[Problems to be solved by the invention]
However, such a conventional self-luminous gaze guidance mark is installed in a place where the vehicle may approach mainly from the direction in which gaze guidance is performed, that is, the direction in which the light from the light emitter is difficult to reach, such as the end of the median strip. In such a case, the presence of the line-of-sight guide mark or its surrounding equipment cannot be fully recognized, and the line-of-sight guide mark or its surrounding equipment may be damaged due to a collision.
[0007]
At the intersection shown in FIG. 6, a median strip B is provided on the road R <b> 1, and a self-luminous gaze guidance mark 10 is installed on the median strip B. The self-luminous line-of-sight guidance marks 10A and 10B can clearly indicate the presence of the median strip B even at night by emitting light rays in the areas and directions A1 and A2, respectively. When the traveling vehicle C1 tries to turn to the lane on the side opposite to the median strip B, the gaze guidance mark 10A can be seen only from the direction A1 particularly at night. There is a risk of damaging the self-luminous line-of-sight guidance mark 10 and its surroundings by directly colliding with the light source or by rolling and rolling.
[0008]
Further, even when the vehicle C2 from the road R2 intersecting the road R1 makes a right turn or when the vehicle C3 from the road R3 makes a left turn, the direction from a direction other than the direction A1 in which the light from the self-luminous gaze guidance mark 10A is emitted Is difficult to recognize by the self-luminous line-of-sight guidance mark 10A, and the self-luminous line-of-sight guidance mark 10A and its peripheral equipment may be involved or damaged by collision.
[0009]
The present invention has been made in view of the above-mentioned problems, and is intended to provide a self-luminous gaze guidance mark that can be easily seen by road users at night even from directions other than the main target of gaze guidance. It is.

According to the present invention, the auxiliary light emitting unit is provided in a direction other than the main target on which the main light emitting unit guides the line of sight, thereby recognizing the line of sight guidance in the direction in which the light emitted from the main light emitting unit is difficult to reach even at night. It is possible to prevent entrainment and collision with the gaze guidance mark and its surrounding facilities. Further, since the auxiliary light emitting unit has a light emission luminance lower than that of the main light emitting unit, the auxiliary light emitting unit is not confused with the main light emitting unit, and the power consumption can be reduced.
[0012]
The auxiliary light emitting unit is preferably capable of emitting light in a direction that is difficult to cover with an integral light emitting unit, provided that its optical axis is at an angle of 90 to 150 degrees with respect to the optical axis of the main light emitting unit. .

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be specifically described below with reference to the drawings.
FIG. 1 shows an embodiment according to the present invention. A) is a perspective view from the front side, and B) is a perspective view from the back side. 2), the self-luminous line-of-sight guide 10 provided on the island D installed at the end of the median strip B has two main light-emitting sections that alternately flash on the front surface 31 of the box-shaped body 3 having a rectangular section. 1 is provided, and an awning 11 for maintaining visibility in the daytime is attached to the upper part of the main light emitting unit 1. The auxiliary light-emitting unit 2 is provided on the side surface 32 of the box-shaped body 3 so that the self-luminous gaze guidance mark 10 can be visually recognized with respect to the approach of the vehicle or the like from the rear portion H direction of the self-luminous gaze guidance mark 10. ing. The auxiliary light emitting unit 2 is not limited to the side surface 32 of the box-shaped body 3 and may be provided on the back surface 33 or the upper surface 34 according to the installation location or the required direction.
[0018]
FIG. 2 is a side view showing an example of the arrangement of the auxiliary light emitting units 2 in the self-luminous line-of-sight guide 10 shown in FIG. As shown in a) and f), they may be arranged evenly over the entire side surface, or they may be concentrated near the center of the side surface as shown in b) and d). The positions to be arranged may be biased as shown in FIG. Moreover, it may be arranged on the back surface 33 as shown in g) and h), and may be appropriately arranged according to the place where the self-luminous line-of-sight guidance mark 10 is installed and the direction in which the vehicle or the like is considered.
[0019]
The light emitting body used for the auxiliary light emitting unit 2 is not particularly limited, but the maintenance work can be reduced by using the LED, and the directivity of the light beam is increased so that the light beam is dazzled in a direction other than the direction where the light beam needs to be emitted. Is preferable. The auxiliary light-emitting unit 2 may be always lit, but the purpose of the auxiliary light-emitting unit 2 is to recognize the self-luminous gaze guidance mark 10 rather than the gaze guidance. Preferably, further blinking leads to reduction of power consumption. The blinking speed is preferably 0.5 to 10 times / second because visibility is improved.
[0020]
For example, when the emission color of the main light emitting unit 1 is yellow, if the emission color of the auxiliary light emitting unit 2 is set to a different color tone such as red, the possibility of confusion between the main light emitting unit 1 and the auxiliary light emitting unit 2 is reduced. The red color is also preferable because it will notify road users of danger.

[0022]
In FIG. 2B, the auxiliary light emitting unit 2 is provided on the side rear surface 35. Since the auxiliary light emitting unit 2 is provided at such a position, even if the directivity angle of the light beam of the light emitter used in the auxiliary light emitting unit 2 is not so large, the vehicle is approached from the side 32 direction and the rear 33 direction. On the other hand, a light beam can be emitted and the presence of the self-luminous line-of-sight guidance mark 10 can be recognized.
[0023]
The auxiliary light emitting unit 2 provided on the side back surface 35 may be arranged as shown in FIG. 4. The auxiliary light emitting unit 2 is equally provided on the side back surface 35 at 2 locations in b) and 5) in b). ing.
