In the present invention, the product life is detected based on the power supply voltage and current passing through the wire connector and the environment around the wire connector.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of a lighting apparatus according to the first embodiment of the present invention.

  In FIG. 1, reference numeral 1 denotes a fluorescent lamp illuminating device that is embedded and installed on the ceiling side, for example, and this device 1 includes a chassis 11 having an open bottom surface. A pair of lamp sockets 12 are respectively attached to both ends of the chassis 11 in the longitudinal direction, and a straight fluorescent lamp 13 is attached over the lamp sockets 12 facing the longitudinal direction of the chassis.

  Inside the chassis 11, a power terminal block 20 is mounted between the two fluorescent lamps 13, and a lighting device (not shown) made of, for example, an electronic ballast is mounted. The power terminal block 20 is connected to a power line (not shown) that is drawn into the chassis 11 from the back of the ceiling through a power line drawing hole provided in the chassis. Further, the power terminal block 20 is connected to the lighting device via a load line (in-appliance wiring) (not shown) and is connected to the lamp socket 12 on one end side in the longitudinal direction of the chassis 11 via a load line (not shown). . The lighting device is connected to the lamp socket 12 on the other end side in the longitudinal direction of the chassis 11 through another load line (not shown).

  Next, with reference to FIG. 2 thru | or 4, the power supply terminal block as an electric wire connector which concerns on this embodiment is demonstrated in detail. 2 is a perspective view showing the external appearance of the power terminal block 20 according to this embodiment, FIG. 3 is a schematic diagram showing the circuit configuration of the power supply system of the power terminal block 20 according to this embodiment, and FIG. It is a block diagram which shows the function structure of the power supply terminal block 20 which concerns on a form.

  As shown in FIG. 2, the power supply terminal block 20 of this embodiment has a substantially rectangular parallelepiped housing having a stepped portion on one side surface. On the upper surface of the power supply terminal base 20, a pair of power supply line terminals 21 for connecting a power supply line for supplying power from the outside, and a feed power supply line for supplying power to another instrument (not shown) different from the instrument 1 Are provided with a pair of power supply line terminals 22. In addition, a region protruding from the upper surface of the power terminal block 20 is provided with a pair of ground wire terminals 24 for connecting a ground wire. Further, two pairs of loads for connecting a load line for supplying power to a load (such as a lighting device) in the appliance 1 are adjacent to the side surface having the stepped portion of the power terminal block 20 and on the side surface on the side of the feed power line terminal 22. A line terminal 23 is provided.

  In a region sandwiched between the pair of power supply line terminals 21, the feed power supply line terminal 22, and the ground line terminal 24, a release switch for releasing the wire connected to these from the fixed state is disposed. The power line terminal 21, the feed power line terminal 22, the load line terminal 23, and the ground line terminal 24 are configured so that the wire is fixed and electrically connected by directly inserting the wire stripped from the end of the clothes into these. Has been. The inserted wire is released by pressing the release switch 25 and can be extracted.

  As shown in FIG. 3, in the power terminal block 20 of this embodiment, the power line terminal 21 is electrically connected to the load line terminal 23 by a conducting wire 26 made of, for example, a strip-shaped copper plate. The feed power line terminal 22 is electrically connected on the conducting wire 26 between the power line terminal 21 and the load line terminal 23. The power line terminal 21 is connected to a power source 30 such as a commercial power source via a switch (not shown) or the like. The load line terminal 23 is electrically connected to a load in the appliance 1 such as an inverter or a lamp via the load line. That is, when power is applied from the power supply 30 to the power supply line terminal 21 via the power supply line, power is supplied to the load line terminal 23 via the feed power supply line terminal 22. The power supplied to the load line terminal 23 is supplied to the load 32 via the load line.

  A constant voltage power supply unit 34 is electrically connected to the load line terminal 23. When power is supplied to the load line terminal 23, power is also supplied to the constant voltage power supply unit 34. The constant voltage power supply unit 34 is a power source that supplies power to the monitoring unit 36 that detects the life of the appliance 1 and notifies the user. The monitoring unit 36 has a function of detecting the life of the lighting fixture 1 from the environmental state around the power terminal block 20 and informing the user. The constant voltage power supply unit 34 may generate the starting power supply for the monitoring unit 36 by using, for example, a primary battery instead of the power supplied from the power supply 30 via the conductor 26.

  Since the power supply line terminal 21 and the feed power supply line terminal 22 are connected to a power supply line and a feed power supply line to which power from the power supply 30 is directly supplied, for example, φ1.6 to φ2. It is configured such that a zero VVF cable or the like can be fixed and electrically connected with one touch. On the other hand, since the load line terminal 23 supplies power to the load of the lighting equipment to be incorporated, for example, a φ0.8 to φ1.0 IV wire with the end covering stripped off can be fixed and electrically connected with one touch. It can be connected.

  As described above, when power is supplied to the power line terminal 21, the power terminal block 20 according to this embodiment is supplied with power in the order of the feed power line terminal 22 and the load line terminal 23, and is supplied to the load line terminal 23. The supplied power is also supplied to the constant voltage power supply unit 34. Therefore, even when a problem occurs in the power input of the constant voltage power supply unit 34 or the load 32, it is possible to supply stable power to the feed power supply line terminal 22 upstream thereof.

  As shown in FIG. 4, the monitoring unit 36 includes a clock unit 41, a counter 42, a memory unit 43, a comparison unit 44, and a notification unit 45. The monitoring unit 36 has a function of receiving the power from the constant voltage power supply unit 34 and monitoring the life of the lighting fixture 1.

  The clock unit 41 is a clock oscillator that oscillates a reference signal. The counter 42 is a timer that counts elapsed time based on the clock signal oscillated by the clock unit 41. The memory unit 43 is a rewritable and non-volatile memory, and a count value indicating the life of the instrument 1 is stored in advance as life information. That is, the memory unit 43 has a function of holding stored data even when power supply from the constant voltage power supply unit 34 is stopped. The memory unit 43 may store a value that allows for a margin in the count value indicating the life of the appliance 1, that is, a count value that goes back about several months of the product life. In this case, the life can be notified to the user at the stage before the product life comes. In the case where the constant voltage power supply unit 34 generates the starting power supply for the monitoring unit 36 not by the power supply 30 but by a primary battery or the like, the memory unit 43 may be a volatile memory instead of a non-volatile memory.

  The comparison unit 44 is a comparator that compares the count value of the counter 42 with the count value stored in the memory unit 43. The comparison unit 44 has a function of sending a trigger signal to the notification unit 36 when the count value of the counter 42 exceeds the count value stored in the memory unit 43. The notification unit 45 is a user interface provided with means for notifying the user of the lifetime, such as a buzzer or a lamp. When the notification unit 45 receives the trigger signal from the comparison unit 44, the notification unit 45 notifies the user that the lighting fixture 1 has reached the end of life (or that the lifetime is near), for example, by sounding a buzzer provided in the notification unit 45. Note that the notification unit 45 may be configured to generate and output a notification signal when receiving a trigger signal from the comparison unit 44. In this case, by arranging a light emitting diode or the like in a place that can be seen from the outside of the chassis 11 of the instrument 1 and connecting it so as to be issued by the notification signal, the user can be notified visually of the end of the life of the instrument 1. it can. For the notification by the notification unit 45, various types of information such as visual notification by a lamp means in addition to auditory notification such as a buzzer can be used.

  Note that the monitoring unit 36 includes a reset terminal RST that erases all or part of the stored contents of the memory unit 43. For example, the product life of the instrument 1 may be extended when the instrument 1 is largely repaired by replacing the initial failure. In such a case, it is possible to manage the product life more accurately by initializing only the count value of the counter 42 among the contents stored in the memory unit 43 by turning the reset terminal RST on and off with the ground or the power supply. Become.

  Here, with reference to FIG. 3 and FIG. 4, operation | movement of the instrument 1 provided with the power supply terminal block 20 of this embodiment is demonstrated.

  When the power supply line is connected to the power supply line terminal 21 and a power supply 30 is connected to the power supply line terminal 21 by turning on a switch (not shown), power is supplied to the feed power supply line terminal 22 through the conductor 26. When power is supplied to the feed power line terminal 22, power is supplied to a tool 1 a (feed tool) different from the tool 1. The appliance 1a is a lighting fixture arranged adjacent to the appliance 1, for example.

  Next, power is supplied to the load line terminal 23 through the conductor 26. The load line terminal 23 is connected to the load 32 via the load line, and the load 32 is activated when power is supplied to the load line terminal 23. The load 32 is a lamp device including, for example, an inverter 32a, a lamp 32b, and the like, and includes not only the lamp 32b that emits light but also an inverter 32a and further all elements that can consume power in the appliance 1, such as a load line. Shall be.

  Then, the power is supplied to the constant voltage power supply unit 34 through the conductive wire 26, and a predetermined voltage is applied to the monitoring unit 36. When a voltage is applied to the monitoring unit 36, the clock unit 41 starts generating a reference signal. The clock unit 41 gives the generated reference signal to the counter 42 and other logic circuits. When the reference signal is generated, the counter 42 starts counting at a predetermined clock, accumulates the count value, and records / updates the accumulated value in the memory unit 43 as accumulated information. The counter 42 records / updates the count value in the memory unit 43 when the power supply 30 is turned off (when the user turns off the lamp 32b), the last count value is stored, and the total lighting time of the lighting fixture 1 To get. If the constant voltage power supply unit 34 generates the power supply of the monitoring unit 36 not by the power supply 30 but by a primary battery or the like, the monitoring unit 36 can maintain operation regardless of whether or not the power supply 30 is supplied. In such a case, it is not always necessary to record / update the count value in the memory unit 32.

  The comparison unit 44 compares the count value of the counter 42 with the count value corresponding to the lifetime of the lighting fixture 1 stored in advance in the memory unit 43 (or the time obtained by taking a margin for the lifetime). As a result of the comparison, when the count value at the time of comparison exceeds the count value corresponding to the life or the like stored in advance in the memory unit 43, the comparison unit 44 generates a trigger signal and sends it to the notification unit 45. Upon receiving the trigger signal, the notification unit 45 notifies the user of the end of the lifetime by, for example, sounding a buzzer provided in the notification unit 45.

  Here, the notification unit 45 may notify immediately after receiving the trigger signal, or may notify at a predetermined timing after receiving the trigger signal. For example, after receiving the trigger signal, the notification may be made at the timing when the power supply from the power supply 30 is switched from off to on. In this case, since the user is notified when the lighting fixture is next turned on, the user can easily recognize. Moreover, you may alert | report at the timing which the power supply from the power supply 30 switched off after acceptance of a trigger signal. In this case, the user is notified when the lighting fixture is turned off. In particular, when the notification is made by the lamp means, the user can easily recognize by turning on the lamp means after the lighting fixture is turned off.

  Thus, the power supply terminal block 20 of this embodiment supplies power to the load 32 via the power supply line terminal 22 to which the power supply line is connected, the power supply line terminal 22 to which the power supply line is connected, and the load line. Since the load line terminal 23 and the constant voltage power supply unit 34 are connected in this order by the conducting wire 26, power can be supplied with priority to the power supply that supplies power to the adjacent lighting fixtures. In addition, the power terminal block 20 of this embodiment includes a counter that generates a count value corresponding to the total time that the lighting fixture has been operated, and a comparison unit 44 that compares a predetermined count value stored in the memory unit 43. Since the notification unit 45 is configured to perform a notification operation based on the comparison result, it is possible to notify the user that the total usage time of the lighting fixture has reached a predetermined lifetime.

  Next, a power supply terminal block according to another embodiment will be described with reference to FIG. FIG. 5 is a block diagram showing a functional configuration of the power supply terminal block according to the second embodiment. A power supply terminal block 120 shown in FIG. 5 further includes a detection unit 46 in the configuration of the power supply terminal block 20 according to the first embodiment shown in FIG. Therefore, the same components as those of the power supply terminal block of the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  The detection unit 46 is a sensor provided on the conductive wire 26 between the constant voltage power supply unit 34 and the load line terminal 23. The detection unit 46 has a function of monitoring voltage and current supplied to the load 32 and monitoring input characteristics of the entire load 32. The detection unit 46 passes the obtained input characteristics of the load 32 to the comparison unit 44 of the monitoring unit 36.

  Then, with reference to FIG. 5, operation | movement of the lighting fixture 1 provided with the power terminal block 120 of this embodiment is demonstrated. The operation of the power supply system from when the power supply 30 is connected to the power supply line terminal 21 until the constant voltage power supply unit 34 applies a voltage to the monitoring unit 36 is the same as that of the power supply terminal block 20 according to the first embodiment. Description to be omitted is omitted.

  In this embodiment, power is supplied to the load line terminal 23 via the detection unit 46. The detection unit 46 monitors the input voltage and input current supplied to the load 32 through the load line and sends the data to the comparison unit 44 of the monitoring unit 36. Here, it is assumed that the memory unit 43 stores the aging data of the input characteristics of the load 32 in advance as characteristic change information.

  The comparison unit 44 compares the data sent from the detection unit 46 with the secular change data stored in the memory unit 43. As a result of the comparison, when the data sent from the detection unit 46 indicates the life of the load 32 or a state close to the life, the comparison unit 44 sends a trigger signal to the notification unit 45. Upon receiving the trigger signal, the notification unit 45 sounds a buzzer provided to notify the user of the end of the lifetime. Therefore, even if the count value of the counter 42 has not reached the count value corresponding to the product life stored in the memory unit 43, notification according to the state of the load 32 is possible.

  In the power supply terminal block 120 shown in FIG. 5, the comparison of the count value by the counter 42 and the comparison of the input characteristics by the detection unit 46 are performed together, but the present invention is not limited to this. The clock unit 41 and the counter 42 may be omitted, and the life of the load 32 and, hence, the arrival of the product life of the luminaire 1 may be notified based only on the input characteristics sent from the detection unit 46. .

  As described above, the power supply terminal block 120 of this embodiment directly monitors the input voltage and input current supplied to the load 32 and serves as a basis for determining the product life. It is possible to respond to the arrival of product life due to.

  Next, a power supply terminal block according to another embodiment will be described with reference to FIG. FIG. 6 is a block diagram illustrating a functional configuration of a power supply terminal block according to the third embodiment. The power supply terminal block 220 shown in FIG. 6 further includes a sensor unit 47 in the configuration of the power supply terminal block 20 according to the first embodiment shown in FIG. Therefore, the same components as those of the power supply terminal block of the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  The sensor unit 47 is an environmental sensor provided in the casing of the power terminal block 220, and is, for example, a temperature sensor. The sensor unit 47 has a function of detecting the temperature environment around the power terminal block 220 and sending temperature data to the monitoring unit 36. Note that the sensor unit 47 may be configured to indirectly detect the temperature of the load 32 (for example, the inverter 32a) via the conductor 26. Here, it is assumed that temperature change data due to aging of the load 32 is stored in the memory unit 43 as temperature change information in advance.

  Then, with reference to FIG. 6, operation | movement of the instrument 1 provided with the power terminal block 220 of this embodiment is demonstrated. Since the power supply 30 is common to the power supply terminal block 20 according to the first embodiment from the time when the power supply 30 is connected to the power supply line terminal 21 until the power supply 30 is supplied to the load 32 through the load line, the redundant description is omitted.

  The sensor unit 47 detects the temperature around the power terminal block 220 and sends the temperature data to the comparison unit 44 of the monitoring unit 36. The comparison unit 44 compares the temperature data sent from the sensor unit 47 with the temperature change data stored in the memory unit 43. As a result of the comparison, when the temperature data sent from the sensor unit 47 indicates the life or abnormality of the load 32, the comparison unit 44 sends a trigger signal to the notification unit 45. Upon receiving the trigger signal, the notification unit 45 sounds a buzzer provided to notify the user of the end of the lifetime.

  In the power supply terminal block 220 shown in FIG. 6, the comparison of the count value by the counter 42 and the comparison of the input characteristics by the detection unit 46 are performed together, but the present invention is not limited to this. The clock unit 41 and the counter 42 may be omitted, and only the temperature data sent from the sensor unit 47 may be used to notify the life of the load 32, that is, the arrival of the product life of the lighting fixture 1. .

  As described above, the power supply terminal block 220 of this embodiment indirectly monitors the surrounding temperature environment and serves as a basis for determining the product life, so that the product life due to failure or the like is not limited to mere aging. Can also respond.

The power supply terminal block 320 shown in FIG. 7 further includes a switch unit 48 in the configuration of the power supply terminal block 20 according to the first embodiment shown in FIG. Therefore, the same components as those of the power supply terminal block of the first embodiment are denoted by the same reference numerals, and redundant description is omitted. The switch part 48 opens and closes the conducting wire 26 to which the load line terminal 23 is connected. That is, the switch unit 48 operates to turn on / off the power supply to the load 32 based on an instruction from the monitoring unit 36.

  Then, with reference to FIG. 7, operation | movement of the instrument 1 provided with the power terminal block 320 of this embodiment is demonstrated. The operation of the power supply system from when the power supply 30 is connected to the power supply line terminal 21 until the constant voltage power supply unit 34 applies a voltage to the monitoring unit 36 is the same as that of the power supply terminal block 20 according to the first embodiment. Description to be omitted is omitted.
