Description

{ILLUMINATING APPARATUS IDENTIFYING THE CROSSWALK}

The present invention relates to a lighting device for identifying a pedestrian crossing, and more particularly, to a pedestrian or a driver who can clearly identify a pedestrian crossing even at night or rainy day by installing an illumination source on the road pavement surface, To a crosswalk illumination device capable of easily performing a replacement and maintenance work for a circle.

Generally, a crosswalk installed to cross the road on which the vehicle is traveling is indicated on the pavement side of the road.

In this pedestrian crossing, the traffic system is configured so that the traffic light for the traffic of the vehicle and the pedestrian traffic light for the traffic of the pedestrian interlink with each other, so that the pedestrian crosses the road along the pedestrian crossing in accordance with the signal light.

However, it is not easy to visually identify the pedestrian crossing on the road when the visibility is not secured, such as during nighttime or rainy days.

In other words, the ordinary crosswalk is only the extent that both side edges are displayed on the road surface, and it is difficult to visually identify pedestrians as well as the driver of the vehicle unless the visual distance is secured.

As a result, pedestrians passing through the pedestrian crossing may not be recognized unless the driver who watches and operates the pedestrian traffic light is careful. In such a situation, a traffic accident on the pedestrian crossing may occur by ignoring the traffic signal.

In particular, children often jump into crosswalks by ignoring overall road conditions and seeing pedestrian traffic lights. Therefore, drivers of the roads need to be aware of pedestrian crossings and the presence of pedestrians.

Conventional pedestrian crossing is merely a paint containing fluorescent material on the road surface of the road, and is easily distinguished from pedestrians or vehicle drivers. In particular, when the visibility distance is not secured at night or rainy There is a problem that it is difficult to distinguish the vehicle from the naked eye and a traffic accident occurs on the crosswalk.
