[Prior art]

 Traditionally, entertainment stores such as pachinko parlors and restaurants have been using decorative lighting fixtures for advertising. As such a lighting fixture for decoration, for example, one shown in FIG. 5 is known. In the luminaire shown in FIG. 5, a large number of small light bulbs 2 serving as light sources are arranged on a base 1 made of iron or plastic. This light bulb 2 has, for example, as shown in FIG. 5 (A), columns a, b, c, d, e ... in the horizontal direction in the figure and four rows a, b, c, d in the vertical direction in the figure. Are evenly spaced from each other. Further, reference numeral 4 in FIG. 5 (A) is a controller for rectifying the electric power from the AC power supply 5 and controlling the flow blinking described later. When using this luminaire, first, for example, all 16 light bulbs 2 in the range of 4 columns a, b, c, d and 4 rows a, b, c, d are blinked at once. Let Then, immediately after that, the four light bulbs 2 in the row of a are turned off and at the same time the four light bulbs 2 in the row of e are blinked (in the end, four rows of b, c, d, e and a, The 16 light bulbs 2 in total in the range of 4 rows of C, C and D are blinking). Furthermore, immediately after that, the four light bulbs 2 in the row b are turned off, and at the same time, the four light bulbs 2 in the row f are blinked (after all, the four rows c, d, e, and f, and a, b, and b). , That is, the 16 light bulbs 2 in total in the range of 4 rows of 2 are blinking). Thereafter, similarly, while sequentially turning off the light bulbs 2 in each row in the directions of a 1, b, c, ... (Arrow α direction in the figure), at the same time, the directions of e, f, g ,. ) Make the light bulbs 2 in each row blink in sequence. As a result, initially, the rectangular planar light formed by the 16 light bulbs 2 in the range from the columns a to d and the rows a to d is sequentially turned in the direction of the arrow α in the figure. , It seems to flow while blinking (so-called flow blinking), and it is possible to attract the eyes of the viewer. In addition, FIG. 5B shows a cover for covering the base 1 on which the light bulb 2 is arranged. The cover 3 is for making the light from the light bulb 2 more effectively visible to the viewer. For example, by coloring the cover 3 with an arbitrary color such as red, more effective illumination can be performed for decoration.

[0003]

[Problems to be solved by the device]

 However, in such a conventional luminaire, for example, in the above example, in order to produce an effect of decorative illumination, there are four columns in a, b, c, d ... And four rows in a to d. Since a total of 16 light bulbs 2 need to be repeatedly blinked (or turned on) and turned off for a certain period of time for performing decorative illumination, there is a problem that a large amount of power is consumed. The present invention has been made by paying attention to such problems of the conventional decorative lighting fixtures, and achieves the same effect of decorative lighting such as flow blinking with the conventional power consumption with significantly less power consumption. It is an object of the present invention to provide a decorative lighting device that can be used.

[0004]

[Means for Solving the Problems]

 The decorative lighting device of the present invention for achieving the above object is a decorative lighting device including a light source and a transparent member provided at a position through which light from the light source passes, wherein the transparent member is substantially It is characterized in that only a plurality of strip-shaped cylinders having a circular or elliptical cross section are formed in a continuous shape in a direction perpendicular to the longitudinal direction, and the whole is made of a uniform material. . Further, in the present invention, the transparent member may be formed in a shape in which a plurality of strips having a substantially semicircular or semielliptical cross section are continuous in a direction perpendicular to the longitudinal direction.

[0005]

[Action]

 As described above, in the decorative lighting device according to the present invention, the transparent member interposed between the light source and the viewer has a plurality of strip-shaped tubular bodies each having a substantially circular or elliptical cross section. It is formed in a continuous shape in a direction perpendicular to the direction, and the whole is made of a uniform material. Therefore, the light from only one light source passes through this transparent member, is dispersed into the same number as the number of the above-mentioned strip-shaped tubular bands, and reaches the viewer. In other words, even if there is actually only one light source, the viewer will see as if there are as many light sources as the number of the strip-shaped tubular strips. Therefore, it is not necessary to use a plurality of light sources to generate the illumination having the line spread as in the conventional case, and it becomes possible to generate the illumination having the line spread with only one light source. Further, unlike the conventional case, it is not necessary to blink (or turn on) all the light sources in the range between the horizontal example and the vertical row in order to generate the illumination having the spread of the surface. With just one light source, it will be possible to produce illumination with a spread of both vertical and horizontal planes. Further, as described above, even when using a transparent member in which only a plurality of strips having a substantially semicircular or semielliptical cross section are formed in a continuous shape in a direction perpendicular to the longitudinal direction, Exactly the same effect can be produced.

【Example】

 The present invention will be described below based on the illustrated embodiments. FIG. 1 is an exploded perspective view showing a lighting fixture according to an embodiment of the present invention. In this embodiment, in FIG. 1, in the center of the plastic belt-shaped base 11 shown in FIG. 1 (A), the light bulbs 12 are arranged in rows a, b, c, d, ... Are arranged in a row (light emitting diodes may be used instead of light bulbs). The base 11 is covered with a cover 13 shown in FIG. 1 (C). In this embodiment, the transparent member 14 shown in FIG. 1B is prepared. The transparent member 14 is made of transparent acrylic resin, and is integrally formed into a shape in which strip-shaped tubular bands 14a, 14b, 15c, 14d having a substantially circular cross section are connected to each other in a direction perpendicular to the longitudinal direction. . The transparent member 14 is formed by filling the inside with the transparent acrylic resin. The transparent member 14 is arranged between the base 11 and the cover 13. Reference numeral 4 is a controller for rectifying the AC power from the AC power supply 5 and controlling the flow blinking.

Next, the operation of this embodiment will be described. When using this embodiment, first, the four light bulbs 12 a, b, c, and d in FIG. Then, immediately after that, the one light bulb 12 of a is turned off and the one light bulb 12 of e is blinked at the same time. Immediately thereafter, the light bulb 12 of b is turned off and the light bulb 12 of f is blinked at the same time. Thereafter, similarly, while sequentially turning off the light bulbs 12 in the directions of c, d, e, f ... (Arrow α in the figure), at the same time, the directions of g, h, i, j ... (Arrow α in the figure). Direction) to sequentially blink each light bulb 12. As a result, when only the light bulb 12 on the base 11 is viewed, the four light bulbs 12 a to d first flash in a linear shape, and then the linear lighting portions are sequentially changed to b, c, d, and e. , And further to c, d, e, and f in the direction of arrow α in the figure (flow blinking).

Furthermore, in this embodiment, the transparent member 14 causes the linear blinking portion to have the planar illumination described in FIG. 5 (that is, four rows of a to d and a to d of FIG. 5). It is possible to produce the same lighting effect as the lighting of a rectangular surface with 16 light bulbs (4 rows in total). This is because, as described above, in this embodiment, the transparent member 14 having four circular cross sections in the vertical direction of the drawing is provided in front of the light source. Therefore, the light from one light source 12 passes through these four circular cross sections, and is divided into four light images by the respective strip-shaped tubular zones 14a to 14d as shown in FIG. 2 (A). Then, it comes into view of the viewer 15. Therefore, as shown in FIG. 2B, the observer 15 looks as if there is light from one light source, as if there were light from four light sources. Therefore, in the present embodiment, by using only one-fourth the number of the light bulbs 12 of the conventional lighting fixture shown in FIG. 5, the same lighting as the conventional lighting fixture of FIG. 5 is used. It becomes possible to produce an effect (for example, an effect in which planar light seems to flow while blinking in the direction of arrow α). Therefore, according to the present embodiment, it is possible to realize the same flow-blinking decorative lighting effect as in the conventional case with a power consumption of approximately one fourth that in the conventional case.

Next, FIG. 3 is a perspective view for explaining another embodiment of the present invention. That is, in the embodiment of FIG. 1, the cross sections of the strip-shaped tubular strips 14a to 14d of the transparent member 14 are formed in a substantially circular shape, but the present invention is not limited to this. For example, a transparent member 21 integrally formed in a shape in which strip-shaped tubular bands 21a to 21d having a substantially elliptical cross section as shown in FIG. 3A are connected to each other may be used. Alternatively, a transparent member 22 integrally formed in a shape in which strip-shaped tubular bands 22a to 22d having a substantially elliptical cross section are connected to each other may be used.

FIG. 4 is a perspective view for explaining another embodiment of the present invention. In this further embodiment, the transparent member 23 is integrally formed in a shape in which strips 23a to 23d having a semicircular cross section are connected to each other as shown in the figure. As described above, even when the transparent member 23 has a semicircular cross section, it is possible to obtain the same effect as that of the embodiment of FIG. Although not shown, the same effect can be obtained by using a transparent member integrally formed in a shape in which band-shaped bodies having a semi-elliptical cross section are connected.

In all of the examples shown in FIGS. 1 to 4 above, the transparent members 14, 21, 22, 23 are formed in a shape in which four strips are connected, In the present invention, the number of strips is not limited to four, and any number of strips may be used. Further, in the above embodiments, the transparent members 14, 21, 22, and 23 are all integrally formed of transparent acrylic resin, but the present invention is not limited to this, and the material of the transparent member is Any transparent material such as polyester resin or glass may be used. Further, the shapes of the base 11, the transparent members 14, 21, 22, 23, and the cover 13 are not limited to the strip-shaped rectangular shape, but may be any shape such as a square frame shape or a circumferential shape. It is possible to

[Effect of device]

 As described above, in the decorative lighting device according to the present invention, the transparent member interposed between the light source and the viewer has a plurality of strip-shaped tubular bodies each having a substantially circular or elliptical cross section. It is formed in a continuous shape only in the direction perpendicular to the longitudinal direction, and is entirely made of a uniform material. Therefore, the light from only one light source passes through this transparent member, is dispersed into the same number as the number of the above-mentioned strip-shaped tubular bands, and reaches the viewer. In other words, even if there is actually only one light source, the viewer will see as if there are as many light sources as there are the above-mentioned strip-shaped tubular bands. Therefore, unlike the conventional case, it is not necessary to use a plurality of light sources to generate the illumination having the line spread, and it becomes possible to generate the illumination having the line spread with only one light source. Further, unlike the conventional case, it is not necessary to blink (or turn on) all the light sources in the range between the horizontal direction and the vertical row in order to generate the illumination with the spread of the surface. With only one light source of, it becomes possible to generate illumination with a surface spread. Therefore, the effect of decorative lighting, which is almost the same as that of conventional lighting fixtures, can be achieved with a significantly smaller number of light sources than conventional lighting fixtures. It is possible to create a decorative lighting effect. Also, as described above, even when using a transparent member in which only a plurality of strips having a substantially semicircular or semielliptical cross section are formed in a continuous shape in a direction perpendicular to the longitudinal direction, Almost similar effects can be produced.
