Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power-saving display device suitable for use as, for example, a signboard or the like and displaying an image with good power.

[0002]

2. Description of the Related Art At present, many stores such as convenience stores are open even at night, and display devices are used as sign lights in such stores. An example of a display device that is such a sign light will be described below with reference to FIG. FIG. 11 is a vertical sectional side view of the display device.

[0003] The display device 101 comprises a main body frame 10.
2, a display unit 103, a plurality of linear light sources 104, and the like. The main body frame 102 is formed in a box shape with an open front surface, and the display means 10
3 is attached. The display means 103 includes a light-transmitting main body panel 105 and a light-transmitting picture part 1
06, and the part 106 of the picture portion is adhered to the surface of the main body panel 105. Linear light source 104
Is a straight tube type fluorescent lamp here, and the main body frame 10
A plurality of devices are arranged in parallel inside the device 2.

In the display device 101 having such a structure, for example, the picture portion of the display means 103 is formed as a mark of a store. When the linear light source 104 is turned on, the light passes through the display means 103 from the back side to the front side, so that the display means 103 emits light, so that the shop can be advertised well even at night. In particular, since the store mark is formed by the component 106 and the component 106 emits light in each color with the main body panel 105 as the background, the store mark can be advertised favorably.

In a convenience store or the like, not only a main display device having a store mark formed thereon, but also peripheral display devices connected to both sides of the main display device so as to be generally installed at the entrance of the store or above the window. In some cases, a band-shaped display device is formed. Thereby, the presence of the entire store is appealed, and the store name is displayed on the main display device which is a part of the display device. In this case, the main display device is formed as a single unit, but as the peripheral display device, only the display means of the main display device is changed and other parts are shared to increase productivity. . Therefore, in order to lengthen the entire display in a strip shape, a plurality of peripheral display devices are connected to one main display device.

[0006]

In the display device 101 as described above, since the display means 103 emits light, it is possible to advertise well even at night.

However, in such a display device 101,
Although the large display means 103 is used to improve the advertising effect, a large number of linear light sources 104 are required to cause the large display means 103 to emit light. For this reason, the above-described display device 101 consumes large power,
The running cost of replacing the linear light source 104, which is a consumable item, is large, and the work of replacing the linear light source 104 is complicated. Further, there is a method of weakening the diffusivity of the milky white acrylic plate used for the display panel. However, this method has a problem that luminance unevenness becomes large and visibility becomes poor.

In the display device 101 as described above,
The brightness of the display means 103 tends to be non-uniform in accordance with the arrangement of the linear light sources 104, and it is difficult to make the display means 103 emit light uniformly. In order to solve this, it can be assumed that the linear light sources 104 are arranged at high density, but this is not preferable because the running cost of the display device 101 increases. The linear light source 104 and the display unit 10
Although it is conceivable to increase the interval with 3, the display device 101 is undesirably increased in size.

On the other hand, when the entire display device is formed in a belt shape, as described above, the main display device and the peripheral display device are manufactured with the same components and the same structure only by changing the display plate. However, there is a problem that the main display device is hardly conspicuous and the store name is not clear.

An object of the present invention is to provide a display device in which the display portion of the main display device is clear, and even if the number of linear light sources is small, there is no luminance unevenness and the picture portion can be illuminated satisfactorily. With the goal.

[0026]

FIG. 1 shows a first embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 is a front view of a display device, FIG. 2A is a front view of a main display device, and FIG.
3A is a front view of the peripheral display device, FIG. 3B is a longitudinal side view of the peripheral display device, and FIG. 4 is a light guide unit, a linear light source, and a lamp. FIG. 5 is an exploded perspective view of a portion with a socket, and FIG. 5 is a vertical sectional side view showing an optical relationship between a linear light source and a light guide. First, the one shown in FIG. 1 has five display devices 1, that is, one main display device 1a and four peripheral display devices 1b arranged in a horizontal line with the main display device 1a positioned at the center. It was done. The main display device 1a and the peripheral display device 1b differ only in the picture portion of the display means described later, and the other components are the same. Here, the above-described display device 1 includes a main body frame 2, a circuit unit 3, a linear light source 4, a light guiding unit 5, a light reflecting unit 6 including a white sheet or the like, and a light including a reflection control unit such as a white dot or the like. It comprises a control means 7 and a display means 8.

The main body frame 2 is formed in a flat box shape in the front-rear direction, and has an open front surface. The display means 8 is mounted on the front surface of the opening, and the linear light source 4 and the light guide means 5 are arranged inside the hollow. The circuit unit 3 is formed in an elongated box shape,
It is fixed inside the main body frame 2. A power supply circuit and the like are arranged in the inside, and lamp sockets 9 are protruded from both sides of the upper surface. This lamp socket 9
This is a so-called butt type, in which a pair of terminal holes 10 are located horizontally as shown in FIG.

The linear light source 4 is, for example, a straight tube type fluorescent lamp, and an opening 11 for emitting a light beam is partially formed in parallel with the longitudinal direction of the outer peripheral surface. That is, as shown in FIG. 5, the white reflector 13 and the phosphor 1 are provided on the inner surface of the linear light source 4.
3 'is applied, but this application is partially omitted, so that the colorless and transparent opening 11 is formed. As shown in FIG. 4, the linear light source 4 is formed so that the opening 11 is located above or below with the pair of terminals 12 being horizontally located. The opening 11 is held in a state where the linear light source 4 is held.
Is located above.

The light guide means 5 is, for example, a transparent acrylic panel, and is fixed inside the main body frame 2 so as to face the linear light source 4 held by the lamp socket 9 from above. In this state, the lower side surface 1 of the light guide means 5
The light guide 4 faces the opening 11 of the linear light source 4, the front surface 15 of the light guide 5 faces the display 8 from behind, and the back 16 of the light guide 5 faces the inner surface of the main body frame 2. The light reflecting means 6 is, for example, a white vinyl sheet, and is integrally joined to the entire back surface 16 of the light guiding means 5.

The reflection control means 7 acting as the light control means has a higher density as the distance from the light-incident side surface 14 of the light guide means 5 increases, and becomes maximum at a position 70 to 90% of the light guide length. It is desirable to do. Accordingly, even when the linear light source 4 is provided at the side portion, it is possible to display with uniform luminance over the entire surface of the display unit 8. The reflection control means 7 may be any means as long as the light guided inside the light guide means 5 is irregularly reflected on the back surface and emitted from the front surface. For example, the light is printed on the back surface 16 of the light guide means 5. It is formed as a white or silver-colored paint, a portion where the back surface 16 of the light guide means 5 is sandblasted, or the like. The reflection control means 7 is arranged on the entire surface of the main display device 1a, and is formed in substantially the same shape as the picture portion 17 of the display means 8 in the peripheral display device 1b.
It is arranged so that it may be located on the back side of.

The display means 8 has a translucent main body panel 18 and a translucent picture part 17 part 19, and this part 19 is integrally joined to the surface of the main body panel 18. Thus, the picture portion 17 is formed. For example, the main body panel 18 is a transparent acrylic panel body, and the component 19 is an acrylic panel body colored in each color. The part 19 is formed in the shape of a store mark here, and is located on the front side of the light control means having the same shape.

The front surface of the light guide means 5 and the back surface of the picture portion 17 are opposed to each other with a predetermined space therebetween. For example, this space is about 40 (mm). The total width of the display means 8 is about 8
00 (mm), the width of the picture part 17 is about 470 (mm), and the total length of the linear light source 4 is about 540 (mm). It is manufactured as a structure formed with. On the surfaces of the display means 8, the light guide means 5, and the light control means, for example, a photocatalytic film of TiO ₂ (both not shown) is formed via a thin film layer of SiO ₂ .

The operation of this embodiment will be described. The display device 1 of the present embodiment is a combination of the main display device 1a and the surrounding display device 1b, and is installed, for example, as a signboard light above the entrance of a store as shown in FIG. When the linear light source 4 is turned on, the light beam enters the lower side surface 14 of the light guide 5 and is totally reflected in the light guide 5 by the front surface 15 and the back surface 16.

However, at the position where the reflection control means 7 is formed on the back surface 16 of the light guide means 5, the light beam is irregularly reflected from the inside of the light guide means 5 by the reflection control means 7 and is emitted from the front surface 15. Then, some of the light beams pass through the reflection control means 7 and are reflected by the light reflection means 6. Therefore, in the main display device 1a, a large amount of light passes through the display means 8, and the brightness is high over the entire surface. On the other hand, in the peripheral display device 1b, although the light amount toward the picture portion 17 is as large as that of the main display device 1a, the light amount to the other background portion is low, and thus the overall brightness is reduced. Is low. Therefore, the main display device 1a and the peripheral display device 1
b, there is a contrast of the luminance, and if the whole is viewed, the main display device 1a and the peripheral display device 1b as a whole emphasize the location and existence of the store, and then the main display device 1a High visibility makes it easy to confirm the store name and the like.

The light beam guided into the light guide means 5 is actually emitted from the front surface 15 and the back surface 16 where the reflection control means 7 is not formed, though it is weak. However, the light beam emitted from the back surface 16 of the light guide means 5 is reflected by the light reflection means 6 and is emitted from the surface of the light guide means 5. The weak light emitted from the back surface 16 where the reflection control means 7 is not formed is transmitted through the main body panel 18 and emitted from the surface of the display means 8.

In the display device 1 of the present embodiment, light rays are emitted from the surface of the display means 8 as described above, so that the display means 8 emits light, and can function as a signboard light. At this time, in the main display device 1a, the picture portion 17 of the store mark emits light in each color. Further, in the surrounding display device 1b, for example, the picture panel portion 17 formed in a horizontal stripe emits light, and the
The portion 8 emits white light, but the pattern portion 17 emits light with higher luminance than the background portion. Therefore, the picture portion 17 does not look dark like a shadow picture, and advertisement can be performed more favorably.

Further, the reflection control means 7 in the peripheral display device 1b is formed in the same shape as the picture portion 17, but the front surface of the reflection control means 7 and the back surface of the picture portion 17 face each other at a predetermined interval. Therefore, the light beam emitted from the surface of the reflection control means 7 spreads slightly and irradiates the peripheral portion of the picture portion 17. That is, since the picture part 17 emits light together with the peripheral part, the picture part 17 can be raised in a three-dimensional manner.

Furthermore, in order to make the store mark look three-dimensional, it is not necessary to actually form the picture part 17 in a three-dimensional structure, and the display means 8 may be flat. For this reason, the structure of the display means 8 is simple, the productivity of the display device 1 is good, and it is possible to prevent dirt from attaching to the unevenness of the display means 8.

In particular, in the display device 1 of the present embodiment, since the photocatalyst film for oxidizing and reducing the organic substance irradiated with ultraviolet rays is formed on the surface of the display means 8 and the like, the display means 8 is irradiated with sunlight. Then, the organic dirt is automatically purified. Further, since the photocatalyst film is formed via the SiO ₂ thin film layer, peeling due to deterioration with time hardly occurs, and deterioration of the display means 8 due to ultraviolet rays is reduced.
That is, since the display means 8 is hardly stained and hardly faded, the mark of the store can be maintained beautifully.

Further, in the display device 1 of the present embodiment,
Even if a large-sized display means 8 is used to improve the advertising effect, only one linear light source 4 is sufficient, so that the power consumption is small and the running cost due to replacement of the consumable linear light source 4 is small. The labor for replacing the linear light source 4 is also reduced. In addition, since the picture portion 17 of the display means 8 mainly emits light by using the reflection control means 7 as described above, if the total length of the linear light source 4 is larger than the width of the picture portion 17, the display means 8 may be used.
May be smaller than the full width of In other words, the large display means 8 having a good advertising effect can be emitted by one short linear light source 4, and a commercially available general fluorescent lamp can be used as the linear light source 4.

Further, in the display device 1 of the present embodiment,
Since the linear light source 4 is arranged at the bottom of the main body frame 2, the linear light source 4 can be easily replaced even if the display device 1 is installed above a store as a signboard light. Further, as described above, since the light from one linear light source 4 is applied to the entire area of the display means 8 by the light guide means 5, the display means 8 can emit light uniformly. In particular, since the light reflecting means 6 is arranged to face almost the entire back surface 16 of the light guiding means 5, light rays emitted from the back surface 16 of the light guiding means 5 are also reflected to the front side, and the entire area of the display means 8 is made uniform. It is possible to emit light satisfactorily.

In the display device 1 according to the present embodiment, since the opening 11 is formed in the linear light source 4, substantially all of the light emitted from the linear light source 4 is guided without the need for a reflector or a lamp cover. The light is satisfactorily emitted to the side surface 14 of the light means 5.
In addition, since the lamp socket 9 holding the linear light source 4 is a butt type, the opening 11 of the linear light source 4 is
Can be accurately opposed to the side surface 14.

However, it is also possible to add a reflector and a lamp cover to the above-mentioned structure, and to converge the light emitted from the linear light source 4 to the side surface 14 of the light guide 5 more effectively. When the reflector and the lamp cover are provided in this manner, since it is not necessary to provide an opening in the linear light source, a commercially available general fluorescent lamp can be used as the linear light source,
Further, running costs can be reduced.

In the display device 1 described above, the display means 8
In order to make the pattern portion 17 emit light together with the peripheral portion, the back surface and the front surface 15 of the component 19 of the pattern portion 17 are separated from each other. It is also possible to form a large shape. If it is desired not to emit light in the peripheral portion while emitting light in the picture portion 17 of the display means 8, the reflection control means 7 is formed in a shape slightly smaller than the picture portion 17 of the display means 8, and What is necessary is just to bring the back surface of the component 19 of 17 and the surface of the reflection control means 7 close to each other.

In the display device 1 described above, the picture portion 17
Since the components 19 are joined to the surface of the main body panel 18 to form the display means 8, the double-sided tape for fixing the components 19 of each color is not seen through the colorless and transparent main body panel 18. However, if this does not cause a problem, it is possible to join the component 19 to the back surface of the main body panel 18, and in this case, the surface of the main body panel 18 becomes completely flat, so that adhesion of dirt can be prevented well. It is possible to satisfactorily prevent the parts 19 from falling off due to the deterioration with time of the bonding means. Further, it is also possible to disperse and join the above-described components 19 on the front surface and the back surface of the main body panel 18 to form the picture portion 17 three-dimensionally.

Further, in the above-described display device 1, a structure in which one display means 8 is located on only one side is illustrated assuming a signboard light to be embedded in a wall surface. It is also possible to form a display device (not shown) of the display means.

In such a display device, for example, a pair of light guide means 5 provided with respective reflection control means 7 are integrally joined together on the back surfaces 16, and both of the integrated pair of light guide means 5 are provided. It can be formed by making a pair of display means 8 individually face the surface 15. In the display device having such a structure, the pair of display means 8 located on both sides emit light, respectively, so that it can be used, for example, as a signboard lamp erected on the roadside. Even if the pair of display means 8 emits light in this way, only one linear light source 4 and one light reflecting means 6 are required.
The power consumption is small and the running cost is low.

The light reflection means 6 is omitted, and the reflection control means 7 is provided on both the front surface 15 and the back surface 16 of one light guide means 5.
And a pair of display means 8 can be individually opposed to each other. In this case, when the main body panel 18 of the display means 8 is colorless and transparent, the picture portion 17 on the back side can be seen, so that the main body panel 18 is preferably white.
Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 6 is a partial vertical side view showing the relationship between the display means and the light guide means. In the present embodiment, the density of the white dots that diffusely reflect light from the reflection control means 7 is changed, and the density of the position of the display means 8 facing the picture part 17 is increased, and the picture part 17 does not exist. The density of the portion, that is, the position facing the background portion is roughly formed. Therefore, since the amount of light that is irregularly reflected by the reflection control means 7 is present, the portion of the picture portion 17 is emphasized, and when the picture portion 17 is a shop name, an advertisement in which the portion is emphasized can be made.

A third embodiment of the present invention will be described with reference to FIG. FIG. 7 is a partial longitudinal side view showing a relationship between the linear light source 4 and the light guide means 5. In the present embodiment, a reflecting mirror 31 is provided around a linear light source 4. The reflecting mirror 31 is made of, for example, aluminum or the like, and has a high reflectance on the reflecting surface. Then, the light emitted from the linear light source 4 is reflected toward the lower side surface 14 of the light guide means 5, so that the light amount can be effectively used.

FIGS. 8 and 9 show a fourth embodiment of the present invention.
It will be described based on. 8A is a front view of the main display device, FIG. 8B is a vertical side view of the main display device, and FIG. 9 is a vertical side view showing the relationship between the light guide 5 and the linear light source 4. . In the present embodiment, the light guide means 5 is separated at the center part, the light reflection means 6 is provided on the end face 41 and joined together, and the linear light source 4 is opposed to each side face 14. Is arranged. Therefore, since the linear light sources 4 are present above and below, and the light of the linear light sources 4 is guided by the separated light guiding means 5, the brightness of the display means 8 can be improved with little loss. In addition, because of the sidelight system, the whole is thin and workability is good.

Next, a fifth embodiment of the present invention will be described with reference to FIG.
Description will be made based on 0. FIG. 10A is a front view of the main display device, and FIG. 8B is a vertical sectional side view of the main display device. In the present embodiment, the picture portion 17 of the display means 8 is formed on the light guide means 5 side surface, that is, on the inner surface of the display means 8. Therefore, the picture portion 1 formed by bonding or the like
Since the display 7 is provided on the inner surface of the display unit 8, the display unit 8 is not exposed to the outside, the durability and weather resistance of the display unit 8 are improved, and the display unit 8 can be used for a long time. Further, since the outer surface of the display means 8 is a flat surface, it is hardly soiled, the cleaning is easy, and the maintenance cost can be reduced.
