[0017]
DETAILED DESCRIPTION OF THE INVENTION
Since 請 Motomeko 1-3 embodiment regarding the invention described are common, it is explained as follows.
[0018]
a is a self-luminous material having a luminous property made of a synthetic resin containing an inorganic coloring pigment and a luminous pigment. The structure of this self-luminous body a is as follows.
[0019]
The panel b has a predetermined thickness and has an infinite number of holes 1 at predetermined intervals. The size of the hole 1 is usually about 12 mm in diameter, and the thickness of the panel b is about 3 mm. However, it is not limited to the above dimensions.
[0020]
The self-luminous body a has a maximum diameter of about 14 mm and a height of about 7 mm.
[0021]
The self-luminous body a has the following configuration.
[0022]
A projecting light emitting / emitting section 4 having both functions of storing and emitting light is provided on the upper portion of the projecting portion that projects from the surface portion 2 of the panel b. Then, a fitting insertion portion 6 having a diameter slightly smaller than the diameter of the bottom surface portion 5 is formed so as to protrude below the bottom surface portion 5 of the light storage and emission portion 4. And the said insertion part 6 has a diameter which can be inserted in the hole 1 of the said panel b. Further, an end portion of the fitting insertion portion 6 is extended to form a hook portion 7 that protrudes from the back surface portion 3 of the panel b and is locked. The shape of the hooking portion 7 is not limited, but as an example of implementation, it may be curved as shown in FIG.
[0023]
Moreover, you may form the said light emission / storage part 4 in the curved shape seeing from the side surface.
[0024]
Furthermore, the insertion part 6 of the self-luminous body a having the luminous property forms notches 8 formed by notching inwardly from the hook 7 at predetermined intervals. A plurality of the notches 8 are formed as shown in FIG. These notches 8 are smoothly inserted into the holes 1 when they are slightly pressed and narrowed with fingers, and when the light-emitting / emitting portions 4 are slightly pressed, the hooks 7 fly away from the back surface 3 of the panel b. Because of the protruding hook shape, it catches and locks on the back surface portion 3 and does not easily come off.
[0025]
The insertion portion 6 of the self-luminous body a has a slight thickness (about 1 mm) and has an inner portion formed in a hollow shape.
[0026]
Furthermore, the self-luminous body a has a circular shape when viewed from above, the accumulator 4, the insertion part 6, and the hook 7. As described above, the present invention is generally circular when viewed from above, but is not limited thereto.
[0027]
Further, in the present invention, a retroreflective sheet c that can be visually recognized by retroreflection, which will be described in detail below, is attached to the surface portion 2 of the panel b. After the sheet c is stuck on the entire surface or part of the panel b, the self-luminous body a is inserted into the hole 1.
[0028]
The self-luminous body a of the present invention is inserted so as to emit light to various characters and pictures using the hole 1 of the panel b as shown in the drawings. The light emission color of the illuminant a is dark white green. However, they may be used in combination with other self-luminous colors such as blue and orange.
[0029]
The manufacturing method of the self-luminous body a of the present invention is as follows.
[0030]
Synthetic resins used include polyolefin, polypropylene, polyethylene, polystyrene, polyethylene terephthalate, polystyrene, polyvinyl chloride, ABS, polymethyl methacrylate, polyacrylate, polycarbonate, polyamide, thermoplastic polyester, recycled PET bottles, etc. It is.
[0031]
Furthermore, it is a mixture comprising the above-mentioned various synthetic resins, inorganic phosphorescent pigments, colored pigments, and additives such as oil. The ratio of the luminous pigment is comprised in the range of 5-100 weight part with respect to 100 weight part of synthetic resins. And after mixing the said synthetic resin, an inorganic fluorescent pigment, a color pigment, and a trace amount additive with a blender etc. to obtain a blended product, the said blended product is heat-processed, on two mixing rollers, or a kneading extruder. Or, using a normal plastic kneader such as a Banbury mixer, it is pelletized into a cylindrical shape after homogeneous kneading.
[0032]
Further, the kneaded pellet composition is formed by various forming methods. For example, there are molding methods such as normal pressure molding, pressure molding, injection molding, extrusion molding, calendar molding, and the like, which can be carried out by one or a combination of two or more thereof.
[0033]
The self-luminous body a manufactured as described above has a function of storing the ultraviolet rays of sunlight during the day as energy and allowing the light to be seen and emitted by light in the dark at night by containing a coloring pigment and a phosphorescent pigment. To do.
[0034]
That is, the relationship between the colored pigment and the ultraviolet rays of sunlight that causes phosphorescent colored light emission is that the ultraviolet rays excite energy in the phosphor phosphor color material and store the light, so that the self-luminous body a is pale yellowish white during the day, It is completely unknown what color the phosphorescent component contained in the light-emitting body a emits. And at night, because the self-luminous body a having a luminous property composed of an inorganic pigment that accumulates light during the day and spontaneously emits light, it can be visually recognized by highlighting the darkness in multiple colors with polka dots. It is possible to produce colors according to the purpose. The action of making this polka dot pattern stand out in multiple colors depends on the characteristics of the reflection sheet c.
[0035]
Furthermore, the luminous intensity of the self-luminous material a has an afterglow characteristic of 2,000 minutes, which is 10 times the afterglow time of a conventional phosphorescent pigment, and the wavelength of light to be excited is 200 to 400 nanometers. Because of its large size, it has the property of shining all night long (Figs. 5 and 7).
[0036]
In addition, since phosphorescent pigments are fired by adding rare earth element activators with aluminate compounds as the main component, conventional phosphorescent pigments with zinc sulfide as the main component have low afterglow brightness and are harmful. Although it has a radioactive substance, the phosphorescent pigment implemented in the present invention does not contain any radioactive substance or harmful substance in addition to the long afterglow characteristic, so that environmentally friendly characteristics can be obtained.
[0037]
Furthermore, since the phosphorescent pigment implemented in the present invention is an oxide mainly composed of alumina, light absorption-emission-absorption-emission can be repeated semipermanently, and exhibits stable light resistance in nature. .
[0038]
FIG. 5 is an experimental comparison of afterglow characteristics of the aluminate compound phosphorescent material G300M employed in the invention and conventional night light.
[0039]
The retroreflective sheet c (FIG. 6) has the following configuration.
[0040]
Retroreflection is a reflection phenomenon in which incident light returns to the incident direction again by a special optical reflection mechanism.
[0041]
The reflective sheet of the present invention has improved visibility from the direction of the light source by retroreflection, and the object itself does not emit light like a phosphorescent pigment, and it is excited by light and fluoresces like a phosphor. It has different characteristics from those that emit.
[0042]
Structurally, a large number of fine high refractive index glass beads 9 having a diameter of 40 to 90 μm acting as a lens are uniformly arranged in the binding resin so as to satisfy a certain effect, and the total thickness is 100 to 100 μm. 200 μm thin and flexible sheet.
[0043]
Each glass bead 9 is a perfect round sphere and acts as a kind of convex lens. The incident light passes through the glass body beads 9 and is refracted to focus on one point. A light reflecting layer 10 such as metal is provided at the focus, and again passes through the glass beads 9 and is returned to the original light source direction. .
[0044]
The retroreflective sheet is “encapsulated lens type” in which glass beads 9 are encapsulated in a resin, “capsule lens type” in which glass beads are encapsulated in a small capsule together with air, and remains exposed in the air. Although it is roughly divided into three types of “exposed lens type”, the pressure-sensitive adhesive adhesive type of “encapsulated lens type” is used for the reflective sheet c that is used by being attached to the panel b of the present invention. Because it is used, it has a durability of more than 10 years when used outdoors in vertical exposure, and is the same as that used for road signs.
[0045]
Seven colors are available: white, yellow, red, orange, blue, green, and brown.
[0046]
11 is a surface film, 12 is a binder provided below the glass beads 9, and 13 is an adhesive, and a release paper 14 is peeled and attached to the bottom.
[0047]
The retroreflective sheet c has a thickness of about 0.18 mm.
[0048]
In the present invention, the retroreflective sheet c is adhered to the surface portion 2 of the panel b as follows.
[0049]
By dew blowing on the surface portion 2 of the panel b, and pressure-bonding with a spatula or a roller, the generation of bubbles is prevented.
[0050]
Furthermore, a pattern paper on which a predetermined character or pattern is drawn is temporarily pasted on the surface of the retroreflective sheet c. Then, a punch is pressed into the hole 1 in the range of the pattern paper to make a hole. In this case, do not hit the punch with a hammer or a mallet.
[0051]
When the hole is opened as described above, the self-luminous body a is inserted into the hole 1. And after insertion, a white paint is applied to the back surface of the self-luminous body a to enhance the self-luminous function.
[0052]
Furthermore, when a paint containing an ultraviolet absorber is used, the self-luminous function effect is remarkably enhanced.
[0053]
In the case where the self-luminous body a is a so-called colored character or pattern that is not made of a synthetic resin containing the above-described inorganic coloring pigment and phosphorescent pigment, it is formed in a polka dot pattern. However, because the self-luminous material a of the present invention is a synthetic resin having the above-mentioned inorganic coloring pigment and phosphorescent pigment, it is light green or light blue-green during the daytime (at the time of visible light). When ultraviolet light is stored, it is visible at night and in the dark because it emits phosphorescent light.
[0054]
However, the colored bodies constituting characters and patterns made of so-called general materials that do not emit light do not emit light at night or in the dark, and therefore cannot be visually recognized unless a means of lighting up is taken.
[0055]
Furthermore, a coating material is applied to the surface portion 2 of the panel b, or a silk printing or a marking film with a fluorescent coating is applied to make the self-luminous body a appearing as a polka dot pattern clear.
[0056]
In addition, each material itself applied, printed, or stuck as described above cannot be visually recognized at night because it does not have a phosphorescent function.
[0057]
However, with the self-luminous body a, the image that looks like a polka dot during the day also changes to a silhouette at night.
[0058]
The vehicle at the time of night driving, etc. on a guide sign such as a traffic sign board or a guide board formed by sticking the retroreflective sheet c on the surface portion 2 of the panel b and inserting the light-emitting body a into the hole portion 1 When the headlight hits, a predetermined sign character or the like formed by the self-light-emitting body a can be visually recognized as the light is retroreflected on the sheet c and lifted up more clearly, which is useful for preventing traffic accidents. .
[0059]
Furthermore, since the protruding light-emitting and light-emitting portion 4 of the self-luminous body a of the present invention is circular when viewed from the plane and curved when viewed from the side, the surface area is larger than that of the flat surface. It is remarkably large and has a large luminous function. Therefore, the light emitting function is not deteriorated for a long time.
[0060]
Furthermore, even if the panel b, which is the main part of the present invention, is fixedly installed, the self-luminous body a is detachable, so after using it for a certain period of time, if you want to make separate letters and designs according to your preference, The self-luminous body a may be removed and inserted. Therefore, it is not necessary to remove all the panels b that have already been installed, they are installed as they are, the self-luminous body a and the reflective sheet c that are being inserted are detached, and again according to predetermined characters and patterns. If the retroreflective sheet c is attached and the self-luminous body a is inserted into the hole 1 of the panel b, resources can be effectively used.
[0061]
