[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of an obstacle indicator light provided at, for example, a road branch on a highway or a tip of a median strip.

[0002]

[Prior art]

 Obstacle indicators may be provided to indicate to the driver the presence of road structures, such as road junctions, median strips and bridge piers, which are obstacles to traffic on highways. This obstacle indicator light is generally used to alert the driver with a yellow flashing light to prevent collision or contact with an obstacle. There are some lamp units equipped with obstacle indicator lights (one-lamp type), two (two-lamp type), or four lamp units. This obstacle indicator light is usually installed on a structure that becomes an obstacle, for example, a concrete body that constitutes the tip of a road branch, and thus the position of the obstacle indicator light is set in this way. It is raised so that the driver can see it from a distance.

[0003]

[Problems to be solved by the device]

 However, when an obstacle indicator light is provided on the obstacle structure, the tip of the obstacle may travel before the obstacle indicator light. For this reason, even though the driver was aware of the obstacle indicator light and was aware of it, there was a risk of collision or contact with the protruding portion at the tip of the obstacle. In order to eliminate such a fear, a road light should be installed near the obstacle so that the driver can recognize the shape of the obstacle and that there is a protruding portion. However, the provision of road lights was not only expensive, but many structures that were obstacles were located in the center of the road, and lighting by road lights was not always effective. .

The present invention was made in view of the above problems, is inexpensive, and effectively illuminates an obstacle and its surroundings to prevent a vehicle collision or a contact accident with the obstacle. It is an object of the present invention to provide an obstacle indicator light that can be further prevented.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the obstacle indicator light according to the present invention is an obstacle indicator light for indicating to a driver the existence of a structure which becomes an obstacle on a road, and illuminates the structure and its surroundings. The gist is to configure a lighting device.

[0006]

[Action]

 The obstacle indicator light indicates to the driver that there is an obstacle structure on the road and illuminates this structure to clarify the shape, for example, to let the driver recognize the protruding portion of the obstacle. Prevent car collisions and contact accidents.

【Example】

 A first embodiment of the obstacle indicator lamp according to the present invention will be described below with reference to FIGS. In this embodiment, the road obstacle 1 is the structure that becomes an obstacle on the road. A railing section 2 is provided on the road branching section 1 along the lane direction, and an obstacle indicator lamp 3 is provided at a tip portion of the railing section 2.

As shown in FIG. 2, the obstacle display lamp 3 is provided with two pairs of lamp units 4 and 4. Even if the pair of lamp units 4 is disconnected, another pair of lamp units is connected. The function can be maintained by G4. In such a configuration, the blinking method of the lamp unit 4 is a method in which the upper pair and the lower pair alternately blink, or one lamp in the upper position and one in the lower lamp for each upper or lower pair. There is a method in which one lamp in the layout blinks in conjunction with each other, and it is possible to change the wiring by recombining internal wiring or inserting a blinker. An illumination device 5 according to the present invention is constructed above these obstacle indicator lights 3. FIG. 3 is a plan sectional view of the illumination device 5, FIG. 4 is a longitudinal sectional view, and FIG. 5 shows an example of a reflecting mirror formed inside.

A light source 6 is provided above the interior of the lighting device 5. An umbrella portion 8 forming a part of the reflecting mirror 7 is formed so as to cover the light source 6 from above, and the emitted light of the light source 6 is reflected by the umbrella portion 8 toward the foot of the obstacle indicator lamp 3. It is possible to illuminate the vicinity 1a of the tip of the road branch 1 which is a structure.

On the lower back side of the light source 6, there is formed a front reflecting portion 9 which constitutes a part of the reflecting mirror 7. The front reflecting portion 9 forms a part of a substantially conical shape, and efficiently emits the reflected light forward.

On the outside of the reflecting mirror 7, a front lens 10 having a substantially rectangular tube shape is provided. On the outer surface or inner surface of the front lens 10, a diffusing lens step 11 for refracting the light reflected by the front reflecting portion 9 downward and forming a predetermined illumination range is formed.

FIG. 6 shows a second embodiment of the obstacle indicator lamp according to the present invention, and only parts different from the first embodiment will be described. In the present embodiment, the light source 6 is arranged below the inside of the illuminating device 5, and the radiated light reflected upward by the reflecting mirror 12 having a bowl-shaped parabolic reflecting surface is further arranged above the inside of the illuminating device 5. The reflector plate 13 having a conical cross-section irradiates the obstacle indicator lamp 3 in the direction of the foot of the obstacle indicator lamp 3 to illuminate the vicinity 1a of the tip of the road branch 1. It goes without saying that the surface of the reflection plate 13 can be designed in a concave shape, a convex shape, or the like, appropriately considering the reflection efficiency.

The operation of the lighting device 5 according to the present invention will be described below with reference to FIGS. 7 and 8. That is, in the case of the first embodiment described above, the light that goes upward from the light source 6 is reflected by the umbrella portion 8 of the reflecting mirror 7 and emitted downward, and according to the circular shape of this umbrella portion 8, it is shown in FIG. Such an area 14 is illuminated. At this time, the light directed downward and forward from the light source 6 directly illuminates the illumination range 14. Further, it is possible to intensively illuminate a necessary portion below, that is, the vicinity of the road branch 1 which is a structure, by the diffusion lens step 11. The light traveling downward and rearward from the light source 6 is reflected by the front reflecting portion 9 and is condensed forward. As a result, as shown in FIG. 7 and FIG. 8, the light is not wasted in the portion where the rear illumination is unnecessary, and the front can be illuminated brighter. Can be illuminated. Therefore, it is possible to illuminate the shape of the vicinity 1a of the tip of the road bifurcation 1, which is a structure that becomes an obstacle, and make this shape visible to the driver even from a position far away. As a result, the driver can recognize that there is an obstacle by the indicator light and at the same time recognize the shape of the road branch portion 1 which is an obstacle, and the driver is traveling ahead of the obstacle indicator light 3 near the tip 1a. The concrete part of can be seen from a sufficiently distant position. Therefore, it is possible to prevent the vehicle from accidentally colliding with or contacting the projecting portion of the road branch portion 1 as in the conventional case.

In addition, in the case of the second embodiment, the downward light from the light source 6 is emitted upward by the reflecting mirror 12 having a parabolic reflection surface, and is reflected on the upper part of the illuminating device 5. The illumination area 14 as shown in FIGS. 7 and 8 can be directly illuminated by the plate 13.

Further, since the light from the lighting device 5 illuminates only the foot of the obstacle indicator lamp 3 and does not directly enter the eyes of the driver, it may dazzle the driver and impair the driving operation. Absent. In addition, because of the shape of the reflecting mirror 7 and the function of the front lens 10 as a lens, only the necessary range 14 shown in FIGS. 7 and 8 is illuminated, so that the emitted light from the light source 6 is not lost.

Further, since the obstacle indicator lamp 3 itself is provided with the illumination device 5, the illumination efficiency is high and the illumination device 5 is higher than the case where the vicinity of the obstacle indicator lamp 3 is illuminated by, for example, a road light. The cost for installing the can also be kept low. Moreover, since the light emitted from the illumination device 5 does not illuminate the lamp unit 4 of the obstacle indicator lamp 3 (see FIGS. 2 and 4), the blinking light of the obstacle indicator lamp 3 such as yellow is emitted from the driver. It's not hard to see.

In the above embodiments, the obstacle structure has been described as the road branch 1. However, in other embodiments, other structures such as median strips and piers may be used. Good. Further, in the present embodiment, there are four lamp units 4 of the obstacle indicator lamp 3, but in other embodiments, it may be two or one. The emitted light of each lamp unit 4 does not necessarily have to be yellow, and can be appropriately modified.

[0018]

[Effect of device]

 Since the obstacle indicator light according to the present invention is configured as described above, the obstacle indicator light itself has a lighting device that illuminates the structure that becomes the obstacle, thereby making it an obstacle to the driver. By not only indicating the existence of an object, but also clarifying the shape of the obstacle, for example, making the protruding portion recognized, the occurrence of a car collision or contact with the obstacle can be prevented in advance. The effects obtained by implementing the present invention are extremely large.
