Description

  The present invention relates to a guide light device.

  Conventionally, in a guide lamp device, a light source is turned on by always being supplied with power from a commercial power source, and a battery is normally charged with power from the commercial power source. In an emergency when power supply from the commercial power supply is interrupted, the light source is turned on by power supply from the battery.

  As described above, in the guide light device, it is most important that the light source is surely turned on so that a person can be guided in an emergency, and therefore, it is obliged to periodically check various items.

  One of the items to be regularly inspected is whether the light source is turned on for a predetermined time (for example, 20 minutes) by supplying power from the battery (hereinafter referred to as “emergency inspection”). It is known to perform by manipulating. In such an emergency check, the battery life is detected when the check switch is operated, and when it is determined that it is time to replace the battery, the replacement of the battery is encouraged to supply the power from the battery unit for a predetermined time. This is a technique for maintaining lighting (see, for example, Patent Document 1).

On the other hand, in the case of an emergency inspection using an inspection switch as described in Patent Document 1, the applicant of the present application is provided with an external device in order to reduce the trouble that an inspection operator must operate the inspection switch directly. We have applied for technology related to emergency inspection using a remote control terminal as a transmitter. According to this, since the arithmetic and control unit automatically switches to the emergency check mode in response to a check command from the external transmitter and detects the battery voltage or the like, the check work can be simplified (for example, see Patent Document 2). .
JP-A-6-328601 JP 2003-92013 A

  Such a technique described in Patent Document 2 is preferably capable of performing an emergency check using an external transmitter as far as possible from the guide light device.

  That is, for example, when the guide light device is directly attached to the wall surface, an emergency inspection is performed by an external transmitter from the front of the guide light device rather than going directly below the guide light device directly attached to the wall. This is because the movement range of the inspection worker may be smaller if the inspection can be started, and contributes to further efficiency of the inspection operation.

  In the emergency inspection method using an external transmitter, if the position where the external inspection can be started by the external transmitter is a position where the guide indicator of the guide light device cannot be visually recognized (that is, directly under the guide light device), It is also assumed that it is difficult to determine whether or not the mode has been started. That is, as a means for easily confirming whether or not the guide light device is in the emergency check mode, the emergency check mode is started in a state where the guide display body can be visually recognized. This is because, in general, the brightness of the guide display device at the normal time of the guide light device and the brightness at the time of emergency are set to be lower in the emergency time. By confirming that the brightness of the guidance display body has been reduced, the operator can easily recognize that the emergency lighting operation has been performed. Therefore, it is preferable that an emergency check can be performed on the guide display body of the guide light device from an obliquely lower side using an external transmitter.

  In general, since the guide light device is installed at a high place, a heavy battery is often placed on the bottom of the peripheral frame portion in consideration of a weight balance and so on. Arranged at the bottom. That is, when applying the technique described in Patent Document 2, simply placing the receiving unit and the transmitting unit at the bottom of the peripheral frame portion cannot secure the arrangement space. There was also a risk of it.

  The present invention has been made in view of the above, and an object of the present invention is to provide a guide light device that can efficiently perform an emergency check and can prevent an increase in the size of an instrument body.

  According to the guide light device of claim 1, a light source; a battery; a fixture main body having a rectangular peripheral frame portion and having a guide display body on at least one opening side of the peripheral frame portion; A lighting unit that always turns on the light source by power supply from a commercial power supply and lights the light source by power supply from a battery in an emergency to illuminate the guidance display; provided on the opening side at the bottom of the peripheral frame, and externally A receiving unit that receives a signal from the transmitter; an inspection control unit that controls the lighting unit to enter an inspection mode in which a light source is turned on by power supply from the battery when an inspection start signal is input via the receiving unit; A transmitter that is provided at the bottom of the peripheral frame so as to be juxtaposed with the receiver in a direction opposite to the opening side of the main body, and that transmits a signal to the outside. It is characterized by being That.

  In the present invention and the following inventions, definitions and technical meanings of terms are as follows unless otherwise specified.

  The light source may be in any form such as a point light source, a linear light source, and a surface light source, and may further provide any light emitting action such as a fluorescent lamp, LED, and organic EL.

  In addition, the light source may be configured to be provided not only in the instrument main body to be described later but also outside the instrument main body. In short, any configuration may be employed as long as it is configured to illuminate the guidance display.

  The peripheral frame portion of the instrument main body is not integrally formed as in the case of a guide light device generally called 3: 1 in addition to the one that continuously forms an integral frame portion. What comprises the member which forms a surrounding frame is also contained.

  The guidance display body is formed so that the symbol of the guidance display body can be visually recognized by the irradiation light from the light source, but the irradiation light from the light source may be either direct or indirect.

  The receiving unit and the transmitting unit are disposed on the peripheral frame portion of the instrument body, but the receiving unit is disposed on the guidance display body side with respect to the transmitting unit. Further, the phrase “provided on the opening side of the bottom part of the peripheral frame part” of the receiving part means that the central part of the receiving part is located on the opening part side of the center line in the longitudinal direction of the bottom part. . The transmitter may not be closer to the opening than the center line in the longitudinal direction of the bottom.

  The "inspection mode" is an emergency inspection, light source lighting state inspection, light source life inspection, power supply terminal block and power line connection state inspection, and other desired inspection items. There is no need to check the appropriate matters according to the usage form.

  According to the first aspect of the present invention, for example, when an inspection is performed using an external transmitter, an operator transmits an inspection mode start signal from the transmitter. Next, when this signal is received by the receiving unit, the lighting unit is controlled so that the inspection control unit enters the inspection mode, and the inspection result of the inspection control unit is stored in, for example, the storage unit. When the inspection result confirmation signal from the transmitter is received by the receiving unit, the inspection result stored in the storage unit or the like is transmitted from the transmitting unit to the outside, and the signal is received by the transmitter to obtain information on the inspection result. It can be grasped with a transmitter.

  At this time, the receiving part is provided so as to be on the opening side of the bottom part of the peripheral frame part. That is, since the guide display body is disposed in the opening of the instrument body, the width of the guide lamp device is the sum of the width of the instrument body and the width of the guide display body. However, as described above, even if the guide display body is arranged in the opening, the receiver is positioned on the guide display body side of the guide light device, so that the operator can connect the external transmitter to the guide display body side. Even when operated from an obliquely lower position of the guide light device, the receiving unit is disposed at a position that is relatively easy to receive. Therefore, when checking the emergency check mode, the operator does not look into the lower part of the guide light device and can perform while visually checking the guide indicator, so that the efficiency of the check work is very good. Become.

  Further, when receiving a reply signal from the transmission unit, there is no need for the operator to visually recognize the guidance display body because the worker confirms the content of the reply signal with an external transmitter, for example. Therefore, for example, when confirming the inspection result using an external transmitter, the operator may return a signal from the transmission unit located almost directly below the guide lamp device, and the transmission unit may You may arrange | position in the space | interval location. Furthermore, the transmitter can also be arranged in parallel in the direction parallel to the longitudinal direction of the receiver and the bottom of the peripheral frame (that is, arranged side by side with the receiver), but at the bottom of the peripheral frame In this case, a relatively heavy and large battery, a check switch and the like must be arranged, and the arrangement space is limited. Therefore, if the transmitting unit and the receiving unit are simply arranged in parallel to the longitudinal direction of the bottom part of the peripheral frame part, the longitudinal direction of the bottom part of the peripheral frame part may have to be further extended. The main body will be enlarged. Therefore, if the transmitter is arranged in parallel in the direction parallel to the short direction of the receiver and the bottom, it is possible to prevent the instrument body from being enlarged.

  According to the first aspect of the present invention, even if the guidance display body is disposed on the instrument body, the signal from the external transmitter from the guidance display body side can be easily received by the receiving unit. The start can be confirmed by the luminance change of the guidance display body, and the inspection work can be carried out efficiently. Moreover, even if it has a receiving part and a transmission part, it can prevent that an instrument main body enlarges.

The inspection switch 5 and the LEDs 7 and 7 of the housing 50 are arranged so as to face the external report from the third and fourth holes 93 and 94 of the bottom 91A of the instrument body 9.

  As shown in FIG. 3, the transmission / reception unit 70 is provided with a transmission unit 72 so as to be exposed from the bottom 71, and is provided with a reception unit 73 on the back side from the bottom 71. And the transmission part 72 and the receiving part 73 are accommodated in the area | region divided in the bottom part 71 of the transmission / reception unit 70, as shown in FIG.

  Further, as shown in FIG. 1, the transmission / reception unit 70 is placed and fixed on the bottom 91 </ b> A of the instrument main body 9.

It is formed so as to be displaced from the center to the guidance display 8 side. That is, the width of the guide light device 1 is the sum of the width of the fixture body 9 (the dimension in the short direction of the bottom portion 91A) and the thickness of the guide display body 8. Even in such a case, the first hole portion 92 </ b> A is not disposed in the depth direction with respect to the guidance display body 8.

  And it arrange | positions so that the receiving part 73 and the transmission part 72 of the transmission / reception unit 70 may face with respect to each 1st, 2nd hole part 92A, 92B arrange | positioned in this way. The casing 50 and the transmission / reception unit 70 are electrically connected to the lighting unit 10 in the lighting unit storage box 2 through wiring.

  Next, the circuit configuration of the guide lamp device 1 of the present embodiment will be described with reference to FIG.

  The lighting unit 10 includes a regular lighting circuit 14, a battery circuit 15, an oscillation control unit 16, an inverter circuit 17, a control unit 19, and the like, and power from the commercial power supply 11 is input to the rectifier circuit 12 and passes through the transformer 13. To the regular lighting circuit 14 and the battery circuit 15. The regular lighting circuit 14 is controlled by the oscillation control unit 16, converts the power input via the transformer 1 into high frequency power by the inverter circuit 17, and supplies lighting power to the light source 3.

  The oscillation control unit 16 is controlled based on a control command from the lighting control unit 19A of the control unit 19, and causes the light source 3 to be lit at a high frequency by the normal lighting circuit 14 in the normal lighting mode. Although not shown, the inspection switch 5 is also connected to the lighting unit 10.

  On the other hand, the battery circuit 15 supplies power from the battery 20 to the light source 3 via the inverter circuit 17 in the event of an emergency of the commercial power supply 11 to turn on the light source 3. In the regular lighting mode, the battery circuit 15 The battery 20 is charged with electric power. When the commercial power supply 11 is in an emergency such as a power failure, the lighting control unit 19A outputs an operation command to the battery circuit 15 and supplies the charging power of the battery 20 to the inverter circuit 17. Thereby, at the time of a power failure of the commercial power supply 11, the charging power from the battery 20 is high-frequency converted by the inverter circuit 17 and supplied to the light source 3. Thereby, even if it is a case where the commercial power source 11 carries out a power failure, lighting of the light source 3 of the guide lamp apparatus 1 can be continued. In this emergency lighting, the light output of the light source 3 is smaller than that in the regular lighting mode. This is because the purpose is to maintain the power of the battery 20 for as long as possible, and it is set so that the required minimum light output is obtained. Therefore, the operation of the light source 3 when switching from the regular lighting mode to the emergency lighting mode is “all-light lighting → light-off momentarily → dimming lighting”.

  The inspection unit 18 includes a reception unit 73 that receives a signal of an inspection start command from a remote control terminal 60 that is an external transmitter, and a transmission unit 72 that transmits the inspection result. When the inspection start signal from the remote control terminal 60 is received by the receiving unit 73, an inspection start command is input to the inspection control unit 19B via the inspection unit 18, so that the inspection control unit 19 enters the emergency inspection mode. The lighting control unit 19A is controlled as described above.

  Then, the lighting control unit 19A in the emergency check mode outputs a command to the oscillation control unit 16 so that the light source 3 is not lit by supplying power from the regular lighting circuit 14 and from the battery 20 of the battery circuit 15. An operation command is output so as to supply charging power to the inverter circuit 17. Thereby, it becomes a simulated power failure state and becomes an emergency check mode. Then, after a predetermined time (for example, 20 minutes) elapses or during a predetermined time elapses, the battery voltage, the lamp lighting state, and the like are detected, and the detection results are stored in the storage means 61.

  After completion of the emergency check mode, the lighting control unit 19A outputs an operation command to the oscillation control unit 16 to operate the normal lighting circuit 14, and also stops discharging of the battery 20 and returns to the normal lighting mode. Become.

  Further, after the emergency inspection mode is completed, when the information acquisition command signal (signal for confirming the inspection result) of the remote control terminal 60 is received by the reception unit 73, the inspection result stored in the storage unit 61 is output from the transmission unit 73. It has become so. Then, the inspection result is displayed on the display unit of the remote control transmitter 60, and the operator can confirm the inspection result.

  According to the present embodiment, the receiving unit 73 is provided on the opening 98 side of the bottom 91 </ b> A of the peripheral frame 91. That is, the width of the guide lamp device 1 is the sum of the width of the fixture body 9 (the dimension in the short direction of the bottom portion 91A) and the plate thickness of the guide display body 8. Even in such a case, the receiver 73 The first hole 92 </ b> A that faces the guide display body 8 is not disposed in the depth direction. Therefore, even if the guide display 8 is disposed in the opening 98, the receiver 73 is positioned on the guide display body side of the guide lamp device 1, so that the operator can connect the remote control terminal 60 to the guide lamp device. Even if it is a case where it operates from the diagonally lower position of the 1 guidance display body 8 side, it is easy to receive in the receiving part 73. With such a configuration, it is possible to confirm whether or not the mode has shifted to the emergency inspection mode while visually recognizing the luminance change of the guidance display body 8, and thus the efficiency of the inspection work can be greatly increased.

  Moreover, since the transmission part 72 is for returning the inspection result to the remote control terminal 60, it is not necessary for the operator to visually recognize the guidance display body 8 when the reply signal from the transmission part 72 is received. In addition, when confirming the inspection result using the remote control terminal 60, it is more reliable that the operator returns a signal from the transmission unit 72 at a position substantially directly below the guide lamp device 1. May be easily obtained. That is, if a signal from the transmission unit 72 can be received even from a relatively long distance, a reply signal from a guide light device different from the guide light device 1 that is desired to obtain the inspection result may be transmitted. Because. Therefore, there are cases where the checking operation of the inspection result is preferably performed in the vicinity immediately below the guide light device 1 so that a signal from the target guide light device 1 can be reliably obtained. Therefore, the transmission unit 72 may be disposed at the position of the bottom 91 </ b> A that is separated from the guidance display body 8.

  The transmitter 72 can also be arranged in parallel in the direction parallel to the longitudinal direction of the receiver 91 and the bottom 91A of the peripheral frame 91 (that is, arranged side by side with the receiver 73). Since a member such as the casing 50 provided with the relatively heavy and large battery 20 and the inspection switch 5 is arranged on the bottom 91A of the 91, the arrangement space is limited. Therefore, if the transmission / reception unit 70 is simply arranged so that the transmission unit 72 and the reception unit 73 are arranged side by side in a direction parallel to the longitudinal direction of the bottom 91A of the peripheral frame 91, the bottom of the peripheral frame 91 is obtained. There is a possibility that the longitudinal direction of 91A must be further extended. Therefore, if the transmitter 72 is arranged in parallel in the direction parallel to the short direction of the receiver 73 and the bottom 91A (the side opposite to the opening 98), the guide lamp device 1 itself can be enlarged. Nor.

  In addition, in the said embodiment, although LED7,7 and the transmission part 72 and the receiving part 73 were formed as a separate unit, when LED7,7 comprises a visible light communication element, for example, the transmission part 72, a receiving part 73 can also be used. This eliminates the need for a new member as an external communication terminal.
