Description

Technical Field

[0001] The utility model relates to the field of traffic signal lights, and more specifically, to a modular and expandable traffic signal light. Background Art

[0002] Traffic lights use different colored light signals to tell drivers and pedestrians when to move or stop, thus effectively regulating road traffic order. Especially during peak hours or on congested roads, traffic lights play a more obvious role, allocating and limiting the travel time of vehicles and pedestrians, effectively avoiding traffic congestion and traffic accidents.

[0003] The existing traffic lights usually have a fixed arrangement of lamp units, and it is impossible to choose the corresponding installation method according to the actual situation of the road. Therefore, the application scenarios of a single traffic light are often relatively narrow, and it is not universal for different road conditions. In addition, when the road conditions change, the installation method of the traffic light cannot be changed, and the entire light needs to be replaced, which is very costly. For example, if the originally narrow road becomes wider, the fixed arrangement of the lamp units may be difficult to adapt to the new needs. In addition, ordinary traffic lights often lack sufficient scalability, and the number or type of installation cannot be arbitrarily selected during installation. In addition, when it is necessary to increase or reduce the number of lamp units, the entire traffic light system may need to be modified or rebuilt. This not only increases the cost of modification, but may also affect the normal operation of traffic. Utility Model Content
