  In Japan, the operation of a nationwide instantaneous warning system (commonly known as J-ALERT) has been started. As shown in FIG. 2, the J-ALERT transmits information (J-ALERT signal) such as tsunami information, emergency earthquake bulletins, etc. regarding a situation where there is no time for coping, from the Fire Department using satellites. And, by automatically activating the disaster prevention administrative radio (broadcast radio) and the like of the municipality, the emergency information is instantly transmitted from the country to the residents. Here, an earthquake disaster is taken as an example. Seismic waves include P waves (longitudinal waves) that cause small shaking called initial tremor, and S waves (transverse waves) that cause large shaking called main movement. Among them, when a P wave with high propagation speed is detected at a point close to the hypocenter, the propagation of the S wave coming later is predicted time-sequentially from the detection result. We announce forecast before the arrival to point that we left a certain distance from. At 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 guidance lamp 1 of the present embodiment, the emergency alert issuing organization is the municipal office directly mentioned above, and in a broad sense includes the various agencies such as the fire department mentioned above, and the alarm signal is a broadcast radio signal However, in a broad sense, it includes emergency signals and the like other than the above-mentioned J-ALERT signal.

  As shown in FIG. 3, the guide lamp 1 is installed together with a street lamp 7 which illuminates a road or the like mainly at night. The street lamp 7 is connected to the commercial AC power supply AC via an EE switch that automatically turns on the street light when the environment becomes dark and turns off automatically at a predetermined set time, for example. On the other hand, the induction lamp 1 is charged by a commercial AC power supply AC and connected to an uninterruptible power supply battery 8 which supplies the induction lamp 1 at the time of a power failure. In addition to the transmitting / receiving unit 2 and the light source 3, the guiding light 1 controls the control power supply unit 31 that controls a predetermined power supply voltage necessary to light the light source 3. And a lamp control interface (I / F) 32 for outputting a flash start signal.

  The transmitting / receiving unit 2 includes a transmitting / receiving circuit unit 22 (see also FIG. 5) for amplifying a radio wave received by the antenna 21 and analyzing an alarm signal in addition to the antenna 21 described above. If the housing 41 of the lamp main body 4 is made of resin, the transmission / reception unit 2 may be installed in the lamp main body 4. However, from the viewpoint of physical strength and weather resistance, the housing 41 is preferably made of a sturdy metal, and in this case, the transmitting and receiving unit 2 needs to be mounted on the lamp body 4. Therefore, the transmitting / receiving unit 2 of this embodiment is provided on the surface opposite to the surface on which the direction display unit 5 is provided in the lamp main body 4, that is, on the back surface 41a of the housing 41. Particularly preferred from the viewpoint. In addition, by providing the transmitting / receiving unit 2 on the back surface 41 a of the housing 41, it is possible to prevent the direction display unit 5 on the front of the device and the side light emitting unit 6 on both side surfaces 41 d and 41 e from being interfered.

The lamp control interface 32 outputs a flash start signal for lighting the light source 3 with a predetermined lighting pattern based on the information included in the various emergency alarms from the alarm signals 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 the street light 7. The pole 9 is not limited to the one dedicated to the street lamp 7 as illustrated, and may be, for example, a general utility pole or the like. The guide light 1 is provided at a position lower than the street light 7 and in a position where it is easy to stay at the eyes of people. The street lamp 7 includes, for example, a light source unit 71, a main body 72 accommodating the light source unit 71, and a cover 73 for diffusing and emitting light emitted from each LED light source 71a of the light source unit 71.

The housing 41 of the lamp body 4 is formed by pressing and cutting a plate material such as a stainless steel plate or an aluminum plate having a predetermined rigidity into the above-described shape. A white paint having a high visible light reflectance is applied or a reflective metal material is vapor-deposited on the back surface 41a and the inner surface of both side surfaces 41d and 41e. The frame 42 is formed of the same material as the housing 41. A packing member or the like may be disposed between the frame 42 and the opening of the housing 41 to prevent the entry of water into the lamp body 4. In addition, the side light emission part 6 is not limited to the structure shown to FIG.1 and FIG.5, but as shown to Fig.6 (a) thru | or (d), one rectangular side opening 61a, 61b is a side panel 62a. , 62b may be provided. Also, for example, the circular side light emitting unit 6 shown in FIG. 5A is provided on one side surface 41 d, and the rectangular side light emitting unit 6 shown in FIG. 6C is provided on the other side surface 41 e. It may be done.

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

  The light source 3 includes a solid light emitting element (LED) 3a, an optical member 3b provided in the light extraction direction of the LED 3a and distributing the light emitted from the LED 3a at a wide angle, and a base unit 3c holding the LED 3a and the optical member 3b. And. The LED 3a is configured as an LED package by being covered with a wavelength conversion member that converts the wavelength of the emitted light of the LED chip. The LED 3a is not particularly limited as long as it is a light source capable of emitting light of a desired light color as the induction lamp 1, but a GaN-based blue LED chip emitting blue light with an emission peak wavelength of 460 nm is coated with YAG-based phosphors. 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 the electrodes provided on the upper surface of the LED 3a are connected to the lands provided on the mounting surface using wires.

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

  When the guide light 1 of this embodiment receives an alarm signal, each light source 3 is turned on, and the light is emitted into the lamp main body 4 and is emitted from the display panel 52 mainly in front of the light source 3 to the outside of the lamp Ru. Further, since the light source 3 has a wide-angle light distribution by the optical member 3 b described above, light is emitted also in the side direction of the light source 3, and from the side light emitting portions 6 provided on the side surfaces 41 d and 41 e It is also emitted. The side light emitting unit 6 provided on the side surface 41d opposite to the guiding direction is provided with the side panel 62a colored with green, and thus emits green light. Further, the side light emitting unit 6 provided on the side surface 41 e in the guiding direction emits the red light because the side panel 62 b to which the red coloring is applied is provided.

  That is, when the person who is going to evacuate at the time of disaster sees the guide light 1 from the side, and when it is directed in the induction direction, as shown in FIG. Since 6 is visually recognized, it is recognized that it is sufficient to proceed to the same as the traffic light. On the other hand, when the person who is going to evacuate is facing in the opposite direction to the guidance direction, as shown in FIG. I recognize that I can not do it. Thus, according to the guide light 1 of the present embodiment, not only the direction display unit 5 provided on the front face of the guide light 1, but side light emission to the side of the guide light 1 that is easy for the person traveling on the road to see By providing the part 6, the evacuation direction can be effectively viewed by the evacuating person. In addition, as shown in FIG. 4, since both of the direction display unit 5 and the side light emitting unit 6 display and emit the induction direction by the light emitted from the light source 3, the device configuration can be simplified. . In addition, by using an LED light source as the light source 3, the driving time of the uninterruptible power supply battery 8 can be extended, and since the light source replacement cycle is long, it is possible to suppress the labor and cost required for maintenance.

  Further, as described above, the guidance lamp 1 according to the present embodiment causes the person facing in the guidance direction to visually recognize one side light emitting unit 6 that emits green light, and the person facing in the opposite direction to the guidance direction Causes the other side light emitting unit 6 to emit red light. As described above, if the side light emitting portion 6 indicates the induction direction by the light color, even for the side surface 41 d, 41 e having a smaller area than the direction display portion 5 on the front surface of the induction lamp 1, The guidance direction can be recognized.

  As shown in FIG. 7, a plurality of guide lights 1 configured in this manner are provided along the 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 lights in conjunction with the alarm signal transmitted from the emergency alarm issuing agency. At this time, it is visually recognized from the person M in evacuation that the side light emitting unit 6 of the guide lights 1b and 1c in the guiding direction (arrows in the drawing) is lit in green. Even if it is in a position where it is difficult to see, it can be recognized that it is sufficient to proceed in that direction. On the other hand, since it is visually recognized that the side light emitting portion 6 of the induction lamp 1a opposite to the induction direction is lit in red, it can be recognized that it should not proceed in that direction. As described above, in the induction lamp 1 according to the present embodiment, two different types of induction information, which can be advanced or can not be advanced, can be displayed because the emission colors of the side light emitting portions 6 facing each other are different.

  Next, the person M who has advanced to the vicinity of the intersection CR recognizes that the guidance lamp 1d in the straight direction of the intersection CR is lit in red, and therefore recognizes that he should not go straight on the intersection CR. Can. In addition, when it is visually recognized that the side light emitting unit 6 of the guide light 1e on the evacuation site EP side is lit in green, it can be recognized that the direction is the guidance direction. These guide lights 1a to 1e are not controlled by the controller placed in the existing disaster prevention equipment, but are individually turned on in conjunction with the 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 guidance direction correct for the person M who is going to evacuate Can be recognized.

  A guide lamp according to a modification of the above embodiment will be described with reference to FIG. The guide lamp 1 of the present modification further includes a tilt measurement unit 34 that measures the tilt 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 guiding light 1 as shown in FIG. 4 may collapse and be damaged, and the guiding direction displayed by the guiding light 1 is not necessarily 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 erroneous display, there is a possibility that the person to be evacuated may be guided in the wrong direction. Therefore, when the inclination of the lamp body 4 exceeds the predetermined threshold value, the light source 3 is turned off to stop the display itself of the guidance direction by the direction display unit 5 or the side light emitting unit 6, thereby evacuating the person. Can be suppressed in the wrong direction.

  Next, a guide lamp according to a second embodiment of the present invention will be described with reference to FIG. 9 and FIG. As shown in FIG. 9, the induction lamp 1 according to the present embodiment includes a side light source 63 which is an individual light source as the side light emitting section 6, and a side control power supply 64 that supplies power to the side light source 63. And. The light source 3 is used exclusively for the direction display unit 5. The other configuration is the same as the above embodiment.

  Moreover, as the guide lamp 1 of this embodiment is shown to FIG. 10 (a) thru | or (d), the side light emission part 6 is provided only in one side 41 d. 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. Diffusion processing is performed on one outer surface of the display panel 52, and light guided while being totally reflected in the display panel 52 is emitted from the outer surface.

  The side light source 63 has 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 is mainly for making the display on the display panel 52 of the direction display unit 5 float and easy to view, and does not necessarily require light emission by high output. Therefore, the output of the light emitted from the side light emitting unit 6 is not high either, and for example, the visibility of the side light emitting unit 6 from a distance can not be high under conditions where there are a lot of fog and dust.

  On the other hand, according to the induction lamp 1 of the present embodiment, the side light source 6 is provided with the dedicated side light source 63, so that the light output of the side light source 63 can be increased. The visibility of the side light emitting unit 6 can be enhanced. In addition, since the direction display unit 5 needs to display a displayed figure or the like, the side light emitting unit 6 using the dedicated side light source 63 blinks, for example, while the light source 3 is continuously turned on. By performing motion control, it is possible to draw more attention of the evacuee.

  Further, the main purpose of the guide lamp 1 of the present embodiment is to improve the visibility and to enhance the attention of the side light emitting portion 6, and the light emission color is not limited to green or red as in the above embodiment. It may be white, orange or the like. In addition, although the side light emission part 6 is provided only in one side 41 d, you may be provided in the other side 41 e. Moreover, in this embodiment, although the xenon lamp unit 63 is used for the side part light source 63, a LED lamp unit may be used.

  Next, a guide lamp according to a third embodiment of the present invention will be described with reference to FIG. 11 to FIG. As shown in FIG. 11, the guide light 1 of the present embodiment stores a control unit 32 a that determines the type of alarm signal received by the transmitting and receiving unit 2, and shelter information that is set according to the type of alarm signal. And a storage unit 32b. These are realized by a microcomputer and a memory incorporated in the lamp control I / F 32. The other configuration is the same as the above embodiment.

  Further, the guide lamp 1 of the present embodiment includes the display device 5A as the direction display unit 5. The display device 5A is configured as an electric light display panel, and can display an arbitrary character or graphic set in advance in the storage unit 32b. The J-ALERT signal and the broadcast radio signal described above have different numbers included in the signal due to tsunami information, emergency earthquake alert, heavy rain (earth and sand disaster) and the like. Therefore, when the transmitting and receiving unit 2 receives the alarm signal, the control unit 32a identifies the type of disaster included in the alarm signal, and displays the direction display as shown in FIG. 12 (a) according to the type. The display of the unit 5 is switched to the display of the type of alarm as shown in FIGS. 12 (b) to 12 (d). Thereby, the guidance lamp 1 can perform not only evacuation guidance for a tsunami as shown in FIG. 12A but also notification of various types of disasters.

  Further, the control unit 32a refers to the evacuation site information stored in the storage unit 32b, and identifies the evacuation site corresponding to the type of the alarm signal. Then, the display device 3A of the direction display unit 5 displays the guidance direction to the shelter identified by the control unit 32a. An area number is set in the broadcast radio signal described above. Therefore, the storage portion 32b of each guidance light 1 stores its own installation position information, and when it receives a broadcast radio signal, the control portion 32a identifies evacuation site information corresponding to the type of disaster. And display the guidance direction to the evacuation site.

  For example, as shown in FIG. 13, when the warning signal is a tsunami, each guide light 1 guides the user to an evacuation site (finger point position in the figure) which is optimal when evacuating from the installation position of the user. Display the direction automatically. In the storage unit 32b of the guiding light 1, an optimum guiding direction according to the type of disaster and the installation position of the guiding light is set. In addition, the optimal evacuation site is not necessarily the closest evacuation site, and in the case of a tsunami, it may be preferable to evacuate in a higher elevation direction, and as shown in the figure, it is preferable to At high elevations, the guidance direction may be set in the same direction as the tsunami travel direction.

  The present invention is not limited to the above embodiment, and various modifications are possible. For example, as long as the guide light 1 is suspended from the viaduct, the direction display unit 5 may be provided not only on the vertical surface but also on the lower side of the horizontal surface. In addition, since it is necessary to oppose the road advancing direction, the side light emission part 6 is provided in the perpendicular surface orthogonal to the direction display part 5.
