Description

  The present invention relates to an information sign body for marking a road sign such as a line-of-sight guidance with light from a light emitter.

  Conventionally, as this kind of information indicating body, the information indicating body includes an information indicating body having a storage portion therein, a light emitter stored in the storage portion, and a solar cell for supplying power to the light emitter. Is known in which a window portion for irradiating light from the light emitter stored in the storage portion to the outside is formed, and the window portion is provided with a translucent window plate. .

  Such an information sign forms characters or symbols to be marked by illuminating the illuminant using electric power generated by the solar cell, and passers-by or the like pass light from the illuminant. Recognize the sign by recognizing it.

  However, in the conventional information sign body described above, since the window plate provided in the window portion for irradiating the light from the light emitter to the outside is colorless and transparent, external light such as sunlight is exposed to the window plate. In addition, the transmitted light that external light has transmitted through the window plate is strongly reflected by the light emitter, and the transmitted light may be irregularly reflected between the window plate and the light emitter in the storage unit. If it does so, the light from the light-emitting body emitted using the comparatively weak electric power from a solar cell will be reflected by the light reflected in a window board or a light-emitting body, or irregularly reflected between the window board and light-emitting body in a storage part. As a result, the passerby cannot recognize the sign formed by the light from the light emitter.

  Therefore, the present invention has been made in view of the above circumstances, and by reliably irradiating light from a light emitter, an information sign that allows a passerby or the like to reliably recognize a sign formed by light from the light emitter. The challenge is to provide a body.

  The present invention has been made to solve the above-described problems, and an information sign according to the present invention includes an information sign main body having a storage portion therein, a light emitter stored in the storage portion, and the light emitter. A window for irradiating the light from the light emitter stored in the storage unit to the outside, and the window unit includes: A window plate having translucency is provided, and the window plate is colored.

  In the information sign body of the configuration, since the window plate having translucency is colored, reflection of the external light such as sunlight on the window plate can be suppressed. Since the transmittance of the external light is low and the transmission of the external light through the window plate can be suppressed, the reflection of the transmitted light transmitted through the window plate by the external light or between the window plate and the light emitting body. Diffuse reflection can be suppressed. Therefore, the light from the light emitter that is emitted using the power from the solar cell is reliably irradiated to the outside without being erased by the reflected or irregularly reflected light.

  As described above, in the information sign according to the present invention, since the window plate having translucency is colored, reflection of the external light on the window plate can be suppressed, and the external light can be suppressed. As a result of suppressing transmission through the window plate and suppressing reflection at the light emitter and diffuse reflection between the window plate and the light emitter, the light from the light emitter that is emitted using the power from the solar cell is reduced. Irradiation to the outside is surely performed without being erased, so that a passerby or the like can surely recognize the sign formed by the light from the light emitter.

Hereinafter, one embodiment of an information sign object concerning the present invention is described in detail, referring to drawings.
1A and 1B show an information sign 1 in the present embodiment. The information sign 1 is attached to a pillar P standing on a road so as to give various signs such as road traffic information and alerts to passersby.

  The information sign body 1 includes an information sign body 2 having a storage portion 6 therein, a light emitting unit 3 that is configured to be housed in the storage portion 6 of the information sign body 2 and includes a light emitter 7, and lighting of the light emitter 7. And a solar cell 5 that supplies power to the light emitter 7.

  The information marking main body 2 includes a main body portion 21 whose front surface is open and whose rear surface is closed, and a lid portion 22 that opens and closes the opening of the main body portion 21. The main body 21 is made of, for example, an aluminum alloy, and the rear surface side is configured to be attachable to the column P.

  The lid portion 22 has a front surface 22a closed and a rear surface 22b opened. Specifically, the inner region has a frame body 23 serving as a window portion 231 for irradiating light from the light emitter 7 to the outside. And a window plate 24 for closing the front side of the frame body 23. The lid 22 has a frame 23 attached to the main body 21 via a hinge so as to be rotatable, and opens and closes the front opening of the main body 21 by rotating about the hinge. A region surrounded by the main body 21 and the lid 22 (that is, the inside of the information sign main body 2) is the storage section 6. Further, the vertical and horizontal lengths of the lid portion 22 are slightly larger than the vertical and horizontal lengths of the main body portion 21.

  The frame body 23 is configured in a rectangular shape using, for example, an aluminum alloy, and a region surrounded by the frame body 23 is configured to be the window portion 231. The window plate 24 is a colored transparent plate having translucency, and has a light reflection preventing function and high resolution. Specifically, the transmittance of the window plate 24 is set to a predetermined value, for example, by coloring a synthetic resin plate. In the present embodiment, the window plate 24 is formed by performing brown smoke on a polycarbonate plate. Incidentally, for example, the transmittance of the colorless and transparent polycarbonate plate is 89.3%, while the transmittance of the polycarbonate plate subjected to brown smoke is 60.6%. Further, the window plate 24 is configured to close the entire window portion 231, that is, the window plate 24 has a shape corresponding to the inner shape of the frame body 23.

  As shown in FIG. 2, the light emitting unit 3 includes a light emitting substrate 31 on which a plurality of light emitters 7 are mounted on one surface 31a and a concave member 81 constituting the connector 8 is mounted on the other surface 31b, and one surface 32a. An electronic component (not shown) for controlling the lighting of the light-emitting body 7 is mounted, and a convex member 82 for electrical communication and mechanical connection with the concave member 81 is mounted on the other surface 32b. The control board 32 is provided. In the light emitting unit 3, the light emitting substrate 31 and the control substrate 32 face each other's other surfaces 31b and 32b, and connect the concave member 81 that is the connector 8 and the convex member 82 to electrically and mechanically connect. It is configured to be. The convex member 82 may be mounted on the light emitting substrate 31 and the concave member 81 may be mounted on the control substrate 32.

  The light emitting unit 3 is configured to be housed in the housing portion 6 of the information sign main body 2 and is configured to be attached to the inside of the frame body 23 of the lid portion 22 in the present embodiment. Specifically, the light emitting unit 3 is attached to the inside of the frame body 23 in a state where a predetermined gap is formed between the light emitting unit 3 and the window plate 24, and rotates as the lid portion 22 rotates. The light emitting unit 3 has a size corresponding to an area surrounded by the frame body 23 and is attached to the inside of the frame body 23 so as to cover the entire area.

The light emitter 7 is an LED 7 and is solder-mounted on the one surface 31 a so that the irradiation direction is perpendicular to the one surface 31 a of the light emitting substrate 31 and outward. Here, since the information sign 1 in the present embodiment is the information sign 1 of multicolor emission, a plurality of LEDs 7 are prepared, and a plurality of light emission colors are prepared. In addition, the number of LED7, luminescent color, and arrangement | positioning can be determined suitably as needed. In addition, the brightness | luminance of LED7 is illustrated in the following Table 1 for every luminescent color.

  The soldering operation for mounting the LED 7, the concave member 81, the convex member 82, and the electronic component can be performed by hand soldering, but it is more efficient and preferable to perform it automatically by a soldering machine. The light emitting substrate 31 on which the LED 7 and the concave member 81 are mounted and the control substrate 32 on which the electronic component and the convex member 82 are mounted are each subjected to a so-called moisture-proof coating treatment.

  The control unit 4 controls the lighting of the LED 7, and includes a controller 41 for setting and selecting a program for controlling the lighting, and a storage battery 42 for storing the power generated by the solar cell 5. Is provided. The control unit 4 is attached to the support column P so as to face the rear surface side of the information sign body 2 and is electrically connected to the light emitting unit 3. Specifically, the control unit 4 is electrically connected to an electronic component mounted on the one surface 32 a side of the control board 32, and thereby can supply power, a signal, and the like to the LED 7. In addition, as the storage battery 42, a lead storage battery can be used, for example.

  The solar cell 5 generates power using sunlight, and is configured to supply power to the LED 7 via the storage battery 42 of the control unit 4.

  In the information sign 1 having the above configuration, since the window plate 24 is a polycarbonate plate subjected to brown smoke, reflection of external light such as sunlight on the window plate 24 can be suppressed, Suppressing the transmission of the external light through the window plate 24 and suppressing the reflection of the transmitted light L3 transmitted by the external light through the window plate 24 at the light emitter 7 and the irregular reflection at the gap between the window plate 24 and the LED 7 are suppressed. it can.

  Referring to FIG. 2, the window plate 24 is subjected to brown smoke and has an antireflection function. Therefore, a part of the external light L1 irradiated to the window plate 24 is absorbed by the window plate 24. It is weakened and reflected. That is, the reflection of the external light L1 on the window plate 24 is suppressed, and the reflected light L2 becomes weak.

  Further, since the transmittance of the window plate 24 is reduced by brown smoke as compared with the case of being colorless and transparent, the amount of the external light L1 irradiated to the window plate 24 is reduced. That is, the transmission of the external light L1 through the window plate 24 is suppressed, and the transmitted light L3 becomes weak. If it does so, the reflected light L4 which the said transmitted light L3 reflected in LED7 will become weak, and the irregularly reflected light L5 which the said transmitted light L3 diffusely reflected in the clearance gap between the window plate 24 and LED7 will also become weak.

  As described above, the reflected light L2 of the external light L1 from the window plate 24, the reflected light L4 from the LED 7, and the irregularly reflected light L5 in the gap between the window plate 24 and the LED 7 are weak. The light LL emitted from the LED 7 using relatively weak power is reliably irradiated to the outside without being erased by the reflected light L2 and L4 or the irregularly reflected light L5. Therefore, a passerby etc. can recognize the sign formed with the light LL from LED7 reliably.

  Moreover, since it is brown smoke applied to the window plate 24, all the light of the plurality of LEDs 7 exhibiting various colors can be visually perceived through the window plate 24, and the indication is clearly recognized. it can.

  In this embodiment, the case where the window plate 24 is a polycarbonate plate subjected to brown smoke and the transmittance thereof is 60.6% has been described. However, the present invention is not limited to this, and for example, a polycarbonate plate subjected to gray smoke. In this case, the transmittance may be 55.1%. However, if the polycarbonate plate is subjected to grey-smoke, the transmittance with respect to light of a predetermined wavelength (for example, light with a wavelength of 500 nm to 700 nm) is particularly low, and the light of the predetermined wavelength out of the light emitted from the LED 7 is extremely visible. It may be difficult to recognize information indicated by the information sign 1. On the other hand, when the polycarbonate plate is subjected to brown smoke, there is an advantage that light from the LED 7 can be reliably recognized without such a fear.

  Further, in the present embodiment, the case where the information sign main body 2 is configured by rotatably attaching the lid portion 22 to the main body portion 21 has been described, but not limited thereto, the lid portion 22 is not limited to the main body portion 21. It may be a case where it is attached and fixed to the main body 21 so as to close the front opening.

It is a figure which shows one Embodiment of the information sign body which concerns on this invention, (A) is a front view, (B) is a side view. The expanded sectional view which shows the principal part of the same information sign body.
