When there is no vehicle detection signal, the control circuit 40 causes the red blinking portions 45 and 45 to blink, and the white blinking portions 46 and 46 to turn off. Then, the red light emitters 35 in both A and B directions,
35 flashes at predetermined intervals, and the white light emitters 36, 36 in both the A and B directions are in a light-off state (state I in Table 1).

At this time, the red light emitter 35 in both the A and B directions
Is reflected by the reflecting mirror 20 directly above along the optical axis S indicated by a dashed line in FIG.
The light enters the reflecting mirror 17 more. And the light is the reflecting mirror 1
7 into the light transmissive panel 10 from the outer peripheral surface, and the radiation surface 11
Radiates from the air into the atmosphere. The radiation light from the radiation surface 11 is emitted at a slightly upward angle with respect to the road GL.

When the light of the red light emitter 35 is projected on the horizontal plane, the light axis S is set to the radiation surface 13 when the reflecting mirror 20 and the radiation surface 11 are parallel in a horizontal view (the state of FIG. 1).
At right angles to the atmosphere in the A direction or the B direction. At this time, the red light emitting body 35 emits light in a plane spread, for example, at a width of 15 degrees to the left and right around the optical axis S, and refracted by the radiation surface 11 so that the light spreads right and left around the optical axis S.
It is emitted to the atmosphere in a 49-degree range, which is 4.5 degrees. In the white light emitting body 36, the reflection and refraction of the radiated light, and the emission and spread of the horizontal plane are the same as those described above.

Here, the adjustment of the direction of the optical axis S of the red light emitting body 35 on the horizontal plane by the reflecting mirror rotating mechanism 15 will be described.

First, the driving body 25 through the driving bolt 29
Is turned in the opposite direction to the required direction, the left and right reflecting mirrors 1
The mirrors 7 and 17 rotate in a required direction in conjunction with each other, and the reflecting mirrors 20 and 2 rotate.
The optical axes S, S orthogonal to 0 are displaced in the required direction.

For example, as shown in FIG. 7, the displacement angle (swing angle) of the horizontal radiation angle is such that the optical axis S of the light reflected by the reflecting mirror 20 on the A direction side is shifted with respect to the reference direction axis S ₀ . shake to 6.3 degrees to the left, the optical axis S is 10 degrees to the left (with respect to the reference axis S ₀₎ shaken with emitted into the atmosphere from the radiating surface 11.
Note that the optical axes S, S of the left and right red light emitters 35, 35 extend in parallel, and the optical axis direction of the white light emitters 36, 36 is also
It is parallel to the red light emitter 35 and varies together by the same angle.

FIG. 8 shows that the optical axis S is shifted 10 degrees to the left from the radiation surface 11.
Shows the spread on the horizontal plane of the luminous body light in a state where the luminous body lights are installed at intervals of 20 m, and the extension of the optical axis S is about 60 m in the direction A on the left curve road R having a radius of 200 m.
Cross the vehicle lane at the end. Therefore, the driver of the vehicle M arriving at a point 60 m away can directly visually recognize the light source of the high-luminance red light emitter 35 on the optical axis S. Also,
Continuity of a large number of variable directional self-luminous studs 1 and red luminous body 3
The flat spread of the five lights at an angle of 49 degrees also acts, so that the alignment of the curved road R can be clearly recognized.

The opposite lane of this road R (direction B)
Is a right curve with a radius of 200 m. Reflection mirror 2 on B direction side
When the optical axis S of the reflected light at 0 is swung 5.2 degrees to the left, the optical axis S of the B direction side red light emitter 35 is 7 degrees to the left from the radiation surface 11 (relative to the reference direction axis S ₀ ). Shake and radiated into the atmosphere. Then, the optical axis S crosses the vehicle traveling lane on the opposite lane side at about 60 m in the B direction (see FIG. 9). When the adjustment in the optical axis direction is completed, the mounting bolts 23, 23 and the drive bolt 29 are sealed and fixed on the upper surface of the light transmitting panel 10 with a sealing material.

For example, when the vehicle M whose headlights are turned on from the direction A approaches the variable directional self-luminous stud 1, the headlight rays are reversed from the radiation surface 11 along the optical axis S. The vehicle sensor 37 on the A direction side receives the light reflected by the reflecting mirror 20.

On the basis of the vehicle detection signal from the vehicle sensor 37, the control circuit 40 blinks the red light emitter 35 on the A direction side, and keeps the white light emitter 36 off, leaving the red light emitter 35 on the B direction side. Is turned off, and the white light emitter 36 is controlled to blink (operation II in Table 1). The light of the white light-emitting body 36 in the B direction is emitted from the radiation surface 11 into the atmosphere in the B direction in parallel with the optical axis S shown in FIGS.

That is, the approach direction side of the vehicle M is kept blinking normally, the emission color is changed to the opposite direction, and the driver of the vehicle M traveling in the opposite lane is alerted of the curved road R. In addition, it acts to notify the presence of an oncoming vehicle.

When the vehicle M whose headlights are turned on from the B direction side approaches the variable directional self-luminous stud 1, the headlight rays are transmitted from the B direction side radiation surface 11 to the optical axis S.
, And is reflected by the reflecting mirror 20 and received by the vehicle sensor 37 on the B direction side.

On the basis of the vehicle detection signal from the vehicle sensor 37, the control circuit 40 blinks the red light emitter 35 in the B direction and turns off the white light emitter 36 while keeping the white light emitter 36 in the off state. Is turned off, and the white light emitter 36 is controlled to blink (operation III in Table 1). Then, the light of the white light emitting body 36 on the A direction side is emitted from the radiation surface 11 into the atmosphere in the A direction in parallel with the optical axis S.

Further, when the vehicles M, M whose headlights are turned on in both directions A, B approach the variable directional self-luminous stud 1, the vehicle sensors 37, 37 in both directions receive the headlight rays. Thereby, the control circuit 40
The red light emitters 35 on both sides are turned off, and the white light emitters 36 are controlled to blink (operation IV in Table 1). The light of the white light emitters 36 and 36 is
It is radiated from 1 and 11 into the atmosphere in both A and B directions.
