Embodiment 1 FIG.
FIG. 1 is an exploded perspective view of the lighting apparatus according to Embodiment 1. FIG. The lighting device 100 is installed on, for example, a wall surface of a stair landing or a wall surface of a ramp. The lighting device 100 is a stairway guide light that also serves as an emergency lighting fixture. That is, the lighting device 100 is an emergency lighting fixture and stairway guide light. Therefore, the illuminating device 100 is a lighting device for disaster prevention installed in a stair landing or the like. The lighting device 100 functions as a normal lighting device during normal use, and guides the refugee so that the refugee can evacuate safely and quickly during a power failure or the like. In order to satisfy the requirements of an emergency lighting fixture, the lighting device 100 that is an emergency lighting fixture combined use stairway guide light secures an illuminance of at least 1 lux when the light emitting member is a light bulb, and the light emitting member is a fluorescent lamp or LED. In the case of, it is designed to ensure an illuminance of 2 lux. This enables evacuation activities during power outages.

  The illumination device 100 includes a main body 100a, a reflector 120 attached to the main body 100a, and a light emitting member 130. The light emitting member 130 is a lamp, for example. The main body 100a includes a sensor 101, an emergency light unit 102, a sensor unit 103, a regular lighting unit 104, a storage battery 105, a power terminal block 106, an inspection switch 107, a sensor on / off switch 108, a charge monitor 109, and a signal device terminal for a guide light. A stand 111 and a wall switch use non-use setting switch 201 are arranged. The sensor 101 is not particularly limited as long as it detects a situation outside the lighting device 100, and is, for example, a human sensor or an illuminance sensor.

  FIG. 2 is a detailed view of the power terminal block 106. The power terminal block 106 is provided with a first terminal 200A, a second terminal 200B, and a third terminal 200C. A white wiring 200a is connected to the first terminal 200A, and a black wiring 200b is connected to the second terminal 200B. When a wall switch is used, the red wiring 200c is connected to the third terminal 200C. FIG. 2 shows a short-circuit line 150 used for short-circuiting the second terminal 200B and the third terminal 200C. The short-circuit line 150 is attached by a construction worker. In lighting device 100 according to Embodiment 1 of the present invention, short-circuit wire 150 is not used.

  FIG. 3 is a diagram illustrating the connection between the wiring and the AC power supply. The white wiring 200a connected to the first terminal 200A is connected to one end of the AC power supply. The black wiring 200b connected to the second terminal 200B is connected to the other end of the AC power supply. The AC power source is, for example, a commercial power source. A wall switch 210 is provided in the middle of the red wiring 200c connected to the third terminal 200C. When the wall switch 210 is turned on, the red wiring 200c and the black wiring 200b are connected and both wirings have the same potential. At this time, AC power is supplied to the red wiring 200c and the white wiring 200a. When the wall switch 210 is off, the red wiring 200c has no potential, so that AC power is not supplied between the red wiring 200c and the white wiring 200a. As described above, the third terminal 200C and the red wiring 200c are connected to the AC power supply via the wall switch 210.

  FIG. 4 is a block diagram illustrating a configuration of the illumination device 100. The emergency light unit 102 is connected to the first terminal 200A and the second terminal 200B, and receives supply of AC power from these terminals. The emergency light unit 102 charges the storage battery 105. The emergency light unit 102 causes the storage battery 105 to cause the light emitting member 130 to emit light in an emergency where the AC power supply 200 is stopped and a power failure occurs. In other words, the emergency light unit 102 causes the storage battery 105 to cause the light emitting member 130 to emit light when AC power cannot be obtained from the first terminal 200A and the second terminal 200B.

  The regular lighting unit 104 is connected to the first terminal 200 </ b> A and is connected to the second terminal 200 </ b> B via the sensor unit 103. That is, the service lighting unit 104 is electrically connected to the first terminal 200A and the second terminal 200B. The normal lighting unit 104 causes the light emitting member 130 to emit light via the emergency light unit 102 with the power of the AC power source 200 in the normal state where the AC power source 200 is operating. At this time, the emergency light unit 102 connects the regular lighting unit 104 and the light emitting member 130 while charging the storage battery 105. Although the regular lighting unit 104 has a light-off function, it may have a light control function instead of the light-off function, or may have both a light-off function and a light control function.

  Two sensors 101 are connected to the sensor unit 103. The sensor unit 103 acquires information of the two sensors 101. The sensor unit 103 has a wall switch signal detection unit 103a. The wall switch signal detection unit 103a is connected to the third terminal 200C. The sensor unit 103 is connected to the first terminal 200A and the second terminal 200B. Thus, the sensor unit 103 receives all the signals from the outside and controls the regular lighting unit 104 based on them. In order to process various input signals, the sensor unit 103 preferably includes a microcomputer or the like.

  The regular lighting unit 104, the emergency light unit 102, and the sensor unit 103 are so-called voltage-free products corresponding to AC 100V to 254V. The sensor unit 103 includes a step-down circuit 103 b that steps down the voltage of the AC power supply 200 and supplies the voltage to the sensor 101. A voltage of several tens to several VDC is generated from the AC power supply 200 by the step-down circuit 103b. As a result, the power supply voltage and size of the sensor 101 can be freely selected. Further, it is possible to prevent the sensor 101 from being turned off except during a power failure.

  A sensor on / off switch 108 is connected to the sensor unit 103. When the sensor ON / OFF switch 108 is in the “sensor ON” position (“ON” at this time), the sensor unit 103 turns on the light emitting member 130 when detecting a person based on the signal of the sensor 101, When there is no light, the power supply to the light emitting member 130 is stopped and the light is turned off. At this time, it can be selected whether the light is turned off or dimmed by dimming according to the setting of the regular lighting unit 104.

  In the sensor unit 103, the illuminance of the light emitting member 130 when the sensor on / off switch 108 is on and a person 101 is detected as a human sensor, and the illuminance of the light emitting member 130 is on. 101 is set to be higher than the illuminance of the light emitting member 130 when no person is detected. For example, when the sensor 101 is an illuminance sensor, the sensor unit 103 increases the illuminance of the light emitting member 130 when the illuminance detected by the sensor 101 is smaller than a predetermined value, and the illuminance detected by the sensor 101 is predetermined. When it is equal to or greater than the obtained value, the illuminance of the light emitting member 130 can be reduced. Thus, during normal use, the sensor unit 103 issues a command to the regular lighting unit 104 according to the external situation detected by the sensor 101.

  On the other hand, when the sensor on / off switch 108 is set to the “sensor off” position (“off” at this time), the information of the sensor 101 is not transmitted to the sensor unit 103. Thus, the sensor on / off switch 108 can switch whether or not the information of the sensor 101 is reflected in the control of the regular lighting unit 104. When the illumination device 100 does not include the sensor 101, the sensor on / off switch 108 is set to “off”.

  At the time of a power failure, the sensor 101, the sensor unit 103, and the regular lighting unit 104 do not operate, and the light emitting member 130 is lit in an emergency using the power of the storage battery 105 charged by the emergency light unit 102 during regular use. It should be noted that safety can be ensured by always lighting the light emitting member 130 by the emergency light unit 102 regardless of whether or not a person is detected at the time of a power failure. The lighting device 100 has all functions required for the lighting device as an emergency lighting fixture and stairway guide light.

  A wall switch use non-use setting switch 201 is connected to the sensor unit 103. The wall switch use / non-use setting switch 201 switches the wall switch 210 used to turn off the light emitting member 130 between the use state and the non-use state. When the red wiring 200c is not wired, it is not possible to identify whether the sensor unit 103 should turn off the light or the red wiring 200c is not originally present. Therefore, it is necessary to set whether the wall switch 210 is present from the outside. The setting is performed by the wall switch use non-use setting switch 201. The user uses the wall switch non-use setting switch 201 to set the presence or absence of the wall switch 210. As a setting at the time of shipment, the wall switch 210 is not turned off.

  A case without the wall switch 210 will be described. The absence of the wall switch 210 means that the wall switch 210 is not turned off. In this case, the contractor only connects the white wiring 200a to the first terminal 200A and connects the black wiring 200b to the second terminal 200B, and does not provide the red wiring 200c. The absence of the red wiring 200c means that no wiring is connected to the third terminal 200C from the outside. Then, by setting the wall switch use non-use setting switch 201 to “off”, the wall switch 210 is not used. Then, the sensor unit 103 recognizes that the wall switch 210 is not used in the lighting device 100, and the light emitting member 130 is not turned off by the wall switch 210. In other words, when the wall switch use / non-use setting switch 201 is switched to the non-use state, the sensor unit 103 switches the regular lighting unit 104 to lighting or extinguishing based on the on / off operation of the wall switch 210.

  A case where the wall switch 210 is provided will be described. The presence of the wall switch 210 means that the wall switch 210 is turned off. In this case, the contractor connects the white wiring 200a to the first terminal 200A, the black wiring 200b to the second terminal 200B, and the red wiring 200c to the third terminal 200C. As a result, the third terminal 200C is connected to the same polarity as the second terminal 200B. A wall switch 210 is provided on the path of the red wiring 200c between the other end of the AC power supply 200 and the third terminal 200C. Even when the wall switch 210 is off, the light emitting member 130 is lit in the initial state. The user sets the wall switch 210 to be used by operating the wall switch non-use setting switch 201 and turning it on. As a result, the light emitting member 130 can be turned on or off by the wall switch 210. In other words, when the wall switch use non-use setting switch 201 is switched to the use state, the sensor unit 103 turns on or off the regular lighting unit 104 based on the on / off operation of the wall switch 210 connected to the third terminal 200C. Switch off.

  Here, a comparative example will be described in order to facilitate understanding of the significance of the lighting apparatus 100 according to Embodiment 1 of the present invention. FIG. 5 is a block diagram of a lighting device according to a comparative example. The lighting device of FIG. 5 is set so as not to be turned off using a wall switch. For this reason, the wiring of the wall switch 210 is indicated by a dotted line. A short-circuit line 150 that short-circuits the second terminal 200B and the third terminal 200C is attached to the power terminal block 106. The short-circuit line 150 is attached by a construction contractor. By attaching the short-circuit line 150, the same voltage as the second terminal 200B is applied to the service lighting unit 104.

  For example, the two sensors 101 are respectively installed at both ends of the lighting device 100 in the longitudinal direction. The power of the sensor 101 is taken from the first terminal 200A and the second terminal 200B of the power terminal block 106. AC power is directly supplied to the sensor 101 and the sensor unit 103 from the first terminal 200A and the second terminal 200B. The transformer in the power supply path is used only when the AC power supply is other than AC100V. When the lighting device 100 is supplied with power from the AC power source 200, power is supplied to each unit in the device via the first terminal 200A and the second terminal 200B. Between the first terminal 200A and the emergency light unit 102, there is an always-on inspection switch 107. Only when the inspection operation is performed, the inspection switch 107 is turned off. In this description, the number of sensors 101 of the lighting device 100 is two. However, the number of sensors is not limited to two, and may be one or any number, and the arrangement of the sensors 101 may be changed depending on the shape of the lighting device 100.

  When the fire signal from the guide light signal device 121 is received by the guide light signal device terminal block 111, the sensor unit 103 places all the light emitting members 130 on the regular lighting unit 104 even if the sensor 101 does not detect a person. Turn on with light. The guide lamp signal device 121 is supplied with AC 100 V during normal use, but is not energized when a fire occurs.

  When the wall switch 210 can be turned off without providing the short-circuit line 150, turning off the wall switch 210 cuts off the input on one side of the regular lighting unit 104. When the second terminal 200 </ b> B and the third terminal 200 </ b> C are short-circuited by the short-circuit line 150, AC power is supplied to the normal lighting unit 104 during normal use. In the configuration of the comparative example, it is necessary for the construction contractor to switch the presence / absence of the short-circuit wire 150 in accordance with the user's request, and thus it is easy to make an operation error.

  On the other hand, in the first embodiment of the present invention, the presence or absence of the wall switch 210 can be set without using the short-circuit line 150. Therefore, it is possible to prevent a mistake that the construction contractor should provide the short-circuit line 150 but the short-circuit line 150 is not provided, or the short-circuit line 150 is unnecessary but the short-circuit line 150 is provided. Also, by integrating the sensor 101 information, the sensor on / off switch 108 on / off information, and the wall switch use / non-use setting switch 201 information into the sensor unit 103, the sensor unit 103 can be designated by the sensor unit 103 with a simple configuration. Can be realized.

  The illumination device 100 according to Embodiment 1 of the present invention can be variously modified within a range that does not lose its characteristics. FIG. 6 is a block diagram of a lighting device according to a modification. This illuminating device is provided with a signal lamp terminal block 111. The guide light signal device terminal block 111 connects the guide light signal device 121 and the sensor unit 103 to each other. When the fire alarm detects a fire, a fire signal is output to the sensor unit 103 via the guide light signal device 121 and the guide light signal device terminal block 111. The sensor unit 103 that has received the fire signal issues a command for lighting the light emitting member 130 with all light to the regular lighting unit 104 regardless of the operation state of the wall switch 210. Thereby, the light emitting member 130 emits light. Therefore, even if the wall switch use non-use setting switch 201 is turned on and the wall switch 210 is turned off and the wall switch 210 is requested to turn off, the light emitting member 130 is caused to emit light if a fire signal is issued. be able to.

  FIG. 7 is a block diagram of a lighting device according to another modification. In the lighting device of FIG. 6, the other end of the AC power source 200 and the regular lighting unit 104 are connected via the second terminal 200 </ b> B and the inside of the sensor unit 103. The utility lighting unit 104 is controlled by turning on / off the current to the regular lighting unit 104 by the sensor unit 103. In contrast, in the lighting device of FIG. 7, the second terminal 200 </ b> B is directly connected to the regular lighting unit 104. Then, the operation of the regular lighting unit 104 is set by the sensor unit 103 in which various types of information are collected. This eliminates the need to supply power to the regular lighting unit 104 from the second terminal 200B via the sensor unit 103, thereby simplifying the configuration of the sensor unit 103.

  The sensor unit 103 of the illumination device 100 according to Embodiment 1 of the present invention receives all external signals and controls the regular lighting unit 104 based on them. Therefore, the sensor unit 103 may receive signals other than those described above. For example, the sensor unit 103 may receive a turn-off signal notifying that the vicinity of the lighting device 100 is unmanned or that the building is locked. Upon receiving the turn-off signal, the sensor unit 103 turns off the lighting device. The guide light signal device 121 is configured to send the above-described extinguishing signal to the sensor unit 103 in addition to sending a fire signal to the lighting device 100.

  These modifications can be applied as appropriate to lighting devices according to the following embodiments. In addition, since the illuminating device which concerns on the following embodiment has many common points with Embodiment 1, it demonstrates centering on difference with Embodiment 1. FIG.

Embodiment 2. FIG.
FIG. 8 is a block diagram of a lighting apparatus according to Embodiment 2. An inspection switch 107 a is connected to the sensor unit 103. The inspection switch 107a is handled when the lighting device 100 is inspected. The inspection of the lighting device 100 is to confirm the operation of the emergency light unit 102 and the life of the storage battery 105 by simulating a power failure state. As an inspection method, there are an inspection in which the AC power source 200 itself is shut off to bring the light emitting member 130 into a power failure state, and an inspection in which the light emitting member 130 is made to light by using a check switch 107a to create a simulated power failure state.

  The sensor unit 103 stops the operation of the regular lighting unit 104 and operates the emergency light unit 102 when the inspection switch 107a is operated. For this purpose, the sensor unit 103 sends a signal indicating that the inspection is being performed to both the emergency light unit 102 and the service lighting unit 104. Thereby, the emergency lighting operation by the storage battery 105 using the emergency light unit 102 can be performed while the regular lighting unit 104 is turned off.

  Further, in addition to the above-described inspection, it is preferable to enable an automatic inspection using an individual control method. The automatic check of the individual control method is a function of continuing the emergency lighting state by performing the start-up operation of the automatic check and determining whether or not the storage battery 105 can effectively light the light emitting member 130 for a specified time or more. . For the microcomputer built in the sensor unit 103, it is preferable to distinguish between an inspection signal to be inspected from the inspection switch 107a and an inspection signal to be automatically inspected by the individual control method. For example, if the inspection is performed while the inspection switch 107a is being operated and the inspection switch 107a is pressed for a long time or the remote control operation is performed from the outside, the automatic inspection of the individual control method is started. become able to.

  In the case of emergency lighting fixtures and stairway guide lights, there is often no sensor control. Further, the emergency light unit 102 is often provided with an operation unit that receives an inspection switch inspection signal. In the operation section, it is preferable to receive an inspection signal to be inspected and an inspection signal to perform an automatic inspection of the individual control method, and to distinguish them. Then, the operation unit can be used in common, and the automatic inspection function can be realized without providing the general emergency light unit 102 with the automatic inspection function of the individual control method. Of course, if another switch is provided for the individual control type automatic inspection, the inspection operation and the self-inspection operation can be completely separated.

  By the way, as shown in FIG. 4, the lighting device of Embodiment 1 is provided with an inspection switch 107 in the in-device wiring connected to the first terminal 200A. That is, the inspection switch 107 is connected to the white wiring 200a. In this case, the AC power source 200 is directly cut off by the inspection switch 107. Therefore, the inspection switch 107 having a large withstand voltage and a large contact capacity is required.

  On the other hand, since the inspection switch 107a is attached to the sensor unit 103 in Embodiment 2 of the present invention, it is not necessary to directly cut off the AC power supply 200 with the inspection switch 107a. Therefore, a signal switch having a low withstand voltage and a small contact capacity can be used as the inspection switch 107a. Thereby, the inspection switch 107a can be made small, or an inexpensive switch can be provided as the inspection switch 107a.

Embodiment 3 FIG.
FIG. 9 is a block diagram of a lighting apparatus according to Embodiment 3. As the light emitting members, a first light emitting member 140 connected to the regular lighting unit 104 and a second light emitting member 131 connected to the emergency light unit 102 are provided. The sensor unit 103 lights the first light emitting member 140 during normal use, and lights the second light emitting member 131 during an emergency such as a power failure. Thus, even if the light emitting member for normal use and the light emitting member for emergency are separately provided, the first light emitting member 140 can be turned off and the second light emitting member 131 can be operated for emergency lighting during inspection work. The automatic inspection of the individual control system is not complicated.

  FIG. 10 is a block diagram of a lighting device according to a comparative example. The inspection switch 107 a is attached to the emergency light unit 102. Therefore, even if the inspection switch 107a is operated at the time of inspection, an inspection signal is not sent to the regular lighting unit 104. If it does so, since the 1st light emitting member 140 will continue to light even if it is in check operation, operation will be confused. In this comparative example, the AC power supply 200 itself can be shut off by providing an inspection switch on the internal wiring connected to the first terminal 200A. FIG. 11 is a block diagram of a lighting device according to another comparative example. The inspection switch 107 is connected to the first terminal 200A. In this case, an increase in the size of the inspection switch 107 is inevitable.

  In contrast, in the third embodiment of the present invention, the inspection switch 107a is provided in the sensor unit 103, and at the time of inspection, a signal is output from the sensor unit 103 to both the regular lighting unit 104 and the emergency light unit 102. Thereby, an inspection can be easily performed without using a large inspection switch. Note that the features of the lighting devices according to the embodiments described so far may be combined as appropriate.
