal including a setting start command by a human operation. In the light source module 2, when the wireless communication circuit 24 receives the setting request signal, the setting circuit 22 reads the setting start command from the setting request signal and transmits the setting signal via the wireless communication circuit 24. The light source module 2 may include a wired communication circuit, and the wired communication circuit may perform wired communication with the operation terminal 3. In this case, the wired communication circuit and the operation terminal 3 are communicably connected to each other via a communication line.

Therefore, the execution timing of the rewriting process can be arbitrarily determined.

(Third modification)
FIG. 6 shows a third modification of the lighting device A1.

The power supply device 1 of the third modified example includes a PLC circuit 17 having an interface function of power line communication (PLC) instead of the wireless communication circuit 16 of the second modified example. The light source module 2 of the third modified example includes a PLC circuit 25 having an interface function for power line communication, instead of the wireless communication circuit 24 of the second modified example. The PLC circuit 25 receives the setting signal output from the setting circuit 22. The PLC circuit 25 is connected to the power supply paths W1 and W2, and superimposes the modulation signal of the setting signal on the voltage between the power supply paths W1 and W2. The PLC circuit 17 is connected to the power supply paths W1 and W2 and demodulates the setting signal from the voltage between the power supply paths W1 and W2. The PLC circuit 17 delivers the demodulated setting signal to the arithmetic circuit 131.

Therefore, in the lighting device A1, the power supply path of the cable assembly CA2 also serves as a communication path, and the configuration of the lighting device A1 can be simplified.

(Fourth modification)
FIG. 7 shows a fourth modification of the lighting device A1.
