An optical system 2000 has been proposed (see, for example, Patent Documents 1 and 2).

  This conventional dimming system 2000 controls the amount of light of a plurality of illumination devices X connected to the duct LD by one dimmer T.

  Therefore, the light quantity of the lighting device cannot be individually controlled according to the nature of the exhibit and the user's request.

  Therefore, in another conventional dimming system 3000, one lighting device X is provided with one dimmer T for one exhibit P according to the nature of the exhibit P and the user's request. Some are dimming (Figure 7).

  Since this conventional dimming system 3000 requires a plurality of dimmers, it is very expensive.

  There has also been proposed a dimming system 4000 that controls each lighting device X by radio, power line communication, dedicated communication, etc. of one control device Y (FIG. 8).

  Embodiments according to the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram illustrating an example of a configuration of a power supply control system 1000 according to a first embodiment which is an aspect of the present invention. FIG. 2 is a block diagram showing an example of the configuration of the illumination device 100a shown in FIG. In addition, in FIG. 2, although the structure of the illuminating device 100a is described as an example, the other illuminating devices 100b-100i shown in FIG. 1 also have the structure similar to the illuminating device 100a.

  As shown in FIG. 1, the dimming system 1000 includes an infrared remote controller RC, and a plurality (9 in the example of FIG. 1) lighting devices 100a, 100b, 100c, 100d, 100e, 100f, 100g, 100h, and 100i. Wiring LI1, LI2 and ducts LD1, LD2 are provided.

  As shown in FIG. 1, the wiring LI1 supplies the power supply voltage output from the power supply AC to the plurality of lighting devices 100a to 100d.

  The wiring LI2 supplies the power supply voltage output from the power supply AC to the plurality of lighting devices 100e to 100i.

  The duct LD1 is connected to the plurality of lighting devices 100a to 100d and accommodates the wiring LI1.

  The duct LD2 is connected to the plurality of lighting devices 100e to 100i and accommodates the wiring LI2.

  The infrared remote controller RC can output an infrared command signal.

  When each of the lighting devices 100a to 100i receives the first infrared command signal output from the infrared remote controller RC and specifying at least the identification information in the identification information storage mode, the identification specified by the first infrared command signal Information is memorized.

  On the other hand, when the illumination devices 100a to 100i receive the second infrared command signal that is output from the infrared remote controller RC and defines the identification information and the dimming rate in the normal mode, When the identification information defined by the second infrared command signal matches, the dimming rate defined by the second infrared command signal is stored and light is emitted at the dimming rate defined by the second infrared command signal. It is like that.

  In the example of FIG. 1, identification information (ID01 to ID09) is stored in each of the lighting devices 100a to 100i.

  Here, as illustrated in FIGS. 1 and 2, the illumination device 100a includes a control circuit CON, a power supply circuit SC, a light emitting unit LE, a switch SW, an infrared light receiving unit LR, and a resistance element R. .

  The infrared light receiver LR receives an infrared command signal output from the infrared remote controller RC.

  One end of the resistance element R is connected to the terminal SCT. The other end of the resistance element R is connected to the input unit I.

  In addition, the switch SW sets the control mode of the control unit C to the normal mode in which light is emitted at the dimming rate stored in the control circuit CON (storage unit M), or the identification information to the control circuit CON (storage unit M). One of the stored identification information storage modes is switched.

  One end of the switch SW is connected to the input unit I (the other end of the resistance element R). The other end of the switch SW is connected to the ground.

  This switch SW is turned on by the first operation by the user. As a result, a “Low” level identification information switching signal is input to the input unit I. The “Low” level identification information switching signal defines the identification information storage mode.

  On the other hand, the switch SW is turned OFF by the second operation by the user. As a result, an identification information switching signal of “High” level is input to the input unit I. The identification information switching signal of “High” level defines the normal mode.

  That is, in the illumination device 100 (control circuit CON), the control mode is switched to the identification information storage mode by the first operation on the switch SW by the user.

  On the other hand, in the lighting device 100 (control circuit CON), the control mode is switched to the normal mode by the second operation on the switch SW by the user.

  The power supply circuit SC is supplied with a power supply voltage from the power supply AC via the wiring LI1, and outputs power corresponding to the dimming control signal. In addition, the power supply circuit SC outputs a voltage generated from the power supply voltage to the terminal SCT.

  The light emitting unit LE emits light by power output from the power supply circuit SC.

  The light emitting unit LE is a light emitting device capable of dimming, for example, a fluorescent lamp, an LED element, or an organic EL element.

  As described above, the other lighting devices 100b to 100i shown in FIG. 1 have the same configuration as the lighting device 100a.

  That is, the plurality of lighting devices 100a to 100i each include a control circuit CON, a power supply circuit SC, a light emitting unit LE, a switch SW, an infrared light receiving unit LR, and a resistance element R.

  For example, the identification information (ID01) stored in the first lighting device 100a among the plurality of lighting devices 100a to 100i is the identification stored in the second lighting device 100b among the plurality of lighting devices 100. It is set differently from the information (ID02).

  Thereby, the two illuminating devices 100a and 100d can be individually controlled by individually defining the identification information with the infrared command signal.

  For example, in the example illustrated in FIG. 1, the dimming rate stored in the first lighting device 100 a is different from the dimming rate stored in the second lighting device 100 b. In this way, different dimming rates may be set for different lighting devices.

  That is, the dimming rates of the two lighting devices 100a and 100c can be individually controlled.

  For example, the identification information (ID01) stored in the first lighting device 100a is the same as the identification information (ID03) stored in the third lighting device 100c among the plurality of lighting devices 100a to 100i. (That is, identification information (ID03) is stored in the first lighting device 100a). In this way, the same identification information may be stored in different lighting devices.

  As a result, the identification information of the two illumination devices 100a and 100c can be simultaneously specified by one infrared command signal, so that the dimming rates of the two illumination devices 100a and 100c can be controlled in synchronization.

  Further, for example, when each of the lighting devices 100a to 100i receives the second infrared command signal in the normal mode, the stored identification information is different from the identification information defined by the second infrared command signal. Sometimes it emits light at the stored dimming rate.

  Each lighting device 100a to 100i emits light at the stored dimming rate when the control mode is the normal mode at the time of restart.

  Thereby, reduction of the power consumption of each illuminating device 100a-100i can be aimed at.

  When each of the lighting devices 100a to 100i receives the first infrared command signal that further defines the dimming rate in the identification information storage mode, the identification information and the dimming defined by the first infrared command signal are received. May be stored, and light may be emitted at a dimming rate defined by the first infrared command signal.

  The control circuit CON stores identification information defined by the first infrared command signal received by the infrared light receiving unit LR in the identification information storage mode.

  Further, in the normal mode, the control circuit CON determines whether or not the identification information defined by the second infrared command signal received by the infrared light receiving unit LR matches the stored identification information. .

  Then, in the normal mode, when the identification information defined by the second infrared command signal matches the stored identification information, the control circuit CON performs light control defined by the second infrared command signal. The dimming control signal is output based on the dimming rate defined by the second infrared command signal.

  On the other hand, in the normal mode, the control circuit CON discards the second infrared command signal when the identification information defined by the second infrared command signal does not match the stored identification information. That is, the control state of the lighting device 100a maintains the same state as that before the second infrared command signal is input.

  Here, as illustrated in FIG. 2, the control circuit CON includes, for example, a decoding unit D, an input unit I, a storage unit M, and a control unit C.

  The decode unit D decodes the infrared command signal received by the infrared light receiving unit LR and outputs the obtained decode signal.

  The input unit I receives a mode switching signal corresponding to the operation state of the switch SW.

  The memory | storage part M memorize | stores identification information and a light control rate. The storage unit M is a nonvolatile storage device (for example, EEPROM).

  When the mode switching signal defines the identification information storage mode, the control unit C stores the identification information defined by the decode signal in the storage unit M.

  Further, when the mode switching signal defines the normal mode, the control unit C determines whether or not the identification information defined by the decode signal matches the identification information stored in the storage unit M. To come to judge.

  When the identification information specified by the decode signal matches the identification information stored in the storage unit M, the control unit C causes the storage unit M to store the dimming rate specified by the decode signal. The dimming control signal is output based on the dimming rate defined by the decode signal.

  On the other hand, when the identification information defined by the decode signal does not match the identification information stored in the storage unit M, the control unit C discards the decode signal. That is, in this case, as described above, the second infrared command signal is discarded.

  As described above, the other lighting devices 100b to 100i also have the same configuration as the lighting device 100a.

  Next, an example of operation | movement of the light modulation system 1000 which has the above structures is demonstrated.

  Here, FIG. 3 is a diagram illustrating an example of a state in which the identification information of the first lighting device 100a of the light control system 1000 illustrated in FIG. 1 is stored. FIG. 4 is a diagram illustrating an example of a state in which the identification information of the second lighting device 100b of the light control system 1000 illustrated in FIG. 1 is stored. FIG. 5 is a diagram illustrating an example of a state in which the identification information of the ninth lighting device 100i of the dimming system 1000 illustrated in FIG. 1 is stored.

  In the state illustrated in FIG. 3, the identification information is not stored in the lighting devices 100 b to 100 i. The switches SW of the lighting devices 100b to 100i are OFF, and the control mode of the lighting devices 100b to 100i is the normal mode. Further, the switch SW of the lighting device 100a is turned on, and the control mode of the lighting device 100a is the identification information storage mode.

  First, for example, as shown in FIG. 3, a first infrared command signal defining identification information (ID01) is output from the infrared remote controller RC to the illumination device 100a whose control mode is the identification information storage mode.

  The lighting device 100a whose control mode is the identification information storage mode receives the first infrared command signal that is output from the infrared remote controller RC and that defines at least the identification information, and the identification information that is defined by the first infrared command signal (ID01) is stored.

  The other lighting devices 100b to 100i do not store identification information because the control mode is the normal mode.

  Next, as shown in FIG. 4, for example, the user turns off the switch SW of the lighting device 100a and turns on the switch SW of the lighting device 100b. That is, the control mode of the illumination device 100a is the normal mode, and the control mode of the illumination device 100b is the identification information storage mode.

  And the 1st infrared command signal which prescribes | regulates identification information (ID02) from the infrared remote control RC is output to the illuminating device 100b whose control mode is identification information storage mode.

  The lighting device 100b whose control mode is the identification information storage mode receives the first infrared command signal that is output from the infrared remote controller RC and defines at least the identification information, and the identification information that is defined by the first infrared command signal (ID02) is stored.

  The other lighting devices 100a and 100c to 100i do not store identification information because the control mode is the normal mode.

  And the same operation is performed about the illuminating devices 100c-100h.

  Finally, as shown in FIG. 5, for example, the user turns off the switch SW of the lighting device 100h and turns on the switch SW of the lighting device 100i. That is, the control mode of the illumination device 100h is the normal mode, and the control mode of the illumination device 100i is the identification information storage mode.

  And the 1st infrared command signal which prescribes | regulates identification information (ID09) from the infrared remote control RC is output to the illuminating device 100h whose control mode is identification information storage mode.

  The illumination device 100h whose control mode is the identification information storage mode receives the first infrared command signal that is output from the infrared remote controller RC and defines at least the identification information, and the identification information that is defined by the first infrared command signal (ID09) is stored.

  Through the above operation, each identification information (ID01 to ID09) is stored in each of the lighting devices 100a to 100i.

  The lighting devices 100a to 100i whose control mode is the normal mode receive the second infrared command signal that is output from the infrared remote controller RC and that defines the identification information and the dimming rate, and stores the stored identification. When the information matches the identification information specified by the second infrared command signal, the dimming rate specified by the second infrared command signal is stored and the dimming specified by the second infrared command signal Light is emitted at a rate.

  As described above, the light control system according to one aspect of the present invention stores the infrared remote controller RC that can output an infrared command signal, the control mode, the normal mode that emits light at the stored light control rate, and the identification information. A plurality of illumination devices 100a to 100i each having a switch SW for switching between the identification information storage modes to be performed and an infrared light receiving unit LR that receives an infrared command signal output from the infrared remote controller RC, and a power supply voltage output from a power source Wirings LI1 and LI2 for supplying to a plurality of lighting devices.

  The lighting device stores, for example, identification information defined by the first infrared command signal received by the infrared light receiving unit LR in the identification information storage mode, and received by the infrared light receiving unit LR in the normal mode. When the identification information defined by the second infrared command signal and the stored identification information match, the dimming rate defined by the second infrared command signal is stored and the second infrared A control circuit CON that outputs a dimming control signal based on a dimming rate specified by the command signal, and a power supply circuit SC that is supplied with power supply voltage from a power supply via a wiring and outputs power corresponding to the dimming control signal And a light emitting unit LE that emits light by the electric power output from the power supply circuit SC.

  Therefore, the dimming system according to the present invention can individually control the dimming rates of a plurality of lighting devices by one infrared remote controller.

  That is, versatility can be improved while reducing the introduction cost.

  And the light control system which concerns on this invention is applicable to an art museum, a store, and a general house, for example.

  In addition, the dimming system can control all lighting devices (spotlights, downlights, ceilings, indirect lighting, etc.) in the same space with the same kind of functions with a single infrared remote controller RC.

  Further, since the lighting device operates at the dimming rate stored in the storage unit at the time of restart, the dimming rate can be set low in advance.

  Thereby, as described above, the power consumption of the lighting device can be reduced.

  In addition, by storing the identification information in the storage unit (EEPROM), for example, the user can be changed even after the layout is changed.

  In the dimming system, dimming control is also possible for lighting devices with different input wiring systems.

  In the dimming system, an illumination device that is not a dimming target may be operated without providing identification information.

  Further, as described above, the same identification information may be stored in different lighting devices. Thereby, the dimming rate of two illuminating devices can be controlled synchronously.

  In the identification information storage mode, for convenience of explanation, a dimming system was set up so that when the lighting device was lit, the other lighting devices were not lit, but if the control mode is in the identification information storage mode, There is no problem with either lighting or non-lighting of the device.

  In addition, embodiment is an illustration and the range of invention is not limited to them.
