Description

  The present invention relates to a power supply device for a blackout lamp, a blackout lamp device, and a blackout lamp control system.

  In general, in a power failure lamp device, a storage battery is charged by a charging circuit during normal times when AC power is supplied, and a light source is turned on using the AC power as a power source, and a light source is turned on using the storage battery as a power source during a power failure when AC power is not supplied. The Such a blackout lamp device requires periodic inspection, and in this inspection, a light source is intentionally turned on using a storage battery as a power source. Conventionally, it has been necessary to manually operate the blackout lamp device such as pressing a switch attached to the main body of the blackout lamp device, and the work efficiency is low. Therefore, a configuration using communication for inspection has been proposed.

  For example, Patent Document 1 discloses that an emergency lighting device that always lights an emergency light with a commercial power source and lights an emergency light with a storage battery as a power source during a power failure, receives visible light from a remote control transmitter, and receives the visible light. The structure which processes a signal and lights an emergency light by using a storage battery as a power supply is disclosed. Further, Patent Document 2 discloses an inspection in which a signal is transmitted and received between the communication unit of the guide light automatic inspection device and the guide light control monitoring panel connected to the network, and the lamp is lit with an emergency power source for a predetermined time or more. A configuration for performing and controlling and monitoring the apparatus is disclosed. Further, in Patent Document 3, in a lighting system in which a plurality of lighting fixtures are connected to control means via communication means, the control means switches each lighting fixture from a normal mode to an inspection mode according to a schedule, and a battery is used for a specified time. A configuration for lighting the lamp is disclosed.

The power supply devices for blackout lamps 2-1 to 2-n are each connected to an AC power supply AC such as a commercial power supply, and are connected to the DALI master device 4 via a two-wire communication line L. Although the AC power supply AC is illustrated as an individual power supply in each figure, each AC power supply AC may be of the same system or a different system. Each of the power supply devices for blackout lights 2-1 to 2-n has the same circuit configuration. In the following description, the power supply devices for blackout lights 2-1 to 2-n are generically referred to, or one of them is referred to as the power supply device for blackout lights 2, and the LED arrays 3-1 to 3-n are generically named.

The LED array 3 is supplied. Further, the blackout lamp in the present disclosure is an emergency light, a guide light, and the like, and not only the light source is turned on when AC power AC is supplied (hereinafter referred to as “normal time”), but also AC power AC Is a lighting device having a function of continuing to turn on the light source for a certain period of time even when the light is interrupted (hereinafter referred to as “power failure”).

  The charging circuit 10 includes a diode bridge DB, a capacitor 11, a switching element 12 (hereinafter referred to as “FET 12”), a transformer 13, a diode 14, a capacitor 15, and a driver 16, and constitutes an insulating flyback converter. This flyback converter is preferably a power factor improving step-up converter in which the capacitance of the capacitor 11 on the input side is smaller than the capacitance of the capacitor 15 on the output side. ). The driver 16 receives an ON / OFF signal input from the control unit 50, and the FET 12 is PWM-driven by the driver 16. In a state where the input power is supplied and the driver 16 is switching the FET 12, the charging circuit 10 performs full-wave rectification and boosting of the input power to charge the storage battery 20 and supply the input voltage of the output circuit 40. The charging circuit 10 functions as a power factor correction circuit for the power supply device 2 for blackout lights and a charging circuit for the storage battery 20.

  The detection circuit 30 includes a voltage detection circuit 31 and a current detection circuit 32.

  The output circuit 40 is a DC / DC converter such as a step-down chopper circuit (buck converter) or a flyback converter. The output circuit 40 performs constant current control using the output voltage of the charging circuit 10 or the voltage of the storage battery 20 as a power source, and supplies a constant LED current to the LED array 3. Therefore, the LED array 3 is lit at a constant current by the output circuit 40 using the AC power supply AC as a power source during the normal operation of the charging circuit 10 (hereinafter referred to as “normal lighting”), and the storage battery 20 is powered when the output of the charging circuit is stopped. As shown in FIG.

  The control unit 50 includes a reception unit 51, an operation switching unit 52, a data signal generation unit 53, and a transmission unit 54. For example, the operation switching unit 52 and the data signal generation unit 53 may be a part of the CPU of the microcomputer. As an outline, the control unit 50 performs DALI communication with the DALI master device 4 by half-duplex communication, and controls output execution / output stop of the charging circuit 10.

  The receiving unit 51 receives a DALI format control signal (Manchester encoded signal) from the DALI master device 4 via the communication line L, decodes the received control signal, and outputs a Forward frame compliant with the DALI standard. .

  FIG. 2 shows the structure of the Forward frame. The Forward frame includes a start bit (1 bit), an address bit Y, A5 to A0 and S (8 bits), data bits D7 to D0 (8 bits), and a stop bit (2 bits). Address bits Y and S are bits used for a specific command, and 64 addresses can be set by address bits A5 to A0. In other words, 64 blackout power supply devices 2 can be connected to one DALI master device 4.

  The operation switching unit 52 identifies the command from the data bits of the control signal when the address indicated by the address bit of the decoded control signal is the address of the power supply device 2 for the blackout lamp. When the identified command is an inspection command, the operation switching unit 52 outputs an off signal to the driver 16 to stop the switching of the FET 12 and stop the output of the charging circuit 10. Further, when the identified command is an inspection end command, the operation switching unit 52 outputs an ON signal to the driver 16 to start switching of the FET 12, and resumes and maintains the output of the charging circuit 10. Note that the operation switching unit 52 maintains the latest operation state (output execution or output stop) of the charging circuit 10 when the control signal is not received.

  Similar to the operation switching unit 52, the data signal generation unit 53 identifies a command from the data bits of the control signal when the address indicated by the address bit of the decoded control signal is the address of the power supply device 2 for the blackout lamp . When the identified command is an inspection command or a monitor command, the data signal generation unit 53 outputs a data signal indicating at least one of the detection voltage and the detection current input from the detection circuit 30 to a Backward frame based on the DALI standard. Generate using.

  As shown in FIG. 3, the Backward frame includes a start bit (1 bit), data bits D7 to D0 (8 bits), and a stop bit (2 bits). That is, the data signal generation unit 53 generates a DALI-format data signal indicating one or both of the detection voltage and the detection current (self-device address as necessary) using the data bit.

  The transmission unit 54 performs Manchester encoding of the generated data signal, sends the encoded data signal to the communication line L, and transmits it to the DALI master device 4.

  The DALI master device 4 includes an input interface 60, a control signal generation unit 61, a transmission unit 62, a reception unit 63, an information generation unit 64, and a display unit 65, and constitutes a control panel, for example. The display unit 65 is a liquid crystal display screen or the like. The input interface 60 is an operation unit that receives user input, and may be a display screen when the display unit 65 is a touch panel.

  The control signal generation unit 61 generates a control signal (Forward frame) indicating each operation command of the power supply device 2 for the blackout lamp based on the user input.

  The transmission unit 62 performs Manchester encoding of the control signal generated by the control signal generation unit 61, transmits the control signal to the communication line L, and transmits the control signal to each power supply device 2 for the blackout lamp.

  The receiving unit 63 receives a data signal (Manchester encoded signal) from each blackout power supply device 2 via the communication line L, decodes the received data signal, and generates a Backward frame.

  The information generation unit 64 generates state information indicating the state of the storage battery 20 of each power source device 2 for blackout lamps (normal / abnormal, degree of deterioration, progress of life, etc.) from the decoded data signal. Information is displayed on the display unit 65. The state information may indicate not only the state of the storage battery 20 but also the state of the power source device 2 for the blackout lamp. In addition, when the transmission address or data signal acquired from the control signal generation unit 61 includes an address, the information generation unit 64 may cause the display unit 65 to display the address information together with the state information based on the address. it can.

-Operation example of individual inspection The operation | movement in the case of performing the individual inspection of the power supply apparatus 2-k (1 <= k <= n) for a blackout lamp at normal time is demonstrated. In the DALI master device 4, an inspection command is input by the user via the input interface 60. The control signal generation unit 61 generates a control signal (Forward frame) indicating an inspection start command. For example, the control signal generation unit 61 sets the address bit to an address corresponding to the power supply device 2-k for the power lamp, and sets the data bit to a predefined inspection command value (command). And the transmission part 62 transmits this control signal to the power supply apparatus 2-k for blackout lamps.

  In response to this, in the control unit 50 of the power supply device 2-k for the blackout lamp, the operation switching unit 52 charges the off signal for the inspection operation in accordance with the control signal (inspection command) received by the receiving unit 51. Output to the circuit 10. The switching of the FET 12 by the driver 16 is stopped by the off signal. Therefore, in the power supply device 2-k for the power failure lamp, a pseudo power failure state is formed even when the AC power supply AC is supplied, and the LED array 3 is started to be turned on by the output circuit 40 using the storage battery 20 as a power source. . Thereby, the user can confirm whether the power supply device 2-k for blackout lights and the LED array 3 are turned on (normal) / off (abnormal).

  The data signal generation unit 53 generates a data signal (Backward frame) indicating at least one of the detection voltage and the detection current detected by the detection circuit 30 in response to the inspection command, and the transmission unit 54 transmits the data signal to the DALI master. Transmit to device 4. In the DALI master device 4, based on the data signal received by the receiving unit 63, the information generating unit 64 obtains status information regarding the storage battery 20 of each blackout power supply device 2-k or the blackout power supply device 2-k itself. It is displayed on the display unit 65. Moreover, the information generation part 64 can acquire a transmission address from the control signal generation part 61, and can also display address information on the display part 65 with status information based on a transmission address. Thereby, the individual inspection of each blackout lamp device can be performed not at the installation location of each blackout lamp device but at the location of the DALI master device 4, and a detailed and efficient inspection work can be performed.

  The status information includes, for example, whether or not the detected voltage is maintained at a predetermined voltage value or more for a specified time or more after the start of the inspection operation, or whether or not the detected current is maintained at a predetermined current value or more for a specified time or more. It only needs to indicate a determination. The predetermined voltage value is a value corresponding to a storage battery voltage at which the output voltage of the output circuit 40 is equal to or higher than the forward voltage Vf of the LED array 3. The predetermined current value is a value corresponding to a necessary LED current. Note that the specified time is 10 minutes, 20 minutes, 30 minutes, 60 minutes, or the like determined by the standard. Alternatively, after the start of the inspection operation, the time required for the detected voltage or detected current to become less than the predetermined voltage value or the predetermined current value may be adopted as the state information.

  Further, when the storage battery 20 is deteriorated and its capacity is reduced, the discharge rate is increased. Therefore, when the rate of decrease in the detected voltage indicated by the data signal from the power supply device 2-k for the blackout lamp exceeds the specified value, the storage battery 20 of the power supply device 2-k for the blackout lamp has deteriorated. It may indicate that. Further, the state information may indicate the deterioration level of the storage battery 20 or the progress of life according to the degree of the decrease rate of the detection voltage.

  At the time of an inspection end command (timing determined by a user input, a timer or a program), the control signal generation unit 61 generates a control signal indicating an inspection end command, and the transmission unit 62 transmits this control signal to the power supply for the blackout lamp Transmit to device 2-k. In the control unit 50 of the power supply device 2-k for the blackout lamp, the operation switching unit 52 outputs an ON signal for the normal output operation based on the received control signal. The switching of the FET 12 by the driver 16 is started by the ON signal, and the normal lighting of the power supply device 2-k for the power lamp is resumed and maintained.

  Further, when the storage battery 20 is deteriorated and its capacity is reduced, the charging speed is increased. Therefore, immediately after resuming normal lighting, if the detection voltage increase rate or the charging current decrease rate indicated by the data signal from the power supply device 2-k for the power failure light exceeds the specified value, the status information is for the power failure light. It may indicate that the storage battery 20 of the power supply device 2-k has deteriorated. Further, the state information may indicate the deterioration level of the storage battery 20 or the progress of life according to the degree of the detection voltage increase rate or the charging current decrease rate.

  In this example, it is assumed that the data signal generated by the data signal generation unit 53 indicates a detected voltage value or a detected current value. In other words, it is assumed that the information generation unit 64 performs various calculations or determinations based on each detection value. On the other hand, the data signal generation unit 53 may generate a calculation result based on the detected voltage value or the detected current value or a determination result related to the storage battery 20 or the power supply device 2 for the blackout lamp as a data signal. This calculation result is, for example, the estimated capacity of the storage battery 20 calculated from the detected voltage change amount, the time required for this voltage change, and the detected current value (constant discharge current by constant current control). Further, the determination result may be the above pass / fail determination result, or whether the storage battery 20 is normal or abnormal based on the discharge rate, the charge rate, the estimated capacity, the deterioration level, the progress of life, etc. Also good.

-Operation example of simultaneous inspection Next, the operation | movement in the case of performing the simultaneous inspection of the power supply devices 2-1 to 2-n for blackout lights at the normal time is demonstrated. In the DALI master device 4, a simultaneous inspection command is input by the user via the input interface 60. The control signal generation unit 61 generates a control signal (Forward frame) indicating a simultaneous inspection start command. For example, the control signal generation unit 61 sets an address bit to a broadcast address (11111110 or 11111111), and sets a data bit to a predefined inspection command value (command). And the transmission part 62 transmits this control signal to each power supply device 2 for blackout lights.

  In response to this, in the control unit 50 of each power supply device 2 for blackout lamps, the operation switching unit 52 supplies an off signal for the inspection operation based on the control signal (inspection command) received by the receiving unit 51 to the charging circuit. 10 is output. The switching of the FET 12 by the driver 16 is stopped by the off signal. Therefore, in each power supply device 2 for blackout lamps, a pseudo power failure state is formed in a state where the AC power supply AC is supplied, and lighting of the LED array 3 by the output circuit 40 using the storage battery 20 as a power supply is started. Thereby, the user can confirm whether the LED array 3 of each power supply device 2 for blackout lights is on (normal) / unlit (abnormal).

  The data signal generation unit 53 generates a data signal (Backward frame) based on at least one of the detection voltage and the detection current detected by the detection circuit 30 in response to the inspection command, and the transmission unit 54 transmits the data signal to the DALI master. Transmit to device 4. In the case of simultaneous inspection, each data signal includes the address of each of the power supply devices for blackout lamps 2-1 to 2-n. In this case, a predetermined bit (maximum 6 bits corresponding to the value of n) of the data bits D7 to D0 of the Backward frame indicates an address, and the remaining bits are for the storage battery 20 of each power supply device 2 for power failure lights or for the power failure light thereof. The state of the power supply device 2 itself is shown.

  Information indicated by the remaining bits is appropriately determined according to the number of bits. When the number of remaining bits is relatively large (when n is relatively small), the detected voltage value or the detected current value can be included in the remaining bits as in the case of the individual inspection described above. On the other hand, when the number of remaining bits is relatively small (when n is relatively large), the data signal generation unit 53 makes a determination on the storage battery 20 or the power supply device 2 for the power lamp, and the determination result is included in the remaining bits. . This determination result may be the above-mentioned pass / fail determination result, or whether the storage battery 20 is normal or abnormal based on calculation results such as discharge rate, charge rate, estimated capacity, deterioration level, progress of life, etc. May be. If it is such a determination result, it can be expressed by data of 1 to 2 bits.

  In the DALI master device 4, based on the data signal received by the receiving unit 63, the information generating unit 64 causes the display unit 65 to display the address information and status information of each blackout lamp power supply device 2. Thereby, the inspection and confirmation work of the blackout lamp device can be performed not at the installation place of each blackout lamp device but at the place of the DALI master device 4, and the inspection work becomes more efficient.

  At the time of inspection end command (timing determined by user input, timer, or program), the control signal generation unit 61 generates a control signal indicating a command to end simultaneous inspection, and the transmission unit 62 uses this control signal for each blackout lamp. Transmit to the power supply 2. In the control unit 50 of each power supply for blackout lamp 2, the operation switching unit 52 outputs an ON signal for normal output operation based on the received control signal. The switching of the FET 12 by the driver 16 is started by the ON signal, and the normal lighting of each power supply device 2 for the blackout lamp is resumed and maintained.

-Operational Example of Monitor Process Next, the monitor process will be described. Even when the normal lighting is performed as well as during the inspection, a data signal indicating the detected voltage or the detected current is generated in the control unit 50, and the monitoring process in which the status information is displayed on the display unit 65 in the DALI master device 4 is applied. Good. As an outline, when the control signal indicates a monitor command, the operation switching unit 52 maintains the output operation of the charging circuit 10, and the data signal generating unit 53 performs data based on the DALI communication standard based on the detected voltage or the detected current. Generate a signal. The monitor process includes an individual monitor process and a simultaneous monitor process.

  In the case of the individual monitor process, the control signal generation unit 61 sets the address bit of the Forward frame to an address corresponding to the power supply device 2-k for the power lamp, and sets the data bit to a predefined monitor command value (command). Set. And the transmission part 62 transmits this control signal to the power supply apparatus 2-k for blackout lamps.

  In response to this, the data signal generation unit 53 of the power supply device 2-k for the blackout lamp detects the detection voltage and the detection current detected by the detection circuit 30 based on the control signal (monitor command) received by the reception unit 51. A data signal (Backward frame) indicating at least one of them is generated, and the transmission unit 54 transmits this data signal to the DALI master device 4. Note that the operation switching unit 52 does not react to the monitor command and maintains the ON signal, and thus the charging circuit 10 maintains the output operation. In the DALI master device 4, the information generation unit 64 causes the display unit 65 to display address information and status information based on the address acquired from the control signal generation unit 61 and the data signal received by the reception unit 63. .

  In the case of simultaneous monitoring processing, the control signal generation unit 61 sets the address bit of the Forward frame as a broadcast address, and sets the data bit as a value (command) of a predefined monitor command. And the transmission part 62 transmits this control signal to each power supply device 2 for blackout lights.

  In response to this, the data signal generation unit 53 of each blackout lamp power supply device 2 indicates at least one of the detection voltage and the detection current detected by the detection circuit 30 based on the monitor command received by the reception unit 51. A data signal (Backward frame) is generated, and the transmission unit 54 transmits the data signal to the DALI master device 4. Note that the operation switching unit 52 does not react to the monitor command and maintains the ON signal, and thus the charging circuit 10 maintains the output operation. In the DALI master device 4, based on the data signal received by the receiving unit 63, the information generating unit 64 causes the display unit 65 to display address information and state information.

  By the monitoring process as described above, the user can recognize at an early stage an abnormality in the detected voltage or detected current, that is, an abnormality in the storage battery 20, and further an abnormality in the charging circuit 10, the output circuit 40, or the LED array 3.

  Moreover, in each said operation example, the structure by which individual or simultaneous inspection processing or individual or simultaneous monitoring processing was performed with respect to the power supply devices 2-1 to 2-n for blackout lights was shown. On the other hand, by using the group address function of DALI communication, the inspection process or the monitor process for each group (up to 16 groups) of the power supply device 2 for the blackout lamp may be executed by a predetermined setting of the address bits.

  As described above, the blackout lamp control system 1 of the present embodiment includes the blackout power supply device 2, the LED array 3, and the DALI master device 4. And the power supply device 2 for blackout lamps supplies electric power to the LED array 3 by using the storage battery 20, the charging circuit 10 to which the input power is supplied and charging the storage battery 20, and the output voltage of the charging circuit 10 or the storage battery 20 as a power source. The output circuit 40 includes a receiving unit 51 that receives a control signal that conforms to the DALI communication standard from the communication line L, and an operation switching unit 52 that stops the output of the charging circuit 10 when the control signal indicates an inspection command.

  That is, in the power supply device 2 for blackout lamps, when a control signal conforming to the DALI communication standard is received and the control signal is an inspection command, the output of the charging circuit 10 is stopped and lighting with the storage battery 20 as a power source is performed.

As described above, the configuration in which the control signal according to DALI, which is a general-purpose communication standard, is used for carrying out the inspection operation, so that the blackout lamp control system 1, the blackout lamp power supply device 2 and the blackout are easy to install and expand. A lamp device is realized.

  Furthermore, a voltage detection circuit 31 that detects the voltage of the storage battery 20 as a detection voltage or a current detection circuit 32 that detects a charging current or discharge current of the storage battery 20 as a detection current is provided, and the DALI communication standard is based on the detection voltage or detection current. Is provided with a data signal generation unit 53 that generates a data signal that complies with the standard, and a transmission unit 54 that transmits the data signal to the communication line L. Thereby, since the inspection work is performed using the two-way communication by DALI, the inspection work becomes more efficient with a simple configuration.

<Second Embodiment>
In the first embodiment, the configuration in which the slave device controlled by the DALI master device 4 is only the power supply device for the blackout lamp is shown. However, in the present embodiment, other types of power supply devices for illumination are also slave devices. The structure which becomes.

  In FIG. 4, the block diagram of the blackout lamp system 1 of this embodiment is shown. In this embodiment, the same code | symbol is attached | subjected to the structure similar to 1st Embodiment, and the overlapping description is abbreviate | omitted. As shown in FIG. 4, power failure light power supply devices 2-1 to 2-x, downlight power supply devices 5-1 to 5-y, and guide light power supply devices 6-1 to the DALI master device 4. 6-z is connected. Since the number of control target devices that can be connected to one DLAI master is 64, x + y + z ≦ 64. The downlight power supply devices 5-1 to 5-y and the guide light power supply devices 6-1 to 6-z are also collectively referred to as illumination power supply devices.

  Each of the downlight power supply devices 5-1 to 5-y includes a downlight Ld, a lighting circuit 70, and a control unit 75. The lighting circuit 70 generates an output current for downlight from the input power supply and supplies the output current to the downlight Ld. The control unit 75 receives a DALI-format control signal from the DALI master device 4 and controls the operation of the lighting circuit 70 in accordance with the control signal. Each of the guide lamp power supply devices 6-1 to 6-z includes a guide lamp Le, a lighting circuit 80, and a control unit 85. The lighting circuit 80 generates an output current for the guide lamp from the input power supply and supplies the output current to the guide lamp Le. The control unit 85 receives a DALI format control signal from the DALI master device 4 and controls the operation of the lighting circuit 80 according to the control signal. For example, the control unit 75 controls the lighting circuit 70 so as to perform dimming control of the downlight Ld according to the control signal, and the control unit 85 performs an inspection operation (for example, lighting and extinguishing of the guide light Le) according to the control signal. The lighting circuit 80 is controlled to execute the above.

  In the case of using the group address function, for example, a subset (some or all of the power supply devices for power lamps 2-1 to 2-x) is the group of the group address 1. Similarly, a subset of the downlight power supply devices 5-1 to 5-y constitutes a group of group address 2, and a subset of the guide light power supply devices 6-1 to 6-z defines a group of group address 3. Shall be composed.

  The group control is specified by setting the address bits Y to A4 of the Forward frame of the DALI signal to “100”, and the group address is specified by the address bits A3 to A0. Note that the address bit S is a bit related to command selection, and in this example, is assumed to be “0” (DirectArcPowerControl command). For example, the DALI master device 4 sets the address bits to “10000010” when controlling a subset of the power supply devices for blackout lamps 2-1 to 2-x of the group address 1. Similarly, when the DALI master device 4 controls a subset of the downlight power supply devices 5-1 to 5-y of the group address 2, the address bit is set to “10000100” and the guide light of the group address 3 is set. When controlling a subset of the power supply devices 6-1 to 6-z, the address bits are set to “10000110”.

  When the individual address function is used, the address bits of the Forward frame of the DALI signal indicate that the power supply device for the blackout lamp 2-1 to 2-x, the power supply device for the downlight 5-1 to 5-y, and the power supply for the guide light It is set to show each of the devices 6-1 to 6-z.

  The inspection process of the power supply devices for blackout lamps 2-1 to 2-x when the group address is used is substantially the same as the simultaneous inspection process described above in the first embodiment. In addition, the inspection process of each power source 2 for blackout lights when the individual address is used is the same as the individual inspection process described in the first embodiment.

  As described above, the blackout lamp control system 1 according to the present embodiment has a group address 1 and includes a group including at least one of the blackout power supply devices 2-1 to 2-x, and a group address 2/3. A group including at least one of the lighting power supply devices 5-1 to 5-y / 6-1 to 6-z, and the DALI master device 4. The DALI master device 4 is configured to transmit individual control signals conforming to the DALI communication standard to the group address 1 and the group address 2/3, respectively. The DALI master device 4 is configured to transmit a control signal indicating an individual command conforming to the DALI communication standard to the individual address of each power supply device.

  In this way, it is possible to perform integrated or individual control of the power supply device 2 for the power lamp and the other power supply device for illumination using the group address function or the individual address function in DALI communication. Thereby, the blackout lamp control system 1 with high ease of introduction and expandability is realized.

<Third Embodiment>
In the first embodiment, a configuration using a communication signal compliant with the DALI standard is shown. However, in the present embodiment, a configuration in which a communication signal compliant with the DMX512 standard is applied is shown.

  FIG. 5 shows a block diagram of the blackout light control system 1 according to the present embodiment. In this embodiment, the same code | symbol is attached | subjected to the structure similar to 1st Embodiment, and the overlapping description is abbreviate | omitted. In this embodiment, a DMX master device 7 is provided instead of the DALI master device 4. The power supply devices for blackout lamps 2-1 to 2-n are each connected to an AC power supply AC such as a commercial power supply, and daisy chain connected to the DMX master device 7 via a three-wire communication line Lx.

  Since the DMX 512 is for one-way communication, a data signal is not transmitted from the power supply 2 for the power lamp 2 to the DMX master device 7. Therefore, in the power supply device 2 for the blackout lamp, the detection circuit 30, the data signal generation unit 53, and the transmission unit 54 related to the data signal as in the first embodiment are not provided. In addition, the control unit 50 includes an input unit 55 for receiving and acquiring a signal from the signal line Lx and transferring the signal to the downstream power supply 2 for the power lamp 2.

  A control signal by the DMX 512 from the DMX master device 7 is composed of a start sequence slot and first to 512th data slots (that is, 513 slots), and each slot consists of 8 bits. Between the DMX master device 7 and each power source device 2 for blackout lights, an address is set in advance as to which power slot 2 corresponds to which power source device 2 for blackout lights. Therefore, the operation switching unit 52 of each blackout lamp power supply device 2 counts the number of bytes from the start of the control signal received by the input unit 55, extracts only the slot corresponding to its own address, and controls the control signal. Identifies the command indicated by

  The DMX master device 7 includes an input interface 90, a control signal generation unit 91, and a transmission unit 92, and constitutes a control panel, for example. The input interface 90 is an operation unit that receives user input.

  The control signal generation unit 91 generates a control signal indicating each operation command of the power supply device 2 for a blackout lamp based on a user input. The transmission unit 92 encodes the control signal, sends the control signal to the communication line Lx, and transmits the control signal to each power source device 2 for blackout lamps.

  When the identified command is an inspection command, the operation switching unit 52 outputs an off signal to the driver 16 to stop the switching of the FET 12 and stop the output of the charging circuit 10. Further, when the identified command is a normal lighting command, the operation switching unit 52 outputs an ON signal to the driver 16 to start switching of the FET 12, and resumes and maintains the output of the charging circuit 10.

  As described above, the power supply device 2 for blackout lamp according to the present embodiment supplies the storage battery 20, the charging circuit 10 that is supplied with input power to charge the storage battery 20, and the output voltage of the charging circuit 10 or the voltage of the storage battery 20. Output circuit 40 for supplying power to LED array 3, receiver 51 for receiving a control signal based on the DMX512 communication standard from communication line Lx, and stopping output of charging circuit 10 when the control signal indicates an inspection command And an operation switching unit 52 to be operated.

  That is, in the power supply device 2 for blackout lamps, when a control signal conforming to the DMX512 communication standard is received and the control signal is an inspection command, the output of the charging circuit 10 is stopped and the storage battery 20 is turned on. As a result, the control signal according to DMX512, which is a general-purpose communication standard, is used for carrying out the inspection operation, so that the blackout lamp control system 1, the blackout power supply device 2 and the blackout lamp are easy to introduce and expand. A device is realized.
