Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an internally illuminated panel device using an internally illuminated panel. More specifically, the present invention relates to an internally illuminated panel device in which a transmissive film such as a photograph of a photograph is arranged in front of an inner illuminated panel so that an image printed on the permeable film can be uniformly projected by illuminating the inner illuminated panel.

[0002]

[Prior art] The forehead with the remains displayed on the altar,
It is generally installed at the top of the altar. The altar itself is brightly illuminated by a large number of lamps, but on the forehead it is not specially illuminated, but instead relies on interior lighting.

[0003] Also, photographic panels displayed on walls and the like as interior interiors, foreheads for paintings, etc., are not illuminated by themselves, but rely on interior lighting.

As a means for solving these disadvantages, a panel device in which the forehead and the panel itself are internally illuminated can be considered. This panel device is a method for illuminating a photograph by illuminating the photograph with a fluorescent light.

[0005]

However, in this internally illuminated panel device, since a fluorescent lamp is used as a light source, the whole device becomes large, the weight becomes considerably heavy, and it is difficult to carry. Furthermore, it is difficult to uniformly illuminate the entire photograph, and the desired effect cannot be expected.

Accordingly, the present invention has solved such a conventional problem. In particular, the present invention provides an internally illuminated panel device which is small in size, light in weight and excellent in portability and can be uniformly irradiated by using an internally illuminated panel. It is a suggestion.

[0007]

In order to solve the above-mentioned problems, according to the present invention, there is provided an internally illuminated panel which uniformly emits light from a surface, a protection plate disposed on one side of the internally illuminated panel, and It is characterized by comprising a transmissive film on which the image arranged on the other side of the panel is printed, and a storage frame for storing the inner light panel, the protective plate and the transmissive film.

[0008] Since the internal illuminating panel itself emits surface light, an image printed on the transmissive film can be uniformly projected. Since only a sheet-like panel or the like is stored in the forehead used as the storage frame, it is lightweight, thin, and excellent in portability. Since it is a surface illuminant, it can uniformly illuminate the entire transmission film, so that there is no unevenness in brightness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an internally illuminated panel device according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment in which the internally illuminated panel device 10 is configured as a forehead for decorating a shadow, and FIG. 2 is an exploded perspective view thereof. As is clear from FIG. 2, the internally illuminated panel device 10 according to the present invention includes an internally illuminated panel 11 that performs surface light emission. As will be described later, as the inner illuminating panel 11, a flexible electric field light emitting sheet whose at least its front surface 15 emits light in a uniform manner, a phosphorescent sheet emitting light in a uniform manner, or the like can be used. The example in the figure is a case where a flexible electroluminescent sheet is used.

A support plate (support sheet) 12 which also serves as a reflection plate and a protection plate is provided on an adhesive sheet 17 on the back side of the inner light panel 11.
It is stuck and integrated using such as. A transmission film 18 is provided on the front side of the inner light panel 11. A shadow is printed on the transmission film 18. The transmission film 18 may be a black and white film or a color film. A well-known copying machine can be used to print the shadow on the transmission film 18.

On the front surface of the transmission film 18, a protective transparent sheet 19 for protecting the transmission film 18 is provided.
In this order, it is stored in the frame 14 as a storage frame.
Instead of a transparent sheet, a transparent film or a transparent glass can be used. For the forehead 14, a normal amount for including a picture or the like can be used, or a dedicated amount can be used.

As is well known, a flexible electroluminescent sheet 11 used as an internal light panel includes a flexible back electrode layer,
A phosphor layer superimposed on the flexible back electrode plate with a flexible insulating layer interposed therebetween and a transparent film electrode layer superimposed on the phosphor layer are laminated and united in this order. And the whole is covered with a transmission film.

A plug 16 which is an electrode end is led out to each of the back electrode layer and the film electrode layer, and the plug 16 is fitted into a socket 21 provided on the inverter (AC-AC inverter) 13 side. The inverter 13
Powered by a power supply of 00 to 115 volts,
An output voltage of hertz alternating current is obtained.

In order to project the burned-up photograph on the transmission film (posture photograph) 18, first, the power plug 20 is plugged into the outlet of the room, and the inverter 13 is projected.
Drive. A high electric field (alternating electric field) is applied from both sides of the phosphor layer of the flexible electroluminescent sheet 11 by the AC voltage obtained at this time, and the phosphor layer emits light (surface emission). Since the phosphor layer emits light, the sheet itself emits surface light uniformly. Since the transparent film 18 is provided on the front surface of the flexible electroluminescent sheet 11, the photograph is internally illuminated and the photograph is uniformly and brightly projected. Therefore, even if a remains are displayed on the uppermost part of the altar, the remains can be clearly seen from a distance.

The brightness of the shadow to be illuminated can be controlled by the number of cycles of the AC voltage, and the brightness increases as the frequency increases. Of course, the brightness can be similarly adjusted by adjusting the AC voltage value.

In the above internally illuminated panel device 10,
The flexible electroluminescent sheet 11 has a thickness of about 1 mm,
Since it is extremely light, it is thin and suitable for weight reduction. As a result, the panel device 10 is excellent in portability, and there is no possibility that the place where the remains are displayed is limited.

As the flexible electroluminescent sheet 11 used in the internally illuminated panel device 10, in the above description, the dielectric layer (insulating layer) is interposed between the electrode layer and the fluorescent layer, and the fluorescent substance is formed by alternating current. Although a structure in which a high electric field is applied to the layers has been described, a surface emitting sheet having a structure in which a high electric field is applied by a direct current to a barrier between the electrode layer and the phosphor layer may be used.

As the internal illuminating panel 11, a phosphorescent sheet may be used instead of the above-mentioned flexible electric field surface emitting sheet. The light-storing sheet is also a surface light emitter, and the light-storing sheet stores light by irradiating the entire surface with ultraviolet rays from the front side or the back side for several tens of seconds, and emits surface light with the stored light. For example, a phosphorescent sheet having a plate thickness of about 3 mm is used, and by irradiating the sheet with ultraviolet rays for 20 to 30 seconds, light emission is continued for about 3 hours. When the plate thickness is about 1 mm, light is emitted for about one hour with the same irradiation time. By irradiating ultraviolet rays for a similar time before the light emission stops, light emission continues at the same intensity again. Therefore, by irradiating ultraviolet rays regularly, light emission can be continued.

[0020] This internally illuminated panel device 10
When using the luminous sheet, simply place an ultraviolet light emitting device on the ceiling of the room where the altar is placed or on the front lower side or the back side of the altar forehead mounting table and drive it intermittently, Continuous light emission is possible. Therefore, a transparent acrylic plate or the like may be used as the protection plate 12 shown in FIG.

The luminous color of the luminous sheet varies depending on the luminous agent impregnated therein. As the phosphorescent sheet, for example, a phosphorescent sheet manufactured by Nemoto Chemical Industry Co., Ltd. can be used.

Since the internally illuminated panel device 10 is thin, light and excellent in portability, it can be applied to a photographic panel used as an interior in a room. In this case, a corresponding photographic image or the like is printed on the transmission film 18. Of course, in places where large panels are used, such as museums and wedding halls, it is preferable that the panels can be clearly recognized even from a distance. If the internal light panel device according to the present invention is used, the demand can be satisfied only by increasing the size of the internal light panel 11.

[0023]

As described above, according to the present invention, an image printed on a transmissive film is projected by using an internal light panel.

According to this, since the internally illuminated panel which emits light uniformly from the surface is used, the image printed on the transmission film can be clearly recognized even from a long distance. In addition, since this panel device can be made thin and light, and is excellent in portability, it can be used as a normal forehead without taking up space. Moreover, there is no limitation on the mounting place. Therefore, it is extremely suitable for application to a forehead for decorating a shadow, a photographic panel installed in a room or a museum, and the like.
