The side panel 62b is, for example, a red color filter, and changes the light color of the light emitted from the light source 3 to red.

  In Japan, operation of the national instantaneous warning system (common name: J-ALERT) has started. As shown in FIG. 2, J-ALERT transmits information (J-ALERT signal) relating to a situation that does not have time to deal with, such as tsunami information and earthquake early warning, using an artificial satellite. Then, emergency information is instantly transmitted from the country to the residents by automatically starting the broadcast disaster prevention administrative radio (broadcast radio) of the municipality. Here, an earthquake disaster is taken as an example. Seismic waves include P waves (longitudinal waves) that cause small-scale fluctuations called initial microtremors and S waves (transverse waves) that cause large fluctuations called main movements. Among these, when a P-wave with a high propagation velocity is detected at a point close to the epicenter, the detection result predicts the propagation of the S wave that comes later in time series. Announce the forecast before reaching a point some distance away from. In the municipal office, a broadcast radio signal is transmitted around the jurisdiction, and the broadcast radio signal is received by the disaster prevention radio, the door-to-door receiver, and the guide light 1. In the guide light 1 of the present embodiment, the emergency warning issuing organization is directly the municipal office described above, and includes various government offices such as the above-mentioned fire department in a broad sense, and the warning signal is a broadcast radio signal. However, in a broad sense, it includes emergency signals other than the J-ALERT signal described above.

  As shown in FIG. 3, the guide light 1 is installed together with a street light 7 that illuminates the road etc. mainly at night. The street light 7 is connected to the commercial AC power supply AC via an EE switch that automatically turns on the street light when the surroundings become dark and automatically turns off the light at a predetermined set time. On the other hand, the guide lamp 1 is charged by a commercial AC power supply AC and connected to an uninterruptible power supply battery 8 that supplies the guide lamp 1 during a power failure. In addition to the transmission / reception unit 2 and the light source 3, the guide light 1 includes a control power source unit 31 that controls a predetermined power source voltage necessary for lighting the light source 3, and a control power source unit 31 when the transmission / reception unit 2 receives an alarm signal. A lamp control interface (I / F) 32 that outputs a flash start signal. Further, the guide light 1 converts a power supply voltage (for example, AC 100V) supplied from the uninterruptible power supply battery 8 into a voltage (for example, DC 5V) required for the lamp control interface 32 and the transmission / reception unit 2. The unit 33 is provided.

  In addition to the antenna 21 described above, the transmission / reception unit 2 includes a transmission / reception circuit unit 22 (see also FIG. 5) that amplifies radio waves received by the antenna 21 and analyzes an alarm signal. In addition, as long as the housing 41 of the lamp body 4 is made of resin, the transmission / reception unit 2 may be housed in the lamp body 4. However, from the viewpoint of physical strength and weather resistance, it is desirable that the casing 41 is made of sturdy metal. In this case, the transmission / reception unit 2 needs to be externally mounted on the lamp body 4. Therefore, the transmission / reception unit 2 of the present embodiment is provided on the surface opposite to the surface on which the direction display unit 5 is provided in the lamp body 4, that is, on the back surface 41 a of the housing 41, so that it has waterproofness and radio wave reception. Particularly preferable from the viewpoint. Moreover, by providing the transmission / reception unit 2 on the back surface 41a of the housing 41, it is possible to prevent the directional display unit 5 on the front surface of the instrument and the side light emitting units 6 on both side surfaces 41d and 41e from being in conflict.

  The control power supply unit 31 includes a lighting circuit for supplying predetermined power to the light source 3. In this lighting circuit, an AC / DC converter that converts an alternating current into a direct current, a capacitor for smoothing, a transformer that generates a required direct current voltage supplied to the light source 3, and the like are provided on a predetermined circuit board (not shown). Mounted). The lamp control interface 32 outputs a flash start signal for lighting the light source 3 in a predetermined lighting pattern based on information included in various emergency warnings from the warning signal analyzed by the transmission / reception circuit unit 22. The lamp control interface 32 may be incorporated in the control power supply unit 31.

  As shown in FIG. 4, the guide light 1 is provided on a pole 9 that holds a street light 7. The pole 9 is not limited to the one dedicated to the street lamp 7 as shown in the figure, and may be a general electric pole, for example. The guide light 1 is provided at a position lower than the street light 7 and easily staying in people's eyes. The street light 7 includes, for example, a light source unit 71, a main body 72 that houses the light source unit 71, and a cover 73 that diffuses and emits light emitted from each LED light source 71 a of the light source unit 71. The street light 7 includes a fixing device 74 that fixes the main body 72 to the pole 9 and is inserted with a power line (not shown) for receiving power supply from the commercial AC power source AC.

  5A to 5D show a more specific configuration of the guide light 1 of the present embodiment. The casing 41 of the lamp body 4 is formed by pressing and cutting a plate material such as a stainless plate or an aluminum plate having a predetermined rigidity into the shape described above. A white paint having a high visible light reflectance is applied to the inner surface of the back surface 41a and both side surfaces 41d and 41e, or a reflective metal material is deposited. The frame body 42 is formed of the same material as that of the housing 41. Between the frame body 42 and the opening of the housing 41, a packing member or the like for preventing water from entering the lamp body 4 may be disposed. In addition, the side light emission part 6 is not restricted to the structure shown in FIG.1 and FIG.5, As shown to Fig.6 (a) thru | or (d), it is the side panel 62a to one rectangular side surface opening part 61a, 61b. , 62b may be provided. Further, for example, the circular side light emitting portion 6 shown in FIG. 5A is provided on one side surface 41d, and the rectangular side light emitting portion 6 shown in FIG. 6C is provided on the other side surface 41e. May be.

  Each light source 3 is connected to a lead wire (not shown). For example, one end of the light source 3 connected in series is led out from one end of the control power source 31 (see also FIG. 3). A light source side connector connected to the output harness through the power source side connector is provided. An end connector is provided at the other end of the light source 3. An input harness is led out from the other end of the control power supply unit 31. Further, a signal line, a ground line, and the like are led out from the other end, and the signal line, the ground line, and the like are taken out from the fixture through an insertion hole (not shown) formed in the lamp body 4. . The signal line is connected to an EE switch that is connected to the commercial AC power supply AC and outputs a signal that instructs the control power supply 31 to switch the output voltage.

  The light source 3 includes a solid-state light emitting element (LED) 3a, an optical member 3b that is provided in the light leading direction of the LED 3a and distributes light emitted from the LED 3a at a wide angle, and a base unit 3c that holds the LED 3a and the optical member 3b. And comprising. The LED 3a is covered with a wavelength conversion member that converts the wavelength of light emitted from the LED chip, and is configured as an LED package. The LED 3a is not particularly limited as long as it is a light source that can emit light of a desired light color as the guide lamp 1, but a YAG phosphor is coated on a GaN blue LED chip that emits blue light having an emission peak wavelength of 460 nm. A so-called white LED is preferably used. For example, the LED 3a is bonded to the mounting surface by a die-bonding material, and each electrode provided on the upper surface of the LED 3a is connected to a land portion provided on the mounting surface using a wire.

  The optical member 3b is a lens formed from a translucent material such as an acrylic resin, a silicone resin, or glass, and is disposed so as to cover the LED 3a. The optical member 3b has a semicircular incident surface on which light emitted from the LED 3a is incident, and an output surface that refracts and emits incident light from the incident surface. The exit surface of the optical member 3b is formed so that the periphery of the normal line passing through the center of the light emitting surface of the LED 3a is concave and the periphery thereof is convex. According to this shape, the concave portion of the exit surface is refracted so that the light diffuses in the outer peripheral direction, and the convex portion of the exit surface is refracted so as to collect the light, and so-called bad wing type light distribution A curve is obtained and light emitted from the LED 3a can be distributed at a wide angle.

  In the guide lamp 1 of the present embodiment, when receiving an alarm signal, each light source 3 is turned on, the light is emitted into the lamp body 4, and is emitted from the display panel 52 in front of the light source 3 to the outside of the lamp. The Further, since the light source 3 has a wide-angle light distribution by the optical member 3b described above, light is emitted also in the lateral direction of the light source 3, and from each side light emitting unit 6 provided on the side surfaces 41d and 41e. Is also emitted. The side light emitting portion 6 provided on the side surface 41d opposite to the guiding direction is provided with a side panel 62a colored in green, and thus emits green light. Further, since the side light emitting unit 6 provided on the side surface 41e in the guiding direction is provided with the side panel 62b colored in red, it emits red light.

  That is, when the person who is evacuating in the event of a disaster sees the guide light 1 from the side and faces the guidance direction, as shown in FIG. Since 6 is visually recognized, it recognizes that it should just go to there like a traffic light. On the other hand, when the person trying to evacuate is facing in the opposite direction to the guidance direction, as shown in FIG. 1 (b), the side light emitting section 6 that emits red light is visually recognized. Recognize that it is not possible. As described above, according to the guide light 1 of the present embodiment, not only the direction indicator 5 provided on the front surface of the guide light 1 but also the side light emission to the side of the guide light 1 that is easily visible to a person traveling on the road. By providing the part 6, the evacuating person can effectively visually recognize the guidance direction. Moreover, as shown in FIG. 4, since both the direction display part 5 and the side light emission part 6 display and light-emit a guidance direction with the light which the light source 3 radiate | emitted, an instrument structure can be simplified. . Further, by using an LED light source as the light source 3, the driving time of the uninterruptible power supply battery 8 can be lengthened, and since the replacement period of the light source is long, labor and cost required for maintenance can be suppressed.

  In addition, as described above, the guide lamp 1 of the present embodiment allows a person facing in the guiding direction to visually recognize one side light emitting unit 6 that emits green light and is facing in the opposite direction to the guiding direction. The other side light emitting portion 6 that emits red light is visually recognized. Thus, if the side light-emitting part 6 shows a guidance direction by light color, even if it is side surface 41d, 41e which is an area smaller than the direction display part 5 in the front of the guide light 1, it will be for the person who evacuates. The guidance direction can be recognized.

  As shown in FIG. 7, a plurality of guide lights 1 configured as described above are provided along a road and used as an evacuation guidance system 10. Here, it is assumed that five guide lights 1a to 1e are installed along the road leading to the evacuation site EP. Each of the guide lights 1a to 1e is turned on in conjunction with an alarm signal transmitted from the emergency alarm issuing organization. At this time, it is visually recognized from the evacuating person M that the side light emitting portions 6 of the guide lights 1b and 1c in the guiding direction (arrows in the drawing) are lit in green, and therefore the direction display portion 5 Even if it is in a position where it is difficult to see, it can be recognized that it is only necessary to proceed in that direction. On the other hand, since it is visually recognized that the side light-emitting portion 6 of the guide light 1a opposite to the guide direction is lit in red, it can be recognized that it should not travel in that direction. As described above, in the guide lamp 1 of the present embodiment, two types of guide information indicating whether the travel is possible or not possible can be displayed because the luminescent colors of the side light emitting units 6 facing each other are different.

  Next, the person M, who has traveled to the vicinity of the intersection CR, recognizes that the guide light 1d in the straight traveling direction of the intersection CR is lit red, and therefore recognizes that the person should not proceed straight through the intersection CR. Can do. Further, when it is visually recognized that the side light emitting portion 6 of the guide lamp 1e on the evacuation site EP side is lit in green, it can be recognized that the direction is the guide direction. These guide lights 1a to 1e are not controlled by a controller placed in an existing disaster prevention facility, but are individually lit in conjunction with an alarm signal. Therefore, for example, even if the guide light 1b shown in FIG. 7 is disabled due to a large-scale earthquake, if the other guide lights 1a and 1c are functioning effectively, the correct guidance direction is given to the person M who is going to evacuate. Can be recognized.

  The guide light which concerns on the modification of the said embodiment is demonstrated with reference to FIG. The guide lamp 1 of this modification further includes an inclination measuring unit 34 that measures the inclination of the lamp body 4. The inclination measuring unit 34 turns off the light source 3 when the inclination of the lamp body 4 exceeds a predetermined threshold. For example, in a large-scale earthquake, for example, the pole 9 for installing the guide light 1 as shown in FIG. 4 may collapse or break, and the guide direction displayed by the guide light 1 is not always accurate. Can happen. At this time, if the light source 3 is turned on and the direction display unit 5 or the side light emitting unit 6 maintains an incorrect display, the evacuating person may be guided in the wrong direction. Therefore, when the inclination of the lamp body 4 exceeds a predetermined threshold, the light source 3 is turned off to stop the guidance direction display itself by the direction display unit 5 or the side light emitting unit 6, thereby evacuating the person. Can be prevented from being guided in the wrong direction.

  Next, a guide light according to a second embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 9, the guide lamp 1 according to the present embodiment includes a side light source 63 serving as a separate light source as the side light emitting unit 6, and a side control power supply unit 64 that supplies power to the side light source 63. . The light source 3 is used exclusively for the direction display unit 5. Other configurations are the same as in the above embodiment.

  In addition, as shown in FIGS. 10A to 10D, the guide light 1 of the present embodiment is provided with the side light emitting portion 6 only on one side surface 41d. Further, a light guide plate is used for the display panel 52 of the direction display unit 5, and a panel light source for introducing light into the display panel 52 from the end face of the display panel 52 is used for the light source 3. One outer surface of the display panel 52 is subjected to diffusion treatment, and light guided while being totally reflected in the display panel 52 is emitted from the outer surface.

  The side light source 63 includes a xenon lamp unit 63a and a lamp cover 63b. In the first embodiment, the light source 3 is used in the direction display unit 5 and the side light emitting unit 6. The light source 3 mainly raises the display of the display panel 52 of the direction display unit 5 to make it easy to see, and does not necessarily require light emission with high output. For this reason, the output of the light emitted from the side light emitting unit 6 is not high. For example, the visibility of the side light emitting unit 6 from a distance cannot be said to be high under conditions where there is a lot of fog or dust.

  On the other hand, according to the guide lamp 1 of the present embodiment, the side light source 63 is provided with the dedicated side light source 63, so that the light output of the side light source 63 can be increased. Visibility of the side light-emitting part 6 from can be improved. Moreover, since the direction display part 5 needs to project the displayed figure etc., while turning on the light source 3 continuously, the side light emission part 6 using the exclusive side light source 63 blinks, for example. By performing the operation control, it is possible to alert the evacuee more.

  In addition, the guide light 1 of the present embodiment is mainly intended to increase visibility and increase the attention of the side light emitting unit 6, and the emission color is not limited to green or red as in the above embodiment. , White or orange may be used. In addition, although the side light emission part 6 is provided only in one side 41d, you may be provided in the other side 41e. In this embodiment, the xenon lamp unit 63 is used as the side light source 63, but an LED lamp unit may be used.

  Next, a guide light according to a third embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 11, the guide light 1 of this embodiment memorize | stores the refuge information set according to the control part 32a which discriminate | determines the kind of warning signal which the transmission / reception part 2 received, and the kind of warning signal. And a storage unit 32b. These are realized by a microcomputer and a memory incorporated in the lamp control I / F 32. Other configurations are the same as in the above embodiment.

  In addition, the guide lamp 1 of the present embodiment includes a display device 5 </ b> A as the direction display unit 5. The display device 5A is configured as an electric display panel, and can display arbitrary characters and figures set in advance in the storage unit 32b. The numbers included in the J-ALERT signal and the broadcast radio signal described above differ depending on the tsunami information, the earthquake early warning, heavy rain (sediment disaster), and the like. Therefore, in the control unit 32a, when the transmission / reception unit 2 receives the warning signal, the type of disaster included in the warning signal is specified, and the direction display as shown in FIG. The display of the unit 5 is switched to the alarm type display as shown in FIGS. Thereby, the guide light 1 can perform not only evacuation guidance for a tsunami as shown in FIG.

  Moreover, the control part 32a specifies the refuge corresponding to the kind of alarm signal with reference to the refuge information memorize | stored in the memory | storage part 32b. And the display apparatus 3A of the direction display part 5 displays the guidance direction to the refuge specified by the control part 32a. An area number is set in the broadcast radio signal described above. Therefore, the storage unit 32b of each guide light 1 stores its own installation position information, and upon receiving a broadcast radio signal, the control unit 32a identifies the shelter information corresponding to the type of disaster. And the direction of guidance to the evacuation site is displayed.

  For example, as shown in FIG. 13, when the warning signal is a tsunami, each guide light 1 is guided to the optimum evacuation place (finger point position in the figure) when evacuating from its own installation position. Display direction automatically. In the storage unit 32b of the guide light 1, an optimum guide direction according to the type of disaster and the installation position of the guide light is set. Note that the optimal evacuation site is not necessarily the nearest evacuation site, and if it is a tsunami, it may be preferable to evacuate in a higher altitude direction. However, at a high altitude, the guidance direction may be set in the same direction as the tsunami traveling direction.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, as long as the guide lamp 1 is suspended from a viaduct, the direction display unit 5 is not limited to a vertical plane, and may be provided below the horizontal plane. In addition, since the side light emission part 6 needs to oppose the road advancing direction, it is provided in the vertical surface orthogonal to the direction display part 5. FIG.
