Description

  The present invention relates to a monitor device and a remote control device.

  There are lighting fixtures that are obliged to be installed for disaster prevention in places such as buildings, offices, stores, and accommodation facilities. The lighting fixtures are emergency lighting fixtures (hereinafter referred to as emergency lights) that are installed in places such as living rooms, evacuation routes, stores, shared areas of hotels, and hotel rooms, and that provide effective illuminance on the floor even during power outages. And a guide light with a function indicating an evacuation route or emergency exit. Emergency lights are luminaires whose installation is stipulated by the Building Standard Law, and guide lights are evacuation facilities that are stipulated by the Fire Service Law. They seem to be similar, with different roles and jurisdictions. These lighting fixtures normally charge a battery using a commercial power source, and light the light source with the battery during a power failure. It is stipulated in the technical standards of JIS and the Japan Lighting Industry Association that a green indicator lamp (hereinafter referred to as a charge monitor) to indicate that the battery is being charged is normally provided.

  On the other hand, in order to check the state of the battery, the lighting fixture is provided with a check switch, and by operating the check switch, a power failure is simulated using a battery.

  In recent years, a built-in control device such as a microcomputer automatically performs an emergency operation for a specified time, an indicator lamp (hereinafter referred to as a lamp monitor) that displays the life or abnormality of the light source, and an inspection. Lighting fixtures having an indicator lamp (hereinafter referred to as an inspection monitor) for indicating that the inside is in the market have appeared. Also, lighting fixtures that can perform switch operations for inspection operations with a remote control device (hereinafter referred to as a remote controller) have been commercialized. In particular, with guide lights, the use of light sources instead of LEDs has led to mainstream guide lights that have a charge monitor and a lamp monitor and can be inspected by a remote controller (for example, Patent Documents 1 and 2).

The brightness setting of the light source is set to be brighter than the brightness setting immediately before reception of the brightness increase signal. With this setting, it is possible to avoid a situation where the monitor light source is difficult to see when the brightness of the monitor light source is set to be dark.
Further, the monitor light source for which the brightness is set by the control circuit is assumed to be a charge monitor 11a described later in the following embodiment.

Note that the lighting and blinking states in the case of the emergency light in FIG. 8 are merely examples, and are not limited to the pattern shown in FIG.

*** Explanation of operation ***
Next, the circuit operation of the emergency light 1 will be described. The following operation subject is the control circuit 27.
The control circuit 27 is a microcomputer, for example. When the commercial power supply 21 is supplied, the first DC-DC converter 23 converts the voltage rectified by the rectifier circuit 22 into a voltage sufficient to charge the battery 3. The voltage converted by the first DC-DC converter 23 is further converted to a voltage appropriate for the control power supply by the control power generation circuit 26 and input as a power supply for the control circuit 27. At this time, the cutoff circuit 47 is turned on (connected) by a signal from the cutoff circuit control unit 46. The converted voltage is input to the charging circuit 25 and charges the battery 3. Note that the default of the cutoff circuit 47 is on. Since the voltage is detected by the power failure detection circuit 48 that detects the output of the first DC-DC converter 23, the control circuit 27 determines that there is no power failure. At this time, since the battery 3 is charged, the charge monitor 11a is lit.
Hereinafter, this state is referred to as a charged state.

When the supply of the commercial power supply 21 is stopped (such as a power failure), the output of the first DC-DC converter 23 is lost, so the voltage of the power failure detection circuit 48 becomes zero, and the control circuit 27 determines that there is a power failure. Since there is no output of the first DC-DC converter 23, the battery 3 is not charged, so the charge monitor 11a is turned off. The battery 3 supplies power as a power source for the control circuit 27 and also supplies power to the second DC-DC converter 29. The second DC-DC converter 29 boosts the voltage of the battery 3 to a voltage higher than the voltage of the battery 3, supplies power to the lamp 6, and lights the lamp 6 with a preset current. Turning on the lamp 6 with the battery 3 is called emergency lighting.
A lamp current detection circuit 34 that feeds back the current flowing through the lamp 6 to the second DC-DC converter 29 is controlled so that the output of the lamp 6 becomes a target value. The lamp 6 may be turned on by controlling the amount of power supplied.

  When the commercial power supply 21 is restored, the first DC-DC converter 23 is operated again. Therefore, the power failure detection circuit 48 determines that the power failure has been restored and automatically returns to the charging state of the battery 3 by the charging circuit 25. . Moreover, since the second DC-DC converter control circuit 30 stops the second DC-DC converter 29, the lamp 6 is turned off.

  Next, the inspection operation will be described. The inspection operation is to confirm that the lamp 6 can be reliably turned on with the battery 3 and is legally determined (generally rated for 30 minutes, long-time rated for 60 minutes), and the battery 3 with the lamp 6 This is an operation to confirm whether or not emergency lighting can be performed.

<Inspection operation when the inspection switch 9 is pressed>
When the inspection signal is received by the inspection signal receiving unit 37 from the inspection switch 9, the control circuit 27 turns off the interruption circuit 47 from the interruption circuit control unit 46 as a pseudo power failure mode for inspecting the battery 3, and the battery 3 is charged. Disappear. When the control circuit 27 controls the second DC-DC converter control circuit 30 to operate the second DC-DC converter 29, the voltage obtained by boosting the voltage of the battery 3 by the second DC-DC converter 29 is applied to the lamp 6. The lamp current detection circuit 34 controls the lamp current to an appropriate current. At this time, the charging monitor 11a is turned off to stop charging. The inspection signal from the inspection switch 9 is output while the switch is pressed, and the control circuit 27 performs an inspection operation while the inspection signal is output. It is determined whether the control circuit 27 has been in an emergency lighting operation for a predetermined time due to deterioration of the battery by performing a check operation for a legally determined time (general rating: 30 minutes, long-time rating: 60 minutes). I can confirm.

  When the battery 3 can be lit for a predetermined time, the battery voltage detection unit 42 determines that the battery 3 is normal and maintains the charged state. When the voltage of the battery 3 decreases before reaching the predetermined time, the lamp 6 cannot continue to be lit, and the battery voltage detection unit 42 determines that the battery 3 is in an abnormal state due to deterioration or the like. When the signal from the inspection switch 9 is cut off, the control circuit 27 turns on the shut-off circuit 47 from the shut-off circuit control unit 46 and charges the battery 3, but the charge monitor 11a performs a blinking operation (FIG. 8) indicating an abnormal state. To do. Thereby, the control circuit 27 notifies the inspector that the battery 3 has deteriorated.

<Self-inspection operation when the self-inspection switch 10 is pressed>
Next, the case where the self-inspection signal is received by the self-inspection signal receiver 38 from the self-inspection switch 10 will be described. When the self-inspection signal is received from the self-inspection switch 10, the control circuit 27 confirms whether or not continuous charging is performed for 48 hours or more. If continuous charging for 48 hours or more has not been performed, the control circuit 27 continues charging without shifting to self-inspection. If the control circuit 27 has been continuously charged for 48 hours or more, the control circuit 27 proceeds to self-inspection. The control circuit 27 shifts to a pseudo power failure mode for inspecting the battery 3 for a legally determined time, returns to the original charged state after a predetermined time, performs charging, and turns on the charge monitor 11a. . At this time, if the battery voltage becomes lower than the set voltage before the predetermined time is reached, the control circuit 27 determines that the battery 3 has reached the end of its life. The fact that the battery 3 is at the end of its life is notified by blinking 11a. At this time, the battery 3 is continuously charged. The self-inspection signal from the self-inspection switch 10 becomes a self-inspection signal by pressing and holding the self-inspection switch 10 for a long time, and pressing the self-inspection switch 10 again during the self-inspection transition standby state. There is no limitation on the operation method for shifting to self-inspection while preventing erroneous operation and mischief.

Next, the remote controller 13 will be described with reference to FIG. The remote controller 13 has a structure in which buttons 15 are arranged on the main body 14. The buttons 15 include a confirmation button 15a, a self-inspection button 15b, an interruption button 15c, a manual inspection button 15d, and a monitor brightness adjustment button 15e.
(1) When the confirmation button 15a is pressed, the remote controller 13 generates and transmits a signal for confirming whether self-inspection can be performed.
(2) When the self-inspection button 15b is pressed, the remote controller 13 generates and transmits a signal for starting self-inspection.
(3) When the interrupt button 15c is pressed, the remote controller 13 generates and transmits a signal to interrupt when interrupting during self-inspection.
(4) When the manual check button 15d is pressed, the remote controller 13 generates and transmits a signal for temporarily turning on the emergency lighting, similarly to the check switch 9.
(5) When the monitor brightness adjustment button 15e is pressed, the remote controller 13 generates and transmits a brightness reduction signal or a brightness increase signal. The switching of the brightness of the monitors 11 by pressing the monitor brightness adjustment button 15e is as shown in FIG.

  The characters written on these buttons represent the outline of the operation, and this wording may not be left as it is. For example, “monitor brightness adjustment” of the monitor brightness adjustment button 15e is “monitor dark”. Such a notation may be used. Further, the arrangement of the buttons may be other than the arrangement shown in FIG.

  When the user presses the self-inspection button 15b among the buttons 15 of the remote control 13, a self-inspection signal is transmitted from the transmission unit 16 of the remote control 13. When the receiving circuit 35 receives the self-inspection signal output from the remote controller 13, the control circuit 27 shuts off the output of the first DC-DC converter 23 and charges it via the shut-off circuit control unit 46 if it is charged for 48 hours or more. Thus, the shut-off circuit 47 is turned off to make a pseudo power failure.

  Thereafter, the emergency light 1 operates in the same manner as the self-inspection when the self-inspection switch 10 is pressed, and notifies the result of the inspection of the battery 3 on the charge monitor 11a.

  When it is desired to interrupt the self-inspection, there are means such as operation of the interruption button 15c, pressing of the inspection switch 9, re-pressing of the self-inspection switch 10, turning off and on of the power source.

The manual check button 15d temporarily puts the emergency light 1 into an emergency lighting state, like the check switch 9 for the emergency light 1.
The manual check button 15d is a button for transmitting a signal for temporarily setting the emergency light 1 in an emergency lighting state.
While the manual check button 15d is being pressed, the emergency light 1 is in an emergency lighting state. Alternatively, once the manual inspection button 15d is operated, the emergency lighting state is unconditionally 3 seconds to 5 seconds, and the state automatically returns to the charging state.

  When the control circuit 27 determines that the battery 3 is normally charged, the control circuit 27 turns on the charge monitor 11 a via the charge monitor control unit 43. When the control circuit 27 determines that the battery 3 is not normally charged, the control circuit 27 turns off the charge monitor 11a via the charge monitor control unit 43 to notify that the charge state is not normal. If the control circuit 27 determines that the battery 3 has reached the end of its life after self-inspection, the control circuit 27 blinks the charge monitor 11a.

When the light is turned off at night or the like, but the surroundings are dark and the monitor 11a of the emergency light 1 is considered to be too bright, the operator points the remote control 13 at the emergency light 1 and monitors the monitor. The brightness adjustment button 15e is pressed. When the monitor brightness adjustment button 15e is pressed, as shown in FIG. 5, when the brightness setting of the charging monitor 11a is “bright” or “reference brightness”, the generation unit 15-1 generates a brightness reduction signal. Is generated. Normally, the brightness setting of the charge monitor 11a is a “reference brightness” setting. In this case, the signal receiving unit 36 of the monitor device 100 receives the brightness reduction signal via the receiving circuit 35.
When the signal receiving unit 36 receives the brightness reduction signal, the control circuit 27 controls the charge monitor of the charge monitor 11a, which is a monitor light source, more than the brightness setting immediately before receiving the brightness reduction signal. It is set dark with respect to the unit 43. Therefore, the charge monitor 11a is lit darker than immediately before receiving the brightness reduction signal. Therefore, the charge monitor 11a can sleep without disturbing sleep.

  FIG. 9 is a flowchart showing an operation when the brightness setting of the charge monitor 11a is darkened. The flowchart of FIG. 9 will be described below. 9 is a control circuit 27. In FIG. 9, the charge monitor 11 a of the monitors 11 is a target for darkening the brightness. In FIG. 9, the change in the brightness of the charging monitor 11a is caused by setting the “reference brightness” and the “dark” brightness each time the monitor brightness adjustment button 15e is pressed, as shown on the right side of FIG. The setting is switched alternately.

In step S1, the control circuit 27 uses the power failure detection circuit 48 to determine whether there is a power failure. In the case of a power failure, the process proceeds to step S13, and the control circuit 27 performs emergency lighting. If it is not a power failure, the process proceeds to step S2.
In step S <b> 2, the control circuit 27 uses the battery voltage detection unit 42 to determine whether the battery 3 is present and charging is in progress. If not, the process proceeds to step S14, and the control circuit 27 turns off the charge monitor 11a using the charge monitor control unit 43. If the battery is being charged, the process proceeds to step S3, and the control circuit 27 uses the battery voltage detector 42 to determine whether or not the battery 3 is at the end of its life. When the battery 3 is at the end of its life, the control circuit 27 causes the charge monitor 11a to blink using the charge monitor control unit 43 (step S15).
If the battery 3 is not at the end of its life, the control circuit 27 uses the charge monitor control unit 43 to turn on the charge monitor 11a with the reference brightness setting (step S4). Here, the reference brightness is as described in FIG.
In step S5, the operator determines whether the brightness of the charge monitor 11a is just right. When the operator determines that the brightness of the charging monitor 11a is just right, the operator does not operate the remote controller 13 and the setting of the brightness of the charging monitor 11a is completed (step S12).

  If the operator does not determine in step S5 that the brightness of the charge monitor 11a is just right, the operator presses the monitor brightness adjustment button 15e of the charge monitor 11a once (step S6). In this case, the remote controller 13 generates and transmits a brightness reduction signal. The control circuit 27 receives the brightness reduction signal via the receiving circuit 35 and the signal receiving unit 36. When receiving the brightness reduction signal, the control circuit 27 turns on the charge monitor 11a using the charge monitor control unit 43 (step S7).

In step S8, the operator determines whether the brightness of the charge monitor 11a is just right. When the operator determines that the brightness of the charging monitor 11a is just right, the brightness setting of the charging monitor 11a is terminated without operating the remote controller 13 (step S12).
If the operator does not determine in step S8 that the brightness of the charge monitor 11a is just right, the operator presses the monitor brightness adjustment button 15e of the charge monitor 11a again (step S9). In this case, in the remote controller 13, the generation unit 15-1 generates a brightness increase signal that requests an increase in the brightness of the charging monitor 11 a that is a monitor light source, and the transmission unit 16 transmits a brightness increase signal. . When the signal reception unit 36 receives a brightness increase signal from the remote controller 13, the control circuit 27 turns on the brightness of the charge monitor 11a brightly (step S10).

In step S11, the operator determines whether the brightness of the charge monitor 11a is just right. When the operator determines that the brightness of the charging monitor 11a is just right, the brightness setting of the charging monitor 11a is terminated without operating the remote controller 13 (step S12).
If the worker does not determine in step S11 that the brightness of the charge monitor 11a is just right, the process proceeds to step S6, and the above process is repeated. The above process is repeated because the operator changes the brightness of the charging monitor 11a as the environment where the charging monitor 11a is installed becomes darker or brighter.

  When the control circuit 27 receives a brightness reduction signal or a brightness increase signal, there are several means for changing the brightness of the monitors 11. For example, as shown in FIGS. 10 and 11, for each current limiting element 50 of the monitor 11, the brightness changeover switch element 52 is turned on or off by the monitor brightness control unit 51 to change the connection of the current limiting element 53. You can change the brightness. 10 and 11, only the charge monitor 11a shows the current limiting element 53, but the current limiting element 53 and the brightness changeover switch element 52 for the current limiting element 50 of the lamp monitor 11b and inspection monitor 11c are omitted.

  In terms of circuit, the monitors 11 are collectively made as shown in FIG. 12, so that the brightness of the charge monitor 11a, the lamp monitor 11b, and the inspection monitor 11c is controlled by a set of current limiting elements 53 and brightness changeover switch elements 52. It can be changed.

Further, as shown in FIG. 13, by changing the signal of the charge monitor control unit 43 to an output such as PWM, the brightness can be changed without connecting any external components.
FIG. 13 shows the operation of the charge monitor control unit 43. As the brightness corresponding to FIG. 5, the reference brightness, the PWM signal in each case when the monitor is darkened, and when the monitor is brightened are shown. ing. It is generally known as a dimming method by changing the power of the LED to change the brightness of the LED by blinking at a speed invisible to human eyes by PWM control.

  When the confirmation button 15a is operated, the monitor 11 can be easily confirmed by making the monitor 11 brighter than “reference brightness”.

  When the operator presses the monitor brightness adjustment button 15e and transmits a brightness reduction signal to the monitor device 100, the brightness setting of the charge monitor 11a becomes dark, so that the guest can comfortably stay at bedtime. Further, when the confirmation button 15a is operated as described above, the monitors 11 are set to be brighter than the “reference brightness”, so that the inspector checks the emergency light 1 for a predetermined time. The monitor can be lit brightly. Therefore, the monitor brightness adjustment button 15e and the confirmation button 15a can make the monitors 11 have a brightness that satisfies both the user and the inspector.

  Although the emergency light 1 includes a lamp monitor 11b, the lamp monitor 11b is lit in red when the lamp 6 is abnormal, and is a monitor for notifying that the lamp 6 is abnormal. If the red lamp monitor 11b is lit, the guest feels uncomfortable at bedtime. The brightness of the monitors 11 can be set in advance even before blinking or lighting. Also regarding the lamp monitor 11b, the brightness setting of the lamp monitor 11b can be reduced by transmitting a brightness reduction signal from the monitor brightness adjustment button 15e to the monitor device 100 in advance. It is possible to set the brightness setting of the lamp monitor 11b in advance to a “darker” setting than the “reference brightness” setting. With this setting, when an abnormality of the lamp 6 is detected, the lamp monitor 11b is lit darker than “reference brightness”. As for the lamp monitor 11b, when the confirmation button 15a is operated, the control circuit 27 turns on the lamp monitor 11b to be brighter than “reference brightness” or “reference brightness”. Even when the lamp monitor 11b is bright and difficult to see, the state of the monitor can be reliably confirmed.

*** Explanation of effects of embodiment 1 ***
According to the monitor device 100 of the first embodiment, when the control circuit 27 receives the brightness reduction signal, the control circuit 27 darkens the light emission state of the monitors 11 indicating the state of the emergency light 1 that is a device. Therefore, a possibility that the guest feels uncomfortable about the brightness of the monitors 11 can be reduced.

Embodiment 2. FIG.
The second embodiment will be described with reference to FIGS. The second embodiment relates to the button arrangement on the surface of the main body 14 of the remote controller 13. In the first embodiment, the remote controller 13 including the monitor brightness adjustment button 15e is shown in FIG.
FIG. 14 is a comparative example of the remote controller 13 according to the second embodiment described with reference to FIGS. 15 and 16. Since the configuration of the remote controller 13 in FIG. 14 is the same as that of the remote controller in FIG. 4 except for the appliance changeover switch 17, only the appliance changeover switch 17 will be described. In the remote control 13 shown in FIG. 14, an appliance changeover switch 17 is installed on the back side of the main body 14 so that it can be selectively used for an emergency light or a guide light. Channel 1 is used for a guide light, and channel 2 is used for an emergency light. As described above, the emergency light and the guide light have similar operations but are different products. Therefore, when performing the inspection operation, it is necessary to separate signals transmitted from the remote control for the emergency light and the guide light. In other words, when an operator mistakenly uses the appliance changeover switch 17 in the guide light channel 1 to check the emergency light, the guide light installed in the vicinity is lit in an emergency, and continues for a specified time or longer. There was concern that they could not go to self-check because they were not charged.

  FIG. 15 is a diagram showing the remote controller 13 of the second embodiment that eliminates this concern. FIG. 15 shows the button arrangement on the remote controller 13. In order to eliminate the above-described concern in the remote controller 13 of the second embodiment, the surface of the main body portion 14 is provided with a first arrangement area 14-1 in which a plurality of buttons used for a guide lamp as a first device are arranged, A second arrangement area 14-2 in which a plurality of buttons used for an emergency light, which is a second device, is arranged, and a monitor that causes the generation unit 15-1 of the remote control 13 to generate a brightness reduction signal and a brightness increase signal. It is divided into a third arrangement area 14-3 in which the brightness adjustment button 15e is arranged.

Even in the case of a guide light, there are cases where it is desired to adjust the brightness of the monitors 11. For this reason, the remote controller 13 of FIG. 15 has a configuration including a third arrangement region 14-3 in which a monitor brightness adjustment button 15e, which is a button common to the emergency light and the guide light, is arranged. In FIG. 15, the third arrangement area 14-3 is arranged below the remote control body below the first arrangement area 14-1 and the second arrangement area 14-2.
FIG. 16 shows different arrangements of FIG. 15 and the third arrangement region 14-3. In FIG. 16, the third arrangement area 14-3 is arranged between the first arrangement area 14-1 and the second arrangement area 14-2. The third arrangement area 14-3 may be located between the first arrangement area 14-1 and the second arrangement area 14-2 as a common button instead of below the remote control main body. You may arrange | position above a remote control main body rather than 14-1 and the 2nd arrangement | positioning area | region 14-2.

  When the operator presses the self-inspection switch 10 of the emergency light 1 or the operator presses the self-inspection button 15b of the remote controller 13 and a self-inspection signal is transmitted from the remote controller 13, the control circuit 27 indicates that the confirmation button 15a of the remote controller 13 is The same “operation of the monitor 11” as when operated. As a result, it is possible to clearly notify the inspector when 48 hours of continuous charging has not been performed, and even when the self-inspection button is accidentally pressed, interruption of continuous charging time due to transition to unnecessary emergency lighting is prevented. be able to.

*** Effects of Embodiment 2 ***
As described above, the surface of the main body 14 of the remote controller 13 is divided into the first arrangement area 14-1, the second arrangement area 14-2, and the third arrangement area 14-3, so that the inspector and Convenience can be achieved for people in locations where emergency lights or guide lights are installed.

Embodiment 3 FIG.
The third embodiment will be described with reference to FIGS. In the third embodiment, the case where the monitor device 100 uses the illuminance sensor 61 will be described. In the first and second embodiments, the example of the brightness operation of the monitor 11 when the remote controller 13 is used centering on the emergency light is shown. However, it is inconvenient in practice because the monitor 11 is set to be dark by the operator who manages the emergency light 1 and the guest cannot darken the monitor 11. Therefore, in the third embodiment, the illuminance sensor 61 detects the illuminance, and the control circuit 27 darkens the brightness of the monitors 11 based on the detected illuminance. The illuminance sensor 61 that detects brightness is a transmission device that transmits a brightness reduction signal and a brightness increase signal.
(1) The illuminance sensor 61 detects the illuminance of the room when the guest turns off the room illumination at bedtime.
(2) The illuminance sensor 61 outputs a detection signal to the control circuit 27 via the sensor receiver 62 which is a signal receiver.
(3) The control circuit 27 darkens the monitors 11 when the detection signal received via the sensor receiver 62 exceeds the threshold value. In this case, it is assumed that the detection signal output from the illuminance sensor 61 has a larger value as it becomes darker.

  Since the control circuit 27 darkens the monitors 11 based on the detection signal of the illuminance sensor 61, the monitor of the emergency light 1 when the outdoors are dark or when the illumination is turned off due to the absence of a person. 11 can be darkened. When the inspector enters the room, when the surroundings are dark, it is easy to check the monitors 11 even if the monitors 11 are dark. Even in this case, if it is difficult for the operator to check the monitors 11, the monitor brightness adjustment button 15 e may be used to set the reference brightness from the current dark state or brighter than the reference brightness. No problem.

FIG. 17 shows a perspective view of the emergency light 1 when the illuminance sensor 61 is provided. The emergency light 1 in FIG. 17 is provided with an illuminance sensor 61 with respect to the emergency light 1 shown in FIG. A hole for the illuminance sensor 61 is formed in the frame 5, and the illuminance sensor 61 is exposed from the hole.
FIG. 18 is a block diagram of the emergency light 1 when the illuminance sensor 61 is provided. FIG. 18 is different from FIG. 7 in that the emergency light 1 includes an illuminance sensor 61, and the control circuit 27 includes a sensor reception unit 62 that is a signal reception unit that receives a detection signal output from the illuminance sensor 61. Is different.
The control circuit 27 receives the detection signal output from the illuminance sensor 61 via the sensor receiver 62. The control circuit 27 compares the detection signal with the threshold value, and when the detection signal exceeds the threshold value, the charge monitor control unit 43 and the lamp monitor control unit 44 are controlled so that the charge monitor 11a and the lamp monitor 11b are lit darker than the current level. Let In this case, the detection signal exceeding the threshold value is a brightness reduction signal. The control circuit 27 has a nonvolatile memory, and the threshold value is stored in the nonvolatile memory.
On the other hand, when the surroundings of the illuminance sensor 61 become bright and the detection signal received by the control circuit 27 is equal to or less than the threshold value, the control circuit 27 controls the charge monitor control unit 43 and the lamp monitor control unit 44 to control the charge monitor 11a and The lamp monitor 11b is turned on brightly as before. In this case, the detection signal below the threshold is a brightness increase signal.

  FIG. 19 is a flowchart illustrating the operation of the monitor device 100 according to the third embodiment. The operation of the monitor device 100 according to the third embodiment will be described with reference to FIG.

In step S21, the control circuit 27 uses the power failure detection circuit 48 to determine whether or not there is a power failure. In the case of a power failure, the process proceeds to step S28, and the control circuit 27 performs emergency lighting. If it is not a power failure, the process proceeds to step S22.
In step S22, the control circuit 27 uses the battery voltage detection unit 42 to determine whether or not the battery 3 is present and charging is in progress. If not, the process proceeds to step S29, and the control circuit 27 turns off the charge monitor 11a using the charge monitor control unit 43. If the battery is being charged, the process proceeds to step S23, and the control circuit 27 uses the battery voltage detection unit 42 to determine whether or not the battery 3 has a lifetime. If the battery 3 has a lifetime, the process proceeds to step S30.

In step S <b> 30, the control circuit 27 checks the ambient brightness using the illuminance sensor 61. In step S31, the control circuit 27 determines whether or not the charge monitor 11a is too bright. This determination is a determination using the threshold described above. If it is determined that the brightness is too bright (YES in step S31), the control circuit 27 causes the charge monitor 11a to blink darkly (step S32). If it is determined that it is not too bright (NO in step S31), the control circuit 27 causes the charge monitor 11a to blink at the reference brightness (step S33).
If battery 3 is not at the end of life (NO in step S23), the process proceeds to step S24.

In step S24, the control circuit 27 checks the ambient brightness using the illuminance sensor 61, as in step S30.
In step S25, as in step S31, the control circuit 27 determines whether or not the charge monitor 11a is too bright. When it determines with it being too bright (it is YES at step S25), the control circuit 27 makes the charge monitor 11a light darkly (step S27). If it is determined that it is not too bright (NO in step S25), the control circuit 27 turns on the charge monitor 11a with the reference brightness (step S26).

*** Effects of Embodiment 3 ***
According to the emergency light 1 of the third embodiment, the monitor 11 is practically convenient because the brightness becomes dark as the surroundings of the illuminance sensor 61 become dark regardless of the operation of the operator. is there. In the setting using the remote controller 13, the operator may forget the setting to darken the monitors 11, but there is no such concern when using the illuminance sensor 61.

Embodiment 4 FIG.
The fourth embodiment will be described with reference to FIGS. Embodiment 4 demonstrates the case where the monitor apparatus 100 is applied to a guide light.

In the first to third embodiments, the method of darkening the brightness of the monitors 11 using the monitor brightness adjustment button 15e has been described assuming an emergency light installed in a guest room. In addition to emergency lights, the brightness adjustment function of the monitor can be used. For example, in a place such as a movie theater or a theater, the guide light display panel is allowed to be turned off by the administrator during the screening by operating the guide light signal device. However, the charge monitor 11a and the lamp monitor 11b when the lamp is abnormal continue to be lit or blinking. The situation is the same for emergency lights. Since it is not necessary for the viewer to check the monitors 11 such as the charging monitor 11a and the lamp monitor 11b during the screening, it can be said that the viewers need not turn on or blink the monitors 11. Therefore, even if it is a guide light, the monitor brightness adjustment function when the monitor brightness adjustment button 15e is pressed can be set dark so that the monitor brightness 11 does not stand out when it is unnecessary. If so, there will be no hindrance to the viewer's appreciation.
In the fourth embodiment, the brightness of the monitor 11 of the guide light is set to be dark by the monitor brightness adjustment function in a place such as a movie theater or a theater.

FIG. 20 is an exploded perspective view of the guide light 71. The guide light 71 is an embedded guide light fixture that is embedded in a mounting hole formed in a wall and installed in the mounting hole. The guide light 71 has an instrument body 74 and a frame 75.
The light source of the guide light 71 is an LED module 76. The LED module 76 is disposed on the display panel 77. A terminal block 78, a lighting unit 72, and a battery 73 are housed inside the instrument body 74. The terminal block 78, the lighting unit 72, and the battery 73 are disposed inside the instrument body 74.

  FIG. 21 is an external view seen from the front of the guide light 71 and an enlarged view of the operation unit 79. In the appearance of the guide light 71, the instrument main body 74, the frame 75, and the display panel 77 can be seen. The LED module 76 is covered with a frame 75, and the LED module 76 is indicated by a broken line. The instrument body 74 is installed in a state of being embedded in a hole formed in the wall, and includes a frame 75 serving as a design surface that covers the hole in the wall.

Under the frame 75, an operation unit 79 similar to the emergency light 1 of FIG. The operation unit 79 includes the following (1) to (4). The following (1) to (4) are the same as the emergency light 1 of FIG.
(1) Check switch 9 for confirming the operation of the guide light 71,
(2) Self-inspection switch 10, which is a switch for automatically performing inspection.
(3) a charge monitor 11a, a lamp monitor 11b, and an inspection monitor 11c, which are monitors 11 for displaying the operating state of the guide lamp 71;
(4) The light receiving unit 12 that receives a radio signal from the remote controller 13.
The operation of the operation unit 79 is the same as that of the emergency light 1. When a signal is transmitted by the monitor brightness adjustment button 15 e of the remote controller 13, the control circuit 27 receives the signal via the light receiving unit 12 and the signal receiving unit 36. The control circuit 27 adjusts the brightness of the monitors 11 according to the signal. The operation flow of the main operation is the same as that of the monitor device 100 described in the first to third embodiments.

  Similarly to the emergency light 1 described in the third embodiment, it is also useful to adjust the brightness of the monitors 11 in conjunction with the detection signal of the illuminance sensor 61 in the guide light 71 as well. In this case, an illuminance sensor 61 is added to the operation unit 79 as shown in FIG. The operation of the guide light 71 using the illuminance sensor 61 is the same as that of the monitor device 100 of the emergency light 1 described in the third embodiment.

*** Effects of Embodiment 4 ***
According to the guide light of the fourth embodiment, the brightness of the monitors 11 can be reduced by the monitor device 100, so that it is possible to eliminate the possibility that the audience feels the brightness of the monitors 11 unpleasant.

Embodiment 5 FIG.
The fifth embodiment will be described with reference to FIGS. In the guide light, as described in the fourth embodiment, the manager is allowed to turn off the display panel 77 during the screening by operating the guide light signal device. It is also possible to turn off the LED module 76 that causes the display panel 77 to emit light at the time of performance with a turn-off signal that turns off the LED module 76 and to darken the monitors 11. In the fifth embodiment, when the control circuit 27 of the monitor device 100 receives a turn-off signal instructing to turn off the LED module 76, the control module 27 darkens the brightness of the monitors 11 in addition to turning off the LED module 76. That is, the control circuit 27 controls the brightness of the lamp 6 that is a light source for emitting light that causes the display panel 77 to emit light. The control circuit 27 turns off the lamp 6 and sets the brightness of the charge monitor 11a, which is a monitor light source, when the turn-off control circuit 203, which is a signal receiving unit, receives a turn-off signal that instructs the lamp 6 to turn off. Is set to be darker than the brightness setting immediately before reception of the turn-off signal. When the light-off signal is received, it means immediately before the light-off signal is received. The guide light 71 corresponds to a “device” of a monitor light source that notifies the state of the device by a light emission state.

  FIG. 23 shows the lighting and blinking states of the monitors 11 of the guide light 71. Specifically, FIG. 23 shows a self-inspection display, a normal charge, a battery failure in the case of “life” or “detached, damaged”, a lamp in the case of “life” or “detached, damaged”. The monitor displays of the charge monitor 11a, the lamp monitor 11b, and the inspection monitor 11c in an abnormal state, an inspectable state, and an inaccessible state are shown. In the case of the guide light 71, as compared with the emergency light 1 of FIG. 8, “life time” is further included when the lamp is abnormal.

FIG. 24 is a block diagram of the circuit in this case. The battery 73 in FIG. The LED module 76 in FIG. When the monitor device 100 provided in the guide light 71 shown in FIG. 24 receives a turn-off signal, the monitor 11 is made darker in addition to turning off the LED module 76.
Since the guide lamp 71 lights the display panel 77 during normal use, the lighted portion is different from the block diagram of the emergency light 1 shown in FIG. 7, but the other portions are the same as those in FIG.

  Only parts different from the emergency light 1 of the first embodiment will be described. The guide lamp 71 that lights the lamp 6 during normal operation operates as follows.

The first DC-DC converter 23 generates an output for lighting the lamp 6 during normal use by the diode 201 and the electrolytic capacitor 202, and supplies the output to the lamp 6 via the normal lamp switch 207. Since the lamp 6 is connected to the second DC-DC converter 29 that supplies power in an emergency, the output is separated by the OR circuit 208 as necessary.
The turn-off signal for turning off the guide light 71 branches from the commercial power supply AC21, and the display panel is turned off during the screening by the operation of the guide light signal device by the administrator as described above. This operation corresponds to turning off the extinguishing switch 205. The turn-off detection circuit 204 detects that the turn-off switch 205 is turned off. When it is detected that the turn-off switch 205 is turned off, the turn-off detection circuit 204 outputs a turn-off signal. The extinction control circuit 203 is a signal receiving unit. When the control circuit 27 receives the turn-off signal via the turn-off control circuit 203, the control circuit 27 outputs a signal from the normal lamp lighting control unit 206 that controls the lighting of the normal lamp, and turns off the normal lamp switch 207. As a result, the lamp 6 is turned off. At this time, the control circuit 27 adjusts the monitors 11 to a brightness that does not hinder the screening and performance by darkening the monitors 11 simultaneously with turning off.

  FIG. 25 is a flowchart showing the operation of the guide light 71. With reference to FIG. 25, operation | movement of the guide light 71 of Embodiment 5 is demonstrated. The main body of the operation in FIG. 25 is the control circuit 27.

In step S31, the control circuit 27 uses the power failure detection circuit 48 to determine whether there is a power failure. In the case of a power failure, the process proceeds to step S37, and the control circuit 27 performs emergency lighting. If it is not a power failure, the process proceeds to step S32.
In step S32, the control circuit 27 uses the battery voltage detection unit 42 to determine whether or not the battery 3 is present and charging is in progress. If charging is not in progress, the process proceeds to step S38, and the control circuit 27 turns off the charging monitor 11a using the charging monitor control unit 43. If the battery is being charged, the process proceeds to step S33, and the control circuit 27 uses the battery voltage detection unit 42 to determine whether the battery 3 is at the end of its life. If the battery 3 is at the end of its life, the process proceeds to step S39, and the control circuit 27 determines whether to turn off the display panel 77, that is, whether to turn off the lamp 6. The control circuit 27 turns off the lamp 6 when the turn-off signal is received as described above.
When the lamp 6 is turned off, the control circuit 27 turns off the lamp 6 and causes the charge monitor 11a to blink darkly (step S40). When the lamp 6 is not turned off, the charging monitor 11a is blinked with the reference brightness (step S41).

If battery 3 is not at the end of its life, the process proceeds to step S34.
In step S34, the control circuit 27 determines whether the lamp 6 is turned off. When the lamp 6 is turned off, the control circuit 27 turns off the lamp 6 and turns on the charging monitor 11a darkly (step S35). When the lamp 6 is not turned off, the charging monitor 11a is turned on with the reference brightness (step S36).
In the monitoring operation of the emergency light 1, the emergency light 1 that is easy to use and safe can be realized by combining the operation with the remote controller 13 and the operation in conjunction with the sensor. In the monitoring operation of the guide light 71, an easy-to-use and safe guide light 71 may be realized by combining the operation with the remote controller, the operation in conjunction with the illuminance sensor, and the operation of the turn-off switch 205. In the second embodiment, it has been described that there is no erroneous operation by dividing the button arrangement area of the remote controller 13. However, if a simple button arrangement as shown in FIG. 14 is desired, the brightness of the monitors 11 may be changed by long-pressing the confirmation button 15a. The long press is, for example, 2 seconds or more.
Regarding the confirmation button 15a,
(1) The brightness becomes normal when the normal button is pressed. (2) Next, press and hold for 2 seconds or more and release the button to increase the brightness.
(3) Next, press and hold for more than 2 seconds, it will darken when you take your hand off the button,
(4) The monitor 11 may be configured to be set to an appropriate brightness by pressing the button several times in the normal brightness state of (1) above.

  Note that the lamp 6 is not limited to the LED, and various light sources may be used in addition to the organic EL. The lighting unit 2 may be provided with a lighting circuit that matches the type of light source.

*** Effect of Embodiment 5 ***
According to the guide light of the fifth embodiment, the monitor device 100 darkens the brightness of the monitors 11 in conjunction with turning off the light source when a turn-off signal is detected. In addition, it is possible to eliminate the possibility that the audience feels uncomfortable with the brightness of the monitors 11. Further, since the monitor device 100 darkens the brightness of the monitors 11 in conjunction with turning off the light source, both the light can be turned off by one operation and the monitors 11 can be darkened.
