Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-luminous gaze guide light installed on a road shoulder or the like.

[0002]

2. Description of the Related Art For the purpose of preventing head-on collisions or out-of-road departure accidents in places with poor visibility, sharp curves, etc., on a road where vehicles travel, a line-of-sight guidance light (derineta) is installed on the shoulder of the road. A system has been adopted to notify the driver of the approach of oncoming vehicles and the shape of the curve (road alignment) to avoid danger.

[0003] This type of line-of-sight guide light includes a reflection type and a self-luminous type. In many cases, the reflection type line-of-sight light is individually installed in an up lane and a down lane.

On the other hand, the self-luminous line-of-sight guide light may be provided with a pair of two luminous bodies provided bidirectionally in an up lane and a down lane on one side of a lane shoulder due to a problem of securing power supply. Many. In addition, LEDs are used as a light source (luminous body) of recent self-luminous gaze guidance lights. However, since the light emission of the LEDs has a narrow viewing angle, when the LED is installed in a curved section, it is necessary to follow the road alignment. In addition, it is necessary to adjust the directions of the individual LED light emitters so that they can be seen by the driver. For such a reason, a method is adopted in which two individual LED light emitters are installed as a pair. As one example, as shown in FIG. 10, one line-of-sight guide light 200 is formed by pairing two individual LED light emitters 201 and 202 for the up lane and for the down lane.
00 is installed on one side of the road such as a curve section.

[0005]

SUMMARY OF THE INVENTION As described above, an LED
When a self-luminous line-of-sight guide light using the LED is installed, a large space is required because a large number of LED light emitters are installed on one side of a road on the opposite lane. Further, when a large number of rectangular LED luminous bodies as shown in FIG. 10 are arranged along the road, the whole looks complicated, which is not preferable in terms of external design.

The present invention has been made in view of such circumstances, and has a structure including two LED light emitters for an up lane and a down lane, which requires a small space for installation and an external design. The purpose of the present invention is to provide a line-of-sight guide light that is excellent in performance.

It is characterized by having an adjustment mechanism for individual adjustment, wherein the two LED emitters are housed in one cylindrical case.

[0008] According to the gaze guide lamp of the present invention, two LEs
Since the D light emitters are not installed individually, but are arranged in one cylindrical case, the installation space can be reduced as compared with the conventional visual guide light shown in FIG. The design also improves.

In the line-of-sight guide light of the present invention, the two LED luminous bodies arranged in one cylindrical case are structured to be rotatable about the same rotation axis, and each LED luminous body is set by setting the rotation angle. By adopting a configuration that adjusts the direction of the shaft, the installation space for the rotating shaft can be reduced, the space saving in the cylindrical case can be efficiently achieved, and the space in the cylindrical case is effectively used. be able to.

Further, in the line-of-sight guide light of the present invention, two adjusting holes are provided in the adjusting mechanism and extend in an arc shape around the rotation axis.
