BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a preferred embodiment of the present invention.

First, the structure of the traffic sign 1 according to the present embodiment will be described with reference to FIGS.

FIG. 1 shows the overall appearance of the traffic sign 1. The traffic sign 1 is a post 21 formed by an elongated round pipe.
Is provided. At the time of installation, the lower end of the post 21 is buried in the ground E and stands up. On the other hand, the solar cell unit 22 is mounted on the upper end of the post 21. Solar cell unit 2
Numeral 2 has a solar cell 7 on its upper surface, and has a built-in battery 8 for charging the output power of the solar cell 7 (see FIG. 6). The solar cell 7 and the battery 8 constitute a power supply unit 9.

On the other hand, a marker unit 23 is mounted above the post 21. That is, the back surface of the marker unit 23 is attached and fixed to the post 21 using a pair of upper and lower mounting brackets (mounting bands) 24 and 25. As shown in FIG. 2, the sign unit 23 is formed in a case shape having a hollow inside. The surface is the display surface 2 and is formed in a diamond shape. On the display surface 2, a graphic A relating to a traffic sign is displayed. In this embodiment, the entire display surface 2 is yellow, and a cross figure A representing a crossroad intersection is drawn in black at the center. Such traffic signs are prescribed by laws and regulations.

On the other hand, the display surface 2 is provided with a first light emitting section 3 along the outline of the figure A. As shown in FIGS. 3 and 4, the first light emitting unit 3 includes a plurality of light emitting diodes 3a, 3b, 3.
are arranged at predetermined intervals along the outline of the figure A. Red is desirable as the color of the light emitting diodes 3a. Further, the display surface 2 is provided with a second light emitting unit 4 in which a character B corresponding to the figure A is imaged. In this case, since the graphic A represents the intersection, the corresponding character is the character B of "Tomare" indicating a temporary stop. Second light emitting unit 4
Represents a plurality of light emitting diodes 4 as shown in FIGS.
The character B is formed by a, 4b, 4c, 4d, 4e,. The color of the light emitting diodes 4a is preferably red.

Further, inside the marker unit 23, there is provided a control main unit 6 for controlling the first light emitting unit 3 and the second light emitting unit 4 to emit light alternately. As shown in FIG. 6, the control main unit 6 includes the battery 8 and the light sensor 1 for detecting light and darkness.
0 are connected respectively. The control main unit 6 and the power supply unit 9 constitute the operation control unit 5.

Next, the operation of the traffic sign 1 according to the present embodiment will be described with reference to FIGS.

First, in the daytime, since the optical sensor 10 detects the brightness, the control main unit 6 is in an operation stop state. Therefore, neither the first light emitting unit 3 nor the second light emitting unit 4 emits light. Therefore, during the daytime, the traffic sign (figure A) displayed on the display surface 2 can be visually recognized as shown in FIG. In the daytime, the output power of the solar cell 7 is charged to the battery 8.

On the other hand, when the light becomes dark and the optical sensor 10 detects a certain darkness, the control main unit 6 executes a control for causing the first light emitting unit 3 and the second light emitting unit 4 to emit light alternately. That is, FIG.
As shown in (1), when the optical sensor 10 detects a certain darkness at the point of time Pd, the first light emitting unit 3 and the second light emitting unit 4 alternately turn on and off. In this case, the time for turning on and off the light can be set to about several seconds, and the time can be arbitrarily set by the adjustment function of the control main unit 6.

FIG. 4 shows a state in which the first light emitting section 3 is turned on. Since the first light emitting unit 3 represents the outline of the figure A related to the traffic sign, the figure A at the crossroad intersection appears black at night. On the other hand, FIG. 5 shows a state where the second light emitting unit 4 is turned on.
The second light emitting unit 4 displays the letter B of “Tomare” corresponding to the graphic A in red. In addition, when it becomes bright at dawn and at the point of time Pr in FIG. 7, since the optical sensor 10 detects the brightness, the control main unit 6 is in an operation stop state. Therefore, the light emission of both the first light emitting unit 3 and the second light emitting unit 4 is stopped.

Therefore, according to such a traffic sign device 1, the light emission of the first light emitting portion 3 and the second light emitting portion 4 allows the display surface 2 to be exposed to the headlight light from a distant place during driving at night. However, the display on the display surface 2 can be recognized, and the smoothness and safety of traveling can be significantly improved. In addition, the first light-emitting unit 3 and the second light-emitting unit 4 emit light alternately, and the first light-emitting unit 3 represents the outline of the figure A related to the traffic sign, while the second light-emitting unit 4 corresponds to the figure A. Since the character B is represented, the alertness at night is dramatically improved.

FIGS. 8 to 10 show modified examples of the traffic sign displayed on the display surface 2. FIG. FIG. 8 shows an example in which a horizontal T-shaped graphic A representing a three-way intersection and a character B of “slow” corresponding to the graphic A are displayed, and FIG. 9 shows a graphic A of a curved arrow representing a curve and the graphic A. FIG. 10 shows an example in which the corresponding letter B of “Caution” is displayed. FIG. 10 shows a rectangular sign unit 23 attached to the two posts 21a and 21b, a straight arrow A representing the traveling direction, and a corresponding figure A. The example which displayed the letter B of "speed stop" is shown, respectively. These modifications can be implemented in the same manner as in the basic embodiment shown in FIGS. The traffic sign to be displayed is not limited to the example, and various other traffic signs are applied.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment,
The configuration, shape, display contents, and the like of the details can be arbitrarily changed without departing from the spirit of the present invention.

As described above, the traffic sign device according to the present invention has a first light emitting portion constituted by a plurality of light emitting diodes arranged at predetermined intervals along the outline of a figure, and a traffic light at a predetermined interval. A second light emitting unit configured to imitate a character corresponding to a figure by a plurality of arranged light emitting diodes is attached, and a control main body unit for performing control, a solar cell and a battery for charging output power of the solar cell are provided. Since the power supply unit includes the operation control unit that causes the first light emitting unit and the second light emitting unit to emit light alternately, the following remarkable effects are obtained.

By the light emission of the first light emitting unit and the second light emitting unit, the display on the display surface can be recognized even from a distant place where the headlight light does not hit the display surface during driving of the vehicle at night, and the smooth running can be achieved. And the safety can be significantly improved.

The first light emitting unit and the second light emitting unit emit light alternately, and the first light emitting unit represents a contour of a figure related to a traffic sign, and the second light emitting unit represents a character corresponding to the figure. The ability to call attention can be dramatically increased.
