AI Technical Summary
Existing municipal road construction warning signs have poor light penetration at night and in rainy or foggy weather, resulting in a limited warning range and making it difficult for drivers to take timely evasive action.
A light-emitting component, including a lens and a locking mechanism, is installed on the warning sign. By rotating the lens and fixing it to the front of the warning sign, the lens collects and disperses light, increasing the light propagation distance.
In rainy or foggy weather, the warning range is increased so that drivers can see the warning lights from a greater distance, ensuring timely avoidance and improving the warning effect.
