Our goal is to provide the following.

Illumination devices using optical fibers can illuminate various designs, patterns, etc. by guiding the light from the light source through the optical fibers, so the thickness of the optical fibers used for each part of the design and pattern It is possible to arbitrarily change the brightness of the illumination in each part by selecting different ones or using ones of the same thickness, or to make the whole part uniform in brightness. It has many advantages such as being able to reduce power consumption by using a very small number of light sources compared to the number of places that need to be used, and making it easy to maintain and inspect the light sources. It is being developed.

However, this type of conventional lighting device is a display structure consisting of a light source device and an optical fiber part as a pair, and is suitable for display on a counter, wall-mounted display, or floor-standing display installation indoors or outdoors. Currently, there are many relatively small ones such as.

Conventionally, when installing a lighting device that has a lighting effect over a wide area, such as decorative lighting for the entire interior wall surface, it is normal to perform on-site construction such as wiring and arranging optical fibers, and installing light source devices, which reduces the construction time. However, due to the high construction costs and restrictions on the installation location, such as the need to install the light source equipment in a way that allows for inspection and repair, it is difficult to install lighting equipment using optical fibers over large areas of walls and ceilings. It was practically impossible to install it easily.

The present invention was developed in view of these circumstances, and its gist is a panel 1 having a predetermined shape and a pattern displayed on its surface, and a light source device fixed to the back of this panel 1. 2 and an optical fiber bundle 3 whose proximal end 31 is converged and whose distal end 32 is ubiquitously expanded.
The proximal end 31 of the light source device 2 fixed to the panel 1 faces the vicinity of the light source 21, and the mounting end 32 is inserted from the back side of the panel 1 to attach it, and the panel corresponds to the vicinity of the mounting position of the light source device 2. A lighting device for a wall or ceiling surface, characterized in that a repair/decoration cover 4 is attached to one surface to form a panel unit (A), and a plurality of panel units (A) are stretched on the wall or ceiling. It is in.

The lighting device of the present invention allows the lighting device to be easily installed over a wide area, making it extremely easy to inspect and repair the light source device, and further enhancing the lighting decoration effect of the entire room. Ta.

The present invention will be described in detail below with reference to the drawings of embodiments.

FIG. 1 is a front view of a wall illumination device in which a plurality of panel units A of the present invention are installed on an indoor wall, and the entire wall is decorated with a constellation pattern.

In this figure, the lighting device of the present invention is not installed on the ceiling B, but it is of course possible to install the lighting device as shown in this figure over the entire ceiling and surrounding walls.

Furthermore, the overall pattern can be made into a pattern other than constellations, making it suitable for decorative illumination using optical fibers.

According to the embodiment of this pattern, the light of the optical fiber is illuminated from the star part of the constellation at various brightnesses, giving a decorative lighting effect that makes you feel as if you are looking up at a sky full of stars while staying indoors. I can do it.

Figures 2, 3, and 4 are perspective views from the front showing typical examples of the shape of a panel unit displaying a constellation pattern, and Figure 5 is a perspective view from the back showing the internal structure of the panel unit. It is a diagram.

Figure 2 shows a flat rectangular panel unit, and Figure 3 shows a flat square panel unit.By combining and stretching a plurality of panel units 1-A in Figures 2 and 3, you can create a wall or ceiling surface. Can be used as a lighting device.

Figure 4 shows a curved panel unit, and panel unit A with this shape is designed to connect lighting device planes with different dimensions so that the lighting effect is not diminished between a wall surface and a ceiling surface, and between a wall surface and another wall surface. This is a panel unit used for connection.

Therefore, by using the panel unit shown in FIG. 4, it is possible to enhance the decorative effect of the entire room and provide a lighting effect that resembles a continuous constellation pattern throughout the room.

Panel unit (A) in FIGS. 2 to 4 is composed of a panel 1 with constellations and the Milky Way pattern on its surface, and a transparent protection plate 11 that protects the surface of the panel 1 and gives gloss to the panel surface. Ru.

Panel 1 is the main structural member of panel unit A, and is usually made of metal products, synthetic resin products, wood products including plywood, lightweight inorganic material products, paper products, etc. that are used to construct the panel. Any material can be used.

Further, as the transparent protection plate, a transparent or translucent synthetic resin plate, a glass plate, or the like can be used.

Note that 4 in the figure is a repair and decoration lid attached to the surface of the panel 1.

FIG. 5 is a perspective view showing the internal structure of panel unit A.

By attaching a reinforcing frame 12 that also serves as a support frame for attaching the light source device 2 to the inside of the panel 1, a lightweight and strong panel can be obtained.

By using this reinforcing frame 12, it is possible to attach the light source device 2 to any required location on the back surface of the panel.

The optical fiber 3 with its proximal end 31 focused is fixed to a position near the light source 21 of the light source device 2, and its end 32 is aligned with the dotted position of stars in the constellation pattern on the surface of the panel 1. 1
It is fitted and attached from the back side of the panel 1, and positioned so that the light emitted from the end face of the upper end side 32 of the optical fiber can be seen like the light of a star in the night sky.

Although the optical fiber used is not particularly limited, it is preferable to use a so-called plastic optical fiber whose core is made of polymethyl methacrylate and whose sheath is made of a fluorine-containing resin or the like.

FIG. 6 is a perspective view and a partial sectional view showing the configuration of the light source device and the proximal end side and the installed end side of the optical fiber.

The light source device 2 is housed in a light source box 24 that also serves as a light shield and protects the main body of the light source device, and the main components are the light source 21. This is a transparent color plate 22 and a motor 23 that rotationally drives the color plate.

The light from the light source lamp 21 passes through a color plate and is colored to the color that is colored on the color plate, and then the base end of the optical fiber 3 is fixed at a position near the light source 21 so that the light from the light source 21 can be efficiently collected. The inside of the optical fiber is guided from the end face of the fiber bundle on the side 31 to the end side 32, and the light is emitted from the end face on the end side 32, thereby providing an illumination effect.

Further, the color of the light emitted from the end face of the optical fiber 3 and the end side 32 can be colored into any desired color by rotating the color plate 22 colored in various patterns.

As the light source 21, an ordinary tungsten filament incandescent lamp, fluorescent lamp, halogen lamp, etc. can be used as appropriate.

The color plate 22 may be a transparent glass plate or synthetic resin plate coated with or printed with various transparent colored paints in any pattern, or a transparent plate coated with or printed with transparent colored paints. A color plate can also be made by gluing the film onto a transparent substrate.

The color plate 22 is usually shaped like a disk as shown in FIG. 6, but an endless belt-shaped color filter can also be used.

The motor 23 is preferably lightweight and compact as long as it can drive the color plate or color filter.

In this way, by constantly changing the color of the light emitted from the end face of the optical fiber 3 end 32 through the color plate,
The lighting effect seen from the surface of the panel 1 can be dynamically changed such as a color change and a change in brightness due to a change in color tone, thereby enhancing the decorative effect of the entire lighting device.

The proximal end 31 of the optical fibers focuses the required number of optical fibers within a range that can uniformly employ the light from the light source 21, aligns the fiber end faces, and fixes them at a position near the lamp.

The end side 32 of the optical fiber is attached to the panel 1 as shown in the figure.
The optical fiber end face is fixed to the panel 1 so that the end face of the optical fiber is located in close proximity to the back surface of the panel surface transparent protection plate 11 so that the light emitted from the end face on the installation end side can be directly viewed.

FIG. 7 is a panel sectional view showing the main parts of the mounting of the light source position 2.

The light source device 2 is fixed to the panel reinforcing frame 12 with screws 25 through the wall of the light source box 24.

In addition, as shown in this figure, the light source device 2 is mounted on the panel 1 so that repairs, inspections, lamp replacements, etc. of the light source device can be easily performed from the front of the lighting device when the lighting device is installed on a wall or the like. A hole 5 of an appropriate size is provided near the position, and a dome-shaped lid 4 is fixed to the hole 5 on the surface of the panel 1 with a washer 41 and screws 42.

In this example, the lid 4 has a shape resembling a celestial body, for example, so as to match the pattern on the surface of the panel 1, and can be appropriately colored to give a unique decorative effect.

Of course, it is also possible to install a light source near the back of the lid 4 for illumination.

Conventionally, for large lighting devices such as this type, when inspecting or repairing the light source device, it is necessary for workers to remove the entire lighting device or work behind the wall or ceiling surface. The problem was that it required a lot of time and effort.

In the present invention, since the wall or ceiling surface is made up of a plurality of panel units, it is possible to work by removing only the panel unit where the problem occurred.

In particular, in the present invention, one or more lids 4 are attached to the surface of the panel 1 corresponding to the light source device 2, as shown in FIG. The replacement work can be easily performed, and the maintenance time for the light source can be greatly shortened.

Since the present invention has the configuration as detailed above, the configuration of the lighting device panel unit is rational, and the lighting device can be easily installed over a wide area.
Inspection and repair of the light source device after installation is extremely easy, and the entire room can be effectively illuminated.
Furthermore, there is an advantage that this type of lighting device for walls and ceilings can be provided easily and inexpensively.
