[0033] See attachedfigure 1 , two groups of two traffic signal light modules arranged side by side to display traffic signals in two traffic directions. When the left-turning green light and the straight-going green light, the green arrow 5 moves continuously towards the direction that the vehicle is allowed to travel, that is, the left-turning traffic signal light The green arrow 5 shown moves to the left, and the green arrow 5 shown by the straight traffic signal light moves upward, indicating that the left turn direction and the straight direction are green lights to allow vehicles to pass, and the vehicles can travel in the direction indicated by the arrow.

[0034] See attached figure 2 Two groups of traffic signal light modules are arranged side by side to display traffic signals in two traffic directions.

[0040] See attached Figure 6 , two groups of two traffic signal light modules arranged side by side to display traffic signals in two traffic directions, and equipped with a digital remaining time display module, the driving circuit is electrically connected to the LED dot matrix for lighting the LED A matrix of dots to form a numerical symbol for displaying the remaining time to switch to the next signal (yellow light). When the left-turning green light and the straight-going green light, the green arrow 5 moves continuously toward the direction that the vehicle is allowed to drive, that is, the green arrow 5 displayed on the left-turning traffic signal light moves to the left, and the green arrow 5 displayed on the straight-going traffic signal light moves upward, indicating that the left The turn direction and the straight direction are green lights to allow vehicles to pass, and vehicles can travel in the direction indicated by the arrow.

Abstract

A dynamic traffic signal lamp comprises a lamp pole, a signal lamp frame, a traffic signal lamp module, a controller module, a communication module and a power module. The dynamic traffic signal lamp is achieved by adopting a light emitting diode dot matrix. Running allowing or forbidding can be judged according to colors of red, yellow and green and can also be judged according to the dynamic state of the traffic lamp, and namely a green arrow moves towards the running allowing direction when the lamp is green, a red arrow is static and points to the running forbidding direction when the lamp is red, and a yellow arrow flickers alternatively when the lamp is yellow. According to the dynamic traffic signal lamp, by slightly changing the display portion of an existing traffic light, the problem that the existing traffic light can not be recognized by the crowd having dyschromatopsia can be solved.

Description

technical field [0001] The invention relates to a traffic signal lamp and a display method thereof, in particular to a dynamic traffic signal lamp and a display method thereof. Background technique [0002] Traffic lights, also known as traffic lights or traffic lights, play a major role in traffic management in urban life. It has become an important equipment guarantee for the travel order and road safety of hundreds of millions of pedestrians. Although the existing traffic lights have been accepted by most of the social groups, they are still not applicable to color-weak and color-blind groups. With the development of the economy, cars have gradually entered thousands of households and become a common travel tool for people. However, the "Regulations on Application and Use of Motor Vehicle Driving Licenses" stipulates in color discrimination: no red and green color blindness. It can be seen that, due to the lack of traffic lights, the right to drive is deprived of a part ...
