Abstract

The present invention illuminates a crosswalk and a stop line with a lighting unit at the lower part of a signal display unit, thereby allowing the driver to mark the danger around the crosswalk, while securing the visibility of the stopwire, thereby preventing a traffic accident. The present invention relates to a crosswalk illumination device.

Description

[0001] Crosswalk lighting equipment [

The present invention relates to a crosswalk lighting apparatus, and more particularly, to a crosswalk lighting apparatus having a lighting unit at a lower portion of a signal display unit to illuminate a crosswalk and a stop line so that a driver can mark the danger around the crosswalk, The present invention relates to a pedestrian crossing illuminating device for preventing a traffic accident from occurring in a safe manner.

Generally, a pedestrian crossing is displayed on a road on which a pedestrian can safely walk on the road, and a traffic light is installed on a cross pedestrian crossing where a lot of vehicles pass and a lot of pedestrians pass, .

The traffic light includes a green light for allowing the driver to walk and a red light for driving the driver, a yellow light for turning the driver, and a turn signal lamp. When the driver and the pedestrian obey each signal light, safe traffic operation can be performed.

However, if there are no pedestrians passing through the pedestrian crossing, there are people who run across the pedestrian crossing, ignoring the stoppage of the traffic light on the pedestrian crossing, More.

However, in the pedestrian crossing, there is not a lighting device such as a streetlight installed in the vicinity, so there are many dark places. In such a place, it is difficult for the driver to easily grasp the pedestrian passing through the pedestrian crossing. Therefore, there is a risk of causing a traffic accident if the driver crosses the pedestrian crossing while ignoring the stop signal of the traffic light installed on the crosswalk.

FIG. 1 is a configuration diagram of a signal lamp to which the present invention is applied, and FIG. 2 is an exploded perspective view of a lighting unit and fixing means of the present invention.

The present invention is characterized in that a column 11 is constituted and a horizontal beam 12 extending horizontally is formed on one side of the column 11 and is fixed to an end of the horizontal beam 12, A traffic signal lamp 10 including a signal indicator 13 of a yellow light and a turn signal lamp is integrally provided at the lower portion of the signal display unit 13 to constitute a lighting unit 100 for irradiating light to a crosswalk and a stop line A sensing sensor 200 for sensing the brightness of the vicinity of the traffic light 10 at a position close to the illuminating unit 100 and a controller 200 for receiving the sensing signal of the sensing sensor 200 and controlling the illuminating unit 100 (300), which will be described in more detail as follows.

The illumination unit 100 is formed of any one of a light emitting diode (LED) light source and a laser light source.

The control unit 300 receives the data value sensed by the sensing sensor 200 and turns off the illumination unit 100 if the brightness is higher than a predetermined brightness and turns on the illumination unit 100 when the brightness is lower than a predetermined brightness.

And fixing means 400 for fixing the illumination unit 100 to the lower portion of the signal display unit 13.

The fixing unit 400 includes a pair of ribs 410 having a shaft hole 411 formed at a lower portion of the signal display unit 13 and a rotation guide slot 420 And a center shaft 430 protruding from both sides of the illumination unit 100 and coupled to the shaft hole 411. The rotation shaft 420 is formed on both sides of the illumination unit 100, And a nut 450 having a shaft 440 and fixing the center shaft 430 to the rib 410 is provided.

Hereinafter, the combination and operation of the present invention will be described in detail.

First, as shown in Figs. 3 to 5, A traffic signal lamp 10 is installed at a boundary between a road and a road where a crosswalk is installed and is formed with a vertical support 11 and a horizontal beam 12 horizontally installed on the upper side of the support 11, At the end of the horizontal beam 12, a signal display unit 13 formed of a green light, a red light, a yellow light, and a turn signal lamp is provided.

A lighting unit 100 is installed below the signal display unit 13 to illuminate a crosswalk and a stop line.

The illumination unit 100 is integrally fixed to the lower end of the signal display unit 13 and emits light using either a light emitting diode (LED) light source or a laser light source.

In addition, the illumination unit 100 may be fixed to the lower portion of the signal display unit 13 through a fixing unit 400.
