A third object of the present invention is to reduce the maintenance cost by sensing the amount of light around the traffic light and adjusting the brightness of the traffic light consisting of LEDs according to the detection result.

The fourth object of the present invention is to warn the driver not to enter the intersection when the warning (green) light is first turned on by warning that the stop (red) light is turned on by the green light signal before changing from the progress (green) light to the warning (no light) light. It is to provide a traffic signal system that can call the attention of.

The above-mentioned green-green lighting means that the left signal light is green, the right signal light is green or the left signal light is green, and the right signal light is green, and the same is true of non-no light and red light.

In addition, the green glow lighting means that the left signal light is green, the right signal light is yellow or the left signal light is yellow, and the right signal light is green.

As described above, the reason for the configuration of one-color two-ball equalization method (green green, no-no, red, green) is to emphasize one color to focus the eyes, reduce misunderstanding or confusion caused by other colors, To increase the visibility and readability of the driver. That is, by arranging conventional three-color three-light, three-color four-light on one side is to improve the disadvantage of poor visibility.

In addition, the present invention has the advantage of being able to reduce the size of the conventional three-way traffic light by being composed of two spheres to reduce the damage from natural disasters of typhoons and rainstorms.

Although the present invention has been described as a two-beam signal light, when the left turn signal is added, the left signal light consisting of a green LED may be further included in the traffic light. The U-turn signal can also be configured in the same manner.

At this time, by transmitting the detected light amount result value to the LED brightness control unit 170 to adjust the brightness of the LED to display the color of the traffic light.

As described above, the reason for adjusting the brightness of the LED is that when the driver is facing the sun or facing the front and driving the vehicle, it is impossible to confirm whether the traffic light is displaying red or green, and the vision is not correct. When a bad driver sees a traffic light from a distance, it becomes difficult to see.In this case, the brightness of the LED is increased when the sunlight is bright and the brightness of the LED is lowered when the sunlight is not bright so that the driver can see clearly and turn on the LED at the same time. It is to save the maintenance cost by reducing the power for the.

2 is a flow chart of a two-way traffic light signal method according to an embodiment of the present invention.
