Embodiments of an advertising device according to the present invention will be described below with reference to the accompanying drawings. In addition, this invention is not limited to the following embodiment.
(Embodiment 1)

FIG. 1 is a schematic diagram showing a paper lantern, which is an example of an advertising device according to this embodiment. Based on FIG. 1, the advertising device of this embodiment will be described in detail.

The lantern 1 according to the present embodiment has a cylindrical firebox 2 (body portion) (having a circular cross section in the horizontal direction) that can be stretched in the vertical direction by a bellows structure or the like, and is arranged on the upper part of the firebox 2. An upper wheel 3, a lower wheel 4 arranged below the firebox 2, a first light source 10 arranged inside the firebox 2, and arranged inside the firebox 2 and below the first light source 10. and a filter 30 arranged within the lower ring 4 . In addition, in this embodiment, the 1st light source 10 and the 2nd light source 20 become a light source.

The firebox 2, the upper wheel 3 and the lower wheel 4 are constructed with structures and materials used for general lanterns. Characters, patterns, or the like may be formed on the surface of the firebox 2 . If characters, patterns, etc. are formed on the surface of the fire box 2, the same effect (advertising effect, etc.) as that of ordinary paper lanterns can be obtained.

The first light source 10 is a light bulb such as an incandescent bulb or an LED, and is suspended from an electric wire 21 for supplying electric power from the outside and arranged near the center of the firebox 2 . The light emitted from the first light source 10 spreads in almost 360 degrees, and the light transmitted through the firebox 2 illuminates the side of the lantern 1 and the like. As a result, when viewed from the side, the firebox 2 appears to emit light.

The second light source 20 is a light bulb such as an incandescent bulb or an LED. The light emission direction of the second light source 20 is directed toward the lower wheel 4 .

A disk-shaped filter 30 is arranged inside the lower wheel 4, and the light emitted from the second light source 20 passes through the filter 30 and illuminates the lower part of the lantern 1 at a position separated from the lower wheel 4. is now possible. Here, the method of suspending the first light source 10 and the second light source 20 is not limited to the electric wire 21. For example, in the case of the light sources 10 and 20 with a built-in battery, a cord, a wire, or the like can be used.

The filter 30 is provided with a displayed portion 31 on which characters, marks, illustrations, patterns, etc. are applied. It is displayed (projected) on a display surface 40 such as a certain road surface or floor. In other words, since the portion to be displayed 31 is projected onto the display surface 40 by the second light source 20, the filter 30 is also the portion to be projected. Also, the characters, patterns, and the like of the displayed portion 31 of the filter 30 are not limited, and can be freely formed as desired. For example, it is possible to use a plurality of designs of letters formed on the filter based on durability, or to change the pattern etc. according to the season or purpose of use. A specific example of the displayed portion 31 is shown in FIG.

Here, it is desirable that the second light source 20 is a directional light source and that the diffusion angle θ is 90°. Basically, the light from the second light source 20 illuminates only the portion to be displayed 31 , and may illuminate the entire filter 30 .

The divergence angle θ can be varied as shown in FIG. 2(a) shows a narrow diffusion angle .theta.1, FIG. 2(b) shows a slightly wide diffusion angle .theta.2, and FIG. 2(c) shows a wide diffusion angle .theta.3. The diffusion angle θ can be determined by the irradiation distance D from the emission surface of the second light source 20 to the filter 30, the texture to be displayed, etc., and may be 5° to 70°, preferably 5° to 50°. 5° to 30° is particularly preferred.

The display distance L from the bottom surface of the lower wheel 4 to the surface of the projection unit (display surface 40) varies depending on the location of use. For example, when the lantern 1 is installed near the entrance of a store, for example, it is assumed to be about 20 cm to 50 cm, but indoors, for example, it is assumed to be about 80 cm to 100 cm. The irradiation distance D can be changed by adjusting the electric wire 21 that suspends the second light source 20, and the diffusion angle θ can be adjusted according to the place of use and the purpose of use so that the projection can be projected more beautifully. can be adjusted.

The installation position of the filter 30 can be selected as appropriate. It may be arranged near the upper end 4a of the lower wheel 4 as shown in FIG. 3(a), may be arranged near the center of the lower wheel 4 as shown in FIG. Alternatively, the bottom portion 4b of the lower wheel 4 may be used. In the example of FIG. 3C, it may be provided integrally with the lower wheel 4 . Further, by making the outer shape of the bottom portion 4b larger than the outer shape of the upper end 4a of the lower wheel 4, the light from the second light source 20 can reach every corner of the filter 30 without waste. can be set larger.

Next, the filter 30 will be described with reference to FIG. FIG. 4 is a schematic front view and a schematic cross-sectional view showing an example of a filter.

As shown in these figures, the filter 30 is made of wood, resin material, or the like, and has, for example, a flat plate shape. The filter 30 is basically provided with a transmissive portion and an opaque portion, but may be provided with a semi-transmissive portion. A semi-transmissive portion is a portion that can transmit a portion of light, and can be made of a material that can transmit light in a predetermined range of wavelengths, such as a color filter, or a semi-transparent material. can.

The filter 30 of the present embodiment is provided with a displayed portion 31 serving as a transmission portion. The displayed part 31 consists of characters, marks, illustrations, patterns, etc. In the example shown in FIG. 4, assuming a summer festival, the characters of the festival are given in the center, and the illustration of fireworks is given around it. In other words, the displayed portion 31 is an aggregate of individual characters, marks, illustrations, patterns, etc. projected onto the projection portion.

Although there are various methods for forming the displayed portion 31, the displayed portion 31 formed with the holes 32 is shown in Example 1 of FIG. 4(b).

The displayed portion 31 of the filter 30 is formed by forming a plurality of holes 32 penetrating through the filter 30 in an acrylic plate made of opaque black or the like, and the light from the second light source 20 passes through the holes 32 which are transparent portions. (Refer to the middle arrow in FIG. 4(b)), the displayed portion 31 is projected onto the projection portion below the lantern 1. As shown in FIG.

Example 2 of FIG. 4(c) shows a displayed portion 31 using a transmissive material. The filter 30 in this embodiment is made of a transparent member, and an impermeable portion 31a is formed on the surface of the portion other than the portion 31 to be displayed. The opaque treated portion 31a can be formed by applying a black color or the like, and for example, a formation method such as coating, printing, or pasting can be selected.

The light from the second light source 20 passes through the displayed portion 31, which is a transmissive portion (see the arrow in FIG. 4(c)), so that the displayed portion 31 is projected onto the projection portion below the lantern 1. become.

Since the hole 32 is formed in the displayed portion, air flows into and out of the firebox 2 through the filter 30 . As a result, the air inside the firebox 2 is circulated, and the heat emitted from the two light sources 10 and 20 is not trapped, thus enhancing the safety of the lantern. The holes 32 also allow the water that has entered the fire bag 2 to be discharged.

On the other hand, in Example 2 in which the hole 32 is not provided, the same effect as in Example 2 can be obtained by providing a vent at a location where the light from the second light source 20 does not pass. In addition, by providing a semi-transmissive portion, it is possible to improve the presentation effect, and it is also possible to obtain a gradation effect by changing the amount of light transmitted.

Here, by providing the holes 32 as in the first embodiment, for example, characters such as B and D may not be formed well. In such a case, as shown in the upper part of FIG. 5, a separation portion 32a is provided as an impermeable portion separated from other portions, and each separation portion 32a is attached to a peripheral frame 32b or connected with a wire or the like. do. Here, as the typeface of the characters, it is possible to use a typeface that makes the characters distorted or difficult to see even when projected, in consideration of durability and the like. In this way, a filter with separating portion 32a can be formed. Further, as shown in the lower part of FIG. 5, by forming the holes 32 in a dot shape (forming a plurality of small-diameter holes so that a predetermined pattern is projected), the separating portion 32a is not provided, and characters, for example, are formed. B, D, etc. of can be formed.

As described above, the lantern 1 of the present embodiment can project characters, patterns, and the like downward onto the projection unit in addition to side irradiation, so the production effect (advertising effect) is enhanced. Moreover, by adding a special production effect to the lantern 1, which is a tradition of Japanese culture, a visually warm impression effect is brought about, and an effect of softening people can be expected. Furthermore, the lantern 1 can be used for publicity, advertising, etc., and can project company names, logos, store products, and the like. In addition, at home, you can enjoy the taste of each season. In addition, various effects can be expected at events and the like.
