Description

[Detailed description of the invention] (Industrial application field) This invention is used for display decoration lights and neon signs that are attached to glass surfaces such as store windows, or for braking devices that are attached to back windows and side windows of automobiles. It relates to light-emitting display bodies used in lamps, decorative lights, etc.

(Prior Art) The present applicant proposed such a light-emitting display by arranging a large number of light-emitting elements in a row and connecting them to a plurality of conductive wires, and using a flexible display with at least the light-emitting surface side transparent. Various types of bendable light-emitting displays have already been proposed which are entirely encapsulated with an envelope.

These light-emitting displays can be bent in any direction,
Although this is a convenient tool that allows complex bending to be performed freely, there are still some points that need to be improved, such as the following.

(Problems to be Solved by the Invention) That is, since the above-mentioned light-emitting display hardly causes permanent deformation when bent, it is difficult to maintain its bent shape even if it is bent. Therefore, the 9th
As shown in the figure, when manufacturing a heart-shaped decorative lamp using the light-emitting display 100, a large number of fasteners 101 are used to display the light-emitting display in order to keep the light-emitting display 100 in a heart shape. It is necessary to fix each part of the body 100 to the back windshield 50 (or support plate, wall surface, etc.) of the automobile, and this fixing work using a large number of fasteners 101 is quite troublesome. It is almost impossible to attach the glass 50 directly, and a mounting portion must be formed on the glass 50 surface in advance.

The present invention was devised to solve this problem, and allows the backwind to be bent into an arbitrary shape and maintain that bent shape without requiring a large number of fasteners or attachment parts as described above. It is an object of the present invention to provide a light-emitting display that can be attached to glass or the like extremely simply and efficiently.

(Means for Solving the Problems) Therefore, the present invention is a fixture for a light-emitting display body, which has a large number of light-emitting elements arranged in a transparent, bendable, rod-shaped resin flexible envelope. forming a spherical recess on one of the surface of the flexible envelope and the back surface of the suction cup, and forming a spherical bulge on the other that fits into the spherical recess, or
A holder body is inserted into an appropriate position of the flexible envelope, and a spherical recess is formed on either the holder body or the back surface of the suction cup, and a spherical bulge that fits into the spherical recess is formed on the other side. The gist is that the suction cup is rotatably and swingably supported on the light emitting display.

(Function) With such a configuration, when the light-emitting display is bent into an arbitrary shape such as a heart shape, this bent shape is maintained by suction to the glass surface of the suction cup. This is prevented by adsorption to the surface, making it possible to maintain the shape of the light-emitting display in an arbitrary bent shape.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a plan view showing an example of a light emitting display;
FIG. 2 is a cross-sectional view of the same, in which a large number of light emitting elements 1 are arranged in a row, the cathode side terminal 11 of each element 1 is connected to the conductive wire 21, and the anode side terminal 12 is connected to the conductive wire 22. By connecting these conductive wires 21 and 22 to the power source, the light emitting body 1
It is configured to emit light. At this time, the number of conductive wires 21 and 22 is increased, and the light emitting element 1...
It may be configured to selectively emit light.

This light emitting element 1 is made of a solid state lamp as shown in FIG. 3, and includes a semiconductor chip 13 such as a known light emitting diode such as gallium arsenide (GaAs), gallium aluminum arsenide (GaAlAs), gallium phosphide (GaP), etc. Translucent thermosetting resin 1
A cathode side terminal 11 embedded in the chip 13 and an anode side terminal 12 connected to the chip 13 via a bonding wire 15 protrude to the outside.

On the other hand, the conductive wires 21 and 22 are both made of copper wire covered with an insulating film, and the connection portion with the light emitting element 1 is made into a bare wire by removing the insulating film, and this bare wire portion is Terminal 1 of light emitter element 1
1 and 12 are connected by means such as soldering. In addition, when using bare wires as the conductive wires 21 and 22, after connecting the connection terminals 11 and 12 of the light emitting element 1 by means such as soldering, apply varnish or the like made of various resins such as polyurethane resin. It may be used as an insulating film. Also, both conductive wires 2
1 and 22 may be simply arranged in parallel, but the seventh
As shown in the figure, the light emitter elements are crossed every 1 space,
It may be made to meander as shown in FIG.
Alternatively, a tensile force acts on the conductive wire 22 or a compressive force acts on the conductive wire 22 or 21 which becomes inside when bent. These conductive wires 21, 22
The absorption and relaxation of elongation acting on the material is not limited to this structure, and may be any structure.

A light-emitting display A is formed by enclosing these light-emitting elements 1 and conductive wires 21 and 22 with a flexible envelope 3 such that the rows of light-emitting elements 1 are located along the center line. There is. The flexible envelope 3 is made of soft polyvinyl chloride resin, acrylic resin, polyethylene resin, polycarbonate resin, silicone rubber, etc., and has a flexible rod shape with a circular or square cross section, and has translucency as a whole. It is preferably configured to have light diffusing properties by containing a light diffusing agent, and the side opposite to the light emitting surface is made of a resin mixed with a light reflecting agent such as aluminum flakes, or by metal vapor deposition. A reflective layer 31 is formed. The flexible envelope 3 may be made of colored semi-transparent resin to enhance the display effect.

Therefore, in the present invention, a suction cup 4 is supported on the light-emitting display A having the above structure, and the light-emitting display A is attached to the back window glass of an automobile by means of the suction cup 4.

The supporting structure of the suction cup 4 to the light-emitting display A includes forming a spherical recess 32 on one of the light-emitting display A and the suction cup 4, for example, on the light-emitting surface side of the flexible envelope 3 of the light-emitting display A. , a spherical bulge 41 is formed on the back surface of the other suction cup 4 on the side opposite to the suction surface thereof;
The bulging portion 41 is fitted into the recess 32 to allow the light emitting display A to support the suction cup 4 rotatably and swingably. At this time, the suction cup 4 is desirably made of transparent synthetic resin so as not to interfere with light emission.

In the above embodiment, the suction cup 4 is directly supported by the light-emitting display body A, but the structure is not limited to this. For example, as shown in FIG. The holder body 5 may be configured to be supported by the light emitting display A, that is, a holder body 5 having a circular through hole 51 is formed, a spherical recess 52 is formed in the body 5, and the holder body 5 is
The spherical convex portion 41 of the suction cup 4 is fitted into the spherical concave portion 52 of the holder body 5, and the light emitting display body A is inserted into the through hole 51 of the holder body 5. Further, this holder body 5 has a recess 52 as shown in FIG.
It can be opened and closed by separating it at the opposite side, and a bulging part 53 is formed on one side of the separating part, and a recess 54 is formed on the other side of the separating part, and by fitting the bulging part 53 into the recess 54. , the separation part of the holder body 5 may be configured to be closed; in this case, the holder body 5 may be closed.
The light emitting display body A can be easily and freely inserted into the through hole 51 at any position.

In this way, when the flexible light-emitting display A is bent into an arbitrary shape and attached to the back window glass 6 of an automobile as shown in FIG. 4, the spherical recess 32 of the light-emitting display A Alternatively, the spherical bulge 41 of the suction cup 4 is fitted into the spherical recess 52 of the holder body 5, and the suction cup 4 is rotatably and swingably supported by the light-emitting display A directly or via the holder body 5; This sucker 4
The light-emitting display body A having the following properties is attached to the back window glass 6 by suctioning the suction cup 4 to the inner surface of the back window glass 6. At this time, by rotating the light-emitting display body A within the through hole 51 of the holder body 5, the direction of light emitted from the light-emitting display body A can be changed, and the position at which the suction cup 4 is attracted to the glass 6 can be changed to a light-emitting display. By matching the bent state of the body A, an arbitrary bent shape such as a heart shape can be maintained.In particular, since the suction cup 4 can be rotated and swung relative to the light emitting display body A, the glass 6 of the suction cup 4 The suction to the light-emitting display body A can be carried out simply by setting the suction position without considering the direction of the light-emitting display body A. That is, the holder main body 5 rotates and swings to follow the bending direction of the light-emitting display body A.

In addition, when the light-emitting display A is attached to the back window glass of a car as described above and used as a decorative light of the car, the conductive wires 21 and 22 are connected to the electric circuit of the brake lamp, so that when the brake pedal is depressed, It may be configured to be lit together with a bookie lamp, and serve as a decorative light that serves both a decorative function and a braking display function.

It is also natural that it can be used as a brake light to supplement a brake light without having the decorative function as described above.

(Effects of the invention) As explained above, the light-emitting display mounting tool according to the present invention is extremely simple, easy, and reliable by adsorbing the light-emitting display to a glass surface etc. with a suction cup while the light-emitting display is bent into an arbitrary shape. Moreover, this attachment maintains the bent shape, and in particular, since the suction cup can be rotated and swung relative to the light-emitting display, the adsorption of the suction cup to the glass, etc. There is no need to consider the orientation of the light-emitting display at the bending part, it is only necessary to set the suction position, and the bending shape of the light-emitting display can be maintained extremely easily and without the need for many special fasteners. They were able to get it done without any problems.
