Description

Smart pedestrian crossing luminaire}

The present invention relates to a smart crosswalk luminaire, and more particularly, to a smart crosswalk luminaire that can protect pedestrians by irradiating a light source according to the operation of the traffic light installed on a traffic light provided in the crosswalk.

In modern society, due to rapid urbanization, many people live in urban areas, but the city has a large population and many vehicles come and go, causing casualties from traffic accidents every day.

In particular, in areas with a large floating population, there is a high risk of traffic accidents because a lot of people and vehicles come and go. It induces students to go to school safely, installs crosswalks throughout the road, and gives priority to pedestrians, but in dark nights, unfortunate accidents frequently occur due to drivers who do not recognize pedestrians walking across the crosswalk.

Most of these traffic accidents are caused by the driver's careless driving or the students' carelessness. Young students, such as elementary school students, have less attention and situational awareness than adults, so they are not fully aware of the situation where vehicles are passing on the road. A traffic accident occurs while crossing the road without permission.

In addition, accidents caused by the driver's careless driving frequently occur not only in the school zone but also in the general area, which is caused by not recognizing that a crosswalk is located on the road or neglecting to look ahead.

In addition, elderly elderly people may not be able to accurately recognize crosswalks when the road around the road is dark due to night or rain due to incomplete vision and hearing, and they may suffer a traffic accident while crossing without permission.

Therefore, not only the driver but also the pedestrian must accurately recognize the crosswalk on the road and walk and stop according to the traffic signal of the crosswalk to prevent traffic accidents.

Crossings that allow pedestrians to cross the road can be arranged on each road, and crosswalks are drawn on the roads on which such crossings are arranged so that not only pedestrians but also vehicle drivers can easily identify them.

However, the visual stimulus of the crosswalk drawn on the road alone is weak, so drivers tend to overlook it easily.

In particular, the signal status of various traffic lights installed on the crosswalk (ie, whether the blue light is on or the red light is on) is easy to identify when the weather is good, but it is often difficult to distinguish depending on the weather conditions.

In addition, although the driver of a vehicle running at high speed must be able to identify the signal state of a traffic light installed at such a crosswalk even from a distance, this problem cannot be solved only with the form of a traffic light according to the conventional method.

On the other hand, the above-described background technology is technical information that the inventor possessed for derivation of the present invention or acquired during the derivation process of the present invention, and is not necessarily known to be known to the general public prior to filing the present invention. .
