Description

  The present invention relates to a power supply terminal block capable of notifying that an electrical device has reached an energization time assumed in advance, and a lighting fixture including the power supply terminal block.

  Conventionally, in order to notify that the luminaire has reached the end of its life, the elapsed time from the start of use when the luminaire is first connected to the commercial AC power source is measured, and this measurement time is preset. The life discriminating means determines whether or not the predetermined aging energization time has been reached, and when the life discriminating means determines that the predetermined aging energization time has been reached, the life notification means notifies the user of the discrimination result information. The technique which performs is known (for example, refer patent document 1).

  The life notification means in this technology is a visual notice, that is, a case where an LCD panel or the like that performs a display operation without using a regular lamp of a lighting fixture is used, and a notice that appeals to an auditory, that is, a speaker is used. There is.

Moreover, the lighting fixture is provided with the power terminal block which relays a power wire and wiring in a fixture. In general, a power supply terminal block has a pair of positive connection terminals for positive and negative electrodes and a ground terminal if necessary, and a plurality of wire insertion holes corresponding to these terminals. Provided. The wire inserted into the housing through the wire insertion hole is inserted between the wire receiving portion of the quick-connection terminal facing the insertion location and the elastically deformable locking piece diagonally opposed to the wire receiving portion. By this, it is clamped by these electric wire receiving parts and a locking piece, and is connected mechanically and electrically (for example, refer patent document 2).
Japanese Patent Laying-Open No. 2006-236713 (paragraphs 0012-0044, FIGS. 1 to 11) JP 2001-283948 A (paragraphs 0025-0067, FIGS. 1 to 12)

  The control part which makes the lifetime determination means of patent document 1 is formed as a main component, and this control part is comprised separately from the electronic ballast which makes a lighting circuit. For this reason, it is necessary to fix the control unit that constitutes the determination means at an appropriate location and to perform wiring processing for supplying power to the control unit. Such a situation is the same even when a life notification control unit is incorporated in a lighting fixture using an incandescent lamp that can be lit without using an electronic ballast.

  By the way, since the inverter type electronic ballast includes a circuit board on which a plurality of electronic components are mounted, it is conceivable to incorporate a control unit for life notification using this circuit board. Electronic components of the electronic ballast include components that generate a large amount of heat, such as a transformer. For this reason, when the control unit for life notification is incorporated in the electronic ballast as described above, the temperature of the built-in control unit is likely to rise due to the heat generating parts of the electronic ballast, so that the deterioration of the control unit is promoted. . As a result, there is a possibility that the control unit that constitutes the life determining means deteriorates before reaching the preset aging energization time, and when the aging energization time is reached, the notification function cannot be exhibited.

  Therefore, there is a need for a technique that eliminates the need for mounting the control unit for the life notification and obtains an advantage in wiring processing in such a manner. In addition, as described above, the configuration in which the control unit for life notification is incorporated in the electronic ballast cannot be applied to a lighting fixture that does not require the electronic ballast, such as a lighting fixture using an incandescent lamp.

  On the other hand, although it is desired that the luminaire installed on the ceiling is promoted to be thin, Patent Document 1 does not include a description of a specific arrangement of the control unit that constitutes the life determination means. It is also unclear whether this arrangement is suitable for promoting thinning of the lighting fixture.

  In addition, the conventional power terminal block described in Patent Document 2 is specialized in relaying with power supply wires, for example, in-instrument wiring (load wires) such as lead-in power wires from the ceiling. It is not configured to function.

  When a new function is added to the power supply terminal block, it is desired to consider that the power supply terminal block is not thickened by a device for performing the function. If a device with a new function is incorporated in the power supply terminal block without taking such considerations into consideration, it may be a factor that hinders the thinning of the electrical equipment such as lighting equipment equipped with the power supply terminal block. Can be considered.

  It is an object of the present invention to provide a notification device that reliably notifies that a predetermined energization time has been reached at a predetermined time, and saves the trouble of installation and wiring processing of the notification device, and the notification device increases the thickness. It is an object of the present invention to provide a power supply terminal block that does not become necessary, and a lighting fixture including the power supply terminal block.

  A power supply terminal block according to a first aspect of the present invention is a terminal block case having a supply positive electrode insertion hole, a supply negative electrode insertion hole, a load positive electrode insertion hole, and a load negative electrode insertion hole; Connected to the electric wire inserted into the terminal block case through the positive electrode wire insertion hole for supply, and the electric wire inserted into the terminal block case through the positive electrode wire insertion hole for load A positive connection terminal for a positive electrode; an electric wire that is arranged in the terminal block case in parallel with the positive connection terminal for a positive electrode and is inserted into the terminal block case through the negative electrode electric wire insertion hole for supply; and the load A negative electrode quick connection terminal to which an electric wire inserted into the terminal block case is connected through the negative electrode electric wire insertion hole; a circuit board electrically connected to both the positive electrode and negative electrode fast connection terminals; Mounted on the circuit board from the start of energization A measurement unit that measures overtime, and a sound output unit that informs by sound that the aging energization time has been reached based on the measurement unit measuring the aging energization time that is mounted on the circuit board and is assumed in advance. And a notification device built in the terminal block case at a side of the two-speed connection terminal.

  In the present invention, among the measuring units that measure the elapsed time from the start of energization, the “energization start” means that an electrical device equipped with the power terminal block of the present invention, such as a lighting fixture, is energized first after its manufacture. The “elapsed time” indicates the cumulative energization time from the start of energization. The “measurement unit” preferably has a microcomputer as a main component when the notification device has a microcomputer mounted on a circuit board, and specifically, a timer for counting clock pulses of the microcomputer. It can be used as a measuring unit, and thus the elapsed time can be counted.

  In the present invention, the presumed aged energization time is preferably the degree of progress of deterioration of each part of an electric device such as a lighting device with the use over time until the time is reached. It refers to the time assumed to progress to a certain extent.

  In the present invention, the notifying means for notifying by sound amplifies the synthesized sound formed by the speech synthesizing means made of LSI mounted on the circuit board in addition to the buzzer that sounds, and outputs the amplified signal It may be composed of a speaker or the like. Here, the “voice” may be a sound perceived by the user as a language, or may be a sound perceived by the user as an alarm sound that does not make sense as a language.

  In the present invention, the "notification device located in the side of the double speed connection terminal and built in the terminal block case" means that the notification device is arranged in the terminal block case in the arrangement direction of the double speed connection terminals or in this alignment direction. It means that they are arranged in parallel.

  In the power supply terminal block of the invention according to claim 1, since the notification device is built in the terminal block case and connected to the quick connection terminals for the positive electrode and the negative electrode, compared with the case where the notification device is installed alone. It can be installed together with the power terminal block, and the labor for mounting the notification device can be saved, and the trouble of wiring processing for supplying power to the notification device can also be saved.

  And since the notification device is arranged on the side of both speed connection terminals in the terminal block case, the notification device overlaps the thickness direction of the terminal block case with respect to both speed connection terminals, and the thickness of the power terminal block is increased. There is no. For this reason, when accelerating the thinning of an electric device such as a lighting fixture provided with the power supply terminal block of the present invention, the power supply terminal block of the present invention can be a factor that does not hinder the thinning of the electric device.

  In addition, when the measurement unit of the notification device measures that the pre-established aging energization time has been reached, the sound output unit is operated based on the measurement to release the sound to the outside. Thereby, it can be notified that the energization time assumed in advance has been reached. If the electrical equipment provided with the power terminal block, for example, a lighting fixture has an electronic ballast, the power terminal block is arranged outside the electronic ballast, so that the notification device deteriorates due to the heat of the electronic ballast. However, there is no fear that the operation reliability is lowered. Therefore, when the notification device reaches a predetermined time period, that is, when the pre-established aging energization time is reached, the notification device can reliably notify based on it. Moreover, since the notification is made by sound, the user can be made aware even though the notification device is built in the terminal block case. Furthermore, when this power supply terminal block is attached to a lighting fixture, the power supply terminal block is used regardless of whether or not the lighting fixture is equipped with an electronic ballast. The notification device can notify that a predetermined energization time has been reached at a predetermined time.

  In this notification, the notification device can output a sound for a certain time each time an electric device in which the notification device is incorporated, for example, a lighting fixture is turned on. In this case, for example, it can be notified only at the start of lighting that the luminaire has arrived at a time suitable for replacement, and at the time of normal lighting after that, no notification sound is emitted so that the user is not concerned. Can be. When such consideration is not required, it is only necessary to continuously notify indefinitely, whereby the notification effect can be continued.

  Furthermore, in the present invention, the sound output of the sound output unit in the notification device based on reaching the presumed aging energization time at a predetermined time may be repeated at regular time intervals. In this case, since the notification operation is performed at regular time intervals regardless of whether the power supply to the electrical equipment is turned on or off, for example, whether the lighting fixture is turned on or off, it is incorporated into a lighting fixture for a store open for 24 hours, for example. It is suitable as a power terminal block.

  In addition, it is preferable that the sound output operation of the notification device of the present invention for a certain period or unlimited sound output operation gradually increase the number of outputs, output time, or volume. Such sound output control can be performed by a microcomputer having a function as a measurement unit.

  Here, the sound output operation in which the number of outputs gradually increases means that the sound output in the first fixed period after reaching the presumed aging energization time at a predetermined time is, for example, in the form of “peep”. The sound output mode in a certain period of time is “Peepy”, the sound output mode in the next fixed period is “Peepy”, and the number of outputs is gradually increased in the same manner.

  Furthermore, the sound output operation in which the output time is gradually increased is, for example, when the sound output for the first certain period after reaching the pre-established aged energization time at a predetermined time, for example, continues for 2 seconds, The sound output in the form of “pee” in the next fixed period continues for 4 seconds, the sound output in the form of “pee” in the next fixed period continues for 6 seconds, and the sound output time gradually increases in the same manner. Points to be.

  Further, the sound volume gradually increases means that the amplitude of the output sound gradually increases and the sound becomes louder. This can be applied to a sound output operation in which the number of outputs gradually increases and a sound output operation in which the output time gradually increases.

  And when the notification device of the present invention is configured so that these notification operations can be obtained, after reaching the presumed aging energization time at a predetermined time, the appeal effect to the user by the notification of sound output gradually increases. Since it is enhanced, it is preferable in that the user can finally be surely notified while avoiding discomfort due to the sound of the notification being too loud from the beginning.

  The power terminal block of the invention according to claim 2 is provided with the positive electrode wire insertion hole for load and the negative electrode wire insertion hole for load on one side wall of the terminal block case, and the both speed connection terminals are provided on the one side wall. The notification device is arranged between the other side wall of the terminal block case positioned between and the two-speed connection terminal.

  According to the second aspect of the present invention, the notification device does not get in the way of inserting the load electric wire into the load positive electrode and negative electrode electric wire insertion holes and connecting them to the quick connection terminal.

  According to a third aspect of the present invention, there is provided the power supply terminal block, wherein a groove extending in the thickness direction of the terminal block case is formed on the inner surface of another pair of side walls of the terminal block case connecting the one side wall and the other side wall.

The circuit board is disposed, and the measurement unit and the sound output unit are mounted on a plate surface far from the both speed connection terminals of the circuit board.

  In this invention of Claim 3, a notification apparatus can be easily assembled in the predetermined position in a terminal block case by inserting a circuit board in the groove | channel of a terminal block case. And since the measurement part and sound output part of the notification apparatus incorporated in this way are kept away from a quick connection terminal, the insulation resistance performance of the measurement part and sound output part with respect to a quick connection terminal is securable.

  In the invention of claim 6, the output operation of the sound output unit can be stopped by the sound muffling means if necessary. Therefore, when a plurality of electrical devices such as lighting fixtures to which the power supply terminal block of the present invention is attached are wired, only the sound output portion of the power supply terminal block attached to, for example, one of the electrical devices is effective. Thus, the sound output unit of the notification device built in the other power terminal block can be prevented from functioning effectively. Therefore, the sound output unit of all the notification devices does not operate based on the fact that the presumed aging energization time has been reached, and the notification can be prevented from becoming noisy.

  In addition, the notification device 61 is disposed with the surface of the circuit board 62 on which the measurement unit 63 and the sound output unit 64 are mounted facing the third side wall 12c. In other words, the measurement unit 63 and the sound output unit 64 are mounted on one surface of the circuit board 62 positioned farther from the positive electrode fast connection terminal 41 and the negative electrode quick connection terminal 42. Thereby, since the measurement part 63 and the sound output part 64 of the notification device 61 are kept away from the positive connection terminal 41 for the positive electrode and the quick connection terminal 42 for the negative electrode, the insulation resistance of the measurement part 63 and the sound output part 64 with respect to these fast connection terminals. Performance can be secured.

  Next, the procedure for assembling the power terminal block 5 will be described.

  First, the assembled notification device 61 is assembled into the fourth housing chamber 17 of the case body 12 so as to be dropped from above. As described above, the circuit board 62 is placed on the upper side 62a where the printed contact is provided, and the measuring unit 63 and the sound output unit 64 face the third side wall 12c of the case body 12 as described above. It is possible to simply carry out the operation without inserting a special support component and using a tool with the effort of simply inserting the side edge of the circuit board 62 into the groove 30 in the posture. Thereby, the notification device 61 is incorporated in a predetermined position of the fourth storage chamber 17.

  Next, the quick connection terminal 41 for the positive electrode is assembled so as to drop into the first housing chamber 14 of the case body 12 from above, and the quick connection terminal 42 for the negative electrode 42 is dropped into the second storage chamber 15 of the case body 12 from above. Incorporate as follows. In the final stage of the incorporation, the clamping part 50a is elastically deformed with respect to the clamping part 50a of the connection part 50 included in the positive electrode quick connection terminal 41 and the negative electrode fast connection terminal 42, and the clamping part 50a is connected to the upper side part 62a of the circuit board 62. To fit. Thereby, the connecting portion 50 is elastically brought into close contact with a printed contact (not shown) of the circuit board 62, and the positive electrode quick connection terminal 41, the negative electrode quick connection terminal 42, and the notification device 61 are electrically connected. With this connection, the circuit board 62 can be supported so that the notification device 61 does not move in the thickness direction of the case body 12.

  Finally, by attaching the case back cover 13 to the case body 12 and assembling the terminal block case 11, the positive connection terminal 41 for positive electrode, the quick connection terminal 42 for negative electrode and the like are held so as not to move, and the power terminal block 5 Assembling work is completed.

  As a result of this assembly, the notification device 61 is disposed in the terminal block case 11 on the side of the positive connection terminal 41 for the positive electrode and the quick connection terminal 42 for the negative electrode. The notification device 61 does not overlap the thickness direction of the terminal block case 11 with respect to the quick connection terminal 42 and the thickness of the power supply terminal block 5 does not increase. For this reason, when promoting thinning of the lighting fixture 1 provided with the power terminal block 5, it is possible to prevent the power terminal block 5 from hindering the thinning.

  In the lighting fixture 1 provided with the power terminal block 5, the notification device 61 is built in the terminal block case 11 of the power supply terminal block 5, and the speed for positive electrode in which the notification device 61 is built in the terminal block case 11. The connection terminal 41 and the negative electrode quick connection terminal 42 are electrically connected. For this reason, the notification device 61 can be installed together with the power supply terminal block 5 separately from the power supply terminal block 5, saving the trouble of mounting the notification device 61 and supplying power to the notification device 61. This eliminates the trouble of wiring processing.

  In addition, since the connection portion 50 is provided integrally with the positive electrode quick connection terminal 41 and the negative electrode quick connection terminal 42 and is directly fitted to the circuit board 62 to carry out the electrical connection, the lead wire responsible for this connection is provided. There is no need for a dedicated part such as the above and the trouble of connecting this part to the circuit board 62 by soldering or the like.

  When the power supply terminal block 5 is in use, a core wire peeled off from a supply positive electrode wire (not shown) is inserted into the supply positive electrode insertion hole 21, and this core wire is a supply wire receiving portion 43 of the positive connection terminal 41 for positive electrode. And is locked between the supply locking piece 46a. Similarly, a peeled core wire of a supply negative electrode wire (not shown) is inserted into the supply negative electrode wire insertion hole 23, and the core wire is connected to the supply wire receiving portion 43 of the negative electrode quick connection terminal 42 and the supply lock piece. It is sandwiched between 46a and locked. Accordingly, power is supplied to the notification device 61 via the positive electrode quick connection terminal 41 and the negative electrode quick connection terminal 42.

  In addition, as shown in FIG. 4, the connection part 50 does not oppose the electric wire clamping part which the electric wire receiving part 43 for supply and the locking piece 46a for supply make. Thereby, when the supply positive electrode wire and the supply negative electrode wire are pushed in excessively deeply, the connecting portion 50 is not pushed so as to approach the case back cover 13 by the core wire. Therefore, it is preferable in that the electrical connection of the connecting portion 50 of the positive electrode quick connection terminal 41 and the negative electrode quick connection terminal 42 to the notification device 61 can be maintained in a predetermined state.

  When performing feed wiring if necessary, a core wire peeled off from a feed positive wire (not shown) is inserted into the feed positive wire insertion hole 22, and this core wire is a feed wire receiving portion of the positive connection terminal 41 for positive electrode. 44 and the locked locking piece 46b. Similarly, a stripped core wire of a feeding negative electrode wire (not shown) is inserted into the feeding negative electrode wire insertion hole 24, and the core wire is connected to the feeding wire receiving portion 44 of the negative electrode quick connection terminal 42 and the feeding locking piece. It is sandwiched between 46b and locked.

  Further, a core wire, which is not shown, is peeled off from a load positive electrode electric wire and is inserted into the load positive electric wire insertion hole 26, and the core wire is connected to the load electric wire receiving portion 47 of the positive electrode quick connection terminal 41. And the locking lock piece 49 for loading. Similarly, a stripped core wire of a negative electrode wire for negative electrode (not shown) is inserted into the load negative electrode wire insertion hole 27 of the quick connection terminal 42 for negative electrode, and this core wire is a load wire receiving portion of the quick connection terminal 42 for negative electrode. 47 and the load locking piece 49 are sandwiched and locked. Thereby, power is supplied to the electronic ballast and the fluorescent lamp 4.

  In the insertion connection of these load electric wires, the notification device 61 does not get in the way in the power supply terminal block 5 having the above-described configuration. That is, the third side wall 12c of the terminal block case 11 located on the opposite side between the positive connection terminal 41 and the negative connection terminal 42 with respect to the first side wall 12a of the terminal base case 11; The notification device 61 is disposed between the positive electrode quick connection terminal 41 and the negative electrode quick connection terminal 42. Therefore, the notification device 61 disposed on the side of the positive electrode quick connection terminal 41 and the negative electrode quick connection terminal 42 has the first side wall in which the load positive electrode electric wire insertion hole 26 and the load negative electrode electric wire insertion hole 27 are opened. 12a is interposed between the positive connection terminal 41 for the positive electrode and the quick connection terminal 42 for the negative electrode to prevent the inserted load electric wire from reaching the fast connection terminal 41 for the positive electrode and the quick connection terminal 42 for the negative electrode. Absent.

  Then, when power supply to the lighting fixture 1 is started and the measurement unit 63 of the notification device 61 built in the power supply terminal block 5 measures that the pre-established aging energization time has been reached, the sound output unit 64 is based on the measurement. To release sound. In this case, the sound is emitted through the terminal block case 11 and is emitted to the outside without being attenuated by passing through the sound emission hole 25. Although the notification device 61 is built in the terminal block case 11 as described above, it is assumed that the presumed aging energization time has been reached by emitting sound, that is, the luminaire 1 has reached the service life. The user can be informed and noticed that it is time to replace the appliance.

  By the way, although the lighting fixture 1 is provided with the electronic ballast accompanied by heat_generation | fever, since the power supply terminal block 5 is arrange | positioned outside the electronic ballast, the notification apparatus 61 in the power supply terminal block 5 is an electronic ballast. There is no fear that the operation reliability deteriorates due to the heat. Therefore, the notification device 61 can reliably notify at a predetermined time on the basis of measuring that the pre-estimated aging energization time has been reached.

  In addition, although the lighting fixture of this embodiment is equipped with the electronic ballast, since the power supply terminal block 5 is used irrespective of whether the lighting fixture 1 is equipped with electronic ballasts, such as an electronic ballast, an electronic ballast is used. By using the power supply terminal block 5 for a lighting fixture that does not include a ballast, when the lighting fixture reaches a presumed aging energization time, it can be notified by the notification device 61 at a predetermined time based thereon.

  A second embodiment of the present invention will be described with reference to FIG.

  In 2nd Embodiment, it replaces with extending the connection part 50 of the quick connection terminal 41 for positive electrodes, and the quick connection terminal 42 for negative electrodes from the electric wire receiving part 43 for supply, and it is the electric wire for load from the electric wire receiving part 43 for positive electrodes. A part extending over the receiving portion 47, for example, the connecting portion 45, is integrally provided so as to extend toward the notification device 61. Therefore, even if a force is applied to the supply wire receiving portion 43 due to the insertion of the feed positive wire or the feed negative wire between the supply wire receiving portion 43 and the supply locking piece 46a, The influence of slight deformation or the like of the supply wire receiving portion 43 due to the above does not affect the connection portion between the clamping portion 50a of the connection portion 50 and the circuit board 62. Therefore, it is preferable in that the electrical connection of the connecting portion 50 of the positive electrode quick connection terminal 41 and the negative electrode quick connection terminal 42 to the notification device 61 can be maintained in a predetermined state.

  Except for the matters described above, the second embodiment is the same as the first embodiment. Therefore, for the reason already described in the first embodiment, the desired problem of the present invention can be solved also in the second embodiment.

Since the third embodiment is the same as the first embodiment except for the items described below, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In the third embodiment, a load electric wire receiving portion 47 is provided on the feeding electric wire receiving portion 44 through the other connecting portion 51 substantially in parallel therewith. A lock piece base 48 supported by the front wall 12 e of the case body 12 is bent from the load wire receiving portion 47, and a load lock piece 49 is cut and raised on the lock piece base 48. The front wall 12e is provided with a load positive electrode insertion hole 26 that penetrates the front wall 12e and faces the load locking piece 49, and similarly has a load negative electrode insertion hole 27 (not shown in FIG. 6). Opened.

  Since all the wire insertion holes are provided in the front wall 12e without providing the load positive electrode insertion hole 26 and the load negative electrode insertion hole 27 in the first side wall 12a of the case main body 12 in this way, the case main body 12 The length extending between the first side wall 12a and the third side wall 12c is shortened, and the power supply terminal block 5 can be formed in a small size.

  Further, the fourth storage chamber 17 is formed on the first side wall 12a side. Therefore, the partition wall 20 is provided in the case body 12 so as to face and oppose the load wire receiving portion 47. A notification device 61 is built in the fourth storage chamber 17. Correspondingly, the connecting portion 50 of the positive electrode quick connection terminal 41 and the negative electrode quick connection terminal 42 (not shown in FIG. 6) extends from the load wire receiving portion 47 to the notification device 61 and is integrally provided. .

  Except for the matters described above, the second embodiment is the same as the first embodiment. Therefore, for the reason already described in the first embodiment, the intended problem of the present invention can be solved also in the third embodiment.

  A fourth embodiment of the present invention will be described with reference to FIG. Since the fourth embodiment is the same as the first embodiment except for the items described below, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In the fourth embodiment, for example, a switch 71 is attached to the power supply terminal block 5 described in the first embodiment as a sound muting means for arbitrarily stopping the notification operation of the sound output unit 64. For example, the switch 71 is mounted on the circuit board 62 of the notification device 61 so as to face the sound emission hole 25 of the terminal block case 11. The switch 71 is turned on / off each time it is pressed by a shaft-shaped tool passed through the sound emission hole 25, and the on state or the off state is maintained until it is next pressed. Yes. Other configurations of the power terminal block 5 are the same as those of the power terminal block of the first embodiment.

  A plurality of lighting fixtures (not shown in FIG. 7, but only the ceiling wall 2 of the fixture body is shown) provided with the power terminal block 5 are arranged in a straight line on the indoor ceiling of the building. The power supply terminal blocks 5 adjacent to each other in the direction in which the lighting fixtures are arranged are electrically connected in series by a feed wiring. In FIG. 7, reference numeral 72 indicates a wire for feed wiring, and reference numerals 73 and 74 indicate power supply wires.

  Except for the matters described above, the second embodiment is the same as the first embodiment. Therefore, for the reason already described in the first embodiment, the intended problem of the present invention can be solved also in the fourth embodiment.

  Moreover, in the fourth embodiment, the power supply terminal block 5 includes the switch 71, which is preferable in the following points.

  That is, after feeding and wiring a plurality of lighting fixtures installed on the ceiling in the building, for example, one of the power supply terminal blocks 5 of these lighting fixtures, for example, the power supply terminal block of the lighting fixture located at the end of the power feeding direction While the switch 71 of 5 is turned on and the switch 71 of the other lighting fixtures is turned off, the lighting fixtures arranged in a row are used. As a result, only when the sound output unit 64 included in the notification device 61 of the power terminal block 5 having the switch 71 in the ON state is effectively notified after reaching the presumed aging energization time, The sound output unit 64 of the notification device 61 incorporated in the power supply terminal block 5 other than that does not perform the notification operation. Thereby, since the sound output part 64 of all the notification apparatuses 61 does not notify based on having reached the presumed aging energization time, it can prevent that notification becomes noisy.

  In the fourth embodiment, a manually operated switch is provided as a sound muting means, but it can be replaced with the following. That is, the sensor detects that the wire 72 for feed wiring sandwiched between the supply wire receiving portion 43 and the supply locking piece 46a is connected to the quick connection terminal, and the micro signal to which this detection signal is supplied. A computer may be used to turn off the sound muting means composed of a semiconductor switch. Accordingly, only the notification device 61 of the power supply terminal block 5 in which the supply positive electrode wire and the supply negative electrode wire are sandwiched between the supply wire receiving portion 43 and the supply locking piece 46a is effective. At the same time, the sound output unit 64 in the power supply terminal block 5 to which the wire 72 for feed wiring is connected is automatically set so as not to perform the notification operation, so that it is special for preventing the notification operation. It does not require time and effort.
