Description

  The present invention relates to a control device for a lighting device having an internal power source that can be used when power supply from an external power source is cut off, and a lighting system using the same.

  Conventionally, lighting devices have been used at sites such as tunnel construction and night construction. In such a field, an electric wire having a main electric wire and a plurality of branch electric wires branching from the main electric wire is connected to a power supply device (external power source), and the electric wire is arranged at a place where illumination is required. A lighting system in which a lighting device is attached to each branch wire is used (for example, see Patent Document 1).

  However, if the power is cut off due to a power failure due to a failure of the power supply device or power supply switching at the time of tunnel construction, the lighting device is not turned on, causing inconveniences such as danger.

  In order to solve such a problem, there is a lighting device that includes a battery (internal power source) and is configured to be lit by the power from the battery when the power from the power source is cut off (for example, a patent) Reference 2). In such a lighting device, even if the power supply from the power supply device is cut off by, for example, operating the external switch to “off”, the lighting continues with the battery. Therefore, such an illumination device cannot be turned off only by operating an external switch. In particular, when such an illumination device is used in an illumination system as described in Patent Document 1, in order to turn off all the illumination devices, it is necessary to individually switch off each illumination device. And it becomes very complicated.

FIG. 1 is a schematic view of an illumination system according to the present invention. In this embodiment, the lighting system is used at the construction site of the tunnel T.
[Lighting system]

By inserting the plug 3p into a socket 23 provided at the tip of the branch electric wire 22, power from the AC power source P is supplied to the lighting device 3. be able to.

  FIG. 2 is a schematic view of the illumination device 3 in the present embodiment. As shown in the figure, the lighting device 3 includes a substantially cylindrical case 31 and a substrate 34 on which a plurality of LEDs 35 (an example of the light source of the present invention) are mounted. Various materials can be used as the material of the case 31, and for example, polycarbonate can be used. Various materials can be used as the material of the substrate 34, but it is preferable to use aluminum because heat dissipation is improved.

  A first end of the case 31 is provided with an end cap 32, and a cover tube 33 is provided at the second end. The end face on the second end side of the lighting device 3 is provided with the above-described electric wire 3c and a switch 36 for turning on and off the lighting device 3. An illumination control device 4 for controlling the illumination device 3 is provided inside the illumination device 3 covered with the cover tube 33.

  The illumination control device 4 includes a control unit 41, an AC-DC converter 42, a battery 43 (an example of the internal power source of the present invention), a power source switching unit 44, an LED drive circuit 45, and a memory 46. The control unit 41 performs various controls, and for example, a one-chip microcomputer can be used. The AC-DC converter 42 converts the alternating current supplied from the alternating current power supply P through the electric wire 3c into a direct current, and supplies the direct current to the LED 35, the battery 43, and the like. The battery 43 is charged by the power supplied from the AC-DC converter 42, and supplies power to the LED 35 and the like when the power supply from the AC power source P is cut off. The power source switching unit 44 can switch the power supply source to the LED 35 or the like to either the AC-DC converter 42 or the battery 43. In addition, power supply can be cut off.

The memory 46 stores a voltage value of alternating current (direct current from the AC-DC converter 42) from the alternating current power supply P for a predetermined time (in this embodiment, at least 4.5 seconds). Although various devices can be used as the memory 46, it is preferable to use a non-volatile storage medium because the memory can be retained even if power from the AC power source P is not supplied for a long time due to a power failure or the like. Although no connection is shown in the figure, the control unit 41 is supplied with power from the battery 43. Thereby, the control part 41 can operate | move also when supply of the electric power from AC power supply P is cut | disconnected.
[Lighting device state transition]
FIG. 3 is a state transition diagram showing a state transition of the lighting device 3 in the present embodiment. With reference to this figure, how the state of the lighting device 3 changes depending on the operation of the switch 36 and the presence / absence of power supply from the AC power supply P will be described. In the initial state (S0) here, the lighting device 3 is turned off, the lighting mode when the lighting is last turned on is stored in the memory 46, and the power supply from the AC power P is cut off. Shall.

  In the following description, a state in which power from the AC power source P is supplied is referred to as “AC power ON”, and a state in which power supply from the AC power source P is disconnected is referred to as “AC power OFF”. Further, a state where the power supply source to the power source switching unit 44 is the battery 43 is expressed as “battery ON”, and a state where the power source P is the AC power source P (AC-DC converter 42) is expressed as “battery OFF”. .

  When “AC power is ON” in the extinguished state (S0), the control unit 41 reads the lighting mode from the memory 46, and the power supply source is the AC-DC converter 42 with respect to the power source switching unit 44. Control is performed so that the battery is turned off (S1). If the read lighting mode is the “half lighting mode”, the control unit 41 instructs the LED driving circuit 45 to drive the LED 35 at 500 Lm, and causes the LED 35 to light half (S2). On the other hand, if the read lighting mode is “all lighting mode”, the control unit 41 instructs the LED driving circuit 45 to drive the LED 35 at 1000 Lm, and turns on the LED 35 all (S3).

  This state is a normal lighting state in which lighting is performed by power from the AC power supply P. In this normal lighting state, each time the switch 36 is operated, the control unit 41 drives the LED so that “half-lighting (S2)” → “full lighting (S3)” → “lighting-off (S4)” is cyclically switched. The circuit 45 is controlled. When the mode is switched by operating the switch 36, the control unit 41 stores the mode after switching in the memory 46.

  When the illuminating device 3 is turned on (S2 or S3) and “AC power is OFF”, the control unit 41 determines that the voltage fluctuation pattern of the power from the AC power supply P is a predetermined “light-off signal” voltage fluctuation pattern. (S5). In this embodiment, the voltage fluctuation pattern of the “light-off signal” is “AC power OFF” for 1.5 seconds (low voltage section of the first time of the present invention) → “AC power ON” for 1.5 seconds (this (High voltage section of the second time of the invention) → “AC power OFF” of 1.5 seconds (low voltage section of the third time of the present invention). Therefore, the control unit 41 stores the voltage value of the alternating current (direct current from the AC-DC converter 42) from the alternating current power supply P every predetermined time, for example, every 0.1 second, in the memory 46, and stores the voltage value. The change of the voltage value is compared with the change of the voltage of the “light-out signal” described above. The memory 46 stores voltage values for at least the past 4.5 seconds.

  Here, when the control unit 41 determines that the AC voltage fluctuation pattern from the AC power supply P does not match the voltage fluctuation pattern of the “light-off signal”, the control unit 41 transitions to an emergency lighting state driven by the battery 43. Let Specifically, the control unit 41 controls the power source switching unit 44 so that the power supply source is the battery 43, that is, “battery ON”, and the LED drive circuit 45 is “half-lit”. Control is performed to drive the LED 35 in “mode” (S6).

  In this emergency lighting state, the control unit 41 controls the LED driving circuit 45 so that “half lighting (S6)” → “extinguishing (S7)” is cyclically switched every time the switch 36 is operated. That is, in the emergency lighting state, all the lights are turned off in the “half lighting mode”. Thereby, the lighting time in the battery 43 is made longer.

  When the LED 35 is “half-lit” in the emergency lighting state and becomes “AC power ON”, the control unit 41 reads the lighting mode from the memory 46 and “battery OFF” to the power source switching unit 44. (S1).

On the other hand, in S5, when the control unit 41 determines that the AC voltage fluctuation pattern from the AC power supply P matches the voltage fluctuation pattern of the “light-off signal”, the control unit 41 causes the LED drive circuit 45 to On the other hand, control is performed to turn off the LED 35 (S0). Thereby, the illumination device 3 is completely turned off.
〔Control device〕
FIG. 4 is a connection diagram inside the control device 1 in the present embodiment. As shown in the figure, the control device 1 of this embodiment includes a DC power source 11 (an example of the power source of the present invention), a switch 12 (an example of the operation input unit of the present invention), a first timer relay 13, and a second timer relay. 14, a third timer relay 15 and a power relay 16 (an example of the relay of the present invention). 4A shows the connection of power lines, and FIG. 4B shows the connection of control signal lines. In the present embodiment, the DC power source 11, the switch 12, the first timer relay 13, the second timer relay 14, the third timer relay 15 and the power relay 16 constitute a turn-off signal generation unit of the present invention.

  The direct current power supply 11 converts alternating current supplied from the alternating current power supply P into direct current. The converted direct current is supplied directly or indirectly to the first timer relay 13, the second timer relay 14, the third timer relay 15, and the power relay 16.

  The first timer relay 13 includes a control circuit 13a, a first control terminal 13b, a second control terminal 13c, a first terminal 13d, a second terminal 13e, and a switch 13f. The first terminal 13 d is connected to V + of the DC power supply 11, and the second terminal 13 e is connected to the second control terminal 16 h of the power relay 16. A switch 13f is provided between the first terminal 13d and the second terminal 13e.

  The first terminal 13d and the second terminal 13e are so-called b terminals, and in a state in which power is not supplied to the first control terminal 13b and the second control terminal 13c (initial state), the switch 13f The terminal 13d and the second terminal 13e are in a conductive state. The control circuit 13a controls the switch 13f with the electric power supplied to the first control terminal 13b and the second control terminal 13c so that the first terminal 13d and the second terminal 13e are electrically connected or disconnected. Specifically, the control circuit 13a, after power is supplied to the first control terminal 13b and the second control terminal 13c, after the delay time t1 (first delay time) has elapsed, the first terminal 13d and the second terminal 13e. The switch 13f is controlled so as to be in a disconnected state. In the present embodiment, the first delay time t1 = 1.5 seconds corresponding to the “light-off signal” described above. On the other hand, when the supply of power to the first control terminal 13b and the second control terminal 13c is cut off, the switch 13f immediately returns to the initial position, and the first terminal 13d and the second terminal 13e are in a conductive state. It becomes.

  The second timer relay 14 has the same configuration as that of the first timer relay 13, and the control circuit 14a controls the switch 14f with electric power supplied to the first control terminal 14b and the second control terminal 14c. However, the first terminal 14d and the second terminal 14e are so-called a terminals, and in a state in which power is not supplied to the first control terminal 14b and the second control terminal 14c (initial state), the switch 14f is The position between the first terminal 14d and the second terminal 14e is in a disconnected state. The delay time t2 (second delay time) of the second timer relay is 3 seconds, which is longer than the first delay time t1.

  The first terminal 14 d is connected to V + of the DC power supply 11, and the second terminal 14 e is connected to the second terminal 15 e of the third timer relay 15. That is, the output of the second timer relay 14 is input to the third timer relay 15.

  The third timer relay 15 has the same configuration as the first timer relay, and the control circuit 15a controls the opening and closing of the switch 15f with the electric power supplied to the first control terminal 15b and the second control terminal 15c. However, the delay time t3 (third delay time) of the third timer relay is 4.5 seconds, which is longer than the second delay time t2. The second terminal 15e is connected to the second terminal 14e of the second timer relay 14 as described above, and the first terminal 15d is connected to the second control terminal 16h of the power relay 16.

  The power relay 16 includes a first terminal 16a, a second terminal 16b, a third terminal 16c, a fourth terminal 16d, a first switch 16e, a second switch 16f, a first control terminal 16g, a second control terminal 16h, and a control unit 16i. I have. The first terminal 16a and the third terminal 16c are connected to the AC power source P. A first switch 16e is provided between the first terminal 16a and the second terminal 16b. A second switch 16f is provided between the third terminal 16c and the fourth terminal 16d.

  As described above, the second terminal 13e of the first timer relay 13 and the first terminal 15d of the third timer relay 15 are connected to the second control terminal 16h. On the other hand, the first control terminal 16 h is connected to V− of the DC power supply 11. The controller 16i controls the first switch 16e and the second switch 16f to be in a “closed” state when power is supplied to the first control terminal 16g and the second control terminal 16h. That is, all terminals of the power relay 6 are so-called a terminals.

  The switch 12 can be manually operated to “open” and “close”, and can thereby supply or disconnect power to the first timer relay 13, the second timer relay 14, and the third timer relay 15. . When the lighting device 3 is in a normal lighting state, the switch 12 is in an “open” state.

Hereinafter, the flow of power from the DC power supply 11 when the switch 12 is in the “open” state will be described. In this state, power is not supplied to the control circuits 13a, 14a and 15a of the first timer relay 13, the second timer relay 14 and the third timer relay 15, respectively. Therefore, each switch 13f, 14, and 15f is in an initial state. Therefore, the first terminal 13d and the second terminal 13e of the first timer relay 13 are in a conductive state. Similarly, the first terminal 15d and the second terminal 15e of the third timer relay 15 are in a conductive state. On the other hand, the first terminal 14d and the second terminal 14e of the second timer relay 14 are disconnected. Therefore, V + of the DC power supply 11 is in a conductive state with the second control terminal 16h of the power relay 16 via the first timer relay 13, and the first control terminal 16g and the second control terminal 16h of the power relay 16 are connected to each other. Power is supplied. Therefore, the first switch 16e and the second switch 16f of the power relay 16 are in the “closed” state. As a result, the first terminal 16a and the second terminal 16b, the third terminal 16c and the fourth terminal 16d of the power relay 16 become conductive, and the power from the AC power supply P is supplied to the electric wire 2 via the power relay 16. Is done. Therefore, the illuminating device 3 will be in a lighting state.
[Behavior of lighting system]
FIG. 5 is a time chart when the switch 12 is operated. The behavior of the control device 1 and the lighting device 3 will be described with reference to the flowchart of FIG. In FIG. 5, regarding the AC power supply P, the state in which the power is supplied from the AC power supply P is “ON”, and the power is supplied from the AC power supply P by a power failure or the “OFF” operation of the AC power supply P switch. The state that is not displayed is described as “OFF”. Regarding the switch 12, a state in which the DC power supply 11 and the first timer relay 13 and the like are conducted by operating the switch 12 is represented as “closed”, and a state in which the DC power source 11 is not conducting is represented as “open”. For the first timer relay and the like, the state where the first terminal 13d and the second terminal 13e and the like are conductive is expressed as "closed", and the state where the first terminal 13d and the like are not conductive is expressed as "open". Similarly, for the power relay 16, the first terminal 16a and the second terminal 16b are in a conductive state, that is, the state in which the first switch 16e and the like are “closed” is expressed as “closed”. Further, a state where the lighting device 3 is turned on is referred to as “light”, and a state where the lighting device 3 is turned off is referred to as “off”.

  In the initial state of the time chart of FIG. 5, the AC power source P is energized, and the switch 12 is in the “open” state. In this state, power is not supplied to the control terminals 13b, 13c, 14b, 14c, 15b, and 15c of the first timer relay 13, the second timer relay 14, and the third timer relay 15. Accordingly, the first timer relay 13 and the third timer relay 15 are in the “closed” state, and the second timer relay 14 is in the “open” state. Therefore, the electric power from the DC power supply 11 is supplied to the first control terminal 16g and the second control terminal 16h of the power relay 16, and the power relay 16 is also in the “closed” state. Therefore, the electric power from the AC power supply P is supplied to the lighting device 3 via the power relay 16 and the electric wire 2, and the lighting device 3 is in the “light” state. This is the state of S2 or S3 in the flowchart of FIG.

  In such a state, the switch 12 is artificially operated to the “closed” state at time T1 (an example of the artificial operation of the present invention). Then, the electric power from the DC power supply 11 is supplied to the first control terminal 13b, the second control terminal 13c, and the like of the first timer relay 13. However, as described above, the first timer relay 13, the second timer relay 14, and the third timer relay 15 have the delay times t1 (= 1.5 seconds), t2 (= 3 seconds), and t3 (= 4. 5 seconds) is set, and the state of the switch 13f or the like does not change unless the delay time has elapsed. Therefore, the state of each relay and the lighting device 3 does not change until 1.5 seconds have elapsed from time T1 (until time T2).

  When 1.5 seconds elapse from time T1 (time T2), the state of the switch 13f of the first timer relay 13 changes, and the first timer relay 13 enters the “open” state. On the other hand, the second timer relay 14 remains in the “open” state. Therefore, the supply of power from the DC power supply 11 to the power relay 16 is cut off, and the power relay 16 is in the “open” state. Accordingly, power supply from the AC power source P to the lighting device 3 is cut off. This behavior is a transition from S2 or S3 to S5 in the flowchart of FIG. Then, in S5, the control part 41 of the illuminating device 3 determines whether the voltage fluctuation pattern from this time (time T2) to 4.5 second before corresponds with the voltage fluctuation pattern of a "light extinction signal." As described above, the voltage variation pattern of the “light-off signal” in the present embodiment is “AC power OFF” for 1.5 seconds → “AC power ON” for 1.5 seconds → “AC power OFF” for 1.5 seconds. In this case, it is determined that the signal is not a “light-off signal”. Therefore, the process proceeds from S5 to S6, and the control unit 41 of the lighting device 3 performs control so that the “battery ON” and “half-lighting mode” are set. Thereby, the illuminating device 3 will be in an emergency lighting state, and will be lighted by the battery 43 drive (hatching part of FIG. 5).

  When 1.5 seconds elapses from time T2, that is, when 3 seconds elapses from time T1 (time T3), the state of the switch 14f of the second timer relay 14 changes and the second timer relay 14 is "closed". It becomes a state. At this time, the third timer relay is in the “closed” state. Accordingly, the supply of power from the DC power supply 11 to the power relay 16 is resumed, the power relay 16 is in a “closed” state, and the supply of power from the AC power supply P to the lighting device 3 is also resumed. This behavior is a transition from S6 to S1 in the flowchart of FIG. Then, in S <b> 1, the control unit 41 of the lighting device 3 performs control so that “battery OFF” and the lighting mode read from the memory 46 are set (transition from S <b> 1 to S <b> 2 or S <b> 3). Thereby, the illuminating device 3 is turned on by the electric power from the AC power source P.

  When 1.5 seconds elapses from time T3, that is, when 4.5 seconds elapse from time T1 (time T4), the state of the switch 15f of the third timer relay 15 changes, and the third timer relay 15 Opened state. At this time, the first timer relay 13 is also in the “open” state. Therefore, the supply of power from the DC power supply 11 to the power relay 16 is cut off again, the power relay 16 is in the “open” state, and the supply of power from the AC power supply P to the lighting device 3 is also cut off. This behavior is a transition from S2 or S3 to S5 in the flowchart of FIG. Then, in S <b> 5, the control unit 41 of the lighting device 3 determines whether or not this voltage fluctuation pattern matches the voltage fluctuation pattern of the “light-out signal”. Here, the voltage fluctuation pattern 4.5 seconds before time T4 matches the voltage fluctuation pattern of the “light-off signal”. Therefore, the control part 41 of the illuminating device 3 performs control so as to be “battery OFF” and “light extinction” (transition from S5 to S0). Thereby, the illuminating device 3 turns off.

  As described above, in the present illumination system, it is possible to generate the “light-off signal” simply by “closing” the switch 12. Therefore, as shown in FIG. 1, even when a plurality of lighting devices 3 are provided, all the lighting devices 3 can be turned off after a predetermined delay time has elapsed simply by “closing” the switch 12. it can.

In this way, when the switch 12 is operated to the “open” state at the time T5 with the lighting device 3 turned off, the respective switches 13f of the first timer relay 13, the second timer relay 14, and the third timer relay 15 are operated. , 14f and 15f are simultaneously “closed”, “open” and “closed”, respectively. Therefore, the DC power supply 11 and the power relay 16 become conductive through the first timer relay 13, and the power relay 16 enters the “closed” state. Therefore, power from the AC power supply P is supplied to the lighting device 3 via the power relay 16 (transition from S0 to S1), and the lighting device 3 is lit in a normal lighting state (transition from S1 to S2 or S3). ).

As described above, when the switch 12 is operated in the off state, the states of all the relays are changed almost simultaneously, and the lighting device 3 can be turned on with almost no time lag.

  On the other hand, FIG. 6 shows the time when the power supply is restarted after the power supply from the AC power supply P is cut off due to a power failure or the like in the state where the lighting device 3 is lit by the power from the AC power supply P. It is a chart.

  The power supply from the AC power supply P to the control device 1 is cut off at time T11 due to a power failure or the like. At this time, the switch 12 is in the “open” state. Therefore, the first timer relay 13 and the third timer relay 15 are in the “closed” state, and the second timer relay 14 is in the “open” state. Therefore, although the DC power supply 11 and the power relay 16 are in a conductive state, power is not supplied to the DC power supply 11, so power is supplied to the first control terminal 16 g and the second control terminal 16 h of the power relay 16. Instead, the power relay 16 is in the “open” state. Further, the power supply from the AC power source P to the power relay 16 is also cut off. Accordingly, the power supply from the AC power source P to the lighting device 3 is also cut off. Then, in the flowchart of FIG. 3, the process transits from S2 or S3 to S5. And the control part 41 of the illuminating device 3 determines whether the voltage fluctuation pattern before 4.5 seconds before T11 corresponds with the voltage fluctuation pattern of a "light extinction signal". Here, since they do not match, the control unit 41 performs control so that the “battery ON” and “half-lighting mode” are set (transition from S5 to S6). That is, the illumination device 3 is in an emergency lighting state (hatched portion in FIG. 6).

  The power failure is restored at time T12, and the supply of power from the AC power source P to the control device 1 is resumed. At this time, since the switch 12 is in the “open” state, the states of the first timer relay 13, the second timer relay 14, and the third timer relay 15 are not changed. On the other hand, since the power supply from the DC power supply 11 and the AC power supply P is resumed to the power relay 16, the power relay 16 is in a “closed” state, and the power from the AC power supply P is also supplied to the lighting device 3. Supply is resumed. Then, the process proceeds from S6 to S1, and the control unit 41 performs control so that the battery mode is “ON” and the lighting mode immediately before time T11 is set (transition from S1 to S2 or S3).

Thus, in this lighting system, when the supply of power from the AC power supply P is cut off during lighting, the lighting system shifts to the emergency lighting mode without turning off, and the battery 43 continues lighting in the “half lighting mode”. . Thereafter, when the supply of power from the AC power supply P is resumed, the lighting in the lighting mode immediately before the emergency lighting state is resumed by the power from the AC power supply P.
[Another embodiment]
(1) In this embodiment, the voltage from the AC power supply P is used when determining the “light-off signal”, but a dedicated signal may be used.
(2) In the present embodiment, the control device 1 is provided with the DC power supply 11. However, if the relays that operate with AC power are used, the DC power supply 11 is not necessary. In this case, the AC power source P may be used as the power source.
