Description

  The present invention relates to a lighting system that sends a control signal to a luminaire connected to a power line via the power line and controls the operation of the luminaire with the control signal.

  Conventionally, for example, in order to illuminate museum exhibits, museum exhibits, and store products, a plurality of lighting fixtures having dimming functions and human detection sensor terminals are attached to a so-called wiring duct disposed on the ceiling surface. An illumination system that performs blinking control and dimming control of a lighting fixture according to detection information of a human detection sensor terminal is provided (see, for example, Patent Document 1).

  In this lighting system, if a dedicated control signal line is connected to a lighting fixture or human detection sensor terminal, the lighting fixture or human detection sensor terminal cannot be easily attached to or detached from the wiring duct. A power line carrier communication method is used in which a high-frequency signal is superimposed on the supplied commercial power supply. This power line carrier communication system has recently improved the transmission performance against noise generated by other devices connected to the power line by adopting spread spectrum technology, etc. Adopted by the Echonet Consortium.

  Further, as an illumination system using the power line carrier communication system, for example, there is an illumination system as disclosed in Patent Document 2 if not limited to a wiring duct. In this system, individual channel data is assigned to the luminaire connected to the power line, and the controller connected to the power line is assigned to the luminaire to be controlled according to the switch operation or the output of the sensor or timer. The power line carrier signal including the channel data is transmitted to the power line, and the lighting apparatus that receives the power line carrier signal performs flashing control and dimming control.

  Furthermore, there is also an illumination system that connects at least one brightness sensor and a plurality of lighting fixtures to the same dedicated bus line, transmits a serial signal via the dedicated bus line, and controls the lighting state of the lighting fixture. Traditionally provided. This system is called the DALI (Digital Addressable Lighting Interface) system (specified in IEC 60929), which is being researched and developed mainly in Europe in recent years. In this system, multiple lighting fixtures are turned on / off collectively. Therefore, a group address is assigned to each luminaire, and when changing the group assignment by changing the layout, etc., the layout address can be changed by changing the group address of each luminaire.

  FIG. 16 is a system configuration diagram of the DALI system. This system includes a controller 100 connected to the signal bus line L3, and a plurality of lighting fixtures 110a connected to the controller 100 via the signal bus line L3. The bus power supply device 120 supplies power to the signal bus line L3.

  FIG. 17 is a block diagram of this system. The controller 100 includes an operation unit 101 configured by switches and the like for performing various settings, a storage unit 102 such as an EEPROM for storing setting contents, and a group address to be controlled. The signal transmission unit 103 transmits a control signal including address data to be displayed and control data indicating a dimming level to the signal bus line L3, and a control unit 104 that controls each unit. In addition, the lighting fixtures 110a... Receive a control signal transmitted via the signal bus line L3, a lighting load 112 such as a fluorescent lamp, and supply power to the lighting load 112 to supply the lighting load. A lighting circuit unit 113 for lighting 112, a storage unit 114 configured by an EEPROM or the like for storing setting data such as its own group address, and a group address included in a control signal received by the signal receiving unit 111 are stored in the storage unit 114. A control unit 115 that controls the output of the lighting circuit unit 113 according to the control data included in the control signal when it matches the stored self group address.

  In this DALI system, the controller 100 designates the group address to which the lighting fixture 110a to be controlled belongs, and directly transmits the dimming level, or increases or decreases the dimming level by a preset change. The up / down commands are transmitted to control the lighting fixtures 110a belonging to a desired group. In this system, the scene number and the dimming level corresponding to the scene number are set in advance in the storage unit 114 of each lighting fixture 110a... And the lighting fixture 110a to be controlled according to the operation of the operation unit 101 of the controller 100. When the control signal including the address data of the group to which the ... belongs and the control data indicating the scene number is sent from the controller 100, the lighting fixtures 110a belonging to the group address of the control signal are set in the storage unit 114. Based on the number and the dimming level corresponding thereto, the lighting load 112 is dimmed at a desired dimming level. Here, the scene indicates a human life scene such as “lunch break”, and a plurality of lighting fixtures installed in the same area (for example, the same room) are lit at a dimming level set for each appliance. In the storage unit 114 of each luminaire 110a..., A scene number indicating an individual scene and a light control level at that time are set. Table 1 shows an example of combinations of dimming levels for each lighting apparatus 110a... For each scene.

Japanese Patent Laid-Open No. 57-176691 JP-A-57-52331

  In the lighting system of FIG. 16 described above, a plurality of lighting fixtures 110a... Can be lit at a dimming level set in advance for each scene, but a signal bus line L3 is connected separately from the power line L1. There is a need. Therefore, in the lighting system of FIG. 16, a system that controls the lighting state of the lighting fixtures 110a... By using the power line carrier communication method used in the lighting system of Patent Document 1 and transmitting a control signal via the power line L1. Conceivable. That is, in this system, the correspondence relationship between the scene number and the dimming level is stored in advance in each of the lighting fixtures 110a...

FIG. 1 is a block diagram of a lighting system according to the present embodiment, and this system includes a controller 10 connected to a power line L1 of a commercial power source AC and a plurality of lighting fixtures 20a connected to the power line L1. The

  The controller 10 is attached to a wall of a building, for example, and is a second power line communication unit (hereinafter abbreviated as a power line communication unit) that transmits and receives signals via the power line L1 in a power line carrier communication method in which a high frequency current is superimposed on the commercial power supply AC. ) 11, a setting unit 12 that includes input means such as a switch and display means such as an LCD and LED, and performs various settings of the system, and a control unit 13 that includes a microcomputer and controls each of the units 11 and 12. It consists of.

  The lighting fixture 20a is made of a fixture such as a spotlight that is used by being connected to a wiring duct (not shown), for example, and includes a lighting load 21 such as an incandescent lamp and a phase control circuit. A lighting circuit unit 22 for dimming the illumination load 21 by adjusting the lighting load, a storage unit 23 which is composed of a writable nonvolatile memory such as an EEPROM and stores individual illumination load information such as the current dimming level, and commercial A first power line communication unit (hereinafter abbreviated as a power line communication unit) 24 that transmits and receives signals via the power line L1 in a power line carrier communication method in which a high-frequency current is superimposed on the power source AC, and each unit 22 to 24 includes a microcomputer. It is comprised with the control part 25 which performs control of these.

  Note that a fluorescent lamp, an LED, or the like may be used as the illumination load 21. When the lighting load 21 is a fluorescent lamp, the lighting circuit unit 22 may be composed of a copper iron ballast and a phase control circuit, and the dimming control may be performed by adjusting the phase angle. It is composed of a rectifier circuit that rectifies the commercial power supply, a boost chopper circuit that smoothes the output of the rectifier circuit, and an inverter circuit that converts the output of the boost chopper circuit into high frequency power. Dimming may be performed by controlling the high-frequency power supplied to the lamp. When the illumination load 21 is an LED, the lighting circuit unit 22 may be configured by a PWM circuit or the like that converts a DC voltage into a pulse voltage, and dimming may be performed by changing the duty ratio of the pulse voltage applied to the LED. . Furthermore, the R, G, and B LEDs are used as the illumination load 21 and the R, G, and B LEDs are dimmed for each color to control the light color of the combined R, G, and B light. Toning control may be performed, and when toning control is performed, information such as toning information is set in the storage unit 23 as individual illumination load information.

  Next, the operation of this system will be described. First, in order to set a dimming level for each lighting fixture 20a ... from the controller 10, an individual address (identification information) for individually identifying the lighting fixture 20a ... is set to each lighting fixture 20a .... That is, in a state where the controller 10 is connected to the power line L1 and the commercial power supply AC is supplied to the power line L1, the lighting fixtures 20a are attached to the wiring duct one by one and connected to the power line L1. When the lighting fixtures 20a are connected to the power line L1, power is supplied through the power line L1, and the control unit 25 starts operating.

  At this time, since the data of the individual address is not stored in the storage unit 23, the control unit 25 controls the lighting circuit unit 22 to blink the lighting load 21, thereby confirming that the individual address is not set. In addition to notifying the worker, a signal indicating that the individual address is not set is broadcasted from the power line communication unit 24 to the power line L1 (continues to be transmitted for a fixed time). In addition, you may alert | report that the individual address is not set by providing LED for notification in lighting fixture 20a ... and blinking this LED instead of the illumination load 21. FIG.

  In the controller 10, when the power line communication unit 11 receives a signal indicating that the individual address is not set via the power line L1, the control unit 13 does not set the individual address on the display unit of the setting unit 12 based on this signal. When the operator confirms that the individual address has not been set by viewing the display on the setting unit 12 or the blinking of the lighting load 21, the input means of the setting unit 12 is displayed. Enter an individual address using. At this time, the control unit 13 of the controller 10 causes the power line communication unit 11 to send the power line carrier signal including the individual address input using the setting unit 12 to the power line L1. Then, when the power line communication unit 24 receives the power line carrier signal transmitted via the power line L1, in the lighting fixture 20a... In which the individual address has not been set, the control unit 25 automatically stores the data of the individual address included in the power line carrier signal. Are stored in the storage unit 23, the lighting circuit unit 22 is controlled to turn off the illumination load 21, and transmission of a signal indicating that the individual address is not set is stopped. Then, the above operation is repeated until there is no lighting fixture 20a ... for which the individual address is not set, and the controller 10 and the lighting fixture 20a ... send a signal indicating that the individual address is not set on the power line L1. The normal control operation is not started while it is being performed.

  When the operation for setting the individual addresses for the respective lighting fixtures 20a... Is completed as described above, the operation for individually setting the dimming levels of the respective lighting fixtures 20a. That is, when the operator individually inputs the dimming level of each lighting fixture 20a ... using the input means provided in the setting unit 12 of the controller 10, the control unit 13 assigns the individual lighting fixtures 20a ... assigned to the setting target. A power line carrier signal including the address and the input dimming level is transmitted from the power line communication unit 11 to the power line L1. And in lighting fixture 20a ..., the control part 25 compares the individual address contained in the power line carrier signal which the power line communication part 24 received with the individual address set to the memory | storage part 23, and an individual address corresponds. Then, the dimming level included in the power line carrier signal is captured, and the data of the dimming level is stored in the storage unit 23 as individual lighting load information, and the lighting circuit unit 22 is controlled according to the dimming level, and the lighting load 21 Turn on the dimmer.

  In this way, when individual lighting load information (for example, dimming level) is set for each lighting fixture 20a, the control unit 25 of each lighting fixture 20a... Dimming level) and the lighting load 21 so that the lighting load 21 is lit in a lighting state obtained by combining the system state information (for example, on / off signal) from the controller 10 received by the power line communication unit 24. It controls the output.

  Here, the operation of the present system will be described in more detail according to the time chart shown in FIG. This time chart shows an example in which the dimming levels of the three lighting fixtures 20a, 20b, and 20c are set to 100%, 75%, and 50%, respectively. (Not shown), the control unit 13 sends a signal for turning on or off the lighting load 21 from the power line communication unit 11 to the power line L1 as system state information in accordance with the operation of the operation unit. And in each lighting fixture 20a ..., if the power line communication part 24 receives the signal which turns on the illumination load 21 as system state information, while the control part 25 will memorize | store the received system state information in the memory | storage part 23, it will memorize | store it. The output of the lighting circuit unit 22 is controlled to the dimming level obtained by combining the individual dimming level set in the unit 23 and the system state information, and the lighting load 21 is dimmed. When the power line communication unit 24 receives a signal for turning off the lighting load 21 as system information information, the control unit 25 stores the received system state information in the storage unit 23 and does not immediately turn off the lighting load 21. In order to make it known that the light is turned off after the fade-out, the output of the lighting circuit unit 22 is controlled to gradually lower the dimming level to a predetermined level. Is gradually lowered to 0% to finally turn off the illumination load 21 (fade out). The operation of fading out the lighting load 21 when the light is turned off is autonomously performed by the control unit 25 of each lighting fixture 20a ..., and the dimming level that is one step lower than that during normal lighting is the dimming level during normal lighting. Relatively determined accordingly. In the example of FIG. 2, the dimming level that is one step lower than that during normal lighting is set to 75% that during normal lighting, 75% for the lighting fixture 20a, 56.3% for the lighting fixture 20b, The lighting fixture 20c is dimmed at 37.5%.

  Here, in order to adjust the installation position of the lighting fixture 20b, the lighting fixture 20a is removed from the wiring duct at time t1 during lighting, and then connected to the wiring duct at time t2. When the power supply is resumed, the control unit 25 reads the dimming level data (75%) and the system state information (ON signal) from the storage unit 23, and the dimming level and the system state information are read. Since the output of the lighting circuit unit 22 is controlled according to the dimming level obtained by combining and the lighting load 21 is dimmed, the lighting load 21 is lit at the same dimming level as before removal from the wiring duct. Can do. Therefore, it is not necessary to set individual lighting load information every time the lighting fixtures 20a are detached from the wiring duct for position adjustment, and there is an advantage that usability is improved.

(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIG. The configuration of the illumination system of the present embodiment is implemented except that the controller 10 is provided with a time measuring means (not shown) for measuring the current date and time, which is configured by a real time clock IC or a crystal oscillator. Since it is the same as that of the illumination system of the form 1, the same code | symbol is attached | subjected to a common component and the description is abbreviate | omitted.

  Next, the operation of this system will be described with reference to the flowchart of FIG. As described above, the controller 10 has time measuring means for measuring the current date and time, and presets a schedule (for example, a 24-hour schedule) for operating the lighting fixtures 20a ... in a built-in memory (not shown). It is. When the time measured by the time measuring means reaches a preset time, the control unit 13 sends a signal (system state information) for causing the lighting fixtures 20a to perform a predetermined operation in accordance with the schedule set in the memory. A time schedule control of the lighting fixtures 20a is performed by sending the communication unit 11 to the power line L1. Here, the control unit 13 sends a coefficient value for a dimming level (individual lighting load information) set in advance for each lighting fixture 20a as system state information, and each lighting fixture 20a. The unit 25 controls the output of the lighting circuit unit 22 to a level obtained by multiplying the dimming level set in advance in the storage unit 23 by the coefficient value sent from the controller 10, thereby dimming the lighting load 21. . The schedule set in the memory may be a weekly schedule or an annual schedule.

  In the present embodiment, the controller 13 of the controller 10 obtains a coefficient value (system state information) for the dimming level preset for each appliance from the power line communication unit 11 until a predetermined time elapses after the power is turned on. For example, when power is supplied to the power line L1 at a predetermined time every day, system state information is transmitted from the controller 10 to the lighting fixtures 20a, so that the lighting fixtures 20a ... perform a predetermined operation. It has become.

  On the other hand, if the controller 25 of the lighting fixtures 20a cannot receive the system status signal from the controller 10 until the predetermined time elapses after the power is turned on, the controller 25 requests the controller 10 for the latest system status signal. The power line carrier signal with its own individual address added to the signal is sent from the power line communication unit 24 to the power line L1. When the power line communication unit 11 of the controller 10 receives this request signal, the control unit 13 sends the system state information sent last time to the individual address of the lighting fixtures 20a added to the request signal. The lighting apparatus 20a... That has transmitted the request signal can receive the latest system state information transmitted from the controller 10 to perform the same operation as the other lighting apparatuses 20a. Therefore, the lighting fixture 20b is connected to the power line L1 at time t3 after the other lighting fixtures 20a and 20c have already started to operate according to the system state information from the controller 10 with the lighting fixture 20b disconnected from the power line L1. When the power supply is started, the controller 10 has already sent out the system state information. Therefore, the lighting apparatus 20b cannot receive the system state information from the controller 10 even after a predetermined time has elapsed after the power is turned on. Although not possible, the control unit 25 of the lighting fixture 20b has a power line carrier signal in which its own individual address is added to a request signal for requesting the latest system state information when a predetermined time has elapsed since the power was turned on at time t3. Is transmitted from the power line communication unit 24, and the lighting apparatus 2 is received from the controller 10 in response to the request signal.

A third embodiment of the present invention will be described with reference to FIGS. Since the basic configuration of the illumination system is the same as that of the first embodiment, common constituent elements are denoted by the same reference numerals and description thereof is omitted, and the characteristic part of the present embodiment will be described.

  The lighting fixture 20a ... which comprises this system is attached and used for the wiring duct 40 as shown in FIG. The wiring duct 40 has an elongated rectangular parallelepiped shape, and an opening 41 is formed in the lower surface along the longitudinal direction. A pair of conductive plates (see FIG. The power line L1 is connected to the pair of conductive plates, and the commercial power source AC is supplied with power. That is, the power line L1 is constituted by a pair of conductive plates.

  On the other hand, the lighting fixture 20a... Has a lamp main body 31 that houses an illumination load 21 such as an incandescent lamp and its lighting circuit portion 22, and the lamp main body 31 is connected to a wiring duct connector 33 via an arm 32. It is connected to. The upper end of the connector 33 is inserted into the wiring duct 40 through the opening 41, and power is supplied from the wiring duct 40 by bringing a current collector (not shown) provided in the connector 33 into contact with the conductive plate of the wiring duct 40. Yes. Further, the connector 33 is detachably attached to the wiring duct 40 and is slidably connected to the wiring duct 40 in a state of being attached to the wiring duct 40, and can be placed at an arbitrary position in the longitudinal direction of the wiring duct 40. It can be positioned.

  4 is a block diagram of the lighting fixtures 20a, and in this embodiment, a release detection unit 26 is provided for detecting that the connector 33 is removed from the wiring duct 40 in the lighting fixtures 20a described in the first embodiment. The control unit 25 resets the individual illumination load information (dimming level) stored in the storage unit 23 according to the detection signal of the release detection unit 26.

  Next, operation | movement of this illumination system is demonstrated according to the time chart of FIG. This time chart shows an example in which the dimming levels of the three lighting fixtures 20a, 20b, and 20c are set to 100%, 75%, and 50%, respectively. When the operation is performed, the control unit 13 sends a signal for turning on or off the illumination load 21 from the power line communication unit 11 to the power line L1 as system state information in accordance with the operation of the operation unit. And in each lighting fixture 20a ..., if the power line communication part 24 receives the signal which turns on the illumination load 21 as system information information, while the control part 25 will memorize | store the received system state information in the memory | storage part 23, it will memorize | store it. The output of the lighting circuit unit 22 is controlled by the dimming level obtained by combining the individual dimming level set in the unit 23 and the system state information, and the lighting load 21 is dimmed. When the power line communication unit 24 receives a signal for turning off the lighting load 21 as a system information signal, the control unit 25 stores the received system state information in the storage unit 23 and controls the output of the lighting circuit unit 22. The lighting load 21 is turned off after fading out.

  Here, when the lighting fixture 20c is removed from the wiring duct 40 at time t4 when the lighting fixtures 20a... Are turned on at a preset dimming level, the release detection unit 26 of the lighting fixture 20c The removal operation is detected, and the control unit 25 resets the dimming level stored in the storage unit 23 based on the detection signal from the release detection unit 26. Therefore, when the lighting fixture 20c is reconnected to the wiring duct 40 at time t5, power is supplied to the lighting fixture 20c, and the control unit 25 of the lighting fixture 20c controls the default dimming level (for example, 100% dimming level). ) And the system state information (ON signal) stored in the storage unit 23, the output of the lighting circuit unit 22 is controlled, and the lighting load 21 is turned on at a dimming level of 100%. On the other hand, when the power supply to the power line L1 is interrupted at time t6 and then the power supply to the power line L1 is resumed at time t7, the release detection unit 26 of each lighting fixture 20a. Therefore, the control unit 25 does not reset the dimming level information set in the storage unit 23, and the lighting fixtures 20 a... Remain off when the power supply is resumed. When a signal for turning on the lighting load 21 is transmitted as information, each lighting fixture 20a... Is dimmed at a predetermined dimming level in response to the system information signal.

  As described above, in this system, when the lighting fixtures 20a are removed from the wiring duct 40, it is considered that the installation position of the lighting fixtures 20a ... is changed, so that the control unit 25 is set in the storage unit 23. By resetting the light level, it is possible to reset the light control level (individual lighting load information) according to the installation position. In addition, when the power supplied to the power line L1 is shut off due to the end of business hours or the like, the dimming level set in the storage unit 23 is not reset, so the dimming level when the power is turned on again. The operation of the lighting fixtures 20a can be started without resetting.

(Embodiment 4)
A fourth embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a block diagram of the illumination system of this embodiment, and FIG. 8 is a system configuration diagram. In this system, the illumination system of Embodiment 1 is detachably attached to the wiring duct 40 described in Embodiment 3. A plurality of human detection sensor terminals 50a...

  Each person detection sensor terminal 50a ... is a person detection unit 51 such as a PIR sensor that detects the presence or absence of a person by detecting a heat ray radiated from a human body, and a power line carrier communication system that superimposes a high frequency current on a commercial power source AC. The power line communication unit 52 that transmits and receives signals via the power line L1 and the control unit 53 that is configured by a microcomputer and controls each unit, and each human detection sensor terminal 50a is similar to the lighting fixture 20a. An individual address for identifying ... is set. The human detection unit 51 is not limited to a PIR sensor using a pyroelectric element, and a sensor such as an ultrasonic sensor that detects a human body using ultrasonic waves may be used.

  FIG. 9 shows an example of installation in the case where the lighting apparatus 20a... Is installed in a museum and a spotlight is applied to a picture hung on the wall. The controller 10 is installed on the wall near the entrance 83 of the building 80. A wiring duct 40 is installed along the side walls of the rooms 81a to 81f in the building 80, and one lighting fixture 20a is attached to each wiring duct 40 one by one. Further, at least one human detection sensor terminal 50a to 50g is arranged in each of the rooms 81a to 81f. Here, in an art museum or the like, a route through which a visitor moves through the hall is determined in advance, and the person detection sensor terminals 50a to 50f are installed in the vicinity of the entrances 82a to 82f of the rooms 81a to 81f. The admission to the 81f is monitored. In the room 81f at the end of the normal route, a human detection sensor terminal 50g is also installed in the vicinity of the exit 82g to monitor the exit of the person entering the room 81f. Note that reference numeral 90 in FIG. 9 denotes a base lighting device such as a downlight that illuminates each room of the building 80.

  Here, each room 81a-81f of a building is made into one area, the lighting fixture 20a ... installed in each area and the human detection sensor terminal 50a ... are made into one group G1, ... The lighting state of the luminaires 20a is controlled for each area based on the human detection signal of the human detection sensor terminal 50a. That is, group data indicating the group G1 to which the lighting device 20a belongs is set in advance in the storage unit 23 of each lighting fixture 20a, and a system state signal with the group data added is transmitted from the controller 10, and the system state signal is transmitted. Only when the group data added to the group data matches the group data set in the storage unit 23, the system state information is stored in the storage unit 23, and the individual illumination load information and the system state information stored in the storage unit 23 are stored. The control unit 25 performs lighting control according to the above.

  As described above, FIG. 9 shows an installation example in which the lighting fixtures 20a... Are installed in a museum. When people in the hall move according to a preset route, there are areas where there are visitors and areas where visitors move next. It is preferable to turn on the lighting fixtures 20a. That is, in an area where there are no visitors, it is preferable to turn off or dimm the lighting fixtures 20a in order to save energy or prevent discoloration of exhibits such as paintings. However, since there is no door between areas (rooms) in museums, etc., the next area can be seen, so if the lighting equipment in the next area is turned off or dimmed, the visitors feel anxious and uncomfortable There is a case.

  Therefore, in this system, the lighting fixtures 20a in the area where the visitors are located and the area where the visitors move next are turned on, and the lighting fixtures 20a are turned off or dimmed in other areas. Yes. The human detection sensor terminals 50a to 50f are installed near the entrances 82a of the rooms 81a to 81f. For example, when the human detection unit 51 of the human detection sensor terminal 50a installed in the room 81a detects a person, the control unit 53 Transmits a power line carrier signal including its own individual address and human detection signal from the power line communication unit 52 to the power line L1. In the controller 10, when the power line communication unit 11 receives the human detection signal transmitted from the human detection sensor terminal 50a, the human detection sensor terminal that has transmitted the human detection signal based on the individual address added to the human detection signal. For the lighting fixtures 20a to 20d in the group G1 to which the group 50a belongs, a signal in which the group data of the group G1 is added to the system state information for turning on the lighting load 21 is transmitted from the power line communication unit 11, and the next room 81b A signal obtained by adding the group data of the group G1 to a system state signal for lighting the lighting load 21 is transmitted from the power line communication unit 11 to the lighting fixtures 20e to 20h in the group G2.

  At this time, in each lighting fixture 20a-20h, the control unit 25 compares the group data included in the signal received by the power line communication unit 24 with the group data set in the storage unit 23, and the group data matches. Stores the system state information from the controller 10 in the storage unit 23, and at the dimming level obtained by combining the individual lighting load information stored in the storage unit 23 and the system state information from the controller 10, the lighting circuit unit 22. The lighting load 21 is dimmed and controlled. Further, the human detection sensor terminals 50a and 50b installed in the rooms 81a and 81b do not detect a person for a certain period of time, and a human detection signal must be sent from the human detection sensor terminals 50a and 50b to the controller 10 for a certain period of time. For example, the controller 10 supplies a signal obtained by adding the group data of the groups G1 and G2 to the system state information for turning off the lighting load 21 for the lighting fixtures 20a to 20h in the groups G1 and G2, respectively. The lighting fixtures 20a to 20h in the groups G1 and G2 are turned off.

  In this way, in this system, the lighting fixtures 20a ... installed in each room 81a ... are made into one group, and on / off of the lighting fixtures 20a ... is controlled for each group. By turning on only the lighting fixtures 20a in the room to be entered and turning off the lighting fixtures in the other rooms, it is possible to save energy and to reduce the adverse effect of the illumination light on the exhibit. In addition, the controller 10 receives a human detection signal from the human detection sensor terminal 50a ... and sends a signal for turning on / off the lighting fixture 20a ... as system state information. 20a... May be turned on at a low dimming level, a human body detection signal from the human detection sensor terminal 50a... May be transmitted, and a signal for lighting the lighting fixtures 20a.

(Embodiment 5)
A fifth embodiment of the present invention will be described with reference to FIGS. FIG. 11 shows a system configuration diagram of the illumination system of this embodiment, and FIG. 10 shows a block diagram thereof. In this embodiment, a filter terminal that selectively cuts off a high-frequency current superimposed on the commercial power supply AC between the wiring duct 40 and the power line L1 with respect to the wiring duct 40 to which the luminaires 20a. 70 is attached, and the remote control receiving terminal 60 is detachably attached to the wiring duct 40.

  The remote control receiving terminal 60 includes a third power line communication unit (hereinafter abbreviated as a power line communication unit) 61 that transmits and receives a signal via the power line L1 in a power line carrier communication method in which a high frequency current is superimposed on the commercial power supply AC, A remote control signal receiving unit 62 that receives a setting signal of the luminaire 20a... Transmitted by a wireless signal composed of an optical signal such as an infrared ray from 65, and a control unit 63 that includes a microcomputer and controls the units 61 and 62. It consists of.

  The filter terminal 70 includes connection terminals T1 and T2 to which the power line L1 is connected as shown in FIG. 13, and connection terminals T3 and T4 that are electrically connected to a pair of conductive plates provided inside the wiring duct 40. 12 is attached to one end side in the longitudinal direction of the wiring duct 40 as shown in FIG. 12, and is electrically connected between the power line L1 and the pair of conductive plates of the wiring duct 40. The filter terminal 70 includes a first power line carrier communication circuit 71 that transmits and receives signals to and from the controller 10 via the power line L1 connected to the connection terminals T1 and T2, and connection terminals T3 and T4. A second power line carrier communication circuit 72 that transmits / receives a signal to / from the lighting fixture 20a... Or the remote control receiving terminal 60 through a conductive plate connected to the first and second power line carrier communications. A control circuit 73 that controls the operation of the circuits 71 and 72; a blocking filter 74 that is inserted between the connection terminals T1 and T2 and the connection terminals T3 and T4 and blocks the passage of the power line carrier signal superimposed on the power line L1; When one of the first or second power line carrier communication circuits 71 and 72 receives the power line carrier signal via the power line L1, the control circuit 73 receives the received signal. Only inner necessary signals are then transmitted to the power line L1 from the other, it has a function of selectively blocking the high frequency signal superimposed on the commercial power source AC.

  Here, the blocking filter 74 is a filter that is conventionally inserted into the main power line of the distribution board in a residential power line carrier communication system. The frequency currently recognized in the power line carrier communication system is in the range of 10 to 450 kHz, and the frequency is selected and used in each system. However, in other distribution boards (neighboring distribution boards for residential use) It is necessary to block this signal from flowing out from the main power line so that the power line carrier signal does not wrap around. Further, since the blocking filter 74 needs to pass a 50/60 Hz commercial frequency signal for power supply, it is generally composed of a low-pass filter that passes the commercial frequency. The blocking filter 74 may have any configuration as long as the commercial frequency can be passed and the power line carrier signal can be blocked.

  The filter terminal 70 includes a memory (not shown) that stores individual addresses of the lighting fixtures 20a connected to the wiring duct 40. And when lighting fixture 20a ... is attached to the wiring duct 40, the control circuit 73 of the filter terminal 70 relays the power line carrier signal transmitted / received between the controller 10 and lighting fixture 20a ..., embodiment. The individual address is set to the lighting fixtures 20a in the procedure as described in 1. However, the control circuit 73 stores the individual address of the lighting fixtures 20a in the memory while relaying the power line carrier signal. The individual addresses of the lighting fixtures 20a connected to the downstream side of the filter terminal 70 can be registered in the memory. When the filter terminal 70 receives the system state information from the controller 10 during the lighting control, the control circuit 73 stores the address data added to the system state information received by the first power line carrier communication circuit 71 in the memory. The received signal is sent out from the second power line carrier communication circuit 72 to the power line only when it matches the individual address stored in, and the luminaire 20a... Operates according to this system state information. Thus, since the filter terminal 70 selects the power line carrier signal based on the address data added to the power line carrier signal from the controller 10 and sends only the power line carrier signal that matches the selection condition to the appliance side. , Communication traffic can be reduced.

  When a plurality of lighting fixtures 20a are grouped into one group and lighting control of the lighting fixtures 20a is controlled for each group, group data is stored in the memory of the filter terminal 70 when a group address is set for the lighting fixtures 20a. Only when the group data included in the power line carrier signal from the controller 10 matches the group data stored in the memory, the control circuit 73 receives the second signal received by the first power line carrier communication circuit 71. The power line carrier communication circuit 72 may be sent to the power line.

  In this system, the remote control receiving terminal 60 is attached to the wiring duct 40, and setting information is set using the remote control setting device 65 for the lighting fixtures 20a attached to the wiring duct 40 to which the remote control receiving terminal 60 is attached. can do. Here, when the setting signal of the individual illumination load information is transmitted as a wireless signal from the remote control setting device 65, the remote control signal receiving unit 62 of the remote control receiving terminal 60 receives the setting signal transmitted as the wireless signal, and the control unit 63. Is sent from the power line communication unit 61 to the conductive plate of the wiring duct 40 as a power line carrier signal. At this time, the power line communication unit 24 of the lighting fixture 20a... Connected to the same wiring duct 40 as the remote control receiving terminal 60 receives the setting signal transmitted from the remote control receiving terminal 60 as the power line carrier signal, and the control unit 25 receives the setting signal. By storing the set signal in the storage unit 23, the individual lighting load information can be set in the lighting fixtures 20a. Since the filter terminal 70 is attached between the conductive plate of the wiring duct 40 and the power line L1, the filter terminal 70 blocks the power line carrier signal sent from the remote control receiving terminal 60 to the power line, so that the remote control The transmission range of the setting signal transmitted from the receiving terminal 60 can be limited to the wiring duct 40 to which the remote control receiving terminal 60 is attached. Further, when setting the individual illumination load information using the remote control receiving terminal 60, only the remote control receiving terminal 60 transmits the power line carrier signal to the conductive plate of the wiring duct 40, thereby reducing communication traffic. The responsiveness is improved and the setting operation can be performed in a short time.

  Further, in this system, since the remote control receiving terminal 60 that receives the wireless signal from the remote control setting device 65 is attached in the vicinity of the lighting fixtures 20a to be set, the light control level of the lighting fixtures 20a is set. Since the setting work can be performed near the lighting fixtures 20a, there is an advantage that the setting work is easy to perform. If the remote control receiving terminal 60 is slightly separated from the lighting fixtures 20a, it is affected by the infrared noise generated by the lighting load 21. It can be difficult. In addition, since it is not necessary to provide a remote control signal receiving unit for receiving a wireless signal in all of the lighting fixtures 20a, it is possible to reduce the cost of the lighting fixtures 20a. In this embodiment, wireless communication is performed between the remote control receiving terminal 60 and the remote control setting device 65 using an infrared signal, but wireless communication may be performed using an ultrasonic signal or a radio wave signal.

In this system, the filter terminal 70 attached to the wiring duct 40 holds the individual address information of the lighting fixtures 20a connected to the same wiring duct 40. It is possible to grasp at which position the individual lighting fixtures 20a... Are attached to the wiring duct 40 by taking in the information of the retained individual addresses. Therefore, when the controller 10 displays the set value of the dimming level of the lighting fixtures 20a connected to the power line L1 and the current lighting state together with the installation positions of the lighting fixtures 20a ..., for example, in the installation example of FIG. The position of the wiring duct can be specified with an easy-to-understand expression such as “the wiring duct on the south side of the room 81a”, and the display of the installation position can be easily understood.

  For example, as described in the fourth embodiment, when a plurality of lighting fixtures 20a is divided into a plurality of groups G1, and the lighting state of the lighting fixtures 20a is controlled for each group, it belongs to one of the groups G1. When the dimming level of the lighting fixtures 20a ... is changed, the base lighting fixtures 90a ... installed in the same area are linked and controlled in accordance with preset contents.

  Here, the interlocking control operation of the base lighting fixture 90a ... is set in advance. For example, when an exhibit is illuminated with a lighting fixture 20a ... composed of a spotlight in an art museum or a museum, the exhibit is heated by the illumination heat. In order to prevent the deterioration, control is performed to lower the dimming level of the lighting fixtures 20a ... when there is no person, but the exhibits are conspicuous when the dimming level of the lighting fixtures 20a ... is lowered. In order to prevent the loss, the interlocking relationship is set so that the dimming level of the base lighting fixtures 90a. And the control part 13 of the controller 10 calculates the average illumination intensity of the lighting fixtures 20a ... in the same area at the time of illumination control, and according to the average illumination intensity of the lighting fixtures 20a ... when the light control level of the lighting fixtures 20a ... is lowered. The dimming level of the base lighting fixtures 90a in the same area is lowered. In addition, in order to raise the whole dimming level when the dimming level of the lighting fixtures 20a ... is lowered, interlocking control may be performed so that the dimming level of the base lighting fixtures 90a ... is raised simultaneously. If a human detection sensor terminal is added, the dimming control of the area in which the person is detected in accordance with a preset route and the lighting fixtures 20a in the next area together with the base lighting fixture 90a in the same manner as in the fourth embodiment. By performing the interlock control of the base lighting fixtures 90a ..., it is possible to perform the dimming control according to the priority set by the setter, such as energy saving and rendering performance.
