The main body 11A has an upper flange portion 12 which is laterally extended in a circular shape on the outer periphery of the upper end portion, and the diameter of the outer periphery of the upper flange portion 12 is 150 mm which is a standard dimension such as the center line of road markings. The upper flange portion 12 is also formed so as to have the notches 13 and 13 which are notched linearly. Further, a step portion 14 for mounting the light transmission panel 20A is formed on the upper portion of the main body 11A, and a hollow portion for accommodating the light emitting body 27, the solar cell 28, the control circuit 30, and the like is formed below the step portion 14.

The lower container 16 is formed in a two-stage cylindrical shape consisting of a large diameter portion 16a on the upper side and a small diameter portion 16b on the lower side, and a lower flange portion 17 that laterally projects in a circular shape on the outer circumference of the lower end portion. The vertical fin portions 18 and 19 are formed on the side surface of the small diameter portion 16b so as to project laterally and extend in the vertical direction.

The large diameter portion 16a of the lower container 16 has a diameter that accommodates the main body 11A and is in close contact with the inner peripheral side of the upper flange portion 12 of the main body 11A, and the outer diameter of the lower flange portion 17 is the large diameter. The diameter is slightly smaller than the outer diameter of the portion 16a. Therefore, the outer diameter of the upper flange portion 12 is larger than that of the lower flange portion 17.

The light transmissive panel 20A is made of a disc-shaped transparent polycarbonate material, the upper surface 21 of which is formed as a sunlight incident surface and a light emitting surface of the light emitter 27, and is provided at a predetermined position on the outer peripheral edge at about 45. The cut surfaces 22, 22 that are inclined backward are formed.

Incident surfaces 23 A, 23 A in the form of inclined dents are formed on the lower surface of the light transmission panel 20 A, and two incident light surfaces are formed on each of the incident surfaces 23 A, 23 A via the light guides 26. A body 27 is attached. The light transmission panel 20A is fixed to the casing 10A with bolts 25 so that the upper surface thereof is lower than the upper surface of the upper flange portion 12 of the casing 10A by about 2 mm.

The light-emitting body 27 is composed of a high-intensity light-emitting diode, is configured to be supplied with electric power from the storage battery 29, and be controlled by the control circuit 30 to blink. As shown in FIGS. 2, 4, and 5, the two light emitters 27 are arranged so that their optical axes S1 radiate one side from the upper surface 21 via one incident surface 23A. Therefore, the other two light emitters 27 are arranged such that their optical axes S1 radiate to the other side from the upper surface 21 via the other incident surface 23A.

The control circuit 30 is composed of a lighting determination circuit, a blink control circuit, and the like. The lighting determination circuit detects the electromotive force of the solar voltage 28, and when the voltage falls below a certain level (at night when the amount of solar radiation decreases), activates the blinking circuit to supply the power of the storage battery 28 to the light emitter 27. However, the light emitting body 27 is configured to blink.

Next, the operation of the self-luminous line-of-sight guidance device configured as described above will be described.

In order to install the self-luminous gaze guidance device 1A on a road, first, a round hole for burial is excavated on the road. The burial round hole is set to have a diameter smaller than the diameter of the upper flange portion 12 of the main body 11A of the casing 10A and slightly larger than the large diameter portion 16a of the lower container 16, and is excavated by an excavating machine such as a core cutter.

When the self-luminous line-of-sight guide device 1A is inserted into this burial hole, the lower surface of the upper flange portion 12 contacts the road surface GL. Then, by backfilling the round holes, a filling material such as concrete is filled around the casing 10A and solidified. At this time, the directing direction of the optical axis S1 (directions of the cutouts 13 and 13 and the cut surfaces 22 and 22) is set to the arrival direction of the vehicle.

As a result, the self-luminous line-of-sight guidance device 1A is embedded in the road surface GL, and the upper flange portion 12 contacts the road surface GL to prevent the self-luminous line-of-sight guidance device 1A from sinking, and the lower flange The portion 18 prevents the escape. Further, the vertical fin portions 18 and 19 prevent rotation in the horizontal plane direction and hold the optical axis direction of the light of the light emitting body 27 at the time of installation.

Then, in the daytime when the amount of solar radiation of the sun is large, the sunlight is incident from the upper surface 21 of the light transmission panel 20, and the electromotive force of the solar cell 28 that receives the sunlight is stored in the storage battery 29. In the evening, when the amount of solar radiation decreases and the electromotive voltage of the solar cell 28 decreases and becomes lower than the reference voltage, the control circuit 30 supplies the electric power of the storage battery 29 to the light emitting body 27 to control the light emitting body 27 to blink. . At this time, the light of each light-emitting body 27 travels along the optical axis S1 from the incident surface 23A in the light transmission panel 20A, and is emitted into the atmosphere from the upper surface 21. In addition, a part of the scattered light of the light-emitting body 27 in the light transmission panel 20A is emitted through the cut surface 22 to improve the visibility of the self-luminous line-of-sight guidance device 1A.

When the wheels of the traveling vehicle pass over the self-luminous gaze guidance device 1 A, the wheels first come into contact with the cutout portion 13 and the cut surface 22 of the upper flange portion 12, and then the upper flange portion. 12 and the upper surface of the light transmission panel 20A.

At this time, the wheel mainly contacts the upper surface of the upper flange portion 12, and the wheel engages with the step between the upper flange portion 12 and the light transmission panel 20A to prevent the wheel from slipping. In addition, the notch 13 which is a part of the upper flange 12 and the cut surface 22 which is disposed opposite to the notch 13 reduce the impact when the wheel passes and reduce the traveling obstacle. Further, the upper flange portion 12 does not protrude beyond the line width of the center line of the road marking, and avoids hindering the vehicle traveling.

FIGS. 6 and 7 show a self-luminous line-of-sight guidance device 1 B that emits light from a cut surface. In the following description, the same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

The self-luminous line-of-sight guidance device 1 B is configured to include a light transmission panel 20 B having light emitter holes 24, 24 for mounting two light emitters 27, 27. In the light transmission panel 20B, the upper surface 21 is formed as a sunlight incident surface, and the cut surfaces 22 and 22 are formed as emission surfaces of the light emitter 27, respectively.

As shown in FIG. 7, the luminous body 27 is attached to the luminous body hole 24 so that its axis line is orthogonal to the incident surface 23B. Then, the optical axis S2 of the light emitter 27 is configured to radiate into the atmosphere through the cut surface 22.

According to this self-luminous line-of-sight guidance device 1B, the light emitting body 27 emits light from the emission surface (cut surface 22) at the lower position, and the optical axis S2 reaches the farther vehicle driver.

Let it happen.
