  As described above, a conventional shadow image device generally irradiates light on a light-shielding contrast object and projects a shadow image on a projection plane provided at right angles to the light irradiation direction. If you try to project a shadow that is extended to the projection surface by irradiating light obliquely with respect to the projection surface, the distance from the light source will diffuse and the outline of the silhouette will be lost. As a result, there was a problem that a normal shadow picture could not be obtained.

  The inventor of the present application has intensively studied a lighting device that incorporates light and shadows and has artistic characteristics. As a result, in order to emit light as long as possible vertically, a contrast image is provided on a curved surface with transparency or light transmission. As a result, the present invention has come to the present invention, and the present invention is used as a decorative lighting device for an event, or as a decorative lighting device for an office, a store, a living room, a drawing room, a bedroom, etc. It is an object of the present invention to provide a decorative lighting device (abbreviated as a decorative shadow lighting device) that projects a shadow that is used and creates a comfortable space, and a method for manufacturing a contrast pattern.

  In order to solve the above-mentioned problems, the present invention provides a contrast body that is transparent or light transmissive and has a contrast pattern on a curved surface, and irradiates light obliquely toward the contrast body.

  Further, in order to solve the above-described problems, the present invention is such that the cover includes a back plate provided to face the lower side of the shadow projection surface, and a light transmitting property provided continuously to the back plate. The light source comprises a front shade, and a back shade and a top shade having light transparency covering the front shade from above, and an opening is formed by cutting both an upper end portion of the back plate and a rear end portion of the top shade. The contrast body is covered with the cover, and the light and shadow irradiated from the light source and transmitted through the contrast body pass through the opening to form a shadow extending vertically to the shadow projection plane located behind the back plate. It is preferable that the decorative shadow illumination apparatus is characterized in that a light source and a contrast medium are arranged so as to form an image.

  In order to solve the above-mentioned problems, the present invention is preferably the above-mentioned decorative shadow illumination device, wherein the light source includes an inverted U-shaped filament. ).

  In order to solve the above-mentioned problem, the present invention is provided with either or both of a light and a black light in the cover together with the shadow device, and when the black light is provided, on the inner peripheral surface of the front shade. Preferably, the decorative shadow illumination device is characterized in that the applied fluorescent material is irradiated with black light to emit light (Claim 4).

  In order to solve the above-mentioned problems, the present invention provides a step of inputting an original picture of a picture and a scale of the original picture into a computer by an input device, and plotting the original picture at coordinates in a file. A step of reducing and deforming coordinates in a file on which the original image is plotted to a predetermined scale, a step of printing a picture on the reduced and deformed coordinates on a transparent film or a contrast medium by an output device, and transparent In the case of printing on a film, it is preferable to provide a method for producing a contrast pattern, comprising a step of attaching a printed transparent film to a contrast medium.

  According to the decorative shadow illumination device and the contrast pattern manufacturing method of the present invention, by configuring as described above, the contrast pattern is projected directly onto the shadow projection surface as in the prior art, and a shadow is projected from the back side of the projection surface. Rather than appreciating, the light and shadow transmitted through the contrast medium are projected toward the shadow projection plane, and the shadow projection is projected onto the shadow projection plane in the vertical direction, and the viewer appreciates the shadow through the light and shadow. Therefore, a shadow image appears brightly near the decorative shadow lighting device, and becomes thinner as it moves further upwards, and the contrast between light and shade is exquisite, fantastic and extremely excellent from an artistic point of view. Has an effect. In addition, a cover provided with a light or black light in a cover that covers the decorative shadow illumination device has an effect that can be used as a row lamp because the cover serves as a lamp shade. According to the method for producing a contrast pattern, it is convenient because a contrast pattern as a base picture can be easily created in order to obtain a desired shadow picture. The decorative shadow illuminating device of the present invention has a simple structure and is excellent in terms of economy, and since it does not use a projector, it has no fan noise and is excellent in terms of maintenance-free.

  The best mode for carrying out the present invention (hereinafter referred to as “embodiment”) will be described in detail below. FIG. 1 is a perspective view showing an example of a decorative shadow illuminating device according to an embodiment of the present invention, FIG. 2 is a development view showing the inside of a cover, and FIG. 3 shows a lamp of a light source. FIG. 4 is an explanatory diagram showing a state in which the decorative shadow illumination device of the embodiment is used.

  In FIG. 1, reference numeral 1 denotes the decorative shadow illuminating device, which includes a contrast body 2 in which a contrast pattern 21 is provided on a curved surface 20 having transparency or light transmission, and light toward the contrast body 2. A light source 3 for irradiation and a cover 5 provided with an opening 50 through which light emitted from the light source 3 and transmitted through the contrast body 2 passes toward the shadow projection surface 4 are provided. The cover 5 includes a back plate 51 provided below and opposite to the shadow projection surface 4, a front shade 52 having light transmissivity continuously provided on the back plate, and the back plate and the front shade. The top shade 53 is provided with a light-transmitting property so as to cover 52 from above, and incisions (50a, 50b) provided in the upper end portion of the back plate and the rear end portion of the top shade constitute the opening portion 50, respectively. Yes. The light and shadow irradiated from the light source 3 and transmitted through the contrast body 2 pass through the opening 50 and form a shadow extending in the vertical direction on the shadow projection surface 4 located behind the back plate 51. The light source 3 and the contrast body 2 are arranged on the pedestal 6 and covered with the cover 5.

  The contrast body 2 in this embodiment is formed of a plate-like body having transparency or light transmission, and is curved from an intermediate portion irradiated with light emitted from a light source to an upper portion. And it is attached to the lower part of the back plate 51 so that the curved part faces the inside of the cover 5. The material of the contrast body 2 is not particularly limited, but is a plastic that can be easily molded, and for example, polyacrylate, polyvinyl chloride, polystyrene, polyethylene, polypropylene, polycarbonate, polyethylene terephthalate, and the like are preferable. In particular, polymethacrylate, polyvinyl chloride, and polystyrene are particularly preferable because they are excellent in transparency, moldability, and dimensional stability. The plastic is molded into a predetermined shape by extrusion molding, injection molding, compression molding, cast molding or the like. A flat plate may be formed into a curved shape by post-processing.

  In order to provide the contrast pattern 21 on the curved surface 20 of the contrast body 2, for example, printing may be performed directly on the curved surface 20 of the contrast body 2 by an ink jet method or a transfer method, or a spraying method or handwriting may be used. Or you may affix on the curved surface 20 of the contrast body 2 what preliminarily printed the contrast pattern 21 on the transparent film. In this case, it is preferable to select a sticking adhesive or pressure-sensitive adhesive that does not impair transparency and is difficult to move to the contrast body 2. The ink or paint used for the contrast pattern 21 is mainly composed of, for example, titanium dioxide having a strong hiding power for the light-shielding pattern portion that forms the shadow. Titanium dioxide may be either anatase type or rutile type, but rutile type is preferred when discoloration and whiteness are important. When it is desired to color the light transmitting portion, it is preferable to use a transparent coloring material such as an organic pigment or dye. Thus, a shadow picture that looks more beautiful is obtained by the colored light transmitted through the contrast-enhanced picture 21 that is transparently colored. In FIG. 2, the contrast pattern 21 is colored black for easy understanding, but is actually colored white by titanium white paint.

  In the decorative shadow illuminating device 1 according to the embodiment of the present invention, light and shadow transmitted through the contrast body 2 are irradiated obliquely upward with respect to the shadow projection plane 4, and the shadow is projected onto the shadow projection plane 4 in the vertical direction. Therefore, the shape of the contrast pattern 21 and the shadow projected on the shadow projection plane 4 are different from each other. That is, since the shadow projected on the shadow projection plane 4 is stretched as it goes above the shadow projection plane 4, it is necessary to prepare a contrast pattern 21 that deforms the original picture so as to shrink as it goes upward. As an example of the production of the contrast pattern 21, for example, as shown in FIG. 5, a square cell (a) in which the Y axis is gradually reduced toward one end like a semilogarithmic scale is formed on the curved surface 20 of the contrast body 2. When pasting so that the Y-axis is in the vertical direction of the shadow picture and the squares reduced above the shadow picture are facing, a shadow picture composed of square squares (b) is projected on the shadow picture projection plane 4. If the original image reduced at the same scale as above is used as the contrast pattern 21, the shadow image is projected in the same shape as the original image. The ratio of the grid length on the Y-axis of the contrast pattern 21 to the length of the shadow grid corresponding to this is the scale at each grid position.

  From the above, a description will be given of a method for obtaining a contrast-purpose pattern 21 that displays a shadow with the same shape as the original picture using a computer. The coordinates corresponding to the graph paper representing the original image and the scale in the Y-axis direction are input to the computer in advance to the computer, and then the original image of the desired shape is input to the computer by an input device such as a scanner and input. The generated original image is plotted at the coordinates in the file. Next, the coordinates in this file are reduced in the Y-axis direction according to the scale. The picture on the reduced coordinates is printed on a transparent film by an output device such as a printer or a plotter. This printed transparent film is attached to the curved surface 20 of the contrast body 2 so that the Y axis is in the vertical direction of the shadow picture, and the contrast pattern 21 is completed. Instead of printing on the transparent film, printing may be performed directly on the curved surface 20 of the contrast body 2. When this contrast pattern 21 is projected, a shadow picture similar to the original picture is projected on the shadow projection plane 4. The above procedure is executed by a computer program. According to this method, if the scale is the same, a contrast pattern can be easily created for any original image. Although the procedure has been described in a simplified manner, in practice it is preferable to make corrections on a computer based on more accurate distortion data.

  Next, the light source 3 that irradiates light toward the contrast body 2 will be described. The light used for the light source 3 is not particularly limited. However, it has become clear from experience that a filament 31 having a reverse U-shape as shown in FIG. That's what it means. That is, in the inverted U-shaped filament 31, the light emitted from the horizontal filament part (HF) clearly shows the horizontal line part of the shadow, and the light emitted from the two parallel vertical filament parts (VF) In particular, as a result of clearly displaying the vertical line portion of the shadow picture, the entire shadow picture is clearly projected. In FIG. 3, LD indicates the direction of light. Moreover, it is preferable that the light used for a light source is within 16V and 0.7 amperes. If it is brighter than this, it will be difficult to form a shadow picture, and if it is too dark, there is a possibility that light will not reach for a long time. It is preferable that the reflector 30 of the light used for the light source softens the reflected light by applying a silver paint on the mirror surface to prevent the occurrence of shadow unevenness. This is because if the mirror surface is too strong, the light from the light source may be reflected in the shadow and may cause unevenness.

  As described above, the cover 5 includes the back plate 51, the front shade 52 provided on the back plate continuously with light transmission, and the light transmission covering the back plate and the front shade 52 from above. And the top shade 53. The back plate 51 is preferably a plate-like body having shape retention such as wood or plastic. The front shade 52 and the top shade 53 may be formed by applying a desired picture pattern to a light-transmitting material, for example, a milky white plastic sheet, or by bonding a paper on which a picture pattern is printed. The ceiling shade 53 according to the present embodiment has a shape obtained by vertically dividing a cylinder, but is not limited to this shape, and may be a polygon or the like. A rectangular cut 50a is provided at the upper end of the back plate 51, while a trapezoidal cut 50b having a width substantially the same as the cut 50a is provided at the rear end of the top shade 53. These cuts constitute the opening 50. The aperture 50 acts to irradiate the shadow projection plane while maintaining the substantially parallel state by controlling the width of the aperture 50 and the shadow irradiated from the light source and transmitted through the contrast medium. Since the size and shape of the notch are closely related to the position and orientation of the light source, it is preferable to adjust appropriately so that an optimal shadow picture is projected.

  Next, in order to enhance the decorative effect of the front shade 52, it is preferable to provide either or both of light and black light in the cover. When the black light 7 is provided, as shown in FIG. 2, it is preferable to apply a fluorescent material 70 to the inner peripheral surface of the front shade 52 and irradiate the fluorescent material 70 with the black light 7 to emit light. The black light 7 emits ultraviolet rays, and the ultraviolet rays hit the fluorescent material 70 to emit fluorescence. A reflecting plate 71 may be provided below the back plate 51 so that this fluorescence is more strongly reflected in the front shade 52.

  The decorative shadow lighting apparatus 1 according to the embodiment was created. The contrast body 2 was curved from the center to the top of the polymethacrylate plate. As shown in FIG. 3, the image for contrast enhancement is obtained by taking an original image of a flower with a camellia into a computer with a scanner and reducing the deformation in the Y-axis direction using the method described in the embodiment with a transparent adhesive. It printed on the transparent film and affixed this on the curved surface 20 of the contrast body 2 so that a Y-axis may become the vertical direction of a shadow picture. In addition, a white projection paint 4 was applied to the entire surface of the plywood material as a shadow projection surface 4, and the decorative shadow illumination device 1 was arranged in close proximity to the shadow projection surface 4. The light source light used was a Hitachi 16V, 0.7A U-shaped filament, and the black light used was Toshiba 15W. When the surroundings of the decorative shadow lighting device 1 were slightly darkened and the light source was switched on, as shown in FIG. 4, a fantastic shadow was projected on the shadow projection surface 4 along with long vertical light. The decorative shadow illuminating device of the present invention was exhibited at the Lighting Fair held at the Tokyo International Exhibition Center from March 1st to 4th, 2005, and attracted the attention of those who visited the exhibition hall. Add that.

  The decorative picture lighting device according to the present invention is extremely useful because it is widely used as a decorative lighting device for events or as a decorative lighting device for offices, stores, residential living rooms, reception rooms, bedrooms, etc. It is.
