Description

[Detailed description of the invention] <Industrial application field> The invention relates to a display device, and more specifically, a light source consisting of an ultraviolet-emitting fluorescent lamp is directed at a display line containing a fluorescent substance to cause it to emit light. The present invention relates to a display device.

<Prior art> As a display device that emits psychedelic-like signs in place of neon signs, a method has long been known in which a fluorescent lamp that emits ultraviolet light is used as the light source and a fluorescent material is contained in the display line. .

However, in the conventional display device using this method, as shown in FIGS. 6 and 7, light sources A, A, B, and B are located at both ends, and the display lines C, C, and C are reflected from the upper side. was reflected from the side surface, and display lines H and E were transmitted from the bottom surface.

In order to highlight the luminescence of display lines C, D, and H, the strong light of light sources A and B is avoided so that they cannot be seen directly, and the light sources are placed far away at both ends of the viewer's side, and mainly use reflected light. The principle is

However, as a result, when the area of the display device becomes large, the luminance of the emitted light decreases.

<Problems to be Solved by the Invention> The purpose of the display device of the present invention is to provide a display device that does not reduce the luminance of emitted light and can be applied to large areas.

<Means for Solving the Problems> The present invention solves the above problems by providing a display device having the following features.

The present invention includes a light source and a display panel located in front of the light source.

The light source consists of a fluorescent lamp that emits ultraviolet light.

On the other hand, the display board is made of a material that can transmit light, has a diffused reflection part that diffusely reflects light on at least one side, and has a display line. The display line is arranged on one side of the display panel, and the display panel includes a shielding layer forming a portion that shields light, and a light-emitting member made of a tubular body or the like containing a fluorescent substance. Further, the light-emitting member is arranged on the side of the light-transmitting part of the display board defined by the shielding layer.

In addition, in the present invention, "containing a fluorescent substance" means that it is made of a phosphor material in a broad sense in which a fluorescent substance is coated and mixed, and a "light-emitting member" may also include numbers, letters, etc. However, it mainly consists of long lines in the form of tubes, square pipes, and strings, and these lines are used to display the outline of the pattern and are used in place of neon signs. ” <Operation> The present invention can prevent glare from the light source using the diffused reflection section.

Thereby, the display line can be provided in front of the light source, and the brightness of the display line can be increased.

On the other hand, since the display line is formed by the light-emitting member and the shielding layer, the shielding layer can shield light from areas other than the light-emitting member.

Thereby, the light emitting member can be clearly displayed.

<Example> Hereinafter, an example of the present invention will be specifically described based on the drawings.

The attached FIGS. 1 to 5 show an embodiment of the display device of the present invention. As shown in FIG. 1, the main components of the display device 1 of the present invention include a frame 2 made of aluminum or the like, a back surface (not shown) of the case made of an opaque acrylic plate, etc. has a non-reflective black finish, and is composed of a surface 3 of a case made of a transparent diffused reflection plate, a light source 4, a light emitting member 5, and a shielding layer 6.

FIG. 2 is a sectional view showing the main part, 13
shows a transparent diffused reflection plate made of a plate shaped like crushed ice.

This transparent diffused reflection plate 13 is not opaque like frosted glass, but is made of a transparent plate.
The surface is smooth, but the back surface has irregularities similar to crushed ice, making it difficult to see the back surface from the front surface.It is a board material that is used in bathrooms, etc., and is made of glass, acrylic, etc. is used. On the front side, light emitting members 15a, 15a, 15b are provided.
are glued at three locations, top, middle, and bottom, and the transparent diffused reflection plate 13 is provided on the back side when viewed from the light emitting members 15a, 15a, and 15b. The upper and lower light-emitting members 15a, 15a are blue, and the middle light-emitting member 15b is orange, and long lengths made of PVC pipes are bent to form letters and patterns. (See Figure 1). Reference numeral 14 denotes a light source consisting of a fluorescent lamp that emits ultraviolet rays, and is provided on the back surface of the light emitting members 15a, 15a, 15b so that the light is transmitted through the light source.

In this implementation, this light source 14 is generally called a black light, and is a fluorescent lamp made of black ultraviolet-transmitting glass that blocks visible light. For example, it emits ultraviolet light with a wavelength of about 360 mm. , they use fluorescent lights that emit mostly invisible light.

Further, on the surface of the transparent diffused reflection that does not require seeing through the light emitting members 15a, 15a, 15b, shielding layers 16, 1 covered with an opaque black vinyl sheet are provided.
It is equipped with 6, 16, 16.

The display device 1 of the present invention has the shielding layers 16, 1
6, 16, 16 and the light emitting members 15a, 15a,
15b to form a display line.

By doing this, the shielding layers 16, 16, 1
6 and 16 block light from parts other than the light emitting members 15a, 15a, 15b, and the light emitting members 15a, 15a,
Only 15b can be clearly seen.

In addition, the blue light emitting members 15a, 15a exhibit luminance comparable to that of the orange light emitting member 15b, and the three-dimensional effect of the pipe gives off an intense psychedelic mood, and the shielding layers 16, 16, 16, Coupled with the effect of light source 16, the position and glare of light source 14 became less noticeable.

3 to 5 show other embodiments.

23 in FIG. 3 is also a transparent diffused reflection plate, 2
5a and 25a are blue, and 25b is an orange light-emitting member consisting of a tube with a semicircular cross section, but the inner diameter of the tube is coated with fluorescent paints F, F', and F' to improve the luminescence.
F is coated. 24 indicates a light source.
Further, the surface of the transparent diffused reflection plate 23 is coated with opaque black screen printing to cover the shielding layers 26 and 2.
6,26 are formed. As a result, strong luminance could be emitted from the light emitting members 25a, 25b, and 25a.

Reference numeral 35 in FIG. 3 similarly indicates a transparent diffused reflection plate, and the light emitting members 35a and 3 are made of blue square pipes.
5a is adhered to the surface of the transparent diffused reflection plate 33, and a light emitting member 35b made of an orange square pipe is adhered to the back surface of the transparent diffused reflection plate 33. 34 indicates a light source;
36, 36, 36, 36 are shielding layers in which the surface of the transparent diffused reflection plate 33 is coated with translucent sky blue screen printing. The translucent sky blue color conveys a different mood from that of black color, and the blue light emitting members 35a, 35a emit luminance that is higher than the orange light emitting member 35b.

In addition, 43 in FIG. 5 is the same transparent diffused reflection plate, 45a is a light emitting member made of a blue flat plate attached to the surface, and 45b is the back side with a space between it and the transparent diffused reflection plate 45 to form and solidify a shaped pattern. The light-emitting member 45c shown here is a light-emitting member formed by applying fluorescent paint directly to the surface of the transparent diffused reflection plate 43. 44 is a light source, and 46, 46, 46, 46 are covered with a shielding layer made of a translucent yellow vinyl sheet. The yellow back gives off a bright atmosphere, and the light-emitting members 45a, 45b, 45a all emit as splendid luminance as the light source 44.
It didn't bother any of the three.

In the case of the display device of the present invention, the luminescent member can be directly coated with fluorescent paint as long as it contains a fluorescent substance. If you do this, the three-dimensional tube will be doubled.

However, if the light sources made of black lights are arranged at the peripheral edge as in the past, it is not possible to increase the area of the notice board where the display lines are placed.
It could not be applied to a relatively small area. For example, when the distance between the light source and the display line is 500 mm or more, the luminance of the light emitted decreases to such an extent that it is almost difficult to detect the received light, making it impossible to put it into practical use.

Of course, it is possible to move the light source a certain distance away and emit light from a vertical surface, but increasing the thickness of the casing would go against the demands of the times. There is also a method of increasing the number of light sources, but this is not an efficient method.

In order to resolve these contradictions, this invention
As a result of transmitting the light source from behind the display line through a transparent diffused reflection plate, the light source does not feel the position or glare even when viewed directly. It provided comparable light and enabled larger area display devices.

For the transparent diffused reflection plate used in this invention, acrylic plates or glass plates made of crushed ice-shaped plates are particularly suitable. Pine-shaped, wavy, and crystal-cut shapes can also be used, but rough snow-shaped ones are suitable. is preferred.
Therefore, milky translucent or frosted glass can be used regardless of its quality.

The light-emitting member may be placed on the back or front of the transparent diffused reflection plate, in close contact with each other or with a distance between them, and the light source may also be placed in close contact with or close to the back side of the transparent diffused reflection plate.

<Effects of the Invention> As described above in the embodiments, the display device of the present invention can prevent glare from the light source by providing the diffused reflection section.

Thereby, the display line can be provided in front of the light source, and the brightness of the display line can be increased compared to the conventional display line.

Furthermore, the shielding layer allows light to pass through only the light emitting member.

This allows the light emitting member to appear more clearly.

Therefore, the present invention can provide a display device that can vividly illuminate display lines.
