  In many cases, the self-luminous line-of-sight guidance sign column has various directions in which visibility during light emission is required depending on the installation location.

  For example, there are various patterns such as not only when visibility from all 360 ° directions around the axis of the sign post body is required, but also when visibility from any one direction or a plurality of directions is sufficient.

  For this reason, for example, installing a marker column that emits light in all 360 ° directions in an installation location where visibility from only one direction is sufficient is necessary to drive light emitters that are not involved in visibility and those. There is a problem that power is wasted.

  For this problem, it is conceivable to install a sign post with specifications according to the visibility requirement for each installation location. However, as in the above prior art, a window part is provided on the sign post body or the pedestal part, In the configuration in which the light emitter is arranged in the circumferential direction of the surface or the unit having the light emitter is mounted in the hole portion of the pedestal portion, the marker column main body, the pedestal portion, and the light emitter unit having a structure according to the requirement for visibility are respectively It is necessary to prepare multiple types and select and replace them for each installation location.

  Therefore, it is necessary to prepare and prepare a multi-spec signpost body, a pedestal part, or a light emitting unit, and there are problems that the manufacturing cost is high and maintenance management is complicated.

  Focusing on the actual use state, the angle of the driver's line of sight with respect to the self-luminous line-of-sight guide sign column changes as the vehicle moves, so the light emitter is arranged to satisfy the improvement in visibility in a certain direction. Even so, it is desirable to be able to irradiate light in a wide angular range to some extent in the horizontal and vertical directions in order to improve the visibility from the moving driver.

  However, since the LED generally used as the light emitter is a point light source having strong directivity, there is a problem that visibility is extremely lowered when viewed from a direction other than the direction in which the light emitter is arranged.

  FIG. 15 is a plan view of a self-luminous line-of-sight guidance sign column in which a light emitter 102 that emits light in the four directions around the pedestal portion 100 described in Patent Document 2 is arranged.

  The light emitter 102 is provided in the unit 101 mounted in the hole of the pedestal unit 100. In this case, since the irradiation direction A, which is the optical axis of the light emitter 102, is directed in the four directions around the pedestal portion 100, it seems that the visibility is improved over a wide range of 360 ° at first glance. In other words, when viewed from an oblique direction B with respect to the irradiation direction A, the amount of light is greatly reduced and the visibility is lowered because it deviates from the optical axis of the light emitter 102. Therefore, the visibility when viewed from a moving driver is not always good.

  In this case, it is necessary to increase the number of light emitters 102 so that light emission in an oblique direction B is possible, but it is necessary to separately prepare and replace the unit 101 with the increased number of light emitters 102. Since it is necessary to prepare a plurality of types of units 101 having different light emitters 102, there is a problem that manufacturing costs are increased and maintenance management becomes complicated as described above.

  Therefore, an object of the present invention is to provide a self-luminous gaze guidance sign column that can easily deal with light emission in any direction with the same specifications and can ensure good visibility.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 is a perspective view showing an example of a self-luminous line-of-sight guide column according to the present invention, FIG. 2 is a bottom view of the pedestal portion thereof, and FIG. 3 is a sectional view taken along line (iii)-(iii) in FIG. .

  The self-luminous line-of-sight guidance sign post 1 (hereinafter simply referred to as the sign post 1) includes a pedestal part 2 and a sign post main body 3 made of a soft resin such as polyurethane and standing on the pedestal part 2. The pedestal 2 is installed on the road surface, for example.

  A circular wall portion 21 is formed on the upper surface of the pedestal portion 2. Inside the circular wall portion 21, there is a recess 21 a into which the lower end portion 31 of the marker pillar body 3 is inserted, and a sign at the center of the bottom of the recess 21 a. A bolt insertion hole 21 b is formed through which a mounting bolt 32 protruding from the lower end 31 of the column main body 3 is inserted.

  The mounting bolt 32 is screwed to an unillustrated embedment leg embedded in the road surface, whereby the sign post body 3 is erected on the pedestal portion 2.

  In the present embodiment, the planar circular pedestal portion 2 is described as an example, but the planar shape of the pedestal portion 2 is not particularly limited, and may be any shape such as an elliptical shape or a rectangular shape.

  Around the circular wall portion 21 of the pedestal portion 2, a top plate portion 2a is provided. The shape of the pedestal portion 2, particularly the top plate portion 2a is not particularly limited, and any shape such as a disc shape, an oval shape, a rectangular shape, etc. is preferable, but a disc shape is preferred. Hereinafter, the case of a disk shape will be described.

  The top plate portion 2a is formed of a translucent resin such as a transparent or translucent resin.

  A space 22 that opens downward is formed on the inner surface of the disk-shaped top plate portion 2a extending in the radial direction from the circular wall portion 21.

  For this reason, in order to reinforce the top plate portion 2a of the pedestal portion 2 which is substantially thin, a plurality of radiation ribs 23 extending radially from the circular wall portion 21 and the radiation ribs 23 are connected to the space 22. Thus, the circular wall portion 21 and one circular rib 24 provided concentrically are formed.

  In the present embodiment, of the radial ribs 23 and the circular ribs 24 formed in the space 22, at least one of the circular ribs 24 along the circumferential direction of the top plate portion 2 a of the pedestal portion 2 is directed toward the outer peripheral side. A light emitter 4 is arranged.

  The entirety of the light emitter 4 is disposed in the space 22 on the lower surface of the top plate portion 2 a and is not exposed on the outer surface of the top plate portion 2 a, that is, not exposed on the outer surface of the pedestal portion 2.

  Therefore, the light emitter 4 emits light from the inner surface of the pedestal 2 toward the outer surface. Since the entire light emitting body 4 is covered with the top plate portion 2a of the pedestal portion 2, the light emitting body 4 is not exposed to wind and rain, and the durability can be improved.

  In general, an LED is preferably used as the light emitter 4 from the viewpoint of low power and long life. Each light emitter 4 is electrically connected in series or in parallel by a power supply unit 5 similarly provided in the space 22 and a lead wire (not shown). Each radiation rib 23 located between the circular top plate portion 2a and the circular rib 24 is formed with a notch 23a for accommodating a lead wire (not shown).

  The power supply unit 5 includes a solar cell, a battery that stores electric power, an electronic substrate for driving the light emitter 4, and the like. The pedestal 2 is provided with a window 25 for exposing the solar cell 5a mounted on the power supply unit 5 to the outer surface. The power supply unit 5 is preferably sealed with a silicon gel or the like in the casing in order to improve water resistance.

  In FIG. 2, a total of 11 light emitter mounting portions 24 a are arranged in parallel so as to be substantially equally spaced on the circular ribs 24 separated by the radiation ribs 23 in the space 22 of the pedestal portion 2. The light emitters 4 are disposed on the light emitter attachment portions 24a.

  FIG. 2 shows an aspect in which the maximum number of 11 light emitters 4 are arranged along the circumferential direction of the pedestal portion 2 and the light from the light emitters 4 is irradiated over the entire circumference of 360 ° to achieve the highest luminance. Show.

  However, in the present invention, the light emitter 4 is detachably attached to the light emitter attachment portion 24a.

  By attaching an arbitrary number of the light emitters 4 to the light emitter attachment portion 24a at an arbitrary position, light emission with emphasis on any one direction or a plurality of directions can be performed. Details of this configuration will be described later.

  On the bottom surface side of the pedestal portion 2, a waterproof sheet 26 made of foamed rubber or the like for preventing water from entering the space 22, and a metal or resin for covering the bottom surface of the pedestal portion 2 from the outside thereof A bottom cover 27 made of metal is attached to each screw hole portion 28 formed in the pedestal portion 2 with a tapping screw 29 to protect the internal light emitter 4 and the power supply unit 5.

  The sign post 1 improves the visibility at night particularly when at least one light emitter 4 disposed in the space 22 inside the pedestal 2 emits light and blinks. It is preferably formed of a translucent resin (for example, a transparent or translucent resin) containing a diffusing material.

  The resin that can be used for the pedestal portion 2 can be a transparent or translucent resin that does not impede the transmission of light from the light-emitting body 4 disposed inside. Considering the durability, it is preferable to use a resin having high strength, and specifically, polycarbonate is preferable.

  Moreover, it is preferable to use a translucent fluorescent red resin for the pedestal portion 2 because the pedestal body itself has good visibility. In particular, when the light emitter 4 starts to light up, the lighting of the light emitter 4 is not noticeable, but the use of fluorescent red resin for the base body can improve the visibility of the base.

  The light diffusing material is added to the resin that forms the pedestal portion 2, thereby diffusing the light irradiated to a certain region of the pedestal portion 2 through a wide range through the pedestal portion 2 itself. As a result, the entire pedestal 2 is illuminated with the light emitter 4 as the center, and light is irradiated at a wide angle around. Therefore, even if the light emitter 4 is a point light source, good visibility can be ensured over a wide range in the circumferential direction of the pedestal portion 2.

  In FIG. 3, an arrow indicates that the light emitted from the light emitter 4 arranged in the space 22 to the inner surface side of the pedestal portion 2 is guided and diffused in the vertical direction through the pedestal portion 2 itself.

  Further, in FIG. 4, a state in which light is diffused in the horizontal direction is indicated by arrows. In (a), the light from the three adjacent light emitters 4 is irradiated on the inner surface side of the pedestal portion 2, so that the light is diffused in a wide range through the pedestal portion 2 itself.

  Due to the light diffusion effect of the pedestal 2, the amount of light is not greatly reduced even between the adjacent light emitters 4, and sufficient visibility can be ensured.

  On the other hand, in (b), the light emitter 4 is not attached to the light emitter mounting portion 24a between the two light emitters 4, but even in this case, the light quantity between the light emitters 4 is remarkably large due to the light diffusion effect of the pedestal portion 2. It does not decrease, and visibility can be ensured over a wide range.

  That is, according to this marker pillar 1, the light from the illuminant 4 is diffused over a wide range by guiding it through the pedestal 2 itself mixed with the light diffusing material, and the visibility over a wide range can be ensured. it can. Therefore, even if a minimum number of light emitters 4 are arranged to satisfy the visibility in only one direction, a wide range in the horizontal and vertical directions around the optical axis is provided. Thus, it is possible to irradiate light over a long period of time, and it is possible to ensure good visibility from a moving driver.

  In addition, the surface of the pedestal 2 main body mixed with the light diffusing material, in particular, the surface of the top plate 2a is processed to have a concave-convex shape so that the pedestal 2 looks more like surface emission and is visually recognized by the light diffusion effect. It is possible to improve the properties.

  In FIG. 5, how the light diffuses with and without the unevenness processing is indicated by arrows. The light emitted from the illuminant 4 travels in various directions when passing through the irregularities on the surface of the pedestal 2 and improves the light diffusion effect.

  Surface irregularity processing is generally referred to as texture processing or satin processing, and refers to a process that creates irregularities on the surface to make it matt. FIG. 6 illustrates a pedestal (a) that has actually been subjected to surface wrinkling and a pedestal (b) that has not been subjected to wrinkle processing. It is not limited to.

  It is preferable that the uneven processing has a roughness of about 20 μm to 200 μm.

  In the present invention, a satin-treated film can be attached to the surface of the top plate 2a of the pedestal 2.

  Furthermore, by making the bottom surface 27a reflect the light emitted from the light emitter 4, the amount of light when the present invention is used in the dark can be increased without changing the electric circuit, which is even better. Can ensure high visibility. In this case, since the electric circuit is not changed, the visibility can be improved without degrading the performance of the discharge time.

  In FIG. 7, the state in which the light emitted from the light emitter 4 is reflected by the bottom surface 27 a of the bottom cover 27 is indicated by arrows. The light irradiated in the direction of the pedestal bottom lid 27 is reflected without being absorbed by the bottom surface 27a of the bottom lid 27 being formed by a surface that reflects the light, so that the light can be used efficiently. it can.

  As means for reflecting light, the bottom cover 27 is formed using a glossy metal such as aluminum, and the natural gloss surface of the bottom cover 27 is exposed to the light emitter 4 side, or a waterproof sheet. 26, it is possible to provide a white sheet material that reflects light well, or to apply a white paint, or to provide a mirror on the bottom surface, but is not limited to these configurations, Any means may be adopted as long as the bottom surface 27a that efficiently reflects the light emitted from the light emitter 4 is formed.

  In addition, when the bottom lid 27 is formed using a glossy metal such as aluminum, it is possible to improve the visibility due to the light diffusion effect by making the bottom surface 27a uneven so that light is scattered. It is possible and preferable.

  Examples of the light diffusing material added to the resin forming the pedestal 2 include acrylic crosslinked fine particles, styrene crosslinked fine particles, silicone crosslinked fine particles, fluorine fine particles, glass fine particles, silica fine particles, calcium carbonate, barium sulfate, Examples include titanium oxide, alumina, talc, and mica. These may be used alone or in combination.

  The addition amount of the light diffusing material is preferably 0.001% by weight to 30% by weight, and more preferably 0.01% by weight to 10% by weight with respect to the entire resin as the base material of the base 2 such as polycarbonate. Preferably, 0.02% by weight to 1% by weight is most preferable.

  The particle size of the light diffusing material is preferably in the range of an average particle size of 0.01 μm to 100 μm, and more preferably 0.1 μm to 30 μm. Here, the average particle diameter means an average value when the entire particle diameter of the light diffusing material observed with an image of 3000 times is observed by an electron microscope. The particle diameter means a biaxial average diameter, that is, an average value of the minor axis and the major axis. Here, the minor axis and the major axis are the short side and the long side of the circumscribed rectangle that minimizes the area circumscribing each particle.

  Examples of the shape of the light diffusing material include a spherical shape, an elliptical shape, an indefinite shape, a needle shape, a plate shape, a hollow shape, a columnar shape, and a cone shape.

  Next, a specific configuration for detachably mounting the light emitter 4 on the light emitter mounting portion 24a will be described.

  FIG. 8 is an enlarged view of one light emitter mounting portion 24 a formed on the circular rib 24. As shown in the figure, the light emitter 4 is attached to a light emitter holder 6, and this light emitter holder 6 is detachably attached to the light emitter attachment portion 24a.

  The light emitter holder 6 is made of a plate-like member made of an appropriate synthetic resin, and a light emitter mounting hole 6a for attaching the light emitter 4 is formed therethrough. Here, a mode in which three light emitter mounting holes 6a are arranged in parallel in the vertical direction and one of the light emitters 4 is mounted is shown, but at least one light emitter mounting hole 6a may be provided. The light emitter holder 6 shown in the present embodiment can attach a maximum of three light emitters 4, and the number of light emitters 4 attached to one light emitter attachment portion 24a is appropriately increased or decreased according to the installation location or the like. Can be done.

  When the plurality of light emitter mounting holes 6a are formed in the light emitter holder 6, the present invention is not limited to a mode in which the light emitter mounting holes 6a are juxtaposed in the vertical direction as shown in the figure. A plurality may be arranged side by side in the direction.

  The light emitter mounting portion 24 a is notched in a concave shape from the bottom surface side of the pedestal portion 2 so as to match the outer shape of the light emitter holder 6. Concave ridges 24b and 24b made of slits are formed corresponding to the ridges 6b and 6b formed in the respective parts.

  For this reason, the light emitter holder 6 is removably engaged by attaching the protrusions 6b and 6b to the recesses 24b and 24b of the light emitter mounting part 24a from the bottom surface side of the pedestal part 2. Is done. Therefore, the mounting operation of the light emitter 4 on the light emitter mount 24a is extremely simple, and any one of the plurality of light emitter mounts 24a arranged in parallel in the circumferential direction of the base 2 is required to be visible. The light emitter 4 can be easily arranged by engaging the light emitter holder 6 with an arbitrary light emitting attachment portion 24a in order to perform light emission with emphasis in one direction or a plurality of directions.

  For example, FIG. 9A shows a case where the light emitter 4 is arranged in only one place and emits light mainly in one direction, and FIG. 9B shows that the light emitter 4 is arranged in two places and is mainly arranged in two directions. In the case of performing light emission, (c) shows a case where the light emitters 4 are arranged in three places to emit light mainly in three directions. In this way, the light emitter holder 6 having the light emitter 4 is selected by appropriately selecting the position of the light emitter attachment portion 24a so as to emit light with emphasis toward any one direction or a plurality of directions in the circumferential direction of the pedestal portion 2. It is possible to easily arrange the light emitters 4 by simply mounting the lens, and to easily realize a light emission mode that focuses on visibility in any one direction or a plurality of directions, not limited to all 360 ° directions. Can do.

  Moreover, according to this aspect, in order to perform light emission with an emphasis on any one direction or a plurality of directions, there is no need to make the specifications of the pedestal part 2 different for each installation place, and the pedestal part of the same specification No. 2 is used, and it is only necessary to appropriately select the number and position of the light emitter holder 6 to be attached to the light emitter attachment portion 24a, and can easily cope with any light emission in any direction. It is. In addition, as described above, since the pedestal portion 2 can diffuse light over a wide range by blending the light diffusing material, even if the number of the light emitters 4 is small, the adjacent light emission is also possible. Even between the bodies 4, the amount of light is not significantly reduced, and good visibility can be ensured over a wide range around the centered direction.

  FIG. 10 shows another embodiment of the light emitter holder 6. In this aspect, the electrical connection with the light emitter 4 is completed only by attaching the light emitter holder 6 to the light emitter mounting portion 24a.

  In other words, the light emitter mounting portion 24 a has first electrodes 24 c and 24 c on opposite side portions that are portions that contact the light emitter holder 6. Here, the concave portions 24b and 24b are formed by the first electrodes 24c and 24c. Further, the first electrodes 24c and 24c are directly connected by lead wires 24d and 24d when the power supply unit 5 is connected in parallel, or when connected in series by the lead wire 24d of the adjacent light emitter mounting portion 24a. It is indirectly electrically connected.

  On the other hand, the light emitter holder 6 has second electrodes 6c and 6c, respectively, on both side portions which are portions that come into contact with the light emitter attachment portion 24a. Here, the protruding portions 6b and 6b are formed by the second electrodes 6c and 6c. Further, the pair of terminals 4a and 4a of the light emitter 4 are electrically connected to the second electrodes 6c and 6c.

  According to the light emitter holder 6, the first electrode 24c of the light emitter mounting portion 24a can be obtained simply by engaging the protrusions 6b and 6b with the concave strip portions 24b and 24b of the light emitter mounting portion 24a and inserting them. 24c and the second electrodes 6c, 6c of the light emitter holder 6 are in contact with each other and electrically connected, and the light emitter 4 and the power supply unit 5 are electrically connected. Therefore, there is an effect that the mounting work of the light emitter 4 becomes easier.

  When a plurality of light emitters 4 are connected in series to the power supply unit 5 and there is a light emitter attachment portion 24a to which the light emitters 4 are not attached, the light emitters 4 are not provided as shown in FIG. An electrode in which the second electrodes 6c and 6c of the illuminant holder 6 are short-circuited with each other by a lead wire 6d is prepared, and the illuminant holder 6 is attached to the illuminant attachment portion 24a to which the illuminant 4 is not attached. The electrical connection between the first electrodes 24c and 24c may be ensured through the light emitter holder 6. In this case, the light emitter holder 6 may not have the light emitter mounting hole 6a. Although not shown, the light emitter holder 6 itself may be formed of a conductive material such as a copper plate or an aluminum plate.

  As mentioned above, although preferable embodiment of the self-light-emitting type | mold line-of-sight guidance sign column of this invention was described, next, an example of the self-light-emitting type base lamp of this invention is demonstrated.

  That is, in the self-luminous pedestal lamp in which the pedestal self-lumines, with respect to the pedestal part, the explanation of the pedestal explained in the above-mentioned self-luminous gaze guidance sign column is used as it is, and the explanation thereof is omitted. In addition, the operational effects are also incorporated and the description thereof is omitted.

  Examples of the present invention will be described below, but the present invention is not limited to such examples.

Example 1
2 is formed using translucent fluorescent red polycarbonate ("Caliber 303-10 GA116" manufactured by Sumitomo Dow), and the pedestal bottom 27a is aluminum glossy. A pedestal configured to be a surface was manufactured.
Of the total of 11 light emitter mounting portions 24a arranged side by side on the prepared pedestal portion, LEDs are installed on the light emitter mounting portion 24a immediately next to the power supply unit 5, and then every other LED has a total of 6 LEDs. Individually installed.

(Reference Example 1)
In Example 1, a pedestal was manufactured in the same manner as in Example 1 except that the bottom surface 27a was made of a black water sealing material, and six LEDs were installed in the same manner as in Example 1.

<Evaluation>
The LED was turned on in the dark and the difference in visibility was confirmed. The results are shown in FIG.
In addition, the pedestal was subjected to a visibility test on five subjects, and five out of five evaluated that the pedestal of Example 1 was “easy to see” more than the pedestal of Comparative Example 1.

  Furthermore, as shown in FIG. 13, the light quantity was measured in the LED lighting part (A part) and the brightest visible part (B part) other than the LED lighting part. The results are shown in Table 1.

  12, the pedestal configured so that the bottom surface 27a of the pedestal bottom cover 27 is an aluminum glossy surface reflects the light emitted from the light emitter at the bottom surface 27a, and more light is exposed to the outside. It was confirmed that it was released.

  Moreover, according to Table 1, while it is the same brightness in the LED lighting part, in the places other than the LED lighting part, it is about 3 times more when the bottom surface 27a is configured to reflect light. It was confirmed that the amount of light was reached.

(Example 2)
In the pedestal part 2 used in Example 1, the pedestal part bottom surface 27a is made of a black water sealing material, and a pedestal is manufactured in the same manner as in Example 1 except that the main body surface is roughened. Six were installed in the same manner as in Example 1.

<Evaluation>
As a reference example, the pedestal used in Reference Example 1 was used.
The LED was turned on in the dark and the difference in visibility was confirmed. The results are shown in FIG.
In addition, a visibility test was performed on five pedestals on the pedestal, and five out of five evaluated that the pedestal of Example 2 was “easy to see” more than the pedestal of Reference Example 1.

  By applying irregularities to the surface of the pedestal, the LED light travels in various directions when passing through the irregularities on the surface, so the light diffusibility is improved and the entire pedestal appears to emit light. It could be confirmed.
