KR-20260000621-U - Signal lamp for school zone

Abstract

The present invention is designed to prevent drivers from unintentionally violating the speed limit and speeding at crosswalks or intersections within a child protection zone by displaying the speed limit as a number on the traffic light itself. In a traffic light in which a three-color traffic light (S) is suspended from the lower part of a cantilevered traffic light pole (C) erected in front of a crosswalk or intersection in a child protection zone, the traffic light (S) includes three individual traffic lights (R, Y, G) consisting of red, green, and yellow. Each of the three individual traffic lights (R, Y, G) is designed to light up only with the numbers for red, green, and yellow, respectively. When the green traffic light (G) is lit, the speed limit is displayed so that the driver can drive slowly while looking only at the green traffic light (G) and not violate the speed limit. Additionally, the yellow or red traffic lights (Y, R) are also lit up only with numbers so that the driver can stop at the crosswalk or intersection and recognize that it is a child protection zone.

1. In a traffic light in which a three-color traffic light (S) is suspended from the lower part of a cantilevered traffic light pole (C) erected in front of a crosswalk or intersection in a child protection zone, The above traffic light (S) includes three individual traffic lights (R, Y, G) consisting of red, green, and yellow, and each of the three individual traffic lights (R, Y, G) is designed to light up only with red, green, and yellow numbers, so that when the green traffic light (G) is lit, the speed limit is displayed so that the driver can drive slowly while looking only at the green traffic light (G) and not exceed the speed limit, and the yellow or red traffic lights (Y, R) are also lit only with numbers so that the driver can stop at a crosswalk or intersection and recognize that it is a child protection zone.

Description

Signal lamp for school zone Signal lamp for school zone The present invention relates to a traffic light exclusively for child protection zones, wherein the speed limit is displayed as a number on the traffic light itself, thereby preventing drivers from unintentionally violating the speed limit or speeding or running a signal at crosswalks or intersections within child protection zones. In a school zone, all drivers must drive at a speed limit of 30 km/h or less. As shown in FIG. 1, this school zone is equipped with various signs, including a sign (10) indicating a "school zone" and a traffic sign (20) indicating "slow down." Additionally, traffic lights (30), crosswalk signs (40), and signs (50) indicating speed enforcement cameras are installed in succession to encourage drivers to pay attention. However, there was a problem in that the drivers felt fatigued due to these complex and numerous signs, and their gaze was diverted to the various signs, resulting in a situation where they could not look directly at the traffic lights. In other words, in child protection zones, there is a problem of distraction as one must look at countless signs and simultaneously check for changes in signals, which often leads to unintentional signal violations or speeding violations. In the drawing, symbol 60 is a composite sign installed adjacent to the road of a child protection zone, displaying the speed limit, child protection zone, and crosswalk markings together. Consequently, as drivers become distracted by looking at various signs while passing through child protection zones, situations frequently occur where they violate traffic signals or speed limits. This is because drivers typically drive and stop while only looking at traffic lights (30), and speed limit signs are separate from traffic lights (10). As a result, drivers are unfairly fined for slightly exceeding the speed limit by 30 km/h even though they drive at a low speed while only looking at traffic lights and fail to recognize the speed limit signs. Therefore, complaints are increasing that this is an unfair system that unilaterally regulates the driving habits of drivers who drive while keeping their eyes on the road ahead. In addition, as shown in Fig. 1, there are countless signs in the child protection zone, so the cost of installing them is considerably high and a significant amount of manpower is required for their management. It is also pointed out that this causes drivers to have their eyes distracted or their traffic lights obscured, leading to signal violations or speeding violations. Patent documents 1 and 2 disclose a speed limit display device for notifying a driver of the speed limit, but since this is separate from traffic lights installed at crosswalks or intersections, it is often missed if not observed carefully. Figure 1 is a photograph of the installation state of a conventional child protection zone sign. FIG. 2 is a diagram showing the installation state of a traffic light according to one embodiment of the present invention. Hereinafter, preferred embodiments that do not limit the present invention will be described in detail with reference to the attached drawings. FIG. 2 illustrates a traffic light (S) dedicated to a child protection zone according to one embodiment of the present invention. This is a three-color traffic light (S) suspended from the lower part of a cantilevered traffic light pole (C) erected in front of a crosswalk or intersection in a child protection zone. The traffic light (S) includes three individual traffic lights (R, Y, G) consisting of red, green, and yellow. Each of the three individual traffic lights (R, Y, G) is designed to light up only with the number 30 for red, green, and yellow, respectively. When the green traffic light (G) is lit, the speed limit is displayed as 30, allowing the driver to drive slowly while looking only at the green traffic light (G) and avoid exceeding the speed limit. Additionally, since the yellow or red traffic lights (Y, R) are also designed to light up only with the number 30, drivers can stop at the crosswalk or intersection and recognize that it is a child protection zone. The traffic light (S) dedicated to a child protection zone according to the present invention is designed so that the speed limit is displayed on each individual traffic light (R, Y, G), thereby allowing the driver to immediately recognize the speed limit while looking at the traffic light and preventing unintentional violation of the speed limit. Ideally, each of the individual signal lights (R, Y, G) is configured to display the number 30 using a plurality of LED elements (2), and since the number 30 itself is illuminated in red, green, or yellow, the same visibility can be ensured during the day as well as at night. In the embodiment illustrated in FIG. 2, three individual traffic lights are installed horizontally below a cantilevered traffic light pole, but the present invention is not limited there
