DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road display device provided with a display board installed along a road to display road conditions and draw a driver's attention.

[0002]

2. Description of the Related Art Conventionally, as a display board of this kind, for example, for displaying a curve of a traveling road, only a generally used rectangular sign is drawn.

[0003]

The aforementioned shape markers are used on the assumption that they are generally known to indicate the curve of the road on which they are traveling. However, the driver cannot always immediately recognize that the display is a curve display of the traveling road just by looking at the shape sign, and even if the driver can immediately recognize the display of the curve of the traveling road, the driver cannot recognize the curve display. In some cases, the form (for example, a curve or a T-shaped intersection) that cannot be specifically recognized. Therefore, the effect of alerting the driver was insufficient.

An object of the present invention is to promote a driver's attention-raising effect on a display panel of a road display device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment First, a road display device according to a first embodiment of the present invention will be described with reference to FIGS.

The display panel 1 shown in FIG. 1 is a main component of a road display device installed along a road to display road conditions and draw a driver's attention. On the front side of the display board 1, a pair of left and right abstract display surfaces 2 in which the alert items are abstracted and displayed, and the same alert items between the two abstract display surfaces 2 are concretely displayed. Display surfaces 3 are provided side by side with each other. Incidentally, the alerting item on the concrete display surface 3 is a drawing of a curve of the traveling road as a pattern according to its form (for example, a curve that is gently curved or a T-shaped intersection). The attention item on the abstract display surface 2 is a drawing of a shape marker generally used to display a curve of a traveling road. A light-reflecting surface 4 is applied or adhered to the entire surface of the abstract display surface 2 except for the light-emitting portions 5 described later.

A plurality of light-emitting portions 5 (for example, LEDs) are provided on or near both the abstract display surfaces 2. The assumed outline which connects each of the light emitting units 5 sequentially along the outline of the abstract display surface 2 is shaped like a rectangle so as to display the same alerting information as the abstract display surface 2. . Note that all of the light-emitting portions 5 may be inside or outside the outline of the abstracted display surface 2, and some of the light-emitting portions 5 may have the same outline. May be outside.

Further, a plurality of light emitting units 6 (for example, LEDs) are arranged on or near the materialized display surface 3 (picture). The assumed outlines connecting the respective light-emitting portions 6 sequentially have the same shape as the light-emitting portions 5 group of the abstract display surface 2 so that the same attention items as those of the two abstract display surfaces 2 can be displayed. Shaped. The group of light-emitting units 6 on the materialized display surface 3 is provided between the groups of light-emitting units 5 on both the abstracted display surfaces 2 side by side. Note that all of the light emitting portions 6 may be inside or outside the outline of the embodied display surface 3 (picture). May be outside the same outline.

The solar cell 7, the storage battery 8, and the controller 9 (control means including the power supply control unit 10 and the display control unit 11) constituting the electric block circuit schematically shown in FIG. It is incorporated in the display panel 1 as a lighting control component.

In the daytime, the electricity generated by the solar cell 7 is supplied to the power control unit 10 via the storage battery 8 or directly. In the daytime, when the illuminance around the display panel 1 is large and the supply voltage in the power control unit 10 is higher than a preset value, the display control unit 11
Turns off the light emitting units 5 on the abstracted display surface 2 and the light emitting units 6 on the materialized display surface 3. At night, when the illuminance around the display panel 1 is low and the supply voltage in the power control unit 10 becomes lower than a preset value, the display control unit 11 emits light from the light emitting unit of the abstract display surface 2. The fifth group and the sixth group of light emitting units 6 on the concrete display surface 3 are turned on or off.

[Other Embodiments] * In the first embodiment shown in FIG. 1, both abstract display surfaces 2 are provided on the display panel 1, but in the second embodiment shown in FIG. Only the surface 2 is provided and arranged with respect to the embodied display surface 3 (picture).

* In the third embodiment shown in FIG. 4, the pattern of the materialized display surface 3 is changed to a T-shaped intersection in comparison with the first embodiment shown in FIG. The direction of the shape marker on the surface 2 is also changed. In addition, the light emitting unit 6 group is omitted from the picture on the materialized display surface 3.

* In another example of the third embodiment, which is also used in FIG. 4, the design of the materialized display surface 3 is changed to the light reflection surface 12 so that the form of the design can be recognized even at night. * Change the power supply to something other than the solar cell 7 or the storage battery 8.
