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 has developed 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 rod-shaped resin whose light-emitting surface is transparent at least. Various types of bendable light-emitting displays have already been proposed which are entirely encapsulated in a flexible envelope consisting of a filler.

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 does not undergo permanent deformation even when bent, it is difficult to maintain its bent shape even after bending. Therefore, the first
As shown in FIG. 0, when making a heart-shaped decorative lamp using the light-emitting display 100, a large number of fasteners 101 are used to keep the light-emitting display 100 in the shape of a heart. Display body 100
Each part must be fixed to the back windshield 50 of the automobile (or a support plate, a wall surface, etc.), and the fixing work using this large number of fasteners 101 is quite troublesome, and it is difficult to attach the parts directly to the glass surface. Fastening is impossible from the beginning, and a mounting portion must be formed on the glass 50 surface in advance.

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

(Means for solving the problem) Therefore, the present invention consists of a flexible envelope made of a rod-shaped resin filling whose light-emitting surface side is transparent, and a large number of wires connected by a plurality of conductive wires. In a light-emitting display body in which light-emitting elements are embedded in a row, a light-reflecting layer is formed on the back side of the flexible envelope opposite to the light-emitting surface side, and a light-reflecting layer is formed on the light-emitting surface of the flexible envelope. The gist is that a plurality of suction cups are provided at predetermined intervals in the length direction on the side or the surface opposite to the light emitting surface side.

(Function) With such a configuration, when the rod-shaped 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, that is, the light-emitting display is restored. This is prevented by the suction effect of the suction cup on the glass surface, and it becomes 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 embodiment of the light-emitting display of the present invention, and FIG. 2 is a cross-sectional view thereof, in which a large number of light-emitting elements 1 are arranged in a row. The cathode terminal 11 is connected to a conductive wire 21, the anode terminal 12 is connected to a conductive wire 22,
The light-emitting elements 1 are configured to emit light by connecting the conductive wires 21 and 22 to a power source. At this time, the number of conductive wires 21 and 22 may be increased to selectively emit light from the light emitting elements 1.

The 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 8th
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.

These light emitting elements 1... and conductive wires 21, 21
is embedded in the flexible envelope 3 so that the rows of light-emitting elements are located along the center line, thereby forming the intended light-emitting display. This flexible envelope 3 is
A flexible rod made of a resin filling (sealing resin) such as soft polyvinyl chloride resin, acrylic resin, polyethylene resin, polycarbonate resin, silicone rubber, etc., and the entire body is translucent, preferably containing light. A resin mixed with a light reflecting agent such as aluminum flakes, or A light reflecting layer 32 is formed by metal vapor deposition or the like. The flexible envelope 3 may be made of colored semi-transparent resin to enhance the display effect.

Further, on the light emitting surface 31 side of the flexible envelope 3, a plurality of circular or rectangular soft synthetic resin suction cups 4 are provided at predetermined intervals in the length direction. It is desirable that this suction cup 4 be transparent;
The structure of the mounting part is configured as shown in the figure, that is, a mounting part 41 having an annular groove 42 is integrally formed on the back side of the suction cup 4, and the light emitting surface 31 of the flexible envelope 3
A recess 33 that fits the attachment part 41 is formed on the side, and the attachment part 41 is elastically deformed and fitted into the recess 33, so that the suction cup 4 is attached to the flexible envelope 3. ing. Note that the attachment of the suction cup 4 to the flexible envelope 3 is not limited to the structure described above, but may be fixed with an adhesive, or by attaching the suction cup 4 to the flexible envelope 3 as shown in FIG. In particular, when the flexible envelope 3 is molded as shown in FIG. 6, the suction cup 4 is simultaneously molded from the same material, and as shown in FIG. The surface 31 may be curved concavely to form the suction cup 4.

However, the suction cup 4 may be provided on the back surface of the flexible envelope 3 on the side opposite to the light emitting surface 31. In this case, it is suitable for mounting on a support plate for neon signs, guide lights, etc. In this case, it is suitable for attachment to the inner surface of a transparent plate such as an automobile's back window glass or display glass.

However, when the light emitting display having the above structure is bent into an arbitrary shape and attached to the back window glass 5 of an automobile as shown in FIG. In this state, the flexible envelope 3 presses the suction cups 4 to compress and deform them, and the air in the suction cups 4 is pushed out to fix them by suction. It will retain its shape in a bent state.

Furthermore, since the light-emitting elements 1 are arranged almost along the center line of the flexible envelope 3, elongation due to bending of the light-emitting display body is difficult to apply to the light-emitting elements 1. There is no possibility of adverse effects, and reliability is improved.

In addition, when the light emitting display of the present invention is attached to the back windshield of a car and used as a decorative light of the car, a conductive wire is connected to the electric circuit of the brake lamp, and when the brake pedal is depressed, it lights up together with the brake lamp. It may be configured as a decorative light that has 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.

(Effect of the invention) As explained above, according to the light emitting display according to the invention, a plurality of conductive wires are connected within a flexible envelope made of a rod-shaped resin filler whose light-emitting surface side is transparent. In a light-emitting display body formed by embedding a large number of light-emitting elements in a row, a light-reflecting layer is formed on the back side of the flexible envelope opposite to the light-emitting surface side, and the flexible envelope Since a plurality of suction cups are provided at predetermined intervals in the length direction on the light-emitting surface side of the body or on the surface opposite to the light-emitting surface side, this rod-shaped flexible envelope can be shaped into any shape. By bending it, you can create original things such as brake lights or decorative lights of any shape on the back window glass or side window glass of a car.Moreover, the light emitting display can be bent at predetermined intervals along the length of the light emitting display. By sequentially adhering multiple suction cups provided on the glass surface to the glass surface, the bent shape of the light emitting display can be maintained in a predetermined shape, and there is no need for special and numerous mounting tools, making it extremely easy to install decorative lights. It can be made easily and efficiently.

Furthermore, since all the suction cups are provided on the light-emitting surface side of the flexible envelope or on the side opposite to the light-emitting surface side, it is possible to attach these suction cups to the back windshield or side window glass of a car. Therefore, the light-emitting display can be mounted with the light-emitting surface facing in a certain direction over its entire length.
This makes it possible to further improve the decorative effect.
