The capacitor 70 may be adapted to emit light.

The prism member 40 is fitted to the prism member fitting portion 28 of the road tack body 20 as described above. The prism member 40 is made of transparent synthetic resin, and the speed of light inside the prism member 40 is slower than the speed of light inside air.

Unlike that, replacement of the component (capacitor 70) is almost unnecessary, and once installed, it can be used semipermanently as it is.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIGS. 7 and 11, focusing on the differences from the first embodiment. As shown in FIG. 7, the ground portion 92 of the light emitting type road tack 90 has a substantially parallelogram shape in a plan view. Light is emitted from the prism member 94 (light emitting diode in the prism member 94) to the outside.

Therefore, this light emitting type road tack 90 is shown in FIG.
As shown in 1, partition line D that separates the roadway and sidewalk of road R
It can be suitably provided on the above. At this time, since the height of the ground portion of the light emitting type road tack 90 is low, it is convenient for shoveling. Moreover, since light is emitted upward as in the first embodiment, it is possible to call attention to pedestrians and bicycles.

Also, as shown in FIG. 11, when the parking lot P or the like is provided on the side of the road R, the light emitting type road tack 90 can also be suitably provided at the boundary portion thereof. . That is, the boundary line portion is indicated by emitting the light L, but when traveling toward the parking lot P, it is necessary to get over the light emitting type road tack 90. At this time, since the height of the ground portion of the light emitting type road tack 90 is low, it does not hinder the running of the automobile.

This light emitting type road tack 90 can also be used semipermanently once installed.

<Third Embodiment> Next, a third embodiment of the present invention will be described with reference to FIGS. 8 to 11, focusing on the differences from the first embodiment.

As shown in FIGS. 8 to 10, two prism members 140a and 140b are attached to the front and rear sides of the light emitting type road tack 100 (road tack body 120).
Four light emitting diodes 150 are attached to each of the prism members 140a and 140b. In addition, the prism members 140a, 1

The electricity generated by the solar cells 130a and 130b is stored in the capacitors 170a and 170b, and the electricity is generated in the capacitors 170a and 170b.
Each prism member 140a, 1
Each light emitting diode 150 of 40b emits light. The electricity generated by one solar cell 130a is stored by the four capacitors 170a under the action of the electronic circuit of the electronic circuit board 160a, and the electricity stored in each of the capacitors 170a causes each of the prism members 140a to operate. The light emitting diode 150 is adapted to emit light. The same applies to the other solar cell 130b, electronic circuit board 160b, capacitor 170b, and prism member 140b.

This light emitting type road tack 100 can be suitably installed on the center line CL of the road R, as shown in FIG. Then, the light L can be emitted to the opposite lanes, but even at that time, since the height of the ground portion 112 of the light emitting type road tack 100 is low,
It is possible to reduce the impact given to the automobile when crossing the center line CL such as when making a U-turn. The light emitting type road tack 100 can also be used semipermanently once installed. The light emitting type road tack 100 is similar to the second embodiment in that the ground portion 11
2 may have a substantially parallelogram shape in a plan view.

<Fourth Embodiment> Next, a fourth embodiment of the present invention will be described with reference to FIGS. 12 to 14 focusing on the differences from the first embodiment and the like.
It will be described based on. As shown in FIGS. 12 and 13,
The ground portion 212 of the light emitting type road tack 200 has a rounded and substantially square shape in a plan view. And
On the upper portion of the road tack main body 120, one prism member is provided for each of the four side portions (prism members 240a, 240b, 240c, 240d). Four light-emitting diodes 250r that emit red light are assembled to the pair of contradictory prism members 240a and 240c, and the other pair of contradictory prism members 240b and 24c.
In 0d, there are four light emitting diodes 250y that emit yellow light.
They are assembled one by one.

In addition, on the upper portion of the road tack main body 220,
Four solar cells 230a to 230d are provided corresponding to each prism member 240a to 240d. In addition, in the storage portion 224 of the road tack main body 220, each prism member 2 is
40a-240d light emitting diodes 250r, 250
Corresponding to y, electronic circuit boards 260a to 260d and capacitors 170a to 170d are housed.

The electricity generated by the solar cells 230a to 230d is stored in the capacitors 270a to 270b, and the capacitors 270a to 170d are stored.
Each prism member 240a-2
The light emitting diodes 250r and 250y of 40d emit light. Note that the electricity generated by one solar cell 230a is stored by the four capacitors 270a under the action of the electronic circuit board 260a, and the electricity stored in each of the capacitors 270a causes each light emitting diode 250r of one prism member 240a. Is designed to emit light. The other solar cell 230b-2
30d, electronic circuit boards 260b to 260d, capacitors 270b to 270d, prism members 240b to 240d.
But the same is true.

This light emitting type road tack 200 can be suitably installed at the central portion of an intersection (four-way intersection) as shown in FIG. Then, red light Lr is emitted from the prism members 240a and 240c (light emitting diode 250r) in one contradictory direction, and prism members 240b and 240d (light emitting diode 250) in another contradictory one direction.
The yellow light Ly is emitted from y).

Due to the above constitution, this light emitting type road tack 20
At 0, it is possible to call attention to the car (the driver) instead of the traffic light at an intersection where the traffic volume is not so heavy. Also, this light emitting type road tack 200 is not obstructive to the traveling of the automobile because the height of the ground portion 212 is low, and can be used semipermanently.

<Fifth Embodiment> Next, an embodiment corresponding to the invention of claim 2 will be described with reference to FIG. 15 focusing on the difference from the first embodiment and the like. This light emitting type road tack 300 is
A light emitting diode 350 is provided inside the underground portion 304 so as to face upward, and a mirror-like reflecting surface 340 is provided on the front side thereof.
Are formed. A light transmission part 342 made of transparent resin is provided on the reflection direction side of the reflection surface 340. Therefore, the light L emitted from the light emitting diode 350 is reflected by the reflecting surface 340, and the light transmitting portion 342.
And is emitted almost horizontally with respect to the road surface RS.

Even with such a structure, the light emitting diode 84 can be provided in a portion below the position corresponding to the direction of light emission to the outside, and the height of the ground portion 302 can be reduced.

The light emitting type road tack 300 can also be used semipermanently once it is installed because the electricity generated by the solar cell is stored by the capacitor.

In the first to fourth embodiments, the light emitting diode emits light into the prism member (more precisely, the light emitted from the light emitting diode into the air in the light emitting diode mounting hole is refracted). Incident on the prism member) and is refracted at the refracting surface between the prism member and the air. However, the present invention is not limited to this, and the light emitting diode may first emit light into the air, and a prism having a triangular prism shape may be provided in front of the light emitting diode to refract the light. In that case, light is refracted twice when it enters the prism from the air and when it exits the air from the prism.

The first to fourth embodiments are for refracting light on the refracting surface, and the fifth embodiment is for refracting light on the reflecting surface. The light may be emitted to the outside after being refracted by and reflected by the reflection surface.

In the above embodiment, the electricity generated by the solar cell is stored by the capacitor, and the light emitting diode emits light based on the electricity. However, the electricity generated by the solar cell is stored by the capacitor and the storage battery. Alternatively, the light emitting diode may be caused to emit light by the electricity stored by both of them. In that case, it is particularly effective when the time (dark time) for which the light is emitted is too long to sustain the light emission only with the electricity stored by the capacitor.

[0042]

As described above, according to the present invention,
Since the height of the ground portion can be reduced without reducing the light emission amount, it does not hinder the traveling of the automobile or the like, and the automobile can smoothly travel. Also,
It is not an obstacle when a single vehicle gets over, and it is safe without the risk of falling. In addition, it does not interfere with work such as snow shoveling. Further, since the capacitor stores the electricity generated by the solar cell, unlike the case of using the storage battery, replacement of parts (capacitor) is almost unnecessary, and once installed, it can be used semipermanently as it is. Therefore, maintenance after installation on the road becomes easy (almost unnecessary), and the cost can be significantly reduced by that amount.
