  The present invention will be described in detail based on the embodiments shown in the drawings.

  FIG. 1 is a perspective view of a surface light emitting display 1 according to a first embodiment, FIG. 2 is a plan view, and FIG. 3 is an explanatory side view. A surface-emitting display 1 that is a self-powered type includes a planar plane portion 2 that is placed directly on an existing platform, a path, and the like, and a cylindrical shape that extends downward from one end of the plane portion 2. It is composed of an embedded portion 3, a light emitting portion 4 that is fixed above the recessed portion of the flat portion 2, and a storage device portion 5 that is connected to the light emitting portion 4 and accommodated in the embedded portion 3. Yes.

  The flat surface portion 2 has a rectangular shape when viewed from above, and the periphery is provided with slope-shaped inclined portions 2a and 2b with a gentle inclination. The size of the flat portion 2 is, for example, 1 m wide, 15 cm long, and about 1 cm in height at the top, and the horizontal and vertical lengths are appropriately selected according to the size of the existing tiles and the like. It is possible.

  The flat surface portion 2 includes an inclined portion 2a along both long sides, an inclined portion 2b along both short sides, and a concave portion 2c surrounded by these inclined portions 2a and 2b. The inclined portions 2a and 2b and the concave portion 2c are made of a strong metal material, for example, a stainless steel plate having a thickness of 5 mm, an aluminum plate or the like. Although not shown in the inclined portions 2a and 2b, they will be described later at appropriate intervals. A through hole for fixing to the floor plate F of the platform to be formed is drilled.

  FIG. 4 is a cross-sectional view taken along the line AA ′ of the plan view of FIG. 2, and a white sheet layer 2d made of white or colored white sheet material and a light reflecting layer 2e are arranged in the recess 2c from the bottom side. Further, the light guide plate portion 2f is laminated immediately above the light reflecting layer 2e. Only the white sheet layer 2d is provided on the inner surface of the recess 2c, and the white sheet layer 2d may be a mirror-like sheet body that reflects a lot of light.

  The light reflecting layer 2e is made of a synthetic resin sheet such as polycarbonate or acrylic. The surface of the light reflecting layer 2e is formed with a number of angled groove shapes, and the light reflectance increases as the distance from the light emitting portion 4 increases. That is, in the vicinity of the light emitting portion 4, the groove pitch is wide, for example, about 0.3 mm, and the angle of the mountain is gently formed. At a position away from the light emitting portion 4, the groove pitch is narrow, for example, about 0.1 mm. The angle of the mountain is sharp.

  The light guide plate portion 2f is made of a transparent synthetic resin such as polycarbonate or acrylic and is fitted in the recess 2c. The surface of the light guide plate portion 2f is continuous with the top portions of the inclined portions 2a and 2b without a step. The light guide plate portion 2f is a transparent flat body, and any material other than polycarbonate can be adopted as long as it has strength against pressing force from above.

  In addition, the thickness of the light guide plate portion 2f is substantially equal to the height of the side surface of the recess 2c. For this reason, the light guide plate portion 2f has a structure that is not easily damaged by the pressing force from above. In the case of manufacturing, a light guide plate portion 2f made of a plate material such as polycarbonate in consideration of the convex shape of the light emitting portion 4 may be prepared in advance, and fitted into the concave portion 2c to be fixed. Alternatively, in a state where the white sheet layer 2d and the light reflection layer 2e are laminated in the recess 2c, the melted polycarbonate can be filled in the recess 2c.

  The buried portion 3 is connected to the bottom surface of one end portion of the recess 2c with its central axis directed in the vertical direction. The buried portion 3 has, for example, a cylindrical shape having a diameter of 10 cm, a height of 10 cm, and a thickness of about 3 mm, and has a bottom portion 3a that can be removed and opened at the bottom. A metal such as stainless steel or a synthetic resin having corrosion resistance other than the metal can be used as the material of the embedded portion 3.

  On one side of the recess 2c to which the embedded portion 3 is connected, a rectangular hole 2g whose length substantially coincides with the short side of the recess 2c is provided along the short side of the recess 2c. At the upper end of the embedded portion 3, the light emitting portion 4 is fixed to the concave portion 2 c with the hole 2 g being inserted and a part protruding upward from the concave portion 2 c.

  The light emitting part 4 is fixed to the recess 2c by screwing or the like so as to close the hole 2g, and the surface of the light emitting part 4 protruding through the hole 2g emits light on the other end side of the recess 2c. A light emitting body 4a is provided. The light emitting main body 4a has a plurality of LED elements arranged in a line along the short side of the recess 2c, and emits light in a substantially horizontal direction.

  For example, a red high-luminance LED element suitable for alerting is preferably used for the line-shaped light-emitting main body 4a. In addition to the red high-intensity LED element, blue and green high-intensity LED elements can also be arranged together with the red high-intensity LED element.

  Alternatively, the embedded portion 3 and the light emitting portion 4 may be disposed at the center of the recess 2 c, and the light emitting main body portions 4 a that emit light in a substantially horizontal direction may be disposed on both surfaces of the light emitting portion 4. By arranging in this way, the distance to the far end is shortened, so that the surface emission can be made brighter than when the same high-intensity LED element is used.

  A storage device unit 5 is arranged below the light emitting unit 4 and in the embedded unit 3 as shown in FIG. 3, and the storage device unit 5 is connected to the long-life battery 5a and the long-life battery 5a. And a clock unit 5b.

  In FIG. 3, the long-life battery 5 a and the clock unit 5 b are illustrated by a block diagram. However, the battery 5 a and the clock unit 5 b are fixed in the cylinder of the embedded unit 3 so as to be replaceable by screwing or the like. Regarding the size, the embedded portion 3 is occupied with an appropriate size according to the capacity of the long-life battery 5a.

  As shown in FIG. 3, the storage device unit 5 and the light emitting unit 4, which are easily damaged, are protected by the embedded unit 3. In the storage device unit 5, the long-life battery 5a is an essential component, but the clock unit 5b may not be provided.

  The long-life battery 5a is a small storage battery such as lead or alkali and has a capacity of about several hundred Ah. Even when operations such as blinking control by the clock unit 5b and nighttime light emission control using an illuminance sensor, which will be described later, are performed, it is possible to operate without battery replacement for several years.

  The clock unit 5b has a function of performing lighting timing control of delay lighting. Furthermore, a time zone for lighting may be set, and a function for controlling on / off of lighting control may be added in accordance with the time zone.

  When the surface light emitting display 1 is installed on the platform, first, a circular hole having a diameter slightly larger than the diameter of the embedded portion 3 is formed in the floor plate F of the existing platform at a location several tens of centimeters away from the longitudinal edge of the platform. Is drilled using a drill or the like.

  Then, the surface emitting display 1 is placed on the floor plate F so that the edge portion in the longitudinal direction of the platform and the plane portion 2 are parallel to each other while the embedded portion 3 is inserted into the circular hole.

  Finally, after the final alignment on the floor board F of the surface light emitting display 1, anchor bolts are inserted into the through holes provided in the inclined portions 2 a and 2 b, so that the surface light emitting display 1 is connected to the floor board F. The installation work is completed. By repeating such installation work, the surface emitting display 1 is installed at a predetermined interval over the entire length in the longitudinal direction of the platform. Then, immediately after the surface light emitting display 1 is installed, the blinking control of the light emitting main body 4a is started.

  As described above, according to the surface emitting display 1 of the first embodiment, the work time of the new construction of the thread line is changed for each conventional tile, or the thread line in which a long groove is provided in the existing tile along the thread line. Compared to the construction method, it can be greatly shortened.

  In addition, since power is supplied to the light emitting unit 4 by the long-life battery 5a, there is no need to install a power supply system under the platform or the like, and tiles are not replaced unnecessarily. It is possible.

  FIG. 5 is an explanatory view for explaining the surface light emission of the surface light emitting display 1. The surface light emitting display 1 emits light vertically to the installation surface of the platform, the passage and the like. The substantially horizontal light L emitted from the light emitting main body 4a has a higher light reflectivity as the distance from the light emitting part 4 increases. Therefore, the emitted light L travels through the light guide plate 2f in a substantially horizontal direction. It proceeds while repeating the reflection, and when it enters the angled slope of the light reflection layer 2e, it reflects upward and exits upward from the light guide plate portion 2f. A part of the light L incident on the slope of the angled groove shape of the light reflecting layer 2e is transmitted through the light reflecting layer 2e and reflected by the white sheet layer 2d below the light reflecting layer 2e.

  As shown in FIG. 6, a thread line composed of a plurality of surface-emitting displays 1 is arranged on the floor board F of the platform, and the plurality of surface-emitting displays 1 constituting the thread line blink in synchronization. Moreover, it is also possible to blink while shifting with respect to the adjacent surface emitting display 1. It is also possible to control the blinking in order so that the light from the light emitting unit 4 that is turned on by blinking while shifting moves in the direction in which the train T enters.

  In the delay lighting control that blinks while shifting, the surface emitting displays 11 to 14 shown in FIG. 6 have a synchronized clock unit 5b, and the surface emitting display 11 has a light emitting timing of 0 second by the clock unit 5b. In the surface emitting display 12, the clock unit 5b has a light emission timing of 0.25 seconds, in the surface light emitting display 13, the clock unit 5b has a light emission timing of 0.5 seconds, and in the surface light emitting display 14, the clock unit 5b has a light emission timing of 0. Lights for about 200 ms at 75 seconds emission timing.

  By repeating this at a predetermined period, for example, at a period of 1 second, it is possible to turn on the light so that the light from the light emitting units 4 of the surface light emitting displays 11 to 14 sequentially moves. In addition, it can also be made to light so that light may move over the full length of the longitudinal direction of the platform P by installing the group of the surface emitting display 11-14 adjacently.

  The light reflecting layer 2e does not reflect the strong light L1 in the vicinity of the light emitting main body 4a so much, but the light L2 weakened away from the light emitting main body 4a has a large reflection. Therefore, the surface light emitting display 1 emits uniform surface light as a whole.

  In the sled line in which the surface light emitting display 1 is installed, since surface light emission is sequentially performed as compared with the conventional sled line that performs point light emission at a predetermined interval, a higher alerting effect can be obtained.

  In the first embodiment, the surface-emitting display device 1 is described as being installed on the platform as an example. However, it can be used as a light-emitting device for alerting at an appropriate place such as a road.

  FIG. 7 is a plan view of the surface emitting display according to the second embodiment, and FIG. 8 is a side view illustrating the surface emitting display according to the second embodiment. The surface-emitting display 1 of the first embodiment is used as a thread line for alerting the platform, but the surface-emitting display 1 'of the second embodiment is used as an emergency evacuation guidance display such as a subway or a building. It is installed on the passage or on the wall surface of the passage.

  When the surface-emitting display 1 ′ is used as the guidance display, red, blue, and green high-intensity LED elements are arranged in the light-emitting main body 4a and lighted at the same time so as to emit white light. To.

  Further, a green arrow mark 2h and an emergency exit mark 2i are provided on the surface of the light guide plate portion 2f. By emitting white light from behind these marks, the colored marks can be recognized even from a distance, and can be easily directed toward the emergency exit.

  Moreover, it replaces with the clock part 5b of the storage apparatus part 5 of Example 1, and the illumination intensity sensor 5c is arrange | positioned. The illuminance sensor 5c is installed in the vicinity of the light emitting unit 4 and is irradiated with external light from above, and controls on / off of the light emitting body 4a according to the illuminance from the illuminance sensor 5c. Surface light emission can be performed automatically when lighting or the like falls due to a disaster or when the lighting is turned off at night.

  Note that the illuminance sensor 5c can be incorporated in the storage device unit 5 of the surface light emitting display 1 placed on the platform. In such a case, the intensity of light emitted from the light emitting main body 4a may be adjusted according to the illuminance from the illuminance sensor 5c.

  The surface emitting display 1 ′ is constructed in the same manner as in the surface emitting display 1 of Example 1, by drilling a circular hole on the floor or wall surface using a drill or the like, and inserting the embedded portion 3 into the circular hole. Secure with bolts. Similarly to the surface light emitting display 1 of the first embodiment, the surface light emitting display 1 ′ of the second embodiment can be installed at any place without preparing a power supply facility.

  In addition, a wireless communication unit that receives a lighting control signal or the like from the wireless central device as the storage device unit 5 is provided in the surface emitting displays 1 and 1 'of the first and second embodiments, and performs blinking and lighting control from the wireless central device. You may do it. For example, when a train interlocking device is connected to the wireless central device and a train approach signal is transmitted to the wireless communication unit, the surface emitting display 1 is controlled to blink for a predetermined time, or when a disaster occurs, the surface emitting light is emitted from the wireless central device. You may make it perform lighting control to display 1 '.

  Furthermore, it is possible to cause the light-emitting main body 4a of the surface light emitting display 1 to emit light in an arbitrary color based on a light emission color command from the wireless central device.

  When cracks or the like occur in the light guide plate part 2f of the surface light emitting display 1, 1 'or the inclined parts 2a, 2b are damaged, the bolts fixing the surface light emitting display 1, 1' are removed, After removing the surface emitting display 1, 1 ', the new surface emitting display 1, 1' can be easily restored from the failure state by installing it by the above construction method.

  Further, in the case where a problem occurs that the light emitting main body 4a of the light emitting unit 4 of the surface light emitting display 1, 1 'does not light up, other than the restoration by replacement of the surface light emitting display 1, 1' as described above. In addition, after the surface emitting display 1 is removed, the bottom portion 3a of the embedded portion 3 is removed, and the components such as the light emitting portion 4 and the long-life battery 5a are removed and replaced by new components. Good.

  Further, light in the substantially horizontal direction from the light emitting portion 4 of the surface light emitting display 1, 1 ′ is irradiated into the light guide plate portion 2f and emitted from the upper light guide plate portion 2f by the white sheet layer 2d and the light reflecting layer 2e. Since the surface light is emitted, the thickness of the flat portion 2 can be reduced.

  Further, since the surface emitting displays 1, 1 'are strong against the pressing force from above, even if many users step on at the same time, they will not be damaged. Furthermore, the surface light emitting displays 1, 1 'have a flat shape and the periphery has a slope shape, so there is no possibility that the user will trip.
