Description

Pedestrian crossing lighting device {ILLUMINATING APPARATUS IDENTIFYING THE CROSSWALK}

The present invention relates to a lighting device for identifying a crosswalk, and more particularly, by installing a lighting source on a road pavement so that pedestrians or drivers can clearly identify a crosswalk even at night or in rainy weather, and lights installed on the road pavement It relates to a crosswalk lighting device that can easily perform replacement and maintenance work on a circle.

In general, crosswalks installed so that vehicles can cross the road are marked on the pavement of the road.

In such a crosswalk, as the traffic system is configured such that ground-type traffic lights for vehicle traffic and pedestrian traffic lights for pedestrian traffic are interlocked with each other, pedestrians cross the road along the crosswalk according to the instructions of the traffic lights.

However, in situations where visibility is not secured, such as at night or during rainy weather, it is not easy to visually identify a crosswalk marked on the road surface.

That is, in a normal crosswalk, the boundary line on both sides is only marked on the road surface, and it is difficult to visually identify the driver of the vehicle as well as the pedestrian if the visibility distance is not secured.

Accordingly, if a driver driving only by looking at ground-type traffic lights is not careful, he may not be able to recognize a pedestrian passing through the crosswalk, and in this situation, a traffic accident may occur at the crosswalk by driving while ignoring the traffic signal.

In particular, since children often ignore the overall road conditions and see only the pedestrian traffic lights and jump into the crosswalk, vehicle drivers driving on the road need to quickly recognize the location of the crosswalk and the presence or absence of pedestrians.

Conventional crosswalks are only marked with paint containing fluorescent materials on the road surface, making it difficult for pedestrians or vehicle drivers to easily identify them, especially when visibility is not secured, such as at night or in rainy weather. There was a problem in that traffic accidents occurred at crosswalks because it was difficult to identify with the naked eye.
