Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a traffic signal having a traffic signal main body and a lighting time display device for displaying the lighting time of a red signal light of the traffic signal main body.

The lighting hours of traffic signal lights are not constant across the country, but vary by ward. For this reason, drivers are frustrated because they do not know how long it takes for the traffic signal to change from red to green, and this frustration is one of the causes of accidents.

Furthermore, the signal lights of traffic signals are extremely difficult to see when the sun shines in the morning or evening, and it is often difficult to tell whether the signal light is a red signal light or a blue signal light.

In addition, when starting at an intersection, preparations are usually made when the signal light of the adjacent traffic signal that intersects with the vehicle's direction of movement changes from a blue signal light to a yellow signal light. Some drivers start to move off gradually.
This is done in anticipation that the traffic light in the direction of travel will soon turn green.

However, although this is not as much of a problem at simple intersections such as crossroads, it can cause accidents at complex intersections such as three-way or five-way intersections. This is because, in such complex intersections, when the adjacent traffic signal lights red, the next traffic light in the direction of travel does not always light green. In such cases, especially if it is your first time passing through the intersection,
There is a high risk of starting the vehicle incorrectly and causing a collision.

The present invention was developed in view of the above, and at the same time that the signal light on the traffic signal body turns red, all the indicator lights of the lighting time display device attached around the traffic signal body turn on, and the signal light changes to blue. To provide a traffic signal that solves all of the above points by displaying the state of progress over time by turning off the lights one by one until the traffic lights change. That is.

However, the gist of the present invention is as follows.

A traffic signal having a traffic signal main body 1 and a lighting time display device 3, wherein the lighting time display device 3 includes a display frame 4 having a groove.
and a required number of indicator lights 5, an indicator light storage chamber 7 is formed in the groove of the display frame 4 by the partition wall 6, and the indicator light 5 is accommodated in the indicator light storage chamber 7. The lighting time display device 3 is installed around the traffic signal main body 1, and all the indicator lights 5 are turned on at the same time as the red signal light of the traffic signal main body 1 is turned on, A traffic signal characterized in that the indicator lights are sequentially turned off one by one in accordance with the time from turning on to turning off the red signal lights.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a partially cutaway perspective view of the lighting time display device of the present invention, Fig. 2 is an enlarged view of part A in Fig. 1, and Fig. 3 is a view taken along the line - in Fig. 2. FIG. 4 is a perspective view of the entire invention.

In the figure, 1 is a traffic signal main body, 1a is a blue signal light, 1b is a yellow signal light, and 1c is a red signal light. Reference numeral 2 denotes a light-shielding wall of the traffic signal main body 1.

Reference numeral 3 denotes a lighting time display device, which displays the lighting time of the red signal light of the traffic signal body 1.

The lighting time display device 3 includes a display frame 4 having a groove and a required number of indicator lights 5, and an indicator light storage chamber 7 is formed in the groove of the display frame 4 by a partition wall 6. , the indicator light 5 is housed in the indicator light storage chamber 7.

Furthermore, the lighting time display device 3 is attached around the traffic signal main body 1.

In addition, all the indicator lights 5 are turned on at the same time as the red signal light of the traffic signal main body 1 is turned on,
The indicator lights are turned off one by one in response to the time from when the red signal lights are turned on until they are turned off.

Further, the indicator light 5 may be a red electric light or a white electric light. In addition, when using a white electric lamp, it is desirable to attach a red transparent plate 8 so as to cover the front surface of the indicator lamp as shown in the figure.

Also, when turning off the indicator light 5, set the start and end positions of the light off to the diagonally lower position of the red signal light,
That is, the positions 5a and 5b in FIG. 4 are desirable.

The present invention has the above-mentioned configuration and operation, and uses a lighting time display device to display the elapsed lighting time of the red signal light on the traffic signal body, and to indicate how much time has passed for the red signal light to change to a blue signal light. It is something that can be predicted.

Therefore, drivers can clearly know how long they have to wait for the red signal light to change to a green signal light, which eliminates the frustration they experienced in the past and allows them to smoothly prepare for departure. It is possible.

In addition, at complex intersections, even if the adjacent traffic signal changes from red to blue,
If you look at the traffic signal in the direction you are traveling and find that the indicator light is only partially turned off, you will know that the signal light has not changed to green yet, which prevents you from accidentally starting the vehicle.

In addition, since the indicator lights go out one by one, they are extremely easy to see, just like flashing lights, etc. Therefore, even when the signal lights are illuminated by the morning or evening sun, drivers can easily see that the red signal lights are currently on. can be visually recognized.

Furthermore, since the indicator lamps are each housed in the indicator lamp storage chamber formed by the partition wall, the light from each indicator lamp does not leak into the surroundings. Therefore,
The part of the indicator light that is turned off is not affected by the light of other indicator lights that are on, and becomes completely dark.
This makes it possible to clearly notify the driver that the lights are going out.

For these reasons, the present invention greatly contributes to the reduction of traffic accidents.
