Modes for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the embodiments described below do not unduly limit the content of the present invention described in the claims. Also, not all of the components shown in the embodiments are essential components of the present invention.

[0011] <Configuration> FIG. 1 is a diagram for explaining an example of a light-emitting unit according to a first embodiment of the present invention.

[0012] In the present embodiment, the light-emitting unit 10 is a unit applicable to locations such as outdoor facilities, mountain trails, and trail running where it cannot be attached to the ground. As shown in FIG. 1(a), it is composed of a display unit 11 and a fixing unit 12. The fixing unit 12 is a pile-shaped structure, and its lower part has a sharp structure so that it can be independently fixed to the ground and can be driven into the ground. As the fixing unit 12, a resin material can be used for the pile, and in addition to resin, wood or the like can also be used. Thereby, when it deteriorates over time, it is possible to repeatedly use the energy storage light-emitting unit by refilling only the pile part. As shown in FIG. 1(b), the display unit 11 is coated with an energy storage paint, emits light at night, and is designed to guide the direction and current location so as to be able to guide pedestrians. An energy storage material, a reflective material, or a fluorescent material is attached, coated, or printed. Here, as the color development of the energy storage, by using blue, blue-green, or green, it is possible to maintain a high brightness with high afterglow properties, weather resistance, and durability. On the other hand, in outdoor facilities such as campsites and facilities mainly made of wood, white, light bulb color, and warm color developments are often desired due to their attributes. However, if a coloring pigment or dye is contained in the energy storage material to change the color, the brightness may be significantly reduced. For example, when it is red, the brightness is about one-tenth of that of blue energy storage. Therefore, by processing a transparent colored film or a transmissive print on the energy storage material with the highest brightness of blue color development, or by applying a transmissive paint, it is possible to perform processing according to the wishes of the operators of each facility while maintaining the high brightness. Thereby, the safety of users at night can be realized while maintaining the designability of the space. According to the present embodiment, even on a mountain trail without unevenness and on the ground where it is difficult to attach a light-emitting unit as in the first embodiment, a light-emitting unit capable of guiding pedestrians can be applied.

[0013] 2 is a diagram illustrating another example of a light-emitting unit display unit according to the first embodiment of the present invention. As shown in FIG. 2(a), the display unit 11 of the light-emitting unit 10, i.e., the top of the light-emitting unit 10, can be cylindrical, hemispherical as shown in FIG. 2(b), or any other polygonal three-dimensional shape, and can have any shape that allows for design. Furthermore, by applying reflective lines to the display unit 11 (top), it is possible to ensure pedestrian safety. By applying a geometric pattern such as diagonal lines, or a universal design such as a picture or pictogram, it is possible to guide pedestrians and improve the design. Furthermore, by adding a QR code (registered trademark) that can access location information, it is possible to provide necessary information to pedestrians.

[0014] FIG. 3 is a diagram illustrating an example of a method for installing a light-emitting unit according to a first embodiment of the present invention. FIG. 3 illustrates an example in which light-emitting units are installed on both sides of an unpaved sidewalk at an outdoor facility. In outdoor facilities such as campgrounds, the lack of lighting makes the road dark at night, posing a safety hazard for pedestrians. Since sidewalks are typically made of earth, multiple light-emitting units 10 are installed at any location on the sidewalk by fastening the fixing parts 12 (in this example, stakes) of the light-emitting units 10 to the soil. When light-emitting units 10 were actually installed on a sidewalk at a campground, mud was observed to adhere to the display parts 11 (tops) and fixing parts 12 of the light-emitting units 10 exposed to the ground due to pedestrian footfall or rain. Here, in addition to applying a top coat to the light-emitting units 10, the luminous surfaces and the entire stakes were coated with a urethane-based or silicone-based resin paint that repels dirt and adhesive components, preventing dirt and grime from adhering and allowing the dirt to wash off with rain or other factors. Furthermore, when the light-emitting unit 10 is fixed to the ground, there is a concern that the light-emitting unit 10 may become dislodged. To prevent this, the light-emitting unit 10 can be secured to the ground by the fixing portion 12 (e.g., a body such as a stake) and then further secured to the ground by concrete, gravel, or black soil. This prevents the light-emitting unit 10 from easily becoming dislodged from the ground. More specifically, if the stake is buried in a location with a large amount of gravel or pebbles in the soil, the presence of air pockets reduces the soil density, preventing the ground from applying sufficient pressure to secure the unit, potentially causing the unit to become dislodged with even a small amount of force. Therefore, during construction, the process of digging the soil, removing the pebbles, adding black soil, adding water, and then increasing the density and solidifying the soil can be repeated to ensure a stable installation of the unit in the buried ground. Furthermore, the fixation can be strengthened by inserting one or more metal screws into the side of the stake.

[0015] FIG. 4 is a diagram for explaining another example of the light-emitting unit according to the first embodiment of the present invention. In the above-described embodiment, the light-emitting unit 10 having a structure in which the display unit 11 and the fixing unit 12 are integrated was exemplified. However, as in this example, only the display unit 11 (for example, the top of the head) can be independently used as the light-emitting unit 10.

[0016] As shown in FIG. 4, the light-emitting unit 10 can be installed by tilting a cube while being conscious of the pedestrian's viewing angle, and information can be transmitted on a plurality of surfaces. As shown in FIG. 4(a), the light-emitting unit 10 can be installed at a branch point of a passage to display the information after branching (stairs and destination distance), respectively. Also, as shown in FIG. 4(b), the current location and a message (such as no smoking) can be displayed. Furthermore, it is also possible to transition to an area information site using a QR code (registered trademark) or the like. By connecting the light-emitting unit 10 to a structure such as a handrail or a wall surface with a fixture 15 such as a pole or a metal fitting, an effect can be achieved as if the light-emitting unit 10 is floating in the air, especially at night.

[0017] FIG. 4 is a diagram for explaining an application example of the light-emitting unit according to the first embodiment of the present invention to the handrail of an outdoor promenade. A plurality of the light-emitting units 10 shown in FIG. 4 are installed on the handrail 20 provided on an outdoor promenade without electric lights via a fixture 15 (by installing a fastener on the handrail post or the handrail and fixing a square pipe or an aluminum pipe to the fastener, and then fixing the light-emitting unit 10 to the square pipe or the aluminum pipe). Thus, guidance can be provided to pedestrians during dark hours such as at night, and information can be displayed to pedestrians by signs or the like displayed on the top of the head regardless of day or night. Also, as described above, by installing the light-emitting unit 10 via the fixture 13, an effect can be achieved such that the light-emitting unit 10 emits light at night and appears to be floating in the air. In addition, a plurality of the light-emitting units 10 of this example can be arranged on conductors in indoor areas (such as corridors, offices, wall surfaces, etc.) or emergency exits.

[0018] Although the embodiments according to the invention have been described above, they can be implemented in various other forms such as shape and materials used, and can be implemented with various omissions, substitutions, and changes. These embodiments, variations, and those with omissions, substitutions, and changes are included in the technical scope of the claims and the equivalent scope thereof.
