Description

Technical Field

[0001] The invention relates to the technical field of traffic signal lamps, and in particular to a traffic signal lamp used in rainy and snowy weather. Background Art

[0002] Traffic lights are lights that direct traffic, and are generally composed of red, green, and yellow lights. Red lights mean no passage, green lights mean passage is allowed, and yellow lights mean warning. Traffic lights are divided into: motor vehicle lights, non-motor vehicle lights, pedestrian crossing lights, direction indicators, lane lights, flashing warning lights, and road and railway level crossing lights.

[0003] In the prior art, a Chinese patent document with publication number CN215599821U proposes a traffic light for use in rainy and snowy weather, comprising a protective shell and a fixing plate. By utilizing a first motor to drive a lead screw to rotate, a second slider can be made to slide inside a rotating groove, thereby driving a wiping cloth at the bottom of the second slider to move. When the rain is too heavy, the movement of the wiping cloth can be utilized to wipe the signal light body, thereby improving the visibility of the signal light in rainy and snowy weather and improving the practicality.

[0004] However, in rainy and snowy weather, due to harsh environmental conditions, traffic lights are often affected by problems such as rain and snow accumulation and reduced visibility, making it difficult for drivers or pedestrians to accurately observe the instructions of the traffic lights. This situation not only reduces traffic efficiency, but may also increase the risk of traffic accidents. Traditional traffic lights are mostly fixed in design and cannot be adjusted or cleared according to actual needs, making it difficult to adapt to changing weather conditions.

[0005] Therefore, it is necessary to provide a traffic signal light for rainy and snowy weather to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention
