Description

Detailed Description of the Invention

  The present invention relates to a plant used for interior and the like and a decoration method using the plant.

  Conventionally, for example, Japanese Patent Application Laid-Open No. 2000-140747 proposes to produce an ornamental plant in which dried flowers, dried plants, and artificial flowers are coated with a fluorescent dye to emit fluorescence in the dark.

Problems that patents try to solve

  However, the above-mentioned plants are so-called dead plants and can be enjoyed by appreciating fluorescent light in the dark. However, they can provide effects as growing plants that provide healing to humans during the day. There wasn't. On the other hand, growing plants such as ordinary potted plants can appreciate the shape and color of flowers and leaves during the day, but not in the dark.

  The present invention solves the above problems, and provides a plant that can be appreciated in the daytime and in the dark.

Means for solving the problem

  1st invention of this application consists of a fluorescent dyeing plant characterized by apply | coating the fluorescent component to the leaf of the plant in growth, the surface of a petal, or a stem.

  A second invention of the present application comprises a decoration method characterized in that visible light is emitted by irradiating a fluorescent dyed plant coated with the fluorescent component with ultraviolet light.

  3rd invention of this application consists of a fluorescence dyeing plant which apply | coated several types of fluorescence components which light-emit visible light of a different color.

Details of the present invention will be described below. The same numbers in the drawings have the same functions.
A first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is one example of implementation on growing plants such as potted plants.
FIG. 1 is a diagram of daytime, and a houseplant 1 is planted in a flower pot 2. The foliage plant 1 is coated with a fluorescent dye containing a fluorescent component only on the surface of the leaf 4 and the stem 3. In the vicinity of the flower pot 2, a ring-shaped black light 5 that emits ultraviolet light is arranged by a support tool (not shown). During the day, the black light 5 is not turned on and can be viewed as a normal houseplant.

  FIG. 2 is a diagram of the plant 1 in the dark. The black light 5 is turned on, the ultraviolet light is irradiated to the plant 1, and only the surface of the leaf 4 and the stem 3 to which the fluorescent dye is applied emit visible light. A decorative product combining a houseplant coated with a fluorescent component and black light has a value as a novel indoor interior as an unprecedented shining plant. What was viewed as a normal foliage plant during the daytime can be used as a plant interior with an unprecedented impact because it emits light in the dark or at night.

  As a method of applying a fluorescent component to a foliage plant, JP-A-2000-140747 proposes coating the fluorescent component on the whole plant by a dipping method or the like. However, such a method can be applied to dead plants such as dried flowers, but when applied to a growing plant according to the present invention, the plant is clogged and cannot breathe and die. For this reason, it is important that the fluorescent component is not applied to the back surface of the leaf having a large distribution of pores, but only the surface of the leaf or the stem portion. For this reason, using a brush, spray, etc., apply carefully so that the fluorescent component does not adhere to the back side of the leaf. In this way, the applied plant can grow for a long time without withering or defoliating.

As the fluorescent dye applied to the growing plant, any dye can be used as long as it is dissolved in water, not dissolved in an organic solvent. For example, there are fluorescent dyes such as trade name “Kyaphor” of Nippon Kayaku Co., Ltd. and trade name “Whiteex” of Sumika Chemtex Co., Ltd., which are water-based fluorescent dyes, which are used by dissolving in water.
Since the surface of the plant has a waxy structure called a cuticle layer and may repel water, a small amount of a surfactant may be added if necessary.

  Ultraviolet light is a general term for light having a wavelength of 10 nm to 380 nm, and any substance having an emission spectrum in the absorption wavelength region of a fluorescent component can be used as a light source to emit the fluorescent component in the dark. It is. However, depending on the wavelength, an adverse effect on the human body is caused. Therefore, it is preferable to use an ultraviolet lamp that emits ultraviolet rays having a wavelength of 315 nm to 400 nm called so-called near ultraviolet rays or UV-A. As such an ultraviolet lamp, for example, trade name “Black Light Blue (BL-B)” from NEC Lighting Co., Ltd., trade name “Black Light Fluorescent Lamp” from Toshiba Lighting & Technology Corporation can be used.

  In addition, the fluorescent component in the present invention includes not only those that emit visible light when irradiated with ultraviolet rays, but also includes the use of so-called luminous pigments that emit fluorescence themselves. The phosphorescent pigment absorbs the energy of the light irradiated during the day and emits light at night. For example, TDO Graphics Co., Ltd. (Chiyoda-ku, Tokyo) trade name is a silicon aluminate phosphorescent pigment. “TDO Hikarimasu” and Nemoto Special Chemical Co., Ltd. (Suginami-ku, Tokyo) sell the product name “N Luminescent” which is an aluminate compound. When applying to plants, since it is dispersed in water and applied, if the water resistance of the pigment is insufficient, it is necessary to perform a water-resistant coating treatment on the surface of the phosphorescent pigment as necessary. Aluminate phosphorescent pigments are preferably used because they are water resistant and do not require a coating treatment.

  In the case of using the luminous component as described above, an illumination device that emits ultraviolet light is not necessary, so that it is not necessary to replace an electric wiring or a dry battery, and the interior of a plant that emits fluorescence can be easily obtained. Alternatively, it can be applied to outdoor plants such as gardens, and can be installed in various places.

A second embodiment of the present invention will be described with reference to FIGS.
FIG. 3 shows one example of a potted plant having white flowers.
In FIG. 3, the white poinsettia 6 is arranged in a substantially oval spherical transparent plastic container 7. The poinsettia 6 has six white flower buds 8a, 8b, 8c, 8d, 8e, 8f on the top and green leaves 9 on the bottom. Fluorescent components that are colorless under visible light but emit blue light when exposed to ultraviolet light are on the surfaces of the flowers 8a and 8d, fluorescent components that emit green light are on the surfaces of the flowers 8b and 8e, and fluorescent components that emit red light are flowers. It is applied to the surfaces of 8c and 8f.

  A UV unit 11 is disposed on the top of the container 7. The UV unit 11 contains a dry battery 12 and an electronic circuit 13. A plurality of ultraviolet LEDs 14 are attached to the lower part of the UV unit 11, and an optical sensor 15 is attached to the upper part. The light sensor 15 of the UV unit 11 detects the brightness of the surrounding environment, and when the surrounding of the container 2 becomes dark and the brightness falls below a set value, the voltage is automatically applied to the ultraviolet LED 14 by the electronic circuit 13. Applied and irradiated with ultraviolet light.

  FIG. 4 is a diagram of poinsettia 6 at night. The ultraviolet LED 14 irradiates the poinsettia 6 with ultraviolet light, and the florets 8a and 8d emit blue, the florets 8b and 8e emit green, and the florets 8c and 8f emit red. Thus, in the daytime, when white florets are at night, there are no other foliage plants that emit light in different colors.

  Furthermore, when half of the ultraviolet LEDs 14 are white LEDs, and the electronic circuit 13 alternately turns on the white LEDs and the ultraviolet LEDs at regular intervals in the dark, the normal poinsettia in the daylight and ultraviolet Since the appearance of poinsettia that emits a fluorescent color with light appears alternately, the difference can be clearly presented and a strong impression can be given. Since poinsettia is used especially as a Christmas foliage interior, such a decoration method has a great effect as a fantastic decoration for Christmas night.

  Various fluorescent components can be used as the fluorescent component used here. For example, it is substantially colorless or white under visible light, and emits different colors under ultraviolet light. "MLCB-12" with green light emission, "MLCB-13" with blue light emission, and "MLCB-18" with red light emission are on the market. Alternatively, trade names “Magic Lumino Paint Green”, “Magic Lumino Paint Blue”, and “Magic Lumino Paint Red”, which are fluorescent paints using the fluorescent pigment, may be used.

  In this example, the fluorescent component was applied only to the surface of the floret in order to enhance the decorative effect. It is possible to apply a fluorescent component to the leaf, but it is not applied to the back of the leaf with a large distribution of pores, but only to the surface of the work so as not to disturb the respiration of the plant.

  In this embodiment, the fluorescent component of light emission having a different color is applied to the white floret. However, the present invention can be applied to any plant as long as it has white leaves and petals. Examples of white petal plants include roses, lilies, cyclamen, orchids, and colors.

  As another embodiment using these white flowers, for example, on each wedding table, a flower pot in which a fluorescent component is applied to the flower petal is placed, and a candle is attached to the center of these flower pots. In addition, if the LED of the bride's candle service is incorporated with a UV LED, the bride turns around the table and ignites the candle. The effect that can be obtained.

  As a plant having white leaves, the entire leaf does not need to be white, and benjamin, pothos, caladium, kannonchiku, etc. having so-called speckled leaves can be used. In this case, it is only necessary to apply the fluorescent component to the white part with a brush. The white spotted part has no chlorophyll, so even if it is applied, it has no effect on photosynthesis and can reduce adverse effects on plant growth. Moreover, it is decoratively advantageous as a fantastic interior that the leaves emit light partially rather than the whole leaves emit light.

  In this example, an ultraviolet LED was used as the ultraviolet light source. The ultraviolet LED is small and light, and emits high-intensity ultraviolet light simply by applying a low-voltage DC voltage, so that the illumination device can be made compact, and various shapes of ultraviolet irradiation devices can be manufactured. Moreover, since it operates with a dry battery as in this embodiment, it is not necessary to connect to a 100 V power source, and it can be easily installed at any location. As such ultraviolet LED devices, NS365D (peak wavelength 365 nm), NA370D (peak wavelength 370 nm), NS375D (peak wavelength 375 nm) are sold by, for example, Nitride Semiconductor Co., Ltd. It is only necessary to select one having an optimum wavelength distribution according to the absorption wavelength. However, it goes without saying that other ultraviolet light sources such as an ultraviolet lamp may be used.

  The plant used in the present invention can be of any kind such as herbaceous or woody. Further, not only plants that grow with roots such as potted plants and standing trees but also plants such as cut flowers that still have a water-absorbing function even after the roots are cut and grow.

  As described above, fluorescent dyes, fluorescent pigments, phosphorescent pigments and the like are used as the fluorescent component in the present invention. It can be used in various forms such as dissolution, dispersion as fine particles or emulsion.

  As a solution containing a fluorescent component in the present invention, when used for growing plants, it is desirable to use only water as a solvent, but as a mixture with a solvent that dissolves in water such as alcohols. Also good.

The invention's effect

  According to the present invention, a fluorescent component is applied to a plant, the fluorescent component is retained in the plant, and the fluorescent dye or fluorescent pigment is emitted by irradiating the plant with ultraviolet rays in the dark, or by self-emission of the phosphorescent pigment. By making the plant emit light, a novel decorative effect of the plant can be obtained.
