[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a display device formed by linearly connecting LEDs.

[0002]

[Prior art]

 Neon tubes, fluorescent display tubes, and the like are widely used as display devices that perform advertisements and display, and emit light by themselves. However, once these display forms are determined, they cannot be changed. Further, as the above display device, a display device used for Christmas decoration or the like is known. In this device, a small light bulb is directly mechanically connected only by wiring, and by bending the wiring, the position of the light bulb can be changed and the display form can be arbitrarily changed. However, the light bulb is mechanically supported by the wiring, and when the position of the light bulb is changed in order to change the display form many times, there is a problem that the wiring is internally broken and the display cannot be performed.

In addition, a flexible display device of this type is desired to be attached to a support plate such as a glass plate in order to maintain a certain display form, but in this device, a light bulb is exposed naked. However, unless special treatment such as embedding it in the support plate is made, it cannot be attached, and its use is limited. Another problem is that the size of the light bulb determines the size of the points that make up the display form, making it impossible to perform detailed display. For this reason, the applicant has previously provided a plurality of transparent or translucent cases with a built-in LED, and connected the plurality of cases linearly and elastically by a connecting rod having elasticity. , And proposed a display device in which the respective LEDs are connected by a wire having play (utility model registration number 3012073). However, in this device, the LEDs are connected by wires, and the wires are made by bundling thin wires made of a conductor. Therefore, although the wires are mechanically protected by the connecting rod, after all the LED The cross-sections are points, but they must be connected by thin wires, and there is a possibility that disconnection cannot be completely prevented. Therefore, in this product, the wiring is provided with play to prevent the wiring from being deformed as much as possible. However, in this case, not only is the wiring protruding outside the connecting rod and the appearance is not good, but because the wiring coating is thin, it is easily damaged by external force, and because the wiring protrudes from the connecting rod to the outside, there is There was a problem that it was difficult to install the cable because it interfered with the wiring.

[0004]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide a display device capable of reliably preventing disconnection, easy to install, and good in appearance.

[0005]

[Means for Solving the Problems]

 The display device of the present invention is provided with a plurality of cases each having a built-in LED, and the plurality of cases are linearly connected by a connecting rod having elasticity so as to be displaceable, and each LED is connected to the inside of the connecting rod. Connected with embedded flexible board.

[0006]

[Action]

 With the above configuration, the LEDs are connected in a plane by the flexible substrate, and even by themselves, the LEDs have stronger durability than those connected by the wiring. Moreover, since this flexible substrate is embedded in the linking rod that mechanically connects the cases containing the LEDs, the linking rod substantially improves the mechanical strength and eliminates the risk of disconnection. Further, since the flexible substrate is located in the linking rod, it has a neat appearance and a good appearance. In addition, the flexible substrate does not obstruct the attachment to a wall or the like and can be easily attached.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a display device according to an embodiment of the present invention. In FIG. 1, 1 is a cylindrical case, and this case 1 is made of transparent or translucent silicon, and adjacent cases 1 are formed integrally with the case 1 (made of silicon). , Are connected in a straight line by the elastic connecting rod 2. Further, as shown in FIG. 2, a lens portion 1a for condensing or diffusing the light of the LED 3 contained in the case 1 is formed on the top portion (circular flat surface) of the case 1. Reference numeral 4 is a flexible substrate to which the electrode 3a of the LED 3 is soldered. In FIG. 1, reference numeral 5 is a female connecting portion formed at one end of the display device. Further, at the other end of the display device, a male connecting portion 6 that engages with the connecting portion 5 in a male and female manner is provided. Reference numeral 7 is a male socket extended from the connecting portion 5, 8 is a female socket extending from the connecting portion 6, and these sockets 7 and 8 are electrically connected to the flexible substrate 4. The LED 3 is also incorporated in the connecting portion 6. Here, as shown in FIG. 2, the flexible substrate 4 is embedded in the connecting rod 2 and the case 1, and the flexible substrate 4 is reinforced by the connecting rod 2 and the like. That is, even if a force in the bending direction acts on the display device, most of the force is supported by the connecting rod 2 and the like, and a large force does not act directly on the flexible substrate 2. Also, with respect to the flexible substrate 2 itself, the wiring in the conventional display device has a cross section made of thin dots, whereas the cross section has a rectangular surface, and even if a slight deformation occurs, the wire is not broken. Absent. The display device of the present invention comprises the components shown in FIG. 2 connected in a straight line, for example, about 100 pieces as shown in FIG. Here, since the case 1 can be formed to have a size of about 1.5 times the size of the LED 3, it is possible to perform a much finer display than a conventional display device using a light bulb.

As described above, the both ends of the display device are provided with the connecting portions 5 and 6 and the sockets 7 and 8 which engage with each other. If these connecting portions 5 and 6 and sockets 7 and 8 are used, a display device of a desired length can be obtained by connecting a plurality of display devices in series when the length of the display device is insufficient. . That is, as shown in FIG. 3, the connecting portion 5 at the rear end of the first display device A is engaged with the connecting portion 6 at the front end of the second display device B, and the first display device A and the second display device A are engaged. B is mechanically connected in series. As a result, a long display device in which the first display device A and the second display device B are connected to each other can be obtained. Here, the LED 3 is also incorporated in the connecting portion 6, and even if the first display device A and the second display device B are connected, the same LED is provided over the entire first display device A and the second display device B. The LEDs 3 are present at the pitch so that continuous display can be performed. At the same time, the socket 7 of the first display device A and the socket 8 of the second display device B are connected. Thereby, the LEDs 3 of the first display device A and the second display device B can be blinked by the same power supply device (not shown).

FIG. 4 shows an example of holding the display device. As described above, the display device of the present invention is flexible and bendable, but in order to maintain the shape once constructed, in this example, the top of the case 1 is inserted into the transparent or translucent suction cup 10. The suction cup 10 is sucked onto the glass plate 9. Of course, since the light of the LED 3 is transmitted through the case 1, the suction cup 10 and the glass plate 9, the light of the LED 3 is visually recognized even from the opposite side of the glass plate 9 to the surface on which the display device is attached (right side in FIG. 4). can do. Here, as the display form of the display device of the present invention, a specific figure is displayed on a signboard used for a road sign, it is arranged on the outer edge of a pavement, or a shop window, tent or wall surface of a storefront is displayed. There are various possibilities such as displaying logos and figures on the. Due to such a display mode, even if the display device is bent into an arbitrary shape, the disconnection is unlikely to occur as described above, and therefore it is possible to flexibly cope with it.
