Description

{Crosswalk lighting control}

The present invention relates to a pedestrian traffic light control device for communicating with a traffic signal controller for controlling a vehicle traffic light and a pedestrian signal light provided on a road map, and controlling a light projecting light separately provided according to a received gait signal.

Generally, the road is provided with a pedestrian crossing for pedestrian crossing.

These pedestrian traffic lights include pedestrian traffic lights that allow pedestrians to recognize the possibility of crossing, and driver traffic lights that allow the driver to recognize the crossing traffic.

In other words, the pedestrian traffic light is installed on the pedestrian crossing so that pedestrians waiting in India can easily recognize the pedestrian traffic light, and the driver's traffic light is provided in a pillar installed in India, so that the driver of the vehicle So that it is positioned vertically above the crosswalk.

However, since the above-described traffic lights merely perform signal functions, the driver can not accurately grasp the situation of the pedestrian crossing at a remote place in the night or in bad weather, so that pedestrians passing through the pedestrian crossing without being aware of the pedestrian crossing, There is a problem of.

That is, when the driver driving the vehicle observes the front of the vehicle and observes the roadway according to the external environment (at nighttime and when the weather is bad), the driver can not watch the driver's traffic light located at a relatively high position, There is a problem that it is often not recognized and causes a traffic accident.

Accordingly, in recent years, a separate lighting facility for illuminating the crosswalk at night or in bad weather has been proposed for the above problems and installed in the crosswalk.

In recent years, a lighting device has been installed to illuminate the crosswalk at night so that the driver can more easily identify the presence of pedestrians crossing the pedestrian crossing in the dark night environment.

Korean Patent No. 10-1104227 (entitled " Pedestrian Lights ") is one of the above illuminating facilities, and the illuminating device includes a base fixed to the ground as described in the publication; A case formed in a hollow shape and fixed to the upper portion of the base, and having an opening at an upper end thereof; A light emitting unit assembly inserted into the opening; A protrusion formed by bending a part of the body of the case in the longitudinal direction of the case and having a cross-sectional shape protruding inward from the case in a pipe shape; And a cap covering and sealing the upper portion of the case.

However, the conventional light for pedestrian crossing is merely an illuminating light, and the driver is not configured to recognize the walking time remaining for the pedestrian signal lamp. In other words, although a device for notifying a remaining time is provided in a recently installed pedestrian signal lamp, it is difficult for the driver to recognize it because the remaining time notification device is for pedestrians. Even if a remaining time notification device is installed in a traffic light It was also hard to recognize due to low visibility and carelessness. From the viewpoint of pedestrians, it is difficult to precisely measure the remaining time, but it is difficult to precisely match the speed. In such a case, the driver could see the traffic light only without seeing the pedestrian walking late.

In order to solve the above problems, the present invention provides a control system for controlling a floodlight or the like so as to illuminate a crosswalk at night so that a vehicle driver can more easily identify the presence or absence of a pedestrian crossing the crosswalk in a nighttime dark night environment And it is an object of the present invention to provide a pedestrian traffic light control device.
