  By the way, it is the fact that one police station has less number of accident-handling vehicles than police cars. And there is also a circumstance that it can not go to the accident processing site if both the accident disposal car and the police car are aligned. In addition, in the case of an accident site on a narrow back road, it is less likely to cause traffic congestion around the accident site if the number of emergency vehicles rushing is small. That is, if the surface emitting display can be mounted on overwhelmingly many police cars, it is possible to promptly cope with many accident sites with only the police cars.

  Therefore, it may be considered to arrange the lightning display board 51 for the interior of the accident disposal vehicle Q described above at the rear of the police car. However, the police car is supposed to have a good view during normal operation, not only for the front window but also for both side windows and rear windows. Under such circumstances, at present, it has been impossible to mount a bulky surface light emitting display as described above on a police car.

  On the other hand, let us consider that the surface light emitting display is configured separately from the emergency vehicle, and the surface light emitting display is transported and used at an installation site. However, when the wind blows at the installation site such as a wide road, the rigid and single-piece supporting substrate can not but receive the wind properly. Therefore, there is a possibility that the installed surface light emitting display may be knocked down or blown off by the wind.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a surface light emitting display which can be compactly rolled and carried and which can be mounted on a vehicle or the like.

  In order to achieve the above object, in the surface light emitting display device according to the present invention, a plurality of LED light emitting elements are installed on a long strip-like substrate at predetermined intervals in the strip longitudinal direction to form a light emitting module; Are arranged parallel to one another to form a surface emitting unit, and the surface emitting unit is attached to a sheet, wherein the light emitting module and the sheet are made of a flexible material that can be wound up. It is characterized by

  Further, in the above-mentioned configuration, the seat body is characterized by including a locking member which is detachably locked to the emergency vehicle or the installation stand. Examples of the emergency vehicles include police vehicles such as police cars and accident disposal vehicles, SDF vehicles, local government group disaster prevention vehicles, ambulances, gas leak disposal vehicles, construction vehicles and the like.

  And in each above-mentioned composition, a plurality of vents are formed and a sheet body is characterized by ventilation being constituted.

  Furthermore, in each of the above-described configurations, the sheet body is characterized by being formed of a flexible synthetic resin lattice-like body.

  According to the surface emitting display according to the present invention, since the light emitting module and the sheet are made of a flexible material which can be wound up, the whole surface emitting display can be compactly wound when not in use. it can. The rolled-up product can be easily carried and stored on the vehicle trunk or in-vehicle rear board. On the other hand, in use, the surface light emitting unit and the sheet can be spread flat easily, and a warning character image or the like can be displayed on the surface light emitting unit.

  Further, in the case where the locking member is provided, the surface light emitting display can be locked by being held by the emergency vehicle or the installation stand via the locking member. Therefore, a warning character image or the like can be displayed at the installation site using the emergency vehicle or the installation stand.

  And, in the case where the sheet body has a plurality of vents that can be ventilated, when the surface light emitting display is installed outdoors for image display, the sheet is ventilated even if some wind is blowing. You can let the wind escape through your mouth. Thus, it is possible to prevent the surface emitting display from being overturned or blown away by the wind.

  Furthermore, in the case where the sheet is made of a flexible synthetic resin lattice-like member, it becomes easier to round more and the holding grid hole also serves as a ventilation hole and is used as a mounting hole for the locking member It will also be possible.

Hereinafter, embodiments of the present invention will be described based on the drawings. The embodiments described below are merely examples embodying the present invention, and do not limit the technical scope of the present invention. Here, FIG. 1 is a front view of a surface emission display according to an embodiment of the present invention, FIG. 2 is a view showing the surface emission display, (a) is a partially enlarged front view, (b) is It is an AA line arrow directional cross-sectional view in (a).
In each of the drawings, the surface light emitting display 1 according to this embodiment includes a sheet 2 formed of a grid 2A in a rectangular shape in a front view, a surface light emitter 3 attached to the sheet 2, and a surface light emitter 3 comprising fixing members 7 and 8 for attaching the seat 2 to the seat 2, and a magnet plate 29 (example of a locking member) attached to the seat 2 for holding the display in the emergency vehicle ing.

  The sheet 2 is made of a flexible synthetic resin (for example, soft polypropylene) which can be bent and deformed in any of the longitudinal direction (n direction) and the lateral direction (m direction). Further, the sheet 2 is formed as a lattice-like body 2A having crosspieces 2D extending in the longitudinal and lateral directions. A large number of grid holes 9, 9, 9,... Are formed between the vertical and horizontal crosspieces 2D, and each grid hole 9 doubles as a vent 10 capable of ventilation. The lattice holes 9 near the upper side 2B of the sheet 2 also serve as locking holes into which the mounting protrusions 29A of the magnet plate 29 are inserted and locked.

  The surface light emitting unit 3 includes a large number (30 sheets in this example) of light emitting modules 30, 30, 30,... Arranged in parallel to each other. In each of the light emitting modules 30, a large number (45 in this example) of LED light emitting portions 11, 11, 11,... The modules are mounted relatively apart, and commercially available modules may be used. The belt-like substrate 6 is mainly made of a flexible synthetic resin (for example, soft polyester) which can be taken up in the longitudinal direction of the belt, and the belt width is 10 mm, for example. Then, the respective belt-like substrates 6 are fixed to the crosspieces 2D of the sheet 2 by the fixing members 8, 8, 8 and 8 such as binding bands, whereby the light emitting modules 30, 30, 30, ... are parallel to each other. Fixedly placed. The left and right end portions of the light emitting modules 30, 30, 30,... Are disposed on the surfaces of the flat plates 4 as rigid bodies, and the back sides of the flat plates 4 are positioned near the left and right sides of the sheet 2. It is installed and fixed to the crosspiece 2D of the sheet 2 by fixing members 7, 7, 7 and 7 such as a binding band. Each of the LED light emitting units 11 adjusts the light intensity of each of red light, green light and blue light to output a color tone of millions of colors, a connector 13 for connecting a power line and a signal line, and a capacitor 14 and so on. The connector 13 is composed of a capacitor connection portion 15, a ground connection portion 16 and a power line connection portion 17.

  Then, on the back surface of the sheet 2 on the side of one flat plate 4, a control unit 18 that performs power supply and light emission control to the surface light emitting unit 3 is disposed. Here, a schematic configuration of the electric system of the surface light emitting unit 3 is shown in FIG. The power (AC 100 V) from the plug 20 connected to the power outlet is converted to DC 12 V by the power adapter 19 having the voltage regulator 23 and the like. The power of 12 V DC is supplied to the control unit 18 wired by the connectors 21 and 22. In the control unit 18, the controller 25 together with the crystal oscillator 24, the integrated circuit 26 and the like calculate the supplied power and the dimming signal to be output to the LED light emitting units 11, 11, 11, 11. It outputs to each through connectors 27 and 28. The control unit 18 has a CPU, a memory, and the like (not shown), and character image data for emitting and displaying the display image T, color tone data of each character, scroll data, and the like are preset and stored in the memory. There is.

The operation of the surface light emitting display 1 configured as described above will now be described.
First, when not used, as shown in FIG. 4, the strip-like substrate 6 and the sheet 2 of the surface light emitting unit 3 are integrally wound, for example, from one flat plate 4 side to the other flat plate 4 side. Then, after the clasping belt 31 is wound around the winding body on which the entire surface emitting display 1 is wound, the surface fasteners 32, 33 at both ends of the clinching belt 31 are engaged and held. As described above, when the surface-emitting display 1 is wound, the winding diameter d of the winding body is about 160 mmφ (usually about 250 mmφ) at the minimum, and can be stored in an extremely compact form. By the way, the surface light emitting display 1 is about 5 mm in length and about 5 mm in thickness in the longitudinal direction (arrow m direction) in the unfolded state, and its weight is about 1 kg including the power supply adapter 19 and the like. It is relatively lightweight. The weight and size of the surface light emitting display 1 are not limited as long as they can be transported by the trunk of a car or the like. For example, the winding diameter d of the winding body is 400 mm or less and the weight 5 kg or less , Practically preferable.

  The surface emitting display 1 wound as described above is lightweight and can be carried compactly. And as shown in FIG. 5, in the police car P which is an emergency vehicle, the trunk panel 41 can be accommodated in the open trunk 40 unreasonably. That is, when not in use, the view of the side window and the rear window is not blocked. In this case, the mounting projections 29A of the magnet plates 29, 29 are inserted in advance in the lattice holes 9, 9 near the upper side 2B of the sheet 2 of the surface light emitting display 1, and the magnet plates 29, 29 are fixed. ing.

  On the other hand, when the surface light emitting display 1 is carried into the accident treatment site and used, the trunk panel 41 is opened and the surface light emitting display 1 is taken out from the trunk 40 and further the fastening belt 31 from the surface light emitting display 1 Are removed, and the band-like substrate 6 and the sheet 2 are spread flat. Then, the magnet plates 29, 29 as locking members can be magnetically attached and locked to the inner surface of the trunk panel 41 in the upright state. Thereby, as shown in FIG. 6, the surface emitting display 1 can be suspended at a relatively high position. In this example, the lower side 2C of the sheet body 2 is left as it is. Subsequently, the connector 22 from the control unit 18 is connected to the connector 34 connected to the cigarette lighter power supply (DC 12 V) of the police car P, and the power to the control unit 18 is supplied. Then, when the on switch is turned on, the control unit 18 turns on / off the LED light emitting elements 12, 12, 12, ... at a predetermined position of the surface light emitting unit 3, for example, "during accident processing" The display image T representing the warning character is lighted, and scroll movement is performed in the arrow F direction. Incidentally, in this surface light emitting display 1, even if power is supplied to the control unit 18 by connecting eight AA batteries in series instead of the cigarette lighter power supply, scroll display of the display image T for 3 hours is possible. The

  After the surface light emitting display 1 is taken out of the trunk 40 and expanded, the trunk panel 41 is closed, and as shown in FIG. 7, the magnet plates 29, 29 are magnetically attached to the outer surface of the trunk panel 41 and locked. It is also possible to use it. Such a mode of use is suitable for the case where the display position of the display image T is lowered but it is not desirable to make it as in the case of display such as "during inspection".

  Furthermore, as shown in FIG. 8, an installation stand S is separately prepared and arranged on the side of the police car P, and hooks (examples of locking members) 36 and 36 are provided on the horizontal bar 35 of the installation stand S. , 36, 36, and the hooks 36, 36, 36, 36 may be engaged with the upper side 2B of the sheet 2 to suspend the surface light emitting display 1. Also in this case, the display image T may be illuminated and displayed upon receiving power supply from the cigarette lighter power source of the police car P or the dry cell.

  As described above, the surface light emitting display 1 according to this embodiment is a simple display, and when not in use, the surface light emitting display 1 can be wound compactly and can be transported to the installation site. The sheet 2 can be expanded flat, and a warning character image or the like can be displayed on the surface light emitting unit 3.

Further, since the sheet 2 has a large number of vents 10 and there is a gap between the upper and lower light emitting modules 30, 30, a slight wind blows when the surface light emitting display 1 is installed outdoors. Even in this case, the wind can be released through the vent 10 or a gap. Thus, the surface light emitting display 1 can be prevented from being knocked down or blown off.
Furthermore, since the sheet 2 is made of a flexible synthetic resin grid body 2A, it is easy to round and the grid holes 9 also serve as the ventilation holes 10. The grid holes 9 can also be used as mounting holes for the locking members 29 and 36.

  In the above embodiment, the surface light emitting display 1 is disposed and used outside the police car P. However, the present invention is not limited thereto. For example, as shown in FIG. 9, it is possible to attach a hook 37 near the upper side of the rear window 42 inside the police car P and store the rounded surface light emitting display 1 on the rear board 43 at the rear end. is there. Then, in use, the surface light emitting display 1 is unfolded, and the grid holes 9 on the upper side 2B of the sheet 2 are locked to the hooks 37 and held. In this state, when the control unit 18 is operated, it is possible to cause the surface light emitting unit 3 to emit light and display the display image T. That is, during normal operation (when not in use), the wound surface light emitting display 1 does not block the view of the rear window 42, and during use, the surface light emitting display 1 is rapidly expanded to display warning characters and the like in the car It can be done.

  Further, although an example in which the magnet plate 29 and the hook 37 are used as the locking member has been described above, it is also possible to use a suction cup, a surface fastener or the like as the locking member instead of them.

  The present invention is not limited to the above-described embodiment, and includes various modifications, numerical corrections, material changes, etc. which can be conceived by those who have ordinary knowledge in the field of the present invention. Of course, even if there are design changes within the scope of the present invention, they are included in the present invention.
