The Japanese word 'sensai' refers to a form of delicacy, refinement and domestic tranquillity, a sensitivity with the double meaning of sensory perception and spiritual emotion. The company Check-up, specialized in innovative electronic devices, creates a range of lights for its business unit dedicated to multiple performance lighting. Characterized by a technology package that combines led and functional Wi-Fi with natural materials, Sensai lamps reflect the meaning of their name and are unique on the market. CCRZ uses these premises to design logo and visual identity. The symbol’s lines are inspired by the sine waves generated by the frequencies of sound and light and evoke the shape of the Samara, the winged seed.
