In response to the evolutionary transformation of Dingpu from an early industrial (coal) township into its present status as a technology center, the interior of the station is analogous to the transient qualities of light in relation to time. The character “C“, representing carbon, is adopted as a graphic icon, and implies the revolutionary progress from coal mines to high-tech carbon nanotubes.
Sunlight is captured through a row of reflective solar tubes running the length of the station mezzanine. Accompanied by supplemental light fixtures, natural light from the collectors resembles vibrant sunbeams that create virtual atriums, intuitively guiding passengers through high traffic areas.
Integrated lighting fixtures reinforce the design theme by abstractly expressing light waves, halos and radiancy, appearing as patterns on the ceiling, floor and walls. Programmable colorful LED light fixtures embedded in the concourse wall poetically reflect the changing environment. The steel spiral tube structure at entrance “B“ further strengthens the natural lighting effect with its transparent enclosure.
