"Prior Art" With the recent pet boom, the number of people who wish to keep dogs, cats, small birds, etc. is increasing. However, in Japan's housing situation, keeping dogs, cats, etc. in condominiums is strictly prohibited, and the types of pets that can be kept are extremely limited. Goldfish, tropical fish, and other fish that can be kept in aquariums are becoming increasingly popular as pets that can be kept in apartments and the like.

"Example" 7th 11N is a perspective view showing a molded object placed in a water tank to explain an example of the present invention based on the drawings. In this aquarium, there are natural stones 1.1..., watermill 3, mat member 4, cobblestones 5.5..., seaweed 61, underwater flowers 62, fish 71, and shellfish 72. , a seahorse 73, and a fry breeding room 8 are arranged. These natural stones 1, ■, etc. are made of polycarbonate resin and fluorescent dye and have light-gathering properties! It is composed of fat.

Polycarbonate resin corresponds to a translucent plastic, and is not limited to polycarbonate resin, but acrylic resin or the like can also be used. This light-harvesting resin is an optically pure colored polymer that has the property of focusing and transmitting light. Therefore, direct light and dispersed light from the surroundings are absorbed and emitted as fluorescence within the polycarbonate resin, and this fluorescence is propagated to the edge portions 100. Fluorescence is emitted from 100...

Here, the principle by which fluorescence is emitted from the edge portion will be explained in detail.

FIG. 11 is a diagram illustrating a state in which projected light enters the plate member 10 made of light-condensing resin and is absorbed by a highly pure fluorescent dye. Fluorescence is emitted randomly within the plate member 10. According to the law of total reflection, a portion of the projected light passes through the plate member 10 as F2, F3, and F4. And the rest of F! passes through the complementary area and escapes from the plate member 10.

As a result, the ratio of fluorescence F2, F3, and F4 to the total projected light depends on the refractive index of the plastic, and can be expressed as follows.

(n2-1) Σ(F2, F3, Fa)- ・ ・ ・ ・ ・ ・ (1) For example, when the refractive index n is about 1.45 to 1.60, this ratio (F2, F3, F4) is 70-80%
reach. That is, if 100 photons hit,
Of the 75% of the light that passes through the plate 10, 20-30% is absorbed by the dye, and approximately 40% of the photons are emitted to the edges of the plate 10. transmitted and radiated from it.

In order to emit particularly strong fluorescence from the edges, it is necessary to maximize the absorption and emission of light by the fluorescent dye, which requires minimizing the overlap between absorbed light and diverging light.

Therefore, it is necessary to use a light-condensing resin in which the maximum wavelength of absorbed light and the maximum wavelength of diverging light are different from each other.

Next, the modeled object of this example will be explained based on FIGS. 2 to 10.

00... Therefore, the translucent plastic and the fluorescent dye absorb direct light and dispersed light from the surroundings of the aquarium, emit it as fluorescence within the plastic, and the fluorescence is reflected by total internal reflection. The fluorescent light is caused to propagate and emit fluorescence from the edge portions 100 and 100. Therefore, the natural 1.1 emits fluorescent light and shines, and the emitted fluorescent light is emitted outside the aquarium through the surrounding water.

In this case, unlike in the air, the atmosphere creates an atmosphere in which light accumulates in the water, which has the effect of brightening the entire aquarium. In other words, the phosphorescent effect of water can make the entire aquarium shine.The objects are not limited to natural objects, but can also be abstract structures like those that appear in science fiction movies, such as shapes that combine hexagonal columns, etc. can do.

has an appropriate shape, and the edge part 1 of this boulder 5
Since fluorescence can be emitted from 00, 100, . . ., the boulder 5 itself shines, and the area around the bottom of the aquarium can be brightened. Note that since the general light-concentrating resin has a specific gravity of 1 or more, it can be placed on the bottom of the aquarium.

In FIG. 7, the shaped object placed in the aquarium is seaweed 61, and the seaweed 61 is made of light-concentrating resin made of polycarbonate resin and fluorescent dye.

The stem portion of this seaweed 61 is composed of grooves or uneven portions. Therefore, these uneven portions and groove portions also form edge portions 100, 100, and so on.

The fish 71 and shellfish 72 are made of light-harvesting resin made of polycarbonate resin and fluorescent dye. If the specific gravity of the fish 71 and the condensing resin is close to 1, the fish 71 can be suspended in the aquarium according to the flow of water by an air pump or the like. Since fluorescence is emitted from the edge portions 100, 100 formed on the fish 71, there is an effect that a dynamic glow can be realized.

Furthermore, it is also possible to arrange the shellfish 72 on the bottom of the aquarium and make the fluorescence emit from the edge portion 100.100 of the shellfish 72. It is also possible to attach a light-condensing resin shaped like a pearl or the like inside the shell 72. The seafood employed as the modeled object is not limited to the fish 71 and shellfish 72, but may also include seahorses 73 and other living creatures. In addition, without being limited to real creatures, it is also possible to employ characters with an underwater theme, such as mermaids and monsters.

FIG. 10 is a diagram illustrating a case where the shaped object placed in the aquarium is a fry nursery room 8 for raising fry. The fry nursery room 8 is made of light-harvesting resin made of polycarbonate resin and fluorescent dye. The fry nursery room 8 constitutes a room with an appropriate shape, and a plurality of small holes 81, 81, . . . are bored in the fry nursery room 8. These small holes 81, 81... allow water to flow freely, but are so small that young fish cannot pass through them. Therefore, it is possible to prevent the young fish from being eaten by large fish in the aquarium. And the edge part 100.1 of the fry nursery room 8
Since the fluorescent light is emitted from 00, the fry nursery room 8 not only shines brightly and is beautiful, but also makes it easier to observe small fry.

This embodiment configured as described above can also be used by replacing the fluorescent lamp placed on the top surface of the aquarium with a black light. A black light is one of the means for generating near ultraviolet rays, and uses a filter to efficiently generate near ultraviolet rays (maximum wavelength 352 nm) that cut visible light and have a strong fluorescent effect. These black lights 1 to 1 can be projected with near ultraviolet rays without raising the surrounding temperature 3, and can make a shaped object formed from a light-condensing resin shine strongly.

Note that the light emitted from a black light is attenuated in inverse proportion to the square of the distance, but objects made of light-harvesting resin placed underwater are attenuated by the light emitted from the black light due to the phosphorescent effect of the water mentioned above. Fluorescence can be emitted with the same brightness at any position without attenuation in inverse proportion to the square of the distance.

Furthermore, a suction cup or the like may be attached to the bottom of the natural rock 1, Ryugu Castle 2, watermill 3, mat member 4, etc. for fixing it to the bottom of the aquarium.

The present embodiment is not necessarily limited to an aquarium in which living things are kept, but can also be applied to an aquarium in which living things are not kept and used exclusively as a display.
