Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signboard using a light source.

[0002]

2. Description of the Related Art In recent years, a lot of signboards showing characters and patterns with light sources such as neon tubes and miniature bulbs have come to be seen. In such a signboard, wiring is provided on the back side of the substrate on which the light source is attached. In addition, among signboards using such a light source, a board is newly formed with a half mirror, and a cover formed with a half mirror is provided on the surface of the board to maintain a gap between the board and the cover. In some cases, the image of light emitted from the light source is repeatedly reflected on the substrate and the cover, that is, the two half mirrors, and the light images are overlapped so that the light multiplex effect is obtained.

Conventionally, in such a signboard, since the light source is connected to the substrate through an optical fiber, a resin plate having a low transparency such as black is provided on the back side of the substrate so that the optical fiber cannot be seen through the front side of the cover. We are doing things such as pasting together.

[0004]

However, in such a conventional signboard, even if the optical fiber is hard to see from the front side of the cover because the resin plate with low transparency is attached to the back side of the substrate, When it is attached to a window such as, there is a problem that the resin plate interferes with the coloration and also blocks the line of sight. In addition, even if a light source such as a miniature light bulb is directly attached to the substrate like a general signboard using a light source, the wiring for connecting the light source to the power source must be done on the back side of the substrate, so that A resin plate with low transparency is required to hide the wiring,
Similar problems arise.

It is an object of the present invention to provide a signboard capable of obtaining an optical multiplex effect without obstructing the chromatic light or blocking the line of sight in view of the above problems.

[0006]

In order to achieve the above object, the signboard of the present invention comprises a substrate to which a light source is attached and a cover provided on the front side of the substrate.
An electrically conductive transparent substrate provided with a gap, the cover being formed of a half mirror, and the substrate being juxtaposed to a base body made of an electrically insulating material so as not to short-circuit a plurality of electrically conductive wires. It is formed of a plate and a half mirror joined to the front side of the conductive transparent plate, and the light source is connected to a conductive wire of the conductive transparent plate.

[0007]

In the signboard of the present invention, when the conductive wire of the conductive transparent plate is energized, the light source connected to this conductive wire emits light, and the image of the light repeatedly appears on the substrate and the cover, and the image of the light is formed. Looks like a lot of overlap.

That is, the conductive transparent plate 11 includes the conductive wire 113 and the electrically insulated wire 11 which form the conductive mesh 112.
Since an ultrafine element wire is used as 4, the whole looks like an achromatic or chromatic transparent body. The distance between the adjacent conductive wires 113 and the distance between the adjacent electrically insulating wires 114 are set in consideration of the transparency of the viewer. For example, diameter
When the conductive wire 113 and the electrically insulating wire 114 of about 0.1 mm are used, it is preferable to set the interval between the adjacent electrically conductive wires 113 and the interval between the adjacent electrically insulating wires 114 to be roughly 10 mm or more, and the diameter is about 20 μm. Conductive wire 113
When using the electric insulation line 114, it is preferable that the intervals between the adjacent conductive lines 113 and the intervals between the electric insulation lines 114 are closely set to about 1 mm.

The half mirror 12 may be an acrylic plate on one side of which metal is vapor-deposited, or a glass plate on which one side of metal is vapor-deposited. The metal to be vapor deposited includes aluminum and silver.

The light emitting diode 3 may be connected to one conductive line 113 or may be connected by converging a plurality of conductive lines 113 at their terminals. When connecting the light emitting diode 3 to the conductive wire 113, a hole may be formed in the substrate 1,
The conductive wire 113 can be exposed by removing the base portion 111 of the substrate 1 with a solvent and connected by soldering or a conductive adhesive (silver paste). In addition, these light emitting diodes 3 are arranged in an elliptical shape and are connected to different conductive lines 113.

The pedestal 4 is formed in a box shape,
The upper surface is provided with a recess 41 in which the lower ends of the substrate 1 and the cover 2 are fixed by insertion. In addition,
The recess 41 is formed so as to hold the substrate 1 and the cover 2 in a state of being tilted backward. Further, inside the pedestal 4, a controller 7 connected to the conductive wire 113 of the conductive transparent plate 11 inside the pedestal 4 via a connector or the like.

As described above, in the signboard of this embodiment, since the conductive wire 113 of the conductive transparent plate 11 can be used as a power feeding means to the light emitting diode 3, the wiring is not provided on the back side of the substrate 1, The light emitting diode 3 mounted on the substrate 1 can emit light. That is, since it is not necessary to provide a resin plate having low transparency on the back side of the substrate 1, it is possible to obtain an optical multiplex effect without disturbing chromatic light or blocking the line of sight.
