Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-light signboard device, and more particularly, to an internally illuminated signboard device using a flexible reflection sheet capable of reducing the number of lights.
By devising the support structure of the reflection sheet, even in a large signboard device requiring a large reflection sheet, a small electric lamp capable of reliably increasing the illuminance by holding the reflection sheet in an appropriate shape. The present invention relates to a signboard device.

[0002]

2. Description of the Related Art An internally illuminated signboard device that has already been put into practical use includes an electric lamp housing case provided with a light-transmissible advertising display board in a front opening portion, and an electric lamp housed in the case. There is something. However, in this internally illuminated signboard device, the light passing through the rear surface of the case is diffusely reflected by the rear surface of the case, so that less light passes through the display panel. As a result, the display becomes dark because sufficient illuminance cannot be secured, and the number of electric lights must be increased to obtain the required illuminance.

[0003] As an internally illuminated signboard device which solves this problem, a reflector bent in a groove shape is arranged so that its bottom is located behind the lamp and its side wall is located on the side of the lamp. Some have been set up. This signboard device has an advantage that the number of electric lights can be reduced as compared with a device without a reflection plate, because the amount of light transmitted through the advertisement display plate is increased by the reflection plate. However, the conventional reflecting plate has been formed by cutting a metal plate such as stainless steel in accordance with the size and shape of the electric lamp housing case, and bending or bending the metal plate into a groove shape. Since the reflector made of a metal plate is heavy, when it is applied to a large internally illuminated signboard, the assembling work must be performed by a plurality of persons, and there is a problem that workability is poor. Further, it is difficult to perform a cutting process, a bending process, and a bending process on a reflecting plate made of a metal plate on site. Since there are various sizes and shapes of lamp housing cases, the size and shape of the reflector must necessarily be changed accordingly, but the reflector made of a metal plate must be In order to apply to cases with different sizes and shapes, it is necessary to change the design one by one and then pre-mold at the factory.
Therefore, there is a problem that this reflector is not suitable for mass production.

[0004] In recent years, there has been proposed a reflection sheet formed by laminating an aluminum film on the surface of a resin sheet. This reflection sheet has elasticity, and as an internally illuminated display device using such a reflection sheet, for example,
The following have been proposed: That is, the positive film is fitted into the front opening of the box-shaped case, and the holding protrusions are formed on the back side of the opposite edges in the front opening, and the reflection sheet is provided on the inner surface of each holding protrusion. There has been proposed a positive film viewing device in which a reflecting sheet is curved between the holding convex portions so that the leading end of the positive film abuts. In this viewing device, the reflection sheet holds an arc shape by its own elastic force, that is, shape restoring force.

[0005]

When the above-mentioned reflection sheet is applied to a relatively small device such as a positive film viewing device, it is possible to maintain a curved shape by its own elastic force. , Such a support structure,
It cannot be applied to large internally illuminated signboard devices. In other words, the reflective sheet in a large-sized internally illuminated signboard device becomes very heavy, so with a support structure that simply sandwiches the reflective sheet between the opposing convex portions, the reflective sheet bends more than necessary due to its own weight, or The surface will be wavy. As a result, there is a possibility that the signboard device cannot sufficiently increase the illuminance, and the reflection sheet may fall off from the projection. In addition, with a support structure that is simply sandwiched between opposing convex portions, the delicate inclination angle of the reflection sheet cannot be adjusted, and sufficient illuminance cannot be achieved.

[0006] The present invention has been made in view of such circumstances, and a large-size internally illuminated signboard device can be provided by using a flexible reflective sheet and devising a support structure for the reflective sheet. An object of the present invention is to provide a low-light signboard device capable of holding a reflection sheet in an appropriate shape and securing high illuminance even with a small number of lights.

[0011]

Embodiments of the present invention will be described with reference to the drawings. The small light signboard device according to the present invention is roughly divided into a single-sided signboard device (A) illustrated in FIG. 21, a double-sided signboard device (B) illustrated in FIG. 22, and FIG. 23. There are three types of tubular signboard devices (C). First, an embodiment of a single-sided display signboard device will be described.

FIG. 1 and FIG. 2 are views showing a first embodiment of a low light signboard device according to the present invention. The small-light signboard device according to the first embodiment is a single-sided signboard device, and includes a lamp housing case (3) provided with a light-transmissible advertising display plate (2) in a front opening (1); The case (3) comprises a linear electric lamp (4) and a reflection sheet (5) housed in the case (3). Hereinafter, these components will be sequentially described in detail.

An advertisement display board (2) (hereinafter, referred to as a display board (2)) is provided with a front opening (1) of a lamp housing case (3).
It is mounted on the front surface of the lamp housing case (3) so as to cover (see FIG. 1). The display plate (2) is made of a light transmissive material. Although the type of the material is not particularly limited, for example, a synthetic resin such as an acrylic resin can be adopted. In addition, desired advertising characters and designs are described on the display plate (2), or a photographic film is attached thereto.

The light accommodating case (3) accommodates the linear electric light (4) and the reflection sheet (5).
The shape of the lamp housing case (3) is not particularly limited as long as an opening is formed on the front surface, and is, for example, a rectangular parallelepiped. Further, the material is not particularly limited. For example, various metals such as steel and aluminum, various synthetic resins such as an acrylic resin, and wood having a surface subjected to a water-repellent treatment can be used. In some cases, a magnet is fixed to the lamp housing case (3) by magnetic force. In this case, it is desirable to use a ferromagnetic material such as steel as the material.

The linear lamp (4) (hereinafter referred to as the lamp (4)) is disposed in the lamp housing case (3). The type of the electric light (4) is not particularly limited, but a fluorescent light is preferably used. In the illustrated example, both ends of the lamp (4) are held by a lamp holder (6), and power is supplied through the holder (6). The support structure of the lamp holder (6) is not particularly limited, but can be supported by, for example, a holder support member (7) as shown in FIG. The holder support member (7) is an L-shaped member in the example shown in FIG. 3, and has two screw insertion holes (9) formed in its bottom plate (8). A screw (10) (see FIG. 2) is screwed into the holder so that the holder support member (7) can be fixed to the back plate (11) (see FIG. 1) of the electric lamp housing case (3).

The fixing method of the holder supporting member (7) is not limited to screw fixing. For example, a magnet (not shown) is provided on the back side of the holder supporting member (7), and the electric lamp is housed by the magnetic force of the magnet. It may be fixed to the case (3). Further, the form of the holder support member (7) is not limited to that shown in FIG. 3, but may be as shown in FIG. In this example, the holder supporting member (7) is substantially a plate material.
The upper plate (12) is provided with two wire support portions (32). Further, a screw insertion hole (9) is formed in the rising portion (13) of the holder support member (7), and a screw (not shown) is screwed into the screw insertion hole (9) to thereby provide an electric lamp. The holder support member (7) can be fixed to the side plate (14) (see FIG. 2) of the storage case (3).

The reflection sheet (5) efficiently reflects the light of the electric lamp (4) and increases the amount of light transmitted through the display panel (2). This reflection sheet (5) is flexible and can be bent or curved into any shape. The structure and material of the reflection sheet (5) are not particularly limited as long as it is flexible. For example, a sheet formed by depositing an aluminum film on one surface of a colorless and transparent synthetic resin sheet can be used.

It is preferable that the reflection sheet (5) be the one shown in FIG. The reflection sheet (5) shown in FIG. 5A includes a base sheet (15) made of a synthetic resin, an aluminum film (16) deposited and laminated on the upper surface of the base sheet (15), and the aluminum film. (1
And a topsheet (17) laminated on the upper surface of (6) and made of colorless and transparent synthetic resin. Since the reflection sheet (5) is reinforced by the base sheet (15), it does not expand or tear even when pulled by the coil spring (24) (see FIG. 1) or the like. In addition, a reinforcing tape (60) (FIG.
4 (a)), and the reinforcing tape (60)
It is preferable that the portion reinforced by is pulled by a coil spring (24) or the like. Thereby, the reflection sheet (5) becomes a sheet that is more resistant to tension. This reinforcing tape (60) is, as shown in FIGS.
It is appropriately attached according to the position where the tension fixing means (23) such as the coil spring (24) is provided.

In the reflection sheet (5), bone-white polyethylene terephthalate resin is used as the material of the base sheet (15). The reason is that polyethylene terephthalate resin has much higher heat resistance and weather resistance than other synthetic resins such as acrylic resin, so that it can sufficiently withstand high temperature heating by an electric lamp (4). It is. Further, by making the base sheet (15) have a bone white color, a mirror-like action is generated on the base sheet (15), and the reflectance of the reflection sheet (5) is significantly improved. It is also desirable to use polyethylene terephthalate resin for the material of the topsheet (17) from the viewpoint of heat resistance and weather resistance.

The structure of the reflection sheet (5) is shown in FIG.
The configuration shown in FIG. 5A is not limited to the example shown in FIG. The reflection sheet (5) shown in FIG.
Consists essentially of a base sheet (15), an aluminum film (16), and a topsheet (17), as shown in FIG. 5 (a), but is further oxidized on the topsheet (17). The difference from the example of FIG. 5A is that a titanium layer (53) is formed. Since titanium oxide is a photocatalyst that reacts to ultraviolet light, the titanium oxide layer (53) can oxidatively decompose a substance on itself in response to the ultraviolet light of the electric lamp (4). Therefore, it is possible to sterilize the inside of the low light signboard device and exhibit antifouling properties so as not to stain the inside of the device.

The reflection sheet (5) thus configured
Is disposed in the lamp housing case (3) in a state of being bent in a groove shape. The reflection sheet (5) is pressed by a wire (18) provided so as to cross the sheet (5), whereby the reflection sheet (5) is bent into a desired shape. Although the bent shape is not particularly limited, for example, as shown in FIG. 1, four places are bent by four wires (18), whereby the flat bottom (19) and the middle part are bent. And a side wall (20). The bottom (19) is located behind the lamp (4) and the side wall (20) is located on the side of the lamp (4).

The front edge portion of the reflection sheet (5), that is, the tip portion (21) of the side wall portion (20) is located at the lamp housing case (3).
Tension fixing means (2) provided near the opening edge (22) of the
3) is pulled towards the opening edge (22).
Thereby, it is possible to prevent the entire reflecting sheet (5) from being loosened. The configuration of the tension fixing means (23) is not particularly limited. For example, as shown in FIG. 2, a tension coil spring (24) (hereinafter, referred to as a coil spring (24))
And a spring fixing member (25). As shown in FIG. 6, the spring fixing member (25) has a holding portion (26) having a U-shaped cross section and a spring locking portion (27) for locking one end of the coil spring (24). The upper end of the side plate (14) (see FIG. 2) of the lamp housing case (3) can be sandwiched by the sandwiching portion (26). An eyelet (28) (see FIG. 2) is provided at the end (21) of the reflection sheet (5), and the other end of the coil spring (24) is locked to the eyelet (28). The provision of the eyelet (28) can prevent the tip (21) of the reflection sheet (5) from being broken by the tensile force of the coil spring (24). Further, by providing the stopper (28) at the portion where the reinforcing tape (60) (see FIG. 24) is adhered, the tensile strength of the reflection sheet (5) can be more reliably increased.

Both ends of the wire (18) are fixed to the inner surface of the side plate (14) of the lamp housing case (3). The fixing method is not particularly limited. For example, the fixing can be performed using the magnetic force of a magnet. FIG. 7 is a view showing an example of a wire fixing member (30) having a magnet (29). The wire fixing member (30) includes a rectangular parallelepiped magnet (29) and a cover material (3) that covers the upper surface and two side surfaces of the magnet (29).
1) and a substantially L-shaped wire support portion (32) fixed on the cover material (31). Magnet (2
9), the cover material (31), and the wire support portion (32)
It is integrated by the screw (33) and the nut (34). The through-hole (3) is provided at the rising portion of the wire support portion (32).
5) is formed, and the wire (1) is inserted into the through hole (35).
8) is locked at one end. One end of the wire (18)
After being inserted into the through-hole (35), it is locked in the through-hole (35) by being flattened or bent.

Next, a method of assembling the low light signboard device will be described. This low light signboard device may be manufactured by renewing an existing internally illuminated signboard device, or may be newly manufactured. First, the case of renewal production will be described. First, the display board (2) is removed, and then the existing light (not shown) is removed. Usually, the existing lamps are fluorescent lamps and many lamps are arranged, but all of these lamps are removed. The existing light holder (not shown) may be removed, but may be left as it is.

Next, the lamp holder (6) of the present invention is placed in the lamp housing case (3). At this time, the holder supporting member (7) shown in FIG. 3 or the holder supporting member (7) shown in FIG. 4 may be used, but the holder supporting member (7) shown in FIG. The holder (6) is attached to the back plate (1) of the lamp housing case (3).
1) Since it can be provided at a position far away from (see FIG. 1), it can be suitably used when the existing lamp holder is left.

Next, the wire (18) is attached to the electric light housing case (3). At this time, the wire fixing member (30)
The magnet (29) of the rear panel (1)
Fix magnetic force to 1). A plurality of wires (18) are usually used, and their positions are not particularly limited.
In the example shown in (4), four wires (18) are provided in parallel with the longitudinal direction of the lamp (4), and two wires (18) are provided on both sides of the lamp (4). Then, on each side of the lamp (4), one wire (18) is provided near the lamp (4) and slightly behind the lamp (4), and the other wire (18) is located near the lamp (4). ) Is provided slightly forward of the electric light (4). Position adjustment of the front and rear of the wire (18) can be adjusted by the height of the wire support (32) in the wire fixing member (30).

Next, one end (2) of the reflection sheet (5)
1) is provided with a stop (28), and a spring fixing member (2) is provided on the upper end of the side plate (14) of the lamp housing case (3).
5) The holding portion (26) is fixed. Then, the other end of the coil spring (24) is engaged with the fitting (28). In this state, the reflection sheet (5) is sunk under each wire (18), and the opposite end of the reflection sheet (5) is placed near the upper end of the side plate (14) on the opposite side of the lamp housing case (3). Position. At this time, if the reflection sheet (5) is too long and becomes loose, it is cut to an appropriate length. A stop (28) is provided at the tip (21), and a holding portion (26) of a spring fixing member (25) is fixed to the upper end of the side plate (14) on the opposite side of the lamp housing case (3). I do. afterwards,

1) is pulled toward the opening edge (22) of the lamp housing case (3) by the coil spring (24). Accordingly, the entire reflection sheet (5) is in a state without slack, and the reflection sheet (5) can surely reflect the light of the electric lamp (4) in a desired direction. In addition, since each wire (18) is attached to the lamp housing case (3) by the magnet (29), it can be moved as needed. Therefore, each wire (18) can be moved so that an appropriate inclination angle can be given to the reflection sheet (5) before or after disposing the reflection sheet (5).

It is desirable that a light diffusion sheet (36) be attached to a portion of the reflection sheet (5) facing the electric lamp (4). By providing the light diffusing sheet (36) (see FIGS. 1 and 2), the light of the electric lamp (4) is irregularly reflected at the portion where the electric lamp (4) is disposed. Therefore, it is possible to prevent the shape of the electric light (4) from appearing to be raised.

Next, the electric light (4) is placed in the electric light holder (6).
Attach. Thereafter, the display plate (2) is attached to the front opening (1) of the lamp housing case (3), and the assembling operation of the low light signboard device is completed.

Next, the case of new production will be described.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-light signboard device, and more particularly, to an internally illuminated signboard device using a flexible reflection sheet capable of reducing the number of lights.
By devising the support structure of the reflection sheet, even in a large signboard device requiring a large reflection sheet, a small electric lamp capable of reliably increasing the illuminance by holding the reflection sheet in an appropriate shape. The present invention relates to a signboard device.

[0002]

2. Description of the Related Art An internally illuminated signboard device that has already been put into practical use includes an electric lamp housing case provided with a light-transmissible advertising display board in a front opening portion, and an electric lamp housed in the case. There is something. However, in this internally illuminated signboard device, the light passing through the rear surface of the case is diffusely reflected by the rear surface of the case, so that less light passes through the display panel. As a result, the display becomes dark because sufficient illuminance cannot be secured, and the number of electric lights must be increased to obtain the required illuminance.

[0003] As an internally illuminated signboard device which solves this problem, a reflector bent in a groove shape is arranged so that its bottom is located behind the lamp and its side wall is located on the side of the lamp. Some have been set up. This signboard device has an advantage that the number of electric lights can be reduced as compared with a device without a reflection plate, because the amount of light transmitted through the advertisement display plate is increased by the reflection plate. However, the conventional reflecting plate has been formed by cutting a metal plate such as stainless steel in accordance with the size and shape of the electric lamp housing case, and bending or bending the metal plate into a groove shape. Since the reflector made of a metal plate is heavy, when it is applied to a large internally illuminated signboard, the assembling work must be performed by a plurality of persons, and there is a problem that workability is poor. Further, it is difficult to perform a cutting process, a bending process, and a bending process on a reflecting plate made of a metal plate on site. Since there are various sizes and shapes of lamp housing cases, the size and shape of the reflector must necessarily be changed accordingly, but the reflector made of a metal plate must be In order to apply to cases with different sizes and shapes, it is necessary to change the design one by one and then pre-mold at the factory.
Therefore, there is a problem that this reflector is not suitable for mass production.

[0004] In recent years, there has been proposed a reflection sheet formed by laminating an aluminum film on the surface of a resin sheet. This reflection sheet has elasticity, and as an internally illuminated display device using such a reflection sheet, for example,
The following have been proposed: That is, the positive film is fitted into the front opening of the box-shaped case, and the holding protrusions are formed on the back side of the opposite edges in the front opening, and the reflection sheet is provided on the inner surface of each holding protrusion. There has been proposed a positive film viewing device in which a reflecting sheet is curved between the holding convex portions so that the leading end of the positive film abuts. In this viewing device, the reflection sheet holds an arc shape by its own elastic force, that is, shape restoring force.

[0005]

When the above-mentioned reflection sheet is applied to a relatively small device such as a positive film viewing device, it is possible to maintain a curved shape by its own elastic force. , Such a support structure,
It cannot be applied to large internally illuminated signboard devices. In other words, the reflective sheet in a large-sized internally illuminated signboard device becomes very heavy, so with a support structure that simply sandwiches the reflective sheet between the opposing convex portions, the reflective sheet bends more than necessary due to its own weight, or The surface will be wavy. As a result, there is a possibility that the signboard device cannot sufficiently increase the illuminance, and the reflection sheet may fall off from the projection. In addition, with a support structure that is simply sandwiched between opposing convex portions, the delicate inclination angle of the reflection sheet cannot be adjusted, and sufficient illuminance cannot be achieved.

[0006] The present invention has been made in view of such circumstances, and a large-size internally illuminated signboard device can be provided by using a flexible reflective sheet and devising a support structure for the reflective sheet. An object of the present invention is to provide a low-light signboard device capable of holding a reflection sheet in an appropriate shape and securing high illuminance even with a small number of lights.

[0011]

Embodiments of the present invention will be described with reference to the drawings. The small light signboard device according to the present invention is roughly divided into a single-sided signboard device (A) illustrated in FIG. 21, a double-sided signboard device (B) illustrated in FIG. 22, and FIG. 23. There are three types of tubular signboard devices (C). First, an embodiment of a single-sided display signboard device will be described.

FIG. 1 and FIG. 2 are views showing a first embodiment of a low light signboard device according to the present invention. The small-light signboard device according to the first embodiment is a single-sided signboard device, and includes a lamp housing case (3) provided with a light-transmissible advertising display plate (2) in a front opening (1); The case (3) comprises a linear electric lamp (4) and a reflection sheet (5) housed in the case (3). Hereinafter, these components will be sequentially described in detail.

An advertisement display board (2) (hereinafter, referred to as a display board (2)) is provided with a front opening (1) of a lamp housing case (3).
It is mounted on the front surface of the lamp housing case (3) so as to cover (see FIG. 1). The display plate (2) is made of a light transmissive material. Although the type of the material is not particularly limited, for example, a synthetic resin such as an acrylic resin can be adopted. In addition, desired advertising characters and designs are described on the display plate (2), or a photographic film is attached thereto.

The light accommodating case (3) accommodates the linear electric light (4) and the reflection sheet (5).
The shape of the lamp housing case (3) is not particularly limited as long as an opening is formed on the front surface, and is, for example, a rectangular parallelepiped. Further, the material is not particularly limited. For example, various metals such as steel and aluminum, various synthetic resins such as an acrylic resin, and wood having a surface subjected to a water-repellent treatment can be used. In some cases, a magnet is fixed to the lamp housing case (3) by magnetic force. In this case, it is desirable to use a ferromagnetic material such as steel as the material.

The linear lamp (4) (hereinafter referred to as the lamp (4)) is disposed in the lamp housing case (3). The type of the electric light (4) is not particularly limited, but a fluorescent light is preferably used. In the illustrated example, both ends of the lamp (4) are held by a lamp holder (6), and power is supplied through the holder (6). The support structure of the lamp holder (6) is not particularly limited, but can be supported by, for example, a holder support member (7) as shown in FIG. The holder support member (7) is an L-shaped member in the example shown in FIG. 3, and has two screw insertion holes (9) formed in its bottom plate (8). A screw (10) (see FIG. 2) is screwed into the holder so that the holder support member (7) can be fixed to the back plate (11) (see FIG. 1) of the electric lamp housing case (3).

The fixing method of the holder supporting member (7) is not limited to screw fixing. For example, a magnet (not shown) is provided on the back side of the holder supporting member (7), and the electric lamp is housed by the magnetic force of the magnet. It may be fixed to the case (3). Further, the form of the holder support member (7) is not limited to that shown in FIG. 3, but may be as shown in FIG. In this example, the holder supporting member (7) is substantially a plate material.
The upper plate (12) is provided with two wire support portions (32). Further, a screw insertion hole (9) is formed in the rising portion (13) of the holder support member (7), and a screw (not shown) is screwed into the screw insertion hole (9) to thereby provide an electric lamp. The holder support member (7) can be fixed to the side plate (14) (see FIG. 2) of the storage case (3).

The reflection sheet (5) efficiently reflects the light of the electric lamp (4) and increases the amount of light transmitted through the display panel (2). This reflection sheet (5) is flexible and can be bent or curved into any shape .

[0018] reflection sheet (5) may adopt those illustrated in FIG. The reflection sheet (5) shown in FIG. 5A is a base sheet (15) made of a synthetic resin.
And an aluminum film (16) deposited and laminated on the upper surface of the base sheet (15), and a surface sheet (17) composed of a colorless and transparent synthetic resin laminated on the upper surface of the aluminum film (16). ing. This reflection sheet (5)
Is reinforced by the base sheet (15),
Even if it is pulled by the coil spring (24) (see FIG. 1) or the like, it does not expand or break. Also, a reinforcing tape (60) (FIG. 24) is provided on the edge surface of the reflection sheet (5).
It is preferable that a portion reinforced by the reinforcing tape (60) is pulled by a coil spring (24) or the like. Thereby, the reflection sheet (5)
Is a sheet that is even more resistant to tension. As shown in FIGS. 24A and 24B, the reinforcing tape (60) is appropriately attached according to the position where the tension fixing means (23) such as the coil spring (24) is provided.

In the reflection sheet (5), bone-white polyethylene terephthalate resin is used as the material of the base sheet (15). The reason is that polyethylene terephthalate resin has much higher heat resistance and weather resistance than other synthetic resins such as acrylic resin, so that it can sufficiently withstand high temperature heating by an electric lamp (4). It is. Further, by making the base sheet (15) have a bone white color, a mirror-like action is generated on the base sheet (15), and the reflectance of the reflection sheet (5) is significantly improved. Moreover, also the material of the topsheet (17), a polyethylene terephthalate resin can remain use <br/> terms of heat resistance and weather resistance.

The structure of the reflection sheet (5) is shown in FIG.
The configuration shown in FIG. 5A is not limited to the example shown in FIG. The reflection sheet (5) shown in FIG.
Consists essentially of a base sheet (15), an aluminum film (16), and a topsheet (17), as shown in FIG. 5 (a), but is further oxidized on the topsheet (17). The difference from the example of FIG. 5A is that a titanium layer (53) is formed. Since titanium oxide is a photocatalyst that reacts to ultraviolet light, the titanium oxide layer (53) can oxidatively decompose a substance on itself in response to the ultraviolet light of the electric lamp (4). Therefore, it is possible to sterilize the inside of the low light signboard device and exhibit antifouling properties so as not to stain the inside of the device.

The reflection sheet (5) thus configured
Is disposed in the lamp housing case (3) in a state of being bent in a groove shape. The reflection sheet (5) is pressed by a wire (18) provided so as to cross the sheet (5), whereby the reflection sheet (5) is bent into a desired shape. Although the bent shape is not particularly limited, for example, as shown in FIG. 1, four places are bent by four wires (18), whereby the flat bottom (19) and the middle part are bent. And a side wall (20). The bottom (19) is located behind the lamp (4) and the side wall (20) is located on the side of the lamp (4).

The front edge portion of the reflection sheet (5), that is, the tip portion (21) of the side wall portion (20) is located at the lamp housing case (3).
Tension fixing means (2) provided near the opening edge (22) of the
3) is pulled towards the opening edge (22).
Thereby, it is possible to prevent the entire reflecting sheet (5) from being loosened. The configuration of the tension fixing means (23) is not particularly limited. For example, as shown in FIG. 2, a tension coil spring (24) (hereinafter, referred to as a coil spring (24))
And a spring fixing member (25). As shown in FIG. 6, the spring fixing member (25) has a holding portion (26) having a U-shaped cross section and a spring locking portion (27) for locking one end of the coil spring (24). The upper end of the side plate (14) (see FIG. 2) of the lamp housing case (3) can be sandwiched by the sandwiching portion (26). An eyelet (28) (see FIG. 2) is provided at the end (21) of the reflection sheet (5), and the other end of the coil spring (24) is locked to the eyelet (28). The provision of the eyelet (28) can prevent the tip (21) of the reflection sheet (5) from being broken by the tensile force of the coil spring (24). Further, by providing the stopper (28) at the portion where the reinforcing tape (60) (see FIG. 24) is adhered, the tensile strength of the reflection sheet (5) can be more reliably increased.

Both ends of the wire (18) are fixed to the inner surface of the side plate (14) of the lamp housing case (3). The fixing method is not particularly limited. For example, the fixing can be performed using the magnetic force of a magnet. FIG. 7 is a view showing an example of a wire fixing member (30) having a magnet (29). The wire fixing member (30) includes a rectangular parallelepiped magnet (29) and a cover material (3) that covers the upper surface and two side surfaces of the magnet (29).
1) and a substantially L-shaped wire support portion (32) fixed on the cover material (31). Magnet (2
9), the cover material (31), and the wire support portion (32)
It is integrated by the screw (33) and the nut (34). The through-hole (3) is provided at the rising portion of the wire support portion (32).
5) is formed, and the wire (1) is inserted into the through hole (35).
8) is locked at one end. One end of the wire (18)
After being inserted into the through-hole (35), it is locked in the through-hole (35) by being flattened or bent.

Next, a method of assembling the low light signboard device will be described. This low light signboard device may be manufactured by renewing an existing internally illuminated signboard device, or may be newly manufactured. First, the case of renewal production will be described. First, the display board (2) is removed, and then the existing light (not shown) is removed. Usually, the existing lamps are fluorescent lamps and many lamps are arranged, but all of these lamps are removed. The existing light holder (not shown) may be removed, but may be left as it is.

Next, the lamp holder (6) of the present invention is placed in the lamp housing case (3). At this time, the holder supporting member (7) shown in FIG. 3 or the holder supporting member (7) shown in FIG. 4 may be used, but the holder supporting member (7) shown in FIG. The holder (6) is attached to the back plate (1) of the lamp housing case (3).
1) Since it can be provided at a position far away from (see FIG. 1), it can be suitably used when the existing lamp holder is left.

Next, the wire (18) is attached to the electric light housing case (3). At this time, the wire fixing member (30)
The magnet (29) of the rear panel (1)
Fix magnetic force to 1). A plurality of wires (18) are usually used, and their positions are not particularly limited.
In the example shown in (4), four wires (18) are provided in parallel with the longitudinal direction of the lamp (4), and two wires (18) are provided on both sides of the lamp (4). Then, on each side of the lamp (4), one wire (18) is provided near the lamp (4) and slightly behind the lamp (4), and the other wire (18) is located near the lamp (4). ) Is provided slightly forward of the electric light (4). Position adjustment of the front and rear of the wire (18) can be adjusted by the height of the wire support (32) in the wire fixing member (30).

Next, one end (2) of the reflection sheet (5)
1) is provided with a stop (28), and a spring fixing member (2) is provided on the upper end of the side plate (14) of the lamp housing case (3).
5) The holding portion (26) is fixed. Then, the other end of the coil spring (24) is engaged with the fitting (28). In this state, the reflection sheet (5) is sunk under each wire (18), and the opposite end of the reflection sheet (5) is placed near the upper end of the side plate (14) on the opposite side of the lamp housing case (3). Position. At this time, if the reflection sheet (5) is too long and becomes loose, it is cut to an appropriate length. A stop (28) is provided at the tip (21), and a holding portion (26) of a spring fixing member (25) is fixed to the upper end of the side plate (14) on the opposite side of the lamp housing case (3). I do. afterwards,
