The present invention relates to a crosswalk sign, and more particularly, by forming a crosswalk character, a crosswalk figure, and a pedestrian figure using a display LED module, thereby increasing identification and providing an illuminated LED module at a distance or at night. In order to serve as a street lamp at night, the present invention relates to a pedestrian crossing signboard having a structure capable of preventing a short circuit or damage from the outside caused by rainwater on a PCB board and an LED module provided therein.

In general, pedestrian crossing signs are used by pedestrians crossing the roadway to draw stop lines on roads, or by installing upright signs with figures or letters marking pedestrian crossings. To let them pass.

However, a crosswalk sign painted on the road surface or a crosswalk sign painted on a steel plate or with a figure or text indicating a crosswalk is easy to identify during the day, but at night the headlights of the vehicle are close to the crosswalk, so It is difficult to accurately identify its location and whether or not a pedestrian is crossing right before it is illuminated.

Therefore, in such a situation, when the vehicle is close and checks the crosswalk, the driver does not calmly cope with the sudden traffic situation and causes a casualty.

In the place where a traffic light or a street lamp is installed around the crosswalk, the driver can easily recognize the location of the crosswalk, but it is difficult to recognize the presence of the crosswalk at a long distance and the driver does not pay attention. If you do not pass easily.

On the other hand, in recent years, a standing lighting signboard has been set up on the center line of the road adjacent to the crosswalk area line to draw the attention of the driver. However, the lighting signboard is installed on the road on which the vehicle is driven, so the power supply is extremely limited and the driver There were many cases of sudden braking or even colliding with a lit signboard by mistaken as an unauthorized crosswalk, and the effect of preventing accidents by informing the driver of the presence of a crosswalk was very low.

In addition, the conventional pedestrian crosswalk sign was provided with a fluorescent lamp inside the sign to increase visibility at night to inform the night driver the presence of the crosswalk, but such a common fluorescent lamp had a lot of power consumption problems, day and night fluorescent lights There were inconveniences such as having to light up repeatedly.

On the other hand, in order to improve the nighttime identification of the crosswalk on the road should be provided with a separate street light to illuminate the crosswalk, which was a problem that causes waste in the installation cost and maintenance cost.

The present invention for solving the problems as described above, First, by providing a crosswalk character, the crosswalk figure and the pedestrian figure using the display LED module to provide a crosswalk sign that can be easily identified by the driver at a distance. The purpose is.

Second, an object of the present invention is to provide a pedestrian crossing sign that can serve as a street lamp function at the same time as having a lighting LED module that can serve as a street lamp at the bottom of the sign.

Third, an object of the present invention is to provide a pedestrian crossing sign to increase visibility by turning on an LED module at night or in rainy weather by having an optical sensor switch detecting a constant brightness condition.

Fourth, an object of the present invention is to provide a crosswalk sign having a large power saving effect by using a high brightness LED module.
