  The present invention has been made in view of the above circumstances, and an object thereof is to provide a light-emitting display sheet that can be used in such a manner that it is hooked on a window frame or loading platform of a vehicle or the like to send a security instruction, or is folded and stored when not in use. And Another object of the present invention is to provide a light-emitting display sheet that can emit light even with high visibility and a large number of strokes.

The light-emitting display sheet of the first invention uses a plurality of light emitters in which a plurality of light-emitting elements are arranged on a linear substrate at equal intervals, and the light emitters are arranged in parallel at equal intervals to provide a flexible sheet. It is characterized by being attached to.
The light-emitting display sheet according to a second aspect of the present invention is the light-emitting display sheet according to the first aspect, wherein the light-emitting element includes one LED element and a cap that encloses and fixes the LED element, and the cap is formed on the sheet. The sheet is fixed to the sheet while being inserted into the hole.
The light-emitting display sheet according to a third aspect is the light-emitting display sheet according to the second aspect, wherein the cap includes a cylindrical body, a light transmission part that covers the top surface of the body, and a collar part formed on the outer periphery of the light transmission part The synthetic resin is inserted between the sheet and the outer periphery of the body part in a state where the body part is inserted into the hole of the sheet and the back surface of the flange part is in contact with the sheet surface of the outer periphery of the hole. It is characterized by being packed and hardened.

According to the first aspect, since the light emitting elements are arranged in a matrix by arranging the light emitters having the light emitting elements arranged at equal intervals, a warning can be obtained by lighting any light emitting element. A signal can be emitted. Moreover, since the seat is flexible, it can be used by being hooked on a window frame or a loading platform of a vehicle or the like, and can be folded and stored when not in use.
According to the second invention, since the cap constituting the light emitting element is directly fixed to the sheet, the interval between the adjacent light emitting elements can be narrowed. For this reason, since the line which comprises the character light-emitted by the light emitting element becomes dense, visibility is improved and even a character with a large number of strokes can emit light.
According to the third invention, each light emitting element is fixed to the sheet with the synthetic resin filling the sheet from the back and the back side, so the fixing to the sheet is strong and also prevents water from entering the light emitting element. Because it can, it is highly durable.

It is a front view of the light emission display sheet A which concerns on one Embodiment of this invention. (A) is a partial expanded fracture surface of the light emission display sheet A of FIG. 1, (B) is sectional drawing of a fracture | rupture part. (A) is a partial top view of a light-emitting body, (B) is a partial perspective view of a light-emitting body. It is sectional drawing which shows the example of attachment to the sheet | seat of a light-emitting body. It is sectional drawing which shows the other example of attachment of a light-emitting body. It is use condition explanatory drawing of the light emission display sheet A of this invention.

Next, an embodiment of the present invention will be described with reference to the drawings.
A light emitting display sheet A according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
In the light emitting display sheet A, the light emitting elements 10 are arranged on a top sheet 1 in a matrix of a plurality of stages and a plurality of columns. Reference numeral 5 denotes a back surface sheet, and the outer peripheral edge thereof together with the front surface sheet 1 are joined together by an appropriate number of grommets 4 to form the display sheet A in a bag shape.
The sheet 1 and the sheet 5 may be the same material or different materials, but are preferably made of a material that can withstand wind and rain, sunlight, and the like. A hole through which a rope or the like is passed is formed in the periphery of the sheet 1 and the sheet 5 and is reinforced with a grommet 4. If the rope is passed through the grommet 4, the light-emitting display sheet A can be attached to the window frame or loading platform of the vehicle.

Since the light-emitting display sheet A of the present invention is used by being hooked on a window frame or the like of a security vehicle as shown in FIG. 6, the sheets 1 and 5 are required to have flexibility.
For this reason, a flexible material is used for the sheets 1 and 5, for example, a canvas or a chemical fiber sheet is preferable.
When such a flexible sheet is used, it can be easily folded and stored when not in use, and a curved portion can be hooked along the same.

  The most preferable dimensions of the light-emitting display sheet A are about 40 cm in length and about 240 cm in width, but this is a dimension determined for the convenience of handling and is not limited thereto. For convenience of handling, it may be about 30-60 cm in length and about 200-480 cm in width. Furthermore, if you want to increase the amount of characters to be displayed, you can make it larger than these dimensions, and if you want to use fewer characters, It may be small.

  In the illustrated light-emitting display sheet A, the number of light-emitting elements 10 that can display various characters is arranged in a matrix. And, 4 or 8 sets of light emitting elements 10 each having 16 to 24 vertical x 64 to 192 horizontal, preferably 16 vertical to 16 horizontal are arranged so as to display approximately four characters. By selecting the light-emitting body 2 to be lit, for example, a character indicating a warning or an instruction such as “no traffic” is lit.

Next, details of the light emitter 2 will be described.
As shown in FIG. 2, the light emitter 2 is obtained by attaching a plurality of light emitting elements 10 to a linear substrate 20 at equal intervals. A plurality of light emitters 2 are arranged in parallel and attached to the top sheet 1.

As shown in FIGS. 2 and 3, each light emitter 2 has light emitting elements 10 attached to a substrate 20 in a straight line at equal intervals. Although only two light emitting elements 10 are shown in FIG. 3, in reality, 16 are attached as shown in FIG. In addition, 16 light emitters 2 are attached in a space for one character.
The light emitting element 10 shown in FIG. 3 is the same as that shown in FIG. 4, and the LED element 11 is fixed to the LED substrate 12, and four pins 13 protrude from the LED substrate 12 for each element 11. .

A method of attaching the light emitter 2 to the sheet 1 will be described with reference to FIGS. 4 and 5.
In the example of FIG. 4, 1 h is a hole formed in the top sheet 1. As described above, in the light emitting element 10, the LED element 11 is fixed on the surface of the LED substrate 12, and is fixed on the substrate 20 via the pins 13. The cap 14 includes a cylindrical body portion 15 and a light transmission portion 16 formed on the top surface thereof, and a flange portion 17 is formed on the outer periphery of the light transmission portion 16.

  The body portion 15 of the cap 14 is inserted into the hole 1h of the surface sheet 1, and the flange 17 is in contact with the surface sheet 1 outside the hole 1h. On the back surface of the top sheet 1, a fixing ring 18 is fitted into the body portion 15, and the top sheet 1 is sandwiched between the fixing ring 18 and the flange 17. In this state, the synthetic resin 19 is filled and hardened around the fixing ring 18 and between the back surface of the topsheet 1 and the body portion 1S.

  With such a fixing structure, each light emitting element 10 is fixed to the top sheet 1, and the light emitter 2 is also fixed to the top sheet 12. Further, since the liquid tightness is ensured by the synthetic resin 19, the light emitting element 10 can be waterproofed.

  The attachment example of FIG. 5 is not substantially different from the attachment example of FIG. The light emitting element 10 is different only in that the LED element 11 is directly fixed to the substrate 20.

  According to the above embodiment, the light emitting elements 10 are arranged in a matrix by arranging the light emitters 2 in which the light emitting elements 10 are arranged at equal intervals. For this reason, a warning signal can be emitted by lighting any light emitting element 10. Moreover, since the cap 14 which comprises the light emitting element 10 is being directly fixed to the sheet | seat 1, the space | interval between adjacent light emitting elements 10 can be narrowed. For this reason, since the line which comprises the character light-emitted with the light emitting element 10 becomes precise | minute, the visibility from a distant place becomes high, and it can light-emit also on a character with many strokes, for example, a Chinese character.

The diameter D of the light emitting element 10 shown in FIG. 4 is 12 mm, and the distance d between adjacent light emitting elements 10 is 18 mm (the distance between contours is 6 mm), which is an optimum value, but is not limited thereto. As a preferable range, the diameter D of the light emitting element 10 can be 10 mm to 40 mm, and the distance d between the adjacent light emitting elements 10 can be very narrow 13 to 25 mm. Furthermore, it can be used if it can be used for sending a warning even outside these ranges.
With the dimensions and spacing of the above optimum values, 16 × 16 light emitting elements 10 can be arranged in a frame of a little less than 30 cm, characters can be displayed, and visibility is improved even from a distance or at night. .

  An appropriate controller may be connected to the light emitting display sheet A of the present invention to select any light emitting element 10 to emit light. By this controller, the light emitter 2 can be turned on, turned off, blinked, etc. by selecting from among the many light emitters 2 to generate a warning light signal. The controller can also be operated by remote control, which eliminates the need for an operator to leave a hazardous location.

Next, how to use the light emitting display sheet A of the present invention will be described.
As shown in FIG. 6, the light emitting display sheet A can be attached to a window frame or the like (an arbitrary member such as a loading platform) of the vehicle C with a rope or hooked with an appropriate hook. Even if the mounting location is curved, the light-emitting display sheet A is flexible and can be mounted.
The illustrated light-emitting display sheet A can display four characters, but if two or more light-emitting display sheets A are used in series, eight or twelve characters can be displayed.

Although FIG. 6 shows a state where the characters “passage prohibited” are displayed on the light-emitting display sheet A in a light-emitting manner, there are no restrictions on the types and number of characters to be displayed.
As a typical example, various warnings such as various stop commands and leaving commands necessary for security can be issued.
