Description

Traffic signal device with auxiliary traffic light {TRAFFIC SIGNAL DEVICE WITH AUXILIARY TRAFFIC LIGHTS}

The present invention relates to a traffic signal device having an auxiliary traffic light, and more particularly, by installing an auxiliary traffic light interlocked with a main traffic light on a cross beam coupled to a post to increase driver's traffic signal visibility, as well as the cross beam. relates to a traffic signal device having an auxiliary signal light in which an auxiliary signal light can be easily installed by forming a seating groove into which an auxiliary signal light can be embedded and a wire guide groove into which a cable connector of the auxiliary traffic light can be installed.

In general, the purpose of a means of transport, which is a car, is to promote convenience for users. For this purpose, automobiles are an essential element that is indispensable for one's life as well as social life beyond the level of a simple means of transportation, and its proportion is increasing day by day.

Riding on this social trend, the number of cars owned continues to increase, and in our case, it has long since exceeded 10 million.

As described above, as the number of cars owned increases day by day, traffic lights have been developed to more effectively control the traffic flow in a situation where it is impossible to control the traffic flow with manpower.

These traffic lights can be divided into traffic lights that control the flow of vehicles and pedestrian traffic lights that control the flow of pedestrians. Traffic lights constructed in this way can be said to be a very useful technology in terms of functionality in securing the safety of pedestrians as well as vehicles by effectively controlling the flow of traffic.

On the other hand, the traffic lights as described above indicate traffic conditions in colors for safe traffic order, and the colors indicated by the traffic lights are composed of three colors of red, green, and yellow. In the traffic lights configured like this, red (red light) is indicated as a stop signal, green (green light) as a progress signal, and yellow light as a caution, but is also used in road traffic to mean a detour.

As described above, traffic lights for vehicles are generally composed of supports installed upright on the roadside of intersections or crossings, and crossbeams installed in a transverse direction from the supports to the road direction to support the traffic lights.

However, it often happens that the driver cannot see the signal instruction depending on the situation with only the traffic light. For example, there is a situation in which a signal indicated on a display of a traffic light is obscured due to complexity around a traffic light, such as a telephone pole erected on the side of a road or a street tree.

In particular, there are many curved roads in Korea, and at this time, drivers sometimes do not recognize the presence or situation of traffic lights because the traffic lights are obscured by the curved roads from afar, and sometimes accidents occur. Furthermore, in the dark night, there are cases in which the red signal is not distinguished from the headlights of the vehicle, and thus an accident may occur.

In view of these problems, a "wireless recuperative traffic light supporter (Republic of Korea Patent No. 1214542)" has been proposed.

However, this prior art has a problem in that two traffic lights are installed, so installation costs are high, and the bending of the cross beam connected to the post occurs due to the weight of the traffic light.
