Description

  The present invention relates to a sign with a solar guide light, and more particularly to a sign that can be illuminated by a light emitting diode.

  In order to make it easy to visually recognize signs and marks on signboards installed outdoors such as traffic signs and billboards even when the surroundings are dim, such as at night, signboards equipped with lighting devices are known. Although this illuminating device requires electric power for illumination, the form which accumulate | stores electric power in the daytime using a solar cell, and makes an illuminating device light-emit with this electric power is also disclosed.

  For example, FIG. 4 shows an external view of a solar self-lighting traffic sign of Patent Document 1, and FIG. 5 shows an external side view thereof. The solar self-lighting traffic sign 800 of FIGS. 4 and 5 includes a traffic sign display unit 812 provided with an energy receiving plate 810 that exposes the light receiving surface 801a of the solar cell 801 to the outside, and a light emitting lamp 811. The sign body 820 is combined. Then, electric energy from the solar cell 801 of the energy receiving plate 810 is accumulated in a large-capacity power capacitor, and this electric energy is raised to a level necessary for driving the light emitting lamp 811 serving as a load to light the light emitting lamp 811. It is like that. As a result, the electric energy generated by the solar cell in the daytime can be stored with a large-capacity power capacitor, and this stored electric energy can be boosted at night and supplied to the light-emitting lamp to drive the lamp. This eliminates the need for a power source such as a battery, thus saving energy.

  However, the energy receiving plate 810 composed of the solar cell 801 is limited to only a practical role for producing electric power to the lighting device. Therefore, as shown in FIG. 4 and FIG. There is no design consistency with the display unit 8012. In addition, in order to increase the amount of light received from the sun, it is necessary to increase the bulk of the energy receiving plate 810. In that case, the energy receiving plate 810 floats more unnaturally and the design of the entire traffic sign is impaired. there were. In particular, the solar cells have almost the same shape and color, and are inclined at a certain angle and fixed at the highest position in order to receive sunlight efficiently. For this reason, since the shape, color, size, and posture are all the same, it can be determined that the solar cell is a glance. In other words, since they all exist in the same form, the fact is that they are very conspicuous and are lacking in design-like collectives. For this reason, in terms of design, disposing the solar cell significantly impairs the design.

Japanese Patent Laid-Open No. 6-348211

  The present invention has been made to solve the conventional problems. That is, the main object of the present invention is to provide a sign with a solar type guide light that is excellent in design regardless of the size of the solar cell module.

  The sign with a solar-type guide light of the present invention is a sign having a solar-type guide light that can illuminate the posted content using electric energy converted from solar radiation energy. The solar guide light sign is fixed to the solar cell module body 1 in which a plurality of solar cells 11 are arranged, a support body 2 that is fixed to the ground plane L and supports the solar cell module body, and the support body 2. A sign display body 3 and an illumination unit 9 fixed to the sign display body 3 and capable of illuminating the contents displayed on the sign display body 3 are provided. A panel fixing body 4 having a hue similar to that of the solar cell module body is fixed to the upper end of the support 2 opposite to the ground plane L. The solar cell module body 1 is surrounded by the panel fixing body 4. It is characterized by being arranged in this panel fixing body 4 so as to be surrounded by. Thereby, the solar cell module body 1 is arrange | positioned by using the panel fixing main body 4 similar to the hue of this solar cell module body 1 as a background color. As a result, the solar cell module body 1 and the panel fixing body 4 can be visually recognized in a series of substantially similar colors in the front view of the solar-type guide light-equipped sign 100, and are substantially integrated in color. That is, the solar cell module body 1 can be adapted to the background color of the panel fixing body 4 to reduce the presence of the solar cell module body 1 and the design is improved.

  In addition to the above features, the panel fixing body 4 may be formed to resemble a plant head flower, the support 2 may be colored green, and the sign display body 3 may have a leaf shape. Thereby, the sign with a solar type guide light upright from the ground surface can be imitated on the state of a plant extending from the ground to enhance the design.

  Further, the panel fixing body 4 is imitated by a sunflower head flower, and the panel fixing body 4 is disposed inside the petal imitation part 5 and the petal imitation part 5 as seen from the yellow tongue flower of the sunflower. It has a dark-colored inner board part 6 formed to imitate a sunflower tubular flower, and the solar cell module body 1 can also be fixed to the inner board part 6. As a result, the state in which the solar cells 11 are arranged in a planar shape can be imitated by a sunflower tubular flower, and the solar cell module 1 can be exposed without a sense of incongruity.

  Moreover, the sign with a solar guide light can be arranged such that the illumination unit 9 is at the upper part of the sign display body 3 and the light emitted from the illumination unit 9 travels substantially downward. Thereby, in addition to the illumination unit illuminating the sign display main body and making it easy to visually recognize the posted content, the light emitted from the illumination unit illuminates the feet, thereby also serving as a street lamp.

  Furthermore, the illumination part 9 can be comprised from several light emitting diode 9a. Light-emitting diodes can emit bright colors efficiently with low power consumption. Also, it is robust and has a long service life without worrying about ball breakage. Furthermore, it has excellent initial drive characteristics and is resistant to repeated vibrations and ON / OFF lighting, and is therefore suitable for outdoor use.

  Moreover, the sign with a solar type guide light can also cover the circumference | surroundings of the sign display main body 3 with the protection part 10 by an elastic body. Thereby, even if a user should be in contact with the sign display main body, the protective part can serve as a cushioning material, and the impact caused by the contact can be reduced.

  The panel fixing body 4 may be inclined with respect to the axial direction of the support 2 so that the light receiving surface 11a of the solar cell 11 and the support 2 form an acute angle. Thereby, the light-receiving surface 11a of the solar cell 11 can receive solar energy efficiently.

  In the sign with a solar type guide light, the charging mechanism 7 capable of storing electric energy from the solar cell 11 of the solar cell module body 1, the optical sensor 8 capable of sensing ambient illuminance, and the illuminance by the optical sensor 8 are predetermined. It can also have a control unit 12 that transmits electrical energy stored in the charging mechanism 7 to the illumination unit 9 when the level is lowered. Thereby, when the periphery of the sign with a solar type guide light becomes dim, the illumination unit can be automatically turned on.

  If it is a sign with a solar type guide light of the present invention, it can be made robust, and in addition to excellent functionality that can save maintenance, the design can be remarkably improved. In particular, by imitating a solar-type sign with a guide light in the shape of a plant, the appearance can be adjusted to the outdoor installation environment regardless of the size of the solar cell module body.

The front view of the sign with a solar type guide light of an Example is shown. The side view of the sign with a solar type guide light of an Example is shown. The block diagram in the electric system of the sign with a solar type guide light of an Example is shown. The external appearance perspective view of the conventional solar self-lighting type traffic sign is shown. The external appearance side view of FIG. 4 is shown.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the embodiment described below exemplifies a sign with a solar type guide light for embodying the technical idea of the present invention, and the present invention uses the following sign with a solar type guide light. Not specified. In addition, the member shown by the claim is not what specifies the member of embodiment. In particular, the dimensions, materials, shapes, relative arrangements, and the like of the constituent members described in the embodiments are not intended to limit the scope of the present invention only to the description unless otherwise specified. It is just an example. Note that the size, positional relationship, and the like of the members shown in each drawing may be exaggerated for clarity of explanation. Furthermore, in the following description, the same name and symbol indicate the same or the same members, and detailed description thereof will be omitted as appropriate. Furthermore, each element constituting the present invention may be configured such that a plurality of elements are constituted by the same member and the plurality of elements are shared by one member, and conversely, the function of one member is constituted by a plurality of members. It can also be realized by sharing. In addition, the contents described in some examples and embodiments may be used in other examples and embodiments.

  FIG. 1 shows a front view of a sign with a solar type guide light of the embodiment, and FIG. 2 shows a side view thereof. 1 and 2 is a solar-type guidance that can illuminate the posted content using electric energy converted from solar radiation energy. A sign with a light. The sign 100 includes a solar cell module body 1 in which a plurality of solar cells 11 are arranged, a support body 2 that is fixed to the ground plane L and supports the solar cell module body 1, and a sign display that is fixed to the support body 2. A main body 3 is provided. The sign display main body 3 has a sign display section 3a for displaying posted contents on the outer surface.

  Furthermore, the solar-type sign with guide light 100 includes an illumination unit 9 that is fixed to the sign display body 3 and illuminates the posted contents of the sign display body 3. The illumination unit 9 is automatically turned on or off according to the illuminance of the environment where the sign 100 is installed. The illumination unit 9 can use a fluorescent lamp or an incandescent lamp in addition to a light emitting diode. The illumination part 9 of an Example is an illumination unit comprised from the some light emitting diode 9a, and can be made into low power consumption by employ | adopting a light emitting diode. In addition, the light-emitting diode has almost no fear of running out of balls, which is advantageous for maintenance-free. The illumination unit 9 including the light emitting diode 9a can be a dielectric lamp that can display the posted content of the sign display body 3 with sufficient brightness even when the power is low or the power feeding circuit is stopped. Moreover, since the light emitting diode is small, it is preferable because the arrangement area of the illumination unit 9 in the sign display main body 3 can be reduced while the area of the sign display unit 3a can be gained.

  The illumination unit 9 is arranged in one or a plurality of rows on a part of the outer surface of the sign display main body 3 along the horizontal direction, the substantially vertical direction, or along the outer shape of the sign display main body 3, and irradiates the sign display unit 3a. The illuminating unit 9 in FIGS. 1 and 2 is arranged at an upper portion of the sign display main body 3 and arranged in a substantially horizontal posture so that light emitted from the illuminating unit 9 travels in a substantially downward direction. It can be used not only for lighting the main body but also for streetlights. In particular, in an example in which a light emitting diode is used as a light source, since the directivity of emitted light is high, it is preferable to adjust the light irradiation angle α by the illumination unit 9 to 30 ° to 90 °, and further to about 60 °. preferable. When the irradiation angle is smaller than 30 °, the spot area of light reaching the ground plane L becomes small, and the irradiation range becomes narrow. On the other hand, when the irradiation angle exceeds 90 °, the amount of light that can irradiate the ground plane L is reduced because the diffusion of light in the lateral direction is large, and the role of a street lamp cannot be fulfilled. Therefore, it is preferable to set the irradiation angle within the above range in consideration of the range to be irradiated and the illuminance. Note that the irradiation angle α of the illumination unit 9 indicates the irradiation angle of the emitted light from each light source constituting the illumination unit 9 as shown in FIG.

  Further, as described above, the illumination unit 9 is automatically turned on or off according to the illuminance of the environment where the sign 100 is installed. Specifically, the illumination unit 9 is turned off under a certain brightness such as during sunshine, and the illumination unit 9 is turned on when the surroundings are dark before and after sunset or at night. Hereinafter, a mechanism in which the illumination unit 9 is turned on or off depending on ambient illuminance will be described. FIG. 3 is a block diagram of the electric system of the sign 100 with the solar guide light according to the present invention. When the illuminance is reduced to a predetermined level by the charging mechanism 7 capable of storing electrical energy from the solar cell 11 of the solar cell module body 1 and the optical sensor 8 capable of sensing the ambient illuminance, the sign 100 is charged in the charging mechanism 7. And a control unit 12 capable of controlling the supplied electric energy to be supplied to the illumination unit 9.

  The solar cell module body 1 is a member that receives solar radiant energy, and refers to a panel shape in which a plurality of solar cells 11 are connected to obtain voltage and current. Moreover, you may use the solar cell array installed so that the required electric power could be obtained by connecting the some solar cell module body 1 further in series and parallel. As the solar cell 11, a known one can be adopted as long as it directly converts light energy into electric power, and a single crystal silicon solar was used in the examples. The solar cell 11 converts the received radiant energy into electric power by the photovoltaic effect and outputs it to the charging mechanism 7.

  The charging mechanism 7 can store electric energy such as a capacitor and a secondary battery. In the examples, an electric double layer capacitor was employed to increase the storage efficiency while reducing deterioration due to charge and discharge.

  The optical sensor 8 detects electromagnetic energy of light and can sense ambient illuminance. A photodiode, CdS, or the like can be used for such an optical sensor. When the control unit 12 detects that the ambient illuminance has decreased to a predetermined value by the optical sensor 8, the control unit 12 controls to supply the electric energy stored in the charging mechanism 7 to the illumination unit 9. Thereby, the illumination part 9 lights. On the other hand, when the control unit 12 detects that the ambient illuminance has increased to a predetermined value by the optical sensor 8, the control unit 12 stops the supply of electric energy from the charging mechanism 7 to the illumination unit 9. As a result, the illumination unit 9 is automatically turned on in an environment where it is difficult to visually recognize the sign display body 3 such as at night when the surroundings are dark. . In other words, the illumination unit 9 can be automatically turned on / off as necessary, so that unnecessary electric energy can be saved and the load on the environment can be reduced.

  However, the solar-type sign with guide light 100 may be equipped with means capable of detecting the output amount from the solar cell 11 as a substitute for the optical sensor 8. In this case, the control unit 12 determines that the sunshine has been reduced because the output amount from the solar cell 11 has decreased to a predetermined value, and starts supplying power from the charging mechanism 7 to the illumination unit 9. . Thereby, the brightness of the illumination can be adjusted according to the illuminance of the surrounding environment.

(Creativity)
In addition, the solar-type sign with guide light 100 fixes the panel fixing body 4 having a hue similar to the hue of the solar cell module body to the upper end of the support 2 opposite to the ground surface. In the front view of the sign 100, the solar cell module body 1 is arranged on the panel fixing body 4 so that the periphery is surrounded by the panel fixing body 4, so that the solar cell module body 1 and the panel fixing body 4 are hued. Therefore, the presence of the solar cell module body 1 can be made inconspicuous.

  Furthermore, the design 100 can be enhanced by imitating the sign 100 with a solar type guide light in the shape of a plant. As shown in FIG. 1, the sign 100 may be formed by imitating the panel fixing body 4 like a head flower of a plant. Moreover, the support body 2 can be made into the shape of a column upright in the vertical direction, resembling a stem, and can be colored green. The sign display body 3 can be configured in the shape of a leaf. More specifically, the panel fixing body 4 is similar in shape to the head flower of the sunflower, and the petal imitation part 5 is seen as a yellow tongue flower of the sunflower, and the tubular imprinting part 5 is arranged inside the petal imitation part 5. And a dark-colored inner board portion 6 formed to resemble a flower. And the solar cell module body 1 is fixed to the inner board part 6 formed to imitate the sunflower tubular flower, so that the solar cells 11 are arranged in a matrix and located inside the sunflower head flower. It is possible to resemble the appearance of numerous and small tubular flowers. As a result, the appearance of the solar cell module body 1 can be adapted to the characteristics of the sunflower, and the solar cell module body 1 can be incorporated into the sign 100 without a sense of incongruity.

  In addition, the solar-guided sign 100 imitated by a plant is easy to harmonize with the environment, and the appearance of standing upright from the ground contact surface L matches the habits of the actual plant, and the design is interesting. In addition, the substrate body having the control unit 12 described above is disposed on the inner panel portion 6, more specifically, on the back side of the solar cell module body 1, so that the design can be further enhanced while reducing the exposure of the substrate body. it can. In the embodiment, an integrated control box in which the solar cell 11 and the control unit 12 are integrated is adopted, and the number of parts is reduced to simplify the assembly.

  Further, the solar cell module body 1 is fixed to the inner panel portion 6 by looking at the solar-type sign with a guide light, and the sign 100 can be installed without a sense of incongruity regardless of the size of the solar cell module body 1. This is because it is well known that sunflowers generally produce large flowers. Therefore, the surface area of the solar cell module 1 is increased in order to improve the light collection rate, and as a result, a panel corresponding to the head flower part of the sunflower. This is because even if the fixed main body 4 is enlarged as a whole, the balance with the support 2 corresponding to the stem of the sunflower approximates the actual sunflower. Therefore, regardless of the size of the solar cell module body 1, it is possible to obtain the solar guide light sign 100 with excellent design, and the number of solar cells 11 can be increased to increase the amount of received light.

  Further, as shown in FIG. 2, the panel fixing body 4 may be inclined with respect to the axial direction of the support 2 so that the light receiving surface 11a of the solar cell 11 and the support 2 form an acute angle. Thus, the solar cell 11 can efficiently receive solar energy. In particular, when the sign 100 with a solar type guide light is seen on a sunflower, the position of the head flower heading up to the sky due to the inclination of the panel fixing body 4 means “sunflower” when the sunflower is marked in Chinese characters. Because it matches the state of "flowers facing the sun", it can be a sign with a solar-type guide light that is not only practical but also interesting. In other words, the image of a sign that receives a lot of sunlight and stores electrical energy matches that of “Sunflower”, and it leads to appealing to consumers as a sign that generates electricity with sunlight during installation and installation.

  Further, the sign display body 3 in FIG. 1 has a shape imitating a sunflower leaf. Specifically, the sign display main body 3 has a heart shape, and the outer shape of the sign display main body 3 is configured to intersect at a lower central portion while being curved from both ends of a straight line extending in the horizontal direction at the upper portion. In particular, by making the upper portion of the sign display body 3 a horizontal straight line, the lighting unit 9 can be installed substantially in parallel along the straight line portion, and the arrangement of the lighting unit 9 can be made inconspicuous. The sign display body 3 is fixed in the middle of both ends of the support 2. The support body 2 having the lower end fixed to the grounding surface L supports the panel fixing body 4 at the upper end, and the sign display body 3 is in contact with the height from the grounding surface L to the panel fixing body 4 as a reference. It is preferable to fix at a position of 50% to 90% from the ground L, whereby the visibility of the sign display portion 3a can be improved.

  In the embodiment, the arrangement of the solar cells 11 is seen as a sunflower. However, the present invention is not limited to this, and the solar cell module body 1 can be incorporated into some of various characters. For example, it can be combined with a part of the shape of an animal, an insect, a dinosaur, a vehicle, a monster, etc. in addition to a character's costume, for example, a cloak, glasses, a helmet of a warlord. For example, an integrated design can be obtained by incorporating the solar cell module body 1 into a symbolic symbol such as a dragonfly blade. Moreover, the form which makes the solar cell module body 1 plural may be sufficient.

  Further, the periphery of the sign display main body 3 can be covered with a protection unit 10 made of an elastic body, so that the impact property with the objective in the event of dropping or the like can be reduced.

  The sign display body 3 can be colored in a color resembling a plant, for example, in green, like the support 2 resembling a stem. In particular, when a bright color with improved visibility is used for the sign display section 3a, the sign display body 3 that is green is preferable because it can be a background color with increased color contrast with the sign display section 3a. The sign display unit 3a is preferably made of a highly resistant material in consideration of outdoor use, and for example, a reflective paint can be employed. The reflective paint is composed of a highly transparent paint and a reflective sphere, and even in an environment where the ambient illuminance is low, the reflective sphere on the coating surface reflects the light from the illumination unit 9 to improve visibility. .

  As described above, the sign with solar guide light 100 can reduce power consumption while omitting the installation of an external power source, and can be a sign having a good design. In addition, a stand-alone sign that can be driven by self-power generation without a commercial power source can be realized, which is suitable for installation in mountainous areas.

  The sign with a solar type guide light of the present invention can be suitably used for traffic signs, evacuation guide lights, signboards and the like.
