[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a traffic light that switches to a different signal at predetermined time intervals.

[0002]

[Prior Art]

 As a traffic light that switches to a different signal every such predetermined time, for example, there is a traffic light installed at a road intersection or the like. This traffic signal is equipped with, for example, a blue signal, a yellow signal, and a red signal. The blue signal, the yellow signal, and the red signal are switched and turned on in that order at predetermined time intervals, so that the traffic of vehicles and pedestrians can be controlled. Is being done.

[0003]

[Problems to be solved by the device]

 By the way, the drivers and pedestrians of vehicles are often stopped by turning on the red traffic light and switch from the red traffic light to the green traffic light, but it is not possible to know the time to switch from the red traffic light to the green traffic light. You may need to use your nerves to switch between traffic lights, and you may be frustrated by not knowing how long the red traffic light will continue, or you may experience delays in starting and passing without noticing the switching to the green traffic light.

Further, the green signal is switched to the yellow signal, and further, the yellow signal is switched to the red signal, but the process proceeds due to an erroneous judgment of the lighting of the yellow signal without knowing the time when the red signal lights up to make the vehicle inaccessible. It may stop and cause a rear-end collision.

[0005] Furthermore, the pedestrian signal is made to function as a yellow signal by blinking a green signal, and the blinking of the blue signal is switched to a red signal. It is possible for a person to rush and fall while trying to force a cross, and to prevent wasting time by giving up when the green light begins to flash.

The present invention has been made in view of the above point, and by displaying the remaining time until the signal is switched, it is possible to effectively contribute to traffic safety by eliminating the annoyance of a driver or a pedestrian. The purpose is to provide a traffic light that can.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is such that a traffic light that switches to a different signal at predetermined time intervals is provided with a clock, and the time remaining until the signal is switched is displayed on this clock. Is characterized by.

[0008]

[Action]

 In this device, a different signal is switched at every predetermined time, and the remaining time until the lighted signal is switched is displayed on the clock, so that, for example, a driver or a pedestrian can know the switching of the lighted signal. be able to.

【Example】

 An embodiment of the traffic light of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic diagram of a traffic light, and FIG. 2 is a diagram showing a relationship between a lighting time of a signal and a remaining time display of the signal.

Reference numeral 1 is a traffic signal installed at an intersection of roads, etc., and a display panel 2 of this traffic signal 1 is provided with a green signal 3, a yellow signal 4 and a red signal 5 in order from left to right, and at predetermined time intervals. , Blue signal 3, yellow signal 4 and red signal 5 are switched to signals of different colors.

A clock 6 is provided below the display panel 2 of the traffic light 1, and the clock 6 displays the remaining time until the displayed signal is switched.

The lighting of the green signal 3, the yellow signal 4 and the red signal 5 of the traffic light 1 and the display of the clock 6 are controlled by the central control unit 7, respectively. The control by the central control unit 7 is shown in FIG. ing. The central control unit 7 centrally controls a large number of traffic lights 1. In this traffic light 1, the green signal 3 lights for t1 hours, the yellow traffic light 4 for t2 hours, and the red traffic light 5 for t3 hours. As for the display of the remaining time until the signal is switched by the clock 6, when the green signal 3 is lit, the remaining time of the signal obtained by adding the lighting time of the blue signal 3 and the lighting time of the yellow signal 4 is displayed. When the yellow traffic light 4 is switched to the red traffic light 5 and is turned on, the time remaining until the red traffic light 5 is switched is displayed on the clock 6. Further, when the red signal 5 is switched to the blue signal 3 and the light is switched on, the remaining time of the signal obtained by adding the lighting time of the blue signal 3 and the lighting time of the yellow signal 4 is displayed, and the above-described control is repeated thereafter.

In the remaining time display method until the signal is switched by the clock 6, it is preferable to display a countdown every predetermined time, for example, 40 seconds, 30 seconds, 20 seconds, 10 seconds, 9 seconds, 8 seconds, 7 seconds. , 6 seconds, when the remaining time until the signal is switched is long, it is preferable to display at 10-second intervals, and when the remaining time for the signal is short, it is preferable to switch the display in units of 1 second for easier viewing.

Therefore, the driver or pedestrian of the vehicle is supposed to stop at the lighting of the red traffic light 5 and switch from the red traffic light 5 to the green traffic light 3. However, the remaining time until the red traffic light 5 switches on the clock 6 Since the time is displayed, the time to switch from the red traffic light 5 to the green traffic light 3 is known, and drivers and pedestrians do not have to constantly use their nerves to switch the traffic light. In addition, there will be no delay in starting or passing without noticing the change to the green light 3.

Further, the green signal 3 is switched to the yellow signal 4, and further, the yellow signal 4 is switched to the red signal 5, but the remaining time from the lighting of the blue signal 3 to the lighting of the red signal 5 is displayed on the clock 6. As a result, it is possible to know the time when the red traffic light 5 is turned on and the vehicle cannot pass, and it is possible to prevent the occurrence of an accident because there is no error in the lighting decision of the yellow traffic light 4.

As described above, by displaying the remaining time until the signal is switched on the clock 6, the driver and the pedestrian are not irritated, and the traffic safety can be more effectively contributed.

In a pedestrian traffic light, a blinking green signal causes the yellow signal to function, and the blinking green signal switches to a red signal. However, by displaying the remaining time when the green signal lights up to a red signal is displayed on the clock. , It is possible to prevent pedestrians from forcibly crossing, rushing, running, and falling, and wasting time.

FIG. 3 is a schematic diagram of another embodiment of the traffic light. This embodiment is constructed in the same manner as the traffic light 1 shown in FIGS. 1 and 2, except that a timepiece 6 is incorporated into the display board 2 of the traffic light 1, and a blue signal 3, a yellow traffic light 4 and a red traffic light 5, and a clock 6 are provided. Are integrated.

4 and 5 show another embodiment of the traffic light, FIG. 4 is a schematic view of the traffic light, and FIG. 5 is a sectional view of the traffic light. The traffic light 1 of this embodiment is one in which a signal light 8 and a clock 6 are incorporated in a display board 2. This signal lamp 8 has a cylindrical three-color filter 10 rotatably provided around a light source 9 which is divided into blue 10a, yellow 10b, and red 10c, and light from the light source 6 passes through a light shielding plate 11. Is guided to the lens 12.

Therefore, in this traffic light 1, the three-color filter 10 is instantaneously rotated to switch the signal, and the rotation of the three-color filter 10 is stopped to output the blue signal, the yellow signal, and the red signal for a predetermined time. Turn on the light. By using such a signal light 8, a space for arranging a green signal, a yellow signal, and a red signal is secured more than in a parallel arrangement, and a large signal light 8 can be attached to a limited display panel 2. Visibility is improved.

In each of the above-mentioned embodiments, a digital type timepiece is used, but an analog type timepiece may be used.
