The design of the smart street lamp is inspired by the rings of the big tree. The annual ring is the chronicle of the life of the tree. The scheme adopts the design of surrounding suspended halo, just like the "crown of light" naturally born from the center of the annual ring. The light is warm but bright after soft diffusion.
It symbolizes the foundation and growth: just as trees take root in the soil, street lamps are the foundation of urban infrastructure; the concentric circles of annual rings imply the continuous evolution and development of the city.
