Traffic light with time indicator

Abstract

The invention discloses a traffic light with a time indicator. In the invention, red, yellow and green LED lights are arranged in a spaced manner to form a triangular arrow light; the red, yellow and green LED lights on the outer profile of the arrow light are connected with a red-yellow-green color change control circuit; and the red, yellow and green light on the inner side of the outer profile of the arrow light are connected with a red-yellow-green gradual change control circuit. The arrow light is provided with a lambdoidal pattern light formed by arranging red, yellow and green LED lights in a spaced manner, the red, yellow and green LED lights of the lambdoidal light are connected with the red-yellow-green color change control circuit. The arrow light is also provided with a bicycle pattern light formed by arranging red, yellow and green LED lights in a spaced manner, the red, yellow and green LED lights of the bicycle pattern light are connected with the red-yellow-green color change control circuit. The traffic light with a time indicator can give a 'go' or 'stop' signal for vehicles or pedestrian in a direction and can also display the time gradual change interval of the 'go' or 'stop' signal. Thus, the clear, defined and quick indication problem of traffic lights at crossings can be solved effectively, conveniently and quickly.

Description

technical field [0001] The invention belongs to traffic signal lights, in particular to a traffic light with time indication. Background technique [0002] Urban streets command traffic lights, the earliest is to use red, yellow and green lights, and cooperate with the corresponding crossing traffic rules to command the traffic of pedestrians and vehicles at street intersections. People follow the principle of stopping at red lights, going at green lights and going at yellow lights, or listening to the principle of prudent walking and the rules of turning left and right. With the progress of society, the concept of time is enhanced. Can not adopt general crossing traffic rules for different crossings on the other hand, special crossing needs to have the rule of going straight ahead and turning left and right. In addition, people hope that the time interval length of "stop" or "going" and the alternate time of "stopping" or "going" of traffic lights (including pedestrians i...

AI Technical Summary

Problems solved by technology

[0003] To sum up the above: the traffic lights with arrows can only tell people which direction to "stop" and which direction to "go" for pedestrians or vehicles, and cannot indicate the length of time interval between "stop" or "go"; It can only show the length of time for changing traffic lights, and cannot clearly indicate which direction to go or stop

As a result, there are various traffic lights at present, which bring confusion to vehicles and pedestrians crossing the intersection, making it difficult for people to adapt

Therefore in any case the traffic lights of single arrows or the traffic lights of single rectangular gradient light strips and digital lights can not meet the needs of traffic command at modern traffic busy intersections
