For reference, in the drawing, one signal display device 100 for a crosswalk is shown for convenience, but there may be two or more, so it should be said that all of these matters fall within the scope of the present invention.

The device body 110 is an external structure of the crosswalk signal display device 100 according to this embodiment and is installed on a road, for example, a sidewalk, around a crosswalk. In this embodiment, the device body 110 is applied as a type installed on the road, for example, like a street light. That is, the device body 110 may include a base 120 and a column 130.

The base 120 is a part that is fixedly installed on the sidewalk. The base 120 can be fixedly installed on the sidewalk using anchors, etc.

The column 130 is a structure connected to the base 120, and the light irradiation unit 140 and the light expression unit 150 are arranged at each position in the column 130. In this embodiment, the light irradiation unit 140 and the light expression unit 150 are arranged vertically. However, this is just one example, and it does not matter if their locations change. Accordingly, the scope of the present invention is not limited to the shape of the drawings.

The light irradiation unit 140 is provided on one side of the device main body 110 and is a means of irradiating light to the road adjacent to the crosswalk in order to increase the visibility of the crosswalk.

In this embodiment, the light irradiation unit 140 is applied as a laser light irradiation unit 140 that irradiates a laser beam. At this time, light as a laser beam may be irradiated parallel to the crosswalk over a predetermined length section along the boundary area between the sidewalk and the roadway. Therefore, as shown in Figure 2, a person crossing a crosswalk can have greatly improved visibility of the crosswalk due to the light emitted over a predetermined length along the boundary area between the sidewalk and the roadway. In particular, the effect can be outstanding on dark evenings. Therefore, it can be of great help in preventing traffic accidents.

In this way, the light emitted parallel to the crosswalk over a predetermined length along the boundary area between the sidewalk and the roadway by the light irradiation unit 140 also enters the vehicle driver's field of view, so that he or she is alert not to move the vehicle. can do. Therefore, it can be of great help in preventing traffic accidents.

That is, the controller 190 controls the light irradiation unit 140 to selectively operate on/off in conjunction with the pedestrian traffic light 181 installed on the sidewalk and the driver traffic light 182 installed on the roadway.

For example, when the driver signal light 182 changes to red and the pedestrian traffic light 181 changes to green as shown in FIGS. 2 and 4, the controller 190 turns on the operation of the light irradiation unit 140 to illuminate the corresponding area of the road. Controls the light of the set color to be irradiated to the location. That is, the light irradiation unit 140 irradiates light parallel to the crosswalk over a predetermined length section along the border area between the sidewalk and the roadway. At this time, pedestrians can cross the crosswalk.

And, as shown in FIGS. 1 and 3, when the pedestrian traffic light 181 turns red and the driver traffic light 182 changes to green, the controller 190 turns off the operation of the light irradiation unit 140 to illuminate the road. Controls the light irradiated to a location to disappear or change color. This control is automatically performed in conjunction with the control of traffic lights (181, 182) around the crosswalk.

Next, the controller 190 controls the operation of the light expression unit 150. That is, the controller 190 controls the LED lamp 151 of the light expression unit 150 to emit light of different colors based on the pedestrian signal of the pedestrian traffic light 181.

Specifically, when the pedestrian signal is red, the color of the light emitted from the LED lamp 151 of the light expression unit 150 becomes red, and when the pedestrian signal is green, the light expression unit 150 The color of the light emitted from the LED lamp 151 becomes green, and when the pedestrian signal flashes green, the color of the light emitted from the LED lamp 151 of the light expression unit 150 becomes orange, so that the controller 190 Controls the operation of the LED lamp 151 of the light expression unit 150. Accordingly, pedestrians can safely cross the crosswalk at their own walking speed according to their own signal system.

The controller 190 performing this role may include a central processing unit (191, CPU), memory (192, MEMORY), and support circuit (193, SUPPORT CIRCUIT).

In this embodiment, the central processing unit 191 may be one of various computer processors that can be applied industrially to control the operations of the light irradiation unit 140 and the light expression unit 150 through an organic mechanism.

Memory 192 (MEMORY) is connected to the central processing unit 191. Memory 192 is a computer-readable recording medium that can be installed locally or remotely, for example, in a readily available storage medium such as random access memory (RAM), ROM, floppy disk, hard disk, or any other digital storage form. It may be at least one memory.

The support circuit 193 (SUPPORT CIRCUIT) is combined with the central processing unit 191 to support typical operations of the processor. This support circuit 193 may include a cache, power supply, clock circuit, input/output circuit, subsystem, etc.

In this embodiment, the controller 190 operates the light irradiation unit 140 selectively on/off in conjunction with the pedestrian traffic light 181 installed on the sidewalk and the driver traffic light 182 installed on the roadway. On the other hand, based on the pedestrian signal of the pedestrian traffic light 181, the LED lamp 151 of the light expression unit 150 is controlled to emit light of different colors. This series of control processes are stored in the memory 192. It can be saved in . Typically, software routines may be stored in memory 192. Software routines may also be stored or executed by other central processing units (not shown).

Although the process according to the present invention has been described as being executed by software routines, it is also possible that at least some of the processes according to the present invention are performed by hardware.
